Abstract

PURPOSE: To reproduce a voice required by a user at a desired part by reproducing the voice which was inputted and has been stored in response to position data when the position data agrees with acquired self position data. CONSTITUTION: When a user arbitrarily inputs a voice message from a voice input part 14, a CPU 9 inputs it into a graphic block 3 via an A/D converter 13 and a key block 4. The CPU 9 reads the latitude and longitude data corresponding to a part on a specified road map from a CD block 5 and stores it in a RAM 8 by making it correspond to the voice message. The CPU 9 searches whether a corresponding voice message exists in the RAM 8 or not when the latitude and longitude data are sent from a GPS block 2. When it has been stored in the RAM 8, the CPU 9 reads the audio message stored corresponding to the latitude and longitude data from the RAM 8 and outputs it from a speaker 17 via a converter 15 and an amplifier 16.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for reproducing voice.

[0002]

2. Description of the Related Art In a conventional navigation device for a vehicle, a map around the position of an automobile equipped with the device is displayed on a monitor, and the position where the automobile is traveling is displayed on the map. Therefore, the user can recognize the current location of the automobile on board by looking at the map displayed on the monitor.

Further, there is a conventional navigation device that automatically reproduces a preset voice. For example, when a vehicle equipped with the device approaches a predetermined location on the travel route, the corresponding sound is automatically reproduced. Some of such automatic voice reproductions generate a guidance message at an intersection or the like during route guidance. There is also a system in which a user inputs a voice and recognizes the voice to operate the navigation device.

[0004]

However, in these conventional navigation devices, the user cannot arbitrarily record and reproduce voice. The location on the map where the voice needs to be reproduced is not limited to the intersection or the like for route guidance as described above, but the location where the voice generation is required and the content of the message are different for each user. For example, when a car equipped with a navigation device approaches a location that requires careful driving, such as a sharp curve, a voice message such as "It will soon be a sharp curve." When a vehicle approaches a location that is to be performed, a voice message such as "Caution warning" is generated, so that the user can output necessary driving precautions to the navigation device at a desired location by voice. I have something I want. Also, for example, when the car passes near the house of the acquaintance of the user,
There is also a request to let users know that they are approaching a geographically recognized location by generating a voice message such as "This is near Mr. ○○ 's house." is there.

In such a case, in the conventional navigation device, since the user cannot arbitrarily input the voice, the voice message required by the user cannot be generated at a desired place. In order for the user to reach the destination quickly, the shortest route is selected by the above route guidance function, and not only the instruction to select the road at the intersection such as the intersection is received, It is preferable that the user can drive while appropriately receiving necessary information by generating a desired voice at a place or the like that is uniquely set by each user.

An object of the present invention is to provide a navigation device capable of reproducing the voice required by the user at a desired location.

[0007]

In order to solve the above problems and achieve the object, the navigation device of the present invention is configured as follows.

(1) The navigation device of the present invention relates to input means for inputting voice, storage means for storing any voice input by the input means in correspondence with position data, and position of the moving body. Self-position data acquisition means for acquiring data, and determination means for determining whether or not the self-position data acquired by the self-position data acquisition means matches the position data stored in the storage means or the correspondence with the position data And a reproduction means for reproducing the sound corresponding to the position data stored in the storage means by the coincidence judgment by the judgment means.

(2) The navigation device of the present invention comprises an input means for inputting a voice, a storage means for storing the voice input by the input means in association with a traveling condition of the moving body, and traveling of the moving body. A traveling condition data acquiring unit that acquires data relating to the condition; a determining unit that determines whether the data acquired by the traveling condition data acquiring unit matches the traveling condition stored in the storage unit; It is composed of a reproduction means for reproducing a voice corresponding to the traveling condition stored in the storage means by the coincidence determination.

(3) The navigation device of the present invention is the device described in (1) or (2) above, and the input means inputs voice from a sound source connected to a predetermined input terminal.

[0011]

As a result of taking the above-mentioned measures (1) to (3), the following effects will occur.

(1) In the navigation device of the present invention, any input voice is stored in correspondence with position data, and when the position data and the acquired self-position data match, the corresponding voice is reproduced. Since the voice required by the user can be stored in association with the desired position on the map, the voice is reproduced when the position of the moving body matches the desired position. As a result, the user can hear the desired voice when the mobile body reaches the position desired by the user, so that the user can appropriately receive the information required when driving the vehicle equipped with the device, You can operate smoothly.

(2) In the navigation device of the present invention, the input voice is stored in association with the traveling condition of the moving body, and when the traveling condition and the acquired data relating to the traveling condition match, the corresponding voice is output. Since the sound is reproduced, the voice required by the user can be stored in association with the desired running condition. Appropriate audio can be generated. This allows the user to pay attention to the traveling speed while driving the automobile, for example, by listening to a voice indicating that when the vehicle is overspeed, and when the traveling distance or traveling time becomes long, for example. , You can pay attention to a proper break by listening to the sound indicating that. By using the device in this way, the operation can be performed more accurately while taking safety into consideration.

(3) In the navigation device of the present invention, since the voice is input from the sound source connected to a predetermined input terminal, the user can make a sound by connecting an audio device or the like to the input terminal. It is possible to input and reproduce voices other than voices, such as music and sound effects. As a result, the user can listen to desired music, sound effects, etc. when the vehicle equipped with the device reaches a position he or she desires or when predetermined traveling conditions are satisfied.

FIG. 4 shows an operation procedure for automatically reproducing the voice message in the navigation device.

When inputting a voice message with the navigation device, first, in step S1, the user operates the cursor key 28 or the like of the remote control unit 20 to display on the road map displayed on the display screen of the monitor block 6. , Specify the location where the voice message needs to be generated with the cursor (for example, near the entrance of a sharp curve). Then, in step S2, the CPU 9 causes the user to select the remote control unit 2
When it is detected from the key block 4 that the RECORD key 37 of 0 is turned on, it is determined in step S3 whether or not recording is possible in the voice recording area in the RAM 8, that is, whether or not the recording area is empty. When it is determined that the user is vacant, the CPU 9 inputs a voice message (for example, "a sharp curve. Hold down the speed.") From the microphone 36, that is, the voice input unit 14, in step S4, and the RECORD key. When it is detected that 37 is turned off, the inputted voice message is converted into digital data by the A / D converter 13 and the graphic block 3 is transmitted via the key block 4 in step S5.
Enter in Then, the CPU 9 reads the latitude and longitude data corresponding to the location on the road map designated in step S1 from the CD block 5, and stores the latitude and longitude data and the voice message in the RAM 8 in association with each other.

If it is determined in step S3 that the RAM 8 has no recording area, the CPU 9 stores in step S6 a message indicating that recording cannot be performed (for example, "cannot record"). ) Is sent to the monitor block 6 via the graphic controller 12. As a result, a message indicating that recording cannot be performed is displayed on the display screen of the monitor block 6. It should be noted that this message that recording cannot be performed can also be output as voice from the speaker 17 via the D / A converter 15 and the amplifier 16.

Next, when reproducing the voice message recorded by the above-mentioned procedure in the navigation device, first, in step S7, when the CPU 9 sends the latitude and longitude data of the current position from the GPS block 2, step S8.
Then, it is searched whether or not the voice message corresponding to the latitude and longitude data is stored in the RAM 8. If it is stored, in step S9, the CPU 9 reads the stored voice message corresponding to the latitude / longitude data (“the curve is sharp. Hold down the speed”).
Read from AM8, D / A converter 15 and amplifier 16
It is output from the speaker 17 via.

If the voice message corresponding to the latitude / longitude data is not stored in the RAM 8 in step S8, the CPU 9 returns to GP in step S7 again.
The latitude and longitude data of the current location are acquired from the S block 2. Such a series of operations of steps S7 to S9
The process is repeated until the CPU 9 detects in step S10 that the power switch 22 is turned off.

According to the above embodiment, the user designates an arbitrary position on the map, a predetermined mark or an intersection displayed on the map, and inputs a voice message. Then, the current location being recognized matches the automatic reproduction condition of the voice message, that is, the latitude and longitude data acquired from the GPS block 2 and any of the latitude and longitude data stored in the RAM 8 match. If it is determined that the corresponding voice message is automatically played. In this way, the navigation device can be used for so-called voice memos.

The following example can be considered as the voice message according to the above embodiment.

[This is near XX's house] (when passing near the house of the acquaintance of the user) • "This corner turns to the right" (when approaching a corner with poor visibility) There are many traffic restrictions "(in places with many speed restrictions, lane restrictions, etc.)-" Be careful "(when you leave your home)-" Do your best because it's about to come "(when approaching your destination) (Variation) ) The navigation device shown in the above embodiment includes the following modifications.

It is also possible to let. For example, the music of "Beast-Ben's No. 9" is played when it passes near the XX house.

(2) The condition for outputting the reproduction command by the CPU 9 is that the corresponding latitude and longitude data is R as in the above embodiment.
It does not have to be stored in the AM8. For example, it is possible to reproduce in association with the traveling speed, the traveling distance, the traveling time, the change of the displayed screen, the operation of a specific key, the designation of an arbitrary position on the map by the input of a pen (not shown), and the like. Examples of voice messages are: "Is it time to take a rest?" (When the continuous running time exceeds a preset time, such as 2 hours) ・ "The speed is too high" (eg 60km / h) Etc., etc. When exceeding the preset speed) etc.

(3) In the above embodiment, the reproduction is automatically performed according to the latitude and longitude data, and the current position is determined by GPS using an artificial satellite as a means for recognizing the current position. The relative position may be obtained by obtaining the traveling locus by the detection means) and the distance sensor (movement amount detection means). This method is called dead reckoning. Further, the position on the map may be obtained by comparing the traveling locus obtained by this dead reckoning and the road shape of the map and determining the passing road. This method is called map matching. Further, this map matching and GPS may be combined.

(4) In the above embodiment, the automatic reproduction is performed according to the latitude and longitude data, but the automatic reproduction can be performed according to the traveling direction data in addition to the latitude and longitude data. That is, when passing a certain point, it is automatically reproduced only when heading in a specific direction.
By doing so, it is effective for information and the like related only to the destination in the traveling direction. Also, in addition to latitude and longitude data, by automatically playing according to time data,
For example, in the case of data whose validity changes depending on the time zone, such as right / left turn information, avoid unnecessary unnecessary automatic playback by automatically playing the data only during the valid time zone. To be

(5) Further, in the above embodiment, the voice message is inputted in correspondence with the latitude and longitude data inputted by the user. ), It is possible to improve the usability by allowing voice messages to be input. When playing this data automatically,
In addition to the method of automatically playing according to the corresponding latitude and longitude data, if you make it automatically play when approaching the vicinity of the corresponding latitude and longitude data, the time lag at the time of voice input will be canceled and played. Further, the usability is improved.

In addition to the above, when a voice message is input during traveling, the voice message is input in correspondence with latitude and longitude data slightly before or after the self position or slightly before and after the own position while traveling. By doing so, the usability will be sufficiently improved simply by automatically reproducing the data according to the latitude and longitude data.
