And a display unit such as a panel unit 14. Moreover, as shown to FIG. 6A of patent document 1, the front panel unit 14 or a display part has the navigation microcomputer 14m or a microcomputer, and according to description of the paragraph [0043] of patent document 1, the navigation microcomputer 14m is For example, the processing capability is several times that of the system microcomputer 10i of FIG. 6A or the cradle microcomputer 12b of FIG. 6B.

Japanese Patent No. 4376294

  Generally, if the amount of heat generated by the navigation microcomputer 14m is determined according to the processing capability of the navigation microcomputer 14m, and the amount of heat generated by the navigation microcomputer 14m increases, the navigation microcomputer 14m may not operate normally. Accordingly, the front panel unit 14 or the display unit having the navigation microcomputer 14m can have a cooling fan for cooling the navigation microcomputer 14m, but in this case, the front panel unit 14 or the display unit is enlarged. Alternatively, the front panel unit 14 or the display unit can have a heat dissipation structure instead of the cooling fan, and the small front panel unit 14 or the display unit can be formed by dissipating heat from the front panel unit 14 or the entire display unit. Can be provided.

  On the other hand, the in-vehicle device such as the front panel unit 14 preferably operates normally even in a harsh environment, and preferably generates less heat from the navigation microcomputer 14m or the front panel unit 14. In particular, according to the contents of FIGS. 1 and 2 of Patent Document 1, for example, when the front panel unit 14 is mounted on the base unit 10 or the cradle unit 12, the back surface of the front panel unit 14 and the base unit 10 or the cradle unit 12 are used. The present inventor has recognized that there is little gap with the front surface of the computer and heat from the navigation microcomputer 14m is trapped in the gap.

  One object of the present invention is to provide an in-vehicle device that can operate normally even in a harsh environment. Other objects of the present invention will become apparent to those skilled in the art by referring to the aspects and preferred embodiments exemplified below and the accompanying drawings.

  In the following, in order to easily understand the outline of the present invention, embodiments according to the present invention will be exemplified.

A first aspect according to the present invention includes a base portion provided in a vehicle,
A tablet terminal detachably provided on the base part;
With
The number of applications that can be executed on the tablet type terminal when the tablet type terminal is mounted on the base unit is executed on the tablet type terminal when the tablet type terminal is detached from the base unit. It relates to an in-vehicle device characterized by being lower than the number of possible applications.

  According to this in-vehicle device, the number of applications that can be executed when the tablet type terminal is mounted on the base unit (in-vehicle) is set low. Therefore, the heat generation from the processing unit or the tablet terminal when in-vehicle is set to be small. As a result, the in-vehicle device can operate normally even in a harsh environment. In other words, by reducing the amount of heat generated when in-vehicle, it is possible to prevent the in-vehicle device from operating normally, or to set a longer period during which the in-vehicle device operates normally. Improves.

In the first aspect, when the tablet terminal is attached to the base unit, the tablet terminal may be able to start a launcher application,
The launcher application may be capable of registering the application that can be executed on the tablet terminal when the tablet terminal is mounted on the base unit within a registration upper limit number.

  By providing the registration upper limit number (predetermined upper limit value) in the launcher application, the number of applications registered in the launcher application can be limited. Such a limitation limits the number of applications that can be executed simultaneously, and also limits heat generation from the processing unit or the tablet terminal when in-vehicle.

In the first aspect, the launcher application may be capable of starting at least one first application registered as the application in the launcher application,
When the at least one first application is executed during traveling, the launcher application may stop the at least one first application.

  By stopping the first application, the driver can concentrate on driving the vehicle, and the vehicle can travel safely. In addition, by stopping the first application, heat generation from the processing unit or the tablet terminal at the time of vehicle mounting is set to be further reduced.

In the first aspect, the launcher application may be registered as the application in the launcher application and be capable of starting at least one second application suitable for the traveling,
If the at least one second application is being executed during the travel, the launcher application may continue to execute the at least one second application.

  With the second application suitable for traveling, the driver can concentrate on driving the vehicle, and the vehicle can travel safely.

In the first aspect, the tablet type terminal may automatically start the launcher application with a predetermined timing as a trigger,
The predetermined timing may be a time when the tablet type terminal detects that the tablet type terminal is mounted on the base unit.

  As a predetermined timing, the launcher application is automatically started with a trigger when the tablet type terminal detects that the tablet type terminal is mounted on the base unit. As a result, the launcher application is more reliably activated when the vehicle is mounted, and the heat generation from the processing unit or the tablet terminal when mounted is more reliably set to be small.

  In the first aspect, when the tablet type terminal is mounted on the base unit, the tablet type terminal may prioritize camera display of a camera provided in the vehicle over the launcher application.

  Prioritizing the camera display, the driver can concentrate on driving the vehicle, and the vehicle can travel safely.

  Those skilled in the art will readily understand that the illustrated embodiments according to the present invention can be further modified without departing from the spirit of the present invention.

The example of a transition of the operation state of a tablet-type terminal is shown. The example which a tablet-type terminal and a base part cooperate is shown.

  The preferred embodiments described below are used to facilitate an understanding of the present invention. Accordingly, those skilled in the art should note that the present invention is not unduly limited by the embodiments described below.

  FIG. 1 shows a schematic configuration example of a system including an in-vehicle device according to the present invention. In the example of FIG. 1, the in-vehicle device includes a base portion 4 provided in a vehicle such as an automobile, and a tablet terminal 1 that can be attached to and detached from the base portion. In addition, the tablet terminal 1 has a built-in processing unit and can execute various applications or programs. For example, the cradle unit 12 shown in FIG. 3 of Patent Document 1 is attached to, for example, the upper part or the surface of the dashboard as shown in FIG. Alternatively, the base portion 4 can be provided on the vehicle body of the vehicle via a dashboard, for example.

  In the example of FIG. 1, the tablet terminal 1 does not have a communication unit such as a 3G communication module that can be connected to a line 3 configured by the Internet, for example. Therefore, by connecting the tablet terminal 1 to the terminal 5 that can be connected to the line 3, for example, various applications or programs set to be downloadable on the server 2 are taken into the tablet terminal 1. Various applications include, for example, a navigation application that guides a vehicle to a destination by a travel route. In this way, the in-vehicle device can be constructed as a navigation device, for example.

  The base unit 4 includes, for example, a connection unit such as a connection interface that connects the base unit 4 and the tablet terminal 1, a driving power source for the tablet terminal 1, and a power source unit that generates a driving power source for components in the base unit 4. Is done. The base unit 4 does not need to have a processing unit such as a CPU (central processing unit), but may have a processing unit. In the example of FIG. 1, the base portion 4 has, for example, a convex female pin terminal as a connection interface on the front surface of the base portion 4, and the female pin terminal is, for example, a concave shape provided on the back surface of the tablet terminal 1. It fits with a male pin terminal (not shown), and the connecting portion also functions as an attaching / detaching portion. For the concave male pin terminal, for example, a connector 14z or a connection interface as shown in FIGS. 2 and 6A of Patent Document 1 can be adopted.

  In the example of FIG. 1, when the tablet terminal 1 is attached to the base part 4, the recesses (including the convex female pin terminal) provided on the front surface of the base part 4 are also formed on the back surface of the tablet terminal 1. It fits with the provided convex part (not shown), there is little gap between the front surface of the base part 4 and the back surface of the tablet terminal 1, and the front surface of the base part 4 is almost in close contact with the back surface of the tablet terminal 1. ing. As the convex portion provided on the back surface of the tablet terminal 1, for example, a convex portion including a catch lever 14h and a fixed claw 14g as shown in FIG.

  For example, an in-vehicle battery installed in a room storing a prime mover of a vehicle or an engine room of an automobile is connected to the power source of the base unit 4. The in-vehicle battery supplies the in-vehicle battery power to the power source. The power source unit converts, for example, an in-vehicle battery power source (for example, 12 [V]) into a driving power source (for example, 5 [V]) of the tablet terminal 1 and, for example, via a convex female pin terminal of the base unit 4. Can be supplied to the tablet-type terminal 1.

  Here, the power supply unit of the base unit 4 may always use the in-vehicle battery power source, or may use the in-vehicle battery power source when the accessory switch is turned on, for example. In other words, the power supply unit of the base unit 4 may convert the in-vehicle battery power source (for example, 12 [V]) as a constant power source into the driving power source (for example, 5 [V]) of the tablet terminal 1 as it is, The in-vehicle battery power source (for example, 12 [V]) may be converted into the driving power source (for example, 5 [V]) of the tablet terminal 1 via a relay switch (not shown), for example. The relay switch connects the in-vehicle battery power source to the power source unit of the base unit 4 when the accessory switch is turned on. For example, the in-vehicle battery power source is connected to the power source of the base unit 4 when the engine switch or the ignition switch is turned on. You may connect to a part.

  The tablet terminal 1 includes, for example, a processing unit such as a CPU, a storage unit such as an HDD (hard disk drive) and a flash memory, a connection unit such as a connection interface for connecting the base unit 4 and the tablet terminal 1, a tablet terminal It comprises a power supply unit that generates drive power for one component, a display unit such as a touch panel display, and an input unit. The storage unit or the tablet terminal 1 can store programs such as an OS (operating system) application and an application executable on the OS application. The OS is, for example, an Android OS, and can be executed when the tablet terminal 1 is mounted on the base unit 4 by detecting that the tablet terminal 1 is mounted on the base unit 4. Includes programs that limit the number of sensitive applications. The tablet terminal 1 is, for example, a tablet PC (personal computer), but may be a tablet microcomputer, for example.

  As described above, the connection portion of the tablet terminal 1 is, for example, a pin terminal of a concave male pin terminal, and the pin terminal of the tablet terminal 1 is fitted with, for example, the pin terminal of the base portion 4, It can also function as a detachable part. Further, for example, a pin terminal of the tablet terminal 1 can have a driving power terminal (terminal 1 side) of the tablet terminal 1, and when the tablet terminal 1 is attached to the base unit 4, The drive power supply terminal (terminal 1 side) is electrically connected to the drive power supply terminal (base part 4 side) of the tablet terminal 1. The driving power for the tablet terminal 1 generated by the base unit 4 is supplied to the tablet terminal 1 via the pin terminal (or driving power terminal) of the base unit 4 and the pin terminal (or driving power terminal) of the tablet terminal 1. Is supplied to the power supply unit.

  When the tablet terminal 1 is mounted on the base unit 4, the power supply unit of the tablet terminal 1 may supply the drive power from the base unit 4 to the component as it is in accordance with the standard of the component of the tablet terminal 1. Alternatively, the drive power supply may be converted into the drive power supply for the component and the converted power supply (drive power supply for the component) may be supplied to the component. In addition, a built-in battery (a battery on the terminal 1 side) is connected to the power supply unit of the tablet terminal 1, and the power supply unit of the tablet terminal 1 can charge the built-in battery with the driving power from the base unit 4. it can.

  When the tablet terminal 1 is detached from the base unit 4, the power supply unit of the tablet terminal 1 may supply the internal battery power from the internal battery as it is to the component, or use the internal battery power for the component. The power source converted into the driving power source (the driving power source for the component) may be supplied to the component.

  The server 2 includes a processing unit such as a CPU, a storage unit such as an HDD, and a communication unit such as an Ethernet (registered trademark) LAN (local area network) board. The storage unit or the server 2 can store an OS application and a program such as an application executable on the OS application. The OS is, for example, Windows (registered trademark) Server 2008 operating system, and the program includes, for example, a program that causes the terminal 5 to download an application that can be installed on the tablet terminal 1. The terminal 5 downloads the application on the server 2 to the terminal 5 and transfers the application to the tablet terminal 1. At this time, the terminal 5 may set the download destination to the tablet terminal 1 and execute download and transfer simultaneously. In other words, the tablet terminal 1 may download the application via the terminal 5.

  The terminal 5 includes, for example, a processing unit such as a CPU, a storage unit such as an HDD and a flash memory, and a communication unit such as an Ethernet (registered trademark) LAN board. In order to transfer the application by connecting the terminal 5 and the tablet terminal 1, the communication unit may further include a wired communication module such as a USB (Universal Serial Bus) communication module. You may further have wireless communication modules, such as a wireless fidelity) communication module and a Bluetooth (trademark) communication module. The storage unit or the terminal 5 can store an OS application and a program such as an application executable on the OS application. The OS is, for example, Windows (registered trademark) 7 operating system, and the program includes, for example, a program that communicates with the server 2 and the tablet terminal 1. The terminal 5 is, for example, a desktop PC, but may be a notebook PC, for example.

  FIG. 2 shows an operation example of the tablet terminal 1. In the example of FIG. 2, the number of applications that can be executed when the tablet terminal 1 is mounted on the base unit 4 of FIG. 1 (in-vehicle) is limited, while the number of applications that can be executed is Not limited. Specifically, for example, a launcher application is activated when the vehicle is mounted, and a registration upper limit number (predetermined upper limit value) is provided in the launcher application.

  In the example of FIG. 2, the launcher application is, for example, a tab-type launcher application (tab launcher application). For example, three types of tabs or main tabs (“setting tab”, “OTHER tab”, and “DRIVE tab”) Among them, “OTHER tab” or “OTHER main tab” is shown. The “OTHER tab” includes, for example, a mail application that can send and receive e-mail, an A application that can execute a specific purpose, a B application that can execute another specific purpose, such as a weather application that can obtain weather information of a predetermined area For example, a calendar application capable of displaying a calendar in which a schedule can be incorporated, a video application capable of reproducing a video on the Internet, and a search application capable of searching various information such as information on a destination are registered, and a tab launcher For example, seven icons of applications registered in the application are shown.

  As will be described later, the “OTHER tab” includes, for example, two sub tabs of “A tab” and “B tab”, and the “OTHER tab” (main tab) as a whole is, for example, 7 × 2 = 14 pieces. An icon or application can be registered. In other words, of the registration upper limit number (predetermined upper limit value), the OTHER tab registration upper limit number related to the “OTHER tab” is set to 14, for example, and the tab launcher application registers 15 or more applications in the “OTHER tab”. It is not possible. Thus, the number of applications that can be executed when the tablet terminal 1 is mounted on the base unit 4 is set low. Therefore, heat generation from the CPU or the tablet terminal 1 in the vehicle is set to be small. As a result, the in-vehicle device can operate normally even in a harsh environment. In other words, it is possible to prevent the tablet terminal 1 from operating normally by reducing heat generation when the vehicle is mounted, or to set a longer period for the tablet terminal 1 to operate normally. 1 or the durability and reliability of the in-vehicle device are improved.

  The tab launcher application is preferably started automatically with a predetermined timing as a trigger. Here, the tablet terminal 1 detects that the tablet terminal 1 is mounted on the base unit 4, for example. By setting when the vehicle is mounted, the launcher application is more reliably activated when the vehicle is mounted, and the heat generation from the processing unit or the tablet terminal 1 when being mounted is more reliably set to be small.

  For example, the power supply unit or CPU of the tablet terminal 1 can always determine or monitor whether or not the tablet terminal 1 is detached from the base unit 4. Specifically, for example, the power supply unit or the CPU determines whether or not the connection interface or pin terminal of the tablet terminal 1 and the connection interface or pin terminal of the base unit 4 are connected.

  More specifically, for example, when both side terminals of the pin terminal of the base portion 4 are grounded to the vehicle body and set to the ground potential, for example, both side terminals of the pin terminal of the tablet terminal 1 are the pins of the base portion 4. When, for example, both terminals of the terminal of the terminal of the tablet terminal 1 are connected to the ground potential and the terminal is set to the ground potential, for example, the power supply unit or the CPU is not detached from the base 4 of the tablet terminal 1. That is, it is determined that the tablet terminal 1 is attached to the base unit 4. In other words, for example, the power supply unit or the CPU can monitor the potentials of both side terminals of the pin terminal of the tablet terminal 1 and determine whether both of the potentials are floating or ground.

  For example, the power supply unit or the CPU may monitor the potential of the driving power supply terminal of the pin terminal of the tablet terminal 1 and determine whether the potential is floating or, for example, 5 [V]. Alternatively, when the base unit 4 has a CPU, for example, and the connection state between the tablet terminal 1 and the base unit 4 is monitored by the power unit or CPU of the base unit 4, for example, the power unit or The CPU may receive a monitoring result on the base unit 4 side at, for example, a communication terminal of the pin terminal of the tablet terminal 1 and determine or monitor whether or not the tablet terminal 1 side is removed from the base unit 4. . Here, when the potential of the drive power supply terminal of the pin terminal of the tablet terminal 1 is set to, for example, 5 [V], the base unit 4 converts the 5 [V] to the accessory power supply (for example, the relay switch from the vehicle battery power supply). May be generated from an always-on power source (on-vehicle battery power source itself).

  As described above, when the tablet terminal 1 detects that the tablet terminal 1 is mounted on the base unit 4, specifically, the connection interface of the tablet terminal 1 is connected to the connection interface of the base unit 4. This is the time when the tablet terminal 1 detects that it is connected. More specifically, for example, the tablet indicates that the drive power of the tablet terminal 1 is supplied from the base unit 4 to the tablet terminal 1. When the tablet terminal 1 detects that the ground potential is being supplied from the base unit 4 to the tablet terminal 1 or when the monitoring result indicating the connection state is detected from the base unit 4 to the tablet. This is the time when it is detected by the tablet terminal 1 that it is supplied to the terminal 1.

  At the moment when, for example, the power supply unit or CPU of the tablet terminal 1 detects that the tablet terminal 1 is attached to the base unit 4, the tablet terminal 1 automatically activates the tab launcher application. In addition, at the moment when, for example, the power supply unit or CPU of the tablet terminal 1 detects that the tablet terminal 1 has been removed from the base unit 4, the tablet terminal 1 stops the tab launcher application.

  By the way, the tablet-type terminal 1 at the time of removal can install various applications. In the example of FIG. 2, the display unit of the tablet terminal 1 or a touch panel display, for example, represents a home screen of an Android OS, for example, and a folder for storing icons of various applications or a plurality of icons on the home screen. Existing. Further, for example, the above-described search application is executed, and widgets also exist on the home screen. Strictly speaking, the number of applications that can be executed when the tablet-type terminal 1 is detached from the base unit 4 is strictly limited by the storage unit or hardware of the tablet-type terminal 1. The capacity may be ignored, and the number of executable applications or applications that can be installed in the tablet terminal 1 is not substantially limited. Therefore, for example, the driver or the user can freely select and operate the application at the time of removal.

  However, depending on the type of application, there are applications that are not suitable when the vehicle is traveling. Examples of the application that is not suitable for traveling or that does not correspond to the predetermined recommended application include the above-described moving image application. By restricting the use of such applications to when the tablet terminal 1 is mounted on the base unit 4 (in-vehicle), the driver can concentrate on driving the vehicle, and the vehicle travels safely. be able to. Note that the tablet-type terminal 1 can consider using the vehicle-mounted time as traveling, and can restrict the use of a video application, for example. However, preferably, the tablet-type terminal 1 actually uses the base unit 4 when traveling. For example, the use of the moving image application is restricted according to the determination result. Here, an application that does not correspond to the predetermined recommended application is registered in the “OTHER tab” of the tab launcher application, so that, for example, a moving image application can be used when the vehicle is mounted, preferably when the vehicle is mounted and when it is not running. .

  The tab launcher application determines whether or not various applications held in the tablet terminal 1 correspond to a predetermined recommended application, and those applications that do not correspond to the predetermined recommended application are classified as applications belonging to the first group. can do. Applications corresponding to the predetermined recommended application are classified as applications belonging to the second group. The tablet terminal 1 has at least one application (first application) as an application belonging to the first group, and at least one application (second application) as an application belonging to the second group. Can have. The driver or the user can register an application that does not correspond to the predetermined recommended application (application belonging to the first group) in the “OTHER tab” as a registration application that can be used when the vehicle is mounted and not running, for example. . An application corresponding to a predetermined recommended application (an application belonging to the second group) is, for example, registered in the “DRIVE tab” as a registered application that can be used both when traveling and when traveling and when traveling and not traveling. You can register.

  When a registered application registered in the “OTHER tab” (for example, the above-described moving image application) is activated when the vehicle is on-board and is not running, and the non-running time changes during running while the registered application is being executed. The tab launcher application can stop its registered application. By stopping a registered application (for example, the above-described moving image application) registered in the “OTHER tab” during traveling, the driver can concentrate on driving the vehicle, and the vehicle can travel safely. Further, by stopping the registered application registered in the “OTHER tab” during traveling, the heat generation from the processing unit or the tablet terminal 1 in the vehicle is set to be further reduced.

  When a registration application (for example, a navigation application described later) registered in the “DRIVE tab” is activated when the vehicle is in-vehicle and not running, and the non-running time changes during running while the registered application is being executed. The tab launcher application can continue to execute its registration application. Even if a registration application (for example, a navigation application described later) registered in the “DRIVE tab” is executed during traveling, the driver can concentrate on driving the vehicle, and the vehicle can travel safely.

  FIG. 3 shows an example of selecting a main tab or a sub tab. For example, when the vehicle is in-vehicle and not running, the tab launcher application is activated. For example, when “OTHER tab” is selected, for example, the upper tab screen in FIG. 2 or the upper right tab screen in FIG. 3 is displayed. For example, as described above, seven icons are shown. The driver can freely select the main tab or the sub tab when the vehicle is on-board and not running, and when the driver selects the “DRIVE tab” displayed on the touch panel display, for example, by hand, for example, FIG. Is switched from the tab screen on the upper right side of FIG. 3 to the tab screen on the upper left side of FIG. 3 (see arrow S2 in FIG. 3). Here, for example, by selecting with the “HOME” button of the tablet terminal 1, for example, the tab screen on the upper right side in FIG. 3 is switched to the tab screen on the upper left side in FIG. 3 (see arrow S <b> 2).

  In the example of FIG. 3, the “DRIVE tab” includes a navigation application, for example, a music application that can play music media, such as a TV application that can receive TV, for example, a radio application that can receive FM and AM radio, such as Bluetooth ( (Registered trademark) Bluetooth (registered trademark) AUDIO application capable of outputting the sound of another device to be linked, for example, a cellular phone application capable of hands-free operation of the cellular phone terminal 6 described later, for example, HDMI (High Definition Multimedia Interface) standard VICS (registered trademark) (foundation road traffic) that can display information such as characters and figures by obtaining road traffic information such as traffic jams and traffic regulations, for example, an HDMI application that can input a signal of the following from an HDD player 9 to be described later Information communication system Temu Center) application, and for example, highways on the road traffic information can receive highway radio flowing traffic information application is registered, the tab launcher application of registered applications for example nine icons are shown.

  For example, nine icons or applications can be registered in the “DRIVE tab”. In other words, among the registration upper limit number (predetermined upper limit value), the DRIVE tab registration upper limit number related to the “DRIVE tab” is set to 9, for example, and the tab launcher application registers 10 or more applications in the “DRIVE tab”. It is not possible. Thus, the number of applications that can be executed when the tablet terminal 1 is mounted on the base unit 4 is set low. Therefore, heat generation from the CPU or the tablet terminal 1 in the vehicle is set to be small. Also, by setting the DRIVE tab registration upper limit number smaller than the OTHER tab registration upper limit number, it becomes possible to reduce the heat generation when the vehicle is mounted during traveling. Thereby, the reliability of the tablet-type terminal 1 at the time of driving | running | working further improves.

  The application that can be registered in the “DRIVE tab” is, for example, an application in which the driver does not watch the display unit of the tablet terminal 1 during traveling. The television application displays a television screen on, for example, a touch panel display of the tablet-type terminal 1 when not running, but outputs only the television sound when traveling without outputting the television screen when traveling. Further, the navigation application can set the destination when not traveling, but cannot set the destination when traveling. Further, the music application displays, for example, the title of the next song when not running, but does not display the title of the next song when running. In this way, an application that can be registered in the “DRIVE tab” can operate a travel restriction that restricts a predetermined function during traveling, and can release the travel restriction when not traveling.

  In the example of FIG. 3, for example, when the driver selects the “OTHER tab”, for example, the tab screen on the upper left side of FIG. 3 is switched to the tab screen on the upper right side of FIG. 3 (see arrow S1). Next, for example, when the driver selects “B tab” in the “OTHER tab”, for example, the tab screen on the upper right side in FIG. 3 is switched to the tab screen on the lower right side in FIG. 3 (see arrow SB). In the example of FIG. 3, a calculation application that can execute calculations such as addition, subtraction, multiplication, and division is registered in the “B tab” of the “OTHER tab”, and for example, 1 of the applications registered in the tab launcher application. Two icons are shown. For example, six icons or applications can be additionally registered in the “B tab” of the “OTHER tab”.

  In the example of FIG. 3, for example, when the driver selects the “setting tab”, for example, the tab screen on the lower right side of FIG. 3 is switched to the tab screen on the lower left side of FIG. 3 (see arrow S4). In the “setting tab”, an application cannot be registered by the driver or the user, and a predetermined application is fixed. In the example of FIG. 3, the “setting tab” includes, for example, an OTHER mode application registration application that registers an application in the “OTHER tab”, a HELP application that explains how to use the tab launcher application, and a guide line of a rear camera provided in the vehicle. Rear camera setting application to be adjusted, for example, a WI-FI setting application for enabling or disabling the Wifi communication module of the tablet terminal 1, for example, a speaker and microphone of the tablet terminal 1 or an in-vehicle speaker (not shown) and an in-vehicle microphone (see FIG. AUDIO setting application for selecting (not shown), for example, Bluetooth (registered trademark) setting application for enabling or disabling Bluetooth (registered trademark) of the tablet terminal 1, and other functions for setting other functions, for example The setting application is fixed, and for example, seven icons of the application fixed to the tab launcher application are shown.

  In the tab launcher application, for example, a clock application that can display the current time is also fixed, and with the execution of the tab launcher application, the clock application is also always executed, regardless of the selection of the main tab or sub tab. For example, “22:36” is shown as the time.

  In the example of FIG. 3, for example, when the driver selects the “DRIVE tab” or “HOME” button, for example, the tab screen on the lower left side of FIG. 3 is switched to the tab screen on the upper left side of FIG. 3 (see arrow SH). . Next, for example, when the driver selects “setting tab”, for example, the tab screen on the upper left side in FIG. 3 is switched to the tab screen on the lower left side in FIG. 3 (see arrow SS). Next, for example, when the driver selects the “OTHER tab”, for example, the tab screen on the lower left side of FIG. 3 is switched to the tab screen on the lower right side of FIG. 3 (see arrow S3). Next, for example, when the driver selects “A tab” in the “OTHER tab”, for example, the tab screen on the lower right side in FIG. 3 is switched to the tab screen on the upper right side in FIG. 3 (see arrow SA).

  FIG. 4 shows a display example of the display unit of the tablet terminal 1. In the example of FIG. 4, the tablet terminal 1 may have a sleep function. When the sleep function is executed or when the power of the tablet terminal 1 is turned off, the display unit of the tablet terminal 1 is Turns off. In the example of FIG. 4, for example, when the driver turns on the accessory switch and the tablet terminal 1 is attached to the base unit 4 in a state where the display unit is turned off, for example, from the left upper screen of FIG. 4 is switched to the startup screen on the upper right side (see arrow S5 in FIG. 4). Until the tab launcher application starts up, for example, an image representing the system name of the tab launcher application is displayed on the startup screen. In the example of FIG. 4, for example, when the tab launcher application is executed in the DRIVE mode, for example, the startup screen on the upper right side in FIG. 4 is switched to the execution screen on the lower right side in FIG. 4 (see arrow S6).

  In the example of FIG. 4, the execution screen is controlled by a tab launcher application. For example, the execution screen includes an area (application area) for displaying an application icon registered in the tab launcher application. The execution screen (application area) also includes an area (selection tab area) for selecting, for example, three types of tabs or main tabs.

  For example, when the driver turns off the accessory switch in the state of the execution screen, for example, the execution screen on the lower right side in FIG. 4 is switched to the unlit screen on the upper left side in FIG. 4 (see arrow S7), while the tablet terminal 1 is changed. When removed from the base unit 4, for example, the execution screen on the lower right side in FIG. 4 is switched to the terminal screen on the lower left side in FIG. 4 (see arrow S8). Next, for example, when the driver wears the tablet terminal 1 on the base unit 4 in the state of the terminal screen, for example, the terminal screen on the lower left side in FIG. 4 switches to the startup screen on the upper right side in FIG. 4 (see arrow S9). ).

  In the example of FIG. 4, the terminal screen is controlled by the Android OS. For example, the terminal screen includes a home screen that displays an application icon held by the tablet terminal 1. When an application is activated and executed from the home screen, the terminal screen includes a screen controlled by the application.

  In the example of FIG. 4, for example, whether or not an accessory switch, an engine switch, or the like is turned on or off, or whether or not the drive power source (for example, 5 [V]) of the tablet terminal 1 is supplied from the base unit 4 It also functions as a command to turn on / off the power button or start and stop the tab launcher application.

  FIG. 5 shows a transition example of the operation state of the tablet terminal 1. In the example of FIG. 5, when the tablet terminal 1 is displaying the home screen of the Android OS, for example, when the tablet terminal 1 is removed from the base unit 4, for example, the driver holds the tablet terminal 1. If no operation is performed for a certain time, the tablet terminal 1 executes the sleep function (see arrow S10 in FIG. 5). At this time, the tablet terminal 1 turns off the display unit of the tablet terminal 1. If the driver touches the touch panel display, for example, when the tablet terminal 1 is executing the sleep function, the tablet terminal 1 stops the sleep function and, for example, the home screen is displayed again (arrow S12). reference). When the power button of the tablet terminal 1 is turned off or the remaining amount of the built-in battery of the tablet terminal 1 becomes equal to or less than the specified value, the tablet terminal 1 executes shutdown of the Android OS (see arrow S11).

  For example, when the tablet terminal 1 is attached to the base unit 4 in a state where the accessory switch or the engine switch is turned off, the operation state of the tablet terminal 1 does not change (see arrows S13, S19, S22). In the example of FIG. 5, even when the tablet terminal 1 is mounted on the base unit 4, for example, if the driver does not operate the tablet terminal 1 for a certain period of time, the tablet terminal 1 executes the sleep function (arrow) (See S16). If the driver touches the power button, for example, when the tablet terminal 1 is executing the sleep function, the home screen is displayed again (see arrow S18). When the tablet terminal 1 is executing the sleep function, for example, if the driver does not operate the tablet terminal 1 for 10 minutes, for example, or the remaining battery charge of the tablet terminal 1 becomes equal to or less than a specified value, the tablet terminal 1 Performs a shutdown (see arrow S17).

  For example, when the accessory switch or the engine switch is turned on and the tablet terminal 1 displaying the Android OS home screen or in the sleep state is attached to the base unit 4, the tablet terminal 1 displays the tab launcher application. Until the tab launcher application starts up automatically, an opening screen such as an image representing the system name of the tab launcher application is displayed (see arrows S15 and S46). For example, when the Android OS is shut down, the tablet terminal 1 automatically starts the Android OS (see arrow S24), and automatically starts the tab launcher application (see arrow S25).

  For example, when the accessory terminal or the engine switch is turned on in a state where the tablet terminal 1 is mounted on the base unit 4, the tablet terminal 1 displaying the Android OS home screen or in the sleep state can display the tab launcher application. It starts automatically and displays, for example, an opening screen (see arrows S14 and S20). For example, when the Android OS is shut down, the tablet terminal 1 automatically starts the Android OS (see arrow S23).

  As described above, when the tablet terminal 1 is mounted on the base unit 4, for example, when the accessory switch is turned on, the tablet terminal 1 is based on the drive power (for example, 5 [V]) of the tablet terminal 1. It is possible to automatically start the tab launcher application by determining that it is supplied from the unit 4.

  In the state in which the tablet terminal 1 is mounted on the base unit 4, for example, at the moment when the accessory switch is turned off, the tablet terminal 1 has a driving power (for example, 5 [V]) of the tablet terminal 1 for example pinned. By determining that the terminal is not supplied from the base unit 4, the tab launcher application (and the registered application that is activated and executed from the tab launcher application) can be automatically stopped. The sleep function can be executed (see arrow S21). In the state where the tablet terminal 1 is attached to the base part 4, for example, at the moment when the tablet terminal 1 is removed from the base part 4, the tablet terminal 1 has a ground potential at the pin terminal, for example, at the base part 4. Therefore, the tablet launcher application can be automatically stopped and the tablet terminal 1 can display a home screen, for example (see arrow S47).

  In the example of FIG. 5, the tablet terminal 1 or the CPU starts a tab launcher application when the tablet terminal 1 or the Android OS is started, but displays a camera display such as a rear camera provided in the vehicle rather than the tab launcher application. Can be prioritized. Here, for example, a camera application that displays an image captured by a rear camera on a display unit such as a touch panel display is executed in the background, for example, and an image captured by, for example, the rear camera is always supplied from the base unit 4. It can be determined or monitored by, for example, a pin terminal (or a video terminal, for example). Note that the camera application may display a superimposed image in which, for example, a guide line is superimposed on an image captured by the rear camera. If the tablet terminal 1 has a sleep function, it is compared with shutdown of the OS. Then, the camera application at the time of sleep can be executed quickly.

  By the way, for example, when the driver moves or sets a shift device such as a shift lever to “R (reverse)”, the base unit 4 determines whether the backlight (reverse light), the reverse switch, etc. are on, An image captured by the camera can be supplied or transferred to the tablet terminal 1. For example, when the Android OS is started with the backlight turned on, the Android OS can start the camera application with priority over the tab launcher application, and the tablet terminal 1 is set immediately before, for example, It is possible to display the camera display in the state that has been displayed (see arrow S40 in FIG. 5). Note that the tablet terminal 1 is a tablet type until the Android OS and the camera application are started by executing or selecting the hardware (for example, the selector) with priority over the software (for example, the Android OS and the camera application). The terminal 1 may execute camera display that does not include a guide line, for example.

  In the example of FIG. 5, in a state where the backlight or the like is turned on, the camera application is executed in the foreground, and a superimposed image in which a button image that can change the field of view of the rear camera, for example, is superimposed on an image captured by the rear camera. An image is displayed. For example, when the user touches a “view” button (not shown) displayed on the display unit of the tablet-type terminal 1 or the superimposed image with the hand, the camera application displays a “normal” button representing a normal view, a wide view. Selection buttons (not shown) such as a “wide” button for representing and a “top-down” body for viewing from above can be displayed (see arrow S41). In the state where the selection button is displayed, for example, if the driver does not operate the tablet terminal 1 for 5 seconds, for example, the camera display in the state set immediately before is displayed (see arrow S42), while the selection button is displayed. When selected, the camera display in the newly set state is displayed (see arrow S43).

  In the example of FIG. 5, in the state where the shift device is not set to “R (reverse)”, for example, the Android OS or the camera application, or an application linked thereto, can start the tab launcher application (arrow S26). reference). The tab launcher application is executed in the foreground, for example, and can always determine or monitor whether or not the vehicle is running, for example, at a pin terminal (or video terminal, for example). For example, the base unit 4 supplies or transmits a vehicle speed signal to the tablet terminal 1, and the tab launcher application can determine whether the vehicle is traveling or not traveling based on the presence or absence of the vehicle speed signal. The base unit 4 may transmit, for example, a parking signal, and the tab launcher application may determine whether the vehicle is traveling or not traveling based on both the vehicle speed signal and the parking signal or only the parking signal.

  In the example of FIG. 5, the tab launcher application can execute a registered application registered in, for example, “OTHER tab”, “DRIVE tab”, or the like in accordance with an instruction from the driver when the vehicle is mounted and not running. . When the registration application that is not suitable for driving is being executed and the tab launcher application detects the driving of the vehicle, the tab launcher application restricts the use of the registration application so that only the registration application suitable for driving can be executed ( (See arrow S27). Specifically, when a registered application registered in the “OTHER tab” is executed during traveling, the tab launcher application stops the application. Alternatively, if a registered application registered in the “DRIVE tab” is being executed during travel, the tab launcher application continues to execute the application. However, even if the registered application is registered in the “DRIVE tab”, if it has a function that is not suitable for traveling, it is preferable to stop the function.

  By the way, the navigation application can be executed not on the tab launcher application but also on the home screen of the Android OS, for example. In other words, the driver can activate the navigation application in advance and set the destination when the vehicle is not on-vehicle. Note that the navigation application may guide the driver or the user to the destination by a walking route when the vehicle is not mounted on the vehicle.

  When the tab launcher application is not executed, that is, when the vehicle is not mounted on the vehicle, the destination on the travel route is set in the navigation application, and the driver then attaches the tablet terminal 1 to the base unit 4, the tab launcher application At the time of activation, the tab launcher application or the navigation application maintains its destination as it was set immediately before. For example, when the accessory switch is turned on, the navigation application can set the travel route using the destination and guide the vehicle (see arrow S29 in FIG. 5).

  The function to set the destination is a function that is not suitable for driving, and the navigation application sets another destination that is different from the destination set immediately before, for example, when in-vehicle and not driving. can do. For example, when it is determined that the vehicle is traveling based on a signal from the vehicle speed sensor, the navigation application can guide the vehicle with the function of setting the destination being stopped (see arrow S33). For example, when it is determined that the vehicle is not traveling based on a signal from the vehicle speed sensor, the navigation application can validate the function of setting the destination (see arrow S32).

  In the example of FIG. 5, when the navigation application guides the vehicle to the destination by the travel route, touching a “end guidance” button (not shown) displayed on the display unit of the tablet terminal 1 with the hand The application displays the current position of the vehicle, for example, and stops guidance such as voice guidance and right turn instruction (see arrow S35). When the vehicle reaches the destination or near the destination, the navigation application displays the current position of the vehicle, for example, and stops guidance (see arrow S35). Even when the navigation application displays the current position of the vehicle, for example, the function not suitable for traveling is stopped (see arrow S37), and the function can be used when not traveling (see arrow S36). When the navigation application displays the current position of the vehicle and touches a “guidance start” button (not shown) displayed on the display unit of the tablet terminal 1 with the hand, the navigation application resumes or starts guidance. (See arrow S34).

  In the example of FIG. 5, a “return” button (not shown) displayed on the display unit of the tablet terminal 1 or hardware provided on the tablet terminal 1 in a state where a registration application such as a navigation application is executed. When the “HOME” button (not shown) is touched by hand, the registered application continues to stop or execute in the background, and the tab launcher application can start another registered application (see arrow S31). When the registered application icon is selected and activated on the tab launcher application, the registered application can be executed. For example, a TV application other than the navigation application may be used as a non-traveling (stopped) operation when a parking signal indicates the operation of a parking brake (not shown) and the vehicle speed signal does not indicate movement of the vehicle. Audio can be output (see arrow S38). When the parking signal does not indicate the operation of a parking brake (not shown), or when the vehicle speed signal indicates the movement of the vehicle, the TV application outputs only the sound without outputting the video as the operation during driving. (See arrow S39). In addition, the music application can display the title of the next song as an operation when the vehicle is not running, for example, when the vehicle speed signal does not indicate the movement of the vehicle (see arrow S38), while the vehicle speed signal indicates the movement of the vehicle. Is not displayed as an operation during running (see arrow S39).

  In the example of FIG. 5, when a backlight or the like is turned on while a registration application such as a navigation application is executed, the registration application continues to stop or execute in the background, while the camera application executes in the foreground. (See arrow S45). After that, when the backlight or the like is turned off in a state in which the camera application is executed, the camera application continues to execute in the background, while the registered application that has been executed immediately before or is executed in the background is It is executed in the foreground (see arrow S44). At this time, the registered application can maintain the screen or state displayed when the registered application is stopped or moved to the background (see arrow S44).

  As described above, when the tablet terminal 1 is mounted on the base unit 4, for example, at the moment when the accessory switch is turned off, the tablet terminal 1 uses the tab launcher application or the registration application, for example, the sleep function. And can be stopped automatically. Thereafter, when the accessory switch is turned on again with the backlight or the like turned on, the camera application is preferentially activated (see arrow S40), and then when the backlight or the like is turned off, the tab launcher application or The registered application can maintain the screen or state displayed at the time of the stop or sleep (see arrow S44).
