What Causes the Reversing Radar to Have No Sound Alert?

[VanAubree]

Reversing radar not producing sound alerts is due to a malfunction in the buzzer. Here is the relevant information: Principle of the reversing radar: The reversing radar emits ultrasonic waves through ultrasonic sensors, and these waves reflect back after hitting an obstacle, which are then received by the ultrasonic sensors. The controller calculates the distance to the obstacle based on the time taken for the ultrasonic waves to be emitted and returned, finally alerting the driver through rapid warning sounds from the buzzer. Main functions of the reversing radar: Accurately measures the distance between the rear of the vehicle and the nearest obstacle; emits rapid warning sounds when reversing to the limit distance to alert the driver to brake; repeatedly emits voice warnings to alert pedestrians.
