Conclusion & Follow Up Plan
1.背景 Back Ground
Difficult to get full support for MBD from Human resource
director and account director.
MBDを推進するには、ツール購入や人員投入について、リ
ソース管理者の理解が不可欠である。
What’s the best way to establish max powered MBD.
MBDについては、広範に渡っており、どうすれば最大の効果
が得られるかが予測し辛い。
Need to think about joining with not only Development
Division but also Product Div. and Service Div.
開発のみならず、生産やサービスを巻き込む開発形態に発
展させる事も考えられる。
Need to make a relationship between OEMs and
Suppliers at SILS and HILS so on.
装置を使った統合システムを核とした
OEM、サプライヤーの
連携についても論議が必要となっている。

ＭＢＤ
(Model Based Development)とは？
複雑化・高度化した現代の自動車制御システム開発に於て
MATLAB/Simulink
等の
CAEツールによって、
制御装置と制御対象の機能をモデル化
し、それらを
実行可能な仕様書
として用いることで、製品ライフサイクル全般に渡った品質向
上と開発効率向上を目指した開発手法のことである。
シミュレーション技術を駆使することで、高度な機能確認を実施でき、かつ、複雑
な開発工程のルーチンワーク化を促進することで、自動化・省力化にも貢献する。
モデルの定義：対象の機能が図示されており、一意的に解釈できる物

Definition of MBD
MBD: The development style in which
plant and
controller models are used as the executable
functional specifications
.
It is highly expected to encounter the complexity of
automotive control system development. It also
contributes to guarantee the quality of the
products and to realize agile and lean
development.
Model: Simple description simulating the behavior
of an object.
