For example, content data (music data and video data) recorded in the music / video data storage unit 20 in the connected mobile terminal device 10 is analyzed, and a content list (content data folder structure, file) is analyzed based on the analysis result. The composition and file attributes (including artist name, album name, song name, etc.) are created, and the song data acquired from the portable terminal device 10 is converted into data in a format that is input to the audio processing unit 58. The mass storage processing unit 102 performs a process of creating a playback menu screen for performing playback of the above, or selecting a playback location or changing a volume by the user during the playback operation.

  When the mobile terminal device 10 operates in the terminal mode, the TM processing unit 104 performs a specific operation corresponding to this (operation of the terminal device operating in the terminal mode). For example, the touch panel 53B is used to perform a process of displaying a screen having the same content when image data indicating the display content of the mobile terminal device 10 is sent, or an operation similar to the operation using the touch panel 13B of the mobile terminal device 10. The TM processing unit 104 performs processing realized in this way.

  The USB function detection unit 110 detects a plurality of functions provided in the mobile terminal device 10 in a predetermined order when the mobile terminal device 10 is connected to the in-vehicle device 50.

  The detection order setting unit 112 sets the detection order when the USB function detection unit 110 detects a plurality of functions (three functions of music player, mass storage, and terminal mode in this embodiment). For example, when different priorities are set for each of a plurality of functions, detection is performed in descending order of priority, or detection is performed in an order corresponding to the contents of the descriptor included in the mobile terminal device 10 as a USB device. And so on.

  The priority order set for each of the plurality of functions may be determined by the user himself / herself using the priority order setting unit 124, in addition to the case where the priority order is determined in advance at the design stage or the like. In addition, the priority of the function executed last when the mobile terminal device 10 was connected last time is set to the highest priority (as a precondition, it is necessary to hold information for specifying the function executed last). , Specific operation start time (when the music player 100, the mass storage processing unit 102, and the TM processing unit 104 are started up, audio sound output and image display corresponding to the terminal mode are actually started for the user. It is conceivable that the priority order is increased in ascending order of time until the time is set.

  The descriptor described above includes function specifying information for specifying a plurality of functions provided in the USB device. For example, the descriptor includes class information corresponding to each of a plurality of functions, the contents of the data string including the class information are examined, and the functions corresponding to the class information are extracted in the order in which the class information is extracted. Detection is performed. This descriptor is built in, for example, the USB interface unit 26 of the mobile terminal device 10.

  Each time a function of the mobile terminal device 10 is detected by the USB function detection unit 110, the function selection screen creation unit 120 displays a function presentation image indicating the presence of this function (for example, the in-vehicle device 50 corresponding to each function). A function selection screen to which a start icon for instructing start of a specific operation executed in step S) is added is created. This function selection screen is displayed on the display unit 55 by the display processing unit 56.

  The function selection processing unit 122 selects one activation icon from one or a plurality of activation icons included in the displayed function selection screen in accordance with a user instruction. The instruction by the user is performed using the operation unit 53A or the touch panel 53B.

  The priority order setting unit 124 sets the priority order of the plurality of functions set by the detection order setting unit 112 in accordance with a user instruction. For example, a priority order setting screen including a list of a plurality of activation icons described above is created and displayed, and the priority order is set by the user specifying the activation icons in descending order of priority. The activation icons included in this priority order setting screen do not correspond to a plurality of functions provided in the mobile terminal device 10 connected at that time, but all correspond to specific operations that can be executed in the in-vehicle device 50. Contains launch icons.

  The USB function detection unit 110 described above is a function detection unit, the function selection screen creation unit 120 is a function selection screen creation unit, the display processing unit 56 and the display unit 55 are display units, and the function selection processing unit 122 is a function selection processing unit. The music player processing unit 100, the mass storage processing unit 102, and the TM processing unit 104 correspond to function execution means, and the priority order setting section 124 corresponds to priority order setting means.

  The in-vehicle system of the present embodiment has such a configuration, and the operation will be described next. FIG. 3 is a flowchart showing an operation procedure of the in-vehicle device 50 until a plurality of functions provided in the mobile terminal device 10 are detected and a specific operation corresponding to each function is started, and the functions are detected in descending order of priority. The operation procedure is shown.

  When the vehicle-mounted device 50 is turned on and starts operating, the USB function detection unit 110 determines whether or not a USB device is connected (step 100). If not connected, a negative determination is made and this determination is repeated. When the mobile terminal device 10 as a USB device is connected, an affirmative determination is made in the determination in step 100.

  Next, the function selection screen creation unit 120 creates a function selection screen, and the display processing unit 56 displays this function selection screen on the display unit (step 102). In addition, immediately after the operation of the in-vehicle device 50 is started, since no function provided in the mobile terminal device 10 is detected, a function selection screen that does not include the activation icon is created and displayed. FIG. 4 is a diagram showing a display example of the function selection screen, and shows a state immediately after the operation of the in-vehicle device 50 is started.

  Next, the function selection processing unit 122 determines whether any activation icon included in the currently displayed function selection screen has been selected (step 104). If the activation icon is not selected, a negative determination is made, and then the USB function detection unit 110 determines whether or not the function detection operation has ended (step 106). If the function detection operation has not ended, a negative determination is made, and the USB function detection unit 110 determines a function to be detected in descending order of priority (step 108). For example, in the present embodiment, among the three functions (music player, mass storage, and terminal mode) provided in the mobile terminal device 10, high priority is set in the order of terminal mode, mass storage, and music player. If this is the case (this priority may be determined in advance by the user or before the user sets it), the terminal mode function is first determined as the search target. The

  Next, the USB function detection unit 110 determines whether or not the mobile terminal device 10 has the function determined as the search target (step 110). By the way, the time required for detecting each function differs for each function.

  FIG. 5 is a diagram illustrating a software (protocol) configuration of a USB device corresponding to each function. When the function of the music player of the mobile terminal device 10 is used by the in-vehicle device 50, the mobile terminal device 10 is provided with a USB driver and a SICDC (Still Image Capture Device Class) driver as shown in FIG. For example, it takes 3 seconds to detect the music player function of the mobile terminal device 10 in order to confirm the presence of these.

  Further, when the in-vehicle device 50 uses the mass storage function of the mobile terminal device 10, the mobile terminal device 10 is provided with a USB driver and an MSC (Mass Storage Class) driver as shown in FIG. For example, it takes 1 second to detect the mass storage function of the mobile terminal device 10 in order to confirm the presence of these devices.

  When the terminal mode function of the mobile terminal device 10 is used by the in-vehicle device 50, the mobile terminal device 10 includes a USB driver and a CDC (Communication Device Class) driver as shown in FIG. In addition, the mobile terminal device 10 and the in-vehicle system are mounted after implementing TCP / IP (Transmission Control Protocol / Internet), UPnP (Universal Plug and Play), VNC (Virtual Network Computing), and RTP (Real-time Transport Protocol) protocols. Confirmation by communication with the device 50 is required, and detection of the terminal mode function of the mobile terminal device 10 requires, for example, 10 seconds to 30 seconds (when the terminal mode function is provided, detection is performed in 10 seconds). If you do not have it, you will need to send and receive data several times. It requires a degree).

  For example, after the terminal mode function is determined as a search target in step 108, the USB function detection unit 110 detects that the mobile terminal device 10 has the terminal mode function in 10 seconds, and in step 110 affirms. Make a decision. Next, the function selection screen creation unit 120 adds an activation icon for instructing activation of a specific operation (processing by the TM processing unit 104) corresponding to the terminal mode function detected by the USB function detection unit 110 to the function selection screen. (Step 112). The function selection screen to which the activation icon is added is displayed on the display unit 55 by the display processing unit 56.

  FIG. 6 is a diagram illustrating a display example of the function selection screen, in which a startup icon corresponding to the terminal mode function is added. In the function selection screen shown in FIG. 6, an activation icon S <b> 1 that can be selected by the user to instruct the start of processing by the TM processing unit 104 is added to the function selection screen shown in FIG. 4.

  FIG. 7 is a diagram showing another display example of the function selection screen, and further shows a state where an activation icon S2 corresponding to the mass storage function is added. FIG. 8 is a view showing another display example of the function selection screen, and further shows a state where an activation icon S3 corresponding to the music player function is added.

  When each activation icon is added to the function selection screen in this way, the process returns to step 104 each time and the determination of whether or not activation icon is selected is repeated. If the portable terminal device 10 does not have the search target function, a negative determination is made in the determination in step 110, and the process returns to step 104 without adding the activation icon to the function selection screen, and the activation icon is selected. The subsequent determination is repeated.

  Further, if any activation icon is selected by the user while the function selection screen shown in any of FIGS. 6 to 8 is displayed, an affirmative determination is made in the determination of step 104. Next, the function selection processing unit 122 gives an activation instruction corresponding to the selected activation icon to the music player processing unit 100 or the like corresponding to the activation icon. Specifically, when the activation icon S1 is selected, an activation instruction is sent to the TM processing unit 104. When the activation icon S2 is selected, an activation instruction is sent to the mass storage processing unit 102. When the activation icon S3 is selected, an activation instruction is sent to the music player processing unit 100. Thereafter, the specific operation is executed in the processing unit that has received the activation instruction (step 114).

  As described above, in the present embodiment, detection of a plurality of functions provided in the mobile terminal device 50 is performed on the in-vehicle device 50 side, and activation icons indicating the presence of each function are added to the function selection screen in the detected order. Therefore, the user can select one of a plurality of functions that can be executed in correspondence with the connected mobile terminal device 10 by using the function selection screen. Moreover, the specific operation | movement of the vehicle-mounted apparatus 50 corresponding to each activation icon can be started only by selecting the activation icon in a function selection screen, and the operativity by simplification of operation becomes possible.

  Further, when detecting a plurality of functions provided in the mobile terminal device 10, detection is performed in descending order of priority, and activation icons are added to the function selection screen in descending order of priority. The waiting time until a function is selected can be shortened. In addition, when the priority order is set according to the user's instruction using the priority order setting unit 124, the display order of the activation icons can be set for each user, and the use is desired for each user. The time until the start of the specific operation corresponding to the function can be shortened.

  In addition, when the priority is set higher in the order in which the activation time of the corresponding specific operation is short, it is possible to select a function that minimizes the waiting time until the specific operation is started. Further, when the highest priority is set for the function corresponding to the specific operation executed last when the mobile terminal device 10 was connected last time, the function executed last time may be selected first. It is possible to improve usability when the user selects the same function.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, the operation procedure for detecting the plurality of functions provided in the mobile terminal device 10 in the descending order of priority has been described with reference to the flowchart shown in FIG. The functions may be detected in the order corresponding to the contents. In this case, in step 108 shown in FIG. 3 (detection functions are determined in descending order of priority), the contents of the descriptor are acquired from the mobile terminal device 10 (only the necessary part is sufficient instead of the whole), and the description of this descriptor is performed. What is necessary is just to replace with operation | movement of step 108A which determines a detection function in order. This makes it possible to search for functions in the order in which the specifications of the mobile terminal device 10 are reflected.

  In the above-described embodiment, the case where the in-vehicle device 50 and the mobile terminal device 10 are connected via the USB interface has been described. However, other methods may be used for the connection between them. For example, a case where the connection is made via other wired connection means such as an IEEE 1394 cable or a case where the connection is made via a wireless connection means such as a wireless LAN or Bluetooth can be considered. When these other connection means are used, the USB interface units 26 and 62 may be replaced with interface units corresponding to the connection units.

  In the above-described embodiment, the case where the mobile terminal device 10 is connected to the in-vehicle device 50 has been described. However, other USB devices that can be connected via a USB interface (or other connection means) include a plurality of devices. The present invention can also be applied to other portable terminal devices having functions. For example, it may be possible to use a portable terminal device that does not have a telephone function, a tablet-type portable terminal device, or the like. Further, although the in-vehicle device 50 is used as the information processing device, the present invention can also be applied to the case where another information processing device mounted or installed other than the vehicle is used.

  In the above-described embodiment, the function selection screen including the activation icon is displayed. However, instead of the activation icon, a function selection screen in which a character string indicating a specific operation to be activated is displayed as a list is used. May be.
