Abstract
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.
Claims16
An operation method of a first communication node in a vehicle network, the method comprising:
- 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.
A first communication node in a vehicle network, the first communication node comprising:
- at least one switch controlling a power supply;
- a processor controlling the at least one switch;
- and
- a memory storing at least one instruction code executed by the processor,
- wherein, when the at least one stored instruction code is executed, the processor is caused to:
- measure a magnitude of a current supplied to a second communication node through a data line in the vehicle network;
- compare the measured magnitude of the current with a predetermined threshold value;
- generate 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
- transmit the ARP frame.
