The invention discloses a wheel relative rolling radius self-learning method and device, electronic equipment and a storage medium, and the method comprises the steps: starting the wheel relative rolling radius self-learning when the enabling condition of the wheel relative rolling radius self-learning is satisfied, marking the rolling radius of a preset wheel and recording the rotating circle number parameter of the preset wheel; according to the rolling radius and the rotating circle number parameter, the relative rolling radius of the preset wheel is obtained; and replacing a pre-stored rolling radius of the preset wheel with the relative rolling radius of the preset wheel to serve as a self-learning result of the relative rolling radius of the wheel. According to the method and the device, the calculation precision of the slip rate and the slip ratio is improved, improper (advanced or delayed) activation of the ABS, the DTC and the ARS is avoided, and the safety of the vehicle is ensured.
