Abstract
When neutral control is started by placing a CVT drive clutch in a semi-engaged state while a vehicle is decelerating in a state where a second power transmission path is established, a clutch mechanism that is semi-engaged in neutral control while the vehicle is decelerating is changed from the CVT drive clutch to a forward clutch before a stop of the vehicle, so it is possible to continue the neutral control until a stop of the vehicle. At a stop of the vehicle, a power transmission path is already changed to a first power transmission path that establishes a gear ratio (EL) higher than a highest gear ratio (γmax) that can be established by the second power transmission path. Thus, right after a stop of the vehicle, it is possible to execute idle stop control.
