  However, the conventional navigation apparatus has the following problems. That is, when the operator performs menu item selection and determination operations continuously in a short time, the same content of voice is output continuously for each of the selection and determination operations. For this reason, there is a problem that the operator is bothered and convenience is impaired.

  Further, depending on the driving state of the vehicle, even if the operator once selects the menu item, the menu item determining operation may or may not be performed immediately. In such a case, when the operator performs a decision operation, since the predetermined time has passed since the audio output of the selected menu item is output, the operator stores the selected menu item for a long time. It is necessary to do so and the burden becomes large. Further, if the menu item selected by the operator is forgotten, the menu item must be set again, which is problematic in terms of operability and convenience.

  Therefore, the present invention provides a vehicle navigation apparatus that can prevent an operator from being bothered and burdened when selecting or determining menu items, and can improve convenience and operability. Is.

  The invention according to claim 1 is a navigation device having means for outputting audio data assigned to a menu item to an audio output device when the menu item is selected or determined. When the menu item determination operation is performed during the voice output to the user or within a predetermined time after the voice output ends (for example, when the determination result in step S18 in the embodiment is YES, the determination result in step S20) Is NO), voice output for the menu item determination operation is prohibited (for example, step S26 in the embodiment).

  According to the present invention, when the selection operation and the determination operation of the menu item are performed in a short time, only the sound for the selection operation of the menu item is output, and the output of the sound of the determination operation with the same content is prohibited. As a result, the operator does not have to listen to the same content multiple times in succession. Therefore, it is possible to prevent the troublesomeness caused by the continuous output of the same sound, and the convenience can be improved.

  According to the first aspect of the present invention, the operator does not have to listen to the same content of the voice a plurality of times continuously, so that the troublesomeness caused by the continuous output of the same content of the voice can be prevented. , Can improve convenience.

Hereinafter, a vehicle navigation apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a vehicle 1 equipped with a vehicle navigation device (navigation device) 7 according to an embodiment of the present invention.
The vehicle 1 includes an operation device 2, a GPS sensor 3, a vehicle speed sensor 4, a speaker 5, a display device 6, and a navigation device 7. The navigation device 7 receives signals from the operation device 2, the GPS sensor 3, and the vehicle speed sensor 4, and outputs them to the speaker 5 and the display device 6 based on these signals.
Hereinafter, each device will be described.

  The operation device 2 is operated by an input operation from an operator (in this case, a vehicle occupant), and can perform an input operation to the display device 6 via the navigation device 7. The menu item selection operation and determination operation are performed by an input operation (PUSH operation) of the controller device 2.

The GPS sensor 3 is a sensor that detects position information of the vehicle 1, and the vehicle speed sensor 4 is a sensor that detects the speed V of the vehicle 1, and each detection value is input to the navigation device 7.
The navigation device 7 includes a database 8, a memory 9, a CPU 10, and a program 11. The database 8 stores various items to be displayed on the display device 6 and data of the item contents. The database 8 stores voice recognition vocabulary corresponding to each data in association with each other.

  In addition, data extracted from the database 8, input data input from the controller device 2, voice identification vocabulary of the data, and the like are appropriately written and deleted in the memory 9. As described above, by temporarily storing the data to be output in the memory 9, it is possible to output a large amount of character data to which the speech recognition vocabulary is added in a short time.

  Further, the CPU 10 operates based on the program 11, extracts data from the database 8 to the memory 9, converts voice recognition vocabulary associated with the extracted data into a voice file, the speaker 5, Output processing to the display device 6 is performed. The program 11 controls the CPU 10 in a plurality of modes (for example, a travel mode and a stop mode) based on input information from the controller device 2, the GPS sensor 3, and the vehicle speed sensor 4.

The display device 6 displays data on the memory 9 and map data output by the CPU 10 on its display screen. When a menu item determining operation is performed, a screen transition corresponding to the menu item is performed.
The speaker 5 outputs sound files such as menu items output by the CPU 10 as sound. In the present embodiment, sound is output from the speaker 5 in response to the menu item selection operation and determination operation, but in certain cases, sound output for the determination operation is prohibited. This will be described with reference to FIGS.

  FIG. 2 is a flowchart showing processing contents for selecting and determining menu items in the embodiment of the present invention. As shown in the figure, in step S12, it is determined whether or not a menu item selection operation has been performed by the operator. If the determination result is YES, the process proceeds to step S14. If the determination result is NO, this determination is performed again. Do. In step S14, the menu item at the selected cursor position is output by voice. Next, in step S16, it is determined whether or not the selected menu item is determined by the operator. If the determination result is YES, the process proceeds to step S18, and if the determination result is NO, this determination is performed again. .

  In step S18, it is determined whether the menu item is being read out when the menu item determination operation is performed. If the determination result is YES, the process proceeds to step S26, and if the determination result is NO, the process proceeds to step S20.

In step S20, it is determined whether a predetermined time has elapsed after reading when the menu item determination operation is performed. If the determination result is YES, the process proceeds to step S22. If the determination result is NO, the process proceeds to step S26. .
In the case of proceeding to step S22, since a predetermined time has elapsed since the above-described reading process, in order to inform the operator of the menu item that has been determined and operated, voice output of the menu item is started. In step S24, a screen transition corresponding to the determined menu item is performed, and the process is temporarily terminated.

Further, when the process proceeds to step S26, since the predetermined time has not elapsed after the above-described reading process or after completion, the audio output for the determination operation is canceled (prohibited). And it progresses to step S24, the screen transition of a menu item is performed, and a process is once complete | finished.
In this way, it is possible to prevent annoyance caused by continuous output of the same audio content, and improve convenience.

  FIG. 3 is a flowchart showing other processing contents for selecting and determining menu items in the embodiment of the present invention. The processing up to step S14 is the same as that shown in FIG. In step S16, it is determined whether or not a menu item determination operation has been performed. If the determination result is YES, the process proceeds to step S32. If the determination result is NO, this determination is performed again. In step S32, it is determined whether or not a predetermined time Y or more has elapsed since the menu item was read out. If the determination result is YES, the process proceeds to step S34, and if the determination result is NO, the process proceeds to step S24. In step S36, the menu item that has been determined and operated without changing the screen of the menu item is output again by voice, and the determination in step S16 is performed again. At this time, the no-operation time T is once reset. Here, the no-operation time may be measured after the end of recurrence of the menu item in step S34.

If the no-operation time T is shorter than the certain time Y, the screen transition corresponding to the menu item is performed in step S24, and the process is temporarily terminated. At this time, audio output of menu items is prohibited.
In this way, even if the operator forgets the contents of the menu item selected, it is possible to recognize again which menu item is currently selected. In addition, it is possible to prevent troublesomeness caused by the continuous output of the same sound.
