Abstract: The stiffness of dampers for wheels on the front and rear axles are selectively controlled with a control unit. The control unit is configured to detect if the vehicle travels in a curve. In the case of a tendency of the vehicle to understeer, the control unit adjusts the damper of the wheel of the front axle located on the curve outside harder than the damper of the wheel of the front axle located on the curve inside. In the case of a tendency of the vehicle to oversteer, the control unit adjusts the damper of the wheel of the front axle located on the curve inside harder than the damper of the wheel of the front axle located on the curve outside.

Abstract: A method for operating a motor vehicle having at least a first axle and at least a second axle, wherein the motor vehicle has a chassis that can be adjusted by the user, and which is operable at least in a first mode and at least in a second mode, which is more comfortable than the first mode. When the user activates the more comfortable second mode, a loading state of the motor vehicle is checked. The chassis is not shifted from the first mode into the second mode for at least axle, or is changed from the second mode into the first mode of the chassis if a limit load is exceeded.
