Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a driving information display device that displays map information of a vehicle.

(b) Prior Art In recent years, standards and developments have been made for vehicle running devices that guide vehicles to a desired location. According to such a device, a map of the driving area, the route to the destination position, and the driving position of the vehicle are displayed on the CRT display installed in the car, so the driver can view the screen of the CRT display. By referring to this, you can quickly reach the target position. In such a device, map information is stored on a compact disk for each region, and when displaying a map, map information for a designated region is read out from the disk, reproduced, and depicted on the CRT screen.

In addition, the route to the destination position is achieved by inputting the vehicle's current position and destination position on a map drawn on the CRT screen by moving a cursor. Among the roads connecting the locations, the shortest one is selected and displayed by, for example, changing its color. The traveling position of the vehicle during vehicle guidance is determined by adding the traveling direction and traveling distance to the current position input by moving the cursor using a direction sensor that detects the traveling direction of the vehicle and a distance sensor that detects the traveling distance of the vehicle. This is determined by updating the vehicle's current position from time to time.

In such a vehicle traveling device, the map information of the predetermined information is read from the disk as described above, but there are times when it is desired to add information that serves as a landmark for the driver to the map information. be.

The name, etc. of the location can be entered using the .

(c) Problems to be Solved by the Invention However, the above-mentioned prior art has a problem in that it requires complicated operations such as moving the marker and operating the Japanese syllabary key when entering landmark information. Drivers often request the input of landmark information when they find the landmark information while driving the vehicle, but if such a complicated operation is required, the landmark information cannot be input at that moment. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a driving information display device that allows input of landmark information even when the vehicle is traveling.

(d) Means for Solving the Problems In view of the above problems, the present invention provides a reproducing means for reading and reproducing map information from a storage medium, a current position detecting means for detecting the current position of the vehicle, and a combination of the reproducing means and the current position. A driving information display device comprising a map and a display means for displaying the current position of the vehicle on a screen based on information from the detection means,
auxiliary storage means for storing position information of the vehicle and attributes of the point; and position input for inputting position information of the point into the auxiliary storage means based on information from the current position detection means through operations when the vehicle is running. and attribute input means for inputting the attribute of the input point by an operation after the input.

(e) Operation When the position input means is operated at a desired timing while the vehicle is running, the position of the vehicle at the time of operation is input into the auxiliary storage means based on the information from the current position detection means. Further, after this input, by operating the attribute input means, the attribute of the position corresponding to the input position is input into the auxiliary storage means.

(f) Example Hereinafter, one embodiment of the present invention will be described using the drawings.

FIG. 1 is a circuit block diagram of the same embodiment.

(1
), an input circuit that inputs input to the auxiliary storage circuit (5) via (
7) is a ROM that stores an operating program for the microcomputer (1) and attribute information to be described later.

FIG. 2 is a diagram showing, for example, a key operation section of an input circuit disposed on the front surface of the apparatus main body. As shown in the diagram, the key operation section (
8) is provided with two function keys (9a) (9b) and numeric keys (10) from 1 to 9. Here, when the registration key (9a) among the function keys is pressed, the attribute information shown in FIG. 3(a) is displayed, and when the display key (9b) is pressed, the attribute information shown in FIG. 3(b) is displayed. ) is displayed on the screen via the display circuit (4).

Next, the operation of this embodiment will be explained based on the flowcharts of FIGS. 4 and 5.

FIG. 4 is a flowchart that defines writing of landmark information. For example, suppose that the vehicle is traveling and approaches a "bookstore". At this time, in order to write this "bookstore" information on the map, the driver may first press the registration key (9a) described above. When it is determined in step 1 that the registration key (9a) is pressed, in step 2 the current position detection circuit (2
), the registration key (

The registration menu shown in FIG. 3(a) is displayed on the screen 4). The driver looks at this screen and selects the number with the corresponding mark (i.e. "3" for "bookstore") using the numeric keys (
1), the name (attribute information) of the landmark is stored in the auxiliary storage circuit (5) (step 5).

Therefore, by the above operation, the position and name (attribute) of the landmark are stored in the auxiliary storage circuit (5).

FIG. 5 is a flowchart defining readout of landmarks. When reading a mark, first the display key (9b) is pressed. In step 1, it is determined whether or not this display key (9b) has been pressed, and if YES, the screen shown in FIG. 3(b)
The display menu shown in is displayed on the screen of the display circuit (4) (step 2). Next, the driver inputs the number assigned to the required attribute (for example, "3" for "bookstore") from the display menu displayed on the screen using the numerical keys (10). Accordingly, in step 3 this number is changed to the input circuit (
6) to the microcomputer (1), and in step 4, the position having the attribute corresponding to that number is input to the auxiliary memory circuit (

In FIG. 6, landmarks having the attribute "bookstore" are designated and displayed on the map. Here, “bookstore”
In the above method, the running position l of the vehicle is stored as the position of the vehicle, but when it is displayed, it is displayed as a collection of points in a circle with a radius r and the middle CI is the running position P, as shown in Fig. 7. ing.

As described above, this embodiment uses the running position of the vehicle, and when the vehicle approaches a landmark position while driving, the position of the landmark can be determined simply by pressing the registration key. Since it can be input as the driving position of the vehicle, the position information of the landmark can be input with a simple operation without the need for complicated work such as moving a marker or the like. Furthermore, the attribute of the landmark can be input by pressing the number key once, so the input operation of landmark information can be significantly simplified as a whole.

Note that the present invention is not limited to the above embodiments, and various other changes are possible. For example, although the attribute of the landmark to be displayed is input using the operation keys when displaying the map, it is possible to simultaneously read out the landmark information when displaying a predetermined map, and all of the information read from the auxiliary memory circuit can be read out without specifying the attribute separately. Landmarks may be displayed superimposed on this map.

(G) Effects of the Invention As described above, according to the invention, landmark information can be stored with an extremely simple operation, and thus landmark information can be stored instantly even while driving.
