汽车视点丨机动车安全新规征求意见：百公里加速不少于5秒、电池报警后5分钟不起火、强制标配机械门把手

Core Viewpoint - The newly released draft of the national standard "Technical Conditions for Motor Vehicle Operation Safety" addresses critical issues related to electric vehicles, including battery safety, intelligent driving assistance, and mechanical door handles, with a focus on enhancing vehicle safety standards [1][2][4]. Group 1: General Safety Requirements - The draft introduces key quantitative indicators applicable to all vehicles, such as a default acceleration time of no less than 5 seconds for passenger cars after ignition to prevent rapid starts [2]. - It establishes a "brake signal priority" principle, ensuring that the vehicle control system prioritizes braking over acceleration in conflicting signals, thereby reducing operational risks [2]. - For intelligent features, the draft mandates that displays must be turned off and entertainment functions prohibited when the vehicle speed exceeds 10 km/h, and driving assistance systems must continuously monitor the driver's status [2][3]. Group 2: Specific Requirements for Electric Vehicles - The draft imposes stringent controls on battery thermal runaway risks, requiring real-time monitoring and warning capabilities for battery units, with audible and visual alerts for detected thermal events [4]. - It sets a safety benchmark for large electric buses, mandating that the battery compartment must not catch fire or explode within 5 minutes after an alarm, providing critical escape time for passengers [4]. - The draft also specifies physical protective structures for battery packs and requires vehicles to automatically disconnect power circuits in severe collisions [4]. Group 3: Post-Accident Safety Measures - The draft emphasizes the importance of passive safety design, introducing new regulations to maximize occupant safety and facilitate rescue after an accident [5]. - It requires vehicles to have mechanical door handles that can be operated without external tools, ensuring doors can be opened even if electronic locks fail after a collision or thermal event [6]. - Additionally, it mandates the inclusion of an emergency rescue manual in vehicles to provide rescue personnel with quick access to critical information, enhancing the efficiency of post-accident rescue operations [6]. Group 4: Industry Implications - The draft is noted for its forward-looking approach to technological advancements and systematic requirements, aiming to elevate proven intelligent driving assistance technologies to universal safety standards [6]. - It directly addresses the safety concerns surrounding electric vehicles, establishing a comprehensive framework for monitoring, warning, delaying, and protecting against risks, thereby setting quantifiable safety thresholds [6]. - The implementation of these standards is expected to drive automotive manufacturers and component suppliers to optimize product designs, ultimately enhancing vehicle safety from the source [6].
