Reference numeral 22 denotes a speaker corresponding to a part of the sound reproducing means 7 in FIG. 1, which is used for blowing sound data. An operation unit 23 corresponds to the operation unit 4 in FIG.

FIG. 3 is a diagram showing the storage contents of the sound data information table of the vehicle-mounted navigation device according to the embodiment of the present invention, and is an example of the contents of the sound data information stored in the map information storage means 2. In the figure, reference numeral 25 denotes a sound data information table, which is a facility / specific area name 26, a sound data name 27, a start condition distance 28, a stop condition distance 29, a sound data reproduction time 30, latitude information 31, longitude information 32, and sound data storage. It is composed of a device number 33, a sound data storage position number 34, and a voice guidance number 35.

The facility / specific area name 26 is the name of a facility or a specific area associated with the sound data. If the first character of the data is other than an asterisk (*), the facility or the specific area related to the character string is a sound or a specific area. If the first character is an asterisk, the name of a facility or a specific area including the same character string as the character string after the asterisk is the target of sound data reproduction. For example, in the case of "airport",
Not only "Okayama Airport" but also "Okanan Airfield" and "JASDF Hyakuuri Base" are also covered. In the case of "* Airport", "Okayama Airport" is a target facility, but "Okanan Air Base" and "JASDF Hyakuuri Base" are outside the target facilities. The character string set in the facility / specific area name 26 can be associated with a plurality of facilities / specific areas by setting the values set in the latitude information 31 and the longitude information 32, which will be described later, to 0. Is added to the beginning of the character string to further limit the facility / specific area. This allows
For example, by setting the name of a convenience store chain with an asterisk in the facility / specific area name 26 and setting the jingle flowing in the commercial of the convenience store chain as the sound data, the convenience store chain stores around the country can be used. Will play the jingle automatically. Using an interchange of a highway or a parking area as the facility / specific area name 26, sound data can be reproduced even when approaching these. At this time, by adding a process of searching for a route from the current location to the shortest interchange or parking area, it is possible to avoid an interchange or parking area having a different route from being subjected to sound data reproduction.

The sound data name 27 is a character example for identifying when the user selects sound data. When registering new sound data, the user inputs the character example using the operation unit. can do. Also, when newly registering sound data using a mini disk medium having a data name in the medium such as a mini disk medium, the sound data reproducing device changes the data name stored in the medium. By taking the data and passing it to the CPU 11, the CPU 11 can also register it as the sound data name 27. Sound data recorded by the user can be used as the sound data. For example,
It is possible to edit the sound of the birds recorded using a tape recorder in the woods at home, and load the sound stored on a mini-disk medium into the sound data reproducing device 20 for use.

The start condition distance 28 is distance data serving as a reference for judging the start of sound data reproduction. The start condition distance 28 is compared with a straight line distance from the vehicle position calculated by the CPU 11 to a facility or a specific area. If 28 is larger, sound data reproduction is started.

The stop condition distance 29 is distance data which is one of the criteria for judging the stop of sound data reproduction. The stop condition distance 29 is a linear distance from the own vehicle position calculated by the own vehicle position detecting means 1 to a facility or a specific area. By comparison, if the stop condition distance 29 is smaller, the sound data reproduction is stopped.

The sound data reproduction time 30 is time data which is one of criteria for judging stop of sound data reproduction.
The sound data reproduction is stopped when it is determined that the sound data reproduction time 30 is equal to or shorter than the reproduction time from the reproduction start calculated by the PU 11 to the present time. Only when the stop condition distance 29 is designated as 0 (zero), the sound data reproduction time 30 is valid. If the start condition distance 28 and the stop condition distance 29 are set to the same value or a considerably close value, if the vehicle runs near the threshold distance of the condition for a long time,
Since the sound data reproduction and stop may be repeatedly performed frequently, it may not be practical. However, it is possible to set the stop condition distance 29 which greatly exceeds the start condition distance 28 or to set the sound data reproduction time 30 minutes. By setting, it is possible to prevent the same phenomenon from occurring.

The latitude information 31 and the longitude information 32 are data representing a sound data reproduction position designated when sound data is reproduced at a place distant from a facility or a specific area. Is stored when playing back.

The sound data storage device number 33 is data representing the sound data reproducing device 20 in which sound data is stored by a unique number in the system.
U11 is a one-digit number added in the order in which the connection statuses of all devices are checked. The sound data storage position number 34 is
This is data representing the relative position of the sound data in the sound data reproducing device 20 by a unique number in the corresponding sound data reproducing device 20, and the number added according to the order in which the sound data was recorded in the medium. It is.

The voice guidance number 35 is data representing conditions for performing voice guidance of the distance and direction of a facility or a specific area from the position of the vehicle, and it is possible to distinguish the necessity of guidance and the guidance timing by number. .

Next, the operation of the on-vehicle navigation device according to the embodiment of the present invention will be described. First, an outline of the system processing will be described with reference to FIG.
After the system power is turned on, connection check processing (step S
Perform 1). In step S1, the connection status of the sound data reproducing device 20 connected to the system is checked,
The sound data storage device number 33 is added according to the order in which the checks were performed. The device determined to be abnormal is disconnected from the system, but the number is added so that no inconsistency occurs in the sound data storage device number 33 in the sound data information table 25. After that, it cannot be used until the system is restarted. Thereafter, the process proceeds to a RAM initialization process (step S2). In step S2, the CPU 11
After the RAM 19 is once cleared to zero, the sound data information table 25 and the voice guidance number table 40 are read from the map information storage device 17 and stored in the RAM 19. Then, the system startup is completed. Then, the process proceeds to the sound data reproduction start / stop processing SUB1 (step S3).

In step S3, the map screen is displayed and the user can use the map. According to the sound data information table 25 stored in the RAM 19, the position of the vehicle and the relative distance between the facilities are measured. The sound data is reproduced according to. Here, sound data can be changed by a menu operation (step S4) using the operation unit 23. If the menu operation is not performed, step S3 remains. After performing step S4, it is determined whether the input is new sound data (step S5).
If new sound data is input, new sound data input processing SU
B2 (step S6) is performed, and if not, the existing sound data setting process SUB3 (step S7) is performed. After steps S6 and S7, a reproduction condition setting process SUB4 (step S8) for setting sound data reproduction start / stop conditions and voice guidance conditions is performed.
Move to 3.

Next, the existing sound data setting processing SUB of FIG.
A procedure for changing the setting of the sound data name 27 related to the facility / specific area name 26 registered in the system, which is a subroutine process corresponding to No. 3, will be described with reference to FIG. First, the facility / specific area name 26 in the sound data information table 25 is displayed on the screen of the display device 18 in a list format. The user uses the operation unit 23 to select and determine a facility or a specific area from the list (step S11). Then, the current setting value of the sound data name 27 related to the determined facility / specific area name 26 is read from the sound data information table 25 and displayed on the screen of the display device 18. When changing the current setting value, the sound data name 27 is edited using the operation unit 23 (step S12). At this time, if necessary, another registered sound data name 27 is displayed in a list form, and the sound data name 27
Can also be selected. Selected sound data name 27
Is reproduced once (step S13), and it is left to the user to determine whether or not to determine (step S14). If it is to be changed, the process returns to step S12, and again selects the sound data name 27 from the list. If there is no problem, the selected sound data name 27 is stored in the sound data information table 25 (step S15), and the subroutine processing of SUB3 ends.

Next, the new sound data input processing SUB shown in FIG.
Referring to FIG. 7, a procedure for setting the sound data for which the system has not been registered by the user at the facility position where the system has not been registered, which is processing equivalent to 2, will be described. As a condition to be set, the location of the "XYZ store" is 35 degrees north latitude 0 minute 0 minute 0
Second, 135 degrees 0 minutes 0 seconds east longitude, and the sound data “wind chime sound” to be associated is assumed to be recorded in the third song of the mini disk device with the sound data storage device number 2. First, in the facility / specific area input process (step S21), the host vehicle is stopped in front of the "XYZ store", and the host vehicle position detecting means 1 obtains the latitude information 31 and the longitude information 32 of the current location, Using the section 23, the latitude information 31 and the longitude information 3
Enter 2 directly. At the same time, the facility / specific area name character string is input to determine the sound data reproduction position. After being decided,
The flow shifts to sound data name selection processing (step S22).

In step S22, the sound data storage device number 3 storing the sound data to be registered is first registered in order to register the "wind chime wind" which has not been registered in the system.
3 and the sound data storage position number 34 are input. CPU11
Determines whether sound data exists in the system based on the number (step S23).
As a result of the search, if sound data exists, the sound data is reproduced (step S24). If no sound data exists, the process returns to step S22. It is left to the user to determine whether or not the selected and reproduced sound data is acceptable (step S25). If it is to be changed, the process returns to step S22. If there is no problem, the sound data name input processing (step S2
Go to 6).

In step S26, in addition to the direct input by the user, for example, the name of the music data recorded in the mini-disc medium can be fetched. The sound data name 27 captured from the medium is displayed on the screen of the display device 18 and can be edited by the user. Sound data name 2
When 7 is determined, the set value is stored (step S27).
Move to. In step S27, the input latitude information 31, longitude information 32, sound data storage device number 33, sound data storage position number 34, and sound data name 27 are stored in the sound data information table 25, and then the SUB2 subroutine process is performed. finish.

Next, a procedure for setting a reproduction start condition, a reproduction stop condition and a voice guidance timing, which is a subroutine process corresponding to the reproduction condition setting process SUB4 in FIG. 5, will be described with reference to FIG. First, a reproduction start condition setting process (step S31) is performed. If it is the sound data set in the existing sound data setting process SUB3, the current value of the start condition distance 28 of the sound data name 27 is read from the sound data information table 25 and displayed on the screen. If it is new sound data set in the new sound data input processing SUB2, 0 is displayed on the screen as an initial value of the start condition distance 28. When the user changes the start condition distance 28, the user inputs and determines the start condition distance 28 using the operation unit 23, and proceeds to the reproduction stop condition setting process (step S32).

In step S32, a stop condition distance 29 or a sound data playback time 30 is set as a playback stop condition.
When the setting is made in the existing sound data setting process SUB3, the current setting values of the stop condition distance 29 and the reproduction time 30 are read from the sound data information table 25 and displayed on the screen. If it is new sound data set in the new sound data input process SUB2, 0 is displayed on the screen as an initial value of the stop condition distance 29. When changing the stop condition distance 29, the user inputs and determines the stop condition distance 29 using the operation unit 23. If the sound data reproduction time 30 is set to a value other than 0, it is considered that 0 has been input to the stop condition distance 29. When the stop condition distance 29 is set to a value other than 0, it is considered that 0 has been input for the sound data reproduction time 30. After step S32, the process proceeds to voice guidance timing setting processing (step S33).

In step S33, the timing of voice guidance is set. The voice guidance is to announce the distance such as "200 m diagonally left direction" and the direction viewed from the position of the vehicle, and to provide guidance before sound data reproduction, guidance after, or no guidance. The user selects and determines one of the options. When the setting is made in the existing sound data setting process SUB3, the voice guidance number 35 corresponding to the set sound data is read out from the sound data information table 25, is compared with the guidance number 41 of the voice guidance number table 40, and the operation 42 is displayed on the screen. I do. If it is new sound data set in the new sound data input process SUB2, 0 is set as the initial value of the voice guidance number 35, the corresponding operation is compared with the guidance number 41 of the voice proposal number table 40, and the operation 42 Is displayed on the screen. When changing the voice guidance timing, the user can change the timing using the operation unit 23. At this time, the character string of the operation 42 is displayed on the screen in a list format so that the operation can be selected on the screen, and the user can select and determine. Thereafter, the process proceeds to the set value storing process (step S34). In step 34, the set start condition distance 28, stop condition distance 29,
After the sound data reproduction time 30 and the voice guidance number 35 are stored in the sound data information table 25, the reproduction condition setting process S
End UB4.

Next, the sound data reproduction start / stop processing S in FIG.
The processing of UB1 will be described with reference to FIG. For example, when the relative distance between the own vehicle and the “association” is within 300 m, the voice guidance is performed, and then the “pipe organ” stored in the thirteenth song of the DVD-ROM playback device with the sound data device number 3 Set to play the sound for 5 seconds. First, the system searches for “church” closest to the host vehicle and calculates the relative distance and the angle viewed from the host vehicle position (step S41). Then, the relative distance between the own vehicle and the "church" and the start condition distance are compared (step S42). Relative distance is 3
If it is less than 00 m, the process proceeds to step S43, and if it is more than 300m, the process returns to step S41.

In step S43, the voice guidance number 35 associated with "church" is stored in the sound data information table 2.
5 is read, and if "1", voice guidance is performed (step S44) before sound data reproduction, and sound data reproduction (step S45) is performed. If it is other than "1", the process proceeds to step S45. In step S45, in order to reproduce the sound data, first, from the sound data storage device number 33 and the sound data storage position number 34 associated with "church",
The CPU 11 specifies the sound data to be reproduced, and instructs the sound data reproducing device 20 to reproduce the sound data, and stores the current time on the RAM 19 at the same time. The sound data reproducing device 20 converts the sound data corresponding to the sound data storage position number 34 in the sound data storage medium 21 into, for example, “300
m diagonally right. ", And the process proceeds to the stop condition determination process (step S46).

In step S46, the stop condition distance 29 and the sound data reproduction time 30 in the sound data information table 25 are read, and the sound data stop is examined under the condition where 0 is not stored. In the case of "church", stop condition distance 29
Is 0, the sound data reproduction time 30 is considered. C
The PU 11 calculates the playback time from the current time and the playback start time stored in the RAM 19, and compares the calculated playback time with the sound data playback time 30. If the sound data reproduction time 30 has not yet reached, the process returns to step S45. Sound data playback time 3
If it exceeds 0, that is, in the case of “church”, if it exceeds 5 seconds, the process proceeds to step S47.

When the stop condition distance 29 is set to 100 m in the reproduction stop condition of "church", the relative distance is calculated by searching for "church" closest to the own vehicle. Then, a comparative study of the relative distance between the vehicle and the "church" and the stop condition distance 29 is performed. If the relative distance has not reached the stop condition distance, the process returns to step S45, and if it has exceeded, the process proceeds to step S47. At this time, the target "church" is not limited to the "church" targeted at the time of sound data reproduction, but the target "church" at the time of the sound data reproduction stop condition processing is the target. . As a result, if you are traveling in an area where “church” is concentrated, one
A distance of 000 m will stop the sound of the “pipe organ”.

In step S47, in order to stop the sound data, the CPU 11 issues a reproduction stop command to the sound data reproducing device 20, and shifts to a sound guidance process after reproducing the sound data (step S48). In step S48, the voice guidance number 35 associated with "church" is read from the sound data information table 25, and if "2", voice guidance is performed (step S49), and the process returns to step S41. If it is other than "2", the process returns to step S41.

The present invention is not limited to the above-described embodiment, but may, of course, adopt various other configurations without departing from the gist of the invention.
