Why do we need AUTOSAR ?

Driving Forces

Manage increasing E/E complexity associated with growth in functional scope

Improve quality and reliability of E/E systems

Enable detection of errors in early design phases

AUTOSAR from another angle

must support Component-based

Software Development

for Distributed Systems

Tools

All in all …Model-based Development will be even more encouraged than before !


What is the Status and Roadmap ?

AUTOSAR V3.0 has been released End of 2007and is public now

roughly 10.000 pages of documentation !very sophisticated and complex !

AUTOSAR concepts have been implemented, tested and validated by different vendors

Tools and Basic Software are available !

SOP of first AUTOSAR vehicles expected for 2010-2012
