The embodiment of the invention provides a torque distribution method and system and a vehicle, and relates to the technical field of automobiles, and the method comprises the steps that vehicle state information of the current vehicle and rated output torque of a front axle motor and rated output torque of a rear axle motor are obtained; according to the vehicle state information, determining the road surface condition of the road section where the current vehicle is located and the demand torque of the current vehicle; under the condition that the road surface of the road section where the current vehicle is located is a non-flat road surface, torque distribution is conducted on a front axle motor and a rear axle motor according to the required torque according to a preset torque distribution proportion; and redistributing the torque of the front axle motor and the torque of the rear axle motor according to the magnitude relationship between the torque distributed to the front axle motor and the rated output torque of the front axle motor and the magnitude relationship between the torque distributed to the rear axle motor and the rated output torque of the rear axle motor. According to the embodiment of the invention, the torque of the front axle motor and the rear axle motor is reasonably distributed, so that good economical efficiency of the vehicle can be ensured on the premise of meeting the dynamic property of the vehicle.

    本申请实施例提供了一种扭矩分配方法、系统以及车辆,涉及汽车技术领域,所述方法包括:获取当前车辆的车辆状态信息以及前桥电机和后桥电机各自的额定输出扭矩;根据车辆状态信息,确定当前车辆所处路段的路面情况以及当前车辆的需求扭矩;在当前车辆所处路段的路面为非平坦路面的情况下,将需求扭矩按照预设扭矩分配比例对前桥电机和后桥电机进行扭矩分配;根据分配给前桥电机的扭矩与前桥电机的额定输出扭矩的大小关系和分配给后桥电机的扭矩与后桥电机的额定输出扭矩之间的大小关系,对前桥电机和后桥电机的扭矩进行再分配。本申请实施例通过对前后桥电机扭矩的合理分配,在满足车辆的动力性的前提下,能够确保车辆有较好的经济性。
