A control device and control method for a hybrid vehicle is disclosed having an electric storage detecting section 13 which detects a state of charge (SOC) of an electric storage device 10. A target running efficiency calculating section 14 serves as a unit to calculate a target value of a running efficiency, indicative of a proportion of a given physical quantity, in terms of a drive power rate required for driving the vehicle such that the higher the SOC detected value, the smaller will be the target value. A target unit operating point calculating section 15 calculates a target value of a unit operating point, providing the target running efficiency, from among operating points, that cause a power rate of an internal combustion engine 1 to be utilized at the running efficiency with the maximum efficiency, of a unit 11 (the internal combustion engine 1, a clutch 2, a motor 3 and a stepped power transmission 4), and a target unit operating point actualizing section 16 operates the unit 11 at the target unit operating point.
