Next, the operation of the embodiment configured as described above will be described.

First, the driver presses the first switch 20. As a result, the first transceiver 18 is operated, and a radio wave Wc modulated by a line connection code or the like is transmitted from the second antenna 16, and this radio wave Wc is transmitted to the third antenna of the vehicle-mounted facility A. It is received by the second transceiver 42 via 40. In this way, a wireless line is connected to the destination guidance wireless station equipment B.

Then, the first microphone transmits the transmission of destination information such as the name or address of the building at the destination desired by the driver.
24 (or handset 25). Thereafter, the radio wave Wc in which the content of the transmission is modulated is transmitted via the first transceiver 18 and the second antenna 16.

This radio wave Wc is received by the third antenna 40 of the destination guidance radio station equipment B, and subsequently, the second transmitter / receiver 42 demodulates the transmission contents of the driver. The contents of the demodulated destination information are provided to the operator of the destination guidance radio station equipment B by the second.
The voice is transmitted by the speaker 44 of.

Here, the operator inputs the destination information desired by the driver to which the voice is transmitted, on the keyboard 50. The search unit 48 in which the destination information is input searches for the latitude and longitude corresponding to the destination information such as the building name and the street address, and obtains the position information of the destination obtained here, that is, the latitude and longitude. The digital signal is transmitted to the second transceiver 42. The second transceiver 42 transmits the radio wave Wb modulated by the digital signal of the location information of the destination via the third antenna 40.

Next, the radio wave Wb received via the second antenna 16 is fetched into the control unit 28 by a digital signal of latitude and longitude corresponding to the destination information demodulated by the first transceiver 18. Subsequently, the digital signal is supplied to the first memory 26 and stored. When this storage is completed, the wireless line between the first transceiver 18 of the on-board equipment A and the second transceiver 42 of the destination guidance wireless station equipment B is cut off. In this case, the disconnection of the wireless line is performed by transmitting a control signal Sc from the control unit 28 to the first transceiver 18. In the case of a public line, the disconnection of the wireless line is performed by a well-known connection / disconnection operation.

In this manner, when the digital signal of the latitude and longitude corresponding to the destination information of the inquiry is stored in the first memory 26, the control unit 28 outputs the digital signal from the map information stored in the second memory 32. The map information corresponding to the position of the destination is read and output to the display unit 34, and the values of the latitude and longitude of the destination are output. In this case, the display 34 displays a map corresponding to the destination and superimposes an X mark on the position of the destination. Next, when the driver needs to confirm the position of the own vehicle, the driver presses the second switch 30.

In this case, from the GPS positioning device 12, the position of the vehicle measured by receiving a plurality of radio waves Wa, that is, a positioning signal Sa indicating the value of latitude and longitude is output to the control unit 28, and the positioning signal The controller 28 to which Sa is supplied selects and reads out the map information corresponding to the position of the own vehicle measured from the road map information stored in the second memory 32. Further control unit 28
Then, an arrow is superimposed on the longitude and latitude points, which are the positions of the own vehicle measured on the read map. Further, an X mark is superimposed on the destination information signal Sb stored in the first memory 26, that is, the latitude and longitude points related to the position information of the destination.
However, when the position of the destination is outside the screen, it is not displayed. The superimposed signal is output to the display 34, the position of the own vehicle is indicated by an arrow on the map, and an image display in which an X mark is superimposed on the position of the destination is automatically performed.

When the driver wants to confirm the X mark at the destination again, the driver presses the switch 30 again. Here, an image of a nearby map is displayed together with an X indicating the position of the destination on the display 34. By continuously operating the second switch 30 in this manner, since the destination is relatively far away, X of the position of the destination is set.
When the mark and the arrow indicating the position of the moving vehicle cannot be confirmed in one display image, the driving image can be displayed by alternately switching the display image accompanying the traveling of the own vehicle and the display image near the destination. The user can easily select the driving road, etc., and
You can confirm.

In this way, it is not necessary to add an optical disk filing device for storing destination information relating to the name or address of a building having a huge storage capacity to the vehicle-mounted equipment. The miniaturization is easily achieved, the image display of the position of the destination desired by the driver is automatically and easily performed, and operations other than driving during driving are reduced.

In this embodiment, one base station and one mobile station have been described. However, a plurality of mobile stations can operate in the same manner as described above. Further, the positioning device 12 of the own vehicle is not limited to the GPS, and for example, other position measuring means such as an urban transportation system may be used. In addition, in the vehicle-mounted facility A, when a mark is superimposed on the position of the destination on the map, this is automatically performed by obtaining the destination information signal Sb, but the image is displayed only at a time desired by the driver. The present invention also includes providing a selecting means in order to display an image at a desired time using a switch or the like provided here.
