Abstract: A signal processing device and a vehicle communication device including the same are disclosed. The signal processing device according to an embodiment of the present disclosure includes: a first processor configured to receive a first message including a sensor signal in a vehicle based on a first communication scheme; a second processor configured to receive a second message including a communication message received from an external source based on a second communication scheme; and a shared memory configured to operate to transmit the first message or the second message between the first processor and the second processor. Accordingly, it is possible to reduce latency and to perform high-speed data transmission during inter-processor communication.

Abstract: The present disclosure relates to an SDN-based in-vehicle network, and may provide a method for controlling an in-vehicle network, etc., the method comprising the steps of: on the basis of a priority of an Ethernet signal which is converted from a CAN signal so as to be transmitted from a first node to a second node, determining whether a bandwidth necessary for transmission of the Ethernet signal can be secured in a transmission path between the first node and the second node; if the bandwidth can be secured, controlling the Ethernet signal to be transmitted to the second node according to the transmission path; and if the bandwidth cannot be secured, changing the transmission path to pass through a third node, and controlling the Ethernet signal to be transmitted to the second node according to the changed transmission path.
