Abstract(E)In recent years, societal interest in environmental sustainability has been increasing, and various approaches are being pursued to achieve zero emissions. Despite these efforts, expectations for internal combustion engines remain significant. This study investigates real-world emission conditions using Portable Emissions Measurement Systems (PEMS) and explores countermeasures for emission factors specific to on-road driving. To enable efficient and reliable evaluation and development of emission reduction technologies, a digital twin development environment has been constructed. The traffic flow scenario created by the traffic flow simulation is driven in the driving simulator, and the real car simulator's driving robot reproduces the operations, enabling actual vehicle emission measurement. This paper describes the constructed digital twin development environment and compares the evaluation results obtained from this environment with those derived from on-road emission measurements.

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".
