Control variant-rich models by variability measures
Stefan Mann, Georg Rock · 2011
The embedded systems market and especially the software part of it is growing drastically in automotive industry. Today we see that the value of software or functionality that is realized using software within cars is about 35% of the value of the car itself. We have typically more than 70 embedded control units (ECUs) in a car with functionality realized and controlled by software. The standardization of communication interfaces and operating system functionality as for example realized by AUTOSAR facilitates the distributed development of software. But the needs to produce software in time and in budget remain still a main task in automotive software industry. To cope with tight project plans, process models based on product line technology promise a good chance to be successful. Nevertheless, the need to control the product development remains still one of the most important questions in this area.
