<P>PROBLEM TO BE SOLVED: To suppress shock from occurring along with release of torsion torque when a parking gear is unlocked in restart of the operation by accumulating the torsion torque in a drive system due to power transmission at a reverse gear stage by making an automatic shift in a blocked state through the reverse gear stage when shift operation to a parking position "P" is performed. <P>SOLUTION: The torsion torque tnejire is calculated (step S2) based on engine rotation speed NE<SB>R</SB>on formation of the reverse gear stage when the shift operation to the parking position "P" is performed. A second motor generator MG2 is actuated so that torque opposite to the torsion torque tnejire may be applied (step S3). Accordingly, the torsion torque tnejire is prevented from being suddenly released when the parking gear is unlocked, and the torsion torque tnejire is gently released (step S5) by torque reduction control of the second motor generator MG2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
