Core Viewpoint - The incident involving the Haobo GT vehicle highlights the limitations of L2 level driver assistance systems, particularly in recognizing irregularly shaped obstacles and the failure of the Autonomous Emergency Braking (AEB) system to activate during a collision [1][2][3] Group 1: Incident Details - A video showing a Haobo GT vehicle colliding with a stationary construction vehicle while using Adaptive Cruise Control (ACC) has drawn public attention [1] - The vehicle involved is a 2023 model of Haobo GT 560, which is equipped with an L2 level driver assistance system that lacks lidar and uses a single monocular camera for front perception [1] - The vehicle was traveling at a speed exceeding 80 km/h at the time of the collision, surpassing the speed limit for AEB activation [2] Group 2: System Limitations - The user manual for Haobo vehicles specifies that the system may not function properly under certain conditions, such as when encountering irregularly shaped vehicles or when using ACC with stationary or low-speed vehicles [2] - The AEB system's limitations have been a topic of debate, with various manufacturers facing similar issues regarding the activation speed and response to obstacles [3] - Current AEB systems primarily focus on longitudinal braking and have limited capabilities in recognizing static objects, which raises concerns about their effectiveness in emergency situations [3] Group 3: Regulatory Developments - The recent draft regulations from the Ministry of Industry and Information Technology aim to clarify safety requirements for L2 driver assistance systems, including the use of AEB and lane-keeping functions [3][4] - The new standards emphasize the need for driver assistance systems to effectively respond to foreseeable misuse by drivers and to provide continuous alerts regarding following distances [4] - The upcoming 2025 model of Haobo GT will include configurations with lidar, indicating a shift towards improved obstacle detection capabilities [4]

据悉，该事故车辆为2023款昊铂GT 560后驱七翼版。车辆配置表显示，该车型搭载L2级别辅助驾驶系 统，并未搭载激光雷达，且前方感知的摄像头为单目摄像头。目前，该车型已停售。 对此，昊铂方面表示，经排查核实，上述车辆是1R1V（1个雷达1个摄像头）车，对方目标是防撞工程 车（属于用户手册的异形车，识别局限性），另外施工路段也有说明，在经过十字路口、减速带、陡峭 路面、斑马线或在变换车道、高速公路出入口及匝道或施工路段行驶时，需要退出ACC系统采用全人 工驾驶，以免在这些情况下车辆自动加速到设定车速引发交通事故。昊铂车辆配备的辅助驾驶系统旨在 为驾驶员提供便利的辅助功能，但并非完全自动驾驶。 同时，在昊铂车辆《用户手册》中，已明确提示，在以下情形中，系统的预警及制动功能可能无法正常 工作：1、前方车辆外形不规则时（例如拖拉机、跨斗车等）；2、使用ACC（自适应巡航）时，系统 可能不会对行人、动物、狭窄车辆（如自行车、摩托车、电瓶车）、低架拖车以及低速或静止的卡车采 取制动措施；3、不适用于低矮拖车、卡车或外形特征不规则、不规范的车辆；4、ACC系统在跟车过 程中，可能无法有效识别前方已处于静止或车速接近静止的 ...
