Title:

IN-VEHICLE COMMUNICATION SYSTEM AND METHOD, AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/228396

Kind Code:

A1

Abstract:

An in-vehicle communication system applied to a vehicle, comprising a control device, a plurality of gateway devices, and communication endpoints. Each gateway device is communicationally connected to the control device, each gateway device is communicationally connected to at least two other gateway devices; and each gateway device is also communicationally connected to at least one communication endpoint. A particular gateway device or the control device is configured to, upon receiving communication data for end-to-end communication, route the communication data by means of a first communication link indicated by a local routing policy, and to route part of or all of the communication data by means of a second communication link if the first communication link is abnormal. The present system can be applied to the field of assisted driving and autonomous driving, as well as other similar application scenarios in the field of communications that do not relate to the Internet of vehicles. The implementation of the in-vehicle communication connection redundancy of intelligent vehicles facilitates the implementation of low-latency, robust, stable and reliable in-vehicle communication, and improves the safety of autonomous vehicles.
