摘要： An apparatus for controlling an electrically operated cooling fan used for a cooling device to cool an engine block by circulating cooling water between the block and a radiator. The apparatus includes an electronic control unit (ECU), which controls the fan, and a cooling water temperature sensor, which detects the cooling water temperature. The ECU energizes a motor to rotate the fan when the detected value of the cooling water temperature becomes equal to or higher than a predetermined value. The ECU starts measuring elapsed time when the fan begins to rotate. After the measured time reaches a predetermined second reference value, the ECU computes the altering rate of the cooling water temperature. If it is determined that the altering rate is lower than a predetermined third reference value, the ECU de-energizes the fan motor. Accordingly, the rotation of the fan is stopped when the altering rate of the cooling water temperature, measured after the fan starts rotation, is rather low. Therefore, the fan is only rotated when necessary.

摘要： A malfunction detecting apparatus of a radiator fan system includes a steady-state discrimination unit which detects whether an operating condition of an internal combustion engine is in a steady state. A temperature change measuring unit measures a change in a temperature of cooling water of the engine when the operating condition of the engine is detected to be in the steady state and a control signal to start rotation of a cooling fan of the radiator fan system is output. A malfunction detecting unit detects that a malfunction in the radiator fan system has occurred when the temperature change measured by the temperature change measuring unit is smaller than a reference value.
