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

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

EV Vehicles on the street in the coming yearsWorld wide but especially in China


MC BRS

Almost 20% women

Tricore centre – aver 1/3 of all cars worldwide have tricore chip

Very innovative centre yet small in comparison to worldwide but some highly rated women
