The invention discloses an automobile suspension continuously adjustable damping control system which comprises a CDC ECU, suspension height sensors, IMU sensors and CDC shock absorbers, the number of the suspension height sensors and the number of the CDC shock absorbers are both four, and the suspension height sensors, the IMU sensors and the CDC shock absorbers are all connected with the CDC ECU. According to the invention, four suspension height sensors and one IMU sensor are used, on one hand, the number of the sensors is reduced, the computing power requirement of an ECU is reduced, and thus the system cost is reduced, and on the other hand, the IMU sensor is used for directly measuring the posture of a vehicle body, and the suspension height sensors are used for directly measuring the height of the suspension so as to obtain the actual signal of the stroke of the shock absorber. Damping adjustment of the shock absorber is more accurate, and the effect of improving comfort, stability and controllability of vehicle driving is better.

    本发明公开了一种汽车悬架连续可调阻尼控制系统,包括CDC ECU、悬架高度传感器、IMU传感器和CDC减震器,所述悬架高度传感器和CDC减震器均设置有四个,所述悬架高度传感器、IMU传感器和CDC减震器均与CDC ECU连接。本发明,使用4个悬架高度传感器和1个IMU传感器,一方面减少了传感器的数量、降低了ECU的算力要求,从而降低了系统成本,同时由于使用IMU传感器直接测量车身姿态、使用悬架高度传感器直接测量悬架高度进而得到减震器行程的实际信号,使得减震器阻尼调节更加精准,对车辆行驶的舒适性、稳定性和操控性的改善效果更佳。
