Abstract(E)Hands-off function of driver assistance system is expected to have an effect on driver’s workload reduction of cognition, judgement and operation. In this study, effectiveness of the hands-off function was examined through a field test of highway driving. The experiment revealed the effectiveness from the aspect of driver’s subjective fatigue and effort, heart rate variability as an index for mental workload, and muscular activity as an index for physical workload. Furthermore,in the use of driver assistance system, a model of workload factors and their structure was shown, which included contribution ratio of each factor.

About search


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.
