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]

Core Viewpoint - The Ministry of Industry and Information Technology (MIIT) is initiating a revision of the national standard for automotive door handles due to safety concerns associated with hidden door handles widely used in electric vehicles. The proposed standards aim to enhance safety features, ensuring that door systems can be opened in emergencies such as power failure or collisions [1][4][17]. Group 1: Safety Concerns - Hidden door handles have been linked to various safety issues, including insufficient strength, potential control logic risks, and difficulties in operation due to lack of visible markings, which can hinder escape during emergencies [4][9][16]. - Incidents have occurred where hidden door handles contributed to rescue difficulties, such as a serious accident involving a Wanjie M7 Plus, where the door handle failed to operate after a high-speed collision, complicating rescue efforts [4][5][6]. - The MIIT's proposed standards will include requirements for mechanical or power failure protection to ensure door systems remain operable during accidents, thereby facilitating rescue and escape [8][9][17]. Group 2: Industry Response - The automotive industry is recognizing the need to shift from a focus on aesthetic and technological appeal of hidden door handles to prioritizing safety. Companies like BYD and Great Wall Motors are actively participating in the development of safety standards [16][17]. - There have been calls from industry leaders to improve the design of hidden door handles to enhance usability in various conditions, including extreme weather [16][17]. - The trend towards hidden door handles has been driven by their sleek design and perceived technological advantages, but the recent focus on safety may lead to a reevaluation of their design priorities [10][11][14].
