Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress the knocking of a vehicle.SOLUTION: A vehicle control device is formed, as a cooling water passage, with a first water jacket at a position relatively close to a combustion chamber, and comprises: a cylinder head formed with a second water jacket at a position relatively closer to an exhaust port, a valve for switching the communication and blockage of cooling water to the second water jacket; a temperature sensor for measuring the temperature of the cooling water; and a control part for switching the ON/OFF state of the valve. The control part sets the valve in the closed state to block the cooling water to the second water jacket, in the case the temperature measured by the temperature sensor is at or higher than a predetermined hot temperature threshold value, thereby to cause the cooling water to communicate with the first water jacket in the cylinder head.SELECTED DRAWING: Figure 4 【課題】ノッキングを抑制する。【解決手段】車両制御装置は、冷却水の流路として、相対的に燃焼室に近接する位置に第１ウォータージャケットが形成されるとともに、相対的に排気ポートに近接する位置に第２ウォータージャケットが形成されたシリンダヘッドと、第２ウォータージャケットへの冷却水の流通および遮断を切り替えるバルブと、冷却水の温度を計測する温度センサと、バルブの開閉状態を切り替える制御部と、を備え、制御部は、温度センサにより計測された温度が所定の高温閾値以上の場合に、バルブを閉状態にして第２ウォータージャケットへの冷却水を遮断し、シリンダヘッド内において第１ウォータージャケットに冷却水を流通させる。【選択図】図４
