Abstract

A system for accessing to vehicle network includes a gateway extracting requested information from an in-vehicle network to transfer to an external device when an information request of the external device is a pre-registered inspect request and outputting a selection signal for a sector which an authenticated external device requested after performing an authentication for the external device when the information request is not the pre-registered inspect request. The system further includes a signal transmitter connecting the external device with the in-vehicle network corresponding to the sector that the external device requests when the selection signal is received from the gateway.

Claims

1. A system for accessing a vehicle network, the system comprising:

a gateway extracting requested information from an in-vehicle network to transfer to an external device when an information request of the external device is a pre-registered inspect request and outputting a selection signal for a sector which an authenticated external device requested after performing an authentication for the external device when the information request is not the pre-registered inspect request; and

a signal transmitter connecting the external device with the in-vehicle network corresponding to the sector that the external device requests when the selection signal is received from the gateway.

2. The system of claim 1, further comprising:

an external transceiver providing a connecting path for transmitting and receiving data between the external device and the gateway or the signal transmitter; and

an internal transceiver providing a connecting path for transmitting and receiving data between the in-vehicle network and the gateway or the signal transmitter.

3. The system of claim 2, wherein the gateway transmits a first authentication key to the corresponding external device when a monitoring request is received from the external device and performs a verification process by receiving a second authentication key converted from the first authentication key from the external device to perform an authentication for the external device.

4. The system of claim 2, wherein the signal transmitter enables the external device to directly connect to a data bus of the in-vehicle network.

5. A method of controlling an accessing system for a vehicle network, the method comprising:

determining whether a received information request is a pre-registered inspect request when the information request is received from an external device;

extracting requested information from an in-vehicle network to transfer to the external device when the information request is the pre-registered inspect request, and performing an authentication procedure for the external device when the information request is not the pre-registered inspect request; and

connecting the external device to the in-vehicle network corresponding to a sector that the external device requested when the external device is an authenticated external device.

6. The method of claim 5, wherein the authentication procedure for the external device comprises:

transmitting a first authentication key to the corresponding external device when a monitoring request is received from the external device;

receiving a second authentication key converted from the first authentication key from the external device; and

verifying the second authentication key.

7. The method of claim 5, wherein connecting the external device to the in-vehicle network comprises directly connecting the external device to a data bus.
