A frame conversion apparatus for converting a CAN frame into an Ethernet frame and a frame conversion method thereof, configured to efficiently convert CAN frame data into Ethernet frame data, to achieve high-speed and high-volume transmission.

Frame conversion apparatus for converting controller area network frame into ethernet frame and frame conversion method thereof

The present invention provides a method and apparatus for setting up a gateway for an AUTOSAR-based vehicle network. The apparatus for setting up the gateway includes a candidate selection unit for selecting an Electronic Control Unit (ECU) connected to at least two communication clusters, from among a plurality of ECUs, as a gateway candidate, and a gateway generation unit for generating a gateway instance with reference to the ECU selected by the candidate selection unit, and generating a gateway meta-model including the gateway instance based on instance generation input values entered by a user.

Method and apparatus for setting up gateway for AUTOSAR-based vehicle network

The present invention relates to a automotive partial networking apparatus and method, which operate or terminate only a specific electronic control unit corresponding to a service currently being provided in a vehicle network composed of a plurality of electronic control units. In the automotive partial networking method, a automotive partial networking apparatus receives a partial networking-only Controller Area Network (CAN) frame from outside of the apparatus. A partial network table is searched based on the CAN frame, and then a CAN identification (ID) is searched for. A partial networking-only CAN frame is generated using the CAN ID. Partial networking is performed by transferring the generated partial networking-only CAN frame to at least one electronic control unit corresponding to a vehicle service.

Automotive partial networking apparatus and method

Disclosed herein are an apparatus and method for collecting vehicle diagnostic information. The apparatus for collecting vehicle diagnostic information includes a conversion unit and an optical multiplexing unit. The conversion unit receives a plurality of frames complying with respective different protocols from a plurality of networks for vehicles, which collects vehicle diagnostic information, in electric signal form, and converts the plurality of frames into a plurality of optical signals having respective different wavelengths based on the wavelengths previously assigned to the respective protocols. The optical multiplexing unit generates a wavelength division multiplexed signal by performing wavelength division multiplexing (WDM) on the plurality of optical signals, and transmits the wavelength division multiplexed signal via an optical cable.

Apparatus and method for collecting vehicle diagnostic information

A data traffic processing method in a subscriber network access subsystem of an advanced communications processing system is disclosed including an operation process of a data processing master module and an operation process of a data processing slave module. The operation process of the data processing master module includes the steps of: initializing hardware, displaying a system logo on a screen and initializing all parameters; initializing the data processing master module; and initializing a slave and informing a service processing board assembly (SPA) that a master execution preparation has been ended. The operation process of the data processing slave module includes the steps of: initializing the hardware and displaying the system logo on the screen; initializing the data processing slave module; and informing a master that the slave is an alive state and initializing a protocol parameter.
