According to the safe driving assistance system based on human, road and environment dynamic coupling, a dynamic coupling subsystem takes a driver, a vehicle, a road and an environment as a characteristic index set of driving danger prediction to construct a driving danger regression prediction model based on a BP neural network; predicting the danger to be encountered in the driving process of the driver through the driving danger regression prediction model, judging the danger level, and adopting an early warning scheme of the corresponding level; the third-level early warning subsystem performs a third-level early warning scheme according to danger level prediction, and the third-level early warning scheme comprises voice early warning, emergency contact person contact and automatic positioning alarm; in the early warning tracking subsystem, early warning tracking is adopted after third-level early warning is carried out on the driver, and the early warning tracking content comprises the response of the driver to third-level early warning and whether corresponding driving decision behaviors are adopted or not. According to the method, the comfort and safety of automobile driving are effectively improved, the number of traffic accidents is reduced, and basic guarantee is provided for social public safety.
基于人、道路、环境动态耦合的安全驾驶辅助系统,其中,动态耦合子系统以驾驶员、车辆、道路和环境作为行车危险预测的特征指标集,构建基于BP神经网络的行驶危险回归预测模型,通过行驶危险回归预测模型预测驾驶员行驶过程中即将遇到的危险,并判断危险级别及采取对应等级的预警方案;三级预警子系统根据危险等级预测进行三级预警方案,三级预警方案包括语音预警、联系紧急联系人和自动定位报警;预警追踪子系统中,当对驾驶员实行三级预警后采取预警追踪,预警追踪内容包括驾驶员对三级预警的反应,及是否采取相应的驾驶决策行为。本发明有效提升汽车驾驶的舒适性与安全性,减少交通事故发生次数,为社会公共安全提供基础保障。
