The invention provides a torque distribution method, electronic equipment, a vehicle power system and a vehicle, and the torque distribution method comprises the steps: determining the target torque of the vehicle and the torque distribution proportion of a front axle motor and a rear axle motor of the vehicle according to the parameter information of the vehicle, the parameter information of the vehicle comprises a road adhesion coefficient and air pressure borne by the vehicle at the current vehicle speed; according to the target torque and the torque distribution proportion, the first torque of the front axle motor and the second torque of the rear axle motor are determined; and distributing the first torque and the second torque to a front axle motor and a rear axle motor respectively. According to the torque distribution method, the torque of the front axle motor and the torque of the rear axle motor can be adjusted in real time according to the change of the vehicle speed and the change of the vehicle driving road surface, the adaptability to different working conditions and different driving road surfaces is better, the power performance of the front axle motor and the power performance of the rear axle motor are brought into full play, and the user experience is effectively improved.

    本申请提出一种转矩分配方法、电子设备、车辆动力系统和车辆,其中,转矩分配方法包括:根据车辆的参数信息,确定车辆的目标转矩以及车辆的前轴电机和后轴电机的转矩分配比例,其中,车辆的参数信息包括路面附着系数和车辆在当前车速下受到的空气下压力;根据目标转矩和转矩分配比例,确定前轴电机的第一转矩和后轴电机的第二转矩;将第一转矩和第二转矩分别分配至前轴电机和后轴电机。根据本申请实施例的转矩分配方法,能够根据车辆的车速变化以及车辆行驶路面的变化实时调整前轴电机和后轴电机的转矩,对不同工况以及不同行驶路面的适应性更好,最大化发挥前轴电机和后轴电机的动力性能,有效提升用户体验。
