A speaker 22 corresponding to a part of the sound reproducing means 7 in FIG. 1 is used for sounding sound data. Reference numeral 23 denotes an operation unit corresponding to the operation means 4 in FIG.
[0016]
FIG. 3 is a diagram showing the contents stored in the sound data information table of the in-vehicle 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, a latitude information 31, a longitude information 32, and a sound data storage. It consists of a device number 33, a sound data storage position number 34, and a voice guidance number 35.
[0017]
The facility / specific area name 26 is the name of the facility or specific area associated with the sound data. If the first character of the data is other than an asterisk (*), the facility or specific area related to the character string is the sound data reproduction. If the first character is an asterisk, the facility name or the specific area name including the same character example as the character string after the asterisk is the target for sound data reproduction. For example, in the case of “Airport”, not only “Okayama Airport” but also “Okanan Airfield” and “Air Self-Defense Force Hyakuri Base”. In the case of “* Airport”, “Okayama Airport” is a target facility, but “Okinan Airfield” and “Air Self Defense Force Hyakuri Senri Base” are not.
Thus, the character string set in the facility / specific area name 26 can be associated with a plurality of facilities / specific areas by setting values set in latitude information 31 and longitude information 32 described later to 0, and an asterisk. It is also possible to further limit the facility / specific area by adding to the head of the character string. Thus, for example, by setting the name of a convenience store chain store with an asterisk in the facility / specific area name 26, and setting the jingle that flows in the commercial of this convenience store chain store as sound data, for example, convenience stores in various parts of the country Jingles are automatically played around chain stores.
As the facility / specific area name 26, an expressway interchange or a parking area is used, and sound data can be reproduced even when approaching these. At this time, by adding a process for searching for the shortest interchange from the current location to the parking area, it is possible to avoid the interchange and parking area having different routes from being subjected to sound data reproduction.
[0018]
The sound data name 27 is a character example for identifying when the user selects sound data. When the sound data is newly registered, the user can input a character example using the operation unit. it can. In addition, when a new sound data is registered using a mini disk medium having a data name in the medium such as a mini disk medium, the sound data reproducing apparatus uses the data name stored in the medium. It is also possible for the CPU 11 to register as the sound data name 27 by taking in and passing it to the CPU 11.
Sound data recorded by the user can also be used as sound data. For example, it is possible to edit a cry of a bird recorded with a tape recorder in the forest at home and load the sound stored in a mini-disc medium into the sound data reproducing device 20 for use.
[0019]
The start condition distance 28 is distance data serving as a reference for determining the start of sound data reproduction, and the start condition distance 28 is compared with the straight line distance from the vehicle position calculated by the CPU 11 to the facility or specific area. If is larger, sound data reproduction is started.
[0020]
The stop condition distance 29 is distance data that is one of the criteria for determining whether to stop sound data reproduction, and is compared with the straight line distance from the vehicle position to the facility or specific area calculated by the vehicle position detection means 1. If the stop condition distance 29 is smaller, the sound data reproduction is stopped.
[0021]
The sound data playback time 30 is time data that is one of the criteria for determining whether to stop sound data playback, and is the same as the sound data playback time 30 compared to the playback time calculated from the start of playback by the CPU 11. When it is determined that the sound data is short, the sound data reproduction is stopped. Only when 0 (zero) is designated as the stop condition distance 29, 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 fairly close value, if the vehicle travels for a long time near the threshold distance of the condition, sound data reproduction and stop may be frequently repeated. For this reason, there is a possibility that it cannot be put into practical use, but the occurrence of the same phenomenon can be prevented by setting a stop condition distance 29 that greatly exceeds the start condition distance 28 or setting a sound data reproduction time 30 It is.
[0022]
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 point away from a facility or a specific area, and the user reproduces the sound data at a favorite point. Sometimes remembered.
[0023]
The sound data storage device number 33 is data representing the sound data reproducing device 20 storing the sound data with a unique number in the system, and is added in the order in which the CPU 11 checks the connection state of all devices when the system is started. Is a single digit number.
The sound data storage position number 34 is data in which the relative position of the sound data in the sound data reproducing device 20 is expressed by a unique number in the corresponding sound data reproducing device 20, and the sound data is recorded in the medium. It is a number added in accordance with the order.
[0024]
The voice guidance number 35 is data expressing the condition for voice guidance of the distance and direction of the facility or specific area from the vehicle position, and the number of guidance necessity and the guidance timing can be distinguished by numbers.
[0025]
FIG. 4 is a diagram showing the contents of the voice guidance number in the sound data information table of the in-vehicle navigation device according to the embodiment of the present invention.
In the figure, reference numeral 40 denotes a voice guidance number table, which associates the voice guidance number 35 of the sound data information table 25 with its operation content. 41 is a guide number, and 42 is an operation corresponding to the guide number 41.

[0027]
Next, the operation of the in-vehicle navigation device according to the embodiment of the present invention will be described.
First, an outline of system processing will be described with reference to FIG.
After the system power is turned on, connection check processing (step S1) is performed. In step S1, a connection state check of the sound data reproducing device 20 connected to the system is performed, and a sound data storage device number 33 is added according to the order of the check. The device determined to be abnormal is disconnected from the system, but a number is added so that no contradiction 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 S 2, the CPU 11 once clears the RAM 19 to zero, and then reads the sound data information table 25 and the voice guidance number table 40 from the map information storage device 17 and stores them in the RAM 19. Then, the system startup is completed. Then, the process proceeds to the sound data reproduction start / stop process SUB1 (step S3).
[0028]
In step S3, the map screen is displayed and the user can use it, and the relative distance between the vehicle position and each facility is measured according to the sound data information table 25 stored in the RAM 19, and if necessary. Sound data is played back. Here, using the operation unit 23, the sound data can be changed by a menu operation (step S4). If no menu operation is performed, step S3 remains. After performing Step S4, it is determined whether or not the input is new sound data (Step S5). If it is a new sound data input, a new sound data input process SUB2 (step S6) is performed, and if not, an existing sound data setting process SUB3 (step S7) is performed. After step S6 and step S7, a reproduction condition setting process SUB4 (step S8) for setting sound data reproduction start / stop conditions and voice guidance conditions is performed, and the process proceeds to step S3.
[0029]
Next, 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 the existing sound data setting process SUB3 of FIG. This will be described with reference to FIG.
First, the facility / specific area name 26 in the sound data information table 25 is displayed in a list format on the screen of the display device 18. The user uses the operation unit 23 to select and determine a facility or 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 can be displayed in a list format, and the sound data name 27 can be selected from the list using the operation unit 23. The selected sound data name 27 is reproduced once (step S13), and it is left to the user to decide whether to decide (step S14). If so, the process returns to step S12, and the sound data name 27 is selected again 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 is terminated.
[0030]
Next, with reference to FIG. 7, a procedure for setting the sound data not registered in the system at the facility location where the user is not registered, which is a process corresponding to the new sound data input process SUB2 in FIG. To do.
As a setting condition, the location of “XYZ store” is 35 degrees 0 minutes 0 seconds north latitude, 135 degrees 0 minutes 0 seconds east longitude, and the sound data “wind chime sound” to be associated is sound data storage device number 2 Is recorded on the third song of the mini-disc device.
First, in the facility / specific area input process (step S21), the own vehicle is stopped before the “XYZ store”, and the own vehicle position detection means 1 obtains the latitude information 31 and the longitude information 32 of the current location, Using the unit 23, latitude information 31 and longitude information 32 are directly input. At the same time, the facility / specific area name character string is input to determine the sound data reproduction position. After the determination, the process proceeds to the sound data name selection process (step S22).
[0031]
In step S22, in order to register the “wind chime wind” unregistered in the system, first, the sound data storage device number 33 and the sound data storage location number 34 in which the sound data to be registered are stored are input. The CPU 11 performs a search to determine whether sound data exists in the system based on the number (step S23). If there is sound data as a result of the search, the sound data is reproduced (step S24). If no sound data exists, the process returns to step S22. The decision to determine whether the selected and reproduced sound data is acceptable is left to the user (step S25). If so, the process returns to step S22. If there is no problem, the process proceeds to the sound data name input process (step S26).
[0032]
In step S26, in addition to the direct input by the user, for example, the music data name 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. When the sound data name 27 is determined, the process proceeds to a setting value storing process (step S27).
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 subroutine processing of SUB2 is performed. finish.
[0033]
Next, a procedure for setting a reproduction start condition, a reproduction stop condition, and voice guidance timing, which is a subroutine process corresponding to the reproduction condition setting process SUB4 of FIG. 5, will be described with reference to FIG.
First, a reproduction start condition setting process (step S31) is performed. If it is 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 process SUB2, 0 is displayed on the screen as the initial value of the start condition distance. When changing 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).
[0034]
In step S32, the stop condition distance 29 or the sound data reproduction time 30 is set as the reproduction stop condition. When the existing sound data setting process SUB3 is set, the current set 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 the initial value of the stop condition distance 29. When changing the stop condition distance 29, the user inputs the stop condition distance 29 using the operation unit 23 and determines it. When the sound data playback time 30 is set to a value other than 0, it is considered that 0 is 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 is input in the sound data reproduction time 30. After step S32, the process proceeds to the voice guidance timing setting process (step S33).
[0035]
In step S33, voice guidance timing is set. The voice guidance announces a distance such as “200 m ahead diagonally left” and the direction viewed from the vehicle position. Guidance is given before or after the sound data is reproduced. The user selects and decides one of the options. When set in the existing sound data setting processing SUB3, the voice guide number 35 corresponding to the set sound data is read from the sound data information table 25, and is compared with the guide number 41 of the voice guide number table 40, and the operation 42 is displayed on the screen. To 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 guide number 41 of the voice agreement number table 40, and the operation 42 is performed. Is displayed on the screen. The user can change the voice guidance timing using the operation unit 23. At this time, the character string of the operation 42 is displayed in a list form on the screen so that the operation can be selected on the screen, and the user selects and decides. 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, sound data reproduction time 30, and voice guidance number 35 are stored in the sound data information table 25, and then the reproduction condition setting process SUB4 ends.
[0036]
Next, the sound data reproduction start / stop process SUB1 in FIG. 5 will be described with reference to FIG.
For example, when the relative distance between the vehicle and the “association” is within 300 m, the “pipe organ” stored in the thirteenth song of the DVD-ROM playback device with the sound data device number 3 after voice guidance is provided. Set the sound to play for 5 seconds.
First, the system searches for the “church” closest to the vehicle and calculates the relative distance and the angle viewed from the vehicle position (step S41). Then, the relative distance between the vehicle and the “church” is compared with the start condition distance (step S42). If the relative distance is within 300 m, the process proceeds to step S43, and if it exceeds 300 m, the process returns to step S41.
[0037]
In step S43, the voice guidance number 35 associated with “Church” is read from the sound data information table 25. If “1”, the voice guidance is performed before the sound data is reproduced (step S44) and the sound data is reproduced (step S44). Step S45) is performed. If it is other than “1”, the process proceeds to step S45. In step S45, in order to perform sound data reproduction, first, sound data to be reproduced is specified from the sound data storage device number 33 and the sound data storage position number 34 associated with “church”, and the CPU 11 performs sound data reproduction device. 20 is instructed to reproduce sound data, and at the same time, the current time is stored in the RAM 19. The sound data reproducing device 20 sends sound data corresponding to the sound data storage position number 34 in the sound data storage medium 21 from the speaker 22 as “300 m diagonally rightward”, for example, and determines the stop condition. The process proceeds to processing (step S46).
[0038]
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”, since the stop condition distance 29 is 0, the sound data reproduction time 30 is examined.
The CPU 11 calculates the reproduction time from the current time and the reproduction start time stored in the RAM 19 and compares it with the sound data reproduction time 30. If the sound data reproduction time 30 has not yet been reached, the process returns to step S45. If the sound data reproduction time 30 is exceeded, that is, in the case of “Church”, if it exceeds 5 seconds, the process proceeds to step S47.
[0039]
In addition, when 100 m is specified as the stop condition distance 29 in the regeneration stop condition of “Church”, the “Church” nearest to the subject vehicle is searched to calculate the relative distance. Then, the relative distance between the vehicle and the “church” and the stop condition distance 29 are compared. 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 is the “church” nearest to the vehicle at the time of the sound data reproduction stop condition processing. . As a result, when traveling in a district where “church” is concentrated, the “pipe organ” sound is stopped by leaving 1000 meters away from the district.
[0040]
In step S47, in order to stop the sound data, the CPU 11 issues a playback stop command to the sound data playback device 20, and the process proceeds to a sound guidance process after playback of 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. 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.
[0041]
