• Looking at the design of ECU´s:
– Standardize network management
functions and communication services in
different domains to reduce software
development costs:
- First step to an open system design

Autosar Standardization
• The goal of the Autosar process:
– Virtual, independent description of ECU´s, SW-components and
system constrains
– Mapping of software to hardware depending on quality factors
and system constrains

Autosar and OSGi Technology
• OSGi is execution environment for a single device to
support a standard deployment model
• Autosar is a distributed environment, static after
generation, designed for multi-language use and
supports hard real-time. Autosar defines a process for
system creation

Usage ResellOrder Production Delivery
• Independent SW/HW-development process:
Supplier independence, reduced costs, increased
flexibility
• Software-Upgrades after production for long-term,
simplified maintenance
• Remote Diagnostics
• SW-Update/Upgrade before resale
• Software-based option for vehicle individuali-zation
and customer personalization in production, on
dealer level or via E2E-service chain delivery:
“Software as a Product”

SW Download - Challenges
• Enable seamless software-development process
(Supplier, OEM, Third-Party)
– Model-Based Development
– Integrated Product-Data and SW-Configuration-Management
– Change-Management / Control Compatibility / Testing
– Security Infrastructure, graduated Firewall-Concept (AA),
Certification Mechanism for Software and HW

Open Platform Beyond The Vehicle
• National scope
• European harmonization
• National scope
• Open service delivery platform
• Harmonized access network profiles
• Protocol standardization
• Open, but secure runtime environment
• User interface
• Vendor-independent minimum vehicle access
• Interface and platform standardization

Wrap Up
• Trend to concentrate functionality in service platforms
and to reduce the number of ECU´s
- OSGi Standard is an enabling technology !
• The automotive industry is changing to an industry
mainly driven by electronics and SW:
- new development process
- match this to organizational structure
• SW-Download offers a lot of opportunities
• Standardization is an important issue
• BMW is addressing this issues in different
standardization activities and projects
