| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, Ethernet communications have been attracting attention as high-speed and large-capacity communication methods with an increase in the amount of information handled in in-vehicle networks. Immunity tests are required to ensure the reliability and safety of in-vehicle communication devices. Although pulse disturbances used for in-vehicle Ethernet immunity tests have been specified, the characteristics of disturbances that cause communication quality degradation and the cause of malfunction that occur when disturbances are applied have not been elucidated. To improve the immunity test reliability and shorten the test time, it is necessary to elucidate the relation between communication quality and parameters of disturbances and the mechanism of malfunction caused by pulse disturbances. In this report, as an early study, we focus on the consumer Ethernet communication standards 100BASE-TX and 1000BASE-T. To investigate the relation between the pulse parameters and communication quality and the mechanism, we conducted an experiment to apply pulse disturbances in differential mode to the differential communication lines. As a result, we found the differences in the parameters of the pulse disturbances to cause degradation of communication quality. Also, the data errors were observed that were inferred to result from different mechanisms in each standard. | |
