<p>PROBLEM TO BE SOLVED: To suppress thermal strain of an intercooler core of a water-cooling type intercooler which accompanies deceleration and acceleration of a vehicle.SOLUTION: A throttle sensor 53 monitors the closing speed of a throttle valve 20 which meters the flow rate of suction air supercharged by a supercharger and sucked into an internal combustion engine. When the monitored closing speed of the throttle valve 20 is equal to or larger than a predetermined speed, an electric water pump 20, the electric water pump 40 which circulates cooling water of the intercooler 10 is temporarily stopped from being driven for a predetermined time.</p> |
