Abstract

The present invention relates to a system and method for controlling an integrated network of a vehicle, and more particularly, to a system and method, which separately identifies a malfunction of a plurality of communication networks applied to a vehicle and integrally controls power off and power on of the communication networks using a communication gateway. The integrated network system includes: a gateway configured to connect a plurality of networks; a plurality of vehicle networks connected to the gateway and connectable to each other by the gateway; and an Ethernet configured to transmit a signal processed in the gateway to the exterior of the gateway to analyze communication states of the plurality of vehicle networks connected to the gateway.

a plurality of vehicle networks connected to the gateway and connectable to each other by the gateway; and

an Ethernet configured to transmit a signal processed in the gateway to the exterior of the gateway to analyze a plurality of communication states of the plurality of vehicle networks connected to the gateway,

wherein the gateway classifies a plurality of received signals of the plurality of vehicle networks, and when a signal for powering on another network is detected among the classified signals, the gateway powers on the corresponding network.

2. The integrated network system of claim 1, wherein the plurality of vehicle networks comprises a controller area network (CAN), a local interconnect network (LIN), and a FlexRay.

3. The integrated network system of claim 2, wherein the gateway classifies a plurality of received signals of the plurality of vehicle networks, and when a signal for powering on another network is detected among the classified signals, the gateway powers on the corresponding network.

4. The integrated network system of claim 2, wherein the gateway is further configured to:

store a communication signal value generated in a corresponding network;

in response to determining a new communication signal generated in the corresponding network, compare the stored communication signal value with the new communication signal value to power off or power on the corresponding network to.

5. The integrated network system of claim 4, wherein the gateway is further configured to:

power off the corresponding network when the stored communication signal value is the same as the new communication signal value; and

power on the corresponding network when the stored communication signal value is different from the new communication signal value.

6. The integrated network system of claim 4, wherein the gateway is further configured to power off the corresponding network when a new communication signal is not generated in the corresponding network for a set time after the communication signal value generated in the network is stored.

7. The integrated network system of claim 2, wherein the gateway is further configured to:

determine a parking and stopping state of the vehicle using the signals input through the plurality of vehicle networks; and

power off the plurality of vehicle networks when the vehicle is in the parking and stopping state.

8. The integrated network system of claim 1, further comprising a communication analysis device configured to:

receive a signal processed in the gateway while accessing the Ethernet; and

analyze communication states of the plurality of networks based on the signal.

9. The integrated network system of claim 7, wherein the communication analysis device is further configured to set a login and a power off entry time in a network that is in a communication malfunction state among the plurality of networks.

10. The integrated network system of claim 1, wherein data transceived between the plurality of networks connected to the gateway includes a name of a corresponding electronic device, a power off mode or a power on mode command, and data indicating a state of the corresponding electronic device.

11. A method for controlling an integrated network system, the method comprising:

classifying, by a gateway, a plurality of received signals of a plurality of vehicle networks connected in the gateway;

detecting, by the gateway, a signal for powering on another network among the plurality of classified signals; and

powering on, by the gateway, a corresponding network through the detected signal, when a signal for powering on another network among the plurality of the classified signals exists.

12. The method of claim 11, further comprising:

storing, by the gateway, a communication signal value generated in the corresponding network;

determining, by the gateway, a new communication signal value generated in the corresponding network;

comparing, by the gateway, the stored communication signal value with the new communication signal value;

powering off, by the gateway, the corresponding network when the stored communication signal value is the same as the new communication signal value;

powering on, by the gateway, the corresponding network when the stored communication signal value is different from the new communication signal value; and

powering off, by the gateway, the corresponding network when the new communication signal value is not generated in the corresponding network for a set time after the communication signal value generated in the corresponding network is stored.

13. The method of claim 11, further comprising:

transmitting, by the gateway, a processed signal from the plurality of received signals to a communication analysis device via an Ethernet to analyze a plurality of communication states of the plurality of networks based on the processed signal.
