The invention discloses a double-motor electric vehicle driving system, and the system comprises a main controller, a first motor, a second motor, a first brake, a second brake, a third brake, a Simpson planetary gear row and a power output unit. The first motor, the second motor, the first brake, the second brake and the third brake are all connected with the main controller; output shafts of the first motor and the second motor are connected with the Simpson planetary gear row, and the first brake is arranged on the output shaft of the first motor; and the second brake and the third brake are arranged on the Simpson planetary gear row. According to the invention, a dual-motor mode of multiple single-motor modes is provided, so that the electric vehicle can adapt to more working conditions. In addition, the main controller selects one driving mode from the six driving modes to drive the electric vehicle according to the optimal efficiency principle, and the power performance and the economic performance of the electric vehicle can be greatly improved.

    本发明公开了一种双电机电动汽车驱动系统,包括:主控制器、第一电机、第二电机、第一制动器、第二制动器、第三制动器、辛普森行星齿轮排以及动力输出单元;第一电机、第二电机、第一制动器、第二制动器、第三制动器均与主控制器连接;第一电机以及第二电机的输出轴均与辛普森行星齿轮排连接,第一制动器设于第一电机的输出轴上;第二制动器以及第三制动器设于辛普森行星齿轮排上;本发明具有多种单电机模式的双电机模式,能使电动汽车适应更多工况。另外本发明主控制器根据效率最优原则从6种驱动模式中选择一种驱动模式驱动电动汽车,能使电动汽车的动力性能和经济性能都得到很大的提升。
