What is the Function of an Automotive Air Suspension System?
1 Answers
Introduction to the functions of an automotive air suspension system: 1. Control the damping force of the shock absorber: The air suspension system collects signals from sensors such as the vehicle speed sensor, steering angle sensor, and body height sensor. After processing by the suspension ECU, it controls electromagnetic or stepper motor actuators to adjust the damping force of the shock absorber. During sharp turns, rapid acceleration, or emergency braking, it suppresses vehicle "squat," "dive," and roll, preventing excessive changes in vehicle posture, thereby improving handling stability. 2. Adjust the stiffness of the elastic element: The air suspension system adjusts the stiffness of the shock absorber by changing its elastic coefficient, allowing the vehicle to freely choose between sport mode or comfort mode based on actual driving needs. 3. Adjust the vehicle height: One of the main functions of the air suspension system is to maintain the vehicle height within a reasonable range under various operating conditions. If the vehicle remains too high off the ground for an extended period, driving will feel very bumpy, as if no shock absorbers are installed. If the vehicle is too close to the ground, the lower part of the chassis may easily collide with uneven surfaces, or even render the vehicle undrivable. The electronically controlled air suspension system automatically compresses or extends the air springs by controlling the air compressor, height control valve, and exhaust valve, thereby reducing or increasing the ground clearance of the chassis to maintain the vehicle at an appropriate height.
