Collaborative Design Strategies for Electronic and Electrical Architectures in the Intelligent Driving Domain

Abstract

The evolution of intelligent driving technology toward higher levels imposes new demands on electronic and electrical architectures, requiring high computing power, high real-time performance, and high functional safety levels. Traditional development models face challenges such as a disconnect between architecture and functionality, inefficient cross-team collaboration, and lengthy validation cycles. This paper focuses on the intelligent driving domain and establishes a three-tier collaborative design strategy system comprising the application layer, service layer, and hardware layer. Through layered decoupling, it achieves separation of software and hardware as well as standardized interaction between domains; through model-driven approaches, it supports cross-team parallel development; and through digital twins, it advances verification and enhances scenario coverage. A development project for a Level 2+ highway pilot assist function at a certain automaker demonstrates that this framework can shorten the development cycle by 25%, improve validation efficiency by 70%, and achieve a product safety score of 94%, providing a reusable methodological foundation for the development of intelligent driving electronic and electrical architectures.
