Abstract: A method for operating a motor vehicle having an active roll control and an active steering system designed to map a steering-wheel setting angle predetermined by a driver of the motor vehicle in accordance with a predetermined steer response onto a steer angle of the motor vehicle. The method includes operating the active steering system in a normal operating mode having a normal steer response and upon determining an active roll control fault operating the active steering system in a fallback operating mode in accordance with an fallback steer response, the fallback steer response different from the normal steer response.

Abstract: A compensating method is provided for avoiding a bouncing movement of a wheel of a motor vehicle. The motor vehicle comprises an unsprung mass (m) that is attached in a movable manner to a sprung mass, wherein the unsprung mass (m) comprises the wheel, and an actuator that is embodied so as to apply a force (K) between the sprung mass and the unsprung mass (m). During a movement of the unsprung mass (m) relative to the sprung mass in an application of force by means of the open loop control of the actuator by the method, a force (K) is applied between the sprung mass and the unsprung mass (m) so as to damp the movement. A motor vehicle implementing the method is also provided.

Abstract: An adjustment system and method for adjusting a chassis property of a motor vehicle wherein an understeering sensitivity of the motor vehicle is increased upon detecting that a trailer has been coupled to the motor vehicle. A detection unit operates to detect when a trailer is attached or coupled to the motor vehicle.

Abstract: A system and method for operating a motor vehicle having an active roll control system and an air suspension system including operating the air suspension system in a normal mode, according to a normal air spring setting. Upon determining a fault or malfunction of the active roll control system operating the air suspension in a fallback mode, according to a fallback air spring setting, wherein the fallback mode is different from the normal mode.

Abstract: A wheel suspension unit is disclosed. The wheel suspension unit includes a stabilizer having a first end and a second end, a wheel suspension element, and a piston-cylinder unit. The piston-cylinder unit connects an end of the stabilizer to the wheel suspension element. The piston-cylinder unit is a roll damper. The roll damper includes a plurality of roll damping valves arranged in a piston of the roll damper. Each of the plurality of roll damping valves has a non-return valve and an adjustable throttle valve. The non-return valve is arranged in series with the adjustable throttle valve.
