Claim 0:
1. A communication redundancy system for an autonomous vehicle, comprising:
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 controllers connected to the bus;
a plurality of gateways connected to the vehicle network domain; and
a high-level controller connected to the plurality of gateways and configured to control the plurality of controllers to implement autonomous driving of a vehicle,
wherein 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 controllers to the high-level controller, and
wherein each of the plurality of gateways is connected to a high line of the bus and a low line of the bus, and each of the plurality of gateways is connected between the terminal end resistor and a controller closest to the terminal end resistor.
