<P>PROBLEM TO BE SOLVED: To prevent generation of rattling noise when an operation state of an internal combustion engine is switched, in a hybrid vehicle preventing the generation of rattling noise in a power transmission system by pressing torque of an electric motor. <P>SOLUTION: In a hybrid vehicle, when an engine is in a cold state, an action direction of pressing torque is fixed in one direction even when an operation state of the engine is switched between a load operation and a self-sustained operation. Further, the magnitude of the pressing torque in this case is set larger than that of the pressing torque when the engine is in a hot state. When a shift operation device is operated from a P position to a non-P position, a reduction amount per unit time of the pressing torque is set large until the pressing torque decreases to a predetermined value, and the state in which a side surface of a tooth of a parking gear is strongly pressed to a parking lock pole is eliminated early. <P>COPYRIGHT: (C)2013,JPO&INPIT |
