  FIG. 3 is a diagram for explaining an example of the data structure of the operation sound information.

  As shown in this figure, the operation sound information 52 has an entry in which a code (operation sound ID) 5122 for identifying an operation sound and sound data 5212 of the operation sound are associated with each other. In the present embodiment, a plurality of audio data 5212 is stored in advance.

  The audio data 5212 may be registered by the user. For example, the arithmetic processing unit 10 can record the user's voice via the microphone 42 and store it as the voice data 5212 in the operation sound information 52. Further, the arithmetic processing unit 10 may read an audio file stored in a portable storage medium and store it as audio data 5212.

The operation sound ID 5312 is information corresponding to the operation sound ID 5211 of the operation sound information 52.

  Here, the vehicle speed (unit: km / h) is used as the setting condition 5311. That is, different operation sounds are associated with each predetermined speed range. By using such setting condition information 53, the operation sound can be changed according to the speed. Further, for example, if the voice data that makes the user feel more dangerous is associated with higher speed, the user can be alerted to driving. As the speed is higher, the volume of the operation sound may be increased.

  Of course, the configuration of the setting condition information 53 is not limited to the above.

  For example, in FIG. 5, the number of operations (unit: times) is used as the setting condition 5311. The number of operations is the number of times the user has operated the navigation device while the vehicle is running, for example, the number of touches on the operation buttons or hard switches displayed on the display device 20. That is, different operation sounds are associated with each range of the predetermined number of operations. By using such setting condition information 53, the operation sound can be changed according to the number of operations. In addition, for example, as the number of operations increases, by associating voice data that makes the user feel dangerous, the user can be alerted to driving. The volume of the operation sound may be increased as the number of operations is increased.

  The setting condition information 53 may be set by the user. For example, the arithmetic processing unit 10 displays an operation screen for accepting setting conditions and operation sound settings on the display device 20, and accepts the setting conditions and designation of operation sounds corresponding to the setting conditions.

  Returning to FIG. 1, the vehicle speed sensor 60, the gyro sensor 62, and the GPS receiver 64 are used to detect the current position (own vehicle position) of the moving body (navigation apparatus 1).

  The vehicle speed sensor 60 is a sensor that outputs vehicle speed data used for calculating the vehicle speed. The gyro sensor 62 is constituted by an optical fiber gyro, a vibration gyro, or the like, and detects an angular velocity due to the rotation of the moving body. The GPS receiver 64 receives a signal from a GPS satellite, and measures the distance between the mobile body and the GPS satellite and the rate of change of the distance with respect to three or more satellites, so that the current position and progress of the mobile body Measure speed.

  The data detected as described above is sent to the arithmetic processing unit 10 and used for navigation processing. Of course, the various sensors may be connected to the navigation device 1 via an in-vehicle LAN or CAN.

  The FM multiplex broadcast receiver 66 receives an FM multiplex broadcast signal transmitted from an FM multiplex broadcast station. FM multiplex broadcasting includes VICS (Vehicle Information Communication System: registered trademark) information, current traffic information, regulatory information, SA / PA (service area / parking area) information, parking lot information, weather information, etc. Information includes text information provided by radio stations.

  The beacon receiving device 68 receives traffic jam information, regulation information, SA / PA information, parking lot information, and the like sent from the beacon.

  Next, the functional configuration of the navigation device 1 will be described with reference to FIG. FIG. 6 is a block diagram illustrating a functional configuration of the navigation device.

  As shown in the figure, the navigation device 1 includes a main control unit 110, a current location calculation unit 120, a route calculation unit 130, a display processing unit 140, an input reception unit 150, an operation sound output unit 160, a parameter acquisition unit 170, an operation sound. A setting unit 180 and a storage unit 190 are included. The storage unit 190 includes map information 51, operation sound information 52, and setting condition information 53.

  The main control unit 110, the current location calculation unit 120, the route calculation unit 130, the display processing unit 140, the input reception unit 150, the operation sound output unit 160, the parameter acquisition unit 170, and the operation sound setting unit 180 are processed by the CPU 11 of the arithmetic processing unit 10. A predetermined program or data is loaded from the storage device 50 or the ROM 13 onto the RAM 12 and executed. The storage unit 190 is constructed by the storage device 50 and the RAM 12.

  The main control unit 110 performs navigation processing (for example, traffic information display, current position display, route display, route guidance, etc.), which is the original basic operation of the navigation device 1.

  Specifically, the main control unit 110 reads out map information around the current location calculated by the current location calculation unit 120 from the storage unit 190. Then, the display processing unit 140 is instructed to display the current location information superimposed on the read map information.

  In addition, when there is route information calculated by the route calculation unit 130, the main control unit 110 instructs the display processing unit 140 to display the route. You may make it display the traffic information acquired via FM multiplex broadcast receiver 66 or beacon receiver 68. FIG. In addition, the main control unit 110 outputs a voice for guiding the user using the speaker 41. Further, processing corresponding to the user operation received via the input receiving unit 150 is performed.

  The present location calculation unit 120 calculates the present location using information output from the vehicle speed sensor 60, the gyro sensor 62, and the GPS receiver 64 at every predetermined interval (for example, every predetermined distance and every predetermined time). The calculated current location information is sent to the main control unit 110, the route calculation unit 130, and the like, and is used for their processing.

  The route calculation unit 130 searches for a recommended route connecting between two designated points (current location, destination).

  Specifically, the route calculation unit 130 first acquires a destination designated by the user via the input reception unit 150. Further, the current location is acquired from the current location calculation unit 120. Further, the map information 51 is read from the storage unit 190. Then, using the Dijkstra method etc., the route connecting the two points (current location and destination) is converted into the link cost (for example, distance and travel time) of the road (link) connecting the predetermined point (node). Search for a route whose total cost on the route is the lowest for other routes.

  In addition, you may make it search for an optimal path | route using the traffic information acquired via FM multiplex broadcast receiver 66 or beacon receiver 68. FIG.

  The display processing unit 140 receives an instruction from another functional unit, generates and outputs a drawing command for causing the display device 20 to display a screen. For example, a map drawing command is generated so as to draw roads, other map components, and marks such as current location, waypoints, destinations, and arrows for recommended routes with a specified scale and drawing method. In addition, a drawing command is generated so as to draw an image such as a menu item for accepting a user instruction or an operation button.

  The input receiving unit 150 receives a user operation input via the input device 30, analyzes the operation content, and controls other functional units so that processing corresponding to the operation content is executed. In addition, from the voice input via the microphone 42, the corresponding operation content is analyzed by voice recognition, and the other functional units are controlled so that the processing corresponding to the operation content is executed.

  For example, when the user performs a touch operation such as a map, a menu item, or an operation button, the input reception unit 150 requests the operation sound output unit 160 to output the set operation sound. Also, for example, when the user requests a search for a recommended route, the input reception unit 150 requests the route calculation unit 130 to display map information, a dialog, a window, and the like for receiving a destination setting. .

  When the operation sound output unit 160 detects a touch operation such as a map, a menu item, or an operation button via the input reception unit 150, the operation sound output unit 160 outputs the operation sound set by the operation sound setting unit 180 via the speaker 41. .

  The parameter acquisition unit 170 acquires a predetermined parameter. The parameter is information for comparison with the setting condition 5311 of the setting condition information 53.

  For example, when the vehicle speed is used as the setting condition (see FIG. 5), the parameter acquisition unit 170 calculates and holds the vehicle speed data using data output from the vehicle speed sensor 60 at predetermined intervals. The calculated vehicle speed data is used by the operation sound setting unit 180.

  Further, for example, when using the number of operations as the setting condition (see FIG. 6), the parameter acquisition unit 170 detects the touch operation via the input reception unit 150, and counts the number of touch operations while the vehicle is traveling, Hold. When the vehicle stops, the number of operations may be reset to zero.

  The operation sound setting unit 180 acquires the parameters held by the parameter acquisition unit 170 at predetermined intervals and compares the parameters with the setting conditions 5311 of each entry in the setting condition information 53. Then, the entry having the matching setting condition 5311 is specified, and the operation sound ID 5312 is acquired.

  Further, the operation sound setting unit 180 specifies an entry having the operation sound ID 5211 that matches the acquired operation sound ID 5312 from the operation sound information 52 and acquires the sound data 5212. Then, the audio data 5212 is set as an operation sound. In this way, the operation sound is changed.

  Next, processing realized by the hardware and functional units described above will be described with reference to FIG.

  FIG. 7 is a flowchart showing a flow of processing for changing the operation sound. This flow is started after the navigation apparatus 1 is activated. This flow is executed at predetermined intervals (for example, every second).

  First, the parameter acquisition unit 170 acquires a predetermined parameter (S100).

  For example, when the vehicle speed is used as the setting condition (see FIG. 5), the parameter acquisition unit 170 calculates the vehicle speed data from the data output from the vehicle speed sensor 60 and holds it. Further, for example, when the number of operations is used as the setting condition (see FIG. 6), the parameter acquisition unit 170 detects the touch operation via the input reception unit 150, counts the number of touch operations, and stores the count. In this case, the number of times is counted regardless of the cycle of this flow.

  Then, the operation sound setting unit 180 determines a setting condition (S110).

  Specifically, the operation sound setting unit 180 acquires the parameter held by the parameter acquisition unit 170 and compares it with the setting condition 5311 of each entry of the setting condition information 53. Then, the entry having the matching setting condition 5311 is specified, and the operation sound ID 5312 is acquired.

  For example, when the vehicle speed is used as the setting condition (see FIG. 5), the operation sound setting unit 180 acquires the vehicle speed from the parameter acquisition unit 170 and compares it with the setting condition 5311 indicating a predetermined speed range of each entry. . Then, an entry having a speed range including the acquired vehicle speed is specified, and the operation sound ID 5312 is acquired.

  In addition, for example, when the number of operations is used as the setting condition (see FIG. 6), the operation sound setting unit 180 acquires the number of operations from the parameter acquisition unit 170, and a setting condition 5311 indicating a predetermined number range of each entry. Make a comparison. Then, an entry having a frequency range including the acquired operation count is specified, and the operation sound ID 5312 is acquired.

  When the operation sound ID 5312 is acquired, the operation sound setting unit 180 compares the acquired operation sound ID 5312 with the operation sound ID of the currently set operation sound, and determines whether or not the operation sound needs to be changed. If it is determined that the set operation sound needs to be changed (YES in S110), the process proceeds to S120. On the other hand, if it is determined that there is no need to change (NO in S110), the process returns to S100.

  When it is determined that the set operation sound needs to be changed (YES in S110), the operation sound setting unit 180 changes the operation sound (S120).

  Specifically, the entry having the operation sound ID 5211 that matches the operation sound ID 5312 of the entry specified in S110 is specified from the operation sound information 52, and the sound data 5212 is acquired. Then, the audio data 5212 is set as an operation sound.

  As described above, the set sound is changed according to a predetermined condition. In addition, the user can be alerted to driving.

  The embodiment of the present invention has been described above. According to the present embodiment, the operation sound can be dynamically changed and various information can be conveyed to the user.

  That is, the operation sound changes according to predetermined conditions such as the vehicle speed and the number of operations. For example, by setting an operation sound that makes humans feel more dangerous as the vehicle speed and the number of operations increase, the user can be alerted to the operation of the navigation device during driving and the driving attention.

  The present invention has been described in connection with exemplary embodiments. Obviously, many alternatives, modifications, and variations will be apparent to practitioners skilled in this art. Accordingly, the above-described embodiments of the present invention are intended to illustrate and not limit the gist and scope of the present invention.

  For example, the following (1) to (7) may be set as the setting conditions.

  (1) Road condition: The setting condition information 53 stores an entry in which a setting condition 5311 indicating the degree of congestion of a road (for example, congestion, congestion, smoothness, etc.) and an operation sound ID 5312 corresponding to the setting condition are stored. To do. The parameter acquisition unit 170 acquires traffic jam information via the FM multiplex broadcast receiving device 66 and the beacon receiving device 68. The operation sound setting unit 180 sets an operation sound according to the setting condition using the acquired parameter. Accordingly, it is possible to prompt the user to pay attention to the operation of the navigation device while driving or to pay attention to driving according to the road conditions.

  (2) Weather: For example, the setting condition information 53 stores an entry in which a setting condition 5311 indicating weather (for example, strong wind, rain, snow, sunny) and an operation sound ID 5312 corresponding to the setting condition are associated with each other. The parameter acquisition unit 170 acquires weather information via the FM multiplex broadcast receiving device 66 and the beacon receiving device 68. The operation sound setting unit 180 sets an operation sound according to the setting condition using the acquired parameter. Thereby, according to the weather, it is possible to prompt the user to pay attention to the operation of the navigation device during driving or to pay attention to driving.

  (3) Date and time: For example, the setting condition information 53 stores an entry in which a setting condition 5311 indicating a time zone (for example, a time zone such as daytime, evening, or night) is associated with an operation sound ID 5312 corresponding to the setting condition. To do. The parameter acquisition unit 170 acquires time information set in the navigation device. The operation sound setting unit 180 sets an operation sound according to the setting condition using the acquired parameter. Thereby, according to the time zone, the user can be alerted to the operation of the navigation device during driving and the driving attention. You may make it change a time slot | zone according to a season.

  (4) Number of curves on the recommended route: For example, the setting condition 5311 indicates in the setting condition information 53 the number of curves (for example, the number of curves on the recommended route existing within a predetermined distance from the current location or the range of the number of curves). And an entry in which the operation sound ID 5312 corresponding to the setting condition is associated. The parameter acquisition unit 170 calculates the number of curves using the current location information and the route information. The operation sound setting unit 180 sets an operation sound according to the setting condition using the acquired parameter. Thereby, according to the number of curves on the recommended route existing within a predetermined distance from the current location, the user can be alerted to the operation of the navigation device during driving and the driving attention.

  (5) Distance to destination: For example, an entry in which the setting condition 5311 indicating the distance from the current position to the destination or the range of the distance and the operation sound ID 5312 corresponding to the setting condition is associated with the setting condition information 53. Store. The parameter acquisition unit 170 calculates the distance using the current location information and the destination information. The operation sound setting unit 180 sets an operation sound according to the setting condition using the acquired parameter. For example, as the distance from the current location to the destination is shortened, if the operation sound that makes the user feel fun is associated, the entertainment property for the user can be enhanced. Further, the user can intuitively recognize the distance to the destination.

  (6) Situation around the current location: For example, in the setting condition information 53, a setting condition 5311 indicating a situation around the current location (for example, a facility such as a ski resort, a zoo, a pool, or a landform such as the sea, a mountain, or a river) An entry in which the operation sound ID 5312 corresponding to the setting condition is associated is stored. The parameter acquisition unit 170 identifies the situation around the current location using the map information. The operation sound setting unit 180 sets an operation sound according to the setting condition using the acquired parameter. For example, if the audio data that allows the user to image the facilities and the terrain are associated with the facilities and the terrain around the current location, entertainment for the user can be improved. Further, the user can intuitively recognize the situation around the current location.

  Of course, the characteristics of the destination (for example, facilities such as ski resorts, zoos, pools, and terrain such as the sea, mountains, and rivers) may be set as the setting conditions. According to the destination facility specified from the map information and the surrounding terrain, if the facility and the terrain are associated with audio data that allows the user to image, entertainment for the user can be improved. The season (for example, spring, summer, autumn, winter) may be set as the setting condition. If the seasons (date and time) are associated with audio data that allows the user to image those seasons, the entertainment characteristics for the user can be improved.

  (7) Remaining amount of fuel: For example, the setting condition information 53 stores an entry in which the setting condition 5311 indicating the remaining gasoline amount or the range of the remaining gasoline amount and the operation sound ID 5312 corresponding to the setting condition are associated with each other. The parameter acquisition unit 170 detects the gasoline remaining amount from a sensor constituted by a liquid level sensor or the like. The operation sound setting unit 180 sets an operation sound according to the setting condition using the acquired parameter. For example, if there is enough gasoline, the user associates audio data that can image a large amount of liquid, and if the remaining amount of gasoline is low, the user can image audio data that can image how the liquid runs out (eg, faint The user can intuitively recognize the remaining amount of gasoline.
