Overtaking situation awareness early warning system based on Internet of vehicles

Abstract

An overtaking situation awareness early warning system based on the Internet of vehicles relates to the field of vehicle active safety. The objective of the invention is to solve the problems of traffic conflicts and even traffic accidents caused by insufficient environmental perception and inaccurate evaluation before overtaking of vehicles under different driving environment conditions. The system comprises a situation awareness trigger module, an information collection module, a calculation process control module, a fuzzy calculation module, a safety threshold calculation module, a situation awareness calculation module and an early warning information prompt module. The system can predict the overtaking safety in the current environment in an omnibearing manner through the informationof a vehicle, surrounding vehicles, the driving environment and the like acquired in real time. Not only can the driving safety of the vehicle be improved, but also the driving safety of the surrounding vehicles can be improved by information prompting to the surrounding vehicles. Moreover, unnecessary oil consumption can be reduced.

Description

technical field [0001] The invention relates to the field of automobile active safety, in particular to an overtaking situation awareness and early warning system based on the Internet of Vehicles. Background technique [0002] In recent years, with the continuous increase of car ownership, the number of traffic accidents has also continued to rise, and the proportion of traffic accidents caused by improper overtaking is as high as 15%. If the vehicle can comprehensively perceive the surrounding vehicles and driving environment before overtaking and deduce whether it is suitable for overtaking, many traffic accidents caused by improper overtaking can be avoided. The existing overtaking warning systems or methods based on the Internet of Vehicles do not take into account weather conditions, road conditions, and the driving intentions of surrounding vehicles, and these factors have a significant impact on the safe distance between vehicles, so whether it is satisfied The dete...
