Abstract

At least one embodiment of the invention provides a communication link self-detection method, and relates to the technical field of automatic driving, the communication link is used for communicationbetween a publisher and a subscriber in a publish-subscribe communication framework, the method is executed by the subscriber, the subscriber is a virtual module defined in the publish-subscribe communication framework, and the method comprises the following steps: receiving first data information sent by the publisher; determining at least one communication state parameter of the first data information based on a first moment when the first data information is received and a second moment when the second data information before the first data information is received; and detecting whether thecommunication link is abnormal or not based on the at least one communication state parameter. At least one embodiment of the invention further provides a communication link self-detection system andan automatic driving vehicle.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of automatic driving, and in particular to a communication link self-inspection method and system performed by subscribers, and an automatic driving vehicle. Background technique [0002] The publish-subscribe communication framework is widely used in various electronic systems. Typically, self-driving vehicles also use this communication framework to communicate within the system to support end-to-end communication between different working modules in the self-driving vehicle system. The communication of the terminal; the operating status of the publish-subscribe communication framework plays a vital role in the stability and security of the entire autonomous vehicle system. Contents of the invention [0003] The present disclosure aims at at least solving the problem that the publish-subscribe communication framework in the prior art cannot detect whether there is an abnormality in...
