Abstract

For dampening vibrations in the drive system of a vehicle which is equipped with a control system (an anti-lock system, traction slip control system, etc.), torsional vibrations in the circumferential direction of the wheels are determined by evaluating the rotational behavior of the individual wheels. The torsional vibrations are dampened as a function of the amplitude and the phase positioning of the torsional vibrations by introducing braking pressure or by modulating the braking pressure introduced into the wheel brakes of the individual wheels for slip control.
