Abstract

An automobile navigation apparatus, that has a rewritable recording medium and capability to updates the map data base by obtaining latest map data, records the map data in the recording means and comprises updating data acquisition means that acquires updated data of a map to which updating procedure is added, an information interpreting means that interprets the updating procedure information, and a map data updating means that searches over said map data base and updates said map data base on the basis of the results of such interpretation and manages the map data by using attributions that indicates additional information of the map elements which are composed into a table as the records thereof so that the row record of the table is classified by the attribution which indicates the additional information of the map element.

Claims

1. A automobile navigation apparatus comprising;

a map data base storing map data in a rewritable memory means,

a map data management means that classifies said map data into attributions of information properties characterized by said map data and composes tables including said attributions which are specified in records thereof and enables to access said map data in a unit of said records,

an updating data acquisition means that acquires updated data of a map to which updating procedure is added,

an information interpreting means that interprets the updating procedure information,

and a map data updating means that updates said map data base based on a result obtained by said information interpreting means,

wherein said updating procedure includes updating condition, updating actions such as deleting, adding and content modification and order of updating steps thereof.

2. An automobile navigation apparatus according to claim 1, including an input means that inputs user subjective information, wherein

said updating data acquisition means acquires map data which is to be updated in accordance with said user subjective information input by said input means, and

said map data updating means updates said map data base after selecting acquired map data under a predetermined condition.

3. An automobile navigation apparatus according to claim 1 including an updating recapitulation recording means that records updating recapitulation of said map data and recording updating recapitulation information such as updating date in said updating recapitulation recording means in corresponding to area information and location information of map elements which are subjective to updating.

4. Server equipment comprising;

a map data base which records map data including evaluation values that are computed by a predetermined set or plural sets of user subjective information and assigned to corresponding map elements and a communication means to transmit/receive data to/from a terminal device, wherein

said server equipment receives user subjective information and transmits map data, which is obtained by searching over map data base under a retrieval condition to which said user subjective information is set, to a terminal device with appending data updating procedure information.

5. Server equipment comprising;

a map data base which records map data including evaluation values that are computed by a predetermined set or plural sets of user subjective information and assigned to corresponding map elements and a communication means to transmit/receive data to/from a terminal device, wherein

said server equipment receives evaluation value and transmits map data, which is obtained by searching over map data base under a retrieval condition to which said evaluation is set, to a terminal device with appending data updating procedure information.
