The invention discloses a control method and device for preventing data abnormity of an electric power steering machine controller, and belongs to the technical field of vehicle control. The method comprises the steps of dividing the electric power steering machine controller into sub-function modules according to functions, setting a plurality of key thresholds for each sub-function module according to the function of each sub-function module; performing data monitoring on the sub-function modules of which the corresponding functions are started, and judging whether the sub-function modules of which the data are abnormal exist in combination with multiple key thresholds corresponding to the sub-function modules; and if the sub-function module of which the data is abnormal exists, determining the abnormal level of the abnormal sub-function module, and carrying out degradation processing on the abnormal sub-function module according to the function or performance pointed by the abnormal level. According to the method, when one or more functions are abnormal, data exception control, backup and degradation mode optimization management are carried out.
本发明公开了一种防止电动助力转向机控制器数据异常的控制方法及装置,属于车辆控制技术领域,其中,方法的实现包括:将电动助力转向机控制器按照功能分为各子功能模块,并根据各子功能模块的功能分别为各子功能模块设置多项关键阈值;对已经开启相应功能的子功能模块进行数据监控,结合子功能模块对应的多项关键阈值判断是否存在数据发生异常的子功能模块;若存在数据发生异常的子功能模块,则确定发生异常的子功能模块的异常级别,并对发生异常的子功能模块按照异常级别指向的功能或性能降级处理。通过本发明在单一或多个功能出现异常时,进行数据异常控制、备份及降级模式优化管理。
