The invention provides a driving wheel rotating speed correction method and system and a vehicle, and belongs to the technical field of vehicles, and the driving wheel rotating speed correction method comprises the steps that the actual rotating speeds of a plurality of driving wheels are obtained in response to the condition that the working condition of the vehicle meets a preset condition; based on the actual rotating speed and the preset wheel diameter, the presumed vehicle speed corresponding to each driving wheel is determined; determining a reference vehicle speed of the vehicle based on the estimated vehicle speed or an output rotational speed of a power source of the vehicle; and correcting the current actual rotating speed of each driving wheel based on the difference between the estimated vehicle speed and the reference vehicle speed. The wheel speed difference between the driving wheels is eliminated, and the problems that the function triggering opportunity of an active safety system is judged mistakenly, the gear shifting opportunity is judged mistakenly, and the wheels are abraded abnormally are solved.
本申请提供了一种驱动轮转速修正方法、系统及车辆,属于车辆技术领域,驱动轮转速修正方法包括:响应于车辆的工况满足预设条件,获取多个所述驱动轮各自的实际转速;基于所述实际转速与预设轮径,确定每一所述驱动轮分别对应的推定车速;基于所述推定车速或所述车辆的动力源的输出转速,确定所述车辆的参考车速;基于所述推定车速与所述参考车速之间的差距,对每一所述驱动轮的当前实际转速进行修正。本申请消除了各个驱动轮之间的轮速差,避免了主动安全系统功能触发时机判定失误、换挡时机判定失误,以及车轮异常磨损等问题的发生。
