Abstract
An active chassis in a motor vehicle has a controllable suspension system which includes passive spring elements between a wheel of the vehicle and a body of the vehicle as well as supporting units which are provided for the spring elements and can be adjusted by a control signal. Transducers are provided for the supporting units to detect state variables of the supporting units. In addition, a control unit is provided to generate the control signal from a setpoint signal which can be preselected via an input element and an actual signal which is determined from the detected state variables. To provide an easily implemented method of controlling the roll moment distribution between front and rear axles of the vehicle, the roll moment distribution to be set between the front and rear axles of the vehicle can be preselected as the setpoint signal in the input element. In addition, an actual signal representing the actual roll moment distribution can be determined in the control unit as a function of the state variables of the supporting units.
