The speech recognition unit 19 recognizes speech input via a microphone (not shown) and outputs the recognition result to the control unit 20. That is, the navigation device 10 is configured to be able to input user instructions via the instruction input unit 17 and the voice recognition unit 19.

  The control unit 20 controls the entire navigation device 10 and is composed of a CPU and its peripheral circuits. The CPU reads various data such as a control program stored in the ROM 30, and the instruction input unit 17 and voice recognition. Control processing of each unit of the navigation device 10 is performed in accordance with a user instruction input through the unit 19. The DRAM 31 is a memory used for the work area of the CPU, and the SRAM 32 is a volatile memory. The DRAM 31 is backed up by a battery or the like while the main power source of the apparatus such as a vehicle accessory power source is off. Memory contents can be retained. The VRAM 33 is a memory in which display data for the display unit 16 is stored.

The information storage unit 21 is a storage unit that stores map data and music data. Specifically, the information storage unit 21 can read out each data stored in a disk-shaped recording medium such as a hard disk device, a CD-ROM, or a DVD-ROM. A reader or the like is applied.
The external recording device control unit 22 records / reads data to / from an external recording medium connected to the navigation device 10 under the control of the control unit 20, and the external recording medium is, for example, a memory stick ( (Registered trademark), memory card, CF card (registered trademark) are applied.
The communication control unit 23 accesses the information center and the Internet through a wireless communication device (for example, a mobile phone) 40 connected to the navigation device 10 under the control of the control unit 20, and performs various operations through the wireless communication network. Receive information.

  When the user is instructed to shift to the navigation mode as the operation mode, the control unit 20 executes a navigation program by the CPU and displays a map or the like on the display unit 16. More specifically, the control unit 20 specifies the current location and traveling direction of the vehicle based on the detection results of the GPS unit 11 and the gyro unit 12, and displays a map around the current location. In addition, when the destination is set, the control unit 20 functions as a route guidance unit that calculates an optimum route to the destination, displays it on the display map, and executes route guidance processing to the destination.

In this navigation mode, when the control unit 20 inputs various types of traffic information from the FM receiving unit 14 or the beacon receiving unit 15, a process for displaying the information (for example, traffic information etc. is displayed in characters, simplified graphics, or a map). Process).
In addition, when the user is instructed to shift to the search mode as the operation mode, the control unit 20 executes a search control program, and the facility (tourist attraction, sightseeing spot, hot spring, A search process for searching a convenience store, a parking lot, etc.) is executed.
The music playback unit 41 includes a speaker device, an amplifier, and the like, and performs playback output of various musical pieces under the control of the control unit 20.

Next, the operation of the embodiment will be described.
FIG. 2 is a processing flowchart of the embodiment.
First, the control unit 20 determines whether or not a navigation target destination is set via the instruction input unit 17 (step S11).
If the navigation target destination is not set in the determination in step S11 (step S11; No), a standby state is entered.

  If it is determined in step S11 that the navigation target destination is set (step S11; Yes), the control unit 20 calculates the estimated arrival time and the remaining time until arrival (step S12).

Subsequently, the control unit 20 selects a music piece to be played back in the remaining time until arrival (step S13), and the music playback unit 41 starts playback.
Subsequently, the control unit 20 determines whether or not the reproduction of the music has ended (step S14).
If it is determined in step S14 that the music has not yet been played back, that is, if it is being played back (step S14; No), the control unit 20 enters a standby state.
In step S14, when the reproduction of the music selected in step S13 is completed (step S14; Yes), the control unit 20 determines whether the host vehicle has arrived at the destination (step S15). .

If it is determined in step S15 that the host vehicle has not arrived at the destination (step S15; No), the control unit 20 subtracts the reproduction time of the specific music selected in step S13 from the arrival time. The music to be played back is selected (step S16), and the music playing unit 41 starts playing. And the control part 20 transfers a process to step S14 again.
If it is determined in step S15 that the host vehicle has arrived at the destination, the control unit 20 ends the process.

  As described above, according to the present embodiment, a song can be automatically selected and played in accordance with the remaining time until arrival, and the user can reduce the operations performed while driving. It is possible to prevent the playback from being finished in the middle of the process or from being finished before arrival.

In the above description, in the processes of steps S13 and S16, the music is selected one by one. However, when a plurality of music is selected and the arrival time to the destination is changed, that is, due to traffic jams. It is also possible to add, delete, or change the music when the arrival is delayed or the arrival is earlier due to a relatively free road.
In the above description, the case where the reproduction of the music piece is completed at the estimated arrival time has been described. However, the reproduction may be completed within a predetermined time before and after the estimated arrival time.

It is a block diagram which shows the structure of the navigation apparatus which concerns on this Embodiment. It is a processing flowchart of an embodiment.
