Expected Revolution of Vehicle Architecture
Convergence of Systems
Improve In-vehicle network with increased bandwidth and higher determinism with backbone.
We cannot have one more ECU every time we add a new function
Increase Car ElectrificationHigh Voltage, High Power
Partitioning by application “Domain”
Partitioning by location
Grouping of functions
2015: Domain architecture connected via backbone

The Paradigm shift from Hardware to Software
Vehicle’s “Drive & Feel” will become increasingly defined by algorithms and software i.e. SW will become a significant element in brand differentiation!
The amount of software will increase significantly
Software complexity increases and will be a compilation of different vendor’s contributions

Software Testing: Discovering the Bugs You can’t write software without introducing bugs!
After initial coding you can expect one bug per 20 lines of code
After thorough unit testing you can expect 1 bug per 1000 lines of code in the final release
1 line ~5 bytes, so 1 bug per ~5KB
