Map Calling Method of Vehicle Navigation System

The present invention relates to a method of calling a map of a vehicle navigation apparatus, and in detail, a vehicle navigation apparatus capable of confirming a residence location of a relevant person by calling a name, phone number, address, and map of a place of residence using only the resident registration number of a specific person through a resident registration number search. It relates to a method of calling a map.

In recent years, the increasing number of vehicles on the road has caused very large traffic congestion. In large cities, traffic congestion is more serious, but a lot of resources are required to expand the road network due to rising land prices.

Therefore, as a more practical solution, attempts have been made to use the existing road network as it is but to efficiently control traffic flow using an artificial intelligence system. Thus, as one way, a car navigation system is being developed.

The most basic function of the vehicle navigation system is to track the location of the vehicle in operation and display it on the road map accurately.The additional function is to provide useful information about traffic conditions, gas stations, and government offices on other roads. .

Such a vehicle navigation system employs a plurality of sensors and uses the information provided therefrom to track a vehicle location using a stand-alone navigation system and a navigational navigation system using location information provided by a GPS satellite. Devices and hybrid navigation systems combining these two devices, and the vehicle navigation systems described below represent all cases of the above-described navigation devices.

In general, the vehicle navigation apparatus receives the location information from the Global Positioning Satellite (GPS) satellite using the Global Positioning Satellite Antenna and maps the received location information data to the map data recorded on the compact disc. It is a device that shows the current location on the screen by performing map matching.

Movement of the host vehicle and the main controller 7 for matching the current position of the host vehicle on the map data stored in the CD-ROM 6 using the control unit 5, the longitude and latitude data processed by the receiver 3. The indicator 8 displays the indicator 8 for visually displaying the route and map, the indicator controller 9 for controlling the driving of the indicator 8, and the map data of the current vehicle position. Temporarily to show on It has a temporary data storage unit 10 for storing.

In the above-described configuration, the map data stored in the CD-ROM 6 is based on topographical maps of predetermined scale ratios created on the basis of aerial photographs, and geographical information on road driving and road management is digitized. Such map data is stored by adding attribute data based on the map data of the basic road. The attribute data includes information on intersections, and the intersections appearing during road driving are classified by the intersection name for determining the intersection and the main buildings of the intersection.

First, the user inputs search information to be found through the input unit 4 (S10). The search information entered at this time is mainly the names or names of public institutions or major facilities.

When the search information is input through the input unit 4, the main control unit 7 searches the input search information in the database recorded in the CD-ROM 6 (S20).

After the search, the main controller 7 determines whether the search information input through the input unit 4 exists in the database of the CD-ROM 6 (S30).

If it is determined in S30 that the search information input through the input unit 4 does not exist in the database of the CD-ROM 6, the main controller 7 determines that there is no related information with respect to the information desired by the driver and the display controller 9 ) Is displayed on the display 8 to inform the driver (S31).

However, if it is determined in S30 that the search information input through the input unit 4 exists in the database of the CD-ROM 6, the main controller 7 drives the CD-control unit 5 to be input by the driver from the CD-ROM 6. Road map data corresponding to the search information is acquired (S40).

After the road map is acquired, the main controller 7 performs driving guidance (S50). The main controller 7 performs the following process to guide the driving.

The main controller 7 searches for a route on which the host vehicle is currently traveling. After searching for the route on which the own vehicle is traveling, the main controller 7 acquires road map information including the route currently running from the CD-ROM 6.

The main controller 7 acquires the road map information from the CD-ROM 6 and causes the indicator controller 9 to display the road map on the indicator 8. When the display controller 9 displays the road map on the display 8, the main controller 7 stores the road map data in the temporary data storage 10 of the display controller 9 (S40).

However, in the past, when searching the route by inputting search information, the search was performed only by the names of public institutions and well-known buildings. Thus, when visiting a specific person's place of residence, it was impossible to call the map of the place of residence only by the name of the specific person.

The present invention provides a map calling method of a vehicle navigation apparatus that can determine the residence location of the person by calling the name, phone number and address and the map of the place of residence with only the resident registration number of the person through the resident registration number search to solve the above problems. The purpose is to.
