Gateway device, vehicle including the same, and control method for the same

A vehicle comprising:

• a plurality of vehicle modules configured to transmit/receive a CAN signal;
• and
• a gateway device connected to the plurality of vehicle modules and configured to transmit the CAN signal, which is received from any one of the plurality of vehicle modules, to at least one other of the plurality of vehicle modules, wherein
• the gateway device includes:
• a communication interface provided with a plurality of channels capable of connecting to the plurality of vehicle modules;
• a switch unit configured to determine a connection state between the plurality of channels;
• and
• a controller configured to group a CAN signal, which is received from a first vehicle module connected to a first channel among the plurality of vehicle modules, into a message frame, and when an identifier of the message frame is included in a pre-determined high-speed transmission identifier group, configured to control the switch unit so that a second channel, to which a second vehicle module corresponding to the identifier is connected, is connected to the first channel,
• the switch unit is further configured to connect the first channel to the second channel when the received CAN signal is grouped into a first message frame having an identifier included in the high-speed transmission identifier group, and
• the switch unit is further configured to directly transmit a CAN signal, which is based on a second message frame after the first message frame, to the second external device from the first channel.

A control method of a vehicle provided with a gateway device connected to a plurality of vehicle modules and configured to transmit a CAN signal, which is received from any one of the plurality of vehicle modules, to at least one of the plurality of vehicle modules, comprising:

• receiving a CAN signal from a first vehicle module connected to a first channel of the gateway device;
• grouping the received CAN signal into a message frame;
• connecting a second channel of the gateway device, to which a second vehicle module corresponding to the identifier is connected, to the first channel when an identifier of the message frame is included in a pre-determined high-speed transmission identifier group;
• and
• transmitting a CAN signal, which is based on a second message frame after the first message frame, to the second external device from the first channel by directly passing the second channel.
