The invention relates to a dual-motor pure electric power system. Comprising a first motor, a second motor, a first transmission mechanism connected with the first motor, a second transmission mechanism connected with the second motor, an intermediate shaft connected with the first transmission mechanism and the second transmission mechanism, and a first one-way clutch located between the intermediate shaft and the first transmission mechanism. The first one-way clutch is located between the middle shaft and the first transmission mechanism, the second one-way clutch is located between the middle shaft and the second transmission mechanism, the third transmission mechanism is connected with the middle shaft, and the wheels are connected with the third transmission mechanism. Correspondingly, the invention further provides an automobile based on the power system and a control method. The dual-motor pure electric power system provided by the invention can meet the power performance requirements of the whole vehicle under the working conditions of starting, rapid acceleration and the like; and the power consumption is effectively reduced, and the system can be used as an independent front-drive or rear-drive power system for the four-wheel-drive new energy vehicle.

    本发明涉及一种双电机纯电动的动力系统,包括第一电机、第二电机、与所述第一电机相连接的第一传动机构、与所述第二电机相连接的第二传动机构、与所述第一传动机构与第二传动机构相连接的中间轴、位于所述中间轴与所述第一传动机构之间的第一单向离合器、位于所述中间轴与所述第二传动机构之间的第二单向离合器、与所述中间轴相连接的第三传动机构以及与所述第三传动机构相连接的车轮。相应的,本发明还提供基于动力系统的汽车及控制方法。本发明提供的双电机纯电动的动力系统,可以满足整车在起步、急加速等工况下的动力性能需求;有效降低了电耗,可以用于四驱新能源车作为单独的前驱或者后驱动力系统。
