PROBLEM TO BE SOLVED: To prevent a driving device from exceeding a high temperature even when a vehicle is temporarily stopped during a travel of the vehicle, to prevent the driving device from being overcooled, and also, to prevent a wasteful power consumption from occurring. SOLUTION: This air cooling device for vehicle is equipped with the driving device 15 for traveling which is supported by a car body 2, a cooling fan 30 which can cool the driving device 15, and a temperature sensor 31 which detects the temperature of the driving device 15. The cooling fan 30 is driven based on the detection value of the temperature sensor 31. When the variation ratio of the detection value when the temperature rises exceeds a set value B, the cooling fan 30 is driven. COPYRIGHT: (C)2006,JPO&NCIPI |
