ABSTRACT:
The present invention is adapted to control the motion of a seat 102 located in a seat suspension system 100. The present invention determines a total damping force based on an absolute velocity damping force and a relative velocity damping force. Based on the absolute and relative damping force, a total damping force is determined which will provide a smooth ride for the operator throughout the range of travel of the seat, while prevention collisions with the end stops.
