Tobias Kain, Philipp Mundhenk, Julian-Steffen Müller, Hans Tompits, Maximilian Wesche, Hendrik Decke, Jyotirmoy V. Deshmukh, Sebastian Steinhorst
2020 Design, Automation, and Test in Europe  
Our approach defines three interconnected layers, which are distinguished by their level of awareness. The top layer, referred to as the context layer, is responsible for observing the context.  ...  These context observations, in turn, imply a set of requirements, which constitute the input for the reconfiguration layer.  ...  Since the advance of autonomous vehicles is imminent, further work concerning each layer of our approach for context-based system architecture is necessary.  ...
