Working Principle and Main Functions of Reversing Radar
When reversing the car, the radar uses the principle of ultrasound to transmit the sound wave from the probe installed on the rear bumper after it strikes the obstacle, calculates the actual distance between the car body and the obstacle, and then prompts the driver to make parking or reversing easier and safer.
(1) Measure the distance between the rear end and the nearest obstacle accurately;
(2) When backing up to the limit distance, the driver can be warned to pay attention to braking by a rapid warning sound.
(3) Repeated voice warning can be issued to remind pedestrians to pay attention.
