introduction: Car body height sensor, also known as headlight level sensor. Mainly used to adjust the horizontal state of car headlights, a car has at least two body height sensors, one mounted on the front axle of the car and one mounted on the rear axle of the car.
The main working principle:
During the driving process, due to the uneven road surface, uphill and downhill, etc., the car will be high and low with the road surface, which will cause the headlights on the front of the car to be high and low, affecting the driver to see while driving. Unclear road conditions. So there is a body height sensor.
The body height sensor is currently mainly a Hall chip type measuring angle.
When the car is driving, because the sensor is installed on the rear axle of the front axle of the car, the angle between the car body and the ground is checked in real time, and the signal of the car body height sensor is timely fed back to the car control system. The control system is compared by data analysis, and then the command is issued. The headlight adjustment system is implemented to achieve a better and more effective illumination of the road ahead. Ensure driving safety.
