GB T 38975 EMC Test for Intelligent Connected Vehicles
The GB T 38975 standard is a crucial cornerstone in ensuring that intelligent connected vehicles (ICVs) meet the stringent electromagnetic compatibility (EMC) requirements set by China. This standard encompasses a comprehensive suite of tests designed to verify whether ICVs can operate correctly and without interference when interacting with other electronic devices within their environment.
The primary objective is to safeguard both the vehicle's performance and the safety of its occupants, passengers, pedestrians, and other road users. By adhering to this standard, manufacturers ensure that vehicles are robust against electromagnetic disturbances, thereby enhancing overall system reliability and preventing potential failures in critical functions such as braking systems, steering mechanisms, or communication networks.
Testing under GB T 38975 involves several key procedures aimed at simulating real-world scenarios where the vehicle might encounter various types of electromagnetic interference (EMI). These tests are divided into two main categories: conducted emissions and radiated emissions. Conducted emissions measure the electrical signals transmitted through wires or cables, while radiated emissions assess the radio frequency (RF) energy emitted by electronic devices.
For instance, during a conducted emissions test, engineers connect the vehicle to a spectrum analyzer equipped with appropriate filters and connectors. They then apply specific frequencies across different bands that are relevant to ICVs, such as those used for mobile communications or GPS satellite signals. Similarly, in radiated emissions testing, an anechoic chamber is utilized to isolate the vehicle from external interference sources, allowing precise measurement of any electromagnetic waves it emits.
Compliance with GB T 38975 necessitates rigorous preparation steps before conducting these tests. This includes thorough cleaning of all electronic components within the vehicle, ensuring they are free from dust and dirt that could affect test results. Additionally, detailed documentation must accompany each specimen undergoing testing, providing comprehensive information about its configuration, software version, and hardware specifications.
Upon completion of the testing process, detailed reports are generated summarizing all findings. These documents typically include graphs depicting measured values against predefined limits specified in GB T 38975, along with interpretations explaining any deviations from acceptable ranges observed during the tests. Such insights help identify areas requiring further improvement or optimization within a vehicle's design.
- Conducted Emissions: Focuses on measuring electrical signals transmitted through wires and cables used in ICVs.
- Radiated Emissions: Assesses the radio frequency energy emitted by electronic devices within ICVs.
- Anechoic Chamber: Used to isolate vehicles from external interference sources during radiated emissions testing.
