路线估计器
摘要：
本公开内容作为一个方面提供了一种路线估计器(40)，该路线估计器(40)具有曲率半径估计器(40，S110至S130)、计算器(40，S140)和确定部(40，S150至S210)。曲率半径估计器在不同时间点获得关于在车辆的行驶方向上在车辆前方的前方行驶路径的第一信息，并且基于重复地获得的第一信息来估计相应时间处的前方行驶路径的每个曲率半径。计算器基于前方行驶路径的所估计的曲率半径计算改变信息，该改变信息指示前方行驶路径的曲率半径的时间改变的幅度。确定部基于所计算的改变信息来确定是否存在前方行驶路径的道路形状发生改变的改变点。
摘要（英）：

This disclosure provides as an aspect a course estimator (40) having a curvature radius estimator (40, S110-130), a calculator (40, S140) and a determination section (40, S150-210). The curvature radius estimator obtains first information on a forward traveling path ahead of a vehicle in a traveling direction of the vehicle at different time points and estimating, on the basis of the first information obtained repeatedly, each curvature radius of the forward traveling path at a respective time. The calculator calculates change information indicating magnitude of time change in curvature radius of the forward traveling path on the basis of the estimated curvature radiuses of the forward traveling paths. The determination section determines whether or not there is a changing point where a road shape of the forward traveling paths changes on the basis of the calculated change information.
