PROBLEM TO BE SOLVED: To provide a cooling system for an electronic control device capable of more suitably controlling the revolution of a cooling fan. SOLUTION: Occupants getting on in a cabin are detected using an in-vehicle camera 19, and the number of drive revolution of the cooling fan 21 is controlled according to the detection result. Accordingly, when it is detected that the passenger is not remained in the cabin, the number of drive revolution of the cooling fan 22 can be enhanced and control of the revolution of the cooling fan 22 can be more suitably performed.
