Parktronics front and rear. Parktronics for 8 sensors

Even experienced drivers, perfectly feeling the dimensions of the car, front and rear parking sensors can significantly facilitate the process of parking in a confined space. This is especially true for large cities, where there is a permanent shortage of places where you could leave your car.

Principle of operation of the element

The algorithm of any parking radar in the car is quite simple and somewhat similar to the operation of a radar station. Ultrasonic waves emitted by a special electronic device, reflected from obstacles, are captured by sensors mounted in the front or rear bumper of the machine. The closer the obstacle is, the faster the ultrasound returns. The electronic control unit responds to the speed of the return of waves and gives out an appropriate signal, which can be sound, light or combined. Thus, it is necessary to install a parking sensor - and you can take your place in the parking lot with your eyes closed!

Basic types of radars

All the details presented today in the market can be conditionally divided into two large groups:

• Wire;
• Wireless.

As the name implies, the difference between these types is the presence or absence of cables connecting the electronic control unit to the ultrasonic reception sensors. In those cases where the front and rear parking sensors have a wireless principle, the communication between the computer and the sensors is carried out via radio waves.

Devices with video camera

However, parking sonars differ not only in the way they switch components between themselves. From a relatively recent time on sale there was a modification such as a parktronic with a monitor, which displays a picture from the built-in video camera. Such a device not only warns of sound and light signals approaching the obstacle, but also allows you to control the situation with your own eyes. In addition, some models are able to display all the necessary information not on the display, but directly on the windshield. This significantly increases the safety of the parking process for both the driver and the people around. It is known that from some objects (including animate ones) ultrasonic waves are reflected poorly or with significant distortions. However, the cost of such devices is much higher than conventional parking radar.

At the same time, on the market today you can find not only a parking sensor with a rear-view camera and a monitor, but a sonar with a lens designed for the front bumper. The expediency of installing such a device by many car owners is being questioned, since it is considered that the front camera provides the driver with "redundant" functionality. Say, everything is so clearly visible through the windshield, while the acquisition, installation and connection of the parking sensors with the front video review is quite expensive. Nevertheless, such a device can significantly help newcomers and improve the safety of driving. And to owners of cars with a high landing or with a long hood such radars can render really invaluable help.

Number of capture sensors

Modern parktronics front and rear can be equipped with a different number of sensors that capture ultrasonic waves reflected from obstacles. The market mainly presents models equipped with 4, 6 or 8 "eyes". True, one can also find obsolete structures equipped with only two sensors. Catchers are mounted, as a rule, in the bumper of the car. There are both standard devices installed on machines during the assembly process, as well as systems manufactured by third-party manufacturers.

Of course, the more sensors are captured, the better the parking radar and the viewing angle of the device. Compared with the "four-eye" sonar, the parking sensor (8 sensors) allows you to mount the capture devices with a much smaller pitch. In addition, this scheme allows you to set the "eyes" of the parking radar to the corners of the bumpers and even on the sides of the car body. Which greatly enhances the device's overview. However, at the same time the price of such a device is much higher, and repair of parking sensors is more expensive.

Tape

In recent years, so-called band parking radars have been gaining in popularity. Unlike traditional models, they use non-point capture devices of the reflected signal, but a special metallized tape that can catch ultrasound. Advantages of this type of parking sensors are quite obvious:

• A wider coverage area;
• Absence of dead and blind zones ;
• Versatility and the ability to mount on any model of the car.

However, the front and rear parking sensors, made in the form of a belt, should be chosen with caution. First, the quality of such devices depends very much on the manufacturer. Today, there are many elements of no name on the market, mainly of Chinese origin. They can work incorrectly, and their service life leaves much to be desired. Therefore, it is more expedient to choose products of well-known brands and manufacturers.

Secondly, tape parktronic has its nuances during installation and configuration. As a rule, it is installed over the bumper, which means that it is necessary to perform a certain cycle of additional works to disguise it and adapt it to the overall appearance of the car. Otherwise it will catch your eye, spoiling the impression of the exterior of the vehicle.

Well and at last, unlike traditional models, repair of a parktronic of a tape type represents rather difficult and labor-consuming process. Often, if a metallized capture tape fails, there is no other way out, as its replacement with a new one.

Installation and configuration

In order to install a parking aid on a car, it is best to turn to highly qualified car service specialists for help. Mounting devices of this type on its own is strongly discouraged. The fact is that although the appropriate instruction is applied to the parking sensors, its installation requires a number of works that require not only specific skills and skills, but also the relevant equipment and tools.

The main problems in the installation of radars

The main difficulties in installation are related to the following aspects:

• Mounting of sensors. As a rule, for installation of trapping sensors it is necessary to drill holes in the bumper of the corresponding diameter.
• Setting the eyes. Capturing sensors should not only be securely fixed, but also correctly oriented in space. Otherwise, the system may not work correctly, directly threatening security.
• Installation of electrical wiring. Wired parking sensors require the services of a professional auto electrician who can connect the sensors with the electronic control unit.

Thus, often attempts to install the parking radar independently, regardless of its type, can entail not only the incorrect operation of the entire system, but also damage the appearance of the car or its interior.

Adjustment of complex parking systems

If you install even an ordinary radar model by your own, it's quite difficult, then what to say about a parking sensor with a rear-view camera and a monitor! After all, he has much more wires, and the accuracy of installing instruments should be much higher. In addition, the adjustment and adjustment of complex systems requires very deep theoretical knowledge and rich practical experience. Especially if they are equipped, for example, with the functions of outputting information on the windshield of the car.

Repair and service

Modern models of parking radar are quite unpretentious in caring for themselves. If you do not take into account the periodically arising problems with electronics or wiring, the main preventive measure is, in fact, the timely cleaning of sensors and lenses from dirt, dust and snow. But even the best parktronics are out of order from time to time.

The main reason for the breakdown of the vehicle management assistance system is the failure of the sensors. With known skills and skill they can be replaced on their own. But if the electronic control unit fails or the electrical wiring is damaged, then it is worth turning to professionals. They not only "reanimate" the system, but will also re-create its fine tuning.

On the radar, hope, and he is not bad

Of course, the devices discussed in this article are able to provide significant assistance to the driver in cramped urban conditions. However, no matter how good a parking sensor is, you should first of all rely on yourself. To duplicate the work of the electronic system with your own eyes will never be superfluous!
