Abstract(J)本稿では,Mazda Co-Pilot Concept の実現に向けた潜在的危険の予測技術として,他車の車線変更予測と歩行者,自転車の飛び出し予測について説明する。従来の車線変更予測では,予測対象とする他車の予備動作や周辺車両との車間距離から,車線変更を予測してきた。本研究では,予測対象が車線変更を決断する車間ギャップのモデルを応用することで,実際に車線変更を行う2.0 秒前の予測が可能となり,他車の横方向からの衝突を回避可能とする目途が付いた。また,飛び出し予測では環境の危険度を予測する先行研究があるが,飛び出す対象が分かっている必要があった。そこで本研究では,飛び出すのが歩行者か自転車かを一方通行やビルの壁,歩道の有無などの環境特徴から予測する技術に取り組んだ。今回,統計的に説明できるようモデル化の検討を進めることで,環境特徴が歩行者,自転車の行動に影響を与えることが明らかになった。

Abstract(E)We have worked on developing the technology to predict potential risks, aiming for realizing Mazda Co-Pilot Concept. In this paper, we describe the prediction of lane changes and run-out of pedestrians or cyclists. In the prediction of lane change, we applied a model of the gap between vehicles where a prediction target decides to change lanes. By adjusting the parameters to the prediction target while driving, we achieved a prediction time faster than the target of 2.0 seconds. In the prediction of run-out, it is required to identify what the target is, according to the previous research to predict risks on environment. In order to make e ective use of the research, we worked on a technique to predict whether the target of run-out is a pedestrian or a bicycle based on environmental features. By developing a model that can explain the prediction statistically with factual data, it became clear that environmental features influence the behavior of pedestrians and cyclists.

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
