The reasons for the radar not making sound in the Hongqi H5 are: 1. The power cable of the main unit is not properly connected, resulting in no current; 2. The radar main unit cable has become loose; 3. The radar buzzer is damaged; 4. The wiring at the bumper is damaged. The working principle of the radar is that during reversing, it uses ultrasonic waves emitted by a probe installed on the rear bumper to hit obstacles and reflect infrasound waves, calculating the actual distance between the vehicle body and the obstacle. The functions of the radar are: 1. Accurately measuring the distance between the rear of the vehicle and the obstacle; 2. Emitting an urgent warning sound when reversing to the limit distance to remind the driver to pay attention to braking; 3. Repeatedly emitting a voice warning sound to alert pedestrians.
