AI Technical Summary

Technical Problem

In the existing technology, vehicle electromagnetic radiation testing is carried out under steady-state power supply voltage, which makes it difficult to test the electromagnetic radiation characteristics of the vehicle under real transient undervoltage conditions, resulting in low test accuracy.

Method used

In the vehicle's testing environment, electromagnetic radiation data and power waveform data under the influence of disturbance noise applied by the disturbance generator are collected. Time correlation data are obtained through correlation analysis, and electromagnetic tests are conducted on the vehicle based on this data to determine the electromagnetic radiation status under steady-state and transient conditions.

Benefits of technology

It enables accurate testing of vehicle electromagnetic radiation status under real transient undervoltage conditions, thus improving the accuracy of electromagnetic radiation testing.
