PURPOSE: To smooth the starting of an engine when the engine is restarted after a short stopping time by continuing the control of an engine-room fan after a key switch is turned off. CONSTITUTION: An engine-room cooling fan 21 is provided in an engine room 20. The ON-OFF control of the engine-room cooling fan 21 is performed by a control unit 23 based on the output of an engine-room temperature sensor 22. After a key switch 26 is turned off, the control unit 23 continues the control of the engine-room fan 21 by the power supply of a battery 27 through a bypass line 27B for a specified time. After the elapse of the specified time, the control unit 23 turns off the power supply through the bypass line 27B itself and stops the function. The power consumption after the stop of the function disappears, and the useless consumption of the power in the battery 27 is avoided. |
