Abstract

A method is provided for operating an active chassis system, in which wheels of at least one axle are arranged with a toe-in angle, and actuating elements which interact with supporting assemblies which are arranged between the wheels and a vehicle body. Wheel contact forces of the wheels assume different values as a result of the actuating elements being actuated. A side force is generated at the wheels which have a toe-in angle, and a resulting yaw moment is produced. A desired yaw rate is determined based upon information from a device which is arranged in the vehicle in order to determine the profile of the roadway in a control unit, and the wheel contact forces are set as a function of the desired yaw rate.
