移动轨迹预测装置和移动轨迹预测方法
摘要：
本发明的课题在于，即使在车辆产生了摇晃、偏转的情况下，也能根据对象物的位置的历史记录来高精度地预测对象物的移动轨迹。为解决该课题，本发明中，获取车辆周边的对象物的位置(S1)，获取对象物的对地速度(S3)，使用车辆的速度和对象物的对地速度来算出对象物的对于车辆的轨迹预测矢量(相对移动矢量)的倾斜度θ(S7)，用该轨迹预测矢量的倾斜度θ的直线对对象物的位置的历史记录进行拟合(记录的对象物的移动轨迹中的位置的分类)(S8)，将最适合倾斜度θ的直线的位置的倾斜度θ的直线(由通过拟合而分类的组所包含的多个位置决定的直线)预测为对象物的移动轨迹(S9)。
摘要（英）：

An object of the invention is to accurately predict a movement trajectory of an object from a history of positions of the object even in a case where shaking or deflection of a vehicle occurs. In order to achieve the object, in the invention, the position of the object around the vehicle is acquired (S1), a ground speed of the object is acquired (S3), a slope &thetas; of a trajectory prediction vector (relative movement vector) of the object with respect to the vehicle is calculated by using a speed of the vehicle and the ground speed of the object (S7), fitting is performed (classification of the recorded positions of the object in the movement trajectory) with respect to the history of the positions of the object with a straight line having the slope &thetas; of the trajectory prediction vector (S8), and a straight line having the slope &thetas; of the position fitting best in the straight line having the slope &thetas; (straight line having a plurality of positions included in a group classified through the fitting) is predicted as the movement trajectory of the object (S9).
