A first ECU and a plurality of second ECUs are connected to a communication bus. The first ECU repeatedly transmits a beacon signal through the communication bus. Each of the first ECU and the plurality of second ECUs transmits data according to an order set in advance when the beacon signal is transmitted. The first ECU or the second ECU transmits dummy data whose transmission destination is different from the remaining ECUs when there is no transmission data to be transmitted to one of the remaining ECUs other than itself.

Communication device, communication system, and communication method

A communicator (relay) receives a differential signal that is a voltage difference between two electrical signals that propagate through two respective conducting wires. The communicator removes noise from the two electrical signals using a first conductor as a reference potential. The communicator converts the differential signal that is the voltage difference between the two electrical signals with the noise removed into a voltage signal that is a voltage with the reference potential corresponding to a potential of a second conductor. The first conductor and the second conductor are respectively disposed on a first substrate and a second substrate. The first substrate and the second substrate are connected via a substrate connector with flexibility.
