The main working principle of the body height sensor is to detect the change of the body height and convert it into an electrical signal input control device. Taking the photoelectric sensor as an example, the sensor shaft is fixed with a disk with many narrow slots, and the shutter is composed of a light-emitting diode and a photosensitive diode transistor. The rotation of the disc converts the output of the shutter to ON/OFF and transmits this signal through the signal line to the suspension electronic control device. When the height of the body changes, the disc is turned by the sensor shaft, so that the electronic control device detects the change in the height of the body
The body height sensor plays a crucial role in the automobile. It is responsible for monitoring the distance between the vehicle and the ground in real time, ensuring that the vehicle remains stable in all conditions. When the vehicle is driving in different road conditions, the sensor shaft will rotate with the movement of the suspension, so as to detect changes in the height of the body and ensure that the vehicle always maintains the best driving attitude
In addition, the body height sensor is also used to adjust the level of the headlights to ensure that the headlights can effectively illuminate the road ahead, improving driving safety
