Investment Rating - The report does not explicitly state an investment rating for the industry or the company. Core Insights - The automotive industry is undergoing a significant transformation, shifting from a "distributed" to a "domain-centralized" and ultimately to a "central computing + zonal control" architecture. The Zonal Control Unit (ZCU) is identified as a key node in this evolution, marking an important step towards industry intelligence [9][10]. Summary by Sections 1. Traditional Architecture Constraints: The "Impossible Triangle" of Intelligent Transformation - The traditional distributed electronic architecture faces challenges in balancing computing power and cost, functionality and safety, and innovation and inertia, leading to inefficiencies [12]. - The traditional architecture results in over 100 Electronic Control Units (ECUs) in high-end vehicles, creating "information silos" and inefficient computing resource allocation, which increases costs and complexity [13]. - The lengthy development cycles of 3-5 years for new features hinder the automotive industry's ability to respond quickly to market changes [13]. - The architecture's limitations restrict innovation, as Tier 1 suppliers dominate ECU function development, making it difficult for manufacturers to achieve product differentiation [14]. 2. Architectural Innovation: The Necessity and Core Value of ZCU - The automotive industry requires a comprehensive overhaul of its architecture, with the "central computing + zonal control" model seen as a future solution, where ZCU plays a pivotal role [17]. - ZCU simplifies wiring, reduces costs and weight by consolidating local wiring through a high-speed Ethernet backbone [17]. - It enables hardware standardization and software decoupling, providing a foundation for "software-defined vehicles" [17]. - ZCU supports centralized power management, enhancing energy efficiency and replacing traditional fuse and relay boxes [17]. 3. Systematic ZCU Solutions by the Company: Implementation Path for Architectural Reconstruction - The company's ZCU solution addresses the computing power and cost paradox, innovation inertia, and functionality and safety challenges, providing a clear path for automotive companies to reconstruct their architectures [19]. - ZCU integrates various control functions within specific physical areas, significantly reducing the number of ECUs and wiring complexity [21]. 4. Market Leadership: Million-Unit Deliveries and Industry Benchmark Status - The company has delivered over one million ZCUs, achieving the highest market share in China, marking a significant milestone in the industry's acceptance of the zonal control architecture [51][52]. - The rapid production timeline demonstrates the maturity of the ZCU technology and its role in the transition to next-generation electronic architectures [55]. 5. Future Directions: Evolution Path of ZCU Technology and Industry Collaboration - The ZCU's strategic importance will continue to grow as the automotive electronic architecture evolves towards "central computing + zonal control," with trends towards standardization and platformization [57]. - The company actively participates in industry standard-setting, promoting collaborative development and resource efficiency [58].
