  • Publication number: 20150085645
    Abstract: An Ethernet backbone network system for a vehicle and a method for controlling a fail safe of the Ethernet backbone network system enable high-speed and large-capacity data transmission between integrated control modules mounted in the vehicle, such that communication can be maintained through another alternative communication line when an error occurs in a specific communication line. The Ethernet backbone network system enables various kinds of integrated control modules mounted in the vehicle to perform large-capacity and high-speed communications, based on Ethernet communication, by connecting domain gateways of the integrated control modules through an Ethernet backbone network, and provides a fast fail-safe function so that domain gateways can perform communications through another communication line when an error occurs in a communication line between the domain gateways.

  • Publication number: 20150003456
    Abstract: An Ethernet based vehicle network message transferring system is provided that includes a gateway switch that connects the Ethernet to vehicle networks having different protocols and an Ethernet switch that switches Ethernet messages between the gateway switch and vehicle devices to transfer the Ethernet messages. The Ethernet switch includes a processing module that transfers the Ethernet messages received via the gateway switch in the different vehicle networks, a vehicle network process module that switches the messages transferred from the processing module, and a lookup table in which information necessary for switching the vehicle network process module is stored.

  • Publication number: 20140189621
    Abstract: An apparatus and a method for modeling a controller of a CAN bus are provided. The apparatus for modeling a controller of a CAN bus includes a modeling device for modeling a communication unit of a controller of the CAN bus and for evaluating the communication unit in a configuration of a CAN bus topology of the CAN bus. The modeling device includes an evaluation item determiner for determining the evaluation item used for simulating the configuration of the CAN bus topology, a factor determiner for determining factors that affect the evaluation result of the determined evaluation items, and a circuit design device for designing the circuit configured to include the determined factors.

  • Publication number: 20140165191
    Abstract: An apparatus for detecting an in-vehicle network attack, is configured to cumulatively count packets for each device that has a respective ID and is connected to an in-vehicle network bus. The apparatus is configured to cumulate a check value every time the packets are cumulatively counted to calculate a cumulated value, and determine that an attack is conducted when an average cumulated value obtained by dividing the cumulated value by a cumulative counted value does not exceed a first threshold value.

  • Patent number: 8711003
    Abstract: The disclosed system includes a first unit including at least one sensor. The first unit senses driving situations (characteristics) of a vehicle through the at least one sensor. Furthermore a second unit is configured to receive location-based information about the vehicle, and a control unit which includes an operation statistic unit calculates an acceptable range to be output by the first unit on a particular type of road based on the information detected by the sensing unit and the information received by the location second unit. The control unit also includes an abnormal driving determination unit which compares values sensed by the first unit with values calculated by the operation statistic unit to determine whether or not the vehicle is being driven in an abnormal state.
