(First embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a navigation device and an information terminal according to an embodiment of the present invention.

  In FIG. 1, the navigation device 1 includes a storage unit 2, an audio unit 3, a navigation unit 4, a position detector 5, a control unit 6, a display unit 7, and an input unit 8. A storage medium 9 is connected to the outside.

  The storage unit 2 stores navigation and audio data such as map data, route data, audio data, and video data. For example, a hard disk is used as the storage unit 2.

  The audio unit 3 reproduces the audio data stored in the storage unit 2 and the audio data of the storage medium 9. As the storage medium 9, a CD, DVD, MD, memory card or the like is used.

  The navigation unit 4 detects the position of the host vehicle and calculates route search / guidance data to the destination by a position detector 5 such as a direction sensor, a vehicle speed sensor, and a GPS.

  The display unit 7 displays the position of the host vehicle, the route to the destination, the reproduction information of the audio data, and the like, and the input unit 8 inputs the selection of the destination and the audio source, the reproduction stop, and the like. A touch panel or a remote control is used as the input unit 8.

  The control unit 6 includes a microprocessor that controls the navigation device 1 as a whole, and controls the storage unit 2, the audio unit 3, and the navigation unit 4 to display on the display unit 7, input processing from the input unit 8, and storage medium. Communication control with 9 is performed.

  Further, in FIG. 1, an information terminal 10 includes a CPU, a ROM, a RAM, a control unit 11 incorporating communication means, a storage device 12 such as a hard disk and a memory, an input device 13 including a keyboard and a pointing device, and a display unit 14 such as a display. , An auxiliary storage device 15 to which an external storage medium 9 is detachably mounted is provided.

  The information terminal 10 is, for example, a personal computer, a PDA, a mobile phone, and the like, and can access an external server through the network 16 such as the Internet by the communication unit of the control unit 11.

  The operation of the navigation device configured as described above will be described below. First, an outline of the navigation operation will be described. Destination data input by the input unit 8 is sent to the navigation unit 4 to generate route search data.

  The vehicle position detected by the position detector 5 is sent to the navigation unit 4 and route guidance data to the destination is created. The created route search / guidance data is displayed on the display unit 7 together with the vehicle position and the map data in the storage unit 2.

  Next, the audio operation will be described. The user selects an audio source and audio data to be reproduced with the input unit 8. Audio sources include CD, DVD, MD, and audio data stored in the storage unit 2.

  The audio unit 3 accesses the selected audio data, outputs the reproduced audio signal to the amplifier, transfers the title and reproduction time of the audio data to the display unit 7 and displays them.

  Next, the control operation in the navigation unit 1 that automatically reproduces the music according to the traveling state such as the traveling position and time of the car will be described with reference to FIGS. FIG. 2 is a diagram showing a specific example of a method for designating a song to be reproduced, and FIG. 3 is a flowchart showing a control operation of the navigation apparatus according to the present invention.

  When the user wants to automatically select a song to be played without operating the audio device while traveling, the user wants to specify in advance the song to be played according to the playback conditions and priority as shown in FIG. As the reproduction condition, the distance and time to the destination, the road on which the vehicle is traveling, the traveling time, traffic congestion information based on information from the VICS, and the like can be set.

  As a method for designating a song, it is possible to designate an album name, a title name, an artist name, a disc number, a track number, and the like based on the song information of the tag and CD text. Data related to the designated condition, priority, and song associated with the condition is stored in the storage unit 2.

  In FIG. 3, while the navigation device 1 is activated, the navigation unit 4 and the position detector 5 always detect the running state such as the vehicle position and the vehicle speed (step S1), and this running state matches the reproduction condition. Is confirmed by the control unit 6 (step S2).

  When the running state matches the reproduction condition, if there are a plurality of matching conditions (step S3), a condition with higher priority is selected (step S4), and the associated audio data is reproduced by the audio unit 3 (step S4). S5). That is, the navigation device 1 automatically switches the music to be played based on the current position, the current time, the distance to the destination, and the time. This operation is continued until a reproduction stop command (step S6) is issued.

  Furthermore, these reproduction conditions can be set using not only the navigation device 1 installed in the vehicle but also the external information terminal 10. The information terminal 10 includes means for searching for a route to the destination, and can set a playback condition based on a distance / time to the destination obtained from the route search data and associate the audio data to be played back. The result is stored in the storage medium 9 via the auxiliary storage device 15.

  The navigation device 1 can execute the control operation shown in FIG. 3 using the data in the storage medium 9. Thereby, the user can set and edit the route search data to the desired destination and the audio data to be reproduced in advance using the information terminal 10 before boarding.

  Thus, according to the present embodiment, using the navigation unit 4 including the position detector 5 and the audio unit 3 that reproduces audio data, the traveling position of the vehicle, the current time, the distance to the destination, Since the audio data to be played back in association with the driving state such as time is set and edited, the audio data related to the vehicle position calculated by the navigation unit 4 and the current time is automatically played back. The music desired by the user is automatically reproduced according to the driving state of the car.

  Furthermore, since the user does not have to perform an audio source switching operation during driving, driving safety is improved. Moreover, since these editing operations can be set in advance outside the vehicle rather than after riding, user convenience is improved.

  Note that the playback conditions and the audio data associated with the playback conditions are stored in the storage unit 2 and can be used any number of times. Further, a plurality of patterns may be stored as reproduction conditions so that the user can select from the plurality of patterns.

  In addition, the navigation device 1 not only reproduces audio data in accordance with the traveling state of the vehicle, but also can display video data and image data such as music video on the display unit 7 in accordance with the traveling state of the vehicle. May be.

  Further, when using the data stored in the storage medium 9, the navigation device 1 may directly access the storage medium 9 inserted in the slot of the navigation device 1 or temporarily store it in the storage unit 2 of the navigation device 1. You may fix it.

  Further, from an external server connected to the network 16 such as the Internet, for example, the latest map data, various facility information such as restaurants and retail stores, fueling facilities and parking lots, video data, audio data, etc. Multimedia information can be downloaded.

  INDUSTRIAL APPLICABILITY The present invention provides a new audio usage form in a vehicle, has an effect of improving user convenience, and is useful for a navigation device with an audio playback function.
