(function)
A function given to the installation-destination mobile device 100 by the application software of the present invention, and a cooperation method between the mobile device 100 and the external device 200 as one embodiment of the present invention will be described.

  First, the connection between the connection unit 121 of the mobile device 100 and the connection unit 221 of the in-vehicle device 200 is established with the application activated. In this embodiment, either USB method or USB + RCA method is selected for this connection. When the connection is established, the primary signal is transmitted from the in-vehicle device 200 in the process of the first communication between the mobile device 100 and the in-vehicle device 200, and the portable device 100 receives the primary signal through the connection unit 121. (FIG. 2 / STEP02).

  The “primary signal” is a signal for specifying a communication protocol employed in the in-vehicle device 200. The primary signal may be transmitted / received as a single signal, or may be transmitted / received multiple times after being divided. In the first period communication, signals other than the primary signal may be transmitted and received between the mobile device 100 and the in-vehicle device 200.

  Whether the arithmetic processing unit 110 of the portable device 100 has the same communication protocol employed in the portable device 100 stored in the storage device 104 as the communication protocol of the in-vehicle device 200 specified by the primary signal. It is determined whether or not (FIG. 2 / STEP04).

  When the determination result is affirmative (FIG. 2 / STEP04... YES), communication between the portable device 100 and the in-vehicle device 200 is continued, and the in-vehicle device 200 is in the process of the second communication after the first communication. The secondary signal (first signal) is transmitted from the mobile device 100, and the portable device 100 receives the secondary signal through the connection unit 121 (FIG. 2 / STEP06).

  The “secondary signal” is a signal for specifying the type of a communication sequence (defined by the content of a transmitted / received signal and a transmission / reception pattern) for cooperation between the mobile device 100 and the in-vehicle device 200. Similar to the primary signal, the secondary signal may be transmitted and received as a single signal, or may be divided and transmitted multiple times. In the second communication, a signal other than the secondary signal may be transmitted and received between the mobile device 100 and the in-vehicle device 200.

  On the other hand, when the determination result is negative (FIG. 2 / STEP04... NO), the mobile device 100 determines that the currently connected in-vehicle device 200 is a model not to be connected and receives the secondary signal. Without communication, the communication with the in-vehicle device 200 is stopped.

  The arithmetic processing unit 110 of the mobile device 100 determines the type of communication sequence for cooperation with the in-vehicle device 200 based on the secondary signal (FIG. 2 / STEP08).

  When it is determined that the communication sequence is the first type communication sequence (FIG. 2 / STEP08... T1), the mobile device 100 receives the identifier from the in-vehicle device 200 (FIG. 2 / STEP10). The “first type communication sequence” means a communication sequence that can be identified by an identifier (more precisely, a first identifier).

  As shown in FIG. 3, the identifier ID includes four identifiers ID1 to ID4. The first identifier ID1 is an identifier for identifying a communication sequence unique to each in-vehicle device 200, and thus each in-vehicle device, such as a manufacturing number of the in-vehicle device 200. The second identifier ID2 is an identifier for identifying an information output method through the output device 202 of the in-vehicle device 200. The third identifier ID3 is an identifier for identifying the manufacturer (maker) of the in-vehicle device 200. The fourth identifier ID4 is an identifier for identifying the version of the application installed in the in-vehicle device 200.

  The determination process based on the second identifier ID2 (see FIG. 2 / STEP 12) may be executed based on the first identifier ID1 instead of the second identifier ID2. Of the four types of identifiers ID1 to ID4, the three types of identifiers ID2 to ID4 other than the first identifier ID1 may be omitted, and the identifier ID may be configured only by the first identifier ID.

  The arithmetic processing unit 110 of the portable device 100 determines the information output method in the in-vehicle device 200 based on the second identifier constituting the identifier (FIG. 2 / STEP 12). When it is determined that the information output method is the first method (FIG. 2 / STEP12... P1), generation or preparation of information whose information format is f (P1) corresponding to the first method is started ( FIG. 2 / STEP 14). When it is determined that the information output method is the second method (FIG. 2 / STEP12... P2), generation or preparation of information whose information format is f (P2) corresponding to the second method is started ( FIG. 2 / STEP 16). The number of information output methods may be three or more.

  The first identifier ID1 and the second identifier ID2 are transmitted and received between the portable device 100 and the vehicle-mounted device 200 as a group of identifier IDs, and separately and simultaneously or at different times. May be transmitted to and received from. As will be described later, the transmission / reception time of the second identifier may be earlier than the transmission / reception time of the first identifier as the time required for generating or preparing information in a format (data format) determined according to the second identifier is longer. .

  In the present embodiment, whether the “touch panel method (first method)” or the “jog dial method (second method)” is determined by the second identifier as the operation method of the in-vehicle device 200 having a display as the output device 202. The When the operation method of the in-vehicle device 200 is a touch panel method, the image information output method is an output method that requires output of an operation button image or the like. On the other hand, when the operation method of the in-vehicle device 200 is a method other than the touch panel method, the image information output method is an output method that does not require image output such as operation buttons.

  For this reason, depending on the operation method of the in-vehicle device 200, preparation of image content with different values of parameters such as size, aspect ratio, and resolution is started depending on whether or not to avoid duplication with the operation button. The “Image information” includes image content such as a movie, a television program, a game, or a map for navigation.

  In addition, the output method of audio information of the in-vehicle device 200 provided with a plurality of speakers as the output device 202 is a method in which the audio output pattern from the plurality of speakers is changed according to the content of the acoustic content (first method). (Second scheme) is determined by the second identifier. When the audio output method of the in-vehicle device 200 is the first method, it is necessary to select a speaker to be output according to the type of audio information (acoustic content) such as music or a message. On the other hand, when the sound output method of the in-vehicle device 200 is a method other than the method, sound may be output from all the speakers uniformly regardless of the type of the acoustic content. For this reason, according to the audio output method of the in-vehicle device 200, preparation of acoustic content in which the presence / absence of parameters for specifying audio output patterns by a plurality of speakers is different is started.

  The portable device 100 determines a communication sequence for cooperation with the in-vehicle device 200 based on the first identifier constituting the identifier (FIG. 2 / STEP 18). When it is determined that the communication sequence is the first communication sequence (FIG. 2 / STEP18... S1), the connection method of the mobile device 100 and the in-vehicle device 200 is determined (FIG. 2 / STEP20). The “first communication sequence” means a communication sequence in which the communication signal method needs to be changed or adjusted according to the connection method.

  When it is determined that the connection method is the first connection method (FIG. 2 / STEP20... Q1), the signal method is adjusted to the first signal method g (Q1) corresponding to the first connection method (FIG. 2 / STEP22). ). When it is determined that the connection method is the second connection method (FIG. 2 / STEP20... Q2), the signal method is adjusted to the second signal method g (Q2) corresponding to the second connection method (FIG. 2 / STEP24). ). In the present embodiment, one of the two types of connection methods is selected according to two types of connection methods (for example, USB method and USB + RCA method). There may be three or more types of connection methods to be selected. Then, in accordance with the signal system after the adjustment and the first communication sequence S1, cooperation between the mobile device 100 and the in-vehicle device 200 is executed (FIG. 2 / STEP 26).

  When it is determined that the communication sequence is the second communication sequence (FIG. 2 / STEP18... S2), the cooperation between the mobile device 100 and the in-vehicle device 200 is executed according to the second communication sequence S2 (FIG. 2 / STEP28). ). The “second communication sequence” means a communication sequence in which the communication signal method does not need to be changed or adjusted according to the connection method.

  When it is determined that the communication sequence is the second type communication sequence (FIG. 2 / STEP08... T2), the cooperation between the mobile device 100 and the vehicle-mounted device 200 is executed according to the third communication sequence S3 (FIG. 2 / (STEP 30). The “second type communication sequence” means a communication sequence that is not identified by an identifier (exactly the first identifier). The “third communication sequence” is the only communication sequence corresponding to the second type communication sequence in the present embodiment.

  In communication according to the third communication sequence, determination of the connection method between the portable device 100 and the external device 200 and adjustment of the signal method according to the determination result may be executed (FIG. 2 / STEP 20, 22, 24). reference).

  When the mobile device 100 and the in-vehicle device 200 cooperate with each other according to each communication sequence, a function corresponding to a predetermined application of the mobile device 100 is exhibited. For example, the vehicle current position calculated based on the GPS signal by the navigation application of the mobile device 100, the route to the target position searched based on the map information stored in the storage device 104, and the map information are mounted on the vehicle. After being transmitted to the device 200, it may be output through the output device 202.

  In addition, image information including character information necessary for control may be transmitted to the in-vehicle device 200 by an application for controlling the in-vehicle device such as an air conditioner and then output through the output device 202. Further, the audio content may be transmitted to the in-vehicle device 200 by the music application and then output through the output device 202.

(Function and effect)
According to the mobile device 100 of the present invention, the “first identifier” received from the in-vehicle device 200 and the “connection method” between the mobile device 100 and the in-vehicle device 200 simply by connecting the mobile device 100 and the in-vehicle device 200. Depending on the combination pattern, the communication signal system for cooperation with the in-vehicle device 200 is automatically adjusted (see FIG. 2 / STEP 18... S 1 → STEP 20... Q 1, Q 2 → STEP 22 and 24). Here, in the case of a communication sequence (second communication sequence) that does not require connection method determination and, in turn, communication signal method change setting in cooperation with the in-vehicle device 200, the in-vehicle device is as much as the determination is omitted. The speed of cooperation with the system 200 can be increased (see FIG. 2 / STEP 18... S2 → STEP 28).

  Furthermore, information in a format determined according to the information output form determined based on the “second identifier” received from the in-vehicle device 200 before the start of communication for adjusting the communication signal system is output information through the in-vehicle device 200. Generated or prepared as. As a result, it is possible to speed up the adjustment of the communication signal system with the in-vehicle device 200 and further speed up the information output by cooperation with the in-vehicle device 200 according to the communication signal system after the adjustment (FIG. 2 / STEP 12... (Refer to P1, P2 → STEP 14, 16).

  Further, when the first identifier is not necessary for adjusting the communication sequence (when the communication sequence is classified as the second type sequence), reception of the first identifier and further processing associated with the reception are not necessary. As a result, the adjustment of the communication signal system with the in-vehicle device 200 can be speeded up, and further the cooperation with the in-vehicle device 200 according to the communication signal system after the adjustment can be accelerated (FIG. 2 / STEP08... T2 → STEP30). reference).
