The multi-gear power split hybrid transmission gear shifting control system comprises an engine, a multi-gear power split hybrid transmission, an EM1 motor, an EM2 motor and a gear shifting execution mechanism, the engine is controlled by an EMS engine controller, the EM1 motor and the EM2 motor are controlled by a PEU motor controller, and the EMS engine controller is connected with the PEU motor controller. The gear shifting executing mechanism is controlled by an SAU gear shifting actuator controller, all systems are controlled by a vehicle control unit in the gear shifting process, and the SAU gear shifting actuator controller responds to gear taking-off and gear engaging instructions sent by the vehicle control unit and controls the gear shifting executing mechanism to act. The vehicle control unit carries out control instruction interaction with the engine controller, the PEU controller and the SAU gear shifting actuator controller through CAN communication, and has the advantages that automatic control over gear shifting of an engine and an EM2 (TM) motor is carried out; meanwhile, a control method for gear shifting of the engine is creatively provided, and the application problem of clutch-free gear shifting control of the engine is solved.

    本发明公开了一种多挡位功率分流混动变速器换挡控制系统及控制方法,包括发动机、多挡位功率分流混动变速箱、EM1电机、EM2电机以及换挡执行机构,发动机由EMS发动机控制器进行控制,EM1电机及EM2电机由PEU电机控制器进行控制,换挡执行机构由SAU换挡执行器控制器进行控制,在换挡过程中各系统由整车控制器进行控制,其中SAU换挡执行器控制器响应整车控制器发送的摘挡及挂挡指令,控制换挡执行机构动作,整车控制器通过CAN通信与发动机控制器、PEU控制器和SAU换挡执行器控制器进行控制指令交互,其优点在于,进行发动机和EM2(TM)电机换挡的自动化控制;同时,创造性地提出了发动机换挡的控制方法,解决了发动机无离合器换挡控制的应用难题。
