摘　　要：在永磁电机驱动的电动助力转向系统(EPS)中,电机位置传感器的信号质量直接关系到EPS的安全性和可靠性。文章在分析Hall式位置传感器的信号特征的基础上,通过设计角度计数器,提出了传感器信号的故障诊断策略,并在台架和整车上进行了试验验证。In the permanent magnet synchronous motor （PMSM） drove electrical power steering system （ EPS）, the signal quality of motor position sensor is very important which is relevant to the security and reliability of the EPS. This paper analyzes the characteristics of the signals produced by Hall sensor, by designing the angle counter, the fault diagnosis of EPS motor position sensor is bronght forward, which has been testified on test bench and vehicle road test.
