The navigation device 1 is mounted on an automobile and displays a current position and a route guide to a destination, which is useful for determining a course of a driver.

Therefore, roughly, in the navigation device 1, the central processing unit 3 realized by a microcomputer or the like responds to an input operation to the operation key 2 by using the CD-ROM device 5 via the communication bus 4. To read map data of a desired area. In response to the instruction, the processing circuit 6 controls the CD-ROM
The map data of the corresponding area is read from the map data recorded on the disk 8. Thus, corresponding to the map data input from the processing circuit 6 via the communication bus 4,
The central processing unit 3 drives the display device 10 realized by a liquid crystal display device or the like via the display drive circuit 9 to realize the map screen display of the desired area.

Latitude, longitude, altitude, running speed, and the like are calculated, and the calculation results are output to the central processing unit 3 via the communication bus 4.

The navigation device 1 further includes a geomagnetic sensor 13, a gyro sensor 14, and a wheel speed sensor 15. The geomagnetic sensor 13 detects the traveling direction of the vehicle, the gyro sensor 14 detects a change in the attitude of the vehicle, and the wheel speed sensor 15 detects the vehicle speed. The detection results of the sensors 13 and 14 are converted into digital values by analog / digital converters 16 and 17, respectively, and input to the processing circuit 19. Also, a wheel speed sensor 1
The vehicle speed pulse from 5 is counted by the pulse counter 18 and input to the processing circuit 18. At this time, when the reverse position detector 25 detects that the gear position of the transmission is at the reverse position, the count value is set to a negative value.

The processing circuit 19 receives data relating to the position of the vehicle and the like input from the processing circuit 3 using the operation keys 2, whereby the processing circuit 19
The current vehicle position is estimated and calculated from the detection results of 3 to 15, and the calculation result is output to the central processing unit 3. In this way, the vehicle position can be accurately measured by the so-called dead reckoning even at a point where the GPS receiver 11 cannot accurately measure the vehicle position, for example, in the shadow of a building, under an overpass, or in a tunnel.

FIG. 6 is a flowchart for explaining the display operation as described above. In step n1, it is determined whether or not the measurement data such as the vehicle position, the traveling direction, and the traveling speed have been updated, that is, whether or not the time T1 has elapsed, and if so, step n2
Move to a.

In step n2a, it is determined whether or not the map data needs to be updated, that is, whether or not the measured vehicle position exists in the currently displayed map screen. That is, in the decoder 7 from the CD-ROM disk 8, data of an area which is larger than the area actually displayed, for example, about four times as large, is read and stored in the memory. When the vehicle position comes out of the area of the data, the map data corresponding to the measured vehicle position is read from the CD-ROM device 5 in step n2b, and the drawing process of the data is performed in step n2c. The process proceeds to n2d, otherwise directly goes to step n2d. In step n2d,
The display start address of the map screen is calculated. The display start address is used to define an area of the map screen to be displayed. Of the stored data, the area corresponding to the left corner of the area to be displayed is stored. The displayed memory area is calculated as the display start address. Therefore, when the display screen is scrolled as the vehicle travels, the display start address is changed.

If there is no change in the measured data in step n1, the process proceeds to step n3, and it is determined whether or not the time T2 has elapsed. If not, the process returns to step n1, and if so, the process proceeds to step n4. Further, the process also proceeds from step n2d to step n4, and thus the processes after step n4 are performed only four times per second.

At step n4, a flag PTN indicating which of the two patterns A or B should be selected.
Is set to 1 or not. If it is set, it is reset to 0 in step n5, and then goes to step n7. If it is reset, it is set to 1 in step n6 and goes to step n7. . When the flag PTN is set to 1, pattern A is selected, and when the flag PTN is reset to 0, pattern B is selected. Therefore, switching between patterns A and B is performed only four times per second.

In step n7, when the azimuth of the azimuth is set to 0 degree, the calculation as to which of the azimuth region numbers shown in FIG. 3 corresponds to the measured relative direction θ of the vehicle is performed according to the following equation. Orientation area number = {(θ + 22.5) / 8} −1

In step n8, the type of pattern A or B set in step n5 or step n6,
A corresponding pattern number is read from the azimuth area number obtained in step n7 based on Table 1 above, and a drawing process of a symbol mark as shown in FIG. 4 is performed.
In step n9, a composite image of the images rendered in steps n2c and n8 is displayed, and the operation ends.

As described above, by switching and displaying the symbol marks representing the vehicle position and the traveling direction in accordance with the elapse of the time T2 or in response to the input operation or the change in the traveling direction, a display having an animation operation is provided. Can be performed, the user can be kept fresh and interested, and a display that does not get tired can be performed.

Thus, in the present invention, a plurality of symbol marks indicating the current position are prepared, and the symbol mark is selected and displayed as the current position advances. A plurality of symbol marks may be prepared in one direction and selected as they progress, or two types of symbol marks may be alternately selected in one direction as the current position progresses. .
Further, a plurality of symbol marks are prepared according to the traveling direction, a symbol mark is selected based on the traveling direction, and the traveling direction is further divided into a plurality of predetermined regions, and it is determined which region corresponds to the symbol direction. The determined symbol mark for each area may be displayed, and a plurality of symbol marks may be associated with each area.

FIG. 7 is a flow chart for explaining a display operation according to another embodiment of the present invention. Similar to FIG. 6, the same reference numerals are given to the corresponding parts. It should be noted that, in this embodiment, the symbol mark is also changed corresponding to the running speed Vs.

That is, when the azimuth region number of the traveling direction is obtained in step n7, the process proceeds to step n21, where the traveling speed Vs is equal to or higher than 0 km / h and is less than a predetermined threshold speed V1, for example, less than 10 km / h. It is determined whether or not there is, and if so, at step n22, the speed flag SP is set to 0. Step n2
If the running speed Vs is equal to or higher than the threshold speed V1 in step 1, the process proceeds to step n23, and it is determined whether the speed is lower than a predetermined threshold speed V2, for example, less than 80 km / h. Is set to 1, otherwise the speed flag SP is set to 2 at step n25.

Different symbol marks are set corresponding to the speed flag SP, the pattern, and the azimuth area number as shown in Table 4, and after the corresponding symbol mark is drawn in step n8a. , Said step n9
Move on to Therefore, for example, under the conditions shown in Table 5, the symbol mark is selected as shown in Table 6.

[Table 5]

[0046]

[Table 6]

By changing the symbol mark in accordance with the traveling speed Vs in this way, for example, when the speed is equal to or higher than the threshold speed V2, a symbol mark indicating danger may be displayed to improve safety.

FIG. 8 is a flow chart for explaining a display operation according to still another embodiment of the present invention, which is similar to the above-described embodiment, and corresponding portions are denoted by the same reference numerals. In this embodiment, the time T2 is changed for each speed area divided by the threshold speeds V1 and V2.

That is, when the traveling speed Vs is equal to or more than 0 km / h and less than V1 in step n21, the process proceeds to step n22a, where the time T2 is set to 0.5 seconds, whereas the traveling speed V3 is decreased in step n23. V1
If it is less than V2, the time T2 is set to 0.25 seconds in step n24a, and if not, 0.1 seconds is set to the time T2 in step n25a.

Therefore, when the conditions are as shown in Table 7, the displayed symbol marks are as shown in Table 8, that is, as shown in FIG. The traveling speed can also be expressed by changing the switching interval of the symbol mark corresponding to the traveling speed Vs in this manner.

According to the speed, a symbol mark indicating danger can be selected and displayed.

FIG. 10 is a flowchart for explaining the display operation of another embodiment of the present invention, which is similar to the above-described embodiment, and the corresponding parts are denoted by the same reference numerals. In this embodiment, in step n21, the traveling speed Vs
When the vehicle at or below the threshold speed V1 is almost stopped, the process proceeds to step n41, where a counter for measuring the duration of the stopped state is set. As shown in Table 9 and FIG. Similarly to the above, two patterns of SA or SB are set for each count value C.

[0055]

[Table 9]

That is, when the traveling speed Vs is not lower than the threshold speed V1 in step n21, after the count value C is reset to 0 in step n41,
At step n8, the symbol processing shown in FIG. 4 is selected in accordance with the display area number and the flag PTN, and the drawing process is performed.

On the other hand, when the traveling speed Vs is lower than the threshold speed V1, the process proceeds to step n42, and the flag PTN switched at step n5 or n6 is set to 1
It is determined whether or not is set to, and only when it is, that is, every 0.5 seconds, the process proceeds to step n43,
The count value C is updated by being incremented by one. In step n44, it is determined whether or not the count value C has exceeded the maximum value CMAX, that is, 7 from Table 9 and FIG. 11, and if so, in step n45 the count value C is set to the maximum value CMAX. The process proceeds to n8b, otherwise directly goes to step n8b.
In step n8b, corresponding to step n8, the symbol mark shown in FIG. 11 is selected from the count value C and the flag PTN, and a drawing process is performed.

As described above, by switching the symbol marks even when the vehicle is almost stopped, it is possible to help the user to be irritated even during a traffic jam.

As another embodiment of the present invention, as shown in FIG. 12, a pattern C or D is created as shown in Table 10 using a cat of a character completely different from the character shown in FIG. In advance, these patterns A or B or SA or SB and C
Alternatively, D and D may be arbitrarily selectable.

[0060]

[Table 10]

That is, when an input operation from the operation key 2 is performed, an interrupt operation of key input processing as shown in FIG. 13 is started, and it is determined in step m1 whether the input operation is a character change request. If not, the other processing corresponding to the key operation is performed in step m2, and the process returns to the main routine as shown in FIG. 14 described later.

On the other hand, if it is a character change request in step m1, the process proceeds to step m3, where it is determined whether or not the currently selected character is the pattern SA or SB. To switch to the pattern C or D, otherwise to step m5 after switching to the pattern SA or SB in step m5.

In the operation shown in FIG. 14, similarly to the operation shown in FIG. 6, when the azimuth area number is obtained in step n7, the process proceeds to step n51 to determine whether the selected character is pattern SA or SB. Is determined,
If so, the process proceeds to step n8d to selectively display the symbol marks shown in Table 9 and FIG.
Otherwise, the process moves to step n8c, and the pattern C or D shown in Table 10 and FIG. 12 is selectively displayed.

As described above, by making the character itself changeable, a display desired by the user can be further performed. Further, the character may be arbitrarily created by a user.
