广汽获批L3有条件自动驾驶高速道路研发测试 最高测速120km/h

Core Viewpoint - GAC Group's Haobo brand has officially launched L3 conditional autonomous driving highway research and testing for the A800 model, with a maximum testing speed of 120 km/h, approved by relevant authorities in Guangzhou [1] Group 1: Industry Context - The distinction between the responsibilities of combined driving assistance and conditional autonomous driving is becoming increasingly clear, with most mainstream models operating at L2, where the driver bears responsibility. L3 represents a significant shift, as the system will take on the primary driving tasks in limited scenarios [3] - Highways present a challenging environment for L3 due to the compressed decision-making and execution time at speeds of 120 km/h, along with complex situations such as construction, accidents, and frequent lane changes [3] Group 2: Technical Approach - GAC employs a systematic approach in the development of the A800, centered around its self-developed Xingling Safety Guardian system, in deep collaboration with Huawei to create a complete technical loop for highway L3 conditional autonomous driving [5] - The vehicle features a 360-degree all-weather perception matrix that integrates multiple sensors to provide stable environmental information for highway scenarios [7] - The system aims for millisecond-level parallel judgment and precise control at high speeds, leveraging Huawei's Qian Kun Intelligent Driving ADS4 for computational power and algorithms [7] - Redundant designs in key areas such as perception, computation, steering, and braking ensure that the system can safely operate or smoothly take over in case of single-point anomalies [7] Group 3: Development Stage - Conducting high-speed tests at 120 km/h signifies that the system must complete full-process verification within the mainstream speed range, marking a transition from engineering development to a verifiable and regulatory phase [9] - The development of autonomous driving technology is a long-term endeavor, and GAC will continue to focus on verification work in real road scenarios, gradually advancing the maturity and application of L3 conditional autonomous driving technology [9]
