Extended data:
Generally speaking, vehicles equipped with air-type adjustable suspension have ground distance sensors near the front and rear wheels. The driving computer will judge the height change of the car body according to the output signal of the ground distance sensor, and then control the air compressor and exhaust valve to make the spring automatically compress or stretch, thus reducing or increasing the ground clearance of the chassis, and increasing the stability of the high-speed car body or the passability of complex road conditions. In daily adjustment, the air suspension will have three states.
