COMMUNICATION REDUNDANCY SYSTEM FOR AN AUTONOMOUS VEHICLE

A communication redundancy system for an autonomous vehicle includes: a vehicle network domain including a bus configured to transmit a signal, terminal end resistors disposed at both ends of the bus, and a plurality of electronic control units (ECUs) connected to the bus; a plurality of gateways connected to the vehicle network domain; and a high-level ECU connected to the plurality of gateways and configured to control the plurality of ECUs to implement autonomous driving of a vehicle. Each of the plurality of gateways detects disconnection of the bus in the vehicle network domain and, when the disconnection of the bus is detected, the plurality of gateways transmit pieces of data of the plurality of ECUs to the high-level ECU.
