Abstract: Examples of techniques for classifying roughness of a road are disclosed. In one example implementation, a method includes performing a first temporal analysis based at least in part on a speed of each of a plurality of wheels of a vehicle. The method further includes performing a second temporal analysis based at least in part on a combined wheel speed of the plurality of wheels. The method further includes performing a frequency analysis based at least in part on the speed of each of the plurality of wheels of the vehicle. The method further includes classifying the roughness of the road based at least in part on the first temporal analysis, the second temporal analysis, and the frequency analysis.

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.

Abstract: A method is provided to control a power steering device and an adaptive damping system of a motor vehicle. The power steering device makes available a mechanical steering angle range that is limited by steering stops. The adaptive damping system makes available a variable damping force. The damping force of the adaptive damping system is increased and a maximum achievable steering angle is simultaneously increased in case a steering stop is reached.
