    • An on-vehicle navigation system having a route searching function for automatically selecting a guiding route to a destination in consideration of run experiences of the user. Run experience data indicative of the run experience is formed every road unit which the vehicle has run and is stored, a plurality of traveling routes which a vehicle can run between a start point and the destination are searched for and weights of the road units in the traveling route and the corresponding run experience data is obtained from memory for each of the plurality of traveling routes in the route searching operation, the weight of each road unit in the traveling route is corrected by the corresponding run experience data for each of the plurality of traveling routes, a sum value of the corrected weights corresponding to the road units in the traveling route is calculated for each of the plurality of traveling routes, and a traveling route of which sum value is the minimum is selected from the plurality of traveling routes. The route including the roads which the user has run previously is preferentially selected as a guiding route, so that a route search which makes the most of the run experience of the user is performed.
    • 一种具有路线搜索功能的车载导航系统,用于考虑到用户的运行体验自动选择到目的地的引导路线。 在车辆运行和存储的每个道路单元上形成表示运行经验的运行经验数据,搜索车辆可以在起点和目的地之间运行的多条行驶路线,并且搜索车辆中的道路单元的重量 在路线搜索操作中,对于多个行驶路线中的每一个,从存储器获得行驶路线和相应的行驶经验数据,行驶路线中的每个道路单元的重量由相应的运行经验数据 对于多个行驶路线中的每一个,计算行驶路线中与道路单位对应的修正权重的和值,并且从多个行驶路线中选择和值为最小的行驶路线。 优先选择包括用户以前运行的道路的路线作为引导路线,从而进行充分利用用户的跑步体验的路线搜索。

    • In a map information display device, the map data extracting unit extracts character data corresponding to characters from map data corresponding to the map, and the map data converting unit converts the map data including no character data to a bird's-eye-view map data. The character data converting unit selects designated character data from the extracted character data and converts the character data other than the designated character data to bird's-eye-view character data. Then, the combining unit combines the bird's-eye-view character data, the bird's-eye-view map data and the designated character data to produce combined bird's-eye-view data. Then, the display unit displays the map of bird's-eye-view using the combined bird's-eye-view data.
    • 在地图信息显示装置中,地图数据提取部从与地图对应的地图数据中提取与字符对应的字符数据,地图数据变换部将不包含字符数据的地图数据变换为鸟瞰图数据。 字符数据转换单元从提取的字符数据中选择指定的字符数据,并将除了指定的字符数据之外的字符数据转换为鸟瞰视角字符数据。 然后,组合单元将鸟瞰视角字符数据,鸟瞰图地图数据和指定字符数据组合,以产生组合鸟瞰数据。 然后,显示单元使用组合的鸟瞰图数据显示鸟瞰图。
