长安汽车10月9日收到中汽中心发送的关于制动踏板总成材质的调研问卷1。作为国务院国资委直属央企，中汽中心受工信部委托发起此次调研1，重点关注非金属材质在踏板总成中的应用情况1。业内人士认为，此举受尊界V800刹车踏板支架断裂事件影响，将有助于推动包括QC/T 788-2018等相关行业标准修订1。
现行强制性国标仅要求车辆最大制动效能时踏板力不超过500N1，而推荐性标准则要求踏板在施加1500±20N压力后需保持5秒、重复5次操作，永久变形幅度不超过5毫米且无裂纹1。现行法规对非金属制动踏板存在标准空白1，导致车企目前各自执行内部标准1。据了解，岚图采用多层高强度钢板主梁设计1，广汽本田雅阁刹车踏板可承受3000N以上压力1，猛士汽车全系制动踏板采用高强度材料且承压能力远超国标1，比亚迪仰望则采用金属材质踏板并执行2500N企业标准1。
Chang'an Automobile confirmed receiving a questionnaire from the China Automotive Technology and Research Center (CATARC) on October 9 regarding brake pedal assembly materials, with particular focus on non-metallic applications 1. The CATARC, a state-owned enterprise directly under the State-owned Assets Supervision and Administration Commission and acting on behalf of the Ministry of Industry and Information Technology, initiated the survey 1.
Industry observers believe the inquiry was prompted by the brake pedal fracture incident involving the Voyah Free V800 and may catalyze revisions to relevant standards including QC/T 788-2018 1. Current regulations contain a standards gap for non-metallic brake pedals, with individual automakers currently implementing their own internal standards 1. Existing mandatory national standards only require that brake pedal force not exceed 500N during maximum vehicle braking 1, while recommended standards specify that pedals must withstand 1,500±20N of pressure for five seconds across five repeated cycles, maintaining permanent deformation of no more than 5mm without cracks 1.
Different manufacturers have adopted varying approaches to brake pedal design. Voyah employs a multi-layer high-strength steel beam structure 1, while GAC Aeon's Accord brake pedal can withstand pressure exceeding 3,000N 1. Mengshi vehicles use high-strength materials throughout their brake pedal systems with load-bearing capacity significantly surpassing national standards 1. BYD Yuan Plus DM-i implements metal brake pedals meeting a 2,500N internal company standard 1.
