The ultrasonic sensor measures the distance between the vehicle and the obstacle in front by emitting ultrasonic signals and receiving echoes. When the controller control and process the echo signal, the direction and distance of the obstacle are determined. Finally, the display or buzzer issues an image prompt, allowing the driver to be aware of the situation when reversing, making it easier and safer.
Responsive, stable and durable.
By emitting ultrasonic signals and receiving echoes, thereby realizing the distance control and automatic parking functions
