The invention relates to a multi-mode coupling driving system of a dual-motor electric vehicle, which belongs to the technical field of new energy vehicles. The system comprises a first motor, a second motor, a planetary gear mechanism, a brake, a clutch, a synchronizer, an inverter, a power battery, a first gear shaft, a second gear, a main speed reducer and a differential assembly. The clutch, the brake and the synchronizer are controlled to be engaged and disengaged, therefore, the coupling mode of the first motor and the second motor is changed, rotating speed coupling driving of the firstmotor and the second motor, torque coupling driving of the first motor and the second motor, independent driving of the first motor and independent driving of the second motor are achieved, optimal distribution of torque and rotating speed of the two motors is achieved, and economical efficiency and acceleration performance are improved.

    本发明涉及一种双电机电动汽车的多模式耦合驱动系统,属于新能源汽车技术领域。该系统包括第一电机、第二电机、行星齿轮机构,制动器,离合器,同步器,逆变器,动力电池,第一齿轮轴,第二齿轮,主减速器及差速器总成。本发明通过控制离合器、制动器与同步器的接合与分离,从而改变第一电机与第二电机的耦合方式,实现第一电机与第二电机转速耦合驱动、第一电机与第二电机转矩耦合驱动、第一电机单独驱动和第二电机单独驱动,实现了两个电机扭矩和转速的最优分配,提高了经济性和加速性能。
