Abstract (en)
[origin: WO2019137658A1] The invention relates to a method for determining the current lane roughness in a vehicle, in which the frequency-dependent amplitude response is determined from the wheel speed, and a roughness characteristic is determined as a measure of the roughness of the lane.
