PROBLEM TO BE SOLVED: To provide a target unit operation point satisfying a target traveling efficiency in a hybrid vehicle transmitting, at least, one of the powers of an internal combustion engine and a motor to an output shaft via a staged transmission. SOLUTION: Storage state detecting means 13 detects the storage state SOC of a capacitor device 10. Target traveling efficiency calculation means 14 calculates a target value of the traveling efficiency, or a ratio of a prescribed physical quantity to the driving power required for the driving of a vehicle and calculates the target value smaller, as an SOC detection value is higher. Target unit operation point calculation means 15 calculates a target value of the unit operation point to be a target traveling efficiency among operation points of a unit 11 (internal combustion engine 1, clutch 2, motor 3, and staged transmission 4) covering the power generated by the internal combustion engine 1 at the highest traveling efficiency. Target unit operation point providing means 16 drives the unit 11 at the target unit operation point. |
