Abstract(E)	The vehicle architectures for SUV and LD-BEVs come with higher performance requirements, which can no longer be supported by single speed architecture A highly efficient 2speed e-Axle featuring single dry-clutch transmission and utilizing high-speed E-machine is the right answer to fulfill future needs for this segment By increasing the maximum E-machine speed enables potential for further size reduction. Highly efficient cooling concepts are the key to fulfill the customer expectation on high efficiency and performance repeatability New simulation methods are required to obtain an optimized overall efficiency, NVH, thermal behavior and durability already in early stage of the e-Axle development

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
