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.
