Résumé :
|
The present invention relates to an active seat suspension control system in a vehicle, comprising a vibrometer with a vertically movable mass, a vertically movable seat, transducers providing first ans second signals representing the vertical position of the mass and seat respectively, a comparator responsive to the two signals to provide an error signal, and an actuator coupled to the seat and responsive to the error signal to move the seat so that the seat tends to follow the vertical movements of the mass. Such a system can be used to effect movement of the seat of an agricultural tractor or similar vehicle to cushion the operator from shocks and other undesired motions.
