[0002] CDC shock absorbers are a type of active suspension system that can adjust the strength of suspension damping in real time according to the driving state of the vehicle body. The biggest benefit of having CDC shock absorbers is to balance the contradiction between the softness and hardness of the suspension. CDC shock absorbers can not only improve comfort, but also be a safety feature. With CDC shock absorbers, the car can control roll, pitch, yaw and body more quickly and accurately, the stability of the car at high speeds and cornering is improved, and the body roll is reduced. The body leans forward less during braking, and starting and rapid acceleration can reduce the backward lean.
