The unique structure and innovative drive mode of distributed electric drive vehicles can significantly enhance overall vehicle performance, making them a crucial direction for the future development of electric vehicles. The application of distributed electric drive vehicles has greatly promoted technological innovations in high-performance vehicles. It not only improves energy efficiency, driving safety, and maneuverability but also provides new solutions for specialized applications such as the road transportation of oversized and heavy-haul cargo. This paper reviews the century-long evolution of vehicle configurations and highlights the inevitability of the development of distributed electric drive architectures in the context of vehicle electrification and intelligence, as well as the profound transformations they bring to the automotive industry. The paper conducts a comprehensive analysis of the core technologies of distributed electric drive vehicles worldwide, identifying key challenges in their current development. Finally, the paper presents an outlook on the field, proposing future development goals and technological transformation directions for distributed electric drive vehicles, with the aim of providing scientific insights and strategic recommendations for advancing research and application in China.

As the automotive industry accelerates its transformation towards intelligence, electrification, sharing, and connectivity, traditional reverse engineering development models have proven inadequate for addressing the demands of complex functional integration and new vehicle configurations. Forward vehicle design has consequently emerged as a critical pathway for driving technological innovation. This paper systematically reviews the evolution of automotive design methodologies, technological breakthroughs, and key challenges. It highlights the advantages of the traditional V-model development process in performance balancing and styling design. However, intelligent vehicle design employs model-based systems engineering methods to achieve deep interdisciplinary integration and optimizes virtual-physical collaborative design through digital twin technology, thereby significantly improving development efficiency. The paper identifies that software-defined vehicles, modular flexible design, and distributed electric drive technologies have driven innovation in chassis configurations. Notably, integrated design has demonstrated significant results in the fusion of structure, safety, and cabin driving. Nevertheless, key bottlenecks remain, including the complexity of technological integration, the lag in dynamic modeling theory, and the underdeveloped domestic industrial software ecosystem. To address these challenges, the paper proposes the establishment of an innovative system for vehicle forward design centered on model-based systems engineering. It further advocates for strengthening unified dynamic modeling and multi-objective collaborative control theories for modular re-configurable vehicles. Additionally, the paper calls for greater collaboration among government, industry, academia, and research institutions to break through core industrial software technologies, thus enhancing the domestic computer-aided design tool chain ecosystem and advancing technological innovation within the automotive sector.
