JP 2002-90155 A

  In the navigation device disclosed in Patent Document 1, a user's favorite music can be reproduced only when passing a preset point. However, there is a desire to reproduce the user's favorite music even when the vehicle starts to travel.

The in-vehicle information terminal according to the first aspect of the present invention includes a determination unit that determines whether or not the vehicle has started traveling, a setting management unit that stores music set in advance by the user, and a vehicle that starts traveling by the determination unit. Vehicle control means for reproducing and outputting the music stored by the setting management means for the audio device provided in the vehicle, instead of the sound output so far. is there.
According to a second aspect of the present invention, in the in-vehicle information terminal of the first aspect, when the vehicle control means reproduces and outputs the music stored by the setting management means to the audio device, the display means for displaying the information of the music Is further provided.

  According to the present invention, it is determined whether or not the vehicle has started traveling, and when it is determined that the vehicle has started traveling, the audio device provided in the vehicle is replaced with the sound output so far. Then, the music set and stored in advance by the user is reproduced and output. Since it did in this way, when a vehicle starts driving | running | working, a user's favorite music can be reproduced | regenerated.

  The functional block of the vehicle-mounted information terminal by one Embodiment of this invention is shown in FIG. The in-vehicle information terminal 1 shown in this figure is mounted on a vehicle and used, and when it detects that the vehicle has started running, the operation content set in advance by the user, for example, reproduction of predetermined music or video, air conditioning, Automatically adjusts the temperature of the machine. The in-vehicle information terminal 1 includes a determination unit 2, a setting management unit 3, and a vehicle control unit 4. The setting management unit 3 stores the operation contents to be executed at the start of traveling as user settings.

  The determination unit 2 receives an ACC (accessory) signal, an engine operation signal, and a vehicle speed signal output from the vehicle, and determines whether the vehicle has started running based on the input signal. When it is determined that traveling has started, the user setting recorded in the setting management unit 3 is read and output to the vehicle control unit 4. The vehicle control unit 4 controls the audio, video, or air conditioner according to the contents of the user setting. For example, an audio device provided in a vehicle is caused to reproduce and output a music set in the user setting in place of the sound of a CD or radio broadcast that has been output so far. Note that the contents of the music are stored by the setting management unit 3. Alternatively, the video device is controlled to perform DVD reproduction, or the air conditioner device is controlled to adjust the temperature. In this way, when the vehicle starts traveling, the preset operation content is executed.

  FIG. 2 is a diagram illustrating a specific hardware configuration example of an in-vehicle information terminal described above, which reproduces predetermined music at the start of traveling. The in-vehicle information terminal 1 has a general navigation function for guiding a vehicle to a destination by displaying a recommended route from the departure point to the destination on a map. In addition, the music data is taken in from the music CD and recorded, and the user's favorite music is reproduced and output as necessary. When the vehicle starts to run, the contents are set according to the contents set in the user settings. It is possible to automatically reproduce and output a predetermined music piece.

  The in-vehicle information terminal 1 in FIG. 2 includes a navigation unit 10, a determination control unit 11, a reproduction output unit 12, an HDD 13, a CD / DVD drive 14, and a monitor 15. The reproduction output unit 12 is connected to an audio device 20 for outputting an input audio signal to a speaker (not shown) to output audio.

  The navigation unit 10 detects the current location of the host vehicle based on an arithmetic processing unit 101 configured using a microprocessor, a ROM, a RAM, and the like, and a GPS signal received from a GPS satellite, a detection result of a motion state of the host vehicle, and the like. A current location detection unit 102 and an input operation unit 103 for receiving a request input from the user. Note that a vehicle speed signal from the vehicle is input to the current location detection unit 102, and thus the current location detection unit 102 can detect the motion state of the host vehicle. The vehicle speed signal is also output to the determination control unit 11 via the current position detection unit 102.

  When the destination is set by the user via the input operation unit 103, the current location is detected using the current location detection unit 102, and then the map data recorded in the HDD 13 is read out by the arithmetic processing unit 101 to perform well-known navigation. Process. Thus, the navigation unit 10 obtains a recommended route from the current location to the destination, and displays a map for guiding the vehicle to the destination on the monitor 15, thereby realizing a navigation function in the in-vehicle information terminal 1.

  As described above, the user can request the in-vehicle information terminal 1 to execute the navigation function by operating the input operation unit 103 to set the destination. Further, the user can request the in-vehicle information terminal 1 to execute the music data recording / playback function by operating the input operation unit 103. When a request for the music data recording / playback function is made by the user, the request is notified to the determination control unit 11. As the input operation unit 103, for example, a touch panel integrated with the monitor 15 or a remote controller can be used.

  The determination control unit 11 performs recording / playback processing of music data in response to a request from the user. When recording music data, the HDD 13 and the CD / DVD drive 14 are controlled to read the music data from the music CD set in the CD / DVD drive 14 and write it to the HDD 13. Such a process is called ripping. The written music data is recorded on the HDD 13 in units of music.

  On the other hand, when playing back music data, either the music data recorded on the HDD 13 by the above-described ripping process or the music data recorded on the music CD set in the CD / DVD drive 14 is stored in the music. Can be played in units. The determination control unit 11 controls either the HDD 13 or the CD / DVD drive 14 to read music data, and the music data is converted into an audio signal by the reproduction output unit 12, whereby an audio signal is output to the audio device 2. Thus, music is reproduced and output from the speaker. At this time, the ripping process can be performed in parallel with the reproduction of the music CD.

  Further, the determination control unit 11 executes processing for reproducing predetermined music when the vehicle starts to travel. Specifically, it is determined whether or not the vehicle has started traveling based on the ACC signal, the engine operation signal, and the vehicle speed signal input to the determination control unit 11. As described above, the vehicle speed signal is input via the current position detection unit 102. If it is determined that the vehicle has started running, the music data of the music set in advance in the user settings is extracted from the music data recorded in the HDD 13 and output to the reproduction output unit 12. As a result, an audio signal of a predetermined music is output to the audio device 2 and reproduced and output from the speaker. In this way, by performing operations corresponding to the determination unit 2, the setting management unit 3 and the vehicle control unit 4 in FIG. 1 in the determination control unit 11, it is possible to reproduce and output preset music at the start of vehicle travel. it can.

  Next, an example of the user setting screen is shown in FIG. This screen is displayed on the monitor 15 when performing user settings. Here, as the travel start time switching function, the user can arbitrarily set the content of the operation that is automatically executed when the vehicle travels. In the example of FIG. 3, the “play music” function is selected by checking the check box 21 among the operations “play music”, “play video”, and “switch the air conditioner”. Is shown. In this way, the determination control unit 11 executes the process as described above, and “Song A” displayed in the designation column 22 is automatically reproduced and output when the vehicle starts to travel. Note that the name of the music displayed in the designation field 22 can be arbitrarily designated by the user from the music recorded in the HDD 13 with music data.

  FIGS. 4 and 5 show examples of screens displayed on the monitor 15 before and after the start of traveling of the vehicle when “Song A” is set to be automatically played as described above. . FIG. 4 is a screen showing the vehicle position mark 23 on the road map before the start of traveling. When the vehicle starts running and the vehicle position changes, the vehicle position mark 23 on the road map changes and the screen shown in FIG. 5 is displayed. In this screen, the music name “Music A” and the artist name “Artist X” are displayed on the music playback window 24. In this way, the information of the music whose reproduction output is started at the start of running is displayed.

  In addition, since the above description is an example to the last, it is good also as displaying the information of another content. For example, the album name of the music may be displayed, or the content of information displayed by the user in advance may be set. Moreover, when adjusting the temperature of an air conditioner, you may display the adjustment temperature. In addition to this, various information can be displayed in accordance with the operation content executed at the start of traveling.

  FIG. 6 shows a flowchart when the above-described processing is executed in the in-vehicle information terminal 1 of FIG. This flowchart is executed by the determination control unit 11. In step S1, it is determined whether or not the ACC power supply of the vehicle is ON based on the ACC signal input from the vehicle. If the ACC signal is input, it is determined that the ACC power source is ON, and the process proceeds to the next step S2. In step S2, it is determined whether the engine of the vehicle is started based on the engine operation signal input from the vehicle. If the engine operation signal has been input, it is determined that the engine has started, and the process proceeds to the next step S3.

  In step S3, user settings are read. This user setting is preset in the user setting screen of FIG. In step S4, the vehicle speed change count value is cleared to zero. The vehicle speed change count value is a numerical value recorded for counting the number of times the vehicle speed is increased. When the vehicle speed increases, the value is increased by one in step S6 described later.

  In step S <b> 5, it is determined whether or not the vehicle speed has increased based on a vehicle speed signal input from the vehicle via the current position detection unit 102. When the vehicle speed increases, the process proceeds to the next step S6, the recorded vehicle speed change count value is incremented by 1, and the process proceeds to step S7. On the other hand, if it is determined in step S5 that the vehicle speed has not increased, step S5 is repeated without proceeding to step S6.

  In step S7, it is determined whether or not the vehicle speed change count value is 1. If the vehicle speed change count value is 1, the process proceeds to step S8, and if it is a value other than 1, the process returns to step S5. In step S8, the user setting read in step S3 is confirmed to determine the music to be played. In step S9, the music to be reproduced and output is changed according to the confirmation result of the user setting in step S8. At this time, the music data of the music set in the user settings is extracted from the music data recorded in the HDD 13 and output to the reproduction output unit 12. After executing Step S9, the process returns to Step S5. As described above, the predetermined music set in advance when the vehicle starts to travel is reproduced.

  In the above description, an example of specific processing contents has been described in which music data is recorded in the HDD and predetermined music is reproduced using the recorded music data at the start of traveling. However, predetermined music may be output by automatically performing radio broadcast output or CD playback in step S9 of FIG. Further, the case of controlling the video and the air conditioner as shown in FIG. 1 can also be realized by the flowchart of FIG. Specifically, after determining whether or not the vehicle has started running by executing the processing of steps S1 to S8 in FIG. 6, DVD playback or the like is performed instead of changing the playback music in step S9. Thus, it is possible to output a predetermined image or to control the temperature of the air conditioner device of the vehicle.

According to the embodiment described above, the following operational effects can be obtained.
(1) The determination unit 2 determines whether or not the vehicle has started traveling. If it is determined that the vehicle has started traveling, the vehicle control unit 4 may Instead of the output voice, the music set in advance by the user and stored in the setting management unit 3 is reproduced and output. Specifically, the determination control unit 11 determines whether or not the ACC power source is ON (step S1), determines whether or not the engine is started (step S2), and the vehicle speed has increased. It is determined whether or not the vehicle has started running by determining whether or not the vehicle speed change count value is 1 (step S7). And when it determines with having started driving | running | working, a user setting is confirmed (step S8) and the music reproduced | regenerated and output according to the content is changed (step S9). Since it did in this way, when a vehicle starts driving | running | working, a user's favorite music can be reproduced | regenerated.

(2) When the vehicle control unit 4 reproduces and outputs the music stored by the setting management unit 3 to the audio apparatus, the music information is displayed on the monitor 15 by displaying the music reproduction window 24. It was decided to. Since it did in this way, it can inform a user of the information on the music which started reproduction with the start of running of vehicles.

  In the embodiment described above, it is determined whether or not the vehicle has started running based on the ACC signal, engine operation signal, and vehicle speed signal output from the vehicle. However, it may be determined whether or not the vehicle has started running by other methods. For example, when the present invention is applied to a taxi, it may be determined that the vehicle has started running when a boarding button for starting charging is pressed. In this way, it is possible to output predetermined music or video or adjust the temperature of the air conditioner without the driver being particularly conscious when the passenger is put on.

  In the embodiment described above, an example in which music data is read from a music CD and written to the HDD has been described. However, the present invention is not limited to a general commercial music CD, but a CD-R, MD, DVD, Alternatively, music data can be read from various recording media such as various memory cards. Further, an analog audio signal from a radio or television may be taken in, converted to data by analog / digital conversion, and then written to the HDD.

  The present invention is not limited to the above-described embodiment, and other modes conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention.
