The invention provides a steering wheel angle sensor fault detection method and device, and the method comprises the steps: obtaining a first steering wheel angle value and a second steering wheel angle value; determining a first parameter and a second parameter according to an angle measuring range corresponding to the steering wheel angle sensor, the first steering wheel angle value and the second steering wheel angle value; determining a target parameter according to the first parameter and the second parameter; and according to the target parameter and a preset angle difference threshold, judging whether the steering wheel angle sensor has a fault or not. The method is suitable for detecting the stroke boundary of the steering wheel angle sensor, so that the steering wheel angle sensor can be directly assembled in the assembly production and assembly link, whether the position near the zero angle of the steering wheel angle sensor corresponds to the stroke middle position of the rack or not does not need to be considered, and the assembly complexity is reduced.
本申请提供一种方向盘转角传感器故障检测方法及装置,其中,该方向盘转角传感器故障检测方法包括:获取第一方向盘角度值和第二方向盘角度值;根据方向盘转角传感器对应的角度量程、第一方向盘角度值和第二方向盘角度值,确定第一参数和第二参数;根据第一参数和第二参数,确定目标参数;根据目标参数和预设角度差阈值,判断方向盘转角传感器是否存在故障。本申请适用于方向盘转角传感器的检测行程边界,从而可以在总成生产装配环节直接进行装配,无需考虑方向盘转角传感器的0角度附近位置是否对应于齿条的行程中间位置,降低了装配的复杂性。
