• Middleware
• Re-use of software components
• Interoperability of software components
• Perspectives
• Software as independent component from
  tentatively new suppliers?
• Component Library
• Flexible integration of software components
• Reduction of development effort and time
• Challenges
• Similar activitiesz.B. AEE, Titus, EUCAR-WGs
  (1999, 2000)
• non-coordinated efforts let to variant explosion
  at the suppliers
• Harmonization indispensable

4 Conclusions and Future Work

• EAST-EEA
• Design of a middleware based architecture for
  networked ECUs
• Architecture Description Language
• Specification of middleware (domain oriented)
• Lab-Validators (Body-Electronics, Chassis, ...)
• 23 Partners Vehicle Manufacturers, Suppliers,
  Tool-Provider, Research-Institutes
• Documents results available by July 04
• Feedback from daily work
• Basis for future standardization activities
  (OMG, Autosar)
