The present disclosure provides methods for releasing a reserved resource in a network. An operation method performed in a first communication node of a vehicle network includes generating a first frame including identification information of a stream transmitted through a reserved resource and a first indicator instructing to release the reserved resource; and transmitting the first frame to a second communication node.

Method of releasing resource reservation in network

Operation methods of a first communication node in a network, in particular, an Ethernet-based vehicle network, include: transmitting, by the first communication node to at least one communication node which is connected to the first communication node, a first frame requesting state information of a physical layer between the first communication node and the at least one communication node; receiving, by the first communication node from the at least one communication node, a second frame in response to the first frame; and identifying, by the first communication node, a state of the physical layer based on the second frame when the second frame is received.

Operation methods of communication node in network

A time synchronization method performed by a communication node in a vehicle includes: receiving, from a road side unit (RSU), a first frame including time information of a first domain to which the RSU belongs; setting a time of the vehicle based on a time indicated by the time information of the first domain; and transmitting a second frame including the time information of the vehicle.

Method for time synchronization of domain based on time information of vehicle

A method for configuring a communication path comprises: receiving a first frame requesting to configure a communication path through which a stream is transmitted; configuring a table of the first communication node based on information included in the first frame, when a second frame having a same stream identifier as a stream identifier of the first frame is not received; increasing a hop count of the first frame; and transmitting the first frame including the increased hop count.

Method for configuring stream communication path in network

An operation method of a switch apparatus in an Ethernet-based vehicle network, includes: receiving a first frame including original data from an end node; generating a second frame including the original data; duplicating the original data to generate duplicated data; and generating a third frame including the duplicated data and an indicator indicating that the third frame includes the duplicated data.

Method of transmitting data based on priorities in network

An operation method of a communication node in an Ethernet-based vehicle network includes: transmitting a first frame advertising a presence of a data unit to be transmitted; receiving a second frame indicating that preparation for receiving the data unit is completed; and transmitting a third frame including the data unit using a static bandwidth which is reserved through an exchange of the first frame and the second frame.

Operation method of communication node in network

Disclosed are time synchronization methods for domains based on time information of a vehicle. A time synchronization method performed by a first end node belonging to a first domain of a vehicle includes: receiving a first frame including time information from the vehicle; changing the first end node to a grand master node of the first domain when the time information indicates a time of a universal time domain; and synchronizing a time of the grand master node with the time of the universal time domain.

An operation method of a first communication node among a plurality of communication nodes constituting an Ethernet-based vehicle network may comprise receiving a message from a second communication node; determining whether a source address of the message exists in a first address table stored in a memory of the first communication node; and transmitting the message and information on the source address of the message to a management node in response to determining that the source address of the message exists in the first address table.

System for verification of unregistered device based on information of Ethernet switch and method for the same

An operation method of a first communication node includes: measuring a magnitude of a current supplied to a second communication node through a data line in the vehicle network; comparing the measured magnitude of the current with a predetermined threshold value; generating an address resolution protocol (ARP) frame including fault-related information when the second communication node is determined to be in a fault state based on a result of the comparison; and transmitting the ARP frame.

Power management method in network and apparatus for the same

An apparatus and method are provided for controlling a high voltage battery within vehicle. The apparatus monitors states of a first temperature sensor and a second temperature sensor mounted within a battery pack and calculates a replacement temperature that corresponds to the faulty temperature sensor using a temperature deviation within the battery pack for each ambient temperature of the battery when a faulty temperature sensor of the first temperature sensor and the second temperature sensor is detected. The replacement temperature is then used to operate the battery, and thus the stability of the battery control is improved even though the temperature sensor of the battery fails.

Apparatus and method for controlling a high voltage battery in vehicle

A method and apparatus for analyzing a signal delay time based on controller area network (CAN) burst are disclosed. An apparatus for analyzing a signal delay time, connected to a controller area network (CAN) bus includes a measuring device configured to determine a transmission start time based on a receiving time point of a CAN signal and to determine a receiving time interval between the CAN signals that are continuously received, a fixer configured to fix a burst period corresponding to CAN signals with the determined receiving time interval less than a predetermined value, a selector configured to select an analysis target CAN signal in the fixed burst period, and a determiner configured to determine a maximum transmission delay time 'a' corresponding to the selected CAN signal.

Method and apparatus for analyzing signal delay time based on controller area network burst analysis

An apparatus for a compliance test on a communication node includes: a monitoring port; a switch turning on or off a connection between the monitoring port and a communication port connected to the communication node; and a processor controlling the switch to turn on or off the connection between the monitoring port and the communication port.
