Suspension system having active compensation for vibration

摘要

A suspension system for a seat of a vehicle comprises a base, a linkage, and a seat attached to the base via the linkage. A pneumatic shock absorber provides a respective resistance level against movement of the seat with respect to the base based on a corresponding pressure level of air or gas within the pneumatic shock absorber. A set of cylindrical members are spaced apart beneath the seat. A tension member is arranged to engage the cylindrical members. The tension member is attached to the seat via a bracket. An electric motor is capable of driving one of the cylindrical members. A first sensor is arranged to detect first sensor data associated with an instantaneous position of the seat versus time. A controller generates a first control signal for the electric motor to change a height of the seat in opposition to a change in the instantaneous position of the seat and a second control signal to change the pressure level.
