Champ d’application

This standard specifies the performance requirements and test methods for Tire Pressure Monitoring Systems (TPMS) installed on M1 category vehicles (passenger cars). It is a mandatory national standard replacing the previous GB/T 26149-2010. The standard applies to all new and existing passenger car models seeking type approval in China, with specific implementation timelines based on vehicle configurations.

Exigences techniques

The standard classifies TPMS into two categories: Type I and Type II, each with distinct functional and performance criteria regarding warning signals and response times. It mandates that systems must comply with ECE R10 for electromagnetic compatibility. Manufacturers must ensure their TPMS provides clear optical warnings for both under-inflation and system faults. Core requirements focus on signal device specifications, including the mandatory use of specific warning symbols, yellow illumination color, and placement in an easily observable position. The standard defines strict parameters for single-tire and multiple-tire under-inflation warnings, requiring the system to detect pressure drops and alert the driver within specified timeframes. Additionally, the standard outlines requirements for fault alarms, ensuring the system alerts the driver when a TPMS component fails. Vehicle manufacturers must adhere to these safety-related core functions to achieve compliance.

Méthodes d’essai

The standard details rigorous testing procedures, including the Signal Device Check Test to verify warning lamp functionality upon ignition. It also specifies the Single-Tire Under-Inflation Test and Multiple-Tire Under-Inflation Test, which evaluate the system's response time and positional indication accuracy under various driving speeds (e.g., stationary, 40 km/h, 100 km/h). Finally, a Fault Alarm Test is conducted by simulating system failures (such as disconnecting power or installing incompatible tires) to ensure proper fault detection.

Questions fréquentes

What products are regulated under GB 26149-2017?

GB 26149-2017 regulates Tire Pressure Monitoring Systems (TPMS) specifically designed for M1 category vehicles (passenger cars) in the Chinese market.

Is GB 26149-2017 a mandatory standard?

Yes, GB 26149-2017 is a mandatory national standard. Chapters 4 through 8 contain compulsory requirements, replacing the previously recommended GB/T 26149-2010.

When did the implementation of GB 26149-2017 begin?

For most M1 vehicles, implementation began on January 1, 2019, for new type approvals and January 1, 2020, for existing approved models. Mid-engine passenger cars with a width-to-height ratio ≤ 0.9 had later deadlines in 2020 and 2021.
