Abstract(J)運転支援システムの理解度が異なるドライバ群に実路走行でシステムを経験させ、システム受容の違いを主観評定により分析した。システムの挙動限界を教示した群ではシステムへの信頼度が低下した。しかしシステム状態の表示を意識させることで信頼度は回復するとともに、自身のシステム利用状況を自己評価する傾向が現れた。

Abstract(E)Three groups of drivers who were given different explanations respectively about driving support systems (DSS) drove a passenger car equipped with both ACC and LKA on an actual expressway. Drivers’ subjective evaluations showed that mental workload for using DSS increased with detailed explanations of DSS limitations, while explanations of visual and auditory displays for monitoring the DSS status decreased workload. These results suggest influence of introductory explanations of DSS to mental workload, and effectivity of HMI for monitoring DSS status to lighten it.

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.
