The map data of the corresponding area is read, and after the data processing, the current position of the vehicle is displayed on a display device such as a liquid crystal display.

[0003] Conventionally, a navigation system having communication means such as the Internet is known.

[0004]

A navigation system having communication means such as the Internet can receive event information and the like from the Internet, but there is no system that can send and receive personal position information.
Basically, personal information only has a terminal ID, that is, an idea of a fixed station such as a house, and there is no navigation system that knows the position information of a moving communication partner.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to provide a navigation system capable of displaying respective positions on a map while moving each other.

[0006]

Means for Solving the Problems (1) The present invention has a position detecting means for detecting the position of a moving object, and a storage / reproducing means for storing and reproducing map data and related data. , The position of the detected moving body,
In a navigation system that is reproduced by the storage and reproduction means and displayed on a map corresponding to the detected position, the position information of the moving object detected by the position detection means is transmitted to a communication partner, and the position from the communication partner is determined. Providing communication means for receiving information, displaying the position of the communication partner on a map based on the received position information from the communication partner and data stored in the storage / reproduction means, The position information is communicated in a set predetermined format, and the communication means further communicates guidance information, and a communication partner position is determined based on the guidance information and data stored in the storage / reproduction means. It is characterized in that a route to the route is guided and displayed on the map.

(2) When the position information of the communication partner is received via communication means such as a mobile phone and the Internet, the position of the communication partner is determined based on the received information and the data stored in the storage / reproduction means. Is displayed on the map. When the guidance information is received, the route to the communication partner position is guided and displayed on the map.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a system configuration of an embodiment in which the present invention is applied to an automobile, and 1 is a GPS antenna (a part of a position detecting means) for receiving a radio wave from an artificial satellite. Reference numeral 2 denotes a CD-ROM player (storage / reproducing means) for storing map information and reproducing the data. Reference numeral 3 denotes a modem (modulator / demodulator) for exchanging information with the outside, and reference numeral 4 denotes a general portable telephone (communication means). The mobile phone 4 is connected to, for example, the Internet for exchanging e-mail.

Reference numeral 5 denotes a GPS signal processing unit which comprises a board of an aggregate of a plurality of CPUs and memories and controls the system in an integrated manner. This GPS signal processing unit 5
While receiving the map information from the CD-ROM player 2, it calculates the position of the vehicle based on the information from the artificial satellite received by the GPS antenna 1, synthesizes the information, and displays the information on a liquid crystal display or the like. The device 6 has a function of expressing display information by a graphic. The GPS signal processing unit 5 also has a memory for storing user information such as a running locus and a mark. Reference numeral 7 denotes a remote controller for operation as operation means such as keys for operating each unit.

Next, the operation of the system configured as described above will be described with reference to the diagram showing the display screen of FIG. 2 and the flowchart of the GPS signal processing section 5 of FIG. First GPS
The GPS signal processor 5 reads the map data of the corresponding area stored in the CD-ROM player 2 based on the detected position information of the vehicle received by the antenna 1 and, after the data processing, displays the map data on the display device 6 automatically. The current position of the car is displayed as shown in FIG.

The e-mail sent via the Internet and the mobile phone 4 is displayed on the display device 6 as shown in FIG. At this time, the latitude / longitude information as the position information is determined in advance in the communication format when sending the e-mail as in the following example. Example shinada @ m
e.sony.co.jp [## '. ## / ##. ##] and the receiver reads the latitude / longitude from this [##'. ## / ##. ##] format and communicates. The location of the other party is displayed as shown in FIG.

Further, the route between the own vehicle position and the communication partner position can be guided and displayed as shown in FIG. 2C. That is, when the guidance information is received, the GPS signal processing unit 5 calculates the route based on the map information stored in the CD-ROM player 2, and displays the route as shown in FIG.

The guide route is a CD-ROM player 2.
The data may be calculated and displayed based on not only the above data but also, for example, traffic information superimposed on FM multiplex broadcasting.

The electronic mail may be sent and received by voice input by a voice recognition device in addition to key input.

[0015]

As described above, according to the present invention, communication means for transmitting position information of a moving object detected by the position detecting means to a communication partner and receiving position information from the communication partner is provided. Based on the location information from the communication partner and the data stored in the storage / reproduction means,
Since the position of the communication partner is configured to be displayed on a map, the communication can evolve from words to letters and into figures, allowing each position to be displayed on the map as they move. Periodic things can be realized.
