Abstract: An in-vehicle message transmission method includes receiving a network management (NM) message from a Controller Area Network (CAN) network, transmitting a wakeup pulse to an Ethernet network in response to the NM message, storing an Ethernet message into which a CAN message received from the CAN network is converted in a gateway, and transmitting the Ethernet message to an Ethernet node when a Transmission Control Protocol (TCP) connection with the Ethernet node to receive the Ethernet message is established.

Abstract: A reprogramming apparatus for vehicle, a reprogramming method and a vehicle including the same are provided.

Abstract: A vehicle system includes: a first vehicle network management control apparatus that manages a first network; and a second vehicle network management control apparatus that communicates with the first vehicle network management control apparatus and manages a second network. The first and second vehicle network management control apparatuses enter a sleep mode while synchronizing with each other.

Abstract: A software defined network (SDN)-based network management apparatus includes: an SDN controller including a first management unit to store a plurality of heterogeneous protocol information items, and an SDN switch controlled by the SDN controller and including a second management unit to store at least one heterogeneous protocol information item acquired from the SDN controller and a gateway to communicate with a vehicle network. In particular, upon receiving a packet corresponding to a new protocol that has not been used for access, from an external source, the SDN switch sends a request to the SDN controller for analysis of the received packet, and the SDN controller forwards protocol information corresponding to the received packet among the plurality of heterogeneous information items stored in the first management unit, to the SDN switch.

Abstract: A vehicle to vehicle (V2V) communication method and an apparatus using the same, for changing a communication method with a surrounding vehicle in consideration of an event type, may include: when an event occurs, determining whether the event is an important event, when the event is the important event, broadcasting data of the event, when the event is not the important event, determining a transmission method depending a communication situation with a surrounding vehicle, and multicasting or broadcasting the data of the event depending on the determined transmission method.

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.
