Road vehicle automatic driving control system based on ultra-wideband positioning system

Abstract

The invention discloses a road vehicle automatic driving control system based on an ultra-wideband positioning system, which comprises a vehicle-mounted assembly and more than two ultra-wideband positioning base stations, wherein the vehicle-mounted assembly is arranged on a vehicle, the vehicle-mounted assembly comprises an automatic driving controller, an electrically-controlled steering device, an ultra-wideband label and a vehicle ground communication device, the ultra-wideband label is a positioning label for transmitting an ultra-wide frequency signal, and the automatic driving controller is used for controlling the electrically-controlled steering device to adjust the travelling direction of the vehicle; the more than two ultra-wideband positioning base stations are arranged at two sides of a planned route, and time synchronization between adjacent ultra-wideband positioning base stations is realized in a wired or wireless network; and an antenna arranged on the ultra-wideband positioning base station is used for receiving the ultra-wide frequency signal sent by the ultra-wideband label for solution and is connected with a solution server via the wireless or wired network to acquire a real-time position and motion information of the vehicle carrying the label. The system of the invention has the advantages of simple structure, convenient control, good reliability and the like.

Description

technical field [0001] The invention mainly relates to the field of urban public transportation equipment, in particular to an automatic driving control system for road vehicles based on an ultra-wideband positioning system suitable for long-formed road vehicles. Background technique [0002] Urban rail transit refers to a special-line public transportation system with continuous guiding capabilities, which is characterized by having a specific track and vehicles running along the track. Common urban rail transit includes subways, light rails, and trams. Among them, subways and light rails are mostly built underground or on viaducts, and they can run freely in special rail lines by using the blocking mode. Although they have a strong transportation capacity, the initial infrastructure and vehicle purchase costs are relatively high, making them unavailable in small and medium-sized cities. application. Trams require a special power system and track coordination design, whet...

Problems solved by technology

Although the passenger car of the articulated car train has a large passenger capacity, the biggest difference between it and the single passenger car is the change of the road passability caused by the lengthening of the body, which is specifically manifested in the increase of the turning radius and the increase of the lane area occupied by the turn. Large, it is easy to interfere with other elements of the road traffic next to it, so that it cannot pass smoothly, or even worsen the traffic operating environment, and it is impossible to realize public transportation quickly and efficiently
