A knock determination unit is configured to determine whether the internal combustion engine causes knocking. A knock control unit is configured to perform a knock control to correct an ignition timing on the basis of the determination. A water pump is configured to circulate cooling fluid of the internal combustion engine. A pump control unit is configured to perform a cooling control to control the water pump so as to further cool the internal combustion engine in a detection state, where the knock determination unit detects knocking, than in a non-detection state where the knock determination unit does not detect knocking.
