<P>PROBLEM TO BE SOLVED: To reasonably and suitably preheat an engine and its related parts. <P>SOLUTION: A hybrid ECU determines that a driver has an intention of starting traveling when a starter switch is changed over from the off-state to the on-state (S110), the temperature of each item (cooling water in the engine, injector and lubricating oil) is input (S120), the necessity of preheat is determined depending on whether or not each item reaches a suitable temperature range (S130), when preheat is necessary, an engine start permitting flag is set to "0" to inhibit starting of the engine (S140), and subsequently, an instruction for preheating of the item required to be preheated is given to the engine ECU (S150) to end the program. On the other hand S130, when all items reach suitable temperature range, preheating is determined to be unnecessary, and the engine starting permitting flag F is set to "1" to permit starting of the engine (S160) to end the program. <P>COPYRIGHT: (C)2004,JPO |
