VEHICLE-MOUNTED COMMUNICATION SYSTEM, DETERMINATION DEVICE, COMMUNICATION DEVICE, DETERMINATION METHOD, AND COMPUTER PROGRAM

WIPO Patent Application WO/2019/225369

A1

Provided is a vehicle-mounted communication system in which a plurality of communication devices and a determination device for determining the presence or absence of abnormality related to the communication devices are connected via a bus, wherein the determination device is provided with a transmission unit which transmits a determination signal having a predetermined voltage to each of the communication devices, and a determination unit which determines the presence or absence of the abnormality on the basis of a response signal transmitted from each of the communication devices in response to the determination signal, each of the communication devices is provided with a signal output unit which, in response to the received determination signal, outputs a first logical value signal on the basis of a unique voltage threshold, and a generation unit which generates a second logical value signal on the basis of the first logical value signal, and the signal output unit outputs the response signal to the bus on the basis of the second logical value signal.
