Method and device for detecting a rough road section

摘要

A method for detecting a rough road section in a vehicle route comprises the following steps: sensing the acceleration of the vehicle with an acceleration sensor, evaluating the acceleration at several points of time, and detecting the rough road section with regard to the evaluation results. A device for detecting a rough road section in a vehicle route comprises an acceleration sensor for sensing the acceleration of a vehicle, an evaluation device for evaluating the acceleration at several points of time, and a detection device for detecting the rough road section with regard to the evaluation results. A speed control method according to the present invention comprises the following steps: detecting a rough road section, and fixing a nominal speed in response to the detection. A speed control system includes a rough road detection device and a speed controller which controls the speed of the vehicle according to the rough road detection.
