Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle navigation system.

[0002]

2. Description of the Related Art A conventional navigation device is a device that allows a driver to easily reach a destination by using this information by indicating the position and name of the destination on a map.

[0003]

By the way, in the conventional navigation device, although the location of the destination can be known, the business situation of the location is unknown, so that even if the destination arrives at the destination, it is closed. There was a problem that I had to find another place again. Especially in the drive at midnight, it was very difficult to find a destination that was open.

[0004] Therefore, an object of the present invention is to provide a vehicle navigation device which can know business information of the day while driving.

[0005]

In order to achieve the above object, a vehicle navigation apparatus according to the present invention, as shown in FIG. 1, is an information transmitting side apparatus 1 for transmitting incidental data regarding points on a map, In a vehicle navigation device comprising a vehicle side device 2 having a function of receiving transmission data from the information transmitting side device 1, the vehicle side device 2 holds map information holding means 3 for holding map information,
A current position detecting means 4 for detecting the current position of the vehicle; a peripheral map information extracting means 5 for extracting map information around the current position detected by the means 4 from the map information holding means 3;
Map data display control means 7 for displaying the map information extracted by the means 5 on the display portion 6 and displaying the current position detected by the current position detecting means 4 on the displayed map, and the information transmitting side means. A receiving unit 8 for receiving the transmission data from 1, and an operating unit 9 for issuing an operation signal for displaying incidental data regarding each point on the map,
And an accessory data display control means 10 for displaying the accessory data of each point on the map received by the receiver 8 on the display unit 6 in response to an operation signal from the operation unit 9. ..

As the above-mentioned supplementary data, for example, sales information about each point can be considered. In that case, it will be easier to understand if an identification mark is added to each point on the map according to whether it is in business or not, and if it is displayed in different colors, it will be easier to understand.

Further, the information transmitting side device can be composed of an input section for inputting arbitrary data and a transmitting section for transmitting the input data as a radio signal, and particularly as a receiving section, Street beacons can be used.

[0008]

In the present invention, by operating the operation unit, incidental data such as sales information about each point on the map is displayed on the display unit. Therefore, while driving, it is possible to immediately understand where business is in business and easily reach the point during business.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of a navigation device according to the present invention. (A) shows the configuration of the information transmission side device 1. The information transmitting side device 1 includes an input unit 11 for inputting arbitrary data, a transmitter 12 for transmitting the input data as a radio signal, and a transmitting antenna 13. In this case, the input data is transmitted to each vehicle from the road beacon via the relay station. The input data is incidental data such as business information about each point on the map, and useful information for the driver such as business status, business hours, price, and other service information on the day can be given.

Further, (b) shows the structure of the vehicle side device 2. The vehicle-side device 2 has a data processing control unit 15 composed of a microcomputer. This data processing control unit 1
Signals from detectors necessary for knowing the current position of the azimuth meter 16, the distance meter 17 and the like are input to 5, and the data processing control unit 15 determines the current position of the vehicle based on these input signals. calculate.

Further, the data processing controller 15 is a CD-R.
It is connected to the OM driver 18 and drives and controls the driver 18 to read the map information stored and held in the CD-ROM 19 (map information holding means). Then, a map around the calculated current position is selected, and the image output unit 2
A display control signal is sent to 0 to display a map around the current position on the display unit 6 and display the current position on the map.

Further, the data processing control section 15 is supplied with transmission data from the information transmitting side apparatus 1 via the beacon antenna 21 and the beacon receiver 22. This data is processed into a shape desired by the operator according to the operation of the operation unit 23 and is displayed on the display unit 6.

The vehicle-side device 2 has its constituent elements shown in FIG.
It is deployed as shown in. Operation unit 23, display unit 6,
The CD-ROM driver 18 is provided in the vicinity of the driver's seat, and the other elements are provided so as not to get in the way at their optimum positions.

Next, the operation of this embodiment having the above structure will be described. In the following, a sales service information providing system for a gas station will be described as an example.

First, as a procedure on the transmitting side, at each gas station, as shown in FIG. 4, first, the gas station code number, the business situation on the day, the business hours, the manufacturer name,
Information such as gasoline price is input (step 101).
This is then transmitted from the transmitter to the relay station (step 1
02, 103), and the above-mentioned input data is transmitted from each road beacon from here (step 104).

Next, when the driver needs to search for a gas station, he first performs a search start operation (step 201). Next, C for gas station
The D-ROM is set (step 202). Then
The current position is calculated and read based on the signals from the azimuth meter, the distance meter, and the road beacon (step 203), and this is processed by the control unit to obtain the map information around the current position on the CD-RO.
Read from M (step 204). Further, the business service information of the gas station around the current location transmitted from the road beacon is read (step 205), and then it is checked whether the map information and the code number of the gas station match (step 206). If they do not match, steps 203 to 206 are repeated until they match.

If they match, it is discriminated whether the gas station on the map is open or not, and the gas station on the map is color-coded (step 207). For example, blue if it's open,
If it is not open, it is colored red. Next, it is checked whether there is a gas station in operation (step 208). If there is no gas station in operation, the driver displays a wide area map of the gas station by operating the operation unit (step 209), and the gas station Move to the direction where there are many (step 210) and step 20
Repeat steps 3 to 210.

If there is a gas station in operation, the service information such as business hours, manufacturer name, and gasoline price of each gas station is displayed by operating the operation unit (step 211). A gas station is selected (step 212), the target gas station is moved to (step 213), and the search operation is ended (214).

As described above, since the business information of the gas station can be known in advance, it is possible to immediately find out the gas station that is operating and reach there.

Although the above example shows the case of providing service information at a gas station, the present invention can also be used in other information providing systems such as entertainment facilities such as movie theaters and bowling alleys, or convenience stores. It is possible to

[0021]

According to the present invention, since it is possible to know the business information of each point in advance, it is possible to avoid going to a destination that is closed. Also, if you drive late at night, it will be easier to find a destination that is open for business. Further, by comparing the sales information of each point, the driver can select the most suitable destination at that time.
