1. An in-vehicle communications system, comprising:
at least one control device;
a plurality of gateway devices; and
a plurality of communication endpoints, wherein each gateway device is communicatively coupled to the control device and at least two other gateway devices of the plurality of gateway devices, and each gateway device is further communicatively coupled to at least one communication endpoint, wherein the at least one control device is configured to transmit first communication data, and the plurality of gateway devices include a first gateway device, and wherein the at least one control device has one or more functions of intelligent driving, an intelligent cockpit, or vehicle control by controlling each of the communication endpoints by receiving and processing data from the communication endpoint;
wherein the first gateway device is configured to: when receiving the first communication data, transmit the first communication data by using a first communication link indicated by a routing policy, and when the first communication link is abnormal, transmit a part or all of the first communication data by using a second communication link indicated by the routing policy, and
wherein the first communication data includes at least one of the following: communication data between at least two communication endpoints of a plurality of communication endpoints coupled to the plurality of gateway devices, communication data between at least two gateway devices of the plurality of gateway devices, communication data between any communication endpoint of the plurality of communication endpoints and the control device, or communication data between any gateway device of the plurality of gateway devices and the control device.
