The process according to the invention allows the adjustment of different damping characteristics of a motor vehicle damper taking into account the state of travel of the motor vehicle and damping requirement defining quantities depending on the travelling state according to an operating mode which can be preselected by the driver. The switch takes place as a function of a value of the total damping requirement determined from the instantaneous values of the damping requirement defining quantities according to a power function. The damping characteristic which is most desirable at each moment in time can be defined in real time. The process according to the invention can be used for various vehicles owing to adaptation of parameters which determine the power function.

Process and arrangement for controlling a vibration damper

Assisted steering system for non-trackbound vehicle

For controlling a motor vehicle friction clutch (3) which is operated by an actuating drive (7) during parking maneuvers, an output adjusting device (19) of the internal combustion engine (1) is unaffected over a limited initial pedal travel (.alpha..sub.0) of the accelerator pedal (17). According to the pedal position at any given time, the actuating drive (7) of the clutch (3) is controlled within the initial pedal travel. According to the pedal position and in keeping with a predetermined first signal characteristic a desired torque signal is generated and the actuating drive (7) is positioned as a function of the desired torque signal and in keeping with a predetermined second signal characteristic. In the clutch position determined by the pedal position, an actual torque signal is generated which represents the torque of the internal combustion engine (1) and it is compared with the desired torque signal. If the torque signals deviate from each other, a predetermined and appropriately directed correction factor is added and the actuating drive (7) is subsequently controlled as a function of the altered second signal characteristic.
