Champ d’application

This standard establishes the requirements and measurement methods for the direct forward visibility of drivers within a 180-degree range. It is mandatory for M1 (passenger cars) and N1 (light commercial vehicles) category automobiles. Manufacturers of light-duty vehicles must ensure their windshield designs, A-pillars, and dashboard layouts comply with these specifications. It does not apply to heavy-duty vehicles or specialized machinery outside these categories.

Exigences techniques

The standard defines the critical geometric parameters for the driver's field of view, utilizing reference points such as V points (eye points) and P points (head rotation points) relative to the seating reference point (R point). It specifies the mandatory boundaries of the transparent area on the windshield based on specific angular degrees from the V points. A major focus is on obstruction limits. The standard dictates the maximum allowable binocular obstruction angle caused by A-pillars, setting strict limits to ensure adequate peripheral vision. It also outlines permissible obstructions from essential components like windshield wipers, specific radio antenna wires, and defrosting lines, provided they meet strict dimensional criteria. Significant updates include requirements for modern visibility technologies. The standard regulates the use of Camera-Monitor Systems (CMS) and Field of Vision Assistant (FVA) systems, detailing how their physical components and digital displays may obstruct the direct view. Manufacturers utilizing digital displays or camera-based mirror replacements must ensure these systems do not violate the established obstruction limits. Additionally, for vehicles with a higher seating position (where the V2 point height exceeds 1650mm), the standard introduces a specific forward blind spot evaluation. This requires that a cylindrical object of specified dimensions must be partially visible within a defined spatial zone in front of the vehicle, ensuring pedestrian safety for taller light-duty vehicles.

Méthodes d’essai

The standard outlines measurement procedures using a three-dimensional reference grid to establish the spatial relationship between the vehicle's primary reference marks and design points. Key evaluations include determining the windscreen datum points via ray tracing from V points, and measuring the A-pillar binocular obstruction angle using defined horizontal cross-sections (S1 and S2 sections) and E points (representing the driver's eyes). Measurements require the vehicle to be in a specific ready-to-drive mass state, with adjustable components like the steering wheel and FVA systems positioned according to manufacturer specifications.

Questions fréquentes

What types of vehicles are regulated under GB 11562-2025?

This standard applies specifically to M1 (passenger cars) and N1 (light commercial vehicles) category automobiles, regulating the direct forward visibility within a 180-degree range for drivers.

What are the main updates in GB 11562-2025 compared to the 2014 version?

The 2025 version introduces technical requirements for Camera-Monitor Systems (CMS) and Field of Vision Assistant (FVA) systems. It also adds visibility requirements for vehicles where the V2 point ground clearance exceeds 1650mm, and modifies regulations regarding steering wheel and dashboard obstructions.

When will the implementation of GB 11562-2025 take effect?

The standard includes specific implementation timelines. For newly type-approved vehicles, requirements for vision assistant systems apply starting the 13th month after implementation. For previously approved vehicles, these specific requirements apply starting the 25th month. Manufacturers must verify their production timelines against these phase-in dates.
