    • On receipt of route information, map data in an area near the route is read (S11). One intersection existing on the route is extracted from the read map data, and intersection-connected links connected to the intersection are extracted (S12). The road widths from the center line to the right and left sides are specified for the intersection-connected links based on attribute data such as the actual road width of the intersection-connected links (S13). New lines are drawn for all the intersection-connected links by translating the line representing the intersection-connected link as the center line rightward and leftward by the specified road widths, to determine right and left side lines of the intersection-connected link (S14).
      Based on the thus-generated width-imparted intersection-connected links, an intersection shape is generated (S15). This processing is repeated for all the intersections concerned (S16). This makes it possible to generate and display intersection shapes based on a road network map having a degree of scale higher than a town map.
    • 在收到的路由信息​​,在路线附近的区域地图数据被读取(S11)。 现有的路线上的一个交叉点,从读出的地图数据中提取,并连接到所述交叉点交叉点连接的链路被提取(S12)。 从中心线向右侧和左侧的道路宽度为基于属性数据的交点相连的链路指定的:如交叉点连接的链路(S13)的实际的道路宽度。 新线通过平移所述线表示的交点连接的链接作为中心线向右绘制所有的交叉点连接的链路和向左由指定的道路宽度,确定性矿右与交点连接的连杆的左场边(S14) , 基于如此生成的宽度赋予交点相连的链路的相交形状生成(S15)。 重复所有有关的交点(S16),该处理。 这使得能够基于具有一定程度的规模比一个镇地图更高的道路网络地图上生成和显示交叉点形状。

    • In an automatic guided vehicle system for guiding a driverless vehicle (10) over a predetermined path of travel without any tracks, wires or the like the vehicle is provided with an active optical navigation section (103) for determining vehicle position and bearing by scanning a plurality of beacons (12 to 24) distributed within the zone of travel of the vehicle, a passive ground navigation section (105) including a gyrocompass (58) for measuring changes in bearing of the vehicle and a wheel encoder (62) for measuring distance travelled by the vehicle's steering wheel. Memory onboard the vehicle contains a series of path vectors which define a predetermined path of travel for the vehicle. The ground navigation section updates vehicle position and bearing as determined by the optical navigation section. A programmed onboard computer (100) includes driver software for generating steering data so as to guide the vehicle over a corrective arc path from its position and bearing, as determined by the navigation sections, to the desired position and bearing as indicated by a stored path vector.
    • 在用于将无人驾驶车辆(10)引导到预定的行进路径上而没有任何轨道,电线等的自动引导车辆系统中,车辆设置有主动光学导航部分(103),用于通过扫描 分布在车辆行驶区内的多个信标(12至24),包括用于测量车辆的轴承变化的陀螺仪(58)的无源地面导航部分(105)和用于测量车辆距离的车轮编码器(62) 由车辆的方向盘行驶。 车辆上的存储器包含一系列路径向量,其定义用于车辆的预定行驶路线。 地面导航部分更新由光学导航部分确定的车辆位置和方位。 编程的车载计算机(100)包括用于产生转向数据的驾驶员软件,以便将导航部分所确定的车辆从其位置和方位导向校正电弧路径到所需的位置和方向,如所存储的路径 向量。
