Detection of short term irregularities on road surface

The invention relates to detection of short term irregularities on a road surface. A method for providing information about road surface conditions, in particular road surface irregularities, under adriving vehicle having at least a first wheel, the method comprising: a) determining, with a wheel speed sensor, a wheel speed signal indicative of oscillations at the first wheel; b) determining an acceleration sensor signal indicative of a temporal movement of a vehicle chassis using one or more accelerometers in the vehicle, and c) determining a road surface condition, in particular a road surface irregularity, under the driving vehicle based on the wheel speed signal and the acceleration sensor signal. 本发明涉及路面上的短期不平度的检测。一种用于提供关于具有至少第一车轮的驾驶车辆下的路面状况、尤其是路面不平度的信息的方法，所述方法包括：a)利用轮速传感器，确定指示在所述第一车轮处的振荡的轮速信号；b)利用所述车辆中的一个或多个加速计，确定指示车辆底盘的依时间运动的加速传感器信号；以及c)基于所述轮速信号和所述加速传感器信号，确定所述驾驶车辆下的路面状况、尤其是路面不平度。
