Therefore, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims are not necessarily required to achieve the object of the present invention, but are described as constituting more preferable embodiments. The

  FIG. 1 shows a block diagram of an in-vehicle device 100 of the present embodiment. The in-vehicle device 100 includes a display unit 101, a speaker 102, an input unit 103, a storage unit 104, a GPS (Global Positioning System) 105, a communication unit 106, and a control unit 110.

  The display unit 101 is configured with a liquid crystal display or the like, and displays information to be provided to a vehicle occupant. The speaker 102 outputs various audio information. The input unit 103 is configured with a touch panel or the like installed on the display unit 101, and the user inputs for operating the in-vehicle device 100. For example, when the function executed by the in-vehicle device 100 is navigation for route guidance, the user can input a destination or a waypoint for route setting.

  The storage unit 104 includes a hard disk, a flash memory, and the like, and stores map data and data such as a setting mode correspondence table described later. The GPS 105 receives a signal from a GPS satellite, calculates the current position of the vehicle on which the in-vehicle device 100 is mounted, and supplies the calculated position to the control unit 110.

  The communication unit 106 is, for example, an IC chip and a program for establishing a wireless connection with a mobile phone 200 such as a smartphone owned by a vehicle occupant in accordance with a Bluetooth (registered trademark) communication standard. Information stored in the server is acquired and supplied to the control unit 110.

  The control unit 110 includes a CPU, and executes a program having a predetermined function stored in an internal ROM or RAM. For example, when the function to be executed is navigation for route guidance, the control unit 110 executes a navigation program. The control unit 110 accesses the storage unit 104, reads map data in the vicinity of the detected current position of the vehicle, and outputs the map data to the display unit 101. The destination or waypoint input from the input unit 103 is supplied to the control unit 110, and the control unit 110 reads out the map data stored in the storage unit 104 and searches for a route to the destination. Then, the route information is provided by outputting voice information for route guidance to the speaker 102 together with the map information outputted to the display unit 101.

  The in-vehicle device 100 functions as an AV (Audio Visual) device for reproducing the radio, a CD (Compact Disc), a DVD (Digital Versatile Disc), or the like in addition to the navigation function. . In that case, the control unit 110 executes a program for causing the in-vehicle device 100 to function as an AV device.

  Here, regarding the operation of the in-vehicle device 100, it is conceivable that the mode setting is changed to change the ease of use depending on whether an occupant familiar with the operation operates or an inexperienced occupant operates. In the former case, the detailed operation explanation can be omitted or the operation history so far can be stored and the menu hierarchy can be skipped (hereinafter referred to as “expert”). In the latter case, the usage is explained in detail to some extent, and settings that do not skip the hierarchy are easier to operate (hereinafter referred to as “beginners”).

  In addition, when the in-vehicle device 100 is functioning as an AV device, the preference for the sound quality or the like of the music to be played differs depending on the occupant. Furthermore, since the preferred color scheme for the screen of the display unit 101 of the in-vehicle device 100 varies depending on the occupant, it is more convenient for the occupant to automatically set the screen color scheme.

  These do not depend solely on the driver, but preferably change according to the combination of the passengers who ride in the car together. For example, it may be more convenient to divide the volume and equalizer settings depending on whether the passenger has children or not than who the driver is. It is conceivable to create a sound environment that makes it easy to sleep by lowering the volume or lowering the equalizer bass when there are children.

  In addition, menu settings, etc., if one person (for example, “husband”) is familiar with the operation, the operation can be advised if that person is included. It is also possible to do. Therefore, when “husband” is included in the occupant, “expert” may be set.

  In the in-vehicle device 100 of the present embodiment, these various setting items can be automatically set depending on the combination of passengers, such as when riding alone, when riding by two people, when riding in a family, etc. . The configuration and operation for realizing the function of the in-vehicle device 100 will be described in detail below.

  In FIG. 1, the control unit 110 includes a setting mode determination unit 111, a setting reflection unit 112, and a user setting change unit 113 as functional blocks.

  The setting mode determination unit 111 refers to the setting mode correspondence table stored in the storage unit 104 by the mobile phone 200 connected by the communication unit 106 and determines which setting mode should be selected and set. To do. A specific determination method of the setting mode determination unit 111 will be described later.

  The setting reflection unit 112 reflects the setting value on various setting items of the in-vehicle device 100 based on the result determined by the setting mode determination unit 111.

  The user setting change unit 113 is called when the user changes the setting of the in-vehicle device 100 by a touch operation or a voice operation (not shown) from the input unit 103 and is stored in the storage unit 104. Edit the correspondence table. A specific processing procedure of the user setting changing unit 113 will be described later.

  Next, an example of the setting mode correspondence table stored in the storage unit 104 will be described with reference to FIG.

  In FIG. 2, a mobile phone ID column 201 shows a combination of connected mobile phones. Here, four types of “husband”, “wife”, “child”, and “guest” are listed for easy understanding, but the storage unit 104 of the in-vehicle device 100 stores the phone number of the mobile phone of the passenger in the car. A numerical value or a character string that can identify a mobile phone is stored. Further, the number is not limited to four, and there may be a plurality of types. It is desirable that the mobile phone registered in the mobile phone ID column 201 can be separately registered from the history of the user connecting to the in-vehicle device 100 in the past.

  “Guest” represents a case where a specific mobile phone registered by the user (here, mobile phones other than “husband”, “wife”, and “child”) is connected. Each record stores a binary value indicating whether each mobile phone in the mobile phone ID column is connected or not connected. For example, the record on the first line indicates that only “husband” is in a connected state with a circle, and “wife”, “child”, and “guest” are in an unconnected state in blank. Yes.

  Next, each column of the setting mode column 202 represents various setting items for setting the in-vehicle device 100 for the combination of the mobile phone connection states indicated in the mobile phone ID column 201. First, in the “name” column, in order to make the setting mode easy to understand, the user can give a name to each setting mode. Next, in the “menu” column, the operation menu of the in-vehicle device 100 can be set to “expert” or “beginner” described above.

  For example, in the case of FIG. 2, when only “husband” who is the owner of the car is recognized as an occupant, it is set to “expert” because he is used to the operation. If other “wife”, “child” and “guest” are recognized as passengers, those who are not familiar with the operation may operate in the passenger seat, so it is set to “beginner”. ing.

  In the “Equalizer” column, an equalizer curve used for music playback can be individually set. In the “coloring” column, a character string such as a character string, a button, or a window background color that configures the screen can be selected from several setting values.

  The types of setting modes mentioned here are merely examples, and any combination of setting items and setting values that can be customized by the in-vehicle device 100 can be added to the setting mode correspondence table.

  Next, a specific processing procedure of the setting mode determination unit 111 will be described with reference to the flowchart of FIG.

  First, in step S <b> 301, the setting mode determination unit 111 detects all the mobile phones 200 currently connected to the in-vehicle device via the communication unit 106. Next, in step S302, the detected mobile phone ID is compared with the mobile phone ID column of each record in the setting mode correspondence table stored in the storage unit 104, and a record in which the combination of the mobile phone connection states matches is found. Search and determine if there is.

  In step S302, when the combination of the current connection states is in the setting mode correspondence table (Yes), the process proceeds to step S303, and the setting values of the various setting items of the records matched in step S302 are extracted and sent to the setting reflection unit 112. hand over. The setting reflection unit 112 sets the passed setting value in the user interface and ends the process.

  If the combination of the current connection states is not in the setting mode correspondence table in step S302 (No), the process proceeds to step S304, and a new record corresponding to the combination of the current mobile phone connection states is created in the setting mode correspondence table. To do. Here, each setting item in the setting mode is the current setting value.

  In step S 305, the setting mode correspondence table to which the newly created record is added is stored in the storage unit 104.

  In step S303, the setting mode value of the newly added record is passed to the setting reflection unit 112. The setting reflection unit 112 sets the passed setting value in the user interface and ends the process.

  Since the current setting mode is automatically added when the connection state of a new mobile phone is detected by the processing of steps S304 and S305, the user registration is performed when the same connection state is reproduced next time. The same setting mode can be reproduced without requiring any processing.

  Next, the processing procedure of the user setting changing unit 113 will be described with reference to the flowchart of FIG. First, in step S401, the user setting change unit 113 determines whether each setting of the user interface has been changed by the user. When it is determined that the change has not been made (No), the process is repeated until the determination result of step S401 becomes Yes.

  In step S401, when each setting of the user interface is changed by the user (Yes), the process proceeds to step S402, and the mobile phone currently connected to the in-vehicle device 100 is detected via the communication unit 106. Specifically, the connection state of the mobile phone is detected as a variable number of columns of the mobile phone ID described in FIG.

  In step S403, the detected mobile phone ID column is compared with the mobile phone ID column of each record in the setting mode correspondence table to search for a record that matches the combination of connection states of the mobile phones. If there is a new mobile phone connection, it is guaranteed that a corresponding record is newly created in the processing of S304 and S305 in FIG. 3, and therefore no corresponding record exists in this step. There is basically no situation (it is necessary to handle errors). Then, the user setting change unit 113 stores in the storage unit 104 a setting mode correspondence table in which the setting items for which the setting of the retrieved record has been changed are rewritten.

  Next, the process proceeds to step S <b> 404, and setting values of various setting items of the record searched in step S <b> 402 are passed to the setting reflection unit 112 to the setting reflection unit 112. The setting reflection unit 112 sets the passed setting value in the user interface and ends the process.

  As described above, the in-vehicle device according to the present invention automatically switches the setting according to the combination of the occupants, and thus has the effect of saving the trouble of switching, and is useful as an in-vehicle device such as a navigation device mounted on a car. is there.
