Control of damper friction effects in suspension

摘要

In some examples, the vehicle suspension for at least partially supporting the spring supermass includes a damper connected to the spring supermass, and the damper includes a movable piston. The vehicle suspension further includes an actuator and a controller. The controller can be configured to determine the frequency of motion associated with the spring supermass. When the frequency of motion is less than the first frequency threshold, the controller can send a control signal to cause the actuator to apply the deceleration force to the spring supermass. Further, when the frequency of motion associated with the spring supermass exceeds the first frequency threshold, the controller can send a control signal to cause the actuator to apply the compensating force to the spring supermass. For example, the magnitude of the compensation force can be based on the frictional force determined for the damper.
