    • Vehicle control data is stored in a database of a vehicle control information storage apparatus of the present invention by a unit of road segment. When the same vehicle travels the same road segment for plural times, vehicle speed is averaged for storage as the vehicle control information in the database. Further, learning data has a value that is smaller than a threshold for the segment next to a current segment with a fulfillment of other conditions, the data is combined before storage in the database, thereby achieving a smaller storage volume in the database for the same amount of control information.
    • 车辆控制数据以路段为单位存储在本发明的车辆控制信息存储装置的数据库中。 当同一车辆行驶相同的道路段多次时,车速被平均以作为数据库中的车辆控制信息进行存储。 此外,学习数据的值小于具有其他条件的当前段的旁边的段的阈值,则数据在数据库中存储之前被组合,从而在数据库中实现较小的存储量 控制信息量。

    • An absolute position detector of a navigation device detects an absolute position of a vehicle. An on-map position of the vehicle is acquired based on the detected absolute position to be on a road map indicated by map data stored in the navigation device. Absolute positions detected by the absolute position detector are stored in association with on-map positions acquired based on the detected absolute positions as travel track information when the vehicle travels. An error of the map data as a reliability degree of the map data is set by comparing the travel track information with the map data.
    • 导航装置的绝对位置检测器检测车辆的绝对位置。 基于检测到的绝对位置来获取车辆的地图上位置,该绝对位置将位于由存储在导航装置中的地图数据所指示的路线图上。 与绝对位置检测器检测到的绝对位置相关联地存储在基于检测到的绝对位置的地图上位置作为车辆行驶时的行驶轨道信息。 通过将行驶轨道信息与地图数据进行比较来设定地图数据作为地图数据的可靠度的错误。

    • A power consumption recording apparatus is provided that can perform the following for multiple travels of a section traveled by the vehicle. The apparatus can detect as many power consumption events used by the vehicle as the multiple travels. When the vehicle has traveled a given section, the apparatus detects time attributes and occupant counts for the multiple travels. The apparatus divides the power consumption events detected for the section into groups based on power consumption magnitudes. For each group, the apparatus can record a representative power consumption of power consumption events belonging to the group, a time attribute and an occupant count corresponding to occurrence of the power consumption belonging to the group, and the number of occurrences of respective power consumption events, in association with each other.
    • 提供了能够对由车辆行驶的部分的多个行进执行以下操作的功率消耗记录装置。 该装置可以在多个行进时检测车辆使用的尽可能多的功率消耗事件。 当车辆行驶在给定的部分时,该装置检测多次行驶的时间属性和乘员计数。 该装置基于功率消耗量将该部分检测到的功耗事件分成组。 对于每个组,装置可以记录属于组的功率消耗事件的代表性功耗,对应于属于该组的功率消耗的发生的时间属性和乘员数,以及各个功耗事件的发生次数 ,相互联系。
