The invention provides a pure electric four-wheel-drive torque distribution method and system and a vehicle, and the method comprises the steps: calculating a four-wheel-drive torque distribution coefficient based on the efficiency of a front electric drive system, the efficiency of a rear electric drive system, zero torque power loss, the torque control precision of the electric drive systems and the change of electric drive terminal voltage; the influence of the continuous voltage change on the four-wheel-drive torque distribution coefficient in the vehicle driving process is simulated, and the influence of the continuous voltage change of the electric drive end on the four-wheel-drive torque distribution coefficient in the actual vehicle driving process can be simulated.

    本发明提供了一种纯电动四驱扭矩分配方法、系统及车辆,本发明基于前、后电驱系统效率,零扭矩功率损失、电驱系统扭矩控制精度及电驱端电压的变化计算四驱扭矩分配系数,且通过查找四驱扭矩分配系数的方法,模拟车辆行驶中电压的连续变化对四驱扭矩分配系数的影响,可以模拟车辆在实际行驶过程中电驱端电压连续变化对四驱扭矩分配系数的影响。
