Document Type and Number:
WIPO Patent Application WO/2022/230447
Kind Code:
A1
Abstract:
In the present invention, a first ECU (11) and a plurality of second ECUs (12) are connected to a communication bus (B). The first ECU (11) repeatedly transmits a beacon signal via the communication bus (B). When the beacon signal is transmitted, each of the first ECU (11) and the plurality of second ECUs (12) transmits data in accordance with a predetermined sequence. When there is no transmission data to be transmitted to one of the remaining ECUs other than a host unit, the first ECU (11) or the second ECUs (12) transmit dummy data for which the transmission destination is different than the remaining ECUs.
