Model-based Analysis & Engineering of Novel Architectures for Dependable Electric Vehicles

Purpose: Refine EAST-ADL Language, tools and methodology to support Electrical Vehicle development

MAENAD Overview. Henrik Lönn, Volvo Technology 9

Motivation

Electrical Vehicle development and ISO 26262 require adequate engineering support

Collaborative character of automotive industry makes standards necessary also for specifications

MAENAD Overview. Henrik Lönn, Volvo Technology 10

Objectives

Refine EAST-ADL Language, Tools and Methodology toAssist the safety process defined in the ISO 26262 safety

standardProvide effective prediction of quality attributes

(dependability and performance) Provide tool support for the automated

exploration of design spaces(dependability, performance and cost optimization).

Finally…

A Specification is a core asset – Shall not be tool specific EAST-ADL is an open, AUTOSAR-compliant representation for

specifying embedded systems Shared ontology/terminology across companies and domains EAXML exchange format to secure tool interoperability Allows joint efforts on methodology, modelling and tools

Supports several aspecs (timing, variability, behavior, V&V, etc. through extensions)
