Abstract
In a hybrid vehicle having a locking mechanism in which a play elimination process is required in the locking, a torque shock in the play elimination is reduced. In a hybrid vehiclehaving a locking mechanismwhich is a cam-lock type engaging apparatus, an ECUperforms MGlocking control. In the control, play is formed between a camand a clutch plateof the locking mechanism. The formed play is gradually reduced such that the torque shock in the play elimination does not occur due to the phase control of the cam, on the basis of an initial value of the amount of the play when the clutch plateis bought into contact with a friction partand a play elimination amount G.
