The invention discloses a multi-modal analysis method for trajectory data of an automatic driving vehicle. The method comprises the following steps: step 1, obtaining an instantaneous line quantity and an instantaneous angular quantity of each vehicle; and step 2, establishing Gaussian distribution functions of the instantaneous linear quantity and the instantaneous angular quantity, and determining a motion mode of each vehicle based on a relationship between a data mean value and a variance in the Gaussian distribution functions of the instantaneous linear quantity and the instantaneous angular quantity. According to the method, the motion behaviors of the vehicle can be classified under different conditions, and accurate and reliable data support is provided for key technologies such as path planning and control decision making of an automatic driving system.

    本发明公开了一种自动驾驶车辆轨迹数据多模态分析方法,包括以下步骤:步骤1、获取每个车辆的瞬时线量和瞬时角量;步骤2、建立瞬时线量和瞬时角量的高斯分布函数,基于瞬时线量和瞬时角量高斯分布函数中数据均值和方差之间的关系,确定每个车辆的运动模态。本发明方法能够在不同条件下对车辆的运动行为进行分类,为自动驾驶系统的路径规划、控制决策等关键技术提供准确可靠的数据支持。
