Document Type and Number:
Japanese Patent JP2017007401
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an on-vehicle relay device, an on-vehicle communication system, and a relay program that prevent an unauthorized message from being relayed between networks.SOLUTION: An on-vehicle relay device 10 having multiple communication units to which multiple CAN buses 2 and 3 are connected performs correctness determination of a message transmitted by ECU 20a-20f connected to the CAN buses 2 and 3. When a message is determined to be unauthorized, the on-vehicle relay device 10 notifies the CAN buses 2 and 3 connected to the communication unit having received the unauthorized message, of the transmission of the unauthorized message. The on-vehicle relay device 10 inhibits subsequent relay of messages having the same CAN-ID as the CAN-ID contained in the message determined to be unauthorized. At this point, the on-vehicle relay device 10 notifies a communication wire connected to communication units excluding the communication unit having received the message determined to be unauthorized, of the inhibited relay of the message.SELECTED DRAWING: Figure 1
