Das Potential für ein effektives Energiemanagement in Kraftfahrzeugen ist stark abhängig von der Partitionierung der verschiedenen Fahrzeugfunktionen auf die verteilte Steuergerätearchitektur des Fahrzeugs. Im Rahmen dieses Beitrags werden die Auswirkungen von verschiedenen Partitionierungsaltemativen auf das Energiemanagement und die möglichen Energieeinsparungen evaluiert. Mit Hilfe eines selbstentwickelten Simulationsframeworks können energetische Aspekte von E/E-Architekturen während eines Fahrzyklus ausgewertet werden.
The potential for effective E/E power management in automotive systems is highly dependent on the partitioning of the various vehicle functions on the distributed electronic control units architecture. Based on a system model, the impact of different partitioning variants on the power management and the potential power savings are presented in this paper. The evaluation framework is built around a custom simulation tool for analyzing energetic properties for E/E architectures being exposed to arbitrary driving cycles. This paper discussed by means of an exemplary use-case the potential of different power management concepts in respect to partitioning alternatives. The simulative evaluation showed that the power savings due to temporarily switching off unused functions or ECUs (electronic control units) is highly dependent on the deployment of the various vehicle functions. Our analysis showed that for the given use-case, dynamic power management can yield power saving in the range of up to 14%.
