Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car navigation system, a portable navigation system, and a guidance system such as a position guidance simulation by a computer, and is particularly suitable for performing an advertisement for a guidance object. The present invention relates to a position guidance system, an advertisement system, a voice data registration terminal, a position guidance terminal, and a storage medium that are suitable for intuitively grasping the positional relationship between a guidance target object and a current position in an environment where buildings are crowded.

[0002]

2. Description of the Related Art Conventionally, a so-called car navigation system is widely known as a system for guiding a destination to which a passenger goes along with a movement of a vehicle and for guiding a site or a building around the vehicle while the vehicle is running. For example, there has been a vehicle-mounted navigation system disclosed in Japanese Patent Application Laid-Open No. 10-197264.

This car navigation system includes a CD-ROM storing map data, a microprocessor for calculating a current position of the vehicle based on various sensors and reading map data around the current position from the CD-ROM, A display processor that displays a map around the position on the display together with the current position; and a sound generator. The microprocessor has a function of setting an arbitrary point on the map as a registered place in accordance with a user's instruction and a function of detecting a registered place within a predetermined range from the current position. When the registered location is detected by the microprocessor,
Output the alarm sound from the speaker.

[0004] Thus, even while the user is driving a car, the user can recognize the registered place near the current position by voice.

[0005]

By the way, in such an in-vehicle navigation system, if an advertisement accompanying a movement of a vehicle can be made, it is very useful for both a user and an advertisement provider. That is, when the guidance target object is within a predetermined range from the current position of the vehicle, a sound (for example, C
By playing back the M song), the user can understand what type of guidance object is within a predetermined range only by listening to the voice. Since the user can hear the voice regarding the guidance target object, the advertisement effect can be obtained.

[0006] However, the above-mentioned conventional on-vehicle navigation system is configured so that when the registered location to be guided is within a predetermined range from the current position of the vehicle, only a notification is made by an alarm sound. However, the fact that the guidance target object is within the predetermined range can be ascertained at most, and it is difficult to grasp the type of the guidance target object only by hearing the alarm sound.

[0007] Further, the above-mentioned conventional on-vehicle navigation system is configured such that when the registered place to be guided is within a predetermined range from the current position of the vehicle, a notification such as an alarm sound is issued only. Therefore, it has been difficult for the user to intuitively grasp the positional relationship between the guidance target and the current position, such as how much distance is from the current position to the guidance target.

Therefore, in order to finally guide the user to the guidance target, it is necessary to notify the route to the guidance target by voice or to indicate the guidance target on the map displayed on the display. . In the former case, the user had to interpret and understand the directions read aloud by voice, and in the latter case, he had to watch the display.

Therefore, a configuration is conceivable in which a sound such as an alarm sound is output with a sound volume corresponding to the distance between the guidance target and the current position. According to such a configuration, when the guidance object is within a predetermined range from the current position of the vehicle, the sound volume increases as the object approaches the guidance object, and conversely, the sound volume increases as the distance from the guidance object increases. Since the volume is reduced, the user can intuitively grasp the positional relationship between the guidance target object and the current position.

However, simply outputting a sound such as an alarm sound with a sound volume corresponding to the distance between the guidance target and the current position requires that the guidance target be located in a suburban area. You will be able to realize the sense of distance in a form close to reality, but if it is a guide object in a city where buildings are overcrowded, for example, for a guide object behind the building, the distance to the guide object You will feel the feeling differently from reality. That is,
In an environment where buildings are crowded, in order to realize a sense of distance to the guidance target in a form close to reality, not only the distance to the guidance target but also the location situation around the guidance target At the same time, it is important to be able to grasp intuitively.

Accordingly, the present invention has been made in view of such unresolved problems of the prior art, and is suitable for performing advertisements for guide objects, and has a structure in which buildings are scattered. The purpose of the present invention is to provide a position guidance system, an advertisement system, a voice data registration terminal, a position guidance terminal, and a storage medium suitable for intuitively grasping the positional relationship between the guidance target object and the current position in an environment where the information is guided. I have.

Next, the configuration of a vehicle-mounted navigation system mounted on the vehicle 100 will be described with reference to FIG. FIG. 5 is a block diagram illustrating a configuration of the vehicle-mounted navigation system mounted on the vehicle 100. As shown in FIG. 5, the in-vehicle navigation system is mounted on a vehicle 100 such as an automobile, and is based on a positioning system 10 for measuring the current position of the vehicle 100 and position data from the positioning system 10.

, The position of the current location is measured, and the measured location of the current location is output as position data.

The voice generation unit 20 performs an audio guidance among the objects in the map data registration DB 52 based on the position data from the positioning system 10, the guidance conditions in the guidance condition storage unit 44, and the registration data in the voice data registration DB 54. A target object extraction unit 22 for extracting an object; a propagation path calculation unit 24 for calculating a propagation path for transmitting a sound wave from the target object extracted by the target object extraction unit 22 to the vehicle 100 via another object; And a voice synthesis unit 26 that synthesizes voice expressed by sound waves that reach the vehicle 100 via the propagation path calculated by the calculation unit 24.

The audio output section 30 has four amplifiers 32a to 32d for amplifying the audio signal from the audio synthesis section 26, and corresponds to each of the amplifiers 32a to 32d.
And four speakers 34a to 34d that convert audio signals output from the audio signals 32 to 32d into audio and output the audio. The speakers 34a to 34d are arranged at different positions in the vehicle 100. Thus, the sound source can be localized depending on the manner of outputting the sound.

The guidance condition setting unit 42 sets the conditions of an object that provides voice guidance as guidance conditions in accordance with the operation of the input device 40 by the user, and stores the set guidance conditions in the guidance condition storage unit 44. It has become.
The guidance conditions include the priority of guidance for the object, the category of the object that the user wants to provide (for example, a convenience store or a restaurant), the type of notification sound, and the distance between the vehicle 100 and the object. There is a guidance range or the like for determining whether to provide guidance. For example, when the user sets the level 4 as the priority, the convenience store as the category of the object, the alarm sound as the type of the notification sound, and 100 [m] as the guidance range in the guidance condition setting unit 42, the vehicle 100 When the user travels on the road and the distance between the convenience store having a priority level of 4 or more and the vehicle 100 becomes 100 [m] or less, a sound source is arranged corresponding to the position of the convenience store and sound is output from the sound source. Assuming this, a sound (alarm sound) from a sound source that will be observed at the current position of the vehicle 100 is generated and output in a pseudo manner.

In the map data registration DB 52, in addition to map data relating to a map, object data relating to objects are registered. The object data is, for example, a map in a predetermined block (for example, 50 [m] × 50

2 based on the object data of
Is registered in the voice data registration DB 54. For example, when setting a new sound source, the user inputs a voice from the voice input device 50, displays a map based on the map data in the map data registration DB 52, and maps an object for which the sound source is desired to be arranged. Select from above. The voice registration unit 56 stores the voice input device 5
When voice data is input from 0 and an object is selected, the object data of the selected object is read from the map data registration DB 52, and the read object data is registered in the voice data correspondence table, and the input voice data is registered in the voice data. Each is registered in the DB 54.

Next, the configuration of the target object extracting section 22 will be described in detail with reference to FIGS. The target object extraction unit 22 is configured to repeatedly execute the target object extraction processing shown in the flowchart of FIG. FIG. 6 is a flowchart showing the target object extraction processing executed by the target object extraction unit 22.

In the target object extraction process, a target object within a predetermined range from the current position of the vehicle 100 is determined based on the position data from the positioning system 10, the guidance conditions in the guidance condition storage unit 44, and the registration data in the voice data registration DB 54. When the target object extracting unit 22 executes the extraction process, the process first proceeds to step S100 as shown in FIG.

In step S100, the positioning system 10
The block to which the vehicle 100 currently belongs is specified on the basis of the position data and the registration data of the map data registration DB 52. The map is divided, for example, as shown in FIG. FIG. 7 is a diagram showing map divisions. As shown in FIG. 7, the map is divided into rectangular blocks. The illustrated map is divided into five blocks in the horizontal direction of the drawing and six blocks in the vertical direction of the drawing, and is composed of a total of 30 blocks. In addition, a plurality of objects are arranged on the map, and a sound source is arranged in correspondence with each object.

In the example of FIG. 7, codes A to E are assigned as horizontal codes in order from the left to blocks in the horizontal direction of the drawing, and codes 1 to 6 are assigned to blocks in the vertical direction of the drawing in order from the top. When each block is specified by a combination of a horizontal code and a vertical code when assigned as a vertical code, an object a is arranged in the block A1, an object b is arranged in the block C1, and an object c is arranged in the block B2. Blocks C2, E2, D3, C4
Objects D, e, f, i, j, and k are stored in D5 and E6.
Are arranged, and objects g and h are arranged in the block B4.

The block to which the vehicle 100 currently belongs is
From the coordinates on the map specified by the position data from the positioning system 10, a corresponding block is searched for to specify the block. In FIG. 7, the white circles indicate the position of the vehicle 100, and when the number 1 is assigned, the vehicle 10
When the block to which 0 belongs is designated as the block D2 by the numbers 2 and 3,
2, C3.

Next, the process proceeds to step S102, where the vehicle 1
A block around 00 is specified. For example, the vehicle 100
Identify eight blocks adjacent to the block to which currently belongs as peripheral blocks. In the example of FIG. 7, at the time when the number 1 is assigned, the blocks C1 to E1, C2, E2, and C3 to E3 surrounded by the boundary line 60 are specified as peripheral blocks. At the time when the number 2 is assigned, the blocks B1 to D1, B2,
Blocks B2 to D2, B3, D3 surrounded by the boundary 64 when D2, B3 to D3 are numbered 3
B4 to D4 are specified as peripheral blocks.

Then, the process shifts to step S104 to read the block data of the object from the audio data correspondence table, and based on the read block data,
The objects in the blocks specified in steps S100 and S102 are extracted. In the example of FIG. 7, at the time when the number 1 is assigned, the objects b, d, e, and f are extracted. At the time when the number 2 is assigned, the objects b, c, d and f are extracted, and when the number 3 is assigned, the objects c, d, f, g, h and i are extracted.

Next, the process proceeds to step S106, where the position data of the object is read from the audio data correspondence table, and the read position data and the positioning system 1 are read.
Based on the position data from 0, the distance between each object extracted in step S104 and the current position of the vehicle 100 is calculated. When the coordinates are rectangular coordinates, the distance is calculated using the x coordinate of the object and the x of the current position of the vehicle 100.
The square of the difference between the coordinates and the vehicle 1
This is performed by squaring the difference between the 00 and the y coordinate of the current position, adding the squared values, and taking the square root of the addition result.

Next, the process proceeds to step S108, and an object within a predetermined range (for example, 80 [m]) is extracted from the vehicle 100 based on the calculated distance. FIG.
In the example of at the time when the number 3 is attached, for example,
A predetermined range is a region indicated by a circle having a radius r around the vehicle 100. Since the object i belongs to the predetermined range, the object i is extracted as a target object.

Then, the process shifts to step S110 to read the category data and the priority data of the object from the voice data correspondence table, and
2, the guidance condition is read out, and based on the read category data and priority order data, objects that match the guidance condition category and have priority or higher are extracted from the objects extracted in step S108.
For example, if the user has set convenience store as the category and level 4 as the priority,
Convenience stores having a priority of level 4 or higher are extracted from the objects extracted in step S108.

Next, the process proceeds to step S112, where the target object extracted in step S110 and the vehicle 10
0 and a predetermined direction of the map (for example,
With respect to (North), an angle formed by a line connecting the target object and the vehicle 100 is calculated, and the process proceeds to step S114.
For example, the moving speed of the vehicle 100 is calculated by differentiating the position data from the positioning system 10 with respect to time, and the process proceeds to step S116.

At step S116, map data registration D
The size data of the object is read from B52, and the read size data, the position data of the object, and the distance, angle and moving speed calculated in steps S112 and S114 are transmitted to the propagation path calculation unit 24 and the speech synthesis unit 26 for each target object. Output and vehicle 1
The current position of 00 is output to the propagation path calculation unit 24 and the speech synthesis unit 26, and a series of processing is ended to return to the original processing.

The target object extracting unit 22 reads the category data and the priority data set as the guidance conditions from the guidance condition storage unit 44, and transmits the read category data and priority data to the voice data registration terminal 200. When the audio data, the category data, the priority data, the block data, and the position data are received, the received audio data is registered in the audio data registration DB 54, and the received category data, priority data, and block data are registered. The position data and the position data are registered in the audio data correspondence table so that the object can be specified. As a result, the sound source is arranged at the position in the virtual space specified by the position data and the like in association with the received audio data,
A new object is registered.

Further, the target object extracting unit 22 changes the priority of the guidance condition storage unit 44 according to the number of objects in a predetermined range of blocks (the block to which the vehicle 100 belongs and the blocks around the block). It has become. Specifically, when the number of objects in a block within a predetermined range becomes equal to or less than a first predetermined number (for example, five), the priority of the guidance condition storage unit 44 is reduced, but the priority is reduced. After that, when the number of objects in the blocks within the predetermined range becomes larger than the first predetermined number, the priority order of the guidance condition storage unit 44 is returned to the original order. On the other hand, when the number of objects in the block in the predetermined range becomes equal to or more than the second predetermined number (for example, 10), the priority of the guidance condition storage unit 44 is increased. When the number of objects in the predetermined range of blocks is smaller than the second predetermined number,
The priority order of the guidance condition storage unit 44 is returned to the original order. When the priority is changed in this way, audio data or the like that meets the guidance conditions is re-downloaded from the audio data registration terminal 200.

Thus, when the number of objects in a predetermined range of blocks decreases, the priority order decreases and the conditions for narrowing down the objects are relaxed. Conversely, when the number of objects in blocks within a predetermined range of blocks increases, the number of objects increases. Since the priorities increase and the conditions for narrowing down the objects are narrowed, it can be expected that an almost constant number of objects will always be guided.

Further, the target object extracting unit 22 measures the number of times of guidance and the guidance time for providing voice guidance for the object, and transmits guidance report information on the measured number of guidance and guidance time to the voice data registration terminal 200. It has become. The transmission of the guidance report information is performed, for example, in response to a request from the voice data registration terminal 200, or is performed at predetermined intervals (for example, every day).

Next, the configuration of the propagation path calculator 24 will be described in detail with reference to FIGS. The propagation path calculation unit 24 is configured to repeatedly execute the propagation path calculation processing shown in the flowchart of FIG. FIG. 8 is a flowchart illustrating a propagation path calculation process performed by the propagation path calculation unit 24.

In the propagation path calculation process, based on the data from the target object extraction unit 22, the propagation path through which the sound wave from the sound source placed in correspondence with the position of the target object propagates to the vehicle 100 via another object. Is calculated by the propagation path calculation unit 24, and as shown in FIG. 9, the process first proceeds to step S200.

In step S200, it is determined whether or not there is a propagation path through which sound waves from a sound source placed in correspondence with the position of the target object directly propagate to the vehicle 100. When judged (Yes)
Shifts to step S202, and calculates the propagation path of the direct wave from the sound source and the arrival time until the sound wave from the sound source reaches the vehicle 100 via the propagation path. The propagation path of the direct wave depends on the coordinates of the target object and the vehicle 100.
, And the actual moving speed of the vehicle 100 with respect to the propagation path. The actual moving speed of the direct wave is calculated by multiplying the moving speed of the vehicle 100 by the cosine of the angle between the incident direction of the propagation path incident on the vehicle 100 and the moving direction of the vehicle 100. The arrival time of the direct wave is calculated by dividing the distance of the propagation path by the speed of sound.

Next, the process proceeds to step S214 to calculate the propagation path and arrival time of the diffracted wave from behind the traveling direction of the vehicle 100. In the example of FIG. 9, the distance of the propagation path among the propagation paths of the diffracted wave is the distance from (x ₃ , y ₃ ) to (x ₄ , y ₈ ) and the distance from (x ₄ , y ₈ ) to (x
₆ , y ₉ ). In addition, the actual moving speed of the propagation path of the diffracted wave is (x ₄ ,
The moving speed of the vehicle 100 is calculated by multiplying the moving speed of the vehicle 100 by the cosine of the angle formed by the line connecting the moving direction of the vehicle 100 and the line connecting (y ₈ ) and (x ₆ , y ₉ ). The arrival time of the diffracted wave is calculated by dividing the distance of the propagation path by the speed of sound.

Next, the flow shifts to step S216 to calculate the propagation path and arrival time of the diffracted wave from above the vehicle 100, and shifts to step S208. In the example of FIG. 9, the distance of the propagation path among the propagation paths of the diffracted wave is
The distance from (x ₁ , y ₁ ) to (x ₅ , y ₆ ) and (x
_5, is calculated by adding the distance from the y ₆₎ to (x _6, y _9). In addition, the substantial moving speed in the propagation path of the diffracted wave is the cosine of the angle formed by the line connecting (x ₅ , y ₆ ) and (x ₆ , y ₉ ) and the moving direction of the vehicle 100. It is calculated by multiplying the speed. The arrival time of the diffracted wave is calculated by dividing the distance of the propagation path by the speed of sound.

Therefore, sound waves from the sound source are
If there is a propagation path that propagates directly to, calculate the propagation path and arrival time of the direct wave, the diffracted wave from the front, the diffracted wave from the back and the reflected wave, otherwise, the diffracted wave from the front, from the back , The reflected wave from above and the reflected wave from above. The diffracted wave and the reflected wave are transmitted to the road 102
Is calculated for objects adjacent to. The reason is that even if the influence of an object that cannot be seen from the vehicle 100 is taken into account, it is difficult for the user to visually recognize the object. Therefore, by considering only the influence of the object that can be seen from the vehicle 100, the user can easily recognize the sound source direction and the distance. Also, the calculation can be simplified.

Next, the configuration of the speech synthesizer 26 will be described in detail with reference to FIG.
This will be described with reference to FIG. FIG. 10 is a diagram illustrating a propagation path of a diffracted wave from above the vehicle 100. The voice synthesis unit 26 reads out the voice data of the target object with reference to the voice data correspondence table,
Direct wave, diffraction from the front based on the propagation path and arrival time of the direct wave, the diffraction wave from the front, the diffraction wave from the back, the diffraction wave and the reflected wave from above, and the read voice data calculated in The voice expressed by the synthesis of the wave, the diffracted wave from behind, the diffracted wave from above, and the reflected wave is synthesized. Specifically, the sound from each propagation path is shifted in phase according to the transmission time, attenuated based on the diffraction coefficient and the reflection coefficient, and further based on the substantial traveling speed of the propagation path, And then combine them.

For example, as shown in FIG. 10, when the sound wave from the target object i is diffracted by the object 104, as the angle β formed by the diffracted wave with respect to the horizontal direction is larger, the sound wave arrives via the propagation path. The high frequency component of the sound wave. This is because a sound wave having a higher frequency is more difficult to diffract. Next, the operation of the above embodiment will be described.

When an advertisement applicant wants to advertise an object such as his / her store, the advertisement applicant accesses the voice data registration terminal 200 using a WWW browser at the advertisement applicant terminals C _{1 to} C _n , and reads the advertisement. Request registration of the desired object. Voice data registration terminal 200
Then, when registration of an object is requested, step S
Through 10, a selection of the input method of the position of the object is requested to the advertisement applicant. Here,
For example, an input method using a map is selected as an input method of the position of the object, and the position of the object is input on the displayed map.

In the voice data registration terminal 200, when a position on the map is input, the corresponding map is displayed on the basis of the input position information via step S14. Here, the advertisement applicant finely adjusts the position of the object on the map and determines the position of the object. When the position of the object is determined, the audio data registration terminal 200 requests the advertisement applicant to select a category and audio data through steps S20 and S22. Here, the advertisement applicant selects an object category from a plurality of categories registered in advance, and selects audio data of a sound source to be arranged corresponding to the object from audio data in the audio data registration DB 244. . For example, if the object is a convenience store, the advertisement applicant selects the convenience store as the category, and selects the CM song of the convenience store as the audio data.

In the voice data registration terminal 200, when the category of the object and the voice data are selected, a simple simulation is executed through steps S24 to S27. Are registered in the audio data registration DB 244 in association with the position data and the like. In the voice data registration terminal 200, when the voice data and the position data are registered in association with each other, the user of the advertisement is requested to select a use form of the present system via step S28. Here, the advertisement applicant selects a use form of the present system from personal use, general use, or use as an advertisement. The advertisement applicant selects, for example, the use as an advertisement as the use mode.

In the voice data registration terminal 200, when the use as an advertisement is input as the use mode, step S3
After 4 to S38, the user registration process is executed if the advertisement applicant is a new user, and the authentication process is executed if the advertisement applicant is not a new user. The advertisement applicant can select the advertisement method and the billing method if the user registration is completed or the user is authenticated in the authentication process.

On the other hand, when the power is turned on to the on-vehicle navigation system, the target object extracting unit 22 and the propagation path calculating unit 24 are activated. The propagation path calculation process is repeatedly executed at predetermined intervals. Of course, the other processing units are also activated when the power is turned on.

In the on-vehicle navigation system, when the user inputs the category of the object for which guidance is desired and the priority of guidance for the object from the input device 40, the guidance condition setting unit 42 indicates the input category and priority. It is stored in the condition storage unit 44. During or before traveling of the vehicle 100, the target object extracting unit 22 reads the category data and the priority data from the guidance condition storage unit 44, and stores the read category data and priority data in the base station. It is transmitted to voice data registration terminal 200 via 310 and relay station 300.

In the voice data registration terminal 200, the vehicle 10
When the category data and the priority data are received in response to the access from 0, the voice data registration DB 244 is searched based on the received category data and the priority data through steps S50 to S54, and is indicated by the category data. Audio data of the category, which is higher than the priority indicated by the priority data, is searched.

Next, through steps S56 and S58,
The category data, priority data, block data, and position data corresponding to the retrieved audio data are read from the audio data registration DB 244, and the retrieved audio data, and the read category data, priority data, When the block data and the position data are
And the vehicle 100 via the base station 310.

In the car navigation system, upon receiving voice data, category data, priority data, block data, and position data, the target object extracting unit 22 registers the received voice data in the voice data registration DB 54, The received category data, priority data, block data, and position data are registered in the audio data correspondence table so that the object can be specified. Thereby, the sound source is arranged at the position in the virtual space specified by the position data or the like in association with the received audio data, and a new object is registered.

When the vehicle 100 moves by traveling on the roadway 102 in the state where the object is registered in this manner, the positioning system 10 causes the vehicle 100 to move.
The current position of 0 is measured, and the measured current position is output to the target object extracting unit 22 as position data.
In the target object extraction unit 22, when the position data is input, the blocks to which the vehicle 100 currently belongs and the vehicle 100 based on the input position data and the registration data of the map data registration DB 52 are passed through steps S100 to S104. Are identified, and objects in the identified block are extracted based on the block data in the audio data correspondence table.

Then, through steps S106 to S110, the distance between each of the extracted objects and the current position of the vehicle 100 is calculated based on the position data in the voice data correspondence table and the input position data, and the distance is calculated. An object within a predetermined range is extracted from the vehicle 100 based on the distance. Next, the guidance condition storage unit 42
From the extracted object, an object matching the category of the guidance condition is extracted from the extracted objects based on the category data of the audio data correspondence table.

Next, through steps S112 to S116, the distance between the extracted target object and the current position of the vehicle 100 and the angle formed by the line connecting the target object and the vehicle 100 with respect to a predetermined direction of the map are calculated. Then, the moving speed of the vehicle 100 is calculated, and the calculation results are output to the propagation path calculation unit 24 and the voice synthesis unit 26. Next, a case where there is a propagation path through which sound waves from a sound source arranged corresponding to the position of the target object directly propagate to the vehicle 100 will be described.

When the calculation result is input from the target object extraction unit 22, the propagation path calculation unit 24 proceeds to step S
Through 200 to S210, a direct wave, a diffracted wave from the front,
The propagation path and transmission time of the diffracted wave and the reflected wave from behind are calculated, and the calculation results are output to the speech synthesis unit 26. In the voice synthesis unit 26, when the calculation result is input from the propagation path calculation unit 24, the voice data of the target object is read out, and the direct wave calculated by the propagation path calculation unit 24, the diffracted wave from the front, and the Based on the propagation path and arrival time of the diffracted and reflected waves, and the read sound data, the sound expressed by the synthesis of the direct wave, the diffracted wave from the front, the diffracted wave and the reflected wave from the back is synthesized. The synthesized voice is output from the speakers 34a to 34d so that the sound source can be localized.

Next, a case where there is no propagation path through which sound waves from a sound source arranged corresponding to the position of the target object directly propagate to the vehicle 100 will be described. Propagation path calculator 24
Then, when the calculation result is input from the target object extracting unit 22, the propagation path and transmission of the diffracted wave from the front, the diffracted wave from the rear, the diffracted wave and the reflected wave from above via steps S200 and S212 to S216. The time is calculated, and the calculation results are output to the speech synthesis unit 26.

In the speech synthesizer 26, the propagation path calculator 24
When the calculation result is input, the sound data of the target object is read out, and the propagation of the diffracted wave from the front, the diffracted wave from the rear, the diffracted wave and the reflected wave from above calculated by the propagation path calculating unit 24 Based on the route and the arrival time, and the read voice data, the voice expressed by the synthesis of the diffracted wave from the front, the diffracted wave from the rear, the diffracted wave from above, and the reflected wave was synthesized and synthesized. The sound is
The sound sources are output from the speakers 34a to 34d so as to be localized.

Therefore, a user who is a passenger of the vehicle 100 can not only sensibly grasp the distance to the target object, but also sensibly grasp the location situation around the target object. . For example, the sound volume increases as the distance from the object increases, and the sound volume decreases as the distance from the object increases.
If there is another object between 00 and 00, the audio volume is reduced only during that period, and if it passes through it, the audio volume is increased again. Therefore, vehicle 1
By the movement of 00, the user can recognize from the acoustic change whether the target object is behind another object or whether there is a gap between the target object and the target object.

Next, a case where the number of objects in a block within a predetermined range increases or decreases due to the movement of the vehicle 100 will be described. In the in-vehicle navigation system, when the number of objects in a predetermined range of blocks is equal to or smaller than the first predetermined number, the priority order of the guidance condition storage unit 44 is reduced by the target object extraction unit 22. When the priority decreases, voice data or the like matching the guidance conditions is re-downloaded from the voice data registration terminal 200, and the voice data registration D
Registered in B54. Also, after the priority decreases,
When the number of objects in the predetermined range of blocks becomes larger than the first predetermined number, the target object extracting unit 22
Accordingly, the priority order of the guidance condition storage unit 44 returns to the original order. When the priority order returns to the original order, audio data and the like that meet the guidance conditions are re-downloaded from the audio data registration terminal 200 and registered in the audio data registration DB 54.

On the other hand, when the number of objects in the block within the predetermined range becomes equal to or more than the second predetermined number, the priority order of the guidance condition storage unit 44 is increased by the target object extraction unit 22. When the priority order increases, voice data or the like matching the guidance condition is re-downloaded from the voice data registration terminal 200 and registered in the voice data registration DB 54. When the number of objects in the predetermined range of blocks becomes smaller than the second predetermined number after the priority order is increased, the priority order of the guidance condition storage unit 44 is returned to the original order by the target object extracting unit 22. . When the priority order returns to the original order, audio data and the like that meet the guidance conditions are re-downloaded from the audio data registration terminal 200 and registered in the audio data registration DB 54.

[0131] Next, the case of charging the advertisement applicant will be described. In the in-vehicle navigation system, the target object extracting unit 22 measures the number of times of guidance and the guidance time for performing the voice guidance for the object, and transmits guidance report information on the measured number of guidance and the guidance time to the voice data registration terminal 200. Is done.

When the voice report registration terminal 200 receives the guide report information, the received guide report information is used to identify the corresponding object in the voice data registration DB2.
44, and the advertisement applicant is charged based on the guidance report information corresponding to the object registered by the advertisement applicant. As described above, in the present embodiment, the audio data registration terminal 200 has the audio data registration DB 244 for storing audio data, and is provided in the virtual space of the sound source virtually arranged in correspondence with the position of the object. Is input to the voice data registration DB 244 while the voice data is registered in the voice data registration DB 244 in association with the input position data and the like.
Forty-four voice data and the corresponding position data are transmitted to the on-vehicle navigation system. When the on-vehicle navigation system receives the voice data and the position data, the vehicular navigation system specifies the received position data and the like. When a sound source is arranged at a position in a virtual space corresponding to the received sound data, and sound is output from the sound source as the vehicle 100 moves, the sound will be observed by the vehicle 100. By generating and outputting a sound from a sound source in a pseudo manner based on the sound data corresponding to the sound source, the position of the object is guided by an acoustic change.

As a result, in the vehicle 100, the position of the target object is guided by voice based on the voice data, so that the user can understand the type of the target object to some extent only by listening to the voice, and For the person, the user can hear the sound related to the advertisement, so that the advertisement effect can be obtained for the object. Therefore, as compared with the related art, the positional relationship between the target object and the vehicle 100 can be intuitively grasped, and the advertisement of the target object can be performed.

Further, in the present embodiment, when the voice data registration terminal 200 receives the priority data in response to the access from the on-vehicle navigation system, it based on the priority data in the voice data registration DB 244,
Voice data and position data or the like having a priority higher than the priority indicated by the received priority data are transmitted to the vehicle-mounted navigation system. The vehicle-mounted navigation system transmits the priority data indicating the set priority to the voice data. When voice data and position data are transmitted to the registration terminal 200 and received, the position of the object is guided based on the received voice data and position data.

Thus, the user can receive guidance for an object relatively in line with the desire only by setting the priority of guidance for the object, and reduces the possibility of guidance for an object for which guidance is not desired. can do. Further, in the present embodiment, when the number of objects in a block in a predetermined range becomes equal to or smaller than the first predetermined number, the in-vehicle navigation system decreases the priority of the guidance condition storage unit 44. ing.

As a result, even if the number of objects in a block within a predetermined range is reduced, the priority is reduced and the conditions for narrowing down the objects are relaxed, so that a substantially constant number of objects is expected to be always guided. it can. Further, in the present embodiment, when the number of objects in a block within a predetermined range becomes larger than the first predetermined number after the priority order is reduced, the in-vehicle navigation system stores the guidance condition storage unit 44. The priority is returned to the original order.

As a result, even if the number of objects in a predetermined range of blocks increases after the priority order is reduced, the priority order returns to the original order and the object narrowing-down condition is tightened again, so that it is always substantially constant. It can be expected that a number of objects will be guided. Further, in the present embodiment, when the number of objects in the predetermined range of blocks is equal to or greater than the second predetermined number, the in-vehicle navigation system increases the priority of the guidance condition storage unit 44. ing.

As a result, even if the number of objects in a predetermined range of blocks increases, the priority order increases and the conditions for narrowing down the objects are narrowed, so that a substantially constant number of objects is expected to be always guided. it can.
Further, in the present embodiment, after the priority order is increased, when the number of objects in the block within the predetermined range becomes smaller than the second predetermined number, the navigation condition of the guidance condition storage unit 44 is determined. The priority is returned to the original order.

As a result, even if the number of objects in a block within a predetermined range decreases after the priority order is increased, the priority order returns to the original order and the conditions for narrowing down the objects are relaxed again. It can be expected that a number of objects will be guided. Furthermore, in the present embodiment, when receiving the category data in response to the access from the vehicle-mounted navigation system, the voice data registration terminal 200 indicates the received category data based on the category data in the voice data registration DB 244. Is transmitted to the vehicle-mounted navigation system. The vehicle-mounted navigation system transmits category data indicating the set category to the voice data registration terminal 200, and transmits the voice data and the position data. When data or the like is received, the position of the object is guided based on the received voice data and position data.

Thus, the user can receive guidance for an object that is relatively in line with the desire only by setting the category of the object, and can reduce the possibility that guidance will be provided for an object for which guidance is not desired. it can. Further, in the present embodiment, the in-vehicle navigation system measures the number of times of guidance and the guidance time for providing voice guidance for the object, and transmits guidance report information on the measured number of guidance and guidance time to the voice data registration terminal 200. When the voice report registration terminal 200 receives the guidance report information, the voice data registration terminal 200 converts the received guide report information into an audio data registration DB 244 such that an object corresponding thereto can be specified.
, And charging for the advertisement applicant is performed based on the guidance report information corresponding to the object registered by the advertisement applicant.

[0141] Thus, the advertisement provider is charged according to the number of times or time when the advertisement is actually given to the user, so that a relatively rational charging method can be provided. . Further, in the present embodiment, a sound source is virtually arranged corresponding to the position of the target object, and a sound wave from the sound source propagates to vehicle 100 via another object based on position data from positioning system 10. To determine the propagation path of the vehicle 100 via the propagation path.
Is artificially generated as a sound expressed by a combination of a direct wave, a diffracted wave, and a reflected wave that reaches the sound source, and the generated sound is output from a plurality of speakers 34a to 34d so that a sound source can be localized.

As a result, in outputting the sound,
Since the synthesis of the direct wave, the diffracted wave, and the reflected wave is considered, the positional relationship between the target object and the vehicle 100 can be intuitively grasped together with the location situation around the target object. Therefore, as compared with the related art, the positional relationship between the target object and the vehicle 100 can be intuitively grasped in an environment where the objects are scattered.

Further, in the present embodiment, based on the moving speed detected by the target object extracting unit 22, the sound expressed by the combination of the direct wave, the diffracted wave and the reflected wave is adjusted according to the moving speed of the vehicle 100. It has a Doppler effect. Thus, when the vehicle 100 moves, the positional relationship between the target object and the vehicle 100 can be more intuitively grasped together with the location situation around the target object. Therefore, the target object and the vehicle 1 in an environment where the objects are crowded
The positional relationship with 00 can be more intuitively grasped.

Further, in the present embodiment, the category data of the object is read out from the audio data correspondence table, the notification condition is read out from the notification condition storage section 42, and based on the read out category data, the object extracted from the object extracted in step S108 From now, objects that match the category of the notification condition are extracted. Thereby, a sound is output for an object for which the user wants to be notified, so that guidance relatively in accordance with the user's wish can be realized.

In the above embodiment, the object corresponds to the guide object according to claims 1 to 8, 11, 15 to 20, or the object according to claims 12 to 14, and the block data and the position data are Item 1,
It corresponds to the sound source position information described in 2, 3, 11, 16 to 20. The category data corresponds to the category information described in claim 11, and the priority order data is defined in claim 3.
It corresponds to the described priority information.

In the above embodiment, the on-vehicle navigation system corresponds to the position guidance terminal described in claims 2 to 8, 11 to 13, 15, 17 to 19, and the voice data registration DB 244 corresponds to claim 1. 2,
It corresponds to the storage means described in 3, 11, 15, 17 or 19. Steps S10 to S18, S40, S
42 corresponds to the input means described in claims 1, 2, 17 or 19, and step S27 corresponds to claims 1, 2, 3, 1
Steps S54 to S58 correspond to the registration means described in claim 1, 17, or 19, and steps S54 to S58 are described in claims 2, 3, 11, 17 or 1.
9 corresponds to the transmitting means.

In the above embodiment, the guidance condition setting section 42 corresponds to the priority setting means according to claim 3 or 4, or the category setting means according to claim 11, and the guidance condition storage section 44 includes: The current position of the vehicle 100 corresponds to the observation point described in claims 1, 2, 4, 12, 13, 14, 18, or 20.

In the above-described embodiment, the on-vehicle navigation system is configured to change the priority of the guidance condition setting unit 42 in accordance with the number of objects in a predetermined range of blocks. The present invention is not limited to this, and the size of the blocks in the predetermined range may be changed according to the number of objects in the blocks in the predetermined range.

More specifically, when the number of objects in the block in the predetermined range becomes equal to or less than the third predetermined value, the number or size of the block in the predetermined range is enlarged and the object in the block in the predetermined range is expanded. When the number becomes equal to or more than the fourth predetermined number, the number or size of the blocks in the predetermined range is reduced. Thereby, even if the number of objects in the blocks in the predetermined range is reduced, the number or size of the blocks in the predetermined range is enlarged, so that it is expected that a substantially constant number of objects are always guided,
Since the set priority does not increase or decrease, it is possible to reduce the possibility that guidance is performed for an object for which the user does not want to provide guidance.

Even if the number of objects in the predetermined range of blocks increases, the number or size of the blocks in the predetermined range is reduced, so that a substantially constant number of objects can always be expected to be guided. Since the set priority does not increase or decrease, it is possible to reduce the possibility that guidance is performed for an object for which the user does not want to provide guidance.

Further, in the above embodiment, based on the moving speed detected by the target object extracting unit 22,
Although the Doppler effect according to the moving speed of the vehicle 100 is given to the voice expressed by the combination of the direct wave, the diffracted wave, and the reflected wave, the speed is independent of the moving speed of the vehicle 100. May be configured to provide a Doppler effect according to the above. For example, the distance between the target object and the current position of the vehicle 100 is predetermined (for example, 10
[m]) When the following condition is satisfied, the Doppler effect according to the speed irrelevant to the moving speed of the vehicle 100 is given to the voice expressed by the combination of the direct wave, the diffracted wave and the reflected wave.

As a result, the target object and the vehicle 10
When the distance from the current position of 0 is equal to or less than a predetermined value, the output sound is emphasized more than the sound felt at the actual moving speed and the Doppler effect is applied, so that the user can incline that the target object is close. . Further, in the above-described embodiment, four propagation paths are specified, and a sound expressed by combining a direct wave, a diffracted wave, or a reflected wave that reaches vehicle 100 via each propagation path is generated. However, the present invention is not limited to this, and a configuration may be adopted in which a greater number of propagation paths are specified, and a sound expressed by a combination of a direct wave, a diffracted wave, or a reflected wave that reaches the vehicle 100 via each propagation path is generated. . This makes it possible to more intuitively grasp the positional relationship between the target object and the vehicle 100 in an environment where the objects are crowded.

Furthermore, in the above embodiment, the sound wave from the sound source propagates to the vehicle 100 via another object in consideration of the diffracted wave and the reflected wave. However, the present invention is not limited to this. Alternatively, an interference wave generated by combining any of the reflected waves may be considered. Furthermore, in the above-described embodiment, the sound wave from the sound source propagates to the vehicle 100 via another object in consideration of the diffracted wave and the reflected wave. However, the present invention is not limited to this, and the sound wave is diffracted without considering the reflected wave. Only waves may be considered. Even with such a configuration, at least with respect to the direction of the target object viewed from the vehicle 100, the positional relationship between the target object and the vehicle 100 can be intuitively grasped together with the location situation around the target object. .

In the above embodiment, the procedure for calculating the propagation path of the diffracted wave is simply performed in a plane. Specifically, the coordinates of the target object, the coordinates of the other objects, and the vehicle 100 Can be specified by geometrically calculating a tangent connecting the target object to another object and a tangent connecting the current position of the vehicle 100 to another object from the current position of the vehicle. If the object is a polygon, as shown in FIG. 11, among the straight lines connecting each end point of the target object and each end point of the other object, the coordinates of all other straight lines at the contact point with the end point of the object are all one side. The straight line on the side is determined to be tangent. FIG. 11 is a diagram illustrating a process of calculating a diffracted wave when the object is a polygon.

In the example shown in FIG. 11, straight lines l ₁ , l ₂ , and l ₃ can be drawn as straight lines connecting each end point of the object 110 and each end point of the object 112, and the straight line l ₁ has a contact point with the end point of the object 110. (x _10, y ₁₀₎ other linear l ₂ in, l ₃ coordinates located on the lower side of all, an end point of the object 112 contacts (x _11, y ₁₁₎ other in a straight line l _2, l ₃ Since all coordinates are on the lower side, a straight line l
It is determined that ₁ is a tangent connecting the objects 110 and 112.

Further, in the above-described embodiment, the case where the control program stored in the ROM 232 is executed in executing the processes shown in the flowcharts of FIGS. 3 and 4 has been described.
The present invention is not limited to this, and the program may be read from the storage medium storing the program indicating these procedures into the RAM 234 and executed.

Further, in the above-described embodiment, a case has been described in which the processes shown in the flowcharts of FIGS. 6 and 8 are all executed by the target object extracting unit 22 and the propagation path calculating unit 24. Not limited to this, the target object extracting unit 22 and the propagation path calculating unit 24 are configured by connecting a CPU, a ROM, and a RAM by a bus, and the programs are stored in a RAM from a storage medium storing a program indicating these procedures. You may make it read and execute.

Here, the storage medium is a semiconductor storage medium such as a RAM or a ROM, a magnetic storage type storage medium such as an FD or HD, an optical read type storage medium such as a CD, CDV, LD, or DVD; A magnetic storage type / optical readout type storage medium includes any storage medium that can be read by a computer regardless of an electronic, magnetic, optical, or other read method.

Further, in the above embodiment, the on-vehicle navigation system is configured as shown in FIG. 1, but more specifically, it can be configured as shown in FIG. FIG. 12 is a block diagram showing a specific configuration of a vehicle-mounted navigation system to which the present invention is applied. An in-vehicle navigation system includes, in addition to the configuration of FIG. 1, a CPU 70 that controls operations and the entire system based on a control program, as shown in FIG.
