The embodiment of the invention relates to an EPS control method and device based on deviation compensation. The control method comprises the steps that current driving information of a vehicle is obtained in real time; wherein the driving information at least comprises a steering wheel rotating angle, a steering wheel rotating speed, input hand power and a vehicle speed of the vehicle; determining a current compensation value based on whether the current driving information meets a first preset condition; wherein the current compensation value is determined in real time according to the rack force of the vehicle under the condition that the current driving information meets the first preset condition, and the current compensation value is determined according to the compensation value of the vehicle in the previous state meeting the first preset condition under the condition that the current driving information does not meet the first preset condition; and in response to the fact that the current driving information meets the second preset condition, the EPS is controlled to execute the compensation action according to the current compensation value, all working conditions in the whole driving process of the vehicle are covered by determining the process of the current compensation value, and the problem that the vehicle is prone to quit in the deviation compensation process is effectively avoided.

    本申请实施例涉及一种基于跑偏补偿的EPS控制方法及控制装置,控制方法包括:实时获取车辆的当前行驶信息;其中,行驶信息至少包括车辆的方向盘转角、方向盘转速、输入手力和车速;基于当前行驶信息是否满足第一预设条件,确定当前补偿值;其中,在当前行驶信息满足第一预设条件的情况下,当前补偿值是实时根据车辆的齿条力确定的,在当前行驶信息不满足第一预设条件的情况下,当前补偿值是根据车辆在上一满足第一预设条件的状态下的补偿值确定的;响应于当前行驶信息满足第二预设条件,控制EPS根据当前补偿值执行补偿动作,通过确定当前补偿值的进程覆盖了车辆整个行进过程中的所有工况,并且有效避免车辆出现跑偏补偿的过程容易退出的问题。
