Appointment

The drivers who were involved in the accident are often heard "Yes, he jumped out of nowhere!" That's why they're blaming motorcyclists for that. The problem is that the survey behind the driver is most often very scarce. The situation can be assessed by rear view mirror and side mirrors. But the data that the driver receives from the mirror is very limited. A space that does not fit into the driver's field of vision is called a dead zone.

In addition to traffic problems, the dead zone is interfering with parking. Particularly affected are newcomers who are not well aware of the dimensions of the car. They spin their heads in a dazed way, trying not to hit the cars on the side.

To fight the driver's blindness, we developed a device that helps control the distance to obstacles. The device was called a parking radar system, or a parquetronic. On the car's bumper, the sensors that calculate the distance to the objects behind, help to avoid collision with them. Later, the system was finalized and added to the fight with dead zones. The same principle, only now sensors are standing on the sides of a car and responding to moving objects, informing the driver of their approach.

The parking radar system is relatively young. It was first introduced in Germany in the early 1990s, and the initial company was the Audi company. In Russia, such a system appeared in the early 2000s. However, the name Parktronic is the name of the parking radar system in Mercedes-Benz cars. Other producers refer to it differently. BMW and Audi-Parkaspersistent. Opel uses the name "parking pilot."

Originally, such systems were installed only on expensive cars. In Russia, the parktrod is installed on the Lada Priora in the maximum configuration. However, the installation of the parking radar can be carried out on its own.

How it works

The system receives data using ultrasound sensors that are mounted on the body of the vehicle. Because it is an ultrasound, it will be called a sonar system, but it is known as "parking radar". The system works like bats. The sensor generates an ultrasonic signal that is reflected from the objects and returns it back. The system calculates the time at which the signal is returned and, based on this data, calculates the distance to the object. After receiving the signal, the parkroic informs the driver of the presence of the pump. There are several ways to proceed in this way:

-Visual alerting (the most basic method, the presence of an obstacle informs the LED);

-Output to the display (distance to barrier information is displayed);

-Voice alert (distance to obstacle);

-Combined alert (presence of camera allows to include "rear view", the vote duplicates information);

The dead zone sensors are working on a similar principle. They are an additional option of the parktronic. The point is that the sensors are located closer to the edge of the rear and front bumpers, allowing the movement of vehicles to be captured. The main difference is that the dead zone sensors only respond to moving objects, and the speed of movement should be greater than 10 km/h. The counter-action is ignored by the system. First and foremost, the movement is caught by the front sensors and the computer understands that the situation is not dangerous-the driver sees the oncoming car.

Operational issues

It is not possible to rely on sensor data completely. Like any electronics, the dead zone sensors periodically fail. The main problem is that if the sensor is very often actuating, it stops paying attention to it. The false positition is due to the fact that the sensor responds to certain objects, such as: chains, cables, objects with a height of less than 1 meter (which may be a motorcycle), objects are refracting the trajectory of the ultrasonic wave.

Also, care must be taken to ensure that the sensors are clean. The presence of snow or dirt on the surface may make it difficult to receive a signal.

Elevated noise levels are no less sponge than a dirty sensor. In addition to the above, the sensor may be extremely sensitive, leading to constant cork.

One thing to remember when using an instrument is that electronics are an assistant, don't treat it as an autopilot. It is necessary to evaluate the information obtained from the system visually by using side mirrors and a panoramic mirror in the passenger compartment of the car.
