The invention discloses a steering wheel zero-bias self-learning method, system and device and a computer medium, and relates to the technical field of vehicle driving, and the method comprises the steps: recording a state value of a steering wheel turning angle in response to a vehicle being in a stable and straight-going state; generating a state average value of the steering wheel angle according to the state value; updating corner statistical information based on the state average value, wherein the corner statistical information is used for recording distribution information of the corner average value in a set corner interval; based on the corner statistical information and the corner interval, obtaining a deviation value of the steering wheel corner; based on the deviation value and the historical zero offset value, a target zero offset value of the steering wheel is obtained, and the vehicle is managed and controlled based on the target zero offset value; wherein the distribution information comprises the number or duration of the corner average value in the corner interval; the historical zero offset value comprises the zero offset value of the steering wheel stored when the vehicle is powered off last time. The accuracy of the turning angle and the turning angle statistical information is ensured, the accuracy of the deviation value is improved, and the accurate identification of the zero offset of the steering wheel is realized.
