摘要：
In a hybrid vehicle 20, on a start of an engine 22, when an engine water temperature Tw is low and there is a need of advancing open and close timings of an intake valve 128 from their most delayed positions, electric power is supplied to a VVT motor 133 either via a first route R1 or via a second route R2. Even when the state of charge of a low voltage battery 53 is very low and insufficient, the required electric power is supplied from a DC-DC converter 55 to the VVT motor 133 without passing through the low voltage battery 53. On the start of the engine 22, such start control ensures an adequate change of the open and close timings of the intake valve 128 set in the stop state of the engine 22.
