The invention relates to a dual-motor hybrid power system for a commercial vehicle and a control method. The system comprises an engine, a power generation motor, a first clutch, a power distribution mechanism, an automatic gearbox, a driving motor, a second clutch, a motor controller and a storage battery. The engine is connected with the power generation motor for power generation; the power generation motor is connected with the power distribution mechanism through a first clutch; the driving motor is connected with the power distribution mechanism through a second clutch; the power generation motor, the storage battery and the driving motor are all connected with the motor controller; the power distribution mechanism is connected with the transmission mechanism through the automatic gearbox; the motor controller controls the power generation motor and the driving motor by controlling positive and negative torque instructions, under the condition of the negative torque instruction, the automatic gearbox provides torque for the driving motor and the power generation motor through the power distribution mechanism, inertia braking energy generated by braking of a brake and the like is recycled, and the energy is stored in the storage battery. And recycling of the battery is ensured.

    本发明涉及一种商用车用双电机混合动力系统及控制方法,该系统包括发动机、发电电机、第一离合器、动力分配机构、自动变速箱、驱动电机、第二离合器、电机控制器、蓄电池;发动机和发电电机连接用于发电;发电电机通过第一离合器与动力分配机构连接;驱动电机通过第二离合器与动力分配机构连接;发电电机、蓄电池、驱动电机均与电机控制器连接;动力分配机构通过自动变速箱与传动机构连接;电机控制器通过控制正负转矩指令来控制发电电机、驱动电机,在负转矩指令的情况下,自动变速箱通过动力分配机构将转矩提供给驱动电机和发电电机,回收因为刹车等制动产生的惯性制动能量,并且将该能量存储到蓄电池中,保证电池循环利用。
