Abstract

An in-vehicle communication system includes a gateway that relays communication between an external apparatus and an in-vehicle LAN; and a communication permission determination unit that inhibits communication between the external apparatus and the in-vehicle LAN through the gateway if it is determined that a vehicle having the in-vehicle LAN mounted therein is in a parking state based on acquired predetermined vehicle information.

Claims (11)

1 . An in-vehicle communication system comprising:

a gateway that is configured to relay communication between an external apparatus and an in-vehicle LAN; and

a communication permission determination unit that is configured to inhibit communication between the external apparatus and the in-vehicle LAN through the gateway if it is determined that a vehicle having the in-vehicle LAN mounted therein is in a parking state based on acquired predetermined vehicle information.

2 . The in-vehicle communication system according to claim 1 , wherein:

the communication permission determination unit determines whether an abnormality is detected in an acquisition source of the predetermined vehicle information; and

if it is determined that an abnormality is detected in the acquisition source, the communication permission determination unit permits communication between the external apparatus and the in-vehicle LAN through the gateway.

3 . The in-vehicle communication system according to claim 2 , wherein the communication permission determination unit determines the abnormality is detected in the acquisition source when a time during which the vehicle information is not received in a communication in which the gateway acquires the vehicle information exceeds a predetermined time.

4 . The in-vehicle communication system according to claim 1 , wherein:

the communication permission determination unit determines an importance level of information stored in apparatuses included in the in-vehicle LAN; and

the communication permission determination unit permits communication between an internal apparatus and the external apparatus, the internal apparatus being one of the internal apparatuses included in the in-vehicle LAN, the internal apparatus not including information the importance level of which is determined high.

5 . The in-vehicle communication system according to claim 1 , wherein the communication permission determination unit determines that the vehicle is in the parking state if at least one of conditions is satisfied, the conditions including a condition in which the vehicle is in a security caution state, a condition in which the vehicle is in a security warning state, a condition in which all doors of the vehicle are closed and locked through a wireless key operation or a smart key operation, and a condition in which a smart key is not present in a passenger space of the vehicle.
