The e/e (electric/electronic) architecture of a modern vehicle consists of a complex distributed network of electronic control units (ECUs) interconnected by various communication buses. The electrical power consumption of the overall systems is not negiectable anymore since it negatively affects the fuel consumption and CO2 emission of a vehicle. The electrification is further increasing with every vehicle generation and energy efficiency is becoming one of the main design goals. In this paper a prototypical hardware test bench is presented that can be used for the evaluation of e/e architectures with respect to energy efficiency. Different power management techniques can be implemented and compared with each other. Experimental results indicate the potential power consumption savings for different test scenarios and the effects of the function partitioning on the overall power consumption.
