State-based power optimization using mixed-criticality filter for automotive networks

In this paper we propose an approach on energy management for optimizing the energy consumption of both electrical and conventional vehicle´s board electronic. The pursued idea exploits degrees of freedom resulting from vehicle functions which are not permanently used during operation. The elaborated framework achieves this by a state-based power optimization approach using partial networking. It selectively shuts down Electronic Control Units (ECUs) based on requirement and criticality. Experimental results show up to 29.6% saving of the ECUs energy consumption on several driving cycles, which were created from real measured data provided by an automotive OEM.
