Out-of-vehicle device interface apparatus and method for protecting in-vehicle network
First Claim
1. An out-of-vehicle device interface apparatus, comprising:
- a request message reception unit configured to receive a request message from an out-of-vehicle device, to generate electrical signals in electric lines, and to transfer the request message;
a response message request unit configured to request response messages for the request message from one or more devices constituting an in-vehicle network based on one or more of the electric lines in which electrical signals have been generated; and
a response message transmission unit configured to receive the response messages from the one or more devices, and to transfer the response messages to the out-of-vehicle device via unidirectional communication,wherein the response message request unit selects one or more request flags corresponding to one or more electric lines in which the electrical signals have been generated based on request flags set in the respective electric lines, and requests the response messages from the one or more devices based on the one or more request flags.

Abstract
An out-of-vehicle device interface apparatus includes a request message reception unit, a response message request unit, and a response message transmission unit. The request message reception unit receives a request message from an out-of-vehicle device, generates electrical signals in electric lines, and transfers the request message. The response message request unit requests response messages for the request message from one or more devices constituting an in-vehicle network based on one or more of the electric lines in which electrical signals have been generated. The response message transmission unit receives the response messages from the one or more devices, and transfers the response messages to the out-of-vehicle device via unidirectional communication.
