The invention belongs to the technical field of information technology service, and discloses a personalized lane changing decision-making method and system based on a driver psychological risk field model, and the method comprises the steps: S1, perceiving psychological risk data; s2, establishing a driver psychological risk field model, abstracting the influence of the traffic environment and the motion behavior of the interactive vehicle on the psychology of the driver into a psychological risk field, and regarding the force value of the psychological risk field as the quantitative index of the real-time psychological risk; s3, calculating the comprehensive psychological risk of the driver according to the obtained psychological risk assessment result of the driver; s4, calculating a personalized psychological risk threshold according to the driving style data of the driver; and S5, comparing the comprehensive psychological risk of the driver with a personalized psychological risk threshold value to realize a personalized lane changing decision. According to the method, the psychological risk factor of the driver is introduced when the lane changing risk is considered, the influence of the driving environment and the motion behavior of the interactive vehicle on the psychological risk of the driver is analyzed, and the risk assessment is more accurate and humanized.
本发明属于信息技术服务技术领域,公开了一种基于驾驶人心理风险场模型的个性化换道决策方法及系统,包括:S1,心理风险数据感知;S2,建立驾驶人心理风险场模型,将交通环境以及交互车辆的运动行为对驾驶人心理造成的影响抽象为一个心理风险场,心理风险场场力值被视为实时心理风险的量化指标;S3,根据得到的驾驶人心理风险评估结果计算驾驶人综合心理风险;S4,根据驾驶人驾驶风格数据计算个性化心理风险阈值;S5,将驾驶人综合心理风险与个性化心理风险阈值对比,实现个性化换道决策。本发明考虑换道风险时引入驾驶人心理风险因子,分析行驶环境和交互车辆的运动行为对驾驶人心理风险造成的影响,方便对风险评估更加准确,人性化。
