ADAS and E/E Architecture: The Frontiers of Software-Defined Vehicles

This White Paper discusses the impact of sensor fusion and perception systems on the electrical and electronic (E/E) architecture of modern vehicles, particularly in the context of advanced driver assistance systems (ADAS). It outlines how these technologies are transforming vehicles into software-defined entities, emphasizing the importance of robust processing capabilities, power distribution, and communication networks. The paper details the differences between object-level and low-level fusion, highlighting the advantages of low-level fusion in terms of reduced power consumption and wiring requirements. It also addresses the implications for E/E architecture, including the need for redundancy, data integrity, and security measures. The document concludes by noting that the choices made by ADAS developers and E/E architects today will significantly influence the future of automotive technology, underscoring the critical role of sensor fusion and perception systems in enhancing vehicle safety and efficiency.
