PROBLEM TO BE SOLVED: To provide a cooling water temperature compensation device preventing erroneous determination of control using cooling water temperature by appropriately compensating cooling water temperature. SOLUTION: The cooling water temperature compensation device acquires cooling water temperature of an internal combustion engine and compensate cooling water temperature. In an embodiment, the cooling water temperature compensation device compensates cooling water temperature acquired during execution of control driving an electric water pump for a predetermined period of time when control stopping the electric water pump (stop control) is being executed. In detail, compensation is executed based on inclination of temperature change during stop control. Erroneous determination of completion of warming up is prevented during control driving the electric water pump for a predetermined period of time by determining completion of warming up of the internal combustion engine, based on cooling water temperature compensated in such a manner. Hunting of control by executing control, based on compensated cooling water temperature. COPYRIGHT: (C)2008,JPO&INPIT
