Abstract

The invention relates to the technical field of testing, and provides a calibration device for testing the immunity of automobile electronic conduction. A calibration device for automotive electronic conduction immunity testing, including a signal generator, an amplification module, an inductive coupling clamp, a matching module, a measurement module, a transmission module and a tooling fixture, the tooling fixture is used to fix and support the transmission module and is The jig connecting the transmission module and the matching module, the interference signal generation module injects interference current through the inductive coupling clamp, and verifies the induced current generated on the transmission line through magnetic induction coupling. The verification device used for the test of the immunity of automobile electronic conduction can ensure the reliability and stability of the test, has high operability, strong repeatability, is economical, simple and easy to operate, has a simple and stable structure, and saves time and cost. The advantages. The invention also proposes a calibration method for testing the immunity of automobile electronic conduction.

Description

technical field [0001] The invention relates to the technical field of testing, more specifically, to a calibration device and a calibration method for automotive electronic conduction immunity testing. Background technique [0002] The various wiring harnesses connected to the car become a passive receiving antenna network during the operation of the electronic equipment, and it is very easy to generate induced voltage or current under the action of the external electromagnetic field. A large part of the electromagnetic field in the space is magnetically coupled through the bundled cable harness. , causing interference to on-board electronic components / modules. The purpose of the conduction immunity test is to verify whether the automotive electronic components / modules can work normally to achieve their expected performance state or perform their expected design functions when they are interfered by the radio frequency electromagnetic energy coupled by the cable harness, an...
