Intelligent car and positioning method used for intelligent transportation physical simulation platform

Abstract

The invention discloses an intelligent car and a positioning method used for an intelligent transportation physical simulation platform. Different from a radio frequency identification method in application to an electronic license plate, the positioning method includes the steps that a card reader is arranged inside the car when the intelligent car is positioned and navigated, passive electronic labels are laid on the road surface, and each passive electronic label corresponds to coordinates in a global coordinate system; when the intelligent car passes above the passive electronic labels, the card reader identifies UIDs of the passive electronic labels, and pose information corresponding to the UIDs is determined and used for correcting the position of a miniature inertia navigation system. The simulation platform can be used for experiment research and simulation display on intelligent vehicle coordination in a vehicle-vehicle and vehicle-road network environments, and uses an embedded system carried on the intelligent car for processing positioning information and then directly controlling the car, and therefore communication time is shortened.

Description

technical field [0001] The invention relates to an intelligent car and a positioning method for an intelligent traffic physical simulation platform, belonging to the field of traffic simulation methods. Background technique [0002] In order to alleviate the pressure of the increasing traffic congestion on the urban road network, the concept of intelligent transportation in the vehicle-vehicle-road network environment has received extensive attention. It is a combination of advanced communication network methods, sensor methods, computer methods and control methods. Traffic management methods that are organically combined, including vehicle-vehicle coordination, vehicle-road coordination, and other aspects. Since there are safety risks in directly applying new intelligent traffic methods to actual traffic, the intelligent traffic simulation platform based on road sand table and smart car is of great significance. The invention designs a method of simulating actual traffic r...

AI Technical Summary

Problems solved by technology

The GPS positioning method has a good effect in the outdoor environment, but it cannot be applied to the indoor environment due to the decrease in accuracy due to occlusion and other reasons. As an indoor positioning method, the wireless sensor network positioning method has attracted more and more attention from developers. The sensor network positioning method is still unable to achieve accurate indoor positioning

At present, the only method that can achieve accurate indoor positioning is the video positioning method. Since the road sand table is a double-layer structure, the video positioning method cannot solve the problem of occlusion between the upper and lower roads, and cannot be applied to this platform.
