The invention provides a method for quickly detecting a wheel speed fault, which comprises the following steps of: 1, acquiring a signal of the same wheel through different wheel speed processing chips, and processing the signal; step 2, comparing the wheel speed signals of the same wheel, if there is a difference, reporting that the wheel speed signal verification is abnormal, and entering step 3; step 3, comparing the wheel speeds of different wheels with wheel speed verification abnormal faults, and screening out problem wheel speed signals; and 4, setting the problem wheel speed signal to be invalid, and ending the detection. The same wheel speed is detected through the two wheel speed processing chips, the same wheel speed signal is verified, and the detection is abnormal; and the abnormal wheel speed signal is compared with other wheel speed signals, a problem wheel speed signal is confirmed, the wheel speed signal is set to be an invalid value, detection is ended at the same time, the wheel speed fault is rapidly identified, the fault detection time is greatly shortened, and the fault detection efficiency is improved.

    本发明提供一种快速检测轮速故障的方法,包括以下步骤:步骤一,通过不同轮速处理芯片采集同一车轮信号,进行信号处理;步骤二,同一车轮轮速信号进行比较,存在差异,报出轮速信号校验异常,并进入步骤三;步骤三,不同车轮轮速与轮速校验异常故障进行对比,筛选出问题轮速信号;步骤四,将问题轮速信号置为无效,检测结束。通过2个轮速处理芯片对同一轮速进行检测,校验同一轮速信号,检验异常;再将异常轮速信号与其他轮速信号比对,确认问题轮速信号,将该轮速信号置成无效值同时结束检测,快速识别轮速故障,大大缩短了故障检测时间,提高了故障检测效率。
