摘　　要：提出了一种汽车ABS试验轮速信号异常值识别和处理的方法,剔除轮速信号中异常数据。基于Hampel识别器识别异常点,将异常信号点进行剔除,并采用最小二乘法对剔除点进行插值,有效的除去轮速信号中的干扰,最后用试验验证了该方法能有效地除去轮速信号异常值。A method for identifying and processing the abnormal value of the wheel speed signal of the automobile ABS test is proposed,and the abnormal data in the wheel speed signal is eliminated.The abnormal points are identified and removed based on Hampel identifier.The least square method is used to interpolate the culling points,and the interference in the wheel speed signal are effectively removed.Finally,the experiment verifies that the method can effectively remove the abnormal value of the wheel speed signal.
