Abstract(J)従来、熟練したエキスパートが実施しているノッキングのレベル判定作業を機械が判定を行う「ノッキング音レベル判定システム」に置き換えことができた。このレベル判定システムは、マイクからノッキング音を収録し、音データの前処理を実施した後、教師あり機械学習モデルを用いてレベル判定を自動的に行い、社内で定められているレベル基準を表示させるものである。このシステムは、エンジン開発の客観的定量評価と作業時間短縮、さらにはエンジン適合の自動化に貢献できる。

Abstract(E)We were able to replace the conventional knocking level judgment work performed by skilled experts with a “knocking sound level judgment system” in which a machine performs the judgment. This system records the knocking sound from a microphone, pre-processes the sound data, and then automatically judges the level using a supervised machine learning model, and displays the established level standard. This system can contribute to objective quantitative evaluation of engine development, reduction of work time, and automation of engine calibration.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
