Core Viewpoint - The new national standard for automotive steering systems, GB17675-2025, will be implemented on July 1, 2026, marking the second revision since its initial release in 1999. This standard aims to adapt to the rapid advancements in electric and intelligent vehicles, particularly in steering systems transitioning from mechanical to drive-by-wire technology [2][3]. Group 1: Standard Implementation and Industry Impact - The new standard clarifies technical requirements and testing methods for steering systems, mandating dual communication and power supply redundancy for drive-by-wire systems, which will lower R&D and collaboration costs across the industry [3][4]. - The removal of the requirement for mechanical connections in steering systems allows for the legal and large-scale sale of drive-by-wire vehicles in China, providing a foundation for the commercialization of new technologies [3][5]. - The standard's upgrade reflects the changing market demands and is a significant regulatory breakthrough for China's automotive industry amid the trends of electrification and intelligence [3][5]. Group 2: Technological Advancements and Safety Requirements - The new standard introduces failure degradation, alarm, and functional safety requirements for drive-by-wire systems, establishing clear safety boundaries for these technologies [4][5]. - The transition to drive-by-wire technology is seen as a critical step towards commercial viability, addressing the legal and safety concerns that have previously hindered its adoption [5][6]. - The standard emphasizes the need for energy management systems and detailed functional safety requirements, which will standardize the development and evaluation processes for drive-by-wire products [5][6]. Group 3: Market Trends and Future Directions - The commercialization of drive-by-wire technology is expected to begin with mid-to-high-end vehicles, gradually penetrating lower segments as costs decrease due to industry maturation [9][10]. - The integration of drive-by-wire systems with other technologies, such as brake and suspension systems, is anticipated to enhance the performance and safety of intelligent driving solutions [9][10]. - The evolution of steering systems is projected to lead to a more flexible and efficient vehicle design, with the potential for significant cost reductions as the technology matures and scales [10].
