Change

Management

Change management has been put into

action prior to XDIS supporting AUTOSAR

No AUTOSAR methodology implemented

Changes are applied on bus level

Benefits

Long-term experience

Sufficient approach for legacy bus

systems like CAN or LIN

Problems

No holistic system view in Xchange

Steady increasing complexity

Thinking only from a local component

based view

AR Methodology

No AR Methodology

Next Generation In-Vehicle Communication Concepts New Technologies Affect the Way We Design and Manage Communication

Increasing Acceptance of the AUTOSAR Philosophy at Daimler 6

SOME/IP

Signals and frames no longer main anchor for design

process and change management

Configuration is achieved dynamically (SOME/IP)

Describing 1:n communication means describing n

communication paths

Direct links instead of broadcast communication

GW

Application routings prohibit E2E path analysis

Decoupling of domains introduces abstraction in

communication

GW GW GW

Application

Transmission modes and timeout monitoring

have to be done in application

Shift in complexity from COM stack to application

Application

More Abstraction in the Change Management Process Physical vs. Logical Communication

How to provide data on the

source bus by ECU 1?

How to route data on transfer

busses in the best way?

How to guarantee ECU 2

receiving the data in time?

User Group

Consider change requests

from a system view!

Describe the logical data

structure the software expects!

Define the timing requirements

of the software!

Increasing Acceptance of the AUTOSAR Philosophy at Daimler 14

• Provide a combined approach of networking

and system view (use case dependent)

• Take advantage of users’ expertise

• Yet no AUTOSAR in change management

• Insufficient penetration of methodology

• Shift from network to system design

• Consider end-to-end requirements

• Increasing networking complexity

• New communication paradigms

Summary – Lessons Learned Key Success Factors

• Common collaboration platform to reach

users even beyond departmental boundaries

• Comprehensive shared database

• User groups are spread across different

organizational units

• Each having their own focus and knowledge

Challenges Conclusion

Thank you
