LI AUTO(US:LI) 自动驾驶之心·2025-11-07 00:05Core Insights - The article discusses the advancements in autonomous driving technology, particularly focusing on the transition from data closed-loop systems to training closed-loop systems, marking a new phase in autonomous driving development [18][21]. Group 1: Development of Ideal Auto's Intelligent Driving - Ideal Auto's intelligent driving has evolved through various stages, from rule-based systems to AI-driven E2E+VLM dual systems and VLA, with a strong emphasis on navigation as a key module [6]. - The current end-to-end mass production version of MPI has reached over 220, representing a 19-fold increase compared to the version from July 2024 [13]. Group 2: Data Closed-Loop Value - The data closed-loop process includes shadow mode validation, data feedback to the cloud for mining, automatic labeling of effective samples, and model training, with data return achievable in one minute [9][10]. - Ideal Auto has accumulated 1.5 billion kilometers of driving data, utilizing over 200 triggers to produce 15-45 second clip data [11]. Group 3: Transition to Training Closed-Loop - The core of the L4 training loop involves VLA, reinforcement learning (RL), and world models (WM), optimizing trajectories through diffusion and reinforcement learning [23]. - Key technologies for closed-loop autonomous driving training include regional simulation, synthetic data, and reinforcement learning [24]. Group 4: Reconstruction and Generation Work - Ideal Auto has made significant progress in reconstruction and generation, with multiple top conference papers published in the last two years [28][32][34]. - The generation applications range from scene editing to scene migration and scene generation [36]. Group 5: Interactive Agents and System Capabilities - The development of interactive agents is highlighted as a critical challenge in the training closed-loop [40]. - System capabilities are enhanced through world models providing simulation environments, diverse scene construction, and accurate feedback from reward models [41]. Group 6: Community and Collaboration - The article mentions the establishment of nearly a hundred technical communication groups related to various autonomous driving technologies, with a community of around 4,000 members and over 300 companies and research institutions involved [50][51].
