The invention belongs to the technical field of vehicle driving, and discloses a vehicle driving strategy generation method and device, electronic equipment and a medium, and the method comprises the steps: generating a decision tree according to vehicle environment information and each vehicle behavior in a vehicle behavior set; each node in the decision tree is generated according to the vehicle environment information corresponding to each time point, and decision branches between the adjacent nodes are generated according to the vehicle behaviors corresponding to the adjacent nodes; evaluating each decision sequence in the decision tree to obtain a driving strategy score corresponding to each decision sequence; each decision sequence is a sequence generated according to a path from a root node in the decision tree to each leaf node; and according to each driving strategy score, selecting a target decision sequence used as a vehicle driving strategy from each decision sequence. In this way, the vehicle driving strategy is selected according to the evaluation result of each decision sequence in the decision tree containing multiple pieces of vehicle environment information and vehicle behaviors, and the accuracy of the driving strategy is improved.

    本申请属于车辆驾驶技术领域,公开了车辆驾驶策略生成的方法、装置、电子设备及介质,该方法包括,根据车辆环境信息以及车辆行为集合中的各车辆行为,生成决策树;决策树中的各节点是根据各时间点分别对应的车辆环境信息生成的,相邻节点之间的决策树枝干是根据相邻节点对应的车辆行为生成的;对决策树中的各决策序列进行评估,获得各决策序列分别对应的驾驶策略评分;各决策序列是根据决策树中的根节点分别到每一叶子节点的路径生成的序列;根据各驾驶策略评分,从各决策序列中,选取用于作为车辆驾驶策略的目标决策序列。这样,根据包含多个车辆环境信息以及车辆行为的决策树中各决策序列的评估结果选取车辆驾驶策略,提高了驾驶策略的准确性。
