The invention discloses a vehicle front and rear axle torque control method, device and equipment and a readable storage medium, and the vehicle front and rear axle torque control method comprises the steps that the maximum torque boundary value of a vehicle front axle and a vehicle rear axle is determined according to the normal stress, the road adhesion coefficient and the maximum slip rate of each wheel of the vehicle; and when the rotating speed difference value of the vehicle front and rear shafts is larger than a preset difference value, the vehicle front and rear shafts are controlled to conduct torque transfer within the maximum torque boundary value range. According to the method, when the rotating speed difference value of the front and rear shafts of the vehicle is larger than the preset difference value, the front and rear shafts of the vehicle are controlled to conduct torque transfer within the maximum torque boundary value range, so that the rotating speeds of the front and rear shafts can be rapidly synchronized, and the vehicle can have better traction force; and the phenomenon that the vehicle slips easily if the torque exceeds the maximum torque boundary value when the vehicle transfers the torque of the front shaft and the rear shaft can be avoided, and the trafficability and the safety of the vehicle are improved.
一种车辆前后轴扭矩控制方法、装置、设备及可读存储介质,车辆前后轴扭矩控制方法包括:根据车辆每个车轮的法向受力、路面附着系数及最大滑移率,确定车辆前后轴的最大扭矩边界值;当车辆前后轴的转速差值大于预设差值时,控制车辆前后轴在最大扭矩边界值范围以内进行扭矩转移。本申请通过,当车辆前后轴的转速差值大于预设差值时,控制车辆前后轴在最大扭矩边界值范围以内进行扭矩转移,从而可以快速的同步前后轴的转速使得车辆能够拥有更好的牵引力,并且能够避免车辆在转移前后轴扭矩时若超出最大扭矩边界值容易出现车辆打滑的现象,提升了车辆的通过性和安全性。
