#3: Software
Software
Hardware
1980 1990 2000 2010
 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

11. 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
Steering Angle Sensor 8 bit microcontroller 7 Bugs* 32KB Code
ABS Controller 16 bit microcontroller Bugs* 128KB Code
