PROBLEM TO BE SOLVED: To solve a problem in which a fan drive noise is tend to be noticed by a passenger if the frequency of the fan drive noise is different from that of an engine drive noise.SOLUTION: A vehicle includes: an engine (15) and a battery (11) as power sources for driving the vehicle; a sensor (31) for detecting a revolution speed of the engine; a sensor (32) for detecting an engine knocking; a fan (43) for supplying the battery with air of a passenger compartment; and a controller (21) for controlling driving of the fan. When an engine knocking is occurring, the controller calculates a frequency of a drive noise of an engine on the basis of the engine revolution speed. Further, when driving the fan, the controller sets a rotation speed of the fan so that the frequency of the fan drive noise matches that of the engine driving noise. |
