PROBLEM TO BE SOLVED: To provide a control device for a vehicular cooling device capable of improving engine efficiency while maintaining cooling performance of an engine at a time of hill drive of a vehicle in vehicular cooling devices using an engine drive type fan including a viscous fluid coupling structure. SOLUTION: Drive force of a crankshaft 4 which is an output shaft of the engine 2 is given to the engine drive type fan 22 via a crank pulley 6, a belt 20. The engine driven type fan 22 is provided for cooling engine cooling water in an radiator 30 and comprises a drive part 23 and a blade part 24. Rotation speed of the blade part 24 is determined by duty command value output to the drive part 23. ECU 50 control rotation speed by correcting the duty command value according to road surface inclination angles. Correction of rotation speed is done to reduction side at a time of up-grade and to increase side at a time of down-grade. COPYRIGHT: (C)2008,JPO&INPIT
