The invention provides a torque distribution method and device of a vehicle and the vehicle. The torque distribution method comprises the steps that the actual opening degree of an accelerator pedal is obtained, and the current total torque requirement of a driver is determined according to the actual opening degree; calculating a front axle target distribution torque and a rear axle target distribution torque according to the current front axle torque distribution coefficient and the current total torque demand of the vehicle; a left front wheel target distribution torque and a right front wheel target distribution torque are obtained according to the current left front wheel torque distribution coefficient and the front axle target distribution torque of the vehicle, and a left rear wheel target distribution torque and a right rear wheel target distribution torque are obtained according to the current left rear wheel torque distribution coefficient and the rear axle target distribution torque of the vehicle. According to the method, the target distribution torque of each wheel can be determined through the torque distribution coefficients of the front and rear axles and the torque distribution coefficient of each wheel, the problems of acceleration slip, bend head pushing or drifting and the like caused by improper torque distribution of the front and rear wheels are solved, and the acceleration performance, sensitivity, passing ability and stability of vehicle response are improved.

    本申请提供了车辆的扭矩分配方法、装置及车辆,包括:获取加速踏板的实际开度,并根据实际开度确定驾驶员的当前总扭矩需求;根据车辆的当前前轴扭矩分配系数和当前总扭矩需求计算前轴目标分配扭矩和后轴目标分配扭矩;根据车辆的当前左前轮扭矩分配系数和前轴目标分配扭矩得到左前轮目标分配扭矩和右前轮目标分配扭矩,并根据车辆的当前左后轮扭矩分配系数和后轴目标分配扭矩得到左后轮目标分配扭矩和右后轮目标分配扭矩。该方法能够通过前、后轴的扭矩分配系数以及每个车轮的扭矩分配系数确定每个车轮的目标分配扭矩,解决前、后轮扭矩分配不当引起的加速打滑、弯道推头或甩尾等问题,提升车辆响应的加速性能、灵敏性、通过性和稳定性。
