摘要

With increasing level of driving automation new requirements regarding reliable power supply for power net components arise. In addition to new fail-operational power nets, appropriate control strategies providing functional power supply at least for the duration of vehicle transition to a safe state (standstill) are required. This paper presents a generic, topology-independent concept for future energy management systems controlling fail-operational power nets for automated driving in both normal and failure cases. Based on predictive runtime energy flow optimization and a 3-level-degradation concept, the energy management system presented in this work allocates the available power net energy resources in a way allowing to bring the vehicle to a standstill at the safest location with the best-suited driving profile and with the maximum of driving comfort. By adapting the control strategy to the current system state, the energy management system enables reliable power supply for power net components and increases the overall energy efficiency.
