Early warning method and system for vehicle

Abstract

The invention relates to an early warning method and system for a vehicle. The method comprises the following steps: receiving detection data sent by a detection device, wherein the detection data comprises position information of the vehicle, current motion curve information of the vehicle and speed information of the vehicle; generating request information and sending the request information toa cloud server; receiving the information of traffic lights in front of the vehicle sent by the cloud server, wherein the information of traffic lights in front of the vehicle comprises current statesof the traffic lights, current positions of the traffic lights and remaining time in the current states of the traffic lights; according to the detection data and the information of the traffic lights in front of the vehicle, calculating actual time that the vehicle gets through the traffic lights; calculating the difference value between the actual time and the remaining time in the current states of the traffic lights, and if the difference value is greater than preset time, controlling a warning indicator to send out first warning information. The obtained information of the traffic lightsis not influenced by external environment through the cloud server, and reserved time is set, so that a driver has time to take corresponding measures.

Description

technical field [0001] The invention relates to the technical field of vehicle monitoring, in particular to a vehicle early warning prompting method and system. Background technique [0002] With the continuous development of the automobile industry and the continuous improvement of people's living standards, automobiles have gradually become a necessity for families. Traffic safety has increasingly become a focus of human society. The traffic light control system is one of the important auxiliary systems of the modern traffic management system. It is mainly used to coordinate the orderly and smooth passage of traffic in different directions, thereby reducing traffic congestion and ensuring driving safety. has huge implications for transportation. Therefore, traffic lights are all arranged at most traffic intersections, which makes the driver need to constantly judge the state of the traffic lights when driving, and control the driving of the vehicle according to the state ...

AI Technical Summary

Problems solved by technology

[0003] When driving a car through a traffic light intersection, the driver manually judges whether it is safe to pass according to the remaining time prompted by the traffic light. This method is prone to the risk of running a red light, especially for novice drivers, causing car accidents

Behaviors such as vehicles running red lights have caused serious traffic safety hazards, and sometimes even lead to major accidents

Some drivers ignore the traffic safety and intentionally run the red light, and some drivers mistakenly think that the vehicle can still pass through the green light due to miscalculation of the time and distance when the green light is about to end. Red light, and now the traffic management is becoming more and more strict. The latest traffic regulations for running a red light will deduct 6 points, that is, a driver’s license can’t be used if it runs a red light once.

The existing technology is to obtain the distance between the traffic light and the remaining time of the traffic light through the camera device, and judge whether the vehicle can pass through the traffic light intersection according to the remaining time of the traffic light and the speed of the vehicle, but the camera device in the control device is relatively limited If there are other vehicles blocking the vehicle in front of it or in heavy fog, it is difficult to calculate the distance between the vehicle and the traffic light based on the captured video image information, and it is impossible to judge whether it can pass before the red light is on, and the judgment is not accurate enough , can not play a good role as a reminder
