Abstract(J)安全なレベル3自動運転の実現に必要な運転交代可否判断の指標として構築した、交代時間を視行動から推定するモデルの検証のため、余裕がある状況を含むシーンでの実験をシミュレータと実車で実施した。その結果、交代直前のハンドル把持とシーンの余裕時間をモデルに加えることで交代時間を概ね推定できることを確認した。

Translation

Abstract(E)In level 3 autonomous driving, the driver is required to take over the driving within a certain time if necessary. In this paper, we validate readiness estimation model which we developed. This model estimates driver’s reaction time from take-over requests, which is based on gaze behavior of the driver. The validation experiments are performed with both a driving simulator and actual vehicle. In the experiments, we measured a reaction time in some situations including larger and smaller time margin. As a result, we have confirmed validity of the models which is appended driver hands-on situation and take-over time margin.

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.
