Abstract

A method of positioning vehicles in an enclosed area, comprising the following steps: a. determining whether a reference object coordinate exists in the enclosed area, and if the reference object coordinate exists in the closed area, executing the step b; if no reference object coordinate exists in the closed area, executing the step c; b. calculating vehicle positioning information by an inertialnavigation sensor of a vehicle inertial navigation system; c. respectively calculating vehicle positioning information using a perception sensor and the inertial navigation sensor, wherein the perception sensor periodically corrects positioning errors of the inertial navigation system according to the reference object coordinate; and d, updating the positioning information of the vehicle.

Description

technical field [0001] The invention relates to a vehicle positioning method, in particular to a vehicle positioning method in a closed area. Background technique [0002] At present, the real-time location information of the vehicle cannot be obtained due to the shielding of the GPS signal by the vehicle in the closed space, making applications such as finding vehicles, vehicle navigation, and automatic / unmanned driving impossible. The existing technical solution is to use wireless signals to locate vehicles, such as adding multiple Wifi / LTE and other signal base stations to locate vehicles. However, due to many uncertain factors in closed areas, factors such as wireless signals or electromagnetic interference signal reflections will lead to measurement accuracy. It is not high or cannot receive signals, so it cannot meet the positioning requirements in closed venues. [0003] Therefore, there is an urgent need for a solution that can locate vehicles in a closed area. Co...
