Efficient configuration management of automotive software
Résumé
The need for managing configurations of automotive software is growing significantly as a consequence of the continuously increasing volume of software in vehicles and due to the possibility to exchange software in vehicles over their lifetime. In this paper, we discuss concepts for configuration selection, configuration verification, and configuration update and show an evolution for the step-wise introduction of these concepts to gain an efficient configuration management of automotive software. We propose a configuration model that defines automotive hardware and software releases and describes the dependencies between these releases. This configuration model forms the basis for an update management which enables the download and installation of new software releases into cars to maintain the car's software over its lifetime. We illustrate and discuss a prototypical realization, which takes the proposed concepts into account.
