Enabling mode changes in a distributed automotive system

Due to the high pressure for innovation, recent cars offer a constantly increasing number of sophisticated functions for advanced driver assistance and an improved active safety. As a result, software complexity in cars rises. Up to now, configurations of current automotive embedded systems are fixed and remain static over the vehicle lifetime. However, this is problematic as all offered functions have to be taken into account for the schedule of currently upcoming time-triggered bus systems and also the OS schedules on the electronic control units (ECUs). In principle, this is not necessary, as subsets of these functions have disjoint phases of use.
