A Survey on the State and Future of Automotive Software Release and Configuration Management

Sax, Eric; Reussner, Ralf; Guissouma, Houssemeddine; Klare, Heiko

Abstract:
In modern vehicles, embedded software is mainly the driving force for the realisation of new functionality. Spread on more than hundred electronic control units, software parts work together in a network to fulfil certain tasks of safety, comfort, energy management and of course vehicle dynamics. Currently, this software is flashed at the end of the assembly line. In regular terms (normally six months), a software baseline of all the electronic control units is released. As a consequence, a distinct variety of releases is deployed on vehicles on the road for each vehicle type. Combined with the alternatives of engines, chassis and customer wishes, the variants of vehicles rise to a number beyond millions. Opening now the chance for over the air updates demands for restrictive and rigorous consistency checks before any update is spread among all the vehicles of one brand or type in the field. In an empirical study based on a survey, we collected and interpreted the answers of participants from different automotive institutions concerning the current state of practice and the faced challenges during release development and management. ... mehr
