Abstract(J)電気自動車(EV)の普及に伴い,走行中ワイヤレス給電(DWPT)が近年注目を集めている.DWPTを自動運転車両に適用することで無人で無限に走行できる車両が現実できる.この技術を利用する上で重要な課題となるのが,カメラ・LiDAR・GPSなどの外界センサを用いても送電コイルの位置を直接検知できない点である.DWPTでは受電電力とコイルの位置関係には関係がある.そこで,受信側直流電流とビークルダイナミクスを用いて推定した送電コイルの位置を基に,自動運転システム側で操舵制御を行う手法を提案する.

Abstract(E)With the growing popularity of electric vehicles (EVs), wireless power transfer during driving (DWPT) has garnered significant attention in recent years. Applying DWPT to autonomous vehicles realize vehicles capable of driving indefinitely without a driver. A key challenge in utilizing this technology is that lateral misalignment of the coils cannot be resolved even when using sensor fusion technologies—such as cameras, LiDAR, and GPS. Therefore, we propose a method that estimates lateral misalignment based on the DC current at the receiver and vehicle dynamics model, and performs steering correction on the autonomous driving system side.

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.
