Abstract
An active suspension for a driver seat of a bus or a heavy vehicle which comprises an electric actuator allowing the exertion of the force between the floor of the vehicle and the bottom of the seat. The adjustment of the height of the seat is accomplished by an electric actuator or by an independent mechanical system. A controller generates a control force calculated from measurements obtained by sensors located at different locations on the suspension. Forces exerted by the electric actuator can be relieved by passive element placed in parallel which cannot assume by themselves the role of a suspension for a given application.
