摘要： The system of the present invention provides easy update of a database containing a large amount of data arranged in a complicated interrelationship by use of a data file of a content limited to data differing from that already in the database, within a relatively short period of time. The system includes a navigation apparatus having a local storage database which contains, updated by a difference data file, a plurality of data groupings. The navigation apparatus determines conversion priority according to the operational state of an operation program and converts data in a local storage database to a referential data format in the order of the determined conversion priority. The system also includes a server apparatus for outputting the difference data file to the navigation apparatus.
摘要翻译：本发明的系统通过在相对较短的时间段内使用限于数据库中不同于数据的数据的数据的数据文件，提供包含以复杂相互关系排列的大量数据的数据库的容易的更新。该系统包括具有本地存储数据库的导航装置，其包含由差分数据文件更新的多个数据分组。导航装置根据操作程序的操作状态确定转换优先级，并按照确定的转换优先级的顺序将本地存储数据库中的数据转换为参考数据格式。该系统还包括用于将差异数据文件输出到导航装置的服务器装置。

摘要： A navigation device that is provided with reference databases that include search databases that are referenced when the navigation device performs a location search for a location on a map, that accepts provided update data, and that performs update processing for the reference databases is provided with a priority processing unit that, in a case where a command to perform the location search is input during the update processing for the reference databases, gives priority to performing the update processing for location data that are stored in the search databases, as well as with a search unit that, after the update processing for the location data is completed by the priority processing unit, is enabled to perform the location search using the updated location data.
摘要翻译：提供了参考数据库的导航装置，该导航装置包括当导航装置执行对地图上的位置的位置搜索，接受所提供的更新数据以及对参考数据库执行更新处理时引用的搜索数据库，优先处理单元，在对参照数据库的更新处理中输入了执行位置搜索的命令的情况下，优先执行存储在搜索数据库中的位置数据的更新处理，以及使用搜索单元，在通过优先处理单元完成位置数据的更新处理之后，能够使用更新的位置数据执行位置搜索。

摘要： A vehicle navigation apparatus determines whether or not the currently traveled route having a current vehicle position matches with estimated routes after determining, on the basis of the traveled route history, the estimated routes which correspond to destination candidates. Then, the navigation apparatus further determines whether or not the subsequent portion of the estimated route overlaps with other estimated route, for selecting one of the destination candidates. The vehicle navigation apparatus thus selects the destination candidate, in a highly accurate manner in terms of user preference, based on the traveled route history.
摘要翻译：在根据所行进的路线历史确定与目的地候选对应的估计路线之后，车辆导航装置确定当前车辆位置的当前行驶路线是否与估计路线匹配。然后，导航装置进一步判定估计路由的后续部分是否与其他估计路由重叠，以便选择一个目的候选。因此，车辆导航装置基于所行进的路线历史以高度准确的方式选择用户偏好的目的地候选。
