GB17675-2025《汽车转向系 基本要求》国家认证标准发布 由多家车企联合起草

Core Viewpoint - The new national certification standard GB17675-2025 for automotive steering systems will replace the previous standard GB17675-2021 starting from July 1, 2026, focusing on the safety and functionality of new technologies like steer-by-wire (SBW) and electric power steering (EPS) while removing mandatory requirements for mechanical connections [1][2]. Group 1: Standard Status - The new standard was drafted by multiple automotive companies, including Shanghai Automotive Group, NIO, China Automotive Technology Research Center, Beijing Chehejia Technology, and Guangzhou Xiaopeng Motors [2]. - The revised standard addresses deficiencies in the current requirements for fully powered steering systems, ensuring they meet modern safety and functionality demands [2]. Group 2: Basic Information - The updated standard introduces specific requirements for failure scenarios in fully powered steering systems, including vehicle safety status, degradation requirements, and alarm signals for power source failures [2][3]. - New provisions include real-time monitoring and performance evaluation of energy storage devices, with alarms triggered for aging or insufficient performance to ensure safe operation of fully powered steering systems [3]. Group 3: Additional Requirements - The revision modifies testing requirements for measuring steering control force in the event of system failures and adds additional tests for fully powered steering systems [3]. - The standard also enhances definitions related to fully powered steering systems and introduces requirements for functional safety testing reports and descriptions for electronic control systems [4].
