Compliance overview
Scope and applicability
This standard specifies the technical requirements and type approval criteria for steering systems of motor vehicles. It applies to M, N, and O category vehicles as defined in GB/T 15089. This standard is mandatory for all relevant manufacturers and does not apply to pneumatic steering transmission systems or vehicles equipped with autonomous steering systems.
Technical requirements
The standard mandates that steering systems must ensure ease and safety of operation within the maximum design speed. It specifies requirements for steering control force, self-centering ability, and straight-line driving performance. Additionally, it requires that the steering direction corresponds continuously with the steering control equipment's deflection. For trailers, the standard outlines criteria for straight-line tracking, turning circle radius differences, and swing-out values. In terms of failure provisions, it details the performance requirements for power-assisted steering and full-power steering systems during various fault conditions, ensuring that the vehicle remains controllable and that steering control force does not exceed specified limits. The standard requires clear warning signals (red and yellow) for steering faults, particularly for full-power steering vehicles equipped with an energy management system. Furthermore, it incorporates comprehensive functional safety requirements for steering electronic control systems, aligning with GB/T 34590, including hazard analysis, risk assessment, and safety measures documentation.
Testing methods
The standard outlines testing procedures for both motor vehicles and trailers, including tests for abnormal vibration when leaving a turning circle, steering self-centering ability, and steering control force measurement under normal and fault conditions. It also specifies additional tests for full-power steering systems, such as figure-eight maneuvers and lane change operations to verify performance during power source or energy transmission failures.
