Problems solved by technology

These units may not work properly in enclosed or heavily shaded areas
[0004] When the self-driving vehicle enters these closed or occluded areas, if the perception and positioning module fails to work normally, the self-driving vehicle will not be able to drive normally

Abstract

The embodiment of the invention provides a perceptual positioning switching method, device, server and system for an autonomous vehicle. The method comprises the steps of receiving notification information of a predetermined area, wherein the notification information comprises the information that a first perceptual positioning module exists in the predetermined area; according to the notificationinformation, sending an access request to the first perceptual positioning module of the predetermined area; receiving perceptual positioning information provided by the first perceptual positioningmodule, and according to the perceptual positioning information, determining control information for the autonomous vehicle. By means of the embodiment, when a perceptual positioning module of the autonomous vehicle cannot work normally, it still can be ensured that the autonomous vehicle normally drives.

Description

technical field [0001] The present invention relates to the technical field of automatic driving vehicles, in particular to a method, device, server and system for switching perception and positioning of automatic driving vehicles. Background technique [0002] The system of an autonomous vehicle usually includes a perception positioning module and a decision planning control module. Among them, the perceptual positioning module is used for environment perception and self-positioning. Environmental perception refers to the perception of the environment in which the autonomous vehicle is located, such as the location of obstacles, the detection of road signs / marks, the detection of pedestrians and vehicles, etc. Self-localization refers to determining the position of an autonomous vehicle relative to the environment. On the basis of determining the perception positioning information, the decision-making planning control module determines the control information for the self...
