Apparatus and method of monitoring ethernet communication for vehicle and vehicle including the same

An Ethernet communication monitoring method of an Ethernet communication monitoring apparatus for a vehicle including a monitoring unit configured to monitor a communication state of an Ethernet switch connected to a plurality of controllers, the method comprising:

• calculating a reference value of normal traffic statistics data for each port, between ports, and for each traffic flow of the Ethernet switch based on communication information between the controllers and a switching path of the Ethernet switch, by the monitoring unit;
• monitoring whether an abnormal traffic port in which abnormal traffic statistics data is generated is present among ports of the Ethernet switch based on the calculated reference value of the normal traffic statistics data for each port, by the monitoring unit;
• monitoring whether abnormal traffic statistics data are present between the abnormal traffic port and a port that transmits a message to the abnormal traffic port based on the calculated reference value of the normal traffic statistics data between ports when the abnormal traffic port is present, by the monitoring unit;
• monitoring whether abnormal traffic flow is present between the abnormal traffic port and the port that transmits the message to the abnormal traffic port based on the calculated reference value of the normal traffic statistics data for each traffic flow when the abnormal traffic is present, by the monitoring unit;
• and
• providing information on the abnormal traffic flow to signal communication abnormality of the Ethernet switch when the abnormal traffic flow is present, by the monitoring unit.

A vehicle comprising:

• an Ethernet switch communication-connected to a plurality of controllers;
• and
• an Ethernet communication monitoring apparatus configured to monitor whether a communication state of the Ethernet switch is abnormal,
• wherein the Ethernet communication monitoring apparatus calculates a reference value of normal traffic statistics data for each port, between ports, and for each traffic flow of the Ethernet switch based on communication information between the controllers and a switching path, compares the calculated reference value of the normal traffic statistics data with traffic statistics data acquired from each of ports of the Ethernet switch, and monitors whether a communication state of the Ethernet switch is abnormal.
