The embodiment of the invention provides a torque distribution method, device and equipment and a vehicle. The method comprises the following steps: determining a front and rear axle demand torque distribution ratio of a vehicle according to a driving parameter group of the vehicle; under the condition that the front and rear axle demand torque distribution ratio is larger than or equal to the preset front and rear axle demand torque distribution ratio, the front axle demand torque and the rear axle demand torque of the vehicle are determined according to the total demand torque of the vehicle and the front and rear axle demand torque distribution ratio; under the condition that the front and rear axle demand torque distribution ratio is smaller than a preset front and rear axle demand torque distribution ratio and the vehicle has the first steering intention, a first steering promotion control slope is determined based on the vehicle speed of the vehicle; the larger one of the front axle demand torque and the rear axle demand torque is increased according to the first steering promotion control slope, and the smaller one of the front axle demand torque and the rear axle demand torque is reduced according to the first steering promotion control slope, so that the driving controllability of the vehicle during steering can be improved.
本说明书实施方式提供了一种扭矩分配方法、装置、设备和车辆。所述方法包括:根据车辆的行驶参数组,确定车辆的前后轴需求扭矩分配比值;在前后轴需求扭矩分配比值大于或等于预设前后轴需求扭矩分配比值的情况下,根据车辆的总需求扭矩和前后轴需求扭矩分配比值,确定车辆的前轴需求扭矩和后轴需求扭矩;在前后轴需求扭矩分配比值小于预设前后轴需求扭矩分配比值,且车辆具有第一转向意图的情况下,基于车辆的车辆速度确定第一转向促进控制斜率;根据第一转向促进控制斜率增大前轴需求扭矩和后轴需求扭矩中的较大者,以及根据第一转向促进控制斜率减小前轴需求扭矩和后轴需求扭矩中的较小者,如此,可以提高车辆在转向时的行驶操控性。
