Analysis of Update Capabilities of Modern Automotive Electric/Electronic Architectures

The automotive industry is experiencing a rapid evolution in Electric / Electronic (E/E) architectures to meet increasing functional demands. Meanwhile, frequent software updates are crucial for bug rectification and feature augmentation. However, the impact of E/E architectures on software update efficiency, range, and cost has not been adequately addressed. This paper examines automotive E/E architectures from a layered perspective and employs a software update use case with simulation to assess their influence. The results highlight the potential for improving software update efficiency through centralized E/E architectures and offer insights into optimizing future E/E architectures.
