Patent ID: 7725222

Claim:
A control device of a hybrid vehicle including a motive power distribution mechanism that distributes an output of an engine to a first motor-generator and to an output shaft at a driving wheel side, a second motor-generator that outputs a power to the output shaft via a stepped type transmission, and an electricity storage device, comprising: a startup-time control device that, in response to an activating operation of the hybrid vehicle, engages a hydraulic type friction engagement device provided in the stepped type transmission and sets a ready-to-run state based on a predetermined pressure of the hydraulic type friction engagement device; a hydraulic pump that is rotationally driven by the engine to feed a working oil; and a run region determination device that determines whether the hybrid vehicle is in a motor run region or a non-motor run region, wherein if the run region determination device determines that the hybrid vehicle is in the non-motor run region, the startup-time control device sets an original pressure of the hydraulic type friction engagement device at a first predetermined pressure as the engine is started up, and sets the original pressure at a second predetermined pressure after the engine undergoes a complete explosion.
