Abstract

A method for operating a motor vehicle with a chassis having a suspension device and a damping device according to which, for greater safety, the suspension and/or damping device is stiffened and/or blocked at least for individual wheels when an acceleration signal is applied. The invention also relates to a device with a construction for carrying out the method. The damping device is configured by a hydraulic shock-absorber for each wheel of the motor and at least one shock-absorber can be hydraulically stiffened or blocked via electronically controlled valves. The valve can be controlled by means of a control device connected to at least one acceleration sensor.
