PROBLEM TO BE SOLVED: To eliminate a sense of incompatibility when an accelerator pedal is operated, while maintaining the remaining capacity of a battery.SOLUTION: A control device 24 determines propriety of electric power generation of an electric generator 13 according to a state of a storage battery 11; sets, when permitting the electric power generation, rotation speed of an internal combustion engine by which the electric generator 13 can perform electric power generation required for cruising; sets an additional internal combustion engine rotation speed which enables electric power generation according to a required electric power amount; and controls the internal combustion engine 12 and the electric generator 13 according to the internal combustion engine rotational speed and the additional internal combustion engine rotational speed. The electric power necessary for temporary acceleration and the EV travel of the vehicle can be covered by the electric power of battery 11 by covering the electric power that can cover the output necessary to cruise by the power generation quantity by the internal combustion engine rotating speed, while supplementing a prescribed margin with the addition internal combustion engine rotating speed. As a result, driving can be performed near the fuel consumption best point, while miniaturizing the internal combustion engine 12, and the sense of incompatibility of the driver can be eliminated when reducing fuel consumption, reducing CO2 emission, and operating an accelerator pedal. |
