The invention relates to the technical field of automobile electric power steering systems, and discloses a zero-position self-calibration control method, equipment and device for a steering wheel, and a storage medium. The method comprises the steps of acquiring preset feature information of a target vehicle; judging whether the target vehicle is in a straight running state or not according to the preset feature information; when the target vehicle is in a straight running state, acquiring a current corner value collected by a corner sensor arranged on the target vehicle; and setting the current corner value to a zero position through self-calibration, thereby realizing active alignment of an EPS system. By replacing manual calibration of a steering zero position with specific calibrationsoftware, the purpose of improving the efficiency of zero position calibration of the EPS system is achieved.

    本发明涉及汽车电动助力转向系统技术领域,公开了一种转向盘零位自标定控制方法、设备、存储介质及装置。本发明通过获取目标车辆的预设特征信息;根据所述预设特征信息判断所述目标车辆是否处于直行状态;在所述目标车辆处于直行状态时,获取置于所述目标车辆上转角传感器采集的当前转角值;将所述当前转角值自标定置零位,从而实现EPS系统的主动回正,替代通过特定的标定软件进行转向零位人工标定,达到提高EPS系统零位标定的效率。
