The invention provides a power domain control system of a power split type hybrid vehicle. The system comprises an engine control module, a first motor control module, a second motor control module, a battery management module, a mechanical automatic transmission control module, an energy management module and a mode switching coordination control module. By integrating a hybrid controller and a transmission controller of the power split type hybrid vehicle, the number of vehicle controllers and the number of wire harnesses between the controllers can be reduced, and then the real-time performance and robustness of a vehicle power control system are improved; and meanwhile, an energy management control strategy in the hybrid controller and an economical gear shifting strategy in the transmission controller are combined in real time, so that the fuel economy of the power split type hybrid vehicle can be further improved.

    本发明提出一种功率分流式混合动力汽车动力域控制系统,包括发动机控制模块、一号电机控制模块、二号电机控制模块、电池管理模块、机械式自动变速器控制模块、能量管理模块、模式切换协调控制模块。通过将功率分流式混合动力汽车的混动控制器与变速器控制器进行集成,可减少车辆控制器的数量与控制器间的线束数量,进而提升了车辆动力控制系统的实时性与鲁棒性,同时将混动控制器中的能量管理控制策略与变速器控制器中的经济性换挡策略进行实时结合,可进一步提高功率分流式混合动力汽车的燃油经济性。
