Abstract

A navigation device includes a data transmission-reception portion for performing data transmission and reception with a portable terminal, an address list cooperation portion for receiving address list data, a schedule cooperation portion for receiving and managing schedule data, a candidate location specifying information recording portion for searching and extracting information for specifying a location corresponding to one schedule item from the address list data concerning a schedule indicated in schedule data to record the extracted information, a position specifying information obtaining portion for obtaining position specifying information for specifying a position on a map corresponding to each piece of candidate location specifying information, a selecting portion for selecting one position specifying information from position specifying information, and a path managing portion for determining a position of each destination on the path in accordance with the selected position specifying information to manage the path information.

Claims

1. A navigation device that is capable of managing path information, the device comprising:

a data transmission-reception portion for sending and receiving data with a portable terminal;

an address list cooperation portion for receiving address list data from the portable terminal and managing the same;

a schedule cooperation portion for receiving schedule data from the portable terminal and managing the same;

a candidate location specifying information recording portion for searching and extracting information for specifying a location that corresponds to one schedule item from the address list data concerning a schedule indicated in the schedule data and recording the extracted one or more pieces of information as candidate location specifying information;

a position specifying information obtaining portion for obtaining information that specifies a position of a destination or a location on a path that corresponds to each piece of the candidate location specifying information as position specifying information;

a selecting portion for selecting one piece of position specifying information from one or more pieces of position specifying information; and

a path managing portion for determining the position of the destination or the location on the path in accordance with the selected position specifying information and managing the path information.

2. The navigation device according to claim 1, further comprising a position information modifying portion for modifying each piece of the position information of the destination or the location on the path that is managed by the path managing portion in accordance with position specifying information that was not selected by the selecting portion.

3. The navigation device according to claim 1, further comprising a user setting portion for modifying each piece of the position information of the destination or the location on the path that is managed by the path managing portion in accordance with the position specifying information that complies a setting input by a user.

4. The navigation device according to claim 1, wherein the selecting portion calculates a distance between a current position and each position in accordance with each piece of position specifying information and selects position specifying information having the calculated distance that is the smallest.

5. The navigation device according to claim 1, wherein the selecting portion calculates a time that is necessary for traveling from a current position to each position in accordance with each piece of position specifying information and selects position specifying information having the calculated time that is the shortest.

6. The navigation device according to claim 1, wherein the selecting portion calculates a distance between user'"'"'s home and each position in accordance with each piece of position specifying information and selects position specifying information having the calculated distance that is the smallest.

7. The navigation device according to claim 1, wherein the selecting portion selects one piece of position specifying information from among the position specifying information in accordance with a preset priority.

8. The navigation device according to claim 1, wherein the selecting portion selects one piece of position specifying information from among the position specifying information in accordance with past history data.

9. The navigation device according to claim 1, wherein the selecting portion performs conversation with a user using voice about each piece of position specifying information and selects position specifying information in accordance with contents of the conversation.
