Abstract(J)車載電子部品の高機能化や車両の意匠,使われ方の多様化により搭載位置に応じた電子部品の熱設計がより重要になっている.車室内温度を予測するため,本稿では第1報で提案した手法を第1報とは異なる車種,地域に適用し,実測と比較することで本手法が有効となる境界条件の検証及び温度変化量誤差の改善に取り組んだ.

Translation

Abstract(E)With the enhancement of functionalities in automotive electronic components and the diversification of vehicle designs and applications, the thermal design of electronic components based on their installation positions has become increasingly critical. To predict the temperature within the cabin, this paper applies the method proposed in our first report to a different vehicle model and region, and compares the results with measurements to validate the boundary conditions under which the method is effective and to improve errors in predicted temperature variations.

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.
