Abstract:
Provided is an on-board communication system that can prevent a communication line from being occupied due to repetitive transmission of an unauthorized message. The on-board communication system includes a plurality of interconnected ECUs and a monitoring device including: a determination processing unit to determine whether a message is an authorized message; a discard processing unit to perform processing for discarding an unauthorized message; a storage unit to store the ID of the discarded message; and a notification processing unit to perform processing for outputting, an ACK signal indicating that the reception of the message is complete. The discard processing unit does not discard a message with the same ID as that stored in the storage unit. Each of the ECUs stores the ID added to a message subjected to the discard processing, and prohibits processing of a message with the same ID as that stored in the storage unit.

Claim (Index 5):
An on-board communication system in which a plurality of communication device installed in a vehicle are connected to each other via a common communication line, comprising:\n a determination unit configured to determine whether or not a message transmitted on the communication line is an authorized message; a discard unit configured to perform processing for discarding any message determined by the determination unit not to be an authorized message, before the transmission of the message is complete; a counter configured to count the number of times when the message is discarded by the discard unit; and a reception completion notification unit configured to output to the communication line, if the number of times counted by the counter exceeds a predetermined number of times, a signal indicating that reception of the message is complete irrespective of a determination result of the determination unit, wherein the communication devices each include a prohibition unit configured to prohibit processing based on any received message if the number of times counted by the counter exceeds the predetermined number of times, and the discard unit does not discard the message if the number of times counted by the counter exceeds the predetermined number of times.
