The invention discloses a construction method and device of a vehicle lane changing model, and relates to the technical field of automatic driving. According to the specific scheme, the method comprises the steps that M sets of lane changing data of a vehicle in a manual driving scene are obtained, each set of lane changing data is used for indicating data of the vehicle during lane changing every time, each set of lane changing data comprises values of N kinds of driving attributes, M and N are integers larger than 1, and according to the value of each kind of driving attribute included in each set of lane changing data, N is an integer larger than 1; and determining a first decision-making tree model according to the driving attributes of the vehicle and a preset range corresponding to each driving attribute, and determining a fusion lane changing model according to the first decision-making tree model and a pre-stored second decision-making tree model, the fusion lane changing model being used for lane changing decision of the vehicle in the automatic driving scene. According to the method, the personification degree of automatic driving of the vehicle is improved, and the experience feeling of passengers in the automatic driving process of the vehicle is improved.
本发明公开一种车辆变道模型的构建方法及装置,涉及自动驾驶技术领域。具体方案包括:获取车辆在手动驾驶场景中的M组变道数据,其中,每组变道数据用于指示车辆每次变道时的数据,每组变道数据包括N种行驶属性的值,M和N为大于1的整数,并根据每组变道数据包括的每种行驶属性的值,以及每种行驶属性对应的预设范围,确定第一决策树模型,且根据第一决策树模型和预存的第二决策树模型,确定融合变道模型,融合变道模型用于车辆在自动驾驶场景中的变道决策。本发明提高了车辆自动驾驶的“拟人化”程度,提升了车辆自动驾驶过程中乘客的体验感。
