Even experienced drivers who feel greatdimensions of the car, parktronics front and rear 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 one could leave your car.
An algorithm for the operation of any parking radar inthe car is quite simple and somewhat reminiscent of the 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.
All the details presented today in the market can be conditionally divided into two large groups:
As the name implies, the difference between these typesconsists in the presence or absence of cables connecting the electronic control unit with the ultrasonic reception sensors. In those cases where the front and rear parking sensors have a wireless principle, communication between the computer and the sensors is carried out via radio waves.
However, parking sonar differ from each othernot only the way of switching components among themselves. From a relatively recent time on sale there was a modification, such as a parking sensor with a monitor, which displays a picture from the built-in video camera. Such a device not only warns of approaching obstacles to sound and light signals, 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.
At the same time, it is not onlyParktronic with a rear-view camera and 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 believed that the front camera provides the driver with "redundant" functionality. Say, all and so clearly seen through the windshield, while the acquisition, installation and connection of the parking sensor 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.
Modern parktronics front and rear canbe equipped with a different number of sensors that capture ultrasonic waves reflected from obstacles. The market is mainly represented by 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.
Of course, the more capture sensors, theabove the possibility of a 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.
Recently, more and more popularitycollect so-called band parking radar. Unlike traditional models, they do not use 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:
However, the front and rear parking sensors, made in the form of a belt, should be chosen with caution.
Secondly, the tape parktronic has its ownnuances during installation and configuration. As a rule, it is installed over the bumper, which means that it is necessary to carry out 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.
And finally, unlike traditional models,repair of parktronics tape type is a fairly complex and time-consuming process. Often, when a metallized capture tape fails, there is no other way out, as its replacement with a new one.
In order to install thecar, it is best to ask for help from highly qualified car service specialists. Mounting devices of this type on its own is strongly discouraged.
The main difficulties in installation are related to the following aspects:
Thus, often attempts to selfinstallation of a parking radar, regardless of its type, can entail not only the wrong operation of the entire system, but also damage the appearance of the car or its interior.
If you install even an ordinary radar modelits own quite difficult, then what to say about parking sensors 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.
Modern models of parking radars are prettyunpretentious in caring for themselves. If you do not take into account the periodically occurring 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.
Of course, the devices discussed in thisarticle, are capable to render the essential help to the driver in the constrained city conditions. However, no matter how good a parking sensor is, you need to rely first of all on yourself. To duplicate the work of an electronic system with your own eyes will never be superfluous!
