Description
<システム全体構成>
図1は、本実施の形態に係る車両管理システムの全体構成を概略的に示す図である。車両管理システム100は、車両1Aと、複数の車両1Bと、管制センタ2とを備える。図1には車両1Aが給油所9にて給油される様子が図示されている。車両1Aは、本開示に係る「対象車両」に相当する。
図3は、エンジン3の構成の一例を示す図である。エンジン3は、たとえば直列4気筒型の火花点火式の内燃機関である。エンジン3は、エンジン本体31を含む。エンジン本体31は、一方向に並べられた4つの気筒311~314を含む。各気筒311~314の構成は同等であるため、以下では気筒311の構成について代表的に説明する。
図5は、センサ類4の構成の一例を示す図である。センサ類4は、車速センサ401と、アクセル開度センサ402と、エンジン回転速度センサ403と、ノックセンサ404と、エアフローメータ405と、スロットル開度センサ406と、筒内圧センサ407と、冷却水温センサ408と、過給圧センサ409と、過給温度センサ410と、タービン回転速度センサ411と、排気温度センサ412と、空燃比センサ413と、NOxセンサ414と、差圧センサ415とを含む。
車両1Aの燃費向上およびドライバビリティ向上を実現するためには、エンジン3の燃焼状態を改善することが望ましい。車両1Aが燃料の組成情報を取得し、その組成情報を基にエンジン3の燃焼状態を改善することも考えられる(たとえば特許文献1参照)。しかしながら、燃料の組成情報を求めるには燃料の解析等の複雑な工程が必要となり得る。そこで、本実施の形態においては、燃料の組成情報を利用する構成に代えて、以下に説明する構成が採用される。
図6は、本実施の形態におけるエンジン3の燃焼状態に関する予測モデル(燃焼予測モデル)の一例を示す機能ブロック図である。燃焼予測モデルは、センサデータおよび給油所データを受けると、センサデータおよび給油所データが指し示す指標を特徴量として、機械学習により得られた演算規則に従って補正量を出力する。
図7は、エンジン3の噴射系の動作を補正するための燃焼改善処理の一例を説明するための図である。図7および後述する図8~図10において、横軸はエンジン3のクランク角を表す。縦軸はエンジン3の気筒311~314の筒内圧を表す。
図11は、本実施の形態における燃焼改善処理の処理手順を示すフローチャートである。このフローチャートに示される処理は、予め定められた条件成立時(たとえば、車両1Aの走行中などのエンジン3の動作中に所定の制御周期毎)に実行される。図中左側には車両1Aにおいて実行される処理を示し、右側には管制センタ2において実行される処理を示す。各ステップは、車両1A(ECU13)または管制センタ2(サーバ23)によるソフトウェア処理により実現されるが、ECU13またはサーバ23内に配置されたハードウェア(電気回路)により実現されてもよい。ステップをSと略す。
