Translation

Abstract(E)This study proposes a predictive battery charging control system for series hybrid electric vehicles using only road gradient information. The system actively uses battery energy during uphill driving to maximize regenerative energy recovery during subsequent downhill driving. A simulation model identified from real-world driving data was used for evaluation on a suburban route with large elevation changes. The results confirmed a significant increase in regenerated energy and an improvement in fuel efficiency, demonstrating the effectiveness of gradient-based predictive control without requiring uncertain velocity predictions.

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.
