PROBLEM TO BE SOLVED: To make it possible to effectively conduct a vehicle propulsion responsive to the charging state of a battery in a driver for a vehicle having an engine and a motor generator. SOLUTION: When a battery is a normal or low charged state, a power split mode that the ring gear 21, a sun gear 22 and a carrier 23 of a planetary gear are rotated is set, the reaction torque of the output torque of the engine 1 is output by the generator 5, and a vehicle propulsion is conducted by the synthetic torque of the engine 1 and the generator 5. In this case, the energy of the gear 22 can be stored in the battery as power by generating the generator 5. When the battery is fully charged, the gear 21 is coupled to the gear 22, a direct coupling clutch Cd 25 is engaged, to an integrally rotating parallel hybrid mode, and the vehicle propulsion is conducted by the output torques of the engine 1 and the generator 5. |
