The invention relates to an automatic driving safety decision-making method and system fusing a scene evolution knowledge graph and a large language model, and belongs to the field of automatic driving. The method comprises the following steps: acquiring driving data obtained in the driving process of the unmanned vehicle; generating a prompt template of a safety decision model according to the driving data to obtain a behavior decision result; wherein the security decision model is constructed based on a large language model; selecting an example traffic element entity relation graph in the scene evolution knowledge graph based on the driving data, and obtaining probable evolution scene sets and probabilities corresponding to each evolution scene in the scene evolution knowledge graph in combination with the number of time frames required for executing a behavior decision result; judging a risk assessment result of the behavior decision result based on the evolution scene set and the probability corresponding to each evolution scene; and under the condition that the risk assessment result meets the requirement, enabling the unmanned vehicle to execute the decision result. According to the invention, more accurate driving behavior suggestions are provided.

    本公开涉及一种融合场景演化知识图谱和大语言模型的自动驾驶安全决策方法及系统,属于自动驾驶领域。所述方法包括:获取无人车驾驶过程中所获得的行驶数据;根据行驶数据生成安全决策模型的提示模板,以得到行为决策结果;其中,所述安全决策模型基于大语言模型构建;基于行驶数据在场景演化知识图谱中选取一示例交通要素实体关系图,并结合执行行为决策结果所需的时间帧数量,在场景演化知识图谱中获取可能的演化场景集合与每一演化场景对应的概率;基于演化场景集合与每一演化场景对应的概率判断行为决策结果的风险评估结果;在风险评估结果满足要求的情况下,使无人车执行该行决策结果。本发明提出更精确的驾驶行为建议。
