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.

    本申请公开了一种车轮相对滚动半径自学习方法、装置及电子设备、存储介质,其中所述方法包括:在满足车轮相对滚动半径自学习的使能条件时,启动所述车轮相对滚动半径自学习,标记预设车轮的滚动半径并记录所述预设车轮的旋转圈数参数;根据所述滚动半径以及所述旋转圈数参数,得到所述预设车轮的相对滚动半径;将所述预设车轮的相对滚动半径替换预先存储的预设车轮的滚动半径,作为车轮相对滚动半径自学习的结果。通过本申请提高了滑移率、滑转率的计算精度,避免了ABS、DTC、ARS的不当(提前或延后)激活,保证了车辆的安全性。
