The invention relates to the field of automobile control, and provides a deviation compensation method of an electric power steering system, which comprises the following steps: determining a quasi-compensation current of a power-assisted motor based on a rack force required to be compensated, and correcting the quasi-compensation current to obtain an actual compensation current, the correction is related to a historical sequence of the actual compensation current. Meanwhile, the invention further provides an electric power steering system and a vehicle comprising the electric power steering system. According to the implementation mode provided by the invention, the applicability of an electric power steering system product and the driving experience of a driver are improved.

    本发明涉及汽车控制领域,其实施方式提供了一种电动助力转向系统的跑偏补偿方法,包括:基于所需补偿的齿条力确定助力电机的拟补偿电流,所述跑偏补偿方法还包括:对所述拟补偿电流进行修正后得到实际补偿电流,所述修正与所述实际补偿电流的历史序列相关。同时还提供了一种电动助力转向系统,以及包含该电动助力转向系统的车辆。本发明提供的实施方式提升了电动助力转向系统产品的适用性和驾驶员的驾驶体验。
