Title:
VEHICLE-MOUNTED COMMUNICATION SYSTEM AND MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/065100
Kind Code:
A1
Abstract:
Provided are a vehicle-mounted communication system and a monitoring device with which it is possible to prevent unauthorized messages being repeatedly transmitted and occupying a communication line. In this monitoring device: IDs of messages to be monitored are stored as monitored IDs in a storage unit; a determination processing unit determines whether or not a message transmitted on a communication line is a legitimate message; and a discarding processing unit causes messages determined not to be legitimate messages to be discarded prior to completion of message transmission. When the process to cause an unauthorized message to be discarded has been performed by the discarding processing unit, the monitoring device uses a change processing unit to perform a process to change the corresponding ID of the message to be monitored. Similarly, when the discarding process has been performed by the monitoring device, each ECU uses a change processing unit, with which each ECU is provided, to change the ID to be appended to messages sent and received by the ECU. Each ECU prohibits processing from being performed on the basis of messages to which the unchanged ID has been appended.
