Description
続いて、上記ハイブリッド車両100を用いた触媒暖機処理について説明する。図3は、ハイブリッド車両100による触媒暖機処理の流れを説明するフローチャートである。当該触媒暖機処理は、所定時間間隔の割込処理として実行される。
HEVCU210は、ハイブリッド車両100が減速状態であるか否かを判定する。具体的に説明すると、HEVCU210は、アクセルペダルの踏み込み量が0であり、ブレーキペダルの踏み込み量が正である場合に、ハイブリッド車両100が減速状態であると判定する。その結果、減速状態であると判定した場合には、車速判定処理S120に処理を移し、減速状態ではないと判定した場合には、当該触媒暖機処理を終了する。
HEVCU210は、車速センサ180から入力された車速VSが、所定の車速下限値Vminを上回るか否かを判定する。その結果、車速VSが車速下限値Vminを上回ると判定した場合には、触媒温度判定処理S130に処理を移し、車速VSが車速下限値Vmin以下であると判定した場合には(図2(a)中、時刻t2)、エンジン停止処理S180に処理を移す。
差分導出部254は、温度取得部250が取得した触媒120の温度Catが、触媒活性温度Cmin未満であるか否かを判定する。その結果、触媒120の温度Catが触媒活性温度Cmin未満であると判定した場合には減速回生トルク量導出処理S140に処理を移し、触媒120の温度Catが触媒活性温度Cmin未満ではないと判定した場合には当該触媒暖機処理を終了する。
回生導出部252は、ブレーキペダルの踏み込み量と、車速とに基づいて、減速回生トルク量を導出する。
差分導出部254は、バッテリ150の温度と、充電残量と、安全率とに基づいて、上限回生トルク量を導出する。
差分導出部254は、上記上限回生トルク量導出処理S150で導出された上限回生トルク量と、上記減速回生トルク量導出処理S140で導出された減速回生トルク量との差分である差分回生トルク量を導出する。
駆動制御部256は、エンジン110から出力されるトルクを、差分回生トルク量に増加させ、エンジン110から出力されたトルクによってモータジェネレータ140で電力を回生させる。
駆動制御部256は、ECU220を介し、エンジン110を停止させるとともに、モータジェネレータ140で回生トルク量を減少させる。エンジン110の停止に伴って、エンジン110から出力されるトルクの減少に合わせて差分回生トルク量も協調して減少させる。また、エンジン110から出力されるトルクおよび差分回生トルク量がゼロになった後にも減速状態が継続している時にはブレーキペダルの踏み込み量と車速とに応じて減速回生トルク量を導出して、モータジェネレータ140で電力を回生させる。これにより、回生トルク量が徐々に低下することとなる。
