A Preconditioning Algorithm of Singular Point Rejecting for Wheel Speed Signal Processing in Anti-lock Brake System

分析ABS轮速信号处理中常见的虚假信号的产生原因和特点 ,运用时间序列分析的方法构造分离虚假信号的异点剔除预处理算法。对ABS实验数据的处理结果表明 ,该算法具有实时性好、虚假信号分离彻底的优点。

The cause and property of the common false wheel signal in anti-lock brake system has been studied in this paper. Based on the method of time series analysis, a kind of preconditioning algorithm of singular point rejecting has been devised in order to separate the false wheel speed signal. The corresponding processing on the experiment data shows that the preconditioning algorithm has the advantage of strong real-time property and can separate the false signal completely.
