The embodiment of the invention provides an EPS lane keeping control method and device based on four-wheel steering, and relates to the technical field of vehicle control. The method comprises the following steps: acquiring a corner request signal; judging a size relationship between a request corner in the corner request signal and a preset request corner threshold value to obtain a judgment result; and determining the direction of the rear wheel compensation torque in rear wheel steering according to the judgment result. According to the embodiment of the invention, the safety and stability when the four-wheel power-assisted steering system controls the vehicle to keep the lane are improved.

    本申请实施例提供了一种基于四轮转向的EPS车道保持控制方法及装置,涉及车辆控制技术领域。其中方法包括:获取转角请求信号;判断所述转角请求信号中的请求转角与预设请求转角阈值之间的大小关系,得到判断结果;根据所述判断结果确定后轮转向中的后轮补偿力矩的方向。本申请实施方式提升了四轮助力转向系统控制车辆车道保持时的安全性与稳定性。
