Active safety early warning device and method based on cooperative vehicle infrastructure and 4G network

Abstract

The invention discloses an active safety early warning device based on cooperative vehicle infrastructure and a 4G network, which comprises a roadside signal integration processing module, a roadside 4G module, a vehicle-mounted 4G module, a vehicle-mounted GPS module and a vehicle-mounted controller module, wherein the roadside signal integration processing module receives information of a traffic signal lamp module, integrates information received by the roadside 4G module and processes the information; the roadside 4G module receives information from the roadside signal integration processing module and outwardly broadcasts the received information and internally-stored information of GPS latitude and longitude coordinates for the central position of an intersection; the vehicle-mounted 4G module communicates with the roadside 4G module; the vehicle-mounted GPS module is used for measuring the position information of the vehicle and sending the information to the vehicle-mounted controller module; and the vehicle-mounted controller module is used for controlling display information of the vehicle-mounted 4G module and a HMI (Human Machine Interface) module, calculating the time when the current vehicle arrives at the intersection and the time difference when detected target vehicles arrive at the intersection respectively, judging whether to reach an alarming threshold and giving a red light running alarm and/or a collision alarm if the corresponding alarming threshold arrives. The cost is low, the structure is simple, and quick early warning is carried out on vehicle collision.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation and road traffic safety, in particular to an active safety early warning device and method based on vehicle-road coordination and 4G network, especially suitable for running red light alarms at intersections with lights and early warnings for blind spots at intersections. Background technique [0002] With the continuous improvement of my country's urbanization rate, there are more and more intersections with line of sight blocking and traffic lights. Although there are signal lights at the intersection, driving safety is significantly improved, but because some drivers have dangerous driving behaviors such as running yellow lights, or large trucks ahead block the line of sight, etc., it still poses a great hidden danger to driving safety. . Moreover, the traditional traffic management method, which considers roads and vehicles as separate systems, has been difficult to meet pe...
