Abstract (en)

[origin: EP0921386A2] The shock absorber damping is derived from the force response of the vehicle to the vibration of a vibrator plate and the relative phase function between the force exerted by the plate and the movement of the plate. A signal representing the cycle of the power response at a target frequency is divided into a push step signal and a pull step signal. The two signal parts are then separately subjected to further processing. An Independent claim is provided for a device for carrying out the method.
