Abstract(J)本研究では,バッテリの電流波形を用いて車両電子ユニットの動作状況を判定する手法を提案する.バッテリに流れる電流は,複数ユニットの動作電流が重畳した波形となっている.本研究では複数ユニットの電流波形を分割し,特徴点を抽出する事で,微小電流ユニットを他ユニットが動作したまま特定する事に成功した.

Translation

Abstract(E)All electrical component needs to use power from external and makes current wave form at vehicle battery. If battery current wave form can be analyzed exactly, we can compare component operating result and operation request and find abnormally. However, the battery current waveform has complex superposition of many components wave form. So, we used reservoir computing that is one of AI technology and succeed to identify extreme small current component operation in actual vehicle.

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.
