The invention relates to the technical field of steering wheel zero offset calibration, and discloses an AGV steering wheel zero offset calibration method and system, a vehicle and a medium, and the method comprises the steps: obtaining the steering wheel wheelbase of a target AGV, and the pose data and course angle of the target AGV when the target AGV moves to any moment; determining vehicle deviation data at the current moment based on the pose data and the course angle; determining steering wheel zero offset data at the current moment based on a preset steering wheel model, the pose data and the steering wheel wheelbase; and calibrating the target AGV based on the vehicle deviation data and the steering wheel zero deviation data. According to the method, research on the steering wheel zero offset of the three-steering-wheel AGV is considered, decoupling calibration is carried out on the steering wheel zero offset by utilizing the single-steering-wheel kinematics model, the calibration time of the steering wheel zero offset can be greatly shortened, the calibration precision and efficiency are improved, and automatic, efficient and accurate steering wheel zero offset calibration requirements are met.
