Estimation of radiated immunity by individual evaluation of automotive communication modules

Abstract (in Japanese) (See Japanese page) 
(in English) Evaluating the immunity of in-vehicle communication is important, however measurement systems described in ISO 11452 do not separate the coupling characteristics of interference waves and wire harnesses from the immunity characteristics of in-vehicle equipment. Therefore immunity evaluation results do not always match test results in the vehicle environment.
In this report, we fabricated a communication module for 100Base-T1 and experimentally determined the applied power that causes malfunction of the communication module using it and a short wire harness. The radiated immunity was evaluated using a reverberation chamber method as the immunity performance of the communication module alone. The interference wave power injected by the reverberation chamber method is calculated by an electromagnetic field simulation, creating a simplified random electromagnetic field. A method for estimating malfunctions is proposed by determining whether the power applied by the radiated disturbance is the power that causes the malfunction. As a result, it was possible to determine the presence or absence of error in 30 out of the measured 42 frequencies.
