Abstract
In a cooling control system for controlling cooling of an engine room of an engine, a water pump and/or cooling fans are arranged within the engine room to cool same, and electric motors electrically drive the water pump and cooling fans. A control unit compares a temperature of the engine detected by a temperature sensor with a plurality of different predetermined values, and based upon results of the comparison, controls the electric motors for driving the cooling fans in such a manner that as the detected temperature is higher, the flow rate of cooling air flowing in the engine room is larger. The control unit is operable when abnormality occurs in sensors for sensing operating conditions of the engine, for operating the electric motors to drive the water pump and cooling fans. Alternatively, an analog circuit is operable when abnormality occurs in the control unit, for operating the electric motors to drive the water pump and the cooling fans.
