Summary:To accurately estimate an amount of condensate water generated in an exhaust passage in an internal combustion engine.SOLUTION: In step S14, a CPU executes estimation processing for estimating a generation amount AC per unit time of condensate water generated in an exhaust passage. In the processing of step S14, the CPU estimates the generation amount AC to be smaller as an exhaust temperature TE is higher.SELECTED DRAWING: Figure 2 【課題】内燃機関で排気通路に発生する凝縮水の量を正確に推定する。【解決手段】ステップＳ１４では、ＣＰＵは、排気通路に発生する凝縮水の単位時間当たりの発生量ＡＣを推定する推定処理を行う。ステップＳ１４の処理では、ＣＰＵは、排気温ＴＥが大きいほど、発生量ＡＣを少なく推定する。【選択図】図２
