Abstract(J)将来のカーボンニュートラルなモビリティへの移行に伴い,電動パワートレインによる更なるソリューションが期待されている.効率,適応性,可変性,そして快適性といった電動パワートレインに対する高い要求は,無段変速機(CVT)に注目を向けさせることになる.なぜなら,CVTは高い車両性能を実現しながら,電動機を効率良い作動点で駆動することができるためである.本文では,電動パワートレインに最適化されたCVTを用いたソリューションを紹介し,Cセグメントから小型商用車までをカバーするモジュール化CVTの設計を提案し,KPIの改善とさらに広い可能性により,CVTは将来の電動パワートレインに貢献できることを紹介する

Abstract(E)With the transition towards more climate-neutral mobility of the future, a further electric powertrain solutions is expected. Crucial requirements such as efficiency, adaptability, variability and comfort make the continuously variable trans-mission(CVT)interesting to look at. It supports a more energy-efficient use of electric motors, while providing the high vehicle performance level. This study presents optimized electric CVT solutions. A modular CVT design for electrified powertrains is proposed that covers the C-segment all the way to light commercial vehicle segments. KPI improvements and wide variety of possibilities make CVT a valuable contribution to a future of electric powertrains.

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.
