VEHICLE DRIVING SYSTEM

摘要

The vehicle driving system 1 includes first and second engines ENG1 and ENG2; first and second transmissions TM1 and TM2 that shift the output of the first and second engines ENG1 and ENG2; first and second one-way clutches OWC1 and OWC2 that are provided in each output portion of the first and second transmissions TM1 and TM2; a driving target member 11 that is commonly connected to the output members 121 of the first and second one-way clutches OWC1 and OWC2 via the clutch mechanisms CL1 and CL2 and transmits the rotational power transmitted to the output members of the respective one-way clutches OWC1 and OWC2 to the driving wheel 2; a main motor/generator MG1 that is connected to the driving target member 11; a sub motor/generator MG2 that is connected to the output shaft S1 of the first engine NG1; a battery 8 that sends and receives the electric power between both motor/generators; a synchronization mechanism 20 that connects and disconnects the driving target member 11 and the output shaft S2 of the second engine ENG2; and a controller 5 that controls the respective elements. As a result, a vehicle driving system is provided which can reduce fuel consumption with high efficiency.
