A method for assisting safe driving on special road sections based on vehicle-road coordination

Abstract

A special section safe driving auxiliary method based on vehicle and road synergy comprises the following steps that firstly, a road side unit periodically broadcasts special section information to vehicles within a communication covering range; secondly, whether the environment brightness is lower than a first preset value or not is detected; thirdly, vehicle state information within a road side unit range and a covering rage of a special section are acquired; fourthly, whether the driving direction of a vehicle and the direction of the special section to be entered are identical or not is judged; fifthly, a driver of the vehicle is reminded that he / she will enter the special section; sixthly, the driver of the vehicle is reminded to correctly use headlamps; seventhly, whether the speed of the vehicle exceeds the limiting speed or not is correspondingly judged according to the type of the vehicle; eighthly, whether the headlamps are used correctly or not is judged; ninthly, whether the vehicle pulls out of the special section or not is judged. At the vehicle and road synergy information interaction state, the section information is given in advance, whether the vehicle enters or leaves the special section is accurately judged, early warnings in forms of word, voice and the like are given when the vehicle is driven to the special section, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a method for assisting safe driving on special road sections based on vehicle-road coordination. Background technique [0002] The Internet of Vehicles is through the Internet technology, all vehicles can transmit various information of themselves to the central processing unit. Through computer technology, the information of these large numbers of vehicles can be analyzed and processed to calculate the best routes for different vehicles, issue reports on road conditions and adjust signal light cycles. [0003] The vehicle-to-road collaboration technology V2X of the Internet of Vehicles includes the interconnection of vehicles and vehicles (V2V), vehicles and roads (V2I, Vehicle to Infrastructure), vehicles and people (V2P), vehicles and centers (V2C), etc. Communication and roaming between various heterogeneous networks guarantee real-time performance, serviceability and net...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the existing anti-glare technology in special road sections such as sharp bends, slope roads, narrow bridges, narrow bridges, or intersections without traffic signal lights, the drivers on the opposite side are blinded by the high beam lights, and the visibility is reduced. It is very low that you can’t see the road conditions clearly, and you can’t dodge enough to cause traffic accidents. This invention proposes a safe driving assistance method for special road sections based on vehicle-road coordination
