  As described above, portable devices such as mobile phones and portable information terminal devices and in-vehicle information devices such as navigation devices and audio devices have overlapping functions, but the specifications of each function of portable devices and information devices are different. In comparison, portable devices are often inferior to information devices in terms of display screen size, speaker performance, and the like. Therefore, if the function of the mobile device is implemented by the in-vehicle information device, it is possible to realize a higher-grade function than the mobile device.

  However, when the function of the mobile device is to be implemented by the in-vehicle information device, the function of the in-vehicle information device is not necessarily superior to the function of the mobile device, so that a higher-grade function than the mobile device can be realized. There is a problem that is not always.

  The device disclosed in Patent Document 1 uses the display unit of the portable information terminal device as the display unit of the navigation device in order to eliminate the need for investment in the display unit of the navigation device. However, it does not replace the functions of mobile devices with a higher grade.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an in-vehicle information device that performs a function of a mobile device in a higher grade than a mobile device.

  In order to achieve the above object, the first feature of the present invention is that the specification of the function of the portable device acquired from the portable device via the communication means and the specification of the function overlapping with the portable device stored in the storage means are provided. In comparison, if the function of the mobile device is implemented with a function that overlaps with the mobile device, check whether the function is upgraded, and if the function of the mobile device is performed with the function that overlaps with the mobile device, the function is When it is confirmed that the upgrade is performed, the function overlapping with the portable device is performed instead of the portable device.

  In such a configuration, compare the specifications of the functions that overlap with the mobile devices and the specifications of the functions of the mobile devices, and confirm that the functions are upgraded when the functions of the mobile devices are implemented with the functions that overlap with the mobile devices. In this case, since the function overlapping with the portable device is performed instead of the portable device, the function of the portable device can be implemented with a higher grade than the portable device.

  In this case, a function list whose performance is indicated by a numerical value for each function of the mobile device is acquired from the mobile device, and a function list whose performance is indicated by a numerical value is stored for each function overlapping with the function of the mobile device. By comparing the numerical values shown in the function list, it is possible to confirm whether or not the function is upgraded when the function of the portable device is implemented with the function overlapping the function of the portable device.

  The second feature of the present invention is that the specifications of the functions of the in-vehicle information device acquired from the in-vehicle information device via the communication means are compared with the specifications of the functions overlapping with the in-vehicle information device stored in the storage means. When the function that overlaps with the in-vehicle information device is implemented by the function of the in-vehicle information device, whether the function is upgraded or not, and when the function that overlaps with the in-vehicle information device is implemented by the function of the in-vehicle information device When it is confirmed that the function is upgraded, the in-vehicle information device is requested to be implemented by the function of the in-vehicle information device instead of the function overlapping with the in-vehicle information device via the communication means.

  In such a configuration, the function specifications of the in-vehicle information device are compared with the specifications of the function overlapping with the in-vehicle information device, and the function is graded when the function overlapping with the in-vehicle information device is implemented by the function of the in-vehicle information device. If the function of the in-vehicle information device is confirmed to be upgraded when the function that overlaps with the in-vehicle information device is performed by the function of the in-vehicle information device, the function of the in-vehicle information device is used instead of the portable device. Since it is requested to be implemented, it is possible to replace the functions of the portable device with a higher grade than the portable device.

  The third feature of the present invention is that the user confirms whether or not to implement the function of the in-vehicle information device in place of the function overlapping with the in-vehicle information device, and the in-vehicle information in place of the function overlapping with the in-vehicle information device. When it is confirmed that the function is performed by the function of the device, the vehicle information device is requested to be performed by the function of the in-vehicle information device instead of the function overlapping with the in-vehicle information device.

  In such a configuration, when it is confirmed by the user that the function of the in-vehicle information device is performed instead of the function that overlaps with the in-vehicle information device, the function of the in-vehicle information device is replaced with the function that overlaps with the in-vehicle information device. Since it is requested to implement, it can be requested to implement with the function of the in-vehicle information device instead of the function overlapping with the in-vehicle information device according to the user's intention.

  In FIG. 2, the specifications (performance) of each function of the mobile phone 2 and the navigation device 1 are shown by text, but actually the performance is shown using numerical values for each function. For example, the drawing size is 7, 6, 5, 4, 3, 2, in order of 1280 × 1024, 1280 × 960, 1280 × 720, 1152 × 864, 1024 × 768, 800 × 600, 640 dots × 480. 1 for the processed image format, the number of formats that can be displayed is shown as a numerical value indicating the performance, and the sound field is in the order of 5.1 channel surround, surround, stereo, and monaural. 4, 3, 2, 1. In the present embodiment, the higher the performance, the larger the numerical value shown in the function list.

  Next, each process of the control unit 21 of the mobile phone 2 and the control circuit 17 of the navigation device 1 will be described with reference to the flowchart shown in FIG. When the ignition switch is turned on, the navigation device 1 is in an operating state, and the control circuit 17 starts the process shown in FIG. 3 in parallel with the process of specifying the current position based on the signal input from the position detector 16. . The control unit 21 of the mobile phone 2 starts the process shown in FIG. 3 when the power of the mobile phone 2 is turned on in accordance with the operation of the operation unit of the user.

  First, the control unit 21 of the mobile phone 2 determines an access condition with an external device (here, the navigation device 1) by short-range wireless communication (S200). Specifically, it is determined whether or not near field communication is permitted based on whether or not a flag indicating permission for near field communication is set in the internal memory.

  When the flag indicating permission of short-range wireless communication is not set, the determination in S200 is NO and the determination in S200 is repeated. If a flag indicating permission of short-range wireless communication is set, the determination in S202 is YES, and a short-distance wireless communication with a communication partner is enabled via the short-range communication interface 17a. In the following description, it is assumed that a flag indicating permission of near field communication is set in the internal memory.

  On the other hand, the control circuit 17 determines the presence / absence of the mobile phone 2 based on whether or not the proximity sensor detects the presence of the mobile device at a predetermined position (S100). When the mobile phone 2 is taken out of the vehicle by the user and the mobile phone 2 does not exist at a predetermined position, the determination in S100 is repeated.

  When the user gets into the vehicle and installs the mobile phone 2 at a predetermined position, the determination in S100 is YES, and then polling is performed via the short-range communication interface 17a (S102).

  The control unit 21 of the mobile phone 2 makes a polling response in response to polling from the control circuit 17 (S202).

  Although not shown, the control circuit 17 of the navigation device 1 returns to S100 when there is no polling response from the control unit 21 of the mobile phone 2. If there is a polling response from the control unit 21 of the mobile phone 2, next, the mobile device of the communication partner is confirmed with the user (S104). Specifically, identification information (ID) is acquired from the portable device via the short-range communication interface 17a, and the display device 14 can display a portable device that can be communicated based on the acquired identification information of the portable device. Display on the screen. When there is a polling response from a mobile device other than the mobile phone 2 and the identification information of a plurality of mobile devices is acquired, a list of the plurality of mobile devices is selectably displayed on the display screen of the display device 14. The control circuit 17 communicates with a mobile device selected by the user from among the mobile devices displayed on the display screen of the display device 14. Here, it is assumed that the mobile phone 2 is selected as the communication partner by the user's operation.

  When the mobile phone 2 is selected by the user's operation, the control circuit 17 and the control unit 21 next perform authentication processing (S106, S204). Specifically, the identification information such as the mutual authentication code is exchanged, and when it is confirmed that the registered party is a legitimate partner registered in advance, the authentication process ends normally.

  The control circuit 17 of the navigation device 1 determines whether or not the authentication process of S106 has been completed normally (S108). If the authentication information of the mobile phone 2 is not registered, the determination in S108 is NO, and next, communication process recording is performed (S110). Specifically, a message indicating that the authentication process has ended abnormally is displayed on the display screen of the display device 14, and the fact that the authentication process has ended abnormally is stored in the memory, and the process returns to S100.

  On the other hand, the control unit 21 of the mobile phone 2 also determines whether or not the authentication process of S204 is normal, and proceeds to S206 if the authentication process ends normally, although not shown. If the authentication process ends abnormally, a message indicating that the authentication process has ended abnormally is displayed on the display unit, and the process returns to S200.

  When the authentication processes in S106 and S204 are normally completed, the control circuit 17 and the control unit 21 perform a function list exchange process (S112 and S206). Specifically, the control circuit 17 of the navigation device 1 acquires a function list in which the specifications of the functions of the mobile phone 2 are stored from the control unit 21 of the mobile phone 2, and the control unit 2 of the mobile phone 2 The function list in which the specifications of the functions of the navigation device 1 are stored is acquired from the control circuit 17 of one.

  Next, the control circuit 17 of the navigation device 1 stores the acquired function list of the mobile phone 2 in the memory (S114), and the control unit 21 of the mobile phone 2 stores the acquired function list of the navigation device 1 in the internal memory. Store (S208).

  Next, the control circuit 17 and the control unit 21 compare the specifications of the exchanged function list with the specifications of their own function list, and implement the functions implemented by the mobile phone 2 in the navigation device 1. In this case, it is confirmed whether or not the function is upgraded (S116, S210).

  For example, when the mobile phone 2 is playing a video of a music video stored in the internal memory, items relating to video playback among the items (1) to (12) described above, that is, a drawing size, a processed image format, For the five items of voice processing data, sound field, and voice output, the performances of the mobile phone 2 and the navigation device 1 are compared from the numerical values shown in the mutual function lists, and the functions implemented by the mobile phone 2 are shown in the navigation device 1. Check if you can upgrade with. Specifically, when the number of excellent items is larger than that of the mobile phone 2, it is determined that the function performed by the mobile phone 2 can be upgraded by the navigation device 1.

  In addition, for example, when the mobile phone 2 is displaying a map, among the items (1) to (12), items related to map display, that is, four items of drawing size, processed image format, map data, and positioning method. Then, the functions of the mobile phone 2 and the navigation device 1 are compared with each other based on the numerical values shown in the mutual function list, and it is confirmed whether or not the functions implemented by the mobile phone 2 can be upgraded by the navigation device 1.

  When it is confirmed that the navigation device 1 can be upgraded in S210, the control unit 21 of the mobile phone 2 next confirms to the user whether or not the function of the mobile phone 2 is upgraded by the navigation device 1. Is displayed on the display unit (S212). For example, a switch for executing switching to the navigation device 1 and a stop switch for canceling the switching are displayed together with a message such as "Can the mobile phone function be upgraded with the navigation device, but is it switched?" Selectable display on the display. If it is confirmed in S210 that the navigation apparatus 1 is not upgraded, the process returns to S200 without performing the display in S212.

  Next, it is determined whether or not the function of the mobile phone 2 is upgraded by the navigation device 1 (S214). Specifically, when the changeover switch is selected by the user's operation, it is determined that the function of the mobile phone 2 is upgraded by the navigation device 1, and when the stop switch is selected by the user's operation, the mobile phone 2 is It is determined that the function of the telephone 2 is not upgraded by the navigation device 1.

  Here, when the changeover switch is selected by the user's operation, the determination in S214 is YES, and then a function upgrade request is made (S216). Specifically, information (hereinafter referred to as upgrade request information) requesting to replace the function performed by the mobile phone 2 is transmitted to the navigation device 1 via the short-range communication interface 17a. The upgrade request information includes information indicating the function being performed by the mobile phone 2. For example, when the mobile phone 2 is playing a video of a music video stored in the internal memory, the upgrade request information includes information indicating that the mobile phone 2 is playing a video of a music video stored in the internal memory. Is included. When the mobile phone 2 is displaying a map, the upgrade request information includes information indicating that the mobile phone 2 is displaying a map.

  When receiving the upgrade request information, the control circuit 17 of the navigation device 1 performs mobile function substitution processing that is processed instead of the function of the mobile phone 2 (S118).

  For example, when the upgrade request information includes information indicating that the mobile phone 2 is playing a music video stored in the internal memory, the control unit of the mobile phone 2 via the short-range communication interface 17a. The video signal and audio signal being played back are acquired from 21, the video corresponding to the acquired video signal is displayed on the display screen of the display device 14, and the audio corresponding to the acquired audio signal is output from a speaker (not shown). Let

  As a result, it is possible to reproduce the video with a large screen and high sound quality as compared with the case where the music video is reproduced on the mobile phone 2.

  When the upgrade request information includes information indicating that the mobile phone 2 is displaying a map, the current position is calculated using the position detector 16 and the map data stored in the storage device 15 is used. The map is read out and a map around the current position is displayed on the display device 14.

  As a result, the map around the current position is displayed on the large screen using standard map data instead of simple map data with better position detection accuracy than when displaying a map around the current position on the mobile phone 2. It becomes possible to do.

  When the control unit 21 of the mobile phone 2 makes a function upgrade request in S216, it next confirms completion of the upgrade request function (S218). Specifically, the control circuit 17 of the navigation device 1 is inquired as to whether or not the portable function substitution process is normally performed, and confirms whether or not the portable function substitution process is normally performed.

  Here, when the mobile function substitution process is normally performed by the control circuit 17, the determination in S218 is YES, and then the function upgrade by the navigation device 1 is completed, and the display unit of the mobile phone 2 and Playback of the video output from the speaker is stopped, and this process is terminated.

  When the portable function replacement process is not normally performed by the control circuit 17, the determination in S218 is NO, the process returns to S212, and a function upgrade request is made again in S216.

  Further, the control circuit 17 of the navigation device 1 determines whether or not the navigation device 1 has been stopped (S120). Specifically, it is determined whether or not the ignition switch is turned off in accordance with the user's operation and the navigation device 1 is in a stopped state.

  In a state where the ignition switch is kept on, the determination in S120 is NO, and the portable function substitution process in S118 is continued. When the ignition switch is turned off and the vehicle is stopped, the determination in S120 is YES, and the portable function replacement process in S118 is stopped and information indicating the device status at the time of stop is transmitted to the mobile phone 2 (S122). For example, if music video video playback is in progress, the fact that music video video playback has been stopped is transmitted to the mobile phone 2, and if map display is in progress, the mobile phone indicates that map display has been stopped. Transmission to the telephone 2 is completed.

  Although not shown in the figure, the control unit 21 of the mobile phone 2 turns off the ignition switch, the navigation device 1 is stopped, and the control circuit 17 of the navigation device 1 receives information indicating the device status at the time of stoppage. If received, a message indicating that the upgrade by the navigation device 1 has been interrupted is displayed on the display unit, and this process is terminated.

  Further, when the user does not select the changeover switch on the confirmation screen as to whether or not the navigation device 1 upgrades the function of the mobile phone 2 displayed on the display screen of the display device 14 in S212. The determination in S214 is NO, and the process proceeds to S218 without making a function upgrade request.

  According to the configuration described above, the control circuit 17 of the navigation device 1 compares the function specification overlapping the function of the mobile phone 2 with the function specification of the mobile device 2, and determines the function of the mobile phone 2. When it is confirmed that the function is upgraded when it is implemented with the function that overlaps with the mobile phone 2, the function that overlaps with the mobile phone 2 is implemented instead of the mobile phone 2. Functions can be implemented instead.

  In addition, the control unit 21 of the mobile phone 2 compares the specification of the function of the navigation device 1 with the specification of the function that overlaps with the navigation device 1, and implements the function that overlaps with the navigation device 1 by the function of the navigation device 1. If it is confirmed whether or not the function is upgraded, and it is confirmed that the function is upgraded when the function overlapping with the navigation device 1 is implemented by the function of the navigation device 1, then the mobile phone 2 is replaced. Since the request is made with the function of the navigation device 1, it is possible to replace the function of the mobile phone 2 with a higher grade than the mobile phone 2.

  Further, the control unit 21 of the mobile phone 2 confirms with the user whether or not to implement the function of the navigation device 1 instead of the function overlapping with the navigation device 1, and replaces the function overlapping with the navigation device 1. When it is confirmed that the operation is performed with the function 1, the navigation apparatus 1 is requested to perform the function with the function of the navigation apparatus 1 instead of the function overlapping with the navigation apparatus 1. It can be requested that the function of the navigation device 1 be performed instead of the function that overlaps with the function.
