4A and 4B show a case where a map near the desired point is displayed on the display unit by scrolling. When the screen of the display unit 11 is a touch panel as shown in FIG. Display the map near the desired point by scrolling the map up, down, left, or right to the desired point by touching the scroll operation part at the top center, bottom center, left center, or right center 11 is displayed. FIG. 4B shows a case where the remote controller 12 is used for scrolling. By operating the four-way key 12a of the remote controller 12, the screen map on the display unit 11 is scrolled up, down, left or right to a desired point. And display the map near the desired point on the display unit 11.
[0005]
FIGS. 5A and 5B show a case where a map near a desired point is displayed on the display unit by selection from the registered point list. The pre-registered registered point list shown in FIG. 5A is displayed on the screen of the display unit. After reading, the desired point is selected by placing the cursor (■) on the mark of the desired point or the name of the desired point using the remote controller 12 in FIG. 5B, and a map of the desired point is displayed on the display unit. Let
[0006]
[Problems to be solved by the invention]
However, in the method of scrolling the map to the vicinity of the desired point, it is necessary to watch the map while scrolling the map, and the operation becomes complicated. Also, the method of selecting from the registered spot list is complicated.
[0007]
The present invention has been made in view of the above points, and an object of the present invention is to provide a navigation device that can display a map near a desired point on the display unit with a single touch and can be easily operated.
[0008]

Desired point registration means for registering position information of a desired point, and for a desired point display formed by a touch panel on a part of the screen of the display unit in a guidance mode in which a map for guiding the course of the vehicle is displayed on the display unit A map near the desired point registered based on the position information of the desired point registered by the desired point registration means when the desired point display operation unit is operated in the guidance mode. and displays on the display unit is read from the map information storage unit, and displaying the VICS information received by the VICS receiving unit to the display unit.
[0009]
The second navigation device of the present invention includes a map information storage unit that stores a map of each place, a road name, etc., a VICS reception unit that receives VICS information, a map read from the map information storage unit, and the VICS comprising a display unit for displaying the VICS information received by the receiving unit, and a desired place registration means for registering the position information of the desired point, and a key for the desired point display provided on the remote control to operate the device, the route of the vehicle When the desired point display key is operated in the guidance mode in which the map for guiding the user is displayed on the display unit, the desired point vicinity registered based on the position information of the desired point registered by the desired point registration means and displays on the display section of a map read from the map information storage unit, and the display means displays the VICS information received by the VICS receiving unit to the display unit That.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a navigation device according to the present invention will now be described in detail with reference to the accompanying drawings. FIG. 2 is a block diagram showing an embodiment of the navigation apparatus of the present invention. The navigation device includes a measurement unit 21, a control unit 22, an operation unit 23, a display unit 24, a map information storage unit 25, a VICS reception unit 26, a remote control 27, and a remote control reception unit 28. It is mounted on a vehicle not shown.
[0012]
The measurement unit 21 includes a GPS receiver, a gyroscope, and the like, and repeatedly measures the current position of the vehicle on which the navigation device is mounted, for example, once per second. The control unit 22 includes a CPU and the like, and controls the entire navigation device. The operation unit 23 includes a touch panel provided on the screen of the display unit 24 and mechanical keys provided on the surface of the casing around the display unit 24. The operation mode of the navigation device, the departure point of the vehicle, the purpose Enter various information such as location. The remote controller 27 inputs an operation mode of the navigation device by hand operation instead of the operation unit 23. For example, a signal is transmitted from the remote controller 27 by infrared rays, and this signal is received by the remote controller receiver 28 and supplied to the controller 22.
[0013]
The map information storage unit 25 has a CD-ROM or DVD-ROM, and stores maps, road names, and the like in various locations. The display unit 24 includes a color LCD display, and displays various information such as a menu, a 50 sound input screen, or a map read from the map information storage unit 25. The VICS receiving unit 26 receives VICS information such as FM multiplex broadcast in order to display the VICS information on the map displayed on the display unit 24, for example.
[0014]
In the above navigation apparatus, the screen of the display unit 24 is a touch panel as the operation unit 23 as described above, but a part of this touch panel is a desired point display operation unit 23a as shown in FIG. . Then, after registering a desired point in advance in the desired point registration mode, if the desired point display operation unit 23a is operated in the guidance mode (when the desired point display operation unit 23a is touched), the memory in the control unit 22 is stored. A map near the desired point registered based on the registered desired point is read from the map information storage unit 25 and displayed on the display unit 24 so that the desired point is at the center of the screen.
Here, the display range is a range that can be displayed on the display unit 24 with respect to a predetermined scale map centered on a desired point.
[0015]
Thus, in the above navigation device, a map near a desired point can be displayed on the display unit 24 with a single touch by simply touching the desired point display operation unit 23a on the touch panel of the display unit 24. Therefore, it is possible to display the map near the desired point on the display unit 24 by performing the operation. For this reason, for example, if a frequently congested location is registered as a desired location, a map near the location is displayed on the display unit 24 with one touch, and the VICS information received by the VICS receiving unit 26 is simultaneously superimposed on the map. You can see traffic information near the desired location, which is very convenient for driving.
[0016]
The desired point is registered by, for example, displaying a 50-sound input screen on the display unit 24 in the desired-spot registration mode, and then picking up “Hiragana” one by one on the 50-sound input screen and inputting the place name. Can do. In this case, the range of the desired point is narrowed and the display map becomes more detailed as the place name to be input is input to the town name and address in detail. In addition, a desired point can be registered by attaching a mark such as Δ or ◯ to a predetermined position in the map displayed on the display unit 24. In this case, the desired point is directly and uniquely designated. Furthermore, the desired point can be registered by various other methods. Information on the desired point registered in this way is stored in a memory in the control unit 22. The registration of the desired point can be changed by resetting the registration.
[0017]
FIG. 3 is a diagram for explaining another embodiment of the present invention and is a diagram showing a remote controller 27. In another embodiment, the remote control 27 is provided with a desired point display key 27a. Then, by operating the desired point display key 27a, a pre-registered map around the desired point is read out from the map information storage unit 25 and displayed on the display unit 24.
[0018]
