Abstract: A device for operating a chassis of a two-track vehicle, in which each vehicle wheel is assigned a suspension spring, which carries the static body weight of the vehicle, and a vertical dynamics actuator, which is actuatable by a vertical dynamics control unit, having a tipping detection function which detects a tipping situation with a roll-over risk in which there is a danger that the vehicle will tip sideways on a transversely inclined roadway. When a roll-over risk is detected, the vertical dynamics control unit actuates the vertical dynamics actuators to avoid roll-over.

Abstract: A vehicle with an active chassis, in which each vehicle wheel is linked to the vehicle body by a wheel suspension which has a vibration/damping device with a vertical dynamics system which can be controlled by a chassis control unit, namely by adjusting the roll stiffness and the articulation capability of the vehicle which behaves in the opposite direction. The chassis control unit is assigned a user-operable input with which the roll stiffness and the opposing articulation capability can be manually adjusted, in particular during off-road driving.

Abstract: A parking brake system for a vehicle, in particular for a motor vehicle, includes two control units, by means of which two actuators, which are designed to actuate respective wheel brakes, can be controlled. The control units are connected to a power source via separate lines, wherein exclusively one of the control units is connected to an operating device which is designed to transmit signals to the control unit for actuation of the wheel brakes. The control unit is designed to control at least one of the actuators, dependent on the signals for actuation of the wheel brakes.
