The invention discloses a driver driving danger early warning method in an intelligent network connection environment, and the method comprises the steps: obtaining the natural driving data of a driver during each trip under different road types and different traffic flows, and equally dividing each trip into travel segments; calculating characteristic parameters of two bad driving behaviors of overspeed and sudden speed change in each travel segment; determining a bad driving behavior characteristic parameter dynamic safety threshold value, and calculating a bad driving behavior score of the driver; dividing risk levels; obtaining a comprehensive score and a risk level of each travel segment of the driver; and obtaining the comprehensive score and the risk level of the next journey segment of the driver, obtaining the risk early warning intensity, and achieving driving danger early warning. According to the method, more accurate risk assessment is obtained, the problem that driving behaviors have different influence degrees on driving safety is solved, driving danger of a driver is early warned in time, active intervention is carried out, and the traffic safety is improved.
本发明公开一种智能网联环境下驾驶员行车危险预警方法,包括:获取不同道路类型不同交通流下驾驶员每次出行时的自然驾驶数据,并将每次出行均分成行程片段;计算每个行程片段中的超速和急变速两种不良驾驶行为的特征参数;确定不良驾驶行为特征参数动态安全阈值,计算驾驶员的不良驾驶行为得分;划分风险等级;获取驾驶员每个行程片段的综合得分及其风险等级;获取驾驶员下一行程片段的综合得分及其风险等级,得到风险预警强度,实现行车危险预警。本发明获得更精确的风险评估,解决驾驶行为对行车安全产生不同影响程度的问题,及时对驾驶员行车危险进行预警,并进行主动干预,有利于提高交通安全性。
