A first ECU (11) acquires external information from an external device, and performs information communication based on a communication message stipulated in a CAN protocol via a communication bus (10). The first ECU (11) is provided with: a communication necessity/unnecessity determination unit (113) which determines the necessity or unnecessity of the information communication via the communication bus (10) on the basis of the acquired external information; and a communication control unit (114) which, when the information communication is determined to be necessary, stops the information communication for a given period on condition that a communication error is detected, and resumes the information communication after a lapse of the given period, and when the information communication is determined to be unnecessary, stops the transmission of the communication message until a predetermined transmission resumption condition is satisfied.
