摘　　要：为确保加速踏板信号的可靠性,采用非接触式霍尔传感器作为电子加速踏板位置传感器,对踏板位置传感器信号提出一种改进的一阶低通滤波算法,进行2次滤波消除信号突变,并结合电动汽车电机驱动特性对加速踏板位置传感器信号进行故障诊断.通过建立踏板信号控制模型仿真,测试了整个控制过程的可靠性.结果表明,踏板信号出现毛刺及过高、过低或同步误差较大等异常时能准确判断出各种故障状态,该控制方式可满足纯电动汽车电子加速踏板可靠性控制的要求.In order to ensure the reliability of the accelerator pedal signal, non-contact Hall sensor was adopted as an electronic accelerator pedal position sensor. In order to ensure the acceleration pedal signal reliability with a non-contact Hall sensor as the electronic accelerator pedal position sensor and the pedal position sensor signal, an improved first-order low-pass filtering algorithm was proposed and combined with the motor driving characteristics of the accelerator pedal position sensor signal fault diagnosis. Through the establishment of the pedal signal control simulation model, the reliability of the whole control process was tested. The results have shown that pedal signal glitches, too high, too low or synchronous error can accurately identify various fault conditions. This control method can meet the reliability control requirements of pure electric automobile electronic acceleration pedal.
