The invention relates to the field of vehicle early warning, and discloses a dangerous vehicle early warning system and method based on V2X. The dangerous vehicle early warning system based on V2X comprises an information acquisition module which acquires information of a vehicle and information of surrounding vehicles in a preset range, and the information comprises vehicle condition information, driver information and driving state information; the dangerous vehicle identification module is used for creating a dangerous vehicle identification model to calculate a dangerous value of a dangerous vehicle, specifically W = sigma (Ki + Ji + Xi), endowing each of the vehicle condition information, the driver information and the driving state information with a weighted value, accumulating the weighted values when danger exists so as to respectively obtain corresponding danger coefficients, obtaining the dangerous value of the dangerous vehicle through the dangerous vehicle model, and outputting the dangerous value of the dangerous vehicle through the dangerous vehicle model. When the danger value exceeds the threshold value, the vehicle is identified as a dangerous vehicle; and the early warning module is used for generating dangerous vehicle early warning when the identification module identifies the dangerous vehicle. According to the invention, the dangerous vehicle can be accurately acquired, so that the early warning accuracy is improved, and sudden dangers are reduced.
本发明涉及车辆预警领域,公开了一种基于V2X的危险车辆预警系统及方法。基于V2X的危险车辆预警系统,包括:信息获取模块,获取本车的信息及预设范围内周围车辆的信息,所述信息包括车况信息、驾驶人员信息和行驶状态信息;危险车识别模块,创建危险车识别模型计算危险车的危险值,具体为:W=∑(Ki+Ji+Xi),将车况信息、驾驶人员信息和行驶状态信息中的每一项赋予权重值,当危险存在时便累加权重值以分别得到对应危险系数,通过危险车模型获取危险车的危险值,当危险值超过阈值时,识别为危险车;预警模块,当识别模块识别到危险车时,则生成危险车辆预警。本申请能够对危险车辆精准获取,以提高预警的准确性,减少突发危险的产生。
