The optimization of the electronics architecture of the vehicle
requests flexibility in introducing new functionalities at a
competitive cost. Within a consortium project called "Embedded
Electronics Architecture,'' two car manufacturers: Renault
and PSA, Aerospatiale, three tier 2 suppliers: Sagem, Siemens and
Valeo, three R&D labs: INRIA, IRCyN and Loria have joined their
R&D efforts. The partners define a fast and reliable process
for designing the system architecture, developing the associated
embedded software, selecting the appropriate hardware and software
allocation, defining and integrating reusable components. The
development process is based on independence between hardware and
software, standard components, development methods and tools,
contactualization of the development issues between partners.
The paper will introduce the consortium activities, the
technical approach and give the first results: Architecture
Implementation Language(AIL), interface , standardiza-tion,
development methodologies.
