The disclosure provides adjusting operational parameters based on identified roadway irregularities. Methods and systems are provided for improving vehicle speed measurements. A vehicle may detect the impact of a roadway irregularity to its front wheels and its rear wheels, and may calculate an instantaneous vehicle speed on the basis of its wheelbase and an elapsed time between the two impacts. This instantaneous vehicle speed may then be used to calculate one or more correction factors which may be used to correct a conventionally-acquired vehicle speed measurement, an operational parameter of the vehicle underlying such measurements (such as a wheel size or a final drive ratio), or both.

    本公开提供“基于所识别的道路不平整处调整操作参数”。提供了用于改善车辆速度测量值的方法和系统。车辆可检测道路不平整处对其前轮和后轮的撞击,并且可基于其轴距和所述两次撞击之间经过的时间来计算瞬时车辆速度。然后,可使用该瞬时车辆速度来计算一个或多个校正因素,所述校正因素可用于校正常规获取的车辆速度测量值、此类测量值所依据的所述车辆的操作参数(诸如车轮大小或主减速比)或两者。
