Contents of the invention

However, there are many types of portable devices that cooperate with the above-mentioned type of on-vehicle information processing devices: cellular phones, PDAs (personal digital assistants, personal digital assistants), portable audio devices, and the like. In addition, the functions that can be implemented in cooperation with the vehicle-mounted information processing device are gradually diversified, and the functions include, for example, a hands-free function, an audio function, and a phonebook function. In addition, the functions that can be realized even in the same type of mobile phone differ from model to model. For example, there are mobile phones that have only a hands-free function as a function that can be realized in cooperation with an in-vehicle information processing device, and mobile phones that have a hands-free function and an audio function (a function to play music, etc.).

Therefore, it is preferable that the in-vehicle information processing device maintain various functions so as to correspond to various portable devices as much as possible, and provide operation screens for various functions corresponding thereto.

However, with the diversification of portable devices as described above, there is a possibility that the functions held by the portable device side and the functions held by the in-vehicle information processing device may not match. Therefore, if the operation screen provided by the in-vehicle information processing device is fixedly (samely) generated regardless of the model or type of the connected mobile device, there is a possibility that the user may be confused. For example, if a mobile phone with only the hands-free function is connected but an operation screen corresponding to the hands-free function and the audio function is provided, the user cannot actually perform the audio function although the user can apparently select the audio function. Such a situation confuses the user and is therefore not preferable.

Therefore, an object of the present invention is to provide an in-vehicle information processing device and the like capable of presenting an appropriate operation screen corresponding to a function possessed by a connected portable device.

In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a vehicle-mounted information processing device is provided. The vehicle-mounted information processing device realizes various functions in cooperation with a portable device connected in the vehicle, and includes:

communication means for communicating with the portable device; and

a screen generating device that generates an operation screen corresponding to various functions that can be realized in cooperation with the portable device,

The screen generation device specifies a function that can be realized in cooperation with the connected portable device among various functions that can be realized in cooperation with the portable device based on the information of the portable device connected via the communication device, and The determined achievable functions correspondingly generate different operation screens.

According to the present invention, it is possible to obtain an in-vehicle information processing device or the like capable of presenting an appropriate operation screen corresponding to a function possessed by a connected portable device.

An operation screen (described later) generated by the operation screen generation device 12 is displayed on the display device 14 .

The portable device 20 is a portable device such as a cellular phone, a PDA, a portable audio player, a DVD player, a digital camera, and has a Bluetooth communication function. The portable device 20 is brought into the vehicle by the user with, for example, the Bluetooth communication function being set to ON. The portable device 20 has a function (hereinafter, referred to as a portable holding function) that can be implemented in cooperation with the vehicle-mounted information processing device 10 via Bluetooth communication. This portable holding function may vary depending on the type or model of the portable device 20 . In addition, in order to actually realize the portable storage function in cooperation with the vehicle-mounted information processing device 10, it is necessary for the vehicle-mounted information processing device 10 to have a corresponding function (hereinafter referred to as the vehicle-mounted device storage function).

These various portable holding functions are realized using a Bluetooth profile (hereinafter, simply referred to as a profile). This profile is typically a standard profile established by Bluetooth SIG, an industry group, but may also include a unique profile in which a manufacturer's own function is installed. Also, a profile is a type of protocol that defines technical standards including the sequence or timing of sending and receiving commands and data between the mobile device 20 and the in-vehicle information processing device 10 , the definition of commands, the definition of variables, and the like.

The profile as standard has: for example, the profile that is used to realize above-mentioned hands-free function: HFP (HandsFreeProfile), the profile that is used to realize above-mentioned phone book function: PBAP (PhoneBookAccessProfile), is used to realize above-mentioned audio frequency/ The profile of the video function: AVP (AudioVisualProfile), and the profile for realizing the above-mentioned mail function: MAP (MessageAccessProfile). In addition, the profile AVP for realizing the audio/video function is composed of two profiles A2DP (AdvancedAudioDistributionProfile) and AVRCP (AudioVisualRemoteControlProfile).

Therefore, the profile HFP and the profile PBAP are held in the portable device 20 having the hands-free function and the phone book function as a portable holding function, and the hand-free function, the phone book function, and the audio/video function are held as a portable holding function. The profile HFP, profile PBAP, and profile AVP are stored in the portable device 20 of . Similarly, various profiles corresponding to the vehicle-mounted device holding function are stored in the vehicle-mounted information processing device 10 . All the profiles corresponding to the above-mentioned four profiles (HFP, MAP, AVP, and MAP) can also be kept in the vehicle-mounted information processing device 10, so that the functions realized between various portable devices 20 can be maintained. maximize.

FIG. 2 is a flowchart showing an example of main processing realized by the in-vehicle information processing device 10 of this embodiment. The processing routine shown in FIG. 2 is started when, for example, the engine of the vehicle is started (ie, when the ignition switch is turned on). Here, as an example, profiles corresponding to the above-mentioned four profiles (HFP, MAP, AVP, and MAP) are held in the in-vehicle information processing device 10 .

In step 200, Bluetooth communication with the portable device 20 brought into the vehicle compartment is started via the Bluetooth communication device 11 . In addition, this Bluetooth communication may be started automatically when the Bluetooth communication function is set to an on state in the portable device 20 , but in other cases, for example, it is started by a user's operation.

In step 202 , the profile held by the portable device 20 is detected by the Bluetooth communication device 11 . The detection of this profile is carried out, for example, by a link establishment procedure normally carried out between the Bluetooth communication device 11 and the portable device 20 .

In step 204 , the processing unit 12 a confirms a match between the profile on the portable device 20 side detected in the process of step 202 and the profile corresponding to the in-vehicle information processing unit 10 . For example, when the profile HFP and profile PBAP are detected for the portable device 20 brought in this time, these two profiles HFP and profile PBAP match the profile on the side of the in-vehicle information processing device 10 . In addition, when the profile HFP, profile PBAP, and profile AVP are detected for the portable device 20 brought in this time, these three profiles HFP, profile PBAP, and profile AVP are related to the Profile matching. In addition, when the in-vehicle information processing device 10 holds profiles corresponding to all the portable holding functions that the portable device 20 can hold, the profile of the portable device 20 side detected in the above-mentioned step 202 may be unconditionally checked. Compatibility (that is, step 204 can also be omitted in essence).

In step 206, the processing device 12a selects/determines a function (vehicle holding function) operated on the in-vehicle information processing device 10 side based on the processing result of the above-mentioned step 204. For example, when matching of the profile HFP and the profile PBAP is confirmed, the hands-free function and the phonebook function are selected/determined. In addition, when the matching of the profile HFP, profile PBAP, and profile AVP is confirmed, the hands-free function, the phonebook function, and the audio/video function are selected/determined.

In step 208 , in response to an instruction from the processing device 12 a , the rendering device 12 b draws an operation screen with content corresponding to the function specified in the processing of the above-mentioned step 206 , and outputs it to the display device 14 .

For example, when the hands-free function and the phone book function are selected/determined in the processing of the above-mentioned step 206, as shown in FIG. It is the operation screen of the contact switch 70b for operating the phonebook function. In addition, on the contact switch 70a for operating the hands-free function and the contact switch 70b for operating the phone book function, characters representing the respective switch functions (in the illustrated example, "hands-free" and " phone book"). Thus, the user can only operate the hands-free function and the phone book function that can be realized. For functions other than the hands-free function and the phone book function (for example, functions that cannot be realized such as audio/video functions), the operation itself cannot be performed. Can prevent unnecessary confusion to the user. In addition, the operation screen shown in FIG. 3(A) can transition to the operation screen for operating the lower (lower layer) function when the user operates any one of the touch switches 70a and 70b. For example, when a user who wants to make a hands-free call operates the touch switch 70a, the operation screen shown in FIG. touch switch, or the touch switch for sending the operation screen, etc.). In addition, the number of levels may be arbitrary, and may be three or more.

Likewise, when the hands-free function, the phonebook function, and the audio/video function are selected/determined in the processing of the above-mentioned step 206, for example, as shown in FIG. Operation screens of the touch switch 70a, the touch switch 70b for operating the phonebook function, and the touch switch 70c for operating the audio/video function. In addition, a character indicating the switch function ("audio" in the illustrated example) may be drawn on the touch switch 70c for operating the audio/video function. Thus, the user can only operate the hands-free function, the phone book function, and the audio/video function that can be realized. function), the operation itself cannot be performed, thus preventing unnecessary confusion to the user. In addition, when the user operates any one of the touch switches 70a, 70b, 70c on the operation screen shown in FIG. For example, when a user who wants to listen to music downloaded to the portable device 20 operates the touch switch 70c, the operation screen shown in FIG. Operation screen for contact switches indicating play, fast forward, stop, etc.). In addition, the number of levels may be arbitrary, and may be three or more.

As described above, according to the process shown in FIG. 2 , when the user's portable device 20 is connected to the vehicle-mounted information processing device 10 via Bluetooth communication, by confirming several functions held by the vehicle-mounted information processing device 10 (vehicle device holding function) Matching with the portable holding function of the portable device 20 brought in by the user, it is possible to generate and output an operation screen that can only operate functions that can be operated by the portable device 20 brought in by the user. Thereby, the problem pointed out in the section "Problems to be Solved by the Invention", that is, the problem of confusing the user due to the operation screen having operation switches related to functions that cannot be realized in practice, can be solved.

FIG. 4 is a flowchart showing another example of main processing that can be realized by the in-vehicle information processing device 10 of this embodiment. The processing routine shown in FIG. 4 is started, for example, when the engine of the vehicle is started, similarly to the processing routine shown in FIG. 2 . Here, as an example, the in-vehicle information processing device 10 holds profiles corresponding to the above-mentioned four profiles (HFP, MAP, AVP, and MAP).

The processing other than step 402, that is, the processing of steps 400, 404, 406, and 408 are the same as the processing of steps 200, 204, 206, and 208 of the processing shown in FIG.

In step 402, the profile held by the portable device 20 is detected by the processing unit 12a based on the initial registration information related to the portable device 20 brought into the vehicle compartment. The registration information is stored in memory by the processing means 12a upon initial registration of the portable device 20 . The registration information includes information on the profile (portable holding function) held by the mobile device 20 . The registration information may also include other information such as the model and manufacturer of the portable device 20 .

As described above, according to the processing shown in FIG. 4 , similarly to the processing shown in FIG. 2 , when the user's portable device 20 is connected to the on-board information processing device 10 via Bluetooth communication, the on-board information processing is confirmed based on the registration information. Matching between several functions held by the device 10 (vehicle holding function) and the portable holding function of the portable device 20 brought in by the user can generate/output a function that can only be operated by the portable device 20 brought in by the user. The operation screen of the function. Thereby, it is possible to eliminate the problem of confusing the user due to the operation screen having the operation switches related to the functions that cannot be realized in practice.
