Detection of road bumps using a situation analysis

摘要

The invention relates to a speed adjustment device (100) for a vehicle. This has a detector arrangement (110), which is designed to detect a vertical position change of a preceding vehicle, and a control device (120), wherein the vertical position change of the preceding vehicle is caused by a ridden road surface unevenness. The controller (120) is implemented when the vertical position change of the preceding vehicle exceeds a predefined threshold and occurs within a predefined period of time to infer significant roadway fuzziness and for this reason reduce the speed of the vehicle.
