Description
次に、本発明の第2実施形態について説明する。本実施形態は、目標電力量補正処理の内容が第1実施形態と相違する。以下、その相違点を中心に説明する。
ステップS91において、電子制御ユニット200は、第2推定床温Test2が活性開始温度T1未満であるか否かを判定する。電子制御ユニット200は、第2推定床温Test2が活性開始温度T1未満であれば、ステップS92の処理に進む。一方で電子制御ユニット200は、第2推定床温Test2が活性開始温度T1以上であれば、ステップS93の処理に進む。なお本実施形態では、本ステップにおいて第2推定床温Test2が活性開始温度T1未満か否かを判定してステップS92の処理に進むか、又はステップS93の処理に進むかを決定していたが、第2推定床温Test2が活性化温度T2未満か否かを判定してステップS92の処理に進むか、又はステップS93の処理に進むかを決定するようにしてもよい。
