Abstract
A vehicle communication system includes a plurality of ECUs connected by the communication network including a plurality of communication transmission lines. Each of the ECUs includes an identification unit that identifies a target ECU to be a communication partner, and a relay transmission line and a relay ECU through which communication with the target ECU is routed, a standby time determination unit that determines a transmission standby time based on information on the relay ECU, the transmission standby time being a time from transmission of an activation instruction to another one of the ECUs closest to the ECU along the relay transmission line to transmission of a control signal toward the target ECU, and a communication unit that transmits the control signal after an elapse of the transmission standby time after transmitting the activation instruction to the relay transmission line closest to the ECU.
