JP 2001-165676 A

  By the way, when various types of information are displayed on the display during the startup of the system, the display must be visually recognized.

  However, in the case of a vehicle-mounted audio device or a vehicle-mounted navigation device, it is difficult to visually recognize the display when the system is started during operation.

  Further, in the case of a personal computer, it is relatively rare that the display is continuously viewed until the system is started up, such as when another task is completed or the seat is removed until the system is started after the power is turned on. Therefore, even if various types of information are displayed on the display, there is a possibility that they will be missed.

  Therefore, an object of the present invention is to provide an in-vehicle system that can eliminate a user's discomfort due to a waiting time from when the power is turned on until the startup of the system is completed.

  Moreover, this invention makes it a subject to provide the vehicle-mounted system which can validate the time until activation of a system is completed after power activation.

  The present invention has been made in view of the above-mentioned matters. That is, the present invention is an on-vehicle system that is mounted on a vehicle and displays an image and outputs a sound. Detecting and detecting the startup state of the vehicle system, the storage means storing the startup sound data output from the power-on by the means until the startup of the in-vehicle system, the startup sound reading means for reading the startup sound data from the storage means Based on the result, it comprises control means for issuing a start sound data read instruction to the start sound reading means, and output means for outputting the start sound data read by the start sound reading means to the outside of the in-vehicle system. . It is assumed that the startup sound according to the present invention is voice or music and the output means is a speaker.

Thus, by outputting the activation sound during the period from when the power of the in-vehicle system is turned on until the activation of the in-vehicle system is completed, it is possible to eliminate the boredom of the user's waiting time.

  In addition, by outputting a start-up sound, it is not necessary to visually recognize a display that displays a road map or various information provided in an in-vehicle system as in the past, so when the in-vehicle system of the present invention is mounted on a vehicle, The driver's field of view can be secured, and acts such as side-view driving can be actively prevented.

  Furthermore, by outputting the activation sound, it is possible to grasp that the activation of the in-vehicle system is completed even when the user is away from the in-vehicle system of the present invention until the start-up of the in-vehicle system is completed.

  The storage means according to the present invention includes a first area storing default startup sound data and a second area storing music data recorded on the recording medium as startup sound data. The apparatus further comprises an area switching means that is controlled by the control means and switches the area for reading the activation sound data to the first area or the second area.

The startup sound according to the present invention includes a startup sound stored in the first area and a startup sound stored in the second area. The startup sound stored in the first area is the sound data stored in advance in the storage means (default), and the startup sound stored in the second area is CD (Compact Disk), MD (Mini Disk), The music data recorded on a recording medium such as a DVD (Digital Versatile Disk) can be stored in the storage means.

  In this way, since the output start sound can be selectively output, a different start sound can be output each time the in-vehicle system is started. As a result, it is possible to increase the fun and unexpectedness of the time until the in-vehicle system starts up (including the time from when the power to the power source is turned on until the start of the in-vehicle system is completed).

  In addition, the startup sound data stored in the second area can be data of music sound output before the power of the system is turned off. As a result, it is possible to easily remember the music that was being listened to immediately before the system was turned off, and the user can view the continuation of the music.

  Further, the in-vehicle system of the present invention includes a music playback unit that plays back music data recorded on a recording medium, and a trigger that is controlled by the control unit and completes the output of startup sound data. It is also possible to have a configuration further comprising reproduction source switching means for switching between the means.

  For example, when the start-up sound stored in the first area is output and the output of the start-up sound is completed, the control means executes the control of the playback source switching means, and the power supply of the previous system stored in the second area is stored. Play from the continuation of the song that was playing right before the song was cut off.

  As a result, the user can listen to the music from the continuation of the music that was being listened to halfway.

  In addition, when the music data stored in the second area is output from the time when the system is turned on until the start of the system is completed, when the output of the music is completed, immediately before the power is turned off last time. A case of outputting from the music next to the music being played can also be exemplified.

  Thereby, since the user can listen to the music continuously, the user does not listen to the same music repeatedly.

  Further, the present invention has history information storage means for storing history data of music reproduced by the music playback means, and the control means has history data of music being played back by the music playback means in the history information storage means. It is possible to determine whether or not to perform switching control of the area switching unit or the reproduction source switching unit before the system power is turned off based on the determination result.

That is, according to the present invention, it is possible to continue to listen to the startup sound for an arbitrary time from the start of the startup of the system, regardless of the time required for the startup of the system.
Thereby, a user's customizability can be improved.

  Further, the music data reproduced by the music reproducing means according to the present invention is divided into reproduction sources for each type of recording medium, and has priority order setting means for setting priorities for the output of startup sound data to these reproduction sources. It can also be configured. Note that the playback source in the present invention includes the type of playback device (for example, CD, MD, DVD, HDD, etc.) corresponding to the playback media, and startup sound data stored in the first area or the second area. .

  In other words, according to the present invention, when the priority order of the playback source is set by the priority order setting means, the priority of the playback source of the music data being played back is detected by the control means, and the priority order before the system power is turned off. It can be set to play a high playback source.

  As a result, even if it is necessary to temporarily turn off the power to the in-vehicle system during music playback, the priority of the music playback source can be increased to prevent the output of playback sources with lower priority. it can. For example, if the priority of the playback source called CD is set to the highest priority, it is possible to prevent the output of the startup sound stored in the first area having a lower priority than that, and playback immediately before the in-vehicle system is turned off. You can listen to what was in the middle again.

  Further, the present invention may have a configuration having a playback source switching input means for operating the playback source switching input means and the playback source switching means.

  The reproduction source switching input means according to the present invention is preferably provided in an in-vehicle system as a touch panel or a push-type operation switch (button). When the user operates the reproduction source switching input unit, the reproduction source switching unit is switched, and the music can be selectively reproduced instead of the startup sound when the system is activated.

  The present invention also includes a real-time clock that constantly ticks time and a date-time setting unit that sets a date and time for executing the output of the startup sound data, and the control unit includes the date and time of the real-time clock and the set date and time. If it is determined that the two match, the control means may control the area switching means or the reproduction source switching means.

  That is, according to the present invention, when the date and time of the real-time clock coincide with the set date and time, it is possible to output a playback source (music or activation sound) designated by the user when the system is turned on.

  Thereby, for example, it is possible to realize a setting in which the user plays a predetermined music every morning at a predetermined time.

  The present invention also includes an elapsed time data storage means for storing elapsed time data counted from the power-on time counted by the timer means, and a calculation means for calculating average data of elapsed time based on the stored elapsed time data. The control means may be configured to execute switching control of the area switching means or the reproduction source switching means based on the comparison result by the comparison means.

  For example, if the elapsed time data exceeds the average data, the area switching means is controlled to output the startup sound, and if not, the playback source switching means is controlled to output the music from the playback source. .

  This makes it possible to add variations to the startup sound that is output between the time when the system is turned on and the time when the system is started, and the system is starting up. It is possible to prevent the user's interest in the startup sound from being reduced.

  Further, the present invention has history information storage means for storing history data of music reproduced by the music playback means, and the control means has history data of music being played back by the music playback means in the history information storage means. It is possible to determine whether or not to perform switching control of the area switching unit or the reproduction source switching unit before the system power is turned off based on the determination result.

  For example, if the control means determines that there is no history data of the music being played in the history information storage means, the playback source switching means is controlled so that the sound output when the system is started next time becomes a music. To do. Along with this, it is preferable to execute processing for storing the data of the music being reproduced in the history information storage means.

  As a result, the startup sound can be accumulated efficiently and the randomness of the startup sound that is output while the system is running (from the time the system is turned on until the startup of the system is completed) is improved. Can do.

  The present invention also has ripping means for ripping music data, and the control means determines whether or not the ripping means is in the ripping process, and the power to the in-vehicle device is turned off based on the determination result. A configuration may be adopted in which switching control of the area switching unit or the reproduction source switching unit is executed before.

  For example, if the control means determines that the ripping means is in the process of ripping, the control of the playback source switching means is executed to make the sound at the next start-up the music, and if it is determined that the ripping is not in progress, the next time The region switching means is controlled so that the sound output during the period from when the system is turned on until the start of the system is completed is used as the start sound.

  As a result, it is possible to increase the variation of the startup sound output during the period from when the system is turned on to when the startup of the system is completed (during system startup), and to give the user a fresh taste.

  Moreover, it is preferable that the timer means according to the present invention starts counting elapsed time since the power of the in-vehicle system is turned on using vehicle information including a vehicle state as a trigger.

The vehicle information according to the present invention includes information such as the presence / absence of operation of the ignition key provided on the vehicle, the detection result of the seat sensor provided on the seat, ON / OFF of the door lock, vehicle speed, acceleration, rotation speed, etc. It is.

  For example, in response to the operation of the ignition key, it is considered that the power of the system is turned on, and the timer means starts counting the elapsed time from the power-on of the system.

  With such a configuration, a single operation of turning on only the in-vehicle system of the present invention can be omitted.

  Further, the present invention includes trigger setting means for setting vehicle information as a count start trigger of the timer means, and the trigger setting means is displayed on a screen of display means provided in the in-vehicle system device. To do.

  For example, the trigger setting means can be a touch panel provided in an in-vehicle audio device. The user can arbitrarily set the start of the count of the timer means from this touch panel. Thereby, the customizability for the user can be improved.

  The present invention can also be configured to have vehicle information detection means for detecting vehicle information, and to perform switching control of the reproduction source switching means based on the detection result of the vehicle information detection means.

  For example, if the vehicle information is the vehicle speed, the vehicle speed pulse is detected from the vehicle speed sensor, and if the vehicle is determined to be running by the control means, it is output from the time the system is turned on until the system is completely started. The playback source switching means is controlled so that the startup sound to be played is not the startup sound stored in the storage means but the music playback means.

  In this way, by changing the type of sound that is output from the time when the system is turned on until the start of the system is completed based on the vehicle information, it is possible to give variations to the output sound.

  Furthermore, when the in-vehicle system of the present invention is a navigation device or is mounted on the navigation device, the in-vehicle system of the present invention further includes route guidance processing means for guiding the travel route of the vehicle. Then, when the control means according to the present invention detects that the route guidance processing means is in the route guidance processing, the control means executes the switching control of the area switching means or the reproduction source switching means before the power of the system is turned off. This is preferable.

  For example, if the control means of the in-vehicle system of the present invention determines that the route guidance processing means is in the route guidance, the control of the reproduction source switching means is executed, and the music reproduction means is used instead of the startup sound stored in the storage means. To output the music to be played.

  With such a configuration, it is possible to reduce the burden on the cache required for the route guidance process and the music reproduction process, and the process can be performed efficiently.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the vehicle-mounted system which can eliminate the user's discomfort by the waiting time until starting is completed after power activation.

  In addition, the present invention can provide an in-vehicle system that can validate the time from when the power is turned on until the startup is completed.

  Hereinafter, the in-vehicle system of this embodiment will be described in detail with reference to the drawings. Although the in-vehicle system of this embodiment is described as being applied to a car navigation device mounted on a vehicle, the in-vehicle system of the present invention can be applied to various devices other than car audio and in-vehicle type. it can.

(Hardware configuration)
As shown in FIG. 1, the in-vehicle system 1 of the present embodiment has a CPU (Central Processing Unit) 2 that controls the entire system, and an R that temporarily stores information associated with the processing of the CPU 2.
A ROM (Read Only) that stores AM (Random Access Memory) 3 and startup sound data output from the time the system is turned on until the startup of the system is completed, in addition to programs related to startup and various applications. Memory) 4, decompression ASIC (Application Specific Integrated Circuit) 5 that executes decompression processing of data read from ROM 4, HDD (Hard Disc: storage means) 6 that stores various information, and startup sound data from HDD Or a control unit (control means, detection means) 7 for detecting the activation state of the system, a media engine (activation sound reading means) 8 for converting the format of the read activation sound data into an output format, and various recording media Player (music reproduction means) 9 for reproducing music data recorded on (recording medium) 9 A D / A converter 10 that converts digital data transmitted from the controller 7 into analog data, a speaker (output means) 11 that outputs the converted startup sound data to the outside as sound, and a car navigation function GDC (Graphic Display Control) 12 for executing drawing processing;
A display 13 that displays an image (a map, an operation menu, etc.) associated with the navigation process and a UI (User Interface) 14 that assists the user's operation are connected by a local bus 15.

  In addition, the control unit 7 according to the present embodiment detects the activation state of the system (detection unit), and outputs a signal for reading the activation sound data stored in the ROM 4 to the media engine 8 based on the detection result. The startup sound data read from the ROM 4 is decompressed by the decompression ASIC 5. The decompressed startup sound data is converted to an analog signal by the D / A converter 10 and output from the speaker 11.

  With this configuration, the in-vehicle system 1 according to the present embodiment can reproduce the startup sound during the period from when the system is turned on until the startup of the system is completed.

Hereinafter, various processes associated with the functions of the in-vehicle system 1 of the present embodiment will be described.
(Startup sound output)
As shown in FIG. 2, the ROM 4 of the present embodiment includes a first area 4a for storing startup sound data, and a player 9 player 9 (reproducing music data recorded on a recording medium (CD, MD, DVD, etc.)). A second area 4b for storing music data reproduced by the music reproducing means).

  In this embodiment, the activation sound data is a sound stored in the ROM 4 and output via the media engine 8 (hereinafter referred to as an opening sound or a last sound), and the music data is the player 9 It means the data of music played through the.

FIG. 3 shows an output timing chart of the opening sound. The opening sound is output when the power of the system is turned on (when the player 9 and the system (OS) are turned off). The OS of this system takes a long time to start after the system is turned on. That is, the in-vehicle system 1 of the present embodiment outputs a sound (opening sound) at this time, and tries to eliminate the boredom with respect to the waiting time of the user.

  FIG. 4 shows a last sound output timing chart. The output time of the last sound is the same as that of the opening sound, and is when the power of the system is turned on (when the player 9 and the system are activated). However, for the output of the last sound, a process of storing music data output from the player 9 in the second area 4b of the ROM 4 while the player 9 is activated is executed. When the second song is output from the player 9, the data stored in the second area 4b for the first song is overwritten and erased. Therefore, when the second song is output by the player 9, the last sound is output from the beginning of the second song.

Further, the player 9 outputs the third music piece, triggered by the completion of the output of the last sound (second music piece). At this time, in the second area 4b of the ROM 4, the data of the third music piece output from the player 9 is stored.
in this way

  In this way, by outputting the opening sound or the last sound during the period from when the system is turned on to when the activation of the system is completed, it is possible to eliminate the boredom of the user's waiting time.

  Further, since the opening sound or the last sound is output, there is no need to visually recognize the display 13 as in the prior art. Therefore, according to the in-vehicle system of the present embodiment installed in the vehicle, the driver's view is secured. Can actively prevent acts such as driving aside.

(Switching startup sound)
As shown in FIG. 2, the in-vehicle system 1 according to the present embodiment is controlled by the control unit 7, and a sound changeover switch (region changeover unit) that switches the region for reading the activation sound data to the first region or the second region. 16 are provided.

  As described above, when the sound changeover switch 16 is controlled by the control unit 7, the sound output from the time when the system is turned on until the start of the system is completed is either the opening sound or the last sound. Can be switched and output. As a result, a different sound can be output every time from when the system is turned on until the start of the system is completed. As a result, it is possible to enhance the fun and unexpectedness during the system startup (including the period from when the system is turned on until the startup of the system is completed).

  Furthermore, the control unit 7 can also control the sound changeover switch 16 to output the music data that was output before the power of the system was turned off as the last sound.

  This makes it easy for the user to remember the music that was being listened to immediately before the system was shut down, so that the user can listen to the music continuously.

(Switch playback source)
Further, as shown in FIG. 2, the control unit 7 of the present embodiment uses the completion of the output of the startup sound data as a trigger, and a playback source switching unit (playback source switching means) that switches the output data from the opening sound to the last sound. ) 17.

  First, the startup sound stored in the first area is output, and when the output of the startup sound is completed, the control unit 7 executes control to switch the playback source switching unit 17 to the output of the player. Play from the continuation of the song that was playing right before the song was cut off.

  As a result, the user can listen to the music from the continuation of the music that was being listened to halfway.

  In addition, when the control unit 7 outputs the last sound stored in the second area as a sound during system start-up (including the time from when the system is turned on until the start-up of the system is completed), the control unit 7 When the output of the sound is completed, it is also possible to execute control to output from the music next to the music that was being played immediately before the power of the system was turned off.

  As a result, the user can continuously listen to the music from the next music that was being listened to before the previous system was shut down, and thus the user does not listen to the same music repeatedly, thus reducing the redundancy for the user. Can be lowered.

  Note that the playback source switching unit 17 according to the present embodiment may allow the user to arbitrarily set playback source switching. In this case, the playback source switching unit 17 can be operated with a touch panel (playback source switching input means: not shown) provided as the UI 14 of the in-vehicle system 1.

  In this way, by setting the playback source to be switched by the user from the touch panel, the last sound corresponding to the user's preference is selected instead of the opening sound during the period from the system power-on to the completion of the system startup. Can be reproduced automatically, and customization can be improved.

(Switching by timer function)
Further, as shown in FIG. 2, the in-vehicle system 1 of the present embodiment includes a mask setting unit (output time setting unit) 18 for setting a time from when the system is turned on until the start-up sound data is output, And a timer counter (timer means) 19 that counts an elapsed time since the system was turned on. The mask value (set time) set by the user from the mask setting unit 18 and the elapsed time counted by the timer counter are compared by the control unit 7 (comparison means). Then, the control unit 7 controls the sound changeover switch 16 based on the comparison result.

  The user can set the mask value on the screen A shown in FIG. Note that the screen A is displayed on a touch panel provided as the UI 14 of the in-vehicle system 1. On the screen A, a numeric key and an arrow key for setting a mask value and a display unit for displaying the set mask value are displayed. The user inputs a mask value using the numeric keys or arrow keys on screen A.

  In other words, according to the in-vehicle system 1 of the present embodiment, the opening sound or the last sound is output for an arbitrary time from when the power of the system is turned on, regardless of the time required to complete the start-up of the system after the power is turned on. Can be made. Thereby, a user's customizability can be improved.

In the present invention, the vehicle information can also be used as a count start trigger of the timer counter. In this case, the mask setting unit (trigger setting means) 18 is displayed on the screen B shown in FIG. 6, and the user can arbitrarily set the vehicle information to be triggered as with the mask value. In the present embodiment, it is assumed that the mask setting unit 18 is a UI 14 of a touch panel provided in the in-vehicle system 1.

  On the screen B, there are displayed check boxes for vehicle information (ACC-OFF, seat sensor (including ON / OFF of seat belt wearing), door lock) serving as a timer counter count start trigger. The user selects vehicle information that is a trigger to start counting the timer counter from these vehicle information, and checks the check box. For example, when the sheet sensor is checked, when the sheet sensor is turned on, the signal is transmitted to the control unit 7, and the control unit 7 executes a process of starting the count of the timer counter.

(Startup sound priority setting)
Further, the player 9 according to the present embodiment has a plurality of reproduction sources (reproduction drives) such as CD, DVD, MD, and HDD, and the control unit 7 of the present embodiment responds to the output of the opening sound to these reproduction sources. Processing for setting the priority is executed (priority setting means).

  The priority can be set by the user on the screen C shown in FIG. On the screen C, playback source types (CD, DVD, MD, HDD) and check boxes for setting the priority of each playback source are displayed. The user can set the priority for the opening sound for these playback sources by checking the check boxes.

  FIG. 8 shows a processing flow for output control by the output unit when priority is set. For example, as shown in FIG. 7, the priority order of CD, MD, and HDD is set to be higher than that of the opening sound. The control unit 7 determines whether the priority for each playback source is higher or lower than the opening sound (S01). If the control unit 7 determines that the priority order of the CD, MD, and HDD is higher than that of the opening sound, the control unit 7 executes control to switch the sound selector switch 16 to the last sound (S02).

  On the other hand, when the control unit 7 determines in step 01 that the priority order of the DVD is lower than that of the opening sound, control for switching the sound changeover switch 16 to the opening sound is executed (S03). Note that the sound changeover switch 16 is controlled before the power of the system is turned off.

  In this way, even if you have to temporarily turn off the power of this system during music playback, you can increase the priority of each playback source to output startup sound as the last sound instead of the opening sound. Therefore, the user can continue to listen to the music output from the previous playback source when the system is turned on next time. Thereby, the operation of skipping to the previously listened song can be omitted, and the redundancy of the operation can be eliminated.

(Switching using real-time clock)
As shown in FIG. 9, the in-vehicle system 1 of the present embodiment includes a real-time clock 20 that constantly ticks time, and a date setting unit (date setting unit) 21 that sets the date and time when the startup sound data is output. Have. Note that the date and time setting unit 21 can be input by a user from a touch panel (not shown).

As a result, when the control unit 7 determines that the date and time of the real-time clock 20 matches the date and time set by the date and time setting unit 21, the control of the sound changeover switch 16 is executed.

  That is, if the date and time set in the real-time clock 20 and the date and time set by the date and time setting unit 21 match, the startup sound (opening sound or last sound) specified by the user can be output when the system is turned on.

  Accordingly, for example, the user can play a predetermined song every morning at a predetermined time, anniversary, etc., and the custom orientation can be enhanced.

  The control unit 7 not only controls the sound changeover switch 16 but also controls the playback source switching unit 17 when the date and time of the real-time clock 20 matches the date and time set by the date and time setting unit 21. it can. As a result, the user can select the opening sound / last sound output via the media engine 8 or the music output from the player 9, and the user's preference can be enhanced.

(Automatic switching)
Moreover, the vehicle-mounted system 1 of this embodiment can switch the sound changeover switch 16 automatically. As shown in FIG. 10, the in-vehicle system 1 of the present embodiment stores a past timer that stores elapsed time data from when the system is turned on until the start of the system is counted, which is counted by a real-time clock (timer means) 20. A data database (elapsed time data storage unit) 22 and a set time calculation unit (calculation unit) 23 that calculates past timer data (average data of past elapsed time) based on the stored elapsed time data. . The real-time clock may be provided with a clock as timer means separately from the above-described real-time clock.

  Then, the control unit 7 compares the elapsed time data with the past timer data (comparison means), and controls the sound changeover switch 16 based on the comparison result.

  For example, when the elapsed time data exceeds the past timer data, the sound changeover switch 16 is controlled to output the opening sound, and when it does not exceed, the sound changeover switch 16 outputs the last sound. Execute control.

  This allows the user to vary the sound that is output from the time the system is turned on to the completion of the system startup without any special operation. It is possible to prevent the user's interest in the sound (including until the system startup is completed) from decreasing.

The control unit 7 can also control the sound changeover switch 16 by comparing the mask value set by the user with the mask setting unit 18 shown in FIG. 2 and the past timer data.
The control unit 7 can execute not only the control of the sound changeover switch 16 but also the control of the reproduction source changeover unit 17. As a result, the user can select the opening sound / last sound output via the media engine 8 or the music output from the player 9, and the user's preference can be enhanced.

(Switch based on playback history)
The in-vehicle system 1 according to the present embodiment has a reproduction history database (history information storage means: not shown) that stores data of music reproduced by the player 9 in the HD 6. Then, the control unit 7 determines whether or not the data of the music being played is in the playback history database, and based on the determination result, the sound selector switch 16 is switched before the system is powered off. It can also be set as the structure which performs control.

  FIG. 11 shows a processing flow for switching based on the reproduction history. First, the control unit 7 determines whether or not the data of the music being played by the player 9 is in the playback history database (S10). Here, when the control unit 7 determines that there is data of the music being played back, control is performed to switch the sound changeover switch 16 to the output of the opening sound (S11).

  On the other hand, if the control unit 7 determines in step 10 that the data of the music being played is not in the playback history database, control is performed to switch the sound switch 16 to the output of the last sound (S12). Along with these processes, the process of storing the data of the music being reproduced in the second area 4b is also executed.

  As a result, the user can set the startup sound that is output during the startup of the system (including the time from when the system is turned on until the startup of the system is completed) simply by playing the music piece with the player 9. Can do. Further, with such a configuration, it is possible to efficiently accumulate data for the last sound.

(Switching with ripping)
The in-vehicle system 1 of the present embodiment has a ripping unit (ripping processing means: not shown) that converts music data. The control unit 7 determines whether or not the ripping process is in progress, and controls the sound changeover switch 16 before the system is powered off based on the determination result.

  FIG. 12 shows a processing flow for switching control associated with the ripping process. First, the control unit 7 determines whether or not the ripping unit is in the ripping process (S20). If the controller 7 determines that ripping is in progress, the sound changeover switch 16 is controlled so that the sound output at the next power-on of the system is the last sound (S21).

  On the other hand, if it is determined in step 20 that the ripping is not in progress, the control unit 7 controls the sound changeover switch 16 so that the sound output at the next power-on of the system is the opening sound.

  As a result, it is possible to increase the variation of the startup sound during the startup of the system (including the period from when the system is turned on until the startup of the system is completed), and to give the user a fresh taste.

(Switching by vehicle speed pulse)
The in-vehicle system 1 of the present embodiment is based on information such as the presence / absence of operation of an ignition key provided on a vehicle, the detection result of a seat sensor provided on a seat, ON / OFF of a door lock, vehicle speed, acceleration, and rotational speed. A playback source switching unit is included.

  For example, in response to the operation of the ignition key, it is assumed that the power of the system is turned on, and the timer means starts counting the elapsed time since the activation of the system.

  With such a configuration, a single operation of turning on only the in-vehicle system of the present invention can be omitted.

  The present invention can also be configured to have vehicle information detection means for detecting vehicle information, and to perform switching control of the playback source switching unit 17 based on the detection result of the vehicle information detection means.

  Assuming that the vehicle information is the vehicle speed, the vehicle speed pulse is detected from the vehicle speed sensor by the pulse detection circuit 24 as shown in FIG. As shown in FIG. 14, the vehicle speed pulse is detected based on a signal from the real-time clock 20, and when the vehicle speed pulse is detected, a switching signal of the reproduction source switching unit 17 is output.

  In this way, when the control unit 7 determines that the vehicle is running, the control unit 7 determines that the sound output when the power is turned on is not the opening sound or the last sound output via the media engine 8. Then, control of the playback source switching unit 17 is executed to obtain a music played back through the player 9.

  In this way, by changing the type of sound output from when the system is turned on until the start of the system is completed based on the vehicle speed, the output sound can be varied.

(Switching with navigation function)
In addition, when the vehicle route guidance process is being executed, the in-vehicle system 1 of the present embodiment switches the sound changeover switch 16 to set the startup sound to the opening sound or the last sound.

  FIG. 15 shows a switching process flow associated with the navigation function. First, the control unit 7 determines whether or not the system is executing a route guidance process (S30). If it is determined that the route guidance process is being performed, the sound changeover switch 16 is controlled to set the startup sound to the last sound.

  On the other hand, if it is determined in step 30 that route guidance is not being performed, a process of switching the sound changeover switch to 16 is executed in order to set the startup sound as the opening sound. Note that the switching process of the sound selector switch 16 is executed before the power of the system is turned off.

  In this way, depending on whether or not the navigation process is being performed, the type of sound output from the time when the system is turned on until the start of the system is changed, so that the output sound can have variations.

  In addition, with such a configuration, it is possible to reduce the cache burden required for the route guidance process and the music reproduction process, and the process can be performed efficiently.

(Switching with operation switch)
Further, as shown in FIG. 16, the in-vehicle system 1 of the present embodiment includes an operation switch (switch setting unit) 25 for setting the switching of the sound switch 16 by the user. The operation switch 25 is provided in the in-vehicle system 1 as a touch panel or a push-type operation switch (button).

  The in-vehicle system 1 of this embodiment uses the OR circuit output of the operation switch 25 when the user operates the operation switch 25 as a control signal for the sound changeover switch 16.

  With such a configuration, when the user operates the operation switch 25, it is set to select whether the sound output from when the system is turned on until the start of the system is the opening sound or the last sound. can do.
