Zusammenfassung: | To effectively improve the fuel economy performance of an engine.SOLUTION: A control device 100 of an exhaust post-treatment device 40 of an engine 10 mounted to a vehicle 1 comprises: an operation stop prediction part 130 for predicting whether or not an operation of the engine 10 in the operation is stopped; temperature rise control parts 140, 160 for performing temperature rise control for raising a temperature of the exhaust post-treatment device 40 by increasing a fuel injection amount; and reservation interruption control parts 150, 170 for reserving a start of the temperature rise control by the temperature rise control parts 140, 160 when it is predicted that the operation of the engine 10 is stopped by the operation stop prediction part 130, and interrupting the execution of the temperature rise control by the temperature rise control parts 140, 160 when it is predicted that the operation of the engine 10 is stopped by the operation stop prediction part 130 during the execution of the temperature rise control.SELECTED DRAWING: Figure 2
【課題】エンジンの燃費性能を効果的に向上させる。【解決手段】車両1に搭載されたエンジン10の排気後処理装置40の制御装置100であって、運転中のエンジン10が運転を停止するかを予測する運転停止予測部130と、燃料噴射量を増加させることにより、排気後処理装置40の温度を上昇させる温度上昇制御を実行する温度上昇制御部140,160と、温度上昇制御の開始前に、運転停止予測部130によりエンジン10の運転が停止すると予測されると、温度上昇制御部140,160による温度上昇制御の開始を保留させ、温度上昇制御の実行中に、運転停止予測部130によりエンジン10の運転が停止すると予測されると、温度上昇制御部140,160による温度上昇制御の実行を中断させる保留中断制御部150,170とを備えた。【選択図】図2 |
