Working method for vehicle collision warning device based on intelligent traffic base station

Abstract

The invention relates to the technical field of intelligent transportation systems, and discloses a working method for a vehicle collision warning device based on an intelligent traffic base station.According to the working method, on one hand, vehicle situations on a main road and a secondary road can be respectively observed by main road vehicle sensing equipment and secondary road vehicle sensing equipment to solve the problem that geographic space limits the vehicle observation, on the other hand, it can be determined whether or not a vehicle collision risk exists on the main road and thesecondary road by performing converging process on vehicle observation results on the two roads through the intelligent traffic base station, if yes, early warning prompt is performed through a secondary road traffic changeable information plate above the secondary road or a wireless early warning signal is transmitted through a road side wireless transmitter-receiver, so that a driver or vehicleautomatic emergency braking module of a vehicle on the secondary road can take steps of braking or deceleration and the like in time to avoid vehicle collision risks, thereby greatly reducing the accident rate at a confluence intersection and ensuring the property and life security of people.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a working method of a vehicle collision warning device based on an intelligent transportation base station. Background technique [0002] The predecessor of Intelligent Traffic Systems (ITS) is Intelligent Vehicle Highway System (IVHS), which is a combination of advanced information technology, data communication technology, sensor technology, electronic control technology and computer technology. Effectively and comprehensively apply to the entire transportation management system, so as to establish a real-time, accurate and efficient comprehensive transportation and management system that plays a role in a wide range and in all directions. Among them, the intelligent transportation base station, as the basic unit in the intelligent transportation system, is widely arranged on the roadside to connect sensors, terminals, vehicles, data centers and c...

Problems solved by technology

When a vehicle is driving on the road and merging, changing lanes, decelerating or accelerating, etc., it usually needs to rely on the driver's observation of the surrounding environment to identify whether it is safe to drive. However, the driver's observation angle in the car is limited, and it is easy to Blind spots in the field of vision make the driver underestimate the situation of the surrounding vehicles, which leads to a greater safety hazard in driving the vehicle

[0004] Although many collision warning devices and methods are currently provided, which can assist the driver to perceive the situation of surrounding vehicles and improve driving safety, these devices are mainly configured on individual vehicles. Due to the limitation of geographical space, it is difficult for the driver and the vehicle-mounted collision warning device to observe the situation of the vehicle on another road (main road or auxiliary road) when merging, making it difficult for the driver to make timely adjustments. Take emergency measures to avoid the risk of vehicle collision
