Abstract(E)	Although accidents caused by drivers’ physical condition account for only a small percentage of all traffic accidents, they are highly likely to lead to serious accidents if they do occur, so speedy actions from both product and social rule aspects are desirable. In response, many companies have developed and commercialized emergency stop assist system which stops in the lane, and also the development and discussion of emergency stop assist systems with pull-over function is being promoted in several countries in order to ensure the safety of the own vehicle, the following vehicle, and the evacuation of passengers, and to shorten the rescue time. Regarding Advanced Driver Assistance Systems (ADAS) in the market, the ones which are categorized as Lv.2 by SAE are mainstream, so the development of emergency stop assist systems with pull-over function that utilize Lv.2 ADAS is required in order to spread the use of it. In this paper, we describe the basic design and concept of an emergency stop assist system using Lv.2 ADAS which is based on the premise that the driver must be appropriately involved to ensure safety. This paper also describes an approach to increase the acceptability of the emergency stop assist system by switching between pull-over and stop-in-the-lane according to the situation, and also discusses the technology for judging whether the driver is abnormal or not in the Lv.2 ADAS system in a system that allows hands-off operation under certain circumstances, and the notification to surrounding vehicles in consideration of regional characteristics.

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.
