When reversing, the reversing radar uses the ultrasonic principle, and the probe installed on the bumper at the rear of the car emits ultrasonic waves, and then reflects sound waves, thus calculating the actual distance between the car body and obstacles, and then prompting the driver to make parking or reversing easier and safer.
The car reversing radar keeps warning, so it is necessary to check whether there are obstacles. If there is no obstacle, it keeps ringing, and the sensor of the reversing radar may be dirty, so just wipe it clean. In addition, there may be a short circuit of the reversing radar alarm or a fault of the reversing radar sensor or controller, which needs to be repaired in the 4S shop.
Main functions:
(1) Accurately measure the distance from the rear of the vehicle to the nearest obstacle.
(2) When reversing to the limit distance, it can give a rapid alarm to remind the driver to pay attention to braking.
(3) It can repeatedly send out voice warning sounds to remind pedestrians to pay attention.
