A transmitting station for transmitting specific information consisting of unique information by radio, a receiving unit for receiving the transmitted specific information, and displaying a position of the transmitting station on a map displayed on a display unit based on the received specific information. And a navigation system mounted on the vehicle.

Here, the specific information transmitted from the transmitting station is received by the receiving means of the navigation device, and the transmitting station is displayed on the display map of the display means by the control of the arithmetic processing means using the received specific information. The position of is displayed.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating the principle of the present invention.

The navigation system of the present invention shown in FIG. 1 transmits specific information including its position information and unique information from a transmitting station 1 by radio, and transmits the transmitted specific information to a navigation device 2 mounted on a vehicle. And the arithmetic processing means 2b displays the position of the transmitting station 1 on a map displayed on the display means 2c using the received specific information.

FIG. 2 is a block diagram of a navigation system according to an embodiment of the present invention. However, in the embodiment shown in FIG. 2, portions corresponding to the respective portions of the conventional example in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted.

A navigation device 30 mounted on an automobile shown in FIG. 2 is a feature element of the present embodiment in addition to the operation unit 11, the memory medium 13, the GPS receiver 14, and the display unit 15 described in the conventional example. An antenna 31, a receiver 32,
It is provided with a CPU 33.

A transmitting station 40 shown in FIG. 2 is a characteristic element of the present embodiment in addition to the above-mentioned characteristic elements, and transmits specific information such as a store location and commercials by FM multiplex broadcast radio waves. It is. For example, it is installed in a convenience store having many branches, and is configured to transmit the location of the store, commercials of product information, and the like by FM multiplex radio waves.

In an area where stores are crowded, the FM multiplex radio wave is transmitted from the transmitting station 40 such that a radius of several km is a radio wave area in which radio waves can be received. Is to be sent.

An antenna 31 of the navigation device 30 receives the FM multiplex radio wave and transmits it to a receiver 32.
, Performs decoding processing and data conversion processing, and sends the data to the CPU 33.

The CPU 33 displays the input store specific information on the map read from the memory medium 13 and displayed on the display unit 15 together with the own vehicle position. This display is performed by a symbol, a character, a picture, or the like, or by color-coding and blinking the symbol if it is the store position.

Further, commercial information of the store is displayed on the same map as characters, illustrations, and the like. Alternatively, when the user of the navigation device 30 touches the store position symbol or the like displayed on the display unit 15 with his / her hand, a commercial is displayed on another screen.

Further, the CPU 33 detects the position of the store displayed on the map of the display unit 15 and the position of the own vehicle, and performs control for displaying the shortest route therebetween on the map. The operation of the navigation system having such a configuration will be described with reference to FIG. FIG. 3 is a diagram illustrating the operation of the navigation system according to the present embodiment.

As shown in FIG. 3, for example, a transmitting station 40a installed in a certain store has a radio wave area 5 having a radius of several km.
1 and the transmitting station 40b installed in another store is
It is assumed that a radio wave area 52 having a radius of several tens km is formed. In this case, it is assumed that the car 61 is traveling in the radio wave area 51, the car 62 is traveling in the radio wave area 52, and the car 63 is traveling outside the radio wave areas 51 and 52. Furthermore,
It is assumed that the vehicles 61 to 63 are in a state where the power of the navigation device 30 is turned on.

Under such circumstances, the navigation device 30 of the car 61 automatically receives the FM multiplex radio wave on which the specific information transmitted from the transmitting station 40a is superimposed. Then, the CP on the display unit 15 of the navigation device 30 is displayed.
Under the control of U33, the specific information of the store where the transmitting station 40a is installed is automatically displayed.

That is, the location of the store is displayed on the map displayed on the display unit 15 with, for example, a blinking symbol so that it can be determined as the location of the vehicle. Also, commercial information of the store is displayed on the same map as characters, illustrations, and the like. Further, under the control of the CPU 33, the shortest route from the own vehicle position to the store position is displayed on the map of the display unit 15.

The navigation device 30 of another car 62 is
The radio wave transmitted from the transmitting station 40b is automatically received, and the display unit 15 displays the specific information of the store where the transmitting station 40a is installed and the shortest route to the store. Further, since the car 63 is out of the service area, the transmission radio waves of the transmitting stations 40a and 40b cannot be received, and only the own vehicle position is displayed on the display unit 15.

According to the above-described embodiment, the navigation system transmits the specific information by the FM multiplex radio wave to the transmitting station 40, automatically receives the radio wave to display the specific information, and displays the specific information. And a navigation device 30 for displaying the shortest route from the to the transmitting station 40.

Thus, when a car enters the transmission radio wave area of the transmitting station 40, if the on-vehicle navigation device 30 is turned on, the specific information broadcast by the transmitting station 40 is automatically displayed. Can be.

[0026] Thus, as in the prior art, when the telephone number is not known or the connection to the Internet is required, as in the case where the mobile phone is connected to the navigation device and the specific information is received from the Internet, the information is required in many steps. It does not take time to take in information to obtain the information, nor does it cost money to use the telephone line.

[0027] Further, it is possible to solve the problem that the amount of information is limited or the information is old as in the case where only the information stored in the memory medium is fetched.

[0028]

As described above, the navigation apparatus of the present invention transmits specific information including its position information and unique information from a transmitting station by radio, and transmits the transmitted specific information to a navigation apparatus mounted on a vehicle. And the arithmetic processing means displays the position of the transmitting station on the map displayed on the display means using the received specific information.

Thus, the location of the store can be transmitted by radio waves, and can be automatically received and displayed on the display means.
