Abstract
A hybrid vehicle includes: a metal V-belt type infinitely variable gear-change mechanism whereby the rotation of an engine E is subjected to change in gear ratio, a forwards clutch and a reverse brake that perform engagement/disengagement control of the engine and the infinitely variable gear-change mechanism, and a second motor generator capable of driving the drive wheels arranged parallel with the engine. The control device is provided with a first hydraulic pump for engine drive, a second hydraulic pump that is driven by an electric motor for pump drive, and a forwards/reverse clutch control valve that performs changeover control of supply of working hydraulic pressure to the forwards clutch etc. When vehicle running is performed with the engine stopped, the forwards clutch etc is disengaged by the forwards/reverse clutch control valve, and the second hydraulic pump is driven by the electric motor for pump drive, gear-change control of the infinitely variable gear-change mechanism being performed in accordance with the current driving conditions by using this hydraulic pressure.
