Abstract(E)To achieve a carbon-neutral society, improving hybrid vehicle fuel efficiency is essential. This study developed a 1D thermal model enabling thermal flow design of the drive unit based on vehicle system performance. The model accurately simulates internal heat behavior and supports design guidelines aligned with overall vehicle performance. Using this model, specifications were designed and validated through hybrid unit testing, confirming predicted fuel efficiency. This approach offers a new method for fuel efficiency improvement starting from thermal design and is expected to be effective in future electrified vehicle development.

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.
