To remedy the situation, there are special devices, some parking assistants that are built into the car and help the driver navigate in space by scanning the distance to the nearest obstacle.
There are many varieties of such parking sensors, each of which has its own characteristics, but you need to know how to choose parking sensors (parking sensors) in 2019 so that they are reliable and at the same time easy to use.
General information
Help behind the wheel, especially for beginners, is always welcome, but you can’t always carry a more experienced driver with you who will tell you how to drive correctly and when to turn.
Therefore, technical devices called parking sensors were invented. They greatly simplify the process of parking the car, while minimizing the chance of colliding with objects around.
The device fulfills the main goal - to warn the driver about the danger by sound signals, and expensive models also have rear-view or front-view cameras that allow you to monitor the situation on the road as objectively as possible.
What it is
Parktronic, which is also called a parking radar, is a specialized device that monitors the situation around and warns the driver in case of a risk of a critical approach to another object, simply speaking, a collision.
Parktronic consists of a set of parts that are mounted in the car bumper or trunk lid, and also placed inside the car.
The sensors themselves work on the principle of an echo sounder, emitting a signal that reflects off other objects and returns back.
The computing device processes the received data and gives the result in the form of a distance to obstacles, it can be a signal of different strength, duration, or information on the service screen of the system.
So, a garage gadget will allow you to quickly and easily drive to the place where the car stops.
Types of modern parking sensors
All existing parking sensors differ in their design, as well as the presence of additional devices that are auxiliary.
Thus, the following types of parking devices can be distinguished:
| Standard, ultrasonic | It has a different number of sensors, as well as an audible warning system, the signal of which is transmitted to the driver. As a rule, the more often the signal sounds, the closer the obstacle, but there is also a minus, which is that the driver does not know which side the obstacle is closer from and has to park longer |
| With a camera | In addition to sound signals, such parking sensors allow you to see the situation from behind using a camera that displays video on the car display. Thus, the driver can understand what kind of obstacle is in his way, and what he needs to do |
| Wireless | Instead of the wires that are found in parking sensors, information is transmitted to the display or speakers using a radio signal. It is put in cars that did not have parking sensors initially, so as not to carry out a lot of work and not spend a lot of time on installation |
| Tape | Instead of the usual point sensors, a metallized tape is attached to the rear bumper, which makes it possible to practically avoid dead zones. In general, the electromagnetic parking sensor works on the same principle as a conventional one. |
Current regulatory framework
Parktronics are used to park according to all the rules described in.
The systems allow you to become so as not to interfere with other drivers and without driving onto the sidewalk, while not creating emergency situations during parking.
If the motorist breaks the rules and becomes wrong, closing part of the road, or commits an accident, then the punishment for him will be chosen according to the rules.
A fine will be assigned for parking violations, and if an accident was committed that led to human injuries, then you can lose your rights and even get criminally liable for this.
Installation procedure for parking sensors
In order to install parking sensors, you do not need any special skills. To do this, it is often enough to make a few holes in the bumper, and then connect all the wires correctly.
First of all, you need to understand that a special drill can also be included with the system for making holes of the desired diameter, but it will not be difficult to purchase it in a store, you just need to measure the diameter of the sensor and purchase a drill a couple of millimeters larger.
To install and connect the parking sensors, you need to stock up:
- parking system;
- milling cutter;
- drill or screwdriver;
- keys;
- pencil, masking tape, tape measure and tester.
After all the details are taken, you can proceed with the installation. The first step will be to make holes for the sensors, for this you need to remove the bumper, but if you previously had experience with a drill, then you can not dismantle it.
First you need to mark the places for the holes, while you need to be guided by the instructions, which spell out the distance between the sensors themselves, as well as the scanners and the ground.
After marking, drill the marked points, while holding the drill only perpendicular to the bumper.
After installation, they are fixed with complete rings, it is necessary to install the sensors in the correct sequence.
Latin letters can tell about it, according to which nodes are placed from left to right. The signal processing unit from them is placed in the trunk, in which you need to remove the casing, and wind the wires from the sensors together and lead them into the trunk through a technical hole, it will not be difficult to connect them to the unit.
In order for the parking sensors to work correctly, it must be connected to the reverse lights on the positive wire.
To do this, it is better to use special rivets with which the power wire of the unit is attached to the power supply of the rear light.
Connecting the display will not be difficult, the main thing is to properly wire it, this can be done both through the interior and on the side using technological holes and adhesive tape.
Distance between indicators
In order for the sensors to work correctly, it is necessary to observe a distance between them at the level of 20-30 centimeters during installation, but this depends on the number of sensors and their interaction.
Before you test the parking sensor, you need to understand where the most accurate distance data is located.
Most often they are indicated in the operating instructions of the devices, and it is they that should be guided during installation.
Since different techniques work with differences, the universal rules may not work in this case, and as a result, the radar will not work correctly.
Optimal quantity
If the driver has certain driving skills, but has recently purchased a car or wants to install parking sensors for reassurance, then a set of four sensors will suit him.
Thus, he learns about the critical danger. For beginners, a set of six sensors can be recommended, which scans more space, which means it gives more accurate data and captures even “dead zones”.
Principle of operation
All parking sensors work on the same principle - generating waves and catching them back, and subsequently processing them with the help of computer technology.
This nuance allows you to level the differences between different types of parking sensors, which in fact differ only in signal quality, viewing angle and, of course, brands.
Front
The front parking sensors, as the name suggests, are used in the front of the car, while it is at least slightly different from the rear.
For the front radar, a much shorter range is required, since the driver sees most of the distance himself, the optimal indicator may be half a meter or a meter maximum.
Front parking sensors differ in connection methods, for example, they can be connected to a speed sensor or brake pedal, but like the rear version, they can be turned on by a button.
The principle of operation is no different - these are all the same waves that are reflected from an obstacle.
rear
The rear parking sensors also work according to the scheme for generating waves and reflecting them back, as well as subsequent calculations.
But they differ from the front ones in that they have a longer operating range, and are also often equipped with a camera and are supplied in larger quantities, since the dead zones will thus be much more visible.

How much does it cost to put a parking radar on a car (price)
Prices for the installation of parking sensors differ, but are generally similar. The most expensive installation of the sensors themselves, as well as the camera, will be the cheapest to install a monitor, since this is the most troublesome thing.
Thus, a complete installation of a standard parking sensors for 4 sensors will cost about 8 thousand rubles, because you need to add the cost of consumables, if any, to the payment, as well as the work itself, since the installation of parking sensors, although not considered a difficult procedure, requires a certain amount of time and strength from the masters.
Do-it-yourself installation
Installing a do-it-yourself parking system is good because it does not require payment of labor, that is, paying for the parking system is all that should be spent.
But if there are certain risks that are associated with improperly performed work.
First of all, this concerns electronics, because if you connect it incorrectly, not only the device itself, but also car parts, the repair of which will be quite expensive, may well burn out.
The most common job difficulties
Every year, thousands of new cars appear on the streets of modern cities. At the same time, the number of parking spaces is growing less actively, and motorists are forced to park more densely, which inevitably leads to an increase in the number of traffic incidents. Help to avoid unpleasant situations on the roads parking sensors - a parking radar that helps the driver to safely park the car in any conditions. This device will be especially useful for beginners and those who have not yet mastered parking a car in difficult urban conditions.
These devices come in several types, and in this article we will look at the most popular of them - ultrasonic. The principle of operation of parking sensors is simple: special sensors are installed in the bumper of the car, which transmit and receive acoustic signals. The device calculates the distance to obstacles based on the time it takes for sound to travel from the sensor to the obstacle and back again. This is possible because the speed of sound is a constant value. 
The driver receives a visual, audible or complex signal. In some types of parking sensors, an LCD display is installed, which displays the position of the car relative to obstacles and the distance to them. As practice shows, it is the sound signal that is best perceived, but it rather depends on the habit.

What do we need to install?
To install parking sensors with your own hands, you do not need any professional skills. An ordinary motorist can cope with this task by force. All that is required for this is to drill a few holes evenly and connect the wires correctly. Most of the necessary tools can be found in the garage of any driver.
The set of most parking radars consists of:
- sensors (from 2 to 8 pieces)
- connection cables
- screen
- signal processing unit.
Also, some models come with a cutter for drilling holes for sensors and various useful little things. But if it is not included in the kit, this is not critical - you can measure the diameter of the sensor and purchase a drill at the nearest store. However, it should be taken into account that the cutter diameter must be 1-2 mm larger than the sensor diameter.
To install and connect parking sensors, we need:
- the device itself
- cutter for drilling holes for sensors (often comes with parking sensors)
- drill (you can also use a screwdriver)
- a set of keys
- pencil, electrical tape or clamps, tape measure and tester.
All cars are different and each case is unique in its own way, so other little things, such as pliers, a soldering iron, or a car electrical diagram, may be required.
We install parking sensors with our own hands
This installation scheme is universal, and is suitable for most cars. Sensors and a camera are mounted in the front and rear bumpers, which are connected by wires to the control unit. The parking sensors display can be installed either on the dashboard or in the rear of the cabin and is also connected to the unit. 
Installing the rear parking sensors
It is necessary to start the installation of the system by drilling holes for the sensors. This is perhaps the most responsible task and should be approached with special care. On some vehicles, it is not necessary to remove the bumper, but if it is more convenient for you, it is better to remove it.
To begin with, we outline the places on the bumper where we will install the sensors in the future. You can find detailed installation requirements in the instructions for the parking sensors, such as the optimal distance between the sensors and from the sensors to the ground. These requirements are very important, and they must be taken into account when basting holes. Next, we glue the mounting tape to the places where we will drill, and mark the centers of the holes with an awl. 
Seven times measure cut once! It will not be superfluous to check the markings of the holes again. Mistakes made at this stage cannot be corrected!
Using a cutter, we drill holes in the bumper that were previously marked for the rear parking sensors. It is important that the sensors after installation be directed strictly horizontally, so drilling should be perpendicular to the plane of the bumper. 
After that, the sensors are inserted into the holes with the sensors outward (wires inward). The bumpers of some cars have a lining under the plastic - a damper. In this case, a piece of wire or a nail will help you to push the wires through. Having previously made a hole in the damper for the wire, wrap the cable to the nail with electrical tape and pull it inward. 
Next, we insert the sensor into the hole and fix it on the back side with special rings that should be included. It is also important to install the sensors in the correct sequence. They are marked with Latin letters A, B, C and D and must be installed on the bumper in the same order from left to right. 
Often the sensors are black or silver and, if necessary, they can be repainted in body color (bumper). This procedure does not affect their sensitivity and durability in any way, and your car looks more beautiful. You can pick up the paint “by eye”, or accurately determine the color using computer selection. 
As a rule, the signal processing unit is installed in the trunk, although it can also be mounted in the inside of the wing or under the dashboard in the cabin. We will consider an example of the most common solution.
We will work under the bumper and in the trunk. First of all, we free the trunk and remove the trim. We wind the wires from all sensors together. This can be done with electrical tape, clamps, or run the wires through the corrugation, which will also protect them. We wire the wires wound together under the bumper into the trunk through the technological hole. If it is missing, we drill a new one and fill it with sealant after pulling the wires. 
Next, we need to choose a place where the signal processing unit will be installed. This place should be relatively safe for the block, as it can be torn off by the cargo that will be transported. The block itself is attached to any surface using double-sided tape - just tear off the film and attach the block (preferably to a fat-free surface). 
The parking sensors are activated at the moment when the reverse gear is engaged. Therefore, after fixing the signal processing unit, it must be powered from the reversing lamps, observing the polarity. The first step is to get to the rear light wires and determine which one is “plus”. Often this wiring consists of cables with black and red insulation, in which case the red wire is a "plus". Otherwise, "plus" must be determined using a tester.

Do you know the difference between antifreeze and antifreeze? about which coolant is better to choose.
There are two ways to connect wires:
After that, we connect sensors to the block - each wire from the sensor and each connector in the block are marked accordingly.
Now let's think about where to put the display and install it. As a rule, it is installed on the dashboard. But some prefer to install the display in the rear so that it can be seen through the rearview mirror. The display, like the block, is attached to a flat surface with double-sided tape. Whichever location you choose for the display, the next step is to connect it to the signal processing unit.
Important! When installing the display in the rear, you must take into account the fact that you will look at it through a mirror. This means that the obstacles on it will also be displayed in a mirror image, that is, vice versa! To make the display correct relative to you, you need to change the order of the wires of the sensors that are connected to the unit. That is, change A, B, C, D to D, B, C, A.
The rear-mounted display has the advantage of not having to run wires across the cabin to the dashboard. In this case, the wiring is pulled through the technological hole under the seat, then under the skin between the side and the roof of the car. In the case of a front-mounted display, the wiring is located under the side skirt trim or under the floor mats. 
It is better to secure all wiring with clamps or electrical tape. The same applies to extra pieces of wire that can knock on the pits. It may happen that in the sun the fender of the car heats up, and the block attached to the double-sided tape can slide off. After the installation is completed, turn on the ignition, then reverse gear and see if the screen lights up. If it lights up, then you have correctly installed the rear parking sensors!
Installing the front parking sensors
The principle of installing the front parking sensors is the same, but there are some differences. In this case, we need to run the wiring through the hood and interior of the car to the trunk, where the signal processing unit is installed. On some vehicles, before installing the front parking sensors, you need to remove the grille and the air duct pipe.
Then everything is according to the instructions - we mark and drill holes for the front parking sensors. We use wire to push the wire under the bumper and fasten the wiring with electrical tape or clamps. Through the technological hole, the wire is led into the engine compartment. In some cases, the washer reservoir will interfere with the wires, so it must be removed.
It is better to run the wire from the front left sensor on the other side of the engine compartment under the battery. In order to stretch the remaining wires, you can use a standard corrugation, if any. The cable is pulled into the cabin through a technological hole.
Now let's decide how we will activate the parking sensors apron. And there are several options here:
And finally, we bring the wiring through the passenger compartment to the place where the signal processing unit is installed. In our case, this is the trunk. We connect the wires of the front parking sensors according to the instructions, in the same way as with the rear one.
Parktronic does not work, what should I do?
There are many reasons why the parking sensors may fail or not work after installation. Therefore, we will consider two cases:
New parking aid not working
At the beginning of the article, we recommended checking the performance of the device before installing it on a car. If it worked before installation, you should check the connection of all the main nodes. All components must be connected according to the instructions that come with the kit. Check if you are properly powered by the reversing lamp or ignition. Also, do not exclude the possibility of a factory marriage.
The parking sensors worked, but something went wrong
The fastest and most reliable way to find out the cause of the breakdown is computer diagnostics. Now this service is provided by many auto repair shops. If you decide to find the cause of the breakdown yourself, we will try to help you. Often the cause of all problems are sensors, and it is on them that you should pay attention in the first place. One of the most common problems is a constant signal. The reason for this may be a foreign body that “stuck” on the sensor, as well as oxidation of the contacts and a short circuit.
Also, the sensors are sensitive to water and may give false signals during rain or after washing. In this case, drying, for example with compressed air, will help. At sub-zero temperatures, especially in severe frost, the sensors may also lose sensitivity. But this does not affect their further performance.
In conclusion, before leaving the road, you should test the parking sensors with different obstacles and in different modes. This will allow you to understand in which situations the system can give a false signal and in which a real one.
Video example of installing parking sensors with your own hands
One of the most difficult driving maneuvers is reversing. But whether we like it or not, we have to use such a mode of movement all the time, especially when parking a car. To secure the control of the machine in such a situation, the parking sensors were born.
What is it, and what is the parking sensors device
This device has many names. It is called parking sensors, and parking radar, and parking sonar. From these names, the principle of its operation becomes clear - detecting an obstacle, measuring the distance to it and warning the driver. This happens as follows - when the reverse gear is turned on, the ultrasound generator, which is part of the parking sensors, begins to radiate.
If an obstacle appears along the path of the car or nearby, a reflected signal appears from it, which is perceived by the parking sensors circuit. Based on the delay time of such a signal, the system determines the distance to the obstacle and warns the driver of the car about this using the signaling and indication means provided for by the design of the product.
What is the parking sensors system
To understand what such a device is, just look at the figure:
It consists of:
- the electronic unit;
- sensors placed on the bumper of the car;
- display and indication device.
This is a fairly enlarged image, but it allows you to understand what the product is. The existing types of parking sensors are quite diverse and numerous. You can define the following signs by which they differ from each other:
Number of connected sensors. There may be two, or there may be eight. The possibility of detecting an obstacle when maneuvering in reverse and the cost of the parking sensors itself depend on the quantity. If the car is equipped with two sensors, then the probability that the obstacle will go unnoticed is quite high. If the device contains eight sensors, then the probability of error is minimal. 
Way to display distance. The system can use distance indicators with one scale, with two scales and a digital display of the distance to the obstacle.
A means of displaying information. For parking sensors, the data that the device receives as a result of its operation can be displayed on:
- special device;
- liquid crystal display;
- windshield;
- car rearview mirror.
A method of transmitting information to the electronic control unit from sensors. A system such as parking sensors can use data transmission both by cable and radio channel for these purposes.
The use of additional devices. There are special systems that additionally use a video camera in their work, which provides a display of the space behind the car in the rear-view mirror. It is believed that such parking sensors with a rear-view camera create opportunities for the safest conditions when maneuvering in reverse. At the same time, one should not forget that although a parking sensor is installed on the car, the rear-view mirror also, with no less efficiency, allows you to assess in time the presence of obstacles behind the car.
Sensor locations. Initially, it was planned to place them only on the surface of the rear bumper of the car, but later the parking sensors began to use sensors installed on the front bumper.
How to connect parking sensors
This task is responsible, but it is quite possible to perform it on your own, following the instructions. As a rule, the wiring diagram requires connecting sensors, a display device and an electronic unit. It is usually installed in the trunk of a car in any convenient place. 
The next task of the wiring diagram involves the installation of sensors. If more than two are planned, then first of all, the extreme ones are installed, at the bending radii of the rear bumper, then the rest are placed at the same distance. Before installing them, the surface is prepared, cleaning it from dust and dirt, and after that it is marked on the surface of the rear bumper where they will be located. The system usually provides for a certain location of the rear view sensors, including, as a rule, it is necessary to maintain a distance of fifty centimeters from the ground. 
Holes are drilled in the marked places of the rear bumper, in which sensors are then installed. In order for the system to work reliably in the future, they are additionally attached to the bumper with glue or sealant. After that, you need to connect the sensors to the control unit, as provided by the parking sensors circuit. If the display device is planned to be located on the front panel or on the rear-view mirror, then the wires for connection will have to be laid under the interior trim, for which it will have to be removed.
It is best to combine all the wires used to connect the rear view sensors into a single bundle using clamps; additional measures must be taken to protect against damage at the transition points through the holes. After the connection diagram of all devices is completed, the parking sensors must be tested. To do this, the parking sensors system is checked under different conditions for the possibility of detecting obstacles when maneuvering. If the product works correctly, detects and warns about the presence of obstacles in a timely manner, then you have managed to connect the parking sensors. 
Parktronic for cars, its possible failures and malfunctions
As a rule, the causes of parking sensors malfunctions are failures of sensors and wires in the harnesses. Of course, it is possible that the failure occurred in the electronic control unit, due to which the parking sensors system itself either stopped working or works with violations. But such a failure is quite rare.
For example, an external manifestation of a failure can sometimes be a long squeak that the system issues for no apparent reason. In this case, a possible cause may be splashing of the rear view sensor with dirt, after removing the dirt, the parking sensors will be able to work as before. Another reason may be the closure of individual wires that are connected to the central sensor unit. In this case, the correct operation of the product will be violated, and diagnostics will be required to restore its performance.
Moisture closure of wires for connecting sensors will also appear, as a result of which the correct signal flow pattern will be violated. However, after drying the wires, performance should be restored.
By itself, a device such as parking sensors cannot be considered an essential element of a car, but nevertheless, it turns out to be useful when performing complex maneuvers, especially for novice drivers. The parking sensors can be of different types and designs, but in any case, for its operation, the connection of rear-view sensors is required.
Parktronic is an electronic vehicle device designed to detect interference when maneuvering a vehicle in a confined space. Actually, this is a miniature car radar.
Sensors mounted on the front and rear of the vehicle emit an ultrasonic signal. If the signal stumbles upon an obstacle that has arisen, then it, reflected from it, returns back.
The parking sensors process the reflected signal and provide the driver with information about the interference that has occurred. Information can be provided to the driver by color change, sound, image. It can also be provided as a combination of several waveforms. For example, an image and a sound signal.
Parktronic is an indispensable assistant in conditions of poor visibility, limited visibility, difficult maneuvering and parking conditions. Parktronic is especially useful for novice drivers who do not yet have driving experience. It will facilitate the management of a vehicle by parking sensors and experienced drivers.
Complete set of parking sensors and division of devices into groups
The standard equipment of the parking sensors includes
- Sensors for detecting interference. Depending on the model, the principle of operation, their number may be different. Typically, the standard equipment of the device includes from 2 to 8 sensors.
- Electronic control unit. Designed to process the signal received from the sensors.
- Means of displaying information. Speaker, LED, possibly LCD.
- Mounting wires.
- Fasteners.
- Accompanying documents. Description of the device, technical data sheet, installation instructions, manufacturer's warranty. The warranty is valid for three years.
The device is mounted both on the front of the car and on the back. It can be installed both on the front bumper and on the rear. The sensors can also be mounted in the view mirrors.
Types of parktronics:
Technical characteristics of parking sensors
For example, here are the technical characteristics of the parking sensors built into the mirror:
- operating range of the device from 0.3 m to 2.5 m;
- waterproof;
- operating voltage in the range from 9 to 16 V;
- operating temperature from -45 to +80 C;
- alarm, level > 80 dB;
- the error in the readings of the sensors is 10 cm;
- detection angle - 80 degrees, both vertically and horizontally;
- sound signal;
- digital display;
In this example, we showed what characteristics you need to consider when buying parking sensors. Of course, different models and parameters are different. The choice of a device with certain characteristics depends, for the most part, on where the parking sensors will be installed in the car. We only note that interference by any device can be determined at a distance of 0.3 meters to 2.5 meters.
All models of parktronics can be divided into three groups according to their characteristics, and therefore, according to their cost.
To the first, we will include parking sensors that have a relatively low price and call this group budget.
This group is characterized by the fact that there are usually two, sometimes three sensors in the kit. They are most often installed on the rear bumper. The viewing angle of such devices is small, there are dead zones, i.e., areas that the device does not “see”. For example, a parking sensor with two sensors does not detect interference that is in the middle of the sensors.
The next group, which we will call the middle one, includes parking sensors already with 4 or 6 sensors.
They are also mounted on the rear bumper. Parktronics of the middle group no longer have most of the shortcomings. belonging to the budget group. Such parking sensors, of course, are more expensive.
The third group is the highest. In a set of such parking sensors, there can be 8 sensors, and 10.
They are installed on both the front bumper and the rear. That is, they give a complete overview of the state of motion both in front and behind the car. Such systems are, of course, expensive. But they are reliable.
Installation of parking sensors
Installing sensors on the front bumper
The parking sensors control unit is usually placed in the trunk. Installation of parking sensors, of course, is better to start with the rear bumper. But we will first describe the installation of sensors on the front bumper, and then on the rear. Consider how the parking sensors are mounted with two front and two rear sensors.
Before installation, it is recommended to remove the bumper from the car. Naturally, it needs to be cleaned and washed. It is possible that the bumper already has factory markings for installing parking sensors. If it is missing, we will make the markup ourselves. It should be noted that the sensors are installed at a height of at least 50 centimeters from the ground. We mark the installation locations of the sensors so that they are at an equal distance from each other, from the edge of the bumper.
Sensors should not run into the license plate and its molding. Then we take a drill with a thin drill and make holes in the bumper. With a special cutter, it is included in the parking sensors kit, we expand the holes. We insert sensors into the holes. We fix the wires of the sensors with clamps. They are attached to the bumper. The sensors must be at right angles to the ground.
If the bumper of the car is concave, then sensors with a special corrective housing are used. Then we start the wires in the salon. It is better to drive them through the engine from the right side. In the cabin, the wires are passed through the glove box. The wires go to the control unit through the side rack. To do this, remove the seal from it and pass the wires through the resulting cavity. In the trunk, we connect the wires from the front sensors to the control unit. We remove the rest of the wires under the skin.
Mounting sensors on the rear bumper
The actions are the same. as with mounting sensors on the front bumper. Only previously in the trunk compartment we shift the trim. The wires leading to the sensors can be passed through the rear lights.
The device must be grounded. To do this, there are grounding points on both sides of the trunk. An alert device, such as a display, is installed at the front of the vehicle. Most often on the left side. It must be borne in mind that the parking sensors operate on DC power. Therefore, during installation, you must follow the wiring diagram.
Usually such a scheme comes with the device itself. Do not confuse the "plus" and "minus" circuits, the device will not work or distortion will occur. The kit does not come with a mounting wire for wiring around the car. Therefore, you will have to buy it yourself. You will need to buy a wire to connect the power, to connect the warning system. Corrugation for protecting wires, electrical tape, fasteners, in particular, clamps.
An approximate wiring diagram for parking sensors is shown in the picture below:
All work on installing parking sensors takes no more than 3 hours.
Parktronic testing
The most reliable test of the parking sensors is testing it on a special stand. In such a test, you can fully check its performance in a variety of modes. If you check the parking sensors yourself, then it is better to do this on a well-studied route, where you know all the obstacles, for example, when parking near your house. Check how it reacts to interference at different distances. How it behaves when the environment changes. For example, when appearing near a car. But it's better not to be lazy, take it to a car service and drive it on the stand.
You can find more information about working with specific parking sensors at the following links:,).
The cost of parking sensors and the cost of installation
The cost of parking sensors, depending on the model, configuration, manufacturer, ranges from 900 rubles to 11,400 rubles. The price is also affected by the region in which the device is sold.
Prices for installing parking sensors range from 1000 rubles. For example, such a price for installing parking sensors is valid in the Republic of Mari-El.
Separately, parking sensors are practically not sold. The product is almost always sold with installation. That is, the cost of installation is included in the price of the product. In Moscow, parking sensors for the rear bumper of the PARKMASTER brand can be purchased with installation at prices from 5300 rubles to 6100 rubles. Naturally, the price depends on the modification, configuration of the product. There is a benefit to this. Along with the installation, you also receive a guarantee from the company that produces the installation. Within 3 years you can count on warranty service and repairs.
Parking radar allows you to safely drive in tight spaces. With the help of sensors, the driver controls the distance of the car body from the nearest objects, reducing the risk of a collision. At the same time, the quality of the parking sensors depends on the configuration of its installation. There are different ways of integration and location of sensors, as well as channels for their interaction with the control unit. Manufacturers recommend installing parking sensors with maximum coverage of the space in front of the car, but this is not always advisable. When choosing, it is important to take into account many nuances, which will be discussed below.
Number of sensors and configuration of their placement
It is usually practiced to install sets of 4, 6 and 8 sensor emitters. During operation, each sensor, by processing an ultrasonic pulse, makes it possible to estimate the distance to a third-party object. Sensing elements are placed at the back and front of the car, and their specific number on each side depends on what equipment the parking sensors provide - 6 sensors are usually divided into 2 and 4. 2 are installed in the front, and 4 in the back. The unevenness is due to the fact that the most dangerous "blind" zones are behind.
The maximum set for 8 sensors assumes a single layout - 4 sensors on each side. Experts do not recommend using 6 sensors on one side for the reason that they will provide too high sensitivity and a corresponding increase in the percentage of false positives. It is also recommended to install parking sensors in compliance with the distance from the ground and the distance between the individual emitters. The height of the installation point from the roadway, according to the instructions, is 55-60 cm. The gaps between the sensors must be maintained in the range of 10-15 cm.
Punch-in installation
This is a classic mounting method that involves creating a hole in the body or bumper of the car. First you need to choose the optimal place for sensor integration. The mounting point should be located away from the protruding structural parts of the machine, including spare wheel fasteners, towing eyes, etc. Next, a cable is connected that will connect the sensor and the control unit. Wires should not be placed in close proximity to the exhaust system or power harnesses of local electrical equipment. It is desirable to physically install the parking sensors in the holes made with a complete drill. In this case, the optimal diameter will be provided without the risk of getting a narrowed or expanded niche. The sensor is installed in the prepared hole using rubber seals, which are also supplied in the kit.
Overhead installation
This method has the advantage of eliminating the need for a sensor integration hole. It should be noted that the formation of the mounting niche is due to the need to fix the sensor element, as well as laying the communication channel through the wiring. It is easier to install parking sensors in an overhead way, since in this case it is enough to use a special adhesive solution included in the kit. Actually, according to the same principle, the electromagnetic tape of parking sensors is fixed - an analogue of ultrasonic sensors.
As for wiring, overhead models most often work wirelessly. Therefore, the question of how to properly install an overhead type parking sensor involves only correct marking, landing on glue and further configuration.
Assembly of other functional components
The minimum equipment of the parking radar, in addition to sensors, also provides for the presence of a display. The first one processes the signals from the sensors, and the second one presents the driver with specific data on the distance to objects. The controller unit can be installed in the luggage compartment, but in such a way that it is reliably protected from mechanical damage, vibration effects and moisture. Installation is carried out using a special metal frame into which the block itself is inserted. How to install parking sensors yourself? To do this, it is enough to arm yourself with a screwdriver, complete screws or bolts. It is necessary to screw the frame into the prepared technical holes, and then install the controller with screws of a different format. The display is installed in a place visible to the driver - usually on the front panel. It can be fixed with the help of brackets or put on Velcro, which, however, is unreliable.
Wiring diagram
Before connecting, disconnect the control unit from the power supply, and then visually determine the wiring channels. For example, parking sensors, 6 sensors of which are connected via the classic wired method, will provide for a two-way connection to the controller unit. That is, 4 lines will need to be connected to one side of the relay, and 2 to the other, directed towards the driver. On the front front side, the control unit relay usually has connectors for connecting an information wire, a power circuit, etc.
Wireless systems only require the connection of a controller box and, in some cases, a display for power supply. Power must be provided only from the battery and the on-board electrical network. Pulse sources are not suitable for such a connection scheme. You should also evaluate the compatibility with the voltage indicator. For example, Sho-Me parking sensors in standard versions can only be connected to sources with a voltage of 10-15 V.
To ensure stable signal reception, it is recommended to initially observe the correct position of the sensors. Usually, do-it-yourself installation is implemented without taking into account the orientation side of the sensitive sensor. Experts advise directing the wide part of the rim up. By the way, the premium parking sensors Sho-Me in the Y-2616 modification includes 8 large sensors with pronounced metal rings. When installing them, it is especially important to observe this rule. Another tip concerns wiring insulation. All supply cables must not only be protected, but also located in channels that exclude contact with a metal structure or other electrical equipment.
Conclusion
The installation technology of the parking radar is much more complicated than this. This is due to fierce competition between these driver assistants, while in practice the sensors are more effective. And yet, a well-thought-out layout of sensors and communication lines helps to install parking sensors without any problems. The price of such services in specialized workshops can vary from 5 to 10 thousand rubles. depending on the complexity of the work. For an ordinary motorist, the main problem of this operation will be the laying of cable infrastructure. Working with the onboard electrical network in itself imposes a high responsibility. However, you can choose an alternative method of wireless installation.
