ABSTRACT

AUTOSAR (AUTomotive Open System ARchitecture) is an open industry standard for the automotive sector. It defines the three-layered automotive software architecture. One of these layers is the application layer, where functional behaviors are encapsulated in Software Components (SW-Cs). Inside SW-Cs, a set of runnable entities represents the internal behavior and is realized as a set of tasks. To address AUTOSAR’s lack of support for modeling behaviors of runnables, languages such as Simulink are employed. Simulink simulations assume Simulink block behaviors are completed in zero execution time, while real execution requires a finite execution time. This timing mismatch can result in failures to detect unexpected runtime behaviors during the simulation phase. This paper extends the Simulink environment to model the timing properties of tasks. We present a Simulink block that can schedule tasks with non-zero simulation times. It enables a more realistic analysis during model development.

AUTOSAR (AUTomotive Open System ARchitecture) は、自動車分野の公開業界標準です。三層の自動車ソフトウェア構造を定義しています。一つは応用層です。機能的な振る舞いをソフトウェア要素 (SW-C) に包み込みます。 SW-C の内部では、Runnable実体集合内部動作を表し、task集合として実現します。 AUTOSAR ではRunnableの振る舞い模型に対応していないために、Simulink などの言語を採用しています。 Simulink模擬試験では、Simulink blockの動作は実行時間ゼロで完了することを前提としています。実際の実行には有限の実行時間が必要です。この時間の不一致により、模擬試験段階で予期しない実行時の振る舞いを検出できない可能性があります。この論文では、taskの時間特性模型を作成し Simulink 環境を拡張します。ゼロ以外の模擬試験時間でtaskを計画できる Simulink blockを紹介します。模型開発中により現実的な分析が可能になります。
