Base station, tag, server, system and method for automatic driving for parking lot

Abstract

The invention provides an automatic driving method for a parking lot. The automatic driving method for a parking lot includes the steps: an establishing step: setting a positioning base station group covering a parking area, wherein the positioning base station group includes a plurality of positioning base stations which are distributed in the parking area at intervals; a determination step: determining the latitude and longitude coordinates of at least one positioning base station in the positioning base station group; and a driving step: according to the latitude and longitude coordinates of at least one positioning base station, determining the latitude and longitude coordinates, of an automatic driving vehicle, interacting with the positioning base station group so as to enable the automatic driving vehicle to perform automatic driving according to the latitude and longitude coordinates of the automatic driving vehicle. As the automatic driving method for a parking lot can perform positioning through the positioning base stations when GPS or Beidou signals cannot be received at an underground parking lot, safety and accuracy of the automatic driving vehicle can be guaranteed. Moreover, the automatic driving method for a parking lot can determine the latitude and longitude coordinates of the automatic driving vehicle by means of the positioning base stations, so that the automatic driving method for a parking lot can be directly used without modifying the middle control system of the automatic driving vehicle and modifying the vehicle, and then the automatic driving method for a parking lot is convenient for popularization.

Description

technical field [0001] The present application relates to the field of automatic driving, in particular to a parking lot automatic driving base station, tag, server, system and method. Background technique [0002] Nowadays, most of the self-driving vehicles researched or put into operation by various manufacturers use GPS for positioning and driving guidance. Since satellite positioning equipment such as GPS or Beidou needs to be used in an open outdoor environment with satellite communication conditions, the signal is easily blocked by buildings. Especially in underground parking lots, it is almost difficult to achieve satellite positioning. [0003] At the same time, the central control system of the self-driving vehicle now converts the GPS signal or the Beidou signal into the latitude and longitude coordinates, and then drives according to the latitude and longitude coordinates. If other positioning methods are used in areas that cannot be covered by satellites, a larg...

Problems solved by technology

If other positioning methods are used in areas that cannot be covered by satellites, a large number of modifications to the central control system of the self-driving vehicle will be required, which is not compatible with the existing system
