적용 범위

This standard applies to M1 and N1 category vehicles as well as multi-purpose trucks. It specifically regulates the design and performance of steering mechanisms to protect drivers from injuries during frontal collisions. It is mandatory for all relevant manufacturers seeking type approval in China.

기술 요구 사항

The standard specifies general and technical requirements for the steering mechanism. In a frontal collision, the backward and upward displacement of the steering wheel support device's top end must not exceed specified limits. For electric and hybrid vehicles equipped with B-class voltage circuits, the high-voltage systems and REESS must comply with electrical safety requirements, including protection against electric shock and electrolyte leakage. During a human body module impact test, the horizontal force exerted by the steering wheel on the module must not exceed a specific limit. If a safety airbag is equipped, it must not generate hard debris towards the occupants during deployment. In a head impactor test, the cumulative duration of deceleration exceeding 80g must be strictly limited, and the maximum deceleration must not surpass 120g. Post-test, the steering wheel surface facing the driver must not present dangerous sharp angles or edges.

시험 방법

The standard outlines three primary testing methods: the Frontal Fixed Barrier Crash Test (evaluating steering column displacement and EV electrical safety), the Human Body Module Test (measuring horizontal impact force), and the Head Impactor Test (measuring deceleration and surface safety). Manufacturers must ensure their products pass all applicable tests.

자주 묻는 질문

What products are regulated under GB 11557-2026?

The standard applies to M1 and N1 category vehicles as well as multi-purpose trucks. It is mandatory for new type approvals starting from the implementation date, with phased deadlines for existing approved models.

Are there any significant updates from the previous GB 11557-2011 version?

The 2026 version introduces updated terminology, including definitions for B-class voltage circuits and REESS. It also modifies the frontal fixed barrier crash test method, updates electrical safety requirements for EVs, and adds provisions for the center of gravity of the human body module and new impact points for the head impactor test.

How does GB 11557-2026 differ from international standards like ISO or ECE regulations?

While the core principles align with international safety practices, GB 11557-2026 incorporates specific Chinese definitions and cross-references other national standards like GB/T 31498 for electric vehicle post-crash safety. Manufacturers must ensure compliance specifically with this GB standard for market access in China.
