Abstract:
A hybrid vehicle control device comprising: an engine that is capable of temporary stoppage control in a prescribed operating condition, an infinitely variable gear-change mechanism connected to the output shaft of said engine and whereby the output rotation thereof is subjected to infinitely variable change of gear ratio, a driving force transmission system that transmits the output of said infinitely variable gear-change mechanism to the drive wheels, and an electrically driven motor capable of driving said vehicle wheels and arranged parallel with said engine, further comprising:a first hydraulic pump that is driven by said engine; and a second hydraulic pump that is driven by an electric motor for pump drive, wherein during running with said engine stopped in said prescribed operating condition, gear-change control is performed by driving said second hydraulic pump by said electric motor for pump drive such that the gear ratio of said infinitely variable gear-change mechanism is made to have a value matching the current operating condition, by using hydraulic pressure obtained from said second hydraulic pump.
