The invention discloses a vehicle control method and system, a vehicle and a readable storage medium, and the method comprises the steps: determining the torque reduction torque of a slipping wheel when the vehicle is in a differential steering working condition and the vehicle has the slipping wheel; and the torque of the coaxial wheels is adjusted according to the torque reduction torque. According to the method, when the vehicle is determined to be in the differential steering working condition, the differential state of the vehicle is classified, the wheel slipping problem under the differential working condition is subjected to identification scheme optimization, and different driving torque control logics are used, for example, a coaxial control strategy is adopted for slipping wheels, so that the wheel slipping problem is solved. A control strategy is formulated according to the working condition of reverse slipping of the wheels on the inner side, it is guaranteed that reverse slipping of the wheels can be recognized in time, the use scene of the differential function is expanded, the phenomena of high-speed slipping of the wheels, posture deflection of a vehicle body and the like of the vehicle are avoided, and the reliability of the differential function of the vehicle is improved.
本发明公开了一种车辆控制方法、控制系统、车辆及可读存储介质,该方法包括:当车辆处于差动转向工况,且车辆存在打滑的车轮时,确定打滑车轮的降扭扭矩;根据降扭扭矩对同轴车轮进行扭矩调节。本发明在确定车辆处于差动转向工况下,通过对车辆差动状态的分类,对差动工况下的车轮打滑问题进行了识别方案优化,并使用不同的驱动扭矩控制逻辑,如针对打滑车轮采用同轴控制策略,又针对内侧车轮反向打滑的工况制定了控制策略,既保证车轮出现反向打滑时可及时识别,也拓展了差动功能的使用场景,避免车辆出现车轮高速打滑及车身姿态偏转等现象,提升了车辆差动功能的可靠性。
