DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle navigation device, and more particularly, to an on-vehicle navigation device for acquiring information on a point on a road map in advance and superimposing and displaying the information on the road map.

[0002]

2. Description of the Related Art A conventional on-vehicle navigation device reads map information of its own traveling area from a map database stored in a CD-ROM or the like via a recording medium reading device, and reads a main controller and a graphic controller of the on-vehicle navigation device. Is configured to display a map based on map information and the like on the display device and its own position on the display map under the control of the user.

Further, in a vehicle-mounted navigation device, a destination is set from a current location (or a departure location), so that a route search function for searching for a route from the departure location to the destination, and further a route determined by the route search function are performed. Therefore, a route guidance function for guiding a route to a destination is provided.

As shown in FIG. 3, a portable terminal 1 is connected to a vehicle-mounted navigation device 1 via a portable terminal connection device 12.
3 connected to the Internet, and obtains information from the information provider 4 by connecting to the Internet, such as an arbitrary point selected on the map display screen of the on-vehicle navigation device 1 and stores around the route obtained by the route search function. can do.

[0005]

However, in the above-described conventional system in which information about a desired point and a route is acquired from an information provider using a portable terminal device and a portable terminal from an on-vehicle navigation device, the above-mentioned conventional system is used. There is a problem that a mobile terminal and a mobile terminal connection device are required in addition to the navigation device.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an on-vehicle navigation device which does not require a portable terminal and a portable terminal connection device, and reduces the operation in a vehicle.

[0007]

According to the present invention, there is provided an in-vehicle navigation device comprising:
P which stores information of a predetermined point on the map in advance
The C memory card is inserted into a PC card slot of the in-vehicle navigation device, and the information of the predetermined point is superimposed and displayed on a map on a display screen of the in-vehicle navigation device.

According to the on-vehicle navigation device of the present invention, a PC memory card in which information of a predetermined point on a map is stored in advance in a PC card slot of the on-vehicle navigation device, Is superimposed and displayed on the map on the display screen. Therefore, the information of the predetermined point can be superimposed and displayed on the map on the display screen without having the portable terminal connection device and the portable terminal, and the portable terminal connection device and the portable terminal become unnecessary. .

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an on-vehicle navigation device according to the present invention will be described with reference to embodiments.

FIG. 1 is a diagram illustrating the configuration of an on-vehicle navigation device according to an embodiment of the present invention.

In the on-vehicle navigation device 1 according to one embodiment of the present invention, information on a predetermined point on a map is stored in the PC memory card 3 in advance by a method described later. The PC memory card 3 storing the above information is inserted into the PC card slot of the in-vehicle navigation device 1, and the information of the predetermined point is displayed in a superimposed manner on a map on the display screen of the in-vehicle navigation device 1. .

Therefore, the information of the predetermined point is superimposed and displayed on the map on the display screen of the on-vehicle navigation device 1 without having the portable terminal connection device and the portable terminal. The memory element of the PC memory card 3 is formed of, for example, an EEPROM.

Next, storage of information in the PC memory card 3 inserted in the on-vehicle navigation device 1 will be described.

The browser on the personal computer 2 searches the MAP server home page via the Internet. The home page of the MAP server is displayed on the display screen 5 in FIG.
Drawing of a map and scrolling of a map according to an instruction to the display 7, registration of a point according to an instruction to the display 71, and display 7
2, a route search can be performed by an instruction to the display 73.

The user accesses the home page of the MAP server from the personal computer 2 via the information supply source 4, and draws a desired map on the display screen by instructing the display 7, display 71, display 72, and display 73, and scrolls. Perform location registration, location search, route search, and display 7
4, the information is downloaded to the PC memory card 3 and information on a predetermined point on the map is stored.

The setting of a predetermined point on the map is as follows:
One or more can be selected from the map on the display screen 5, the user's registered point, the point search, the route search, and the like. The information at the point set in this way includes, for example, the name of the store at the point, the items handled by the store, parking lot information, parking fee,
As with other information, the information type can also be selected.

When information on the periphery of the route is obtained as a result of the search, a point is set for each fixed distance on the route,
The information around the point is acquired. Further, the fixed distance on the route can be changed.

By inserting a PC memory card 3 preliminarily storing such information into a PC card slot of the in-vehicle navigation device 1, the in-vehicle navigation device 1
, And the map and the information stored in the PC memory card 3 for the corresponding point on the map are superimposed and displayed on the display screen of the vehicle-mounted navigation device 1.

A personal computer 2 reads a CD-ROM used by the in-vehicle navigation device 1 and uses an application program for drawing a map, scrolling, registering a point, and searching for a route to obtain information on a point selected by the user and around the route. Can be obtained from the information supplier 4 by using the Internet. The information thus obtained is stored in the PC memory card 3 in advance. The PC memory card 3 storing the information is inserted into the PC slot of the in-vehicle navigation device 1 and read by the in-vehicle navigation device 1, and stored in the PC memory card 3 for a map and a corresponding point on the map. The displayed information may be superimposed and displayed on the display screen of the vehicle-mounted navigation device 1.

[0020]

As described above, according to the in-vehicle navigation device according to the present invention, information of a predetermined point on a map is stored in a PC memory card in advance, and is inserted into a PC card slot of the in-vehicle navigation device. Since the information on the predetermined point is superimposed and displayed on the map on the display screen of the on-vehicle navigation device, the operation in the vehicle is reduced, and a portable terminal or the like is not required. There is also an effect that can be done.
