PROBLEM TO BE SOLVED: To reduce vibration, and improve fuel consumption in a hybrid vehicle constituted so as to output motive power of a heat engine and an electric motor via a transmission. SOLUTION: An engine 10 and a motor 20 are mounted as a motive power source so that the hybrid vehicle is constituted for transmitting motive power of these motive power sources to a driving shaft via the transmission 100. In the engine 10 and the motor 20, the motive power distribution is set according to residual fuel for a fuel cell in a range for satisfying required motive power. A control unit 70 controls the transmission ratio and lockup of the transmission 100 according to a map with output torque of the motor 20 as a parameter besides a vehicle speed and accelerator opening. As the motive power of the motor 20 becomes large, the small transmission ratio is used, and a lockup area becomes wide. Control of the transmission is switched according to the motive power of the motor 20 to reduce the vibration of the engine 10 as well as to improve the fuel consumption. |
