Abstract
A vehicle-mounted relay device includes a hardware unit implementing functions of first to third layer of OSI model, and a software unit implementing functions of fourth and upper layers of OSI model. The hardware unit includes a first abnormality recording section in which an abnormal frame detected during data relay is recorded, and a first abnormality recording processing section storing, in response to detection of the abnormal frame, the abnormal frame in the first abnormality recording section. The software unit includes a second vehicle information recording section in which vehicle information sequentially transmitted from an end ECU is stored, and a first diagnostic recording processing section, which reads out the abnormal frame from the first abnormality recording section and reads out the vehicle information from the second vehicle information recording section, and stores the readout abnormal frame and vehicle information in a diagnostic information recording section as diagnostic information.
