The invention provides a driving risk assessment method and system based on a human-vehicle-road coupling model. The method comprises the following steps: establishing a driver risk entropy model based on a driver historical state and an instantaneous state; establishing a pedestrian risk entropy model and a vehicle risk entropy model based on the basic equal-altitude risk elliptical line and the right half normal distribution density function; establishing a road risk entropy model based on the segmented normal density function; and based on the risk entropy model of the driver, the pedestrian, the vehicle and the road, obtaining the driving risk entropy, thereby carrying out driving risk assessment based on human-vehicle-road coupling in a dynamic complex environment. According to the invention, real-time evaluation of the driving risk situation in a complex driving environment is realized, and a foundation is laid for improving driving safety.

    本发明提供了一种基于人‑车‑路耦合模型的行车风险评估方法和系统,包括以下步骤:基于驾驶员历史状态与瞬时状态建立驾驶员风险熵模型;基于基本等高风险椭圆线与右半正态分布密度函数建立行人风险熵模型与车辆风险熵模型;基于分段正态密度函数建立道路风险熵模型;基于驾驶员、行人、车辆和道路的风险熵模型,获取行车风险熵,从而进行动态复杂环境下基于人‑车‑路耦合的行车风险评估。本发明实现了复杂驾驶环境下行车风险态势的实时评估,为提高行车安全性奠定基础。
