<P>PROBLEM TO BE SOLVED: To prevent shock when the start of an engine is overlapped with the release of a parking lock. <P>SOLUTION: A shift control device is provided for a hybrid vehicle having an output member for outputting torque output from the engine to driving wheels, a parking mechanism for suspending the rotation of the output member when a parking position is selected, and a motor for supplying torque to a transmission mechanism relative to the driving wheels. The shift control device includes: a torque correction means for increasing and correcting the motor output torque to reduce the torque functioning to the parking mechanism by means of twist torque stored in the transmission mechanism, prior to the release of locking the output member (step S3); a lock release means for releasing the lock stopping the rotation of the output member while the motor output torque is being increased and corrected (step S4); and a torque correction restoration means for restoring the torque to the state prior to the increase and the correction, by gradually decreasing the increase correction amount of the motor output torque after the lock of the output member is released (step S5). <P>COPYRIGHT: (C)2011,JPO&INPIT |
