Abstract

A method for adjusting the spatial position of the roll axis of a motor vehicle includes: a) defining a desired spatial position of the roll axis; b) determining a transverse acceleration of the motor vehicle; c) defining a desired transverse tilt of the motor vehicle and determining a desired transverse offset of the motor vehicle as a function of the transverse acceleration, so that the roll axis is moved into the desired position when the desired transverse tilt and the desired transverse offset are adjusted; d) adjusting a first actuator of an active chassis system of the motor vehicle, so that the motor vehicle assumes the desired transverse tilt determined in step c); and adjusting a second actuator to influence the transverse movement of the motor vehicle, so that the motor vehicle assumes the desired transverse offset determined in step c).
