    • This invention provides a vehicle cruise control system which, during recognition of a shape of a road extending in a frontward direction of host vehicle, can calculate the road shape rapidly and accurately from a positional relationship with respect to the host vehicle. The system includes at least: a position change detector that detects, from information on the road existing in the frontward direction of the vehicle, a horizontal distance from a line segment orthogonal to a traveling direction vector of the vehicle, to a centerline of the road, the detection being conducted at a plurality of measuring points in an extending direction of the traveling direction vector; a road shape recognizer that identifies the shape of the road from data relating to linearity of changes in each of the horizontal distances, the linearity data being obtained by the position change detector; and a cruise controller that controls traveling of the vehicle according to results of the identification by the road shape recognizer.
    • 本发明提供一种车辆巡航控制系统,在识别到在主车辆的向前方向上延伸的道路的形状时,能够从相对于本车辆的位置关系快速,准确地计算道路形状。 该系统至少包括:位置变化检测器,其从车辆前方存在的道路上的信息中检测出与从车辆的行进方向矢量正交的线段的水平距离到道路的中心线 检测在行进方向矢量的延伸方向上的多个测量点进行; 路线形状识别器,其通过与位置变化检测器得到的线性数据相关的水平距离各变化的线性度的数据来识别道路的形状; 以及巡航控制器,其根据道路形状识别器的识别结果来控制车辆的行驶。
