As shown in Japanese Patent Application Laid-open No. 48-48-48108, etc., a magnetic tape has a pre-written guidance recorded in advance, and by generating it internally, it is possible to follow the backdoor guide [:I$ It's like driving a JJ car.

(3) As shown in Japanese Unexamined Patent Publication No. 46-6066, guidance is recorded by driving a magnetic tape intermittently every specific distance traveled by a car, for example, every 2 km, and the same guidance is recorded the next time the car travels on that road. Special wk? The magnetic tape is played back every distance T and guidance is uttered.

However, although the route guide device for a car measures the distance traveled and provides guidance according to the distance traveled, a certain amount of error occurs in measuring the distance traveled.

Even if the errors in measuring the distance traveled are not that large, they can accumulate over long distances and become large enough to cause the guidance to become inconsistent. However, the conventional route guidance device described above does not have an error correction function, and correction thereof is extremely troublesome.

[Purpose of the invention]

The dart circuits G2+G3 are controlled by a signal from the CPU 22. Further, the counter 31 is controlled by a preset signal and a reset signal from the CPU 22. The pulse generating circuit generates a pulse every time the car travels a certain distance, and the output pulse is sent to the counter 3 as well as the CPU 2.
Sent to 2.

Next, the operation of the above embodiment will be explained. First, the operation for recording route guidance information on a magnetic tape will be explained according to the flowchart of FIG. When creating a guidance stage, an ordinary music tape is set on the tape recorder 25 and the recording key 2 is operated. By operating this recording key 2, the recording flow shown in FIG. 5 starts. That is, when the recording key 2 is operated, the CP
U22 connects to tape recorder 2 via interface 23.
A recording mode signal and a start command are sent to the controller 5, and the magnetic chip f is moved as shown in step ^l of FIG.

Next, the process proceeds to test step A2, where a start code STC is written on the magnetic tape as shown in the tape format of FIG. When the writing of the start code STC is completed, the running of the tape is stopped as shown in step 7fA3, and the process proceeds to step 7fA4, where it is in the bold (HALT) state until the microphone switch 268 is turned on. When the microphone switch 26S is turned on in this state, the tape starts as shown in step A5, and the running state of the tape is maintained as shown in step A6 until the microphone switch 26S is turned off. Record guidance. For example, [This tape guides you through a course starting from Company A and ending at Company B. After turning towards Shinjuku at the intersection of the industrial park entrance on Ome Kaido, press the I start button and go down. ” Record the introductory guidance. Since drivers often know the area around the starting point, they decide on a starting point that serves as a landmark and record the above-mentioned introductory guidance in order to start the guide song from there. After recording the intro guidance on the above tape, microphone switch 268?
When turned off, the process proceeds to step A7, and after the above introductory guidance, the stop code 5TOP is entered as shown in Figure 3.
is written, and the tape is stopped in step A8. When the tape stops, the process advances to step A9, where the hold state is maintained until the I start key 4 is operated.

After recording the intro music dance as described above, the intro music is played by driving a car to the memorial location, and at that point, in this example, "turning from the industrial park entrance intersection towards Shinjuku". ”, operate 1 start key 4.

When the start key 4 is operated while waiting for key human power in step A9, a start command is given to the cheap record 24 from the CPU 22 via the interface 23, and the Stellar 7'
Start the tape as shown in Alo. Then, in step All, the I start code 5T-1 is set to 1 as shown in FIG. 3, and the tape is stopped in step A12. Next, proceed to step A13, and proceed to step A13.
A reset signal is sent from the PU 22 to the counter 31 to reset its contents. This car/rear 31 counts the pulses given from the main pulse generating circuit via the dirt circuit G every time the car travels a certain distance.

Therefore, the distance traveled by the car is indicated by the count 1 of the counter 3. When the counter 31 is reset in the above Stella f AH, Step.

f Proceed to A, , turn on the microphone switch 26S,
The system is in a state of waiting for human input to signal the stop key 6 and end key 7. Then, when the user turns on the microphone switch 26B at an arbitrary point as the car travels and speaks at a landmark, the words are recorded.

That is, when the microphone switch 26B is turned on in the halt state of step A140, the process proceeds to step A15, where a transfer command is sent from the CPU 22 to the f-) circuit G3, the count value of the counter 310 is sent to the memory 28, and the CPU 22 is written to the address specified by . Next, in step A16, the tape is started, and the process continues in step A17 until the microphone switch 26B is turned off.
It is maintained in a recording-enabled state as shown in . Therefore, in this state, refer to the landmarks visible from the car and say, for example, ``If you see a tank on your right, turn right at the next traffic light.''
If you speak the contents of the guidance, such as this, it will be recorded on tape as ``Guidance 1'' as shown in Figure 3. In this case, it is possible to record not only the guidance (but also BGM, etc.). After recording all of the above-mentioned guidance, turn off the microphone switch 26B. When the microphone switch 26S is turned off, the process advances from step AI7 to step All+, and the above-mentioned Write a stop code after "Guidance 1".Then, after stopping the tape in step A19, return to step A14.In the same manner, turn on the microphone switch 26B at an arbitrary point and speak the mark. As shown in Figure 3, "Guidance 2", "Guidance 3", etc. can be recorded on tape. Also, when performing guidance recording as described above, each time the microphone switch 26B is turned on, the As a result of the AIS processing, the quant values of the counter 3) at that time are sequentially written into the memory 28 as shown in FIG.

However, when driving on an expressway on the way to the destination, guidance is not required from the interchange to the exit, so the stop key 6 is operated when entering the interchange. When the stop key 6 is operated, the process proceeds from step AI4 in FIG. 5 to step A2°, and the tape is started, that is, the tape of the tape recorder 25 is driven to run.

After writing the end code END on the tape as shown in step A21, the tape is stopped in step A22. In this state, a halt state is entered as shown in step A23.

Then, the user operates the H start key 5 just before the exit of the expressway interchange. When this ■start key 5 is operated, the CPU 22 moves from step A23 to step A2.
Proceed to step 4 to start the tape, and at step 70A25, enter the start code 5T-11 as shown in Figure 3.
t-tape, then the above step 7'A1
Proceed to step 2. Step with Al! The following processing is performed as explained in the above I start, and the microphone switch 26S
By turning on, it is possible to record guidance such as, for example, ``After exiting the Kofu Inter exit, please proceed to Katsunuma direction ■1.''

After arriving at the destination, the user operates the end key 7. By operating this end key 7, steps 7'A2. Proceed to and write the distance start code DS on the tape.
Write T. Next, the process proceeds to step A2γ, where the memory 28
The distance data stored in (1) the start point and (2) the distance data from the start point to the respective ID recording points are read out to the interface 23 via the gate circuit G1 and written on the tape as shown in FIG. In addition, ST21
' As shown in A28, the end code END is written on the i-tape following the distance data, and the guidance recording is completely completed.

Next, an explanation will be given of the operation when the guidance tape recorded as described above is used and the guidance content is reproduced in accordance with the driving of the car, with reference to the flowchart shown in FIG. Operate playback key 3 when starting Company A. By operating the playback key 3, the playback flow shown in FIG. 6 is started, and the tape is first started at step fA1. Next, in step B2, the tape recording contents are read to the interface 23, and the distance start code D is read.
Distance data from ST to end code END "! is written to memory 28 by interface 23. After that,
Proceeding to step B3, the tape is completely rewound and set at the start code STC position. Then, in this state, the tape is started and the intro guidance is played back as shown in step fB4, and at the same time, the presence or absence of a stop code is determined by step B5. Proceed to 776B6 and make a CH ff stop, then enter the halt state of step B7 at the trench where I start key 4 or ■ start key 5 is operated.The driver will drive the car toward the start point specified by Ignus when the above intro is displayed. , and when you reach the designated point, operate the I start key 4. When you operate this ■ start key 4, proceed to step B8, and proceed to ■
It is determined whether or not the start flag IF is set. If the 7-lag IF is set, it is a key operation error and the process returns to step B7. (2) If the start flag IF is not set, proceed to step fB9 to start the tape, read the l start code at step BIO, and then stop the first f at step fB2.

Then, as shown in step B1□, the I start flag IF is set, and in step B111, the counter 31f is reset. This counter 31 sequentially counts up according to the distance measurement each time the car travels a certain distance. Whenever the distance pulse is generated, a comparison command is given to the comparator circuit 30 in step B14, and the existing count of the color/return 31 is compared with the distance data stored in the memory 28. At this point, the distance data stored at the top address, for example "7", is read from the memory 28 and compared with the contents of the counter 3. If the comparison results do not match, the process proceeds to step B15, where it is determined whether the forward key 8, the pack key 9, and the inclination key 10 have been operated.If none of the keys have been operated, step B14 is performed. Return to

Then, as the car travels, the counter 3 counts up, and when the count 1 matches the number 7 read out from the memory 28, the process advances to step fB16, the tape is started, and the [guidance 1j] Play content. Next, the program advances to Stella 7' 1317, where it is determined whether there is a stop code and an end code. If no code is detected, the process returns to step B17 via the forward key 8 and pack key 9 operation determination step Bzs'. and,
When this Stella f13iy detects a stop code, the process advances to step 8111 to stop the tape, and at the same time, in step 819, the forward flag is set to FF.

It is determined whether the pack flag BF is set. If neither of the above flags FF and BF are set, the process advances to step B26 and the address register 29 is set.
The content of is incremented by "+1" and the next address in memory 28 is specified. Thereafter, the process returns to step nu, and the data r 15 Ji at the address specified by the address register 29 is read from the memory 28 and compared with the count value of the counter 31 . When the car reaches a point where the count value of the counter 31 and the distance data read from the memory 28 match, the tape is started and the contents of "Guidance 2" are reproduced. The contents of the Ignus will be played back as the car moves forward in the same way as under J-So. The driver then drives the car according to the audio guidance provided by playing the tape. Then, when the car advances to the intersection of the designated speed road and completes the guard against the start, the end code is read from the tape. This end code is read.

By doing so, the program proceeds from Stella 7'' B17 to step B21 and the tape is stopped. Next, in step B22, the I start flag IF and ■ start flag IIF are set.
Determine which of the following is set. ■If the start flag IF is set, return to step B7;
(2) If the start flag nF is set, all processing ends. At this point, the I start flag IF is set, so the process returns to step BT and the next key input is started. Since the ignition is not necessary on the expressway, the tape remains in a stopped state until the start key 5 is operated next time. Then, when the car reaches the exit of the interchange, Dry Nogu operates Start Key 5. Stella fB2g is started by operating this ■Start key 5.
2) It is determined whether or not the start flag IF is set. If the flag IF continues to be set, this means that the key has been erroneously operated, and the process returns to step B7.

■If the scoot flag IF is set, step B
Go to step 24 and start the tape. Then, in step B2S, when the start code 5T-II is detected, the program proceeds to the Stella fB26 and stops the tape.

Next, proceed to STETSU 7' B27 and press ■Start flag [
Cent F and reset the start flag IF. Thereafter, the program proceeds to Stella fB13 and resets the counter 3). Thereafter, guidance processing is performed in accordance with the driving of the vehicle, as in the case of the above-mentioned I start. and,
When the car approaches the destination, the last dance is played, and then the end code is read out.

When this end code is read out, the process advances from step B17 to step B21 to stop the tape, and then in step Ihz, gf in the flag is determined. At this point ■
Since the start 7 lag ■F is set, the guidance ends.

Next, a description will be given of correction processing when the guidance content is advanced or delayed during the above-mentioned guidance traveling. For example, [You can see the Stank on your right. ”, but when you listen to the sound and say that the tank was short, it means that the car's distance count is behind the standard, so in this case, operate the forward key 8 to read the car's distance count. Proceed. For example, in Figure 3, “
Suppose that "Guidance 2" is the above-mentioned "...gas tank...", and when this guidance is given, it is noticed that the vehicle has already passed the gas tank. Therefore, the force 9 counter 31 at this time counts "15",
Assume that the address designation of the memory 28 is also "15", but the reference distance is "17" because it is past r15J' at the time of recording. Therefore, if the forward key 8 is operated while the guidance is being uttered, the operation of the forward key 8 is detected in step 132g, and the process proceeds to step B29, where the forward flag FF is set. Then step B
Returning to step 17, the presence or absence of a stop code and an end code is determined.O Then, when a stop code is detected in step B17, the tape is stopped in step BL8, and then the process proceeds to step B19, where the forward flag is set to FF.

The presence or absence of the back flag BF is determined. This step 81
When the forward flag FF is detected in step 9, the process proceeds to the forward correction flow shown in FIG. First, in the step itself, the memory address held in the address register 29 is incremented by "+1" and the distance data "33" is transferred from the memory 28.
” is read out. Then, the process proceeds to step C2, where the CPU 22 outputs a preset signal, and the distance data "33" read out from the memory 28 is preset in the counter 3 to keep it in a count stop state.

After that, go to Stella fC, start the tape, and
Contents of "Guidance 3" For example, if you play "Please turn left at the intersection called Nishiharamachi." and detect the stop code that follows the guidance above in step C4, step:
At fC5, Q7'' is stopped.Then, as shown in step C6, the contents tr of the address register 29 are
+IJ to set the memory 28 to 150'', and then hold it in the halt state in step C7.

On the other hand, the driver drives the car according to the above-mentioned guidance self-answers, and operates the restart key 11 when he confirms the "Nishihara-cho intersection" indicated by the guidance. By operating the restart key 11, the process advances from step C7 to step C8, where the third counter starts counting, the forward flag FF is reset, and the sixth counter starts counting.
Return to step B14 in the figure. Through the above processing, the contents of the counter 31 are changed to r at the point where the restart key 11 is operated.
33J, the memory 28 designation becomes "50", and the forward correction ends.

Further, the forward key 8 may be pressed not during the guidance utterance but after the guidance utterance is finished.

In this case, in step BI5, the forward key 8
The operation is detected, and the process proceeds to step C2 in FIG. In other words, if the forward key 8 is operated after the guidance utterance is finished, the operation of the forward key 8 is detected in the step BIS after the memory address update process in step B20 is finished, so the memory address update process is not necessary. , forward correction processing is performed from step C2. The pond is the same as in the above case.

Also, if the interior of "Guidance 2" above, "You can see the Stank on your right hand side," is played but you still can't see the Stank, it means that the distance count of the car is too fast, and in this case, - Operate Gutsuku key 9 to delay the distance count. In Figure 3, the above “Ignus 2
" is uttered but the f-stank is still not visible, the first shift of the counter 31 is "15" and the memory 28 is also designated "1.
5". Assume that the actual position at this time is "13". If the distance count of the car is too fast as in this case, operate the back key 9 while "Ga Idance 2" is being uttered or after the utterance is complete. If the pack key 9 is operated while the guidance is being uttered, the operation of the pack key 9 is detected in step 82g of FIG. 6, and the process proceeds to step B30, where the back flag BF is set. Thereafter, the process returns to step B17, and when a stop code is detected, the tape is stopped in step 13ts.

When the back flag BF is detected in step B1G, the process proceeds to the back correction flow shown in FIG. Furthermore, if the puck key 9 is operated after the utterance of "guidance 2" is finished, the operation of the puck key 9 is detected in step 815, and the eighth
In the back correction flow shown in the figure, first, the counter 3) is stopped as indicated by Stella fD1, and the system returns to a halt state in step D2. Thereafter, when the car moves forward and the driver sees the start/stop indicated by the guidance, the driver operates the restart key 11. By operating the restart key 11, the process advances from step D2 to step D3, and the counter 31 starts counting. After that, STETSU 7
In step D4, it is determined whether there is a pack flag BF, and if there is a back flag BF, in step D5, the contents of the address register 29 are set to "+1" and the memory 28 is designated as "33", and then the step shown in FIG. The process returns to B14, and if there is no pack flag BF, the process immediately returns to step B14 from step D6.

That is, if the pack key 9 is operated while the guidance is being uttered, the memory address update process in step BIIO is often performed, and the process proceeds from step 819 to the pack correction flow in FIG. 8, so the memory address is not updated in step Ds. Update. In addition, if the pack key 9 is operated after the guidance ends, the memory address update process for Stella f B, o is performed, and then the process proceeds from step B15 to the pack correction flow shown in FIG. 8, so the memory address update process in step Ds is performed. I think it is unnecessary. After operating the start key 9 as described above, the actual position can be determined by operating the restart key 11 at a point that matches the guidance, that is, at a point where the step is visible in the above case. When it reaches "15", the count value of the counter 31 becomes "15", the designation of the memory 28 becomes "33" indicating the next dance point, and the correct proneness is corrected.

Further, when the driver is running on the above-mentioned guidance and wants to run on an unscheduled course, such as when searching for a gas station, the guidance process is temporarily interrupted by operating the interaction key 10. The operation of the interactive key 10 is detected in step B1g of FIG. 6, and the process proceeds to the interactive processing flow of FIG. 9. First, step El
As shown in FIG. 2, the counting operation of the counter 3 is stopped, and this state is maintained in step E2.

Then, the driver operates the restart key 11 when returning from the unscheduled course to the scheduled course. By operating the restart key 11, the process advances from step E2 to step E3, where the counting operation of the counter 3 is restarted, and then the process returns to step B17 in FIG. Through the above processing, even if the vehicle runs on an unscheduled course, it is possible to continue the normal guidance operation when the vehicle returns to the scheduled course.

[Second example] Next, a second embodiment of the present invention will be described.

FIG. 10 shows the operation panel IA in this second embodiment. It is provided with a start key 11, a check key 12 for correcting guidance errors, and a monitor key 13 for opening one set of recording information in advance. In this second embodiment, the error in Igunsu's utterance timing is corrected by operating the check key 12 at a predetermined check point, and the error correction forward key 8 and pack key 9 in the first embodiment are used. It's not necessary.

Note that this second embodiment shows a case where one start key 4k is provided.

Section 11 indicates the format of the tape with checkpoints. At the time of recording the guidance, the check key 12 is operated at a predetermined check point, and the check guidance, for example, ``We're right next to Tokyo Tower.'' is recorded. As a result of the above operations, a check code CH and a check code CHG are recorded on the tape between normal guidance ignition 2 and guidance 3, as shown in FIG.

Further, the distance data at the checkpoint when the check key 12 is operated, for example "24", is written in the memory 28 as distance data for normal guidance, and is also written in the memory 28 as checkpoint data.
is written in the check area. Distance data and checkpoint data CH-D stored in this memory 28
is written on the tape as shown in FIG. 11 at the end of guidance recording.

The twelfth position is a flowchart when the check is played back, and is a part that replaces step B2 in the flowchart of FIG.

During tape playback, when the tape starts at step:, -y''B in FIG. 6, the distance start code DST recorded on the tape as shown in step 8201 in FIG.
The data between the end code END and end code END is read into the interface 23, and among the read data, the distance data is written to the memory 28 in step B2゜2, and the checkpoint data is written to the check area of the memory 28 in step 8203. . Thereafter, the process returns to step B3 in FIG. 6, and the processing operations described above are executed. In this case, Stella f B,, lc check code CH
◎ On the other hand, when the check code CH is detected, check 7 lag is set and the process returns to step B14. ◎ On the other hand, when the check code CH is detected, check 7 lag is set and the process returns to step B14. When you arrive at the location, that is, "right next to Tokyo Tower", operate check keys 1 and 2. This operation of the check key 12 is detected at step BIS in FIG. 6 and branches to the correction flow shown in FIG. 12(B). In this modification flow, first, as shown in step B211, the memory 2
Checkpoint f stored in the check area from 8
Read out the count data C) ID, for example "24", and set it in the counter 31. Then, as shown in step B21□, the tape is set at the position where the check code CH is stored. Next, the process proceeds to step B213 to determine the presence or absence of a check flag, and if the check flag is set, the process proceeds to step 82.4 where the memory address is decremented. In other words, if the check flag is set, the check flag has already been uttered and the memory address has been incremented in Stella 7' B10, so in this case, step B above is executed.
As shown in 2.4, the memory address held in the address register 29 is set to "-1" and the check flag is reset. Thereafter, the process returns to step B14 in FIG. If it is determined in step B213 that there is no check flag, the process immediately returns to step B14 in FIG. 6.

When the process returns to this step 7'B14, the value of the counter 31 is "24" and the designation of the memory 28 is "24", so a match between the two is detected in step B14, and the process proceeds to step 13ta. In this step BI6, all the chi f are started, and the check is made to utter Ignsu.

By operating the check key 12 at a predetermined position as described above, the counter 31, memory 28, and tape position are corrected so that they match, and the check mark is uttered.

[Third Embodiment] FIG. 13 shows an embodiment of the tape format. Figure 13 (A) is an example in which the distance data for the l start and ■ start are recorded before the guidance, and Figure 13 (A) is an example in which the distance data for the l start and the ■ start are recorded before the guidance. This is an example in which ■ start distance data is recorded before ■ the start dance. Moreover, FIG. 13(C) is an example in which each distance data is recorded before the corresponding guidance. Note that in FIG. 13, codes such as start, stop, and end are omitted.

[Fourth Embodiment] Although each of the above embodiments records information on a tape at distance count 1, the Honmaru embodiment uses a cassette tape 41, RAM 42, A pack 44 is constructed using a power supply 43 for the park and quag, and distance count information is stored in the RA and V142. The above-mentioned A hook 44 is used by being inserted into the main body. Furthermore, the RA and M 42 may have only a memory, or may have a counter area.

[Fifth Embodiment] While the first embodiment requires the start key 4.5 to be operated in the order of I → Step B in Figure 15 (A)
1゜l and step 823 ~ Bzyt
``Replaced with Stella fB102 in Figure 15 (B), ■.
