Abstract
A vehicle-mounted communication system in which a plurality of communication devices and a determination device for determining an abnormality regarding the communication devices are connected to each other via a bus, wherein the determination device includes: a transmitting unit that transmits a determination signal at a predetermined voltage to each of the communication devices; and a determination unit that determines the abnormality based on a response signal transmitted from each of the communication devices in response to the determination signal, each of the communication devices includes: a signal output unit that outputs a first logical value signal based on a unique voltage threshold, in response to a determination signal that is received; and a generating unit that generates a second logical value signal based on the first logical value signal, and the signal output unit outputs the response signal to the bus based on the second logical value signal.
