The invention provides a torque distribution method, device and equipment and a storage medium, and the method comprises the steps: determining the current whole vehicle slip state of an automobile when the current slip of the automobile is judged, and calculating the original front axle torque distribution coefficient and the original rear axle torque distribution coefficient of the automobile; then the original front axle torque distribution coefficient and the original rear axle torque distribution coefficient are corrected according to the slip state of the whole vehicle, and the corrected front axle torque distribution coefficient and the corrected rear axle torque distribution coefficient are obtained; and based on the corrected front axle torque distribution coefficient and the corrected rear axle torque distribution coefficient, the output torque of the front axle and the output torque of the rear axle of the automobile are distributed, and the slip state is arranged to reflect the adhesion condition of tires and the ground. The original front axle torque distribution coefficient and the original rear axle torque distribution coefficient are corrected on the basis of the current whole vehicle slip state of the vehicle, torque distribution can be more reasonably carried out by fully utilizing the adhesive force between tires and the ground, and the escape capacity of the whole vehicle is improved.
本申请提供一种扭矩分配方法、装置、设备及存储介质,通过在判断汽车当前出现滑转时,确定汽车当前的整车滑转状态,并计算汽车的原始前轴扭矩分配系数和原始后轴扭矩分配系数,然后根据整车滑转状态对原始前轴扭矩分配系数和原始后轴扭矩分配系数进行修正处理,得到修正后的前轴扭矩分配系数和修正后的后轴扭矩分配系数,基于修正后的前轴扭矩分配系数和修正后的后轴扭矩分配系数分别对汽车的前轴和后轴的输出扭矩进行分配,整理滑转状态反映了轮胎与地面的附着力情况,基于汽车当前的整车滑转状态对原始前轴扭矩分配系数和原始后轴扭矩分配系数进行修正处理,可以充分利用轮胎与地面的附着力更合理的进行扭矩分配,提升整车的脱困能力。
