The invention discloses an intelligent vehicle safety situation assessment method considering multi-vehicle interaction. The method comprises the following steps:1, establishing an intention recognition module through a long-short-term memory network; 2, defining logic judgment based on probability maximum classification through the intention recognition module according to the historical track information of the vehicle, and calculating the driving intention probability of the surrounding vehicles of the predicted vehicle; 3, outputting a potential risk by adopting a risk assessment module based on a driving safety field through analyzing the interaction among the driver, the vehicle and the road; 4, establishing a comprehensive situation evaluation model in combination with the driving intentions, calculated by the risk evaluation module and the intention recognition module, of the surrounding vehicles of the predicted vehicle, and outputting a dynamic potential risk map consideringmulti-vehicle interaction in a dynamic traffic scene through the comprehensive situation evaluation model; according to the invention, the dynamic potential risk map considering multi-vehicle interaction can be output, and the calculated risk map allows the intelligent vehicle to evaluate the driving state of the intelligent vehicle by using the real-time risk value so as to perform early warningand take appropriate measures.

    本发明公开了一种考虑多车交互的智能车辆安全态势评估方法,该方法包括:步骤S1,通过长短时记忆网络建立意图识别模块;步骤2,根据车辆的历史轨迹信息,通过所述意图识别模块,定义基于概率最大分类的逻辑判断,计算出被预测车辆的周车的驾驶意图概率;步骤S3,通过分析驾驶人、车辆和道路之间的相互作用,采用基于行车安全场的风险评估模块输出潜在风险;步骤S4,结合风险评估模块和意图识别模块计算得到的被预测车辆的周围车辆的驾驶意图,建立综合态势评估模型,通过所述综合态势评估模型输出动态交通场景下考虑多车交互的动态潜在风险图;本发明能够输出考虑多车交互的动态潜在风险图,计算出的风险图允许智能车辆利用实时风险值来评估其驾驶状态进行提前预警和采取合适措施。
