Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a route guidance device that is mounted on a motor vehicle and guides the route to a destination.

[Prior art and its problems]

2. Description of the Related Art Various types of route guidance devices that are mounted on automobiles and provide directions to a destination have been considered in the past, as shown below.

(1) As shown in Japanese Patent Publication No. 56-33758, a route guide for right turns, left turns, etc. is displayed on the i4 panel of the driver's seat of a car, and the driver is driven according to the guide.

(2) Utility Model Publication No. 44-501, Utility Model Publication No. 46-249
As shown in Japanese Patent Publication No. 48-48 and Japanese Patent Application Laid-open No. 48-481 '08, route guidance is recorded in advance on a magnetic tape, and by playing it back, the driver drives a car according to the voice guidance. That's what I did.

(3) As shown in Japanese Patent Application Laid-open No. 46-6066,
A magnetic tape is intermittently driven to record guidance every specific distance traveled by the car, for example, every 2 km, and the next time the vehicle travels on that road, the magnetic tape is played again every specific distance traveled and the guidance is uttered. What I did.

As described above, various types of route guidance devices for automobiles have been considered in the past. However, in the conventional route guidance device described above, the guidance sections are not divided, and once the guidance operation is started, a series of guidance continues until the destination9, which causes the following problems. .

(1) For example, when traveling a long distance with an expressway along the way, guidance is not required during that time. It is wasteful to count the distance of each section where guidance is not required and compare it with the guidance position, and the error increases.

(2) If you misunderstand the guidance instructions and take a wrong turn even once, such as by turning left instead of right, the relationship between distance and guidance will be disrupted, and all subsequent guidance will be meaningless. Become.

[Purpose of the invention]

The present invention has been made in view of the above points, and it is possible to suspend useless guidance processing on long distance sections where the route is clearly known, and even if you get lost along the way, you can set a preset An object of the present invention is to provide a route guidance device that can provide effective guidance from two starting points.

The above-mentioned pulse generation circuit generates a pulse every time the car travels a certain distance.
The output pulse is sent to the CPU 2 in addition to the counter 31 mentioned above.
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 tape, an ordinary music player f 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
The U 22 sends a recording mode signal and a start command to the tape recorder 25 via the interface 23, and drives the magnetic chip f as shown in step A of FIG.

Next, the process proceeds to step A2, where a start code STC is written on the magnetic tape as shown in the tape format of FIG. When writing of the start code STC is completed, the running of the tape is stopped as shown in step 7'A, and the process proceeds to step A4, where the state is maintained until the microphone switch 26S is turned on. In this state, if you turn on the microphone switch 26Sf,
The tape starts running as shown in step A6, and then the running state of the tape is maintained as shown in step A6 until the microphone switch 26S is turned off. During this time, the intro guidance is recorded. For example, an intro that says, "This tape will guide you through the course starting from the full start of Company A to Company B. Please press the 1st start button when you turn to Shinjuku Mando at the intersection of Ome Kaido Industrial Park Entrance." Record guidance. Since drivers often know the area around the starting point, they record the above-mentioned introductory guidance in order to decide on a landmark starting point and start guiding from there. After recording the intro guidance on the above tape, switch the microphone switch 2.
When 6Sf is turned on, the program advances to Stella fA7, where after the above-mentioned intro guidance, the code 5TOP of S1-7 is written as shown in FIG. 3, and the tape is stopped at step A8. When the tape stops, the process advances to step A9 and remains in a halt state until the lx tart key 4 is operated.

After recording the introductory guidance as described above, drive the car to the location indicated in the introductory guidance, and at that point, in this example, "turning from the industrial park entrance intersection toward Shinjuku Mando" Operate start key 4.

When the 1 start key 4 is operated while waiting for key input in step A9, a start command is given to the tape recorder 24 from the CPU 22 via the interface 23, and the tape is started as shown in step AIO. and,
In step A, as shown in FIG. 3, I start code 5T-1 is written, and the tape is stopped in step fA1□. Next, proceed to Stella 7°A13 and CP
A reset signal is sent from U 22 to counter 31 to reset its contents. This counter 31 changes the pulse generation circuit to the dirt circuit G2 every time the car travels a certain distance.
' Count the zorus given through '. Therefore, the count value of this counter 31 indicates the distance traveled by the car.

When the counter 3 is reset in step A13, the process proceeds to step Att, where it waits for the microphone switch 26S to be turned on and signals input to the STOZZO key 6 and the ENTER key 7 to be input.

Then, if the user turns on the microphone switch 26Sf at an arbitrary point as the car travels and speaks at a landmark, the words are recorded. That is, when the microphone switch 268 is turned on in the halt state of step A14, step AIM
Then, a transfer command is sent from the CPU 22 to the dirt circuit G3, and the count value of the counter 3 is sent to the memory 28 and written to the address specified by the CPU 22. Next, the tape starts at Stella 7'A16, and the tape is steered until the microphone switch 268 is turned on.
:'A As shown in 17, it is maintained in a recordable state. Therefore, in this state, if you refer to the landmarks visible from the car and give guidance such as, ``When you see the gas tank on your right, turn right at the next traffic light,'' the guidance will be as shown in Figure 3. This will be recorded on tape as "Guidance 1". In this case, not only guidance but also BGM
etc. can also be recorded. After recording the guidance, the microphone switch 268 is turned off. When the microphone switch 26Sf is turned off-r, the steps start from step A17.
Proceed to y7'Atg and write the strike and near code after the above "Guidance 1". Then, after stopping the tape at step A19, the process returns to step AI4.

In the same manner, by turning on the microphone switch 26S at any point and speaking at the landmark, "Guidance 2", "Guidance 3", etc. can be recorded on tape as shown in Fig. 3. can. Also, when performing guidance recording as described above, each time the microphone switch 268 is turned on, the step! Depending on the processing of A15, counter 3 at that time
A count value of 1 is 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 driver operates the strag key 6 when entering the interchange. When the strag key 6 is operated, the process advances from step A2o in step A2o of FIG. )” After writing END, step, no A
The tape is stopped at 22. In this state,
The vehicle enters a halt state as shown in fk23. Then, just before the expressway exit, operate the start key 5. 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 in step A25 write the start code 5T-It on the tape as shown in FIG. 3, then proceed to step A, 12 described above. The following processing is performed as explained in the above I start, and the microphone switch 268
By turning it on, you can record guidance such as ``When you exit the Kofu Interchange, proceed toward Katsunuma.''

After arriving at the destination, the user operates the end key 7. By operating this end key 7, proceed from step A14 to Stella 7'A21i'', and write the entire distance start code DST on the tape. Next, proceed to step A27.
The distance data stored in the memory 28, the pick, ■the start point, and the distance data from the ■start point to each guide recording point are sent to the interface zsK via the dart circuit Glk.
'R1J3 and write to tape as shown in FIG. Further, as shown in Stella 7'A211, an end code END is written on the tape following the distance data, and the guidance recording is ended.

Next, an explanation will be given of the operation when the guidance tape recorded as described above is used to reproduce the guidance content in accordance with the driving of the vehicle, 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 starts the tape at (start)L, if, step Al. Next, in the Stella fBi, the tape recorded contents are read to the interface 23, and the distance start code D is sent.
Distance data from ST to END is convoluted into the memory 28 via the interface 23. Thereafter, the process proceeds to step B3, where the tape is rewound and set at the start code STC position. Then, from 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 strike chord is determined in step B5. When the STEP code is detected in this STEP BS, the program advances to STEP B6 to play the tape, and then enters the STEP fB7 halt state until either the 1 start key 4 or the 2 start key 5 is operated. The driver drives the car toward the start point specified by the introductory guidance, and operates the I start key 4 when the driver reaches the specified point.

When this ① start key 4 is operated, the process advances to step B8, and it is determined whether the ① start flag JF is set. If the flag IF is set, it is a key operation error, and the process returns to step B7. ■If the start flag IF is not set, proceed to step B and step 7.
Start the 1st start coat 9 at Ste, No B1°, Rlf:iL, and then strike the chi f with the Stesono Bit. Then, as shown in Stesono B12, the I start flag IF is set, and at the same time, the counter 31f is reset at Stesono f3t3. This counter 31 is sequentially incremented by a distance pulse every time the car travels a certain distance. Whenever the above-mentioned distance/gurus occurs, a comparison command is given to the comparator circuit 30 in the stesonometer 814, and the contents of the counter 3 and the memory 2 are
Compare the distance data stored in 8. 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 this comparison result does not match, Stella 7'B15
Proceed to and determine whether any of the forward key 8, back key 9, or interrog key 0 is operated,
If no key is pressed, return to Stella fB. Then, as the car runs, the counter 3 starts counting.

The count value and the read value 1-7 from the memory 28
”, proceed to STEP B16, start the entire tape, and play the guidance IJO internal answer. Next, proceed to STEP B17, and determine the presence or absence of the 7-g code and end code. No falling code is detected. In case,
Forward key 8, back key 9 operation determination stay 7'
Return to Stesono 817 after 13ts. And this Ste7noB! At 7, Stotnoko p < Stella when detected: 7
The program proceeds to step B, 8, where the tape is loaded, and at step K, step 13ts, it is determined whether the forward flag FF and back flag BF are set. Both 7 above
If neither lug FF nor BF is set,
Proceed to Stesono B20 and read the contents of address register 29 k
r+1]t, , specifies the next address in memory 28.

Thereafter, the process returns to step:/'B14, data "15" at the address specified by the address register 29 is read from the memory 28, and the count value of the counter 31 is compared. 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.

Thereafter, the same guidance is reproduced as the υ vehicle advances by the same operation. The driver then drives the car according to the audio guidance provided by playing the tape. When the car advances to the expressway intersection and completes the I start dance, the end code is read from the tape. By reading this end code, it moves from Stella fB+7 to StereoB21,
Play the tape. Next, in the Stesono B22, it is determined which of the 1 start flag IF' and the U start flag IIF is set. If the I start flag ■F is set, the process returns to step B7; if the start flag ■F is set, all processing ends. At this point! Since the start flag IF is set, return to Stella fB7 and prepare for the next keystroke. Since guidance is not required on expressways, the tape remains in a stopped state until the start key 5 is operated next. The car then proceeded to the interchange exit.7
For dry 9 at the time of emergency, ■operate start key 5. This ■Operation of the start key 5 proceeds to Sistera f B 23, and determines whether or not the ■Start flag IF is set.If the flag IF is not set, it means that the key was operated incorrectly, so go to STETSUNO B7. return. Isf
If i-door, y-gu IF is hit, step B
Go to step 24 and start the tape. Then, when the start code 5T-17 is detected by the STETSUNO 82S, the program proceeds to the STETSUNO B26 and starts the tape.

Next, the process advances to step B27, where ■ start flag tIF
is set, and one start flag IF is reset. After that, proceed to Stesono Bts and reset counter 3.

Thereafter, guidance processing is performed according to the driving of the car, similar to the case of the summer start. Then, when the car approaches the destination and the final guidance is played, the end code is subsequently read. When this end code is output one after another, the process advances from the Stesono BIT to the StenoB21 to stop the tape, and then the entire flag content is determined in the StesonoB22. At this point, the U start flag IIF
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 driving. For example, when you hear the guidance, "You can see the gas tank on your right," and it says that the gas tank was there earlier, it means that the car's distance count is behind the standard, so in this case, press forward key 8. Operate to advance the distance count of the car. For example, in Figure 3, “
Suppose that the woman got married at the above-mentioned "Guidance 2" at "...gas tank..." and when this guidance was given, she realized that she had already passed the gas tank. Therefore, counter 3J at this time counts "rxs" by 1,
Assume that the address specification of the memory 28 is also "15", but the reference distance has passed "15" at the time of recording and has become "17". Therefore, while the guidance is being uttered, press the forward key 8.
When the forward key 8 is operated, the operation of the forward key 8 is detected in step 13zs, and the process proceeds to step B211, where the forward flag FF is set. After that, Stesono 8
It is determined whether there is a return to step 17, a strike, an f code, or an end code. Then, when the stator code is detected in this step B17, the tape is completely stopped at the stesono 13is, and then the process proceeds to the stesono B1G where the forward flag FF is set.
The presence or absence of the puncture flag BF is determined. This Stesono B1
When the forward flag FF is detected in step 9, the process proceeds to the forward correction flow shown in FIG. First, in the stesono cl, the memory address held in the address register 29 is incremented by "+1" and the distance gutter is "3" from the memory 28.
3" is read out. Next, the process proceeds to step C2, where the CPU 2
2, a reset signal is outputted, and the distance 1lI7'-ta "33" read from the memory 28 is transferred to the counter 3, and the count is held in a stopped state. after that,
Ste.

Proceed to Guidance C3, start the tape, and read “Guidance 3”
For example, please turn left at the intersection 1-Nishiharacho. '' is played back, and when the stew code following the guidance is detected at stethoscope c4, the tape is stopped at stethoscope c5. Then, as shown in step 7'c6, the contents of the address register 29 are 'kr+IJ',
Specify memory 28 as '1r50J, then step C
7, it is held in the halt state. On the other hand, the driver drives the car according to the above-mentioned guidance contents, and operates the restart key 51 when he confirms the "Nishihara-machi intersection" indicated by the guidance. By operating this restart key 11, the count operation of the 3 launch counters is started from the system stage C7 to the system stage C8, and the 1 forward flag FFf is reset, and the system stage B14 in FIG.
Return to After the above processing, the content of the counter 31 is "33" and the memory 28 is at the point where the restart key 11f is operated.
If the specification of is "50", 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 B15, the forward key 8
The operation is detected, and the process proceeds to step C2 in FIG. In other words, if you operate the forward key 8 after the guidance voice is finished, after completing the memory address update process for Stella: 7''B2G, the forward key 8 is
Since the operation is detected, there is no need for memory address updating processing, and forward correction processing is performed from step C2. Other details are the same as in the above case.

In addition, if the content of "Guidance 2" above, "You can see the gas tank on your right hand side," is played but you still cannot see the gas tank, the distance count of the car is too fast, and in this case, back up. Operate key 9 to delay the distance count. In Figure 3, the above "Guidance 2"
is uttered but the gas tank is still not visible, the value in counter 3 is "15" and the specification in memory 28 is also "15".
It becomes. At this time, it is assumed that the actual position is "13" which is rare. If the distance count of the VC car is too fast, operate the back key 9 while "Guidance 2" is being uttered or after the utterance is finished. If you operate the back key 9 while the guidance is being uttered, Stella f in Figure 6
B2. The operation of the back key 9 is detected at step 13so, and the back flag 8F is set. Thereafter, the process returns to step B17, and when a stop code is detected, the process is stopped in step 81+1. When the pack flag BF is detected in step B111, the process proceeds to the pack correction flow shown in FIG. Also,
If the back key 9 is operated after the utterance of "Guidance 2" is finished, the operation of the back key 9 is detected in step BI5, and the process proceeds to the pack correction flow shown in FIG. In this pack correction flow, first, as shown in step fDl, the counter 3 (il-) is stopped, and the car enters a halt state in step D2.Then, as the car moves forward and the gas tank indicated by the guidance is seen, Drinos operate the restart key 11f. By operating the restart key 11-, the process proceeds from step D2 to step D3, and the counter 31 starts counting. Thereafter, step D
In step D5, it is determined whether there is a mark lag BF, and if there is a mark BF, in step D5, the contents kr+IJ of the address recorder 29 are set to specify the memory 28.
33'', the process returns to step B14 in FIG. 6, and if there is no back flag BP, the process immediately returns to step B14 from step D5. In other words, if the back key 9 is operated while the guidance is being uttered, the memory address update process in step B20 is not performed, and steps from step f81g to the eighth step are performed.
Since the process proceeds to the pack modification flow shown in the figure, the memory address is updated in step D. In addition, if the back key 9 is operated after the guidance ends, the memory address update process in step Bzo is performed, and then the process proceeds from step 815 to the mark correction flow in FIG.
The memory address update process in step 5 is no longer necessary. However,
After operating all the bank keys 9 as described above, the actual position can be changed by operating the restart key 11 at a point that matches the guidance contents, in the above case, the point where the gas tank is visible. 15", the counter 31
The count value is "15" and the designation in the memory 28 is "33" indicating the next guidance point, and the state is corrected.

Further, during the above-mentioned guidance driving, when driving on an unscheduled course, such as when searching for a gas station along the way, the guidance process is temporarily interrupted by operating the INTERAT key 10. The operation of the interrat key 10 is detected at step L7'B15 in FIG.
Proceed to the increment processing flow shown in the figure. First, Ste.

! As shown in E1, the counting operation of the counter 3) is stopped, and this state is maintained in step E1. Then, when the driver returns from the unscheduled course to the scheduled course, he operates the restart key 11f.

By operating this restart key 11, the process advances from step E2 to step fE3, 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 returning to the scheduled course.

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

FIG. 10 shows the operation/main panel 7A in this second embodiment. Guto key 10, restart key 11,
It is also provided with a check key 12 for correcting guidance errors and a monitor key 13 for listening to recorded information once in advance. In this second embodiment, errors in guidance voice timing are corrected by operating a check key 12 at predetermined check points, and the forward key 8 and back key 9 for error correction in the first embodiment are No longer needed.

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

FIG. 11 shows a tape formatter provided with checkpoints. At the time of recording Ida/su, operate the check key 12 at a predetermined checkpoint and record the check and cue guidance, for example, ``We have come right next to Tokyo Tower. As shown, a check code CH and a check guidance CHG are recorded between normal guidance, for example, guidance 2 and guidance 3.
Distance data, for example "24", at the checkpoint when the travel key 12 is operated is written in the memory 28 as distance data for normal guidance, and is also written in the check area of the memory 28 as checkpoint data. The distance data and the check data Cf(-D) stored in the memory 28 are written to the tape as shown in FIG. 11 at the end of the guidance recording.

Figure 12 (4) is a flowchart when playing check guidance.
This is the part that can be replaced with 2.

Chee! During playback, when the tape starts at step Bl in FIG. 6, the data gain tough between the distance start code DST and end code END recorded on the tape is set to 23 as shown in step B201 in FIG. Among the data read above, the distance data is written to the memory 28 in the step f8202, and the checkpoint data is written to the memory 28 in the step fBzoa.
Write in the check area of 8. Thereafter, the process returns to step B3 in FIG. 6, and the processing operations described above are executed.

In this case, a check code CH determination function is added to step 828, and when a check code CH is detected, a check flag is set and the process returns to step fB.

- 10,000, the driver operates the check key 12 when the car comes to the location specified in the check guidance CHG, that is, "right next to Tokyo Tower." This operation of the check key 2 is detected by the steps fB and s in FIG.
The process branches to the modification flow shown in Figure 2 (B). In this correction flow, first, as shown in step:)'7'B211, check point data CH-D, for example "24", stored in the check area is read from the memory 28 and set in the counter 3. Then, as shown in step B212, the check code CH is set to the stored position. Next, the process proceeds to step B21g, where it is determined whether or not there is a check flag, and if the check flag is set, the memory address is decremented at step B2.4. If the check flag is set, the check guidance has already been uttered and the memory address has been incremented in step Bzo, so in this case, the above Stella 7'
As shown at B214, the memory address tJ-1 held in the address register xp29 is set and the T/T flag is reset. After that, step B14 in FIG.
Return to In addition, if it is determined in step B213 that there is no check flag, immediately check the Stella 7'13 in FIG.
Return to 14.

When returning to this step BI4, the value of the counter 31 is "24" and the specification of the memory 28 is "24", so a match between the two is detected in step B14,
Proceed to step B111. In step BI6, the tape is started and check guidance is uttered. By operating the check key 12 at a predetermined position as described above, the counter 31, memory 28, and tape position are corrected to match, and check guidance is uttered.

[Third Embodiment] FIG. 13 shows another embodiment of the tape format. Figure 13 (A) is an example in which the distance data for I start and ■ start are recorded before the guidance, and Figure 13 CB) is! This is an example in which the start distance data is recorded before the start guidance. 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, strag, and end are omitted.

[Fourth Embodiment] While each of the above embodiments records distance count information on a tape, this embodiment uses a cassette tape 41, a RAM 42, and a buffer lag as shown in FIG. A pack 44 including a power supply 43 for use as a set is configured,
Distance count information is stored in the RAM 42. The pack 44 is used by being inserted into the main body. Further, the RAM 4 Z may be only a memory, or may have a counter area.

[Fifth Embodiment] While in the first embodiment it is necessary to operate the start keys 4 and 5 in the order of r-+n, in this embodiment steps 88 to aIg in FIG. ), steps 823 to 027 are replaced with step 8102 in FIG. 15(B), and it is possible to start from either 1 or ■. for example,
■When you take a wrong turn in a section and are unable to communicate with the guide, or ■When you know the section and don't need a guide, press ■Start key 5 at the beginning of the section. By operating this ■Start key 5, Systema 7'810
In step 2, the tape is set at the start position, and the guidance process starts from there.

In the embodiment shown in FIG. 2, the designated addresses in the memory 28 are updated sequentially each time the guidance information is reproduced, but in addition, the contents of the memory 28 are constantly searched to match the contents of the counter 3. A match with the stored contents of the memory 28 may be detected.

Further, although the above embodiment shows the case where the guidance section is divided into two, it may be divided into a larger number of sections so that guidance in an arbitrary section can be selected and performed.

〔Effect of the invention〕

As described above, according to the present invention, the guidance section is divided into a plurality of sections, and the guidance operation can be instructed to start at the start point of each guidance section. In long-distance sections, unnecessary guidance processing can be suspended, making long-distance guidance possible. Furthermore, even if you get lost on the way and the relationship between distance and guidance becomes incorrect, once you reach the starting point of the next divided section, you can start again from there and make the subsequent guidance valid. Furthermore, it is also possible to omit the guidance for the sections that are known and to start the guidance from the sections that are unknown.
