ABS轮速信号的采集方法研究

Research on the Acquisition of ABS Wheel Speed Signal

在分析现有轮速信号采集方法的基础上,提出了一种能够将精度和实时性相结合的速度测量方法——自适应的轮速信号采集方法,该方法可根据轮速大小采用变化的采样周期采集轮速信号。通过仿真和路试结果表明,该自适应轮速信号采集方法在全车速范围内均能满足采集精度与实时性要求。

Based on the analysis of the existing wheel speed acquisition method,adaptive wheel speed acquisition method is put forward,a vehicle speed measurement method which can combine the precision and real-time.The method can collect wheel speed signal with variable sampling period according to wheel speed.The results of simulation and road test show that the adaptive wheel speed signal acquisition method can satisfy the requirement of sampling precision and real-time in the whole range of vehicle speed.
