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.

    一种基于车联网的超车态势感知预警系统涉及汽车主动安全领域。为解决车辆在不同的驾驶环境状况下,可能存在超车前对环境感知不充分、评估不准确,从而导致发生交通冲突甚至交通事故的问题。包括态势感知触发模块、信息收集模块、计算流程控制模块、模糊计算模块、安全阈值计算模块、态势感知计算模块、预警信息提示模块。该系统可以通过实时获取到的本车和周围车辆以及驾驶环境等信息,对当前环境下超车的安全性进行全方位的预测。不仅可以提高本车驾驶的安全性,还能够通过对周围车辆的信息提示,从而提高周围车辆驾驶的安全性。并且能够减少不必要的油耗。
