The invention discloses a vehicle deviation compensation method and device based on an electric steering system, and the method and device are applied to a deviation compensation module of a vehicle, and the method comprises the steps: obtaining the state information of the vehicle in the driving process of the vehicle; according to the vehicle state information, determining a target state bit where the deviation compensation module is located, and controlling the vehicle to enter the target state bit; when the steering wheel is held for a long time, torque compensation is conducted according to the rack force learned through long-time rack force compensation; when in the activated state position, the torque compensation is performed after the short-time compensation rack force and the long-time compensation rack force of the vehicle are superposed; when in the waiting state position, torque compensation is carried out according to the rack force learned by long-time rack force compensation; and when in the exit state position, the motor torque of the deviation compensation module is reduced until the final output is zero. The problem that in the prior art, when a vehicle deviates, a steering wheel needs to be held by hand for a long time, fatigue is prone to occurring, and driving safety is low is solved.
本发明公开了一种基于电动转向系统的车辆跑偏补偿方法及装置,应用于车辆的跑偏补偿模块当中,该方法包括:在车辆行驶过程当中,获取车辆的状态信息;根据车辆状态信息确定跑偏补偿模块所处的目标状态位,并控制车辆进入目标状态位当中;当处于长时间手握方向盘状态位,按照长时补偿齿条力学习到的齿条力进行扭矩补偿;当处于激活状态位,对车辆的短时补偿齿条力、长时补偿齿条力叠加后进行扭矩补偿;当处于等待状态位,按照长时补偿齿条力学习到的齿条力进行扭矩补偿;当处于退出状态位,对跑偏补偿模块的电机扭矩下降,直至最终输出为零。本发明解决了现有技术中在面对车辆跑偏需要长时间手持方向盘而容易疲劳,导致行车安全性低的问题。
