The invention discloses a new energy automobile hybrid power system. The new energy automobile hybrid power system comprises an electric auxiliary driving system, an engine, an electromagnetic clutch,an exhaust control system, a generator and a controller, the power output end of the electric auxiliary driving system is in transmission connection with a flywheel of the engine through the electromagnetic clutch, and the controller controls separation or connection of the electromagnetic clutch; the power input end of the generator is connected with the exhaust control system; and the controller detects the electric quantity of a battery in the electric auxiliary driving system and the fuel consumption rate of the engine in the working process through a sensor. The invention further discloses a control method. The flywheel is driven by the electric auxiliary driving system to rotate so as to assist the engine in starting, starting and running; the engine is located in the area with thelowest fuel consumption rate in the running process of the automobile, the fuel consumption of the automobile is reduced, a starting motor does not need to be independently arranged to drive the engine to be started, the structural design is ingenious, and the fuel consumption and the cost investment of the starting motor are saved.

    本发明公开了一种新能源汽车混合动力系统,包括电动辅助驱动系统、发动机、电磁离合器、排气控制系统、发电机和控制器,电动辅助驱动系统的动力输出端通过电磁离合器与发动机的飞轮传动连接,控制器控制电磁离合器的分离或接合;发电机的动力输入端与排气控制系统连接;控制器通过传感器检测电动辅助驱动系统中的电池电量和发动机工作过程中的燃油消耗率;本发明还公开了一种控制方法。本发明通过电动辅助驱动系统驱动飞轮转动而辅助发动机启动、起步和行驶,使汽车在行驶的过程中发动机处于最低燃油消耗率区域,既降低了汽车燃油的油耗,又无需再单独设置启动电机驱动发动机启动,结构设计巧妙,节省了燃油的消耗量和启动电机的成本投入。
