ABSTRACT:
When a starter switch is switched from OFF to ON, a hybrid ECU determines that a driver intends to start driving a vehicle, reads a temperature of each of items (engine coolant, injectors, lubricating oil, and the like), and makes a determination on the necessity of preheating depending on whether each of the items has reached a corresponding one of suitable temperatures. If preheating is required, the hybrid ECU sets an engine start permission flag so as to prohibit the engine from being started, and instructs an engine ECU to preheat the item requiring preheating. On the other hand, if every one of the items has reached the suitable temperature range of its own, the hybrid ECU determines that preheating is not required, and sets the engine start permission flag so as to permit the starting of the engine.
