The invention discloses a control method for restraining deviation of an automobile based on electric steering, belongs to the technical field of automobiles, and particularly relates to a control method for restraining running deviation of the automobile by actively applying steering torque control to the automobile when an electric steering system recognizes that the automobile has a deviation trend. According to the method, a series of signals representing the automobile driving posture on the CAN bus are monitored through the automobile EPS to recognize and judge the deviation trend of the automobile, and different steering compensation moments are actively applied according to the deviation trends of different degrees, so that the purpose of restraining the deviation of the automobile is achieved. The method has the beneficial effects that the deviation trend of the automobile can be automatically recognized, the compensation torque is actively applied, the deviation phenomenon is weakened, automatic repair of automobile faults is completed when a user does not perceive, and complaints of the user are reduced; in the after-sales market, the measures of replacement of parts of the suspension system and four-wheel positioning are not needed, and cost, labor and time are saved.

    本发明公开了一种基于电动转向抑制汽车跑偏的控制方法,属于汽车技术领域,具体地说是电动转向系统识别到汽车有跑偏趋势时,对汽车主动施加转向力矩控制,达到抑制汽车行驶跑偏的一种控制方法。本发明利用汽车EPS监测CAN总线上的一系列表征汽车行驶姿态的信号,来识别判断汽车的跑偏趋势,并根据不同程度的跑偏趋势,主动施加不同的转向补偿力矩,从而实现抑制汽车跑偏的目的。本发明专利的有益效果为:能够自动识别汽车跑偏趋势,并主动施加补偿力矩,减弱跑偏现象,在用户无感知时完成车辆故障的自动修复,减小用户抱怨;在售后市场,不需要进行悬架系统零部件的更换以及四轮定位的措施,节省成本、人工和时间。
