To suppress an increase in a difference between intake air amounts to be introduced to two cylinder groups.SOLUTION: A control device for an internal combustion engine executes: processing for calculating a first provisional value XR1 as a provisional value of a first upper limit value X1 on the basis of a temperature detected by a first temperature sensor (Step S110); processing for calculating a second provisional value XR2 as a provisional value of a second upper limit value X2 on the basis of a temperature detected by a second temperature sensor (Step S210); and processing for calculating the first provisional value XR1 as the first upper limit value X1 when the first provisional value XR1 is equal to or smaller than a second correction value XH2 obtained by multiplying the second provisional value XR2 by a correction coefficient VU, and calculating a value that is the second provisional value XR2 or larger and is smaller than the first provisional value XR1 as the first upper limit value X1 when the first provisional value XR1 is larger than the second correction value XH2 (Step S130).SELECTED DRAWING: Figure 2 【課題】２つの気筒群に導入する吸気の量の差が大きくなることを抑制する。【解決手段】第１温度センサが検出した温度に基づいて第１上限値Ｘ１の暫定値として第１暫定値ＸＲ１を算出する処理（ステップＳ１１０）と、第２温度センサが検出した温度に基づいて第２上限値Ｘ２の暫定値として第２暫定値ＸＲ２を算出する処理（ステップＳ２１０）と、第１暫定値ＸＲ１が第２暫定値ＸＲ２に補正係数ＶＵを乗じた第２補正値ＸＨ２以下である場合に、第１暫定値ＸＲ１を第１上限値Ｘ１として算出し、第１暫定値ＸＲ１が第２補正値ＸＨ２より大きい場合に、第２暫定値ＸＲ２以上で第１暫定値ＸＲ１未満の値を第１上限値Ｘ１として算出する処理（ステップＳ１３０）と、を実行する。【選択図】図２
