Prompt method, system and server when vehicle passes intersection

Abstract

The invention discloses a prompt method, system and server for vehicles passing through an intersection, wherein the method includes the following steps: the server receives collection information sent by a plurality of vehicles approaching the intersection, wherein the collection information includes traffic light status information, vehicle and The distance information between the traffic lights and the current speed information of the vehicle; and the server calculates the time for each of the multiple vehicles to reach the traffic light or the time required to pass the traffic light based on the collected information, and generates corresponding passing prompt information, and sends the passing prompt information to the corresponding vehicle. The method of the embodiment of the present invention enables multiple vehicles approaching traffic light intersections to receive the corresponding passing prompt information sent by the server, without requiring each vehicle to install a separate set of control systems, which greatly improves the efficiency of traffic while saving resources. user experience.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method, a system and a server for prompting when a vehicle passes an intersection. Background technique [0002] At present, the sharp increase in the number of vehicles has made the traffic environment more complicated, and the number of traffic accidents has also increased, especially at intersections. When the driver cannot accurately judge the state of the traffic lights at the intersection, traffic accidents will occur. To solve this problem, the solution adopted in the related art is: to control the start and stop of the vehicle by identifying the traffic lights. Specifically, the solution collects traffic light signals through a camera located at the front of the vehicle, and analyzes and processes the traffic light signals through an image signal processor, thereby Judging whether the traffic light is on or not and the remaining time, then comparing and analyzing with ...

AI Technical Summary

Problems solved by technology

[0004] 1) The control condition is single, the output control signal is simple, and the intelligent control of the vehicle cannot be realized under complex road conditions;

[0005] 2) This method is only aimed at a single vehicle, and cannot realize the connection between vehicles to realize resource sharing of judging information;

[0006] 3) The amount of information that needs to be judged under complex road conditions is huge, even including information on road conditions and vehicles in front and behind, and each vehicle requires a separate set of control systems, resulting in waste of resources;

[0007] 4) Each vehicle is independently controlled, and unified deployment cannot be accepted, which may easily cause traffic chaos
