Patent ID: 7918194

Claim:
A cooling device for a vehicle provided at a vehicle at which engine control is carried out which stops an engine due to establishment of preset engine stoppage conditions and restarts the engine due to establishment of engine start conditions, the cooling device comprising: a heat exchanger for cooling at which heat exchange with a coolant is carried out due to cooling wind being guided; a single cooling fan which, by being rotated and driven operates and guides the cooling wind to the heat exchanger for cooling; a first driving unit able to operate the cooling fan by driving force of the engine; a second driving unit able to operate the cooling fan by driving force of an electric motor; a detecting unit detecting a cooling load on the heat exchanger for cooling; a speed detecting unit detecting a traveling speed of the vehicle; a judging unit judging a cooling capacity of the heat exchanger for cooling with respect to the cooling load on the basis of results of detection of the detecting unit; and a cooling control unit which, on the basis of results of judgment of the judging unit, selects either one of the first driving unit or the second driving unit and operates the cooling fan, and which further selects the first driving unit to operate the cooling fan if it is judged that the cooling capacity is low with respect to the cooling load, and, if the second driving unit is selected or the traveling speed detected by the speed detecting unit is greater than or equal to a predetermined speed.
