How to judge the distance of Mercedes-Benz radar (how to turn on Mercedes-Benz GLC260 radar).

The detection range of Mercedes-Benz GLE radar is the full name of reversing radar, also known as "reversing anti-collision radar", also known as "parking assist device", which is a safety auxiliary device used for parking or reversing, which is composed of ultrasonic sensors, controllers and displays.

The reversing radar is designed and developed based on the principle that bats fly at high speed in the dark and do not collide with any obstacles.

The reversing sensor is a safety aid when the car is parked or reversing. It can tell the driver the surrounding obstacles through sound or more intuitive display, alleviate the trouble caused by the visit of the front, rear, left and right directions when the driver stops, reverses and starts the car, and helps the driver eliminate the defects of blindness and blurred vision, thereby improving driving safety. The car is equipped with a reversing radar.

When you are reversing, the radar will automatically turn on. If there is an obstacle in the rear of the car, the car's radar will sound an alarm, and the closer you get to the object, the faster the sound. The probe is mounted on the rear bumper.

Depending on the ** and brand, there are two, three, four, six, and eight probes, in the front, back, left, and right. The detector radiates at an angle of 45 degrees, searching for targets up and down, left and right. Its biggest advantage is that it can find obstacles that are below the bumper and difficult for the driver to see from the rear window, and call the police, such as flower beds, children squatting behind the car, etc.

The display of the reversing sensor is mounted on the rearview mirror. It constantly reminds the driver how far away the car is from the objects behind it. When the dangerous distance is reached, the buzzer starts beeping to stop the car.

When the gear lever is engaged in reverse gear, the reversing radar automatically starts working.
