Hybrid vehicle including a control device

摘要

A hybrid vehicle includes: a metal V-belt type infinitely variable gear-change mechanism 20 whereby the rotation of an engine E is subjected to change in gear ratio, a forwards clutch 14 and a reverse brake 15 that perform engagement/disengagement control of the engine and the infinitely variable gear-change mechanism, and a second motor generator 50 capable of driving the drive wheels arranged parallel with the engine. The control device is provided with a first hydraulic pump 3 for engine drive, a second hydraulic pump 56 that is driven by an electric motor 55 for pump drive, and a forwards/reverse clutch control valve 73 that performs changeover control of supply of working hydraulic pressure to the forwards clutch 14 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.
