Japanese Unexamined Patent Publication No. 2015-116913

Some applications that can be executed on portable devices, such as business software and games, are not intended for use in vehicles, and some applications are intended for use in vehicles, such as car navigation systems. Some applications are suitable for use in vehicles, and the latter is considered to be used frequently in vehicles. Depending on the user, the same application may always be used in the vehicle, or the same application that was used last time in the vehicle may be desired to be used this time. However, in a conventional portable device, if the user does not perform a certain operation such as displaying the home screen and touching the icon of the target application, the user launches an application suitable for use in the vehicle or such. I couldn't switch to another application.

Further, the portable device is generally assumed to be used as a computer for general purpose purposes. Considering its use for general purposes, it is desirable to be able to perform a variety of input operations. Therefore, in these portable devices, input functions such as UI can be performed so that as many input operations as possible can be performed on the premise that the operation is handheld and relatively close to the eyes and / or the screen is gazed at. Is optimized. For example, in the handheld operation, it is assumed that the portable device is held by the left hand at a position about 20 cm from the eyes, the elbow of the left hand is bent, and the finger of the right hand touches the screen. On the other hand, assuming use in a vehicle, it is not appropriate to use the above input function as it is. When installed on a dashboard, etc., the distance between the user and the portable device is longer than when it is handheld, and the user must extend his elbow to the portable device installed on the dashboard, etc. It is difficult to perform detailed operations because it is installed in a position that does not interfere with the driving view, etc., and it shakes while driving, and when the user is driving. This is because it is not preferable for safety to operate while watching the screen. Therefore, it is desired to provide an appropriate input function according to the usage situations outside the vehicle and inside the vehicle.

The present application discloses inventions that address all or part of the above problems or other problems.

The present application discloses, for example, the inventions described in the following configuration examples.

<Structure example 1>
It is a portable device that can operate by power supply from multiple external power sources including vehicles and power supply from internal batteries, and can execute multiple applications.
Vehicle power supply judgment function that judges whether or not power is supplied from the vehicle,
When there is a first transition that is a transition from a state with power supply from the vehicle to a state without power supply from the vehicle, the last is a storage means for storing information indicating the application that was being executed at the time of the first transition. The last app memory function to be stored in the app storage means,
When there is a second transition, which is a transition from a state in which there is no power supply from the vehicle to a state in which there is power supply, it is characterized by having a last application activation function for activating the application indicated by information stored in the last application storage means. Portable device.

According to such a configuration, when there is a second transition, the application that was running at the time of the first transition can be started. (Hereinafter, the "application that was running at the time of the first transition" is referred to as the "last application".) Therefore, the user can supply power to the portable device from the vehicle without any particular operation. You can use the last app just by changing from the state without to the state with. In this configuration example, even if an application other than the last application is used without power supply from the vehicle after the first transition, if there is a second transition after that, the last application is started. Therefore, for example, the user enjoys the convenience that the same application that the user last used during the previous boarding can be automatically started by the second transition during the current boarding. Can be done. In general, the type of application used by the user differs depending on whether the portable device is used inside the vehicle or outside the vehicle, and it is considered that a specific application is often used inside the vehicle. It is convenient for the user that the same application that was used during the previous ride is automatically launched during this ride.

The presence or absence of power supply from the vehicle can be determined by various methods. For example, it is preferable to determine whether or not the portable device is in the vehicle by communicating with the vehicle, and if the portable device is supplied in the vehicle, it is determined that the power is supplied from the vehicle.

The information indicating the last application may be information for starting the execution of the last application, for example, the activation path of the last application.

If the last application storage means is configured with a non-volatile memory, the last when there is a second transition even if the power supply from the external power supply is cut off, the battery of the portable device is dead, or the power button is turned off. This is good because the application indicated by the information stored in the application storage means can be started.

Assuming that the memory of the last application to the last application storage means is immediately after the first transition, the memory of the last application can be more reliable. For example, even if the internal battery is almost empty, it is considered that the electric power required for the memory of the last application can be charged by the power supply from the vehicle before the first transition.

As a configuration that "can be operated by power supply from multiple external power sources including the vehicle and power supply from the internal battery", the internal battery is charged by the power supply from the external power supply, and when the power supply from the external power supply is cut off, it is internal. It is preferable to have a configuration in which the operation can be continued by continuing the power supply from the battery. The last application memory function should be performed when the power supply state is changed in this way, and should be configured to be performed when the power is supplied from the internal battery.

As a configuration in which "a plurality of applications can be executed", for example, a configuration in which a plurality of applications are switched and operated by time division or the like on an operating system capable of executing a plurality of applications by multitasking or the like is preferable. (For example, a dot matrix display) is configured to draw by executing an application program, and in particular, almost the entire area of the screen (for example, an area excluding the area used by the operating system) by one application program, etc. ) Is occupied and operates, and it is particularly effective. For example, on an operating system that operates by occupying almost the entire area of the screen with one application program in order to facilitate touch operations on the touch panel provided on the screen and to reduce power consumption during application execution. It is very effective in application programs that run on Android (for example, activities in Android®). For example, since one application program occupies almost the entire area of the screen, the last application can be uniquely determined, and the last application such as a configuration in which a plurality of application programs share the entire screen in a window or the like. You don't even have to decide which window the app should be. When the OS is Android (registered trademark), the application of "plurality of applications" may be an activity.

In the case where a plurality of application programs share the entire screen in a window or the like, one application or a plurality of applications determined by a predetermined rule may be the last application, but all the applications are the last applications. It is good to say.

<Structure example 2>
Power supply to the portable device from the vehicle and power supply to the portable device from an external power source other than the vehicle are performed via cables having different specifications.
The vehicle power supply determination function is a portable device characterized in that it determines whether or not power is supplied from a vehicle based on a difference in cable specifications.

By doing so, it is possible to automate the determination of the presence or absence of power supply from the vehicle. For example, as a cable for power supply from a vehicle, a cable in which a specific line is connected to GND is used, and as a cable for power supply from a power source other than the vehicle, a cable in which a specific line is opened is used. It is advisable to determine whether or not power is supplied from the vehicle depending on whether the specific line is GND or open.

<Structure example 3>
It also has a power supply judgment function that determines whether or not power is being supplied from an external power source other than the vehicle.
When there is a third transition, which is a transition from a state in which power is supplied from an external power source other than the vehicle to a state in which there is no power supply, information indicating the application that was being executed at the time of the third transition is used as a storage means. A portable device characterized by not remembering.

By doing so, it is possible to prevent an increase in processing load and use of storage capacity due to storage of unused information.
<Structure example 4>
A portable device characterized in that the last application activation function is not executed when the second transition occurs while the portable device is powered on.

When the portable device is powered on, the user may be using another application, and when the application is launched, which is indicated by the information stored in the last application storage means, the user is in use. The application may be terminated. In this configuration example, it is sufficient to prevent inconveniences such as the application being used by the user being forcibly terminated by starting the last application.

<Structure example 5>
A portable device further comprising a first transition sleep function that executes a transition of the portable device to a sleep state when the first transition occurs.

In this configuration example, it may be possible to prevent the internal battery from being consumed when the power-on state continues after the first transition. This configuration example is particularly useful in an embodiment in which power can be received from the vehicle only when the vehicle engine is on. Assuming that the portable device is used on a daily basis while being connected to the power supply cable of the vehicle, in this embodiment, the charge is likely to be low because the device is charged only while driving, so that this configuration is highly useful. .. It is especially useful when the user's daily driving time is short or in the summer when the internal battery is not charged at high temperatures.

<Structure example 6>
The first transition sleep function is
After the elapse of a predetermined waiting time from the first transition, the transition to the sleep state is executed,
A portable device characterized in that when a predetermined operation is performed on the portable device within the standby time, the transition to the sleep state is stopped.

In this configuration example, the transition to the sleep state can be stopped by a predetermined operation within a predetermined standby time, and the user can continue to use the portable device after the second transition as needed. It is good because it becomes. The predetermined waiting time may be, for example, 5 seconds. The predetermined operation may be, for example, an operation on the power button or an operation on the touch panel. For example, the first transition sleep function displays to notify the user that the sleep state will be entered after the waiting time elapses when the first transition occurs, and a predetermined operation is performed within the waiting time. In that case, the display should be erased.

<Structure example 7>
The first transition sleep function is a portable device characterized in that a background task is stopped when the transition to the sleep state is executed.

In this configuration example, the background task is stopped at the time of transition to the sleep state by the first transition sleep function, so that the possibility of preventing the consumption of the internal battery is improved. The first transition sleep function may stop all or part of the background task. If the OS is Android®, it is advisable to stop all or part of the service. For example, if the communication function such as WLAN or Bluetooth (registered trademark) is configured to be stopped, even if the user leaves the vehicle while the portable device is left in the vehicle, the portable device from outside the vehicle can be used. It is even better because it enhances security, such as preventing unauthorized use of data. If the audio output is configured to be stopped at the time of transition to the sleep state by the first transition sleep function, it is considered that the portable device seems to be turned off in conjunction with the second transition from the user's point of view. Therefore, it is possible to prevent an unnatural feeling that may be given to the user when the audio output is continued.

<Structure example 8>
A portable device further comprising a car mode transition function for shifting to a car mode in which the GPS function and / or communication function of the portable device is enabled when the second transition occurs.

Applications used in vehicles often use GPS and / or communication functions. For example, a car navigation application may require a GPS function and may need to be connected to the net via WLAN or the like. Further, in an application for hands-free calling, communication with a mobile phone using wireless communication such as Bluetooth (registered trademark) is required. In this configuration example, when there is a second transition, the car mode shifts to the car mode in which the GPS function and / or the communication function is enabled, so that such an application may be used smoothly. In the car mode, disabling the GPS function and / or the communication function by the user's operation may be prohibited. In this way, the smooth use of the application used in the vehicle can be ensured, and since the power supply is secured by the power supply from the vehicle, the GPS function and / or the communication function is disabled. This may give priority to the convenience of the user who does not have to set the GPS function and / or the communication function during driving, etc., rather than preventing the consumption of the internal battery.

<Structure example 9>
The multiple applications
The first launcher application for displaying the first launcher screen where icons can be placed, and
A second launcher application for displaying a second launcher screen on which an icon having a size larger than that of the first launcher screen can be arranged is included.
When the application indicated by the information stored in the last application storage means is the first launcher application, the last application activation function executes the second launcher application when there is the second transition. A portable device characterized by that.

In this configuration example, two types of launcher screens in which icons of different sizes are arranged can be used, which may improve user convenience. When the last application is the first launcher application, the second launcher screen on which a large icon is arranged is displayed by the second transition. The second launcher screen is easy to operate due to the large icon size. When the portable device is installed and used in a vehicle, the distance between the user and the portable device becomes long, the user extends the elbow to the portable device installed on the dashboard, etc., and the user operates the portable device. Because the portable device is installed in a position that does not interfere with the driving view of the user, there is shaking while driving, and the user cannot gaze at the screen while driving. It is difficult to perform detailed operations, and it is preferable that the user's convenience is improved by displaying the easy-to-operate second launcher screen instead of the first launcher screen.

The icon may be, for example, an image to which a function such as starting an application corresponding to the icon is assigned when the icon is operated. If the icon on the second launcher screen is configured to activate the entire icon and execute the function corresponding to the icon 121 regardless of which part of the icon is operated, the ease of operation is improved. So good.

<Structure example 10>
It also has a navigation bar display function that displays the navigation bar on which the icon is placed.
The second launcher screen has an icon arrangement area in which icons can be arranged and a blank area in which icons are not arranged.
A portable device characterized in that the blank area is arranged between the navigation bar and the icon arrangement area.

In this configuration example, since a blank area is arranged between the navigation bar and the icon arrangement area, inconveniences such as an accidental operation of the navigation by a user who intends to operate the icon in the icon arrangement area are less likely to occur. So good. In this configuration example, in the configuration in which the navigation bar is provided with an icon for transitioning to the first launcher screen, the user operates the icon by mistake, and the transition to the first launcher screen is difficult in the case of in-vehicle use. This is especially good because it is less likely to cause inconvenience. In this configuration example, in a portable device in which the navigation bar is always displayed by the OS, there is a high need for this configuration example in order to prevent erroneous operation of the navigation bar.

<Structure example 11>
A voice command registration function for registering any of a plurality of types of words and phrases for the icon placed on the second launcher screen, and
A portable device having a voice command execution function that executes a function assigned to a registered icon when any one of the words is recognized by voice.

In this configuration example, the user can operate the icon on the second launcher screen by speaking a voice command, so that the operability may be further improved. If the voice command registration function is configured to register any voice command selected from a plurality of voice commands, the target of voice recognition is limited to the plurality of voice commands, so that the process related to voice recognition is simplified. It is good because it is done. If the voice command registration function is configured so that the same voice command is not registered for a plurality of icons, the process executed by the voice command execution function may be simplified. The voice command execution function may be able to execute the icon function only when the second launcher screen is displayed.

<Structure example 12>
The icon arranged on the second launcher screen has a name display unit and has a name display unit.
The name of the function assigned to the icon is displayed in the name display section of the icon for which the phrase is not registered.
A portable device characterized in that the word / phrase registered in the icon is displayed on the name display unit of the icon in which the word / phrase is registered.

In this configuration example, the user may easily recognize the voice command that needs to be spoken in order to operate the icon.

<Structure example 13>
The second launcher application is a portable device characterized by displaying a predetermined voice mark on an icon in which the phrase is registered.

In this configuration example, the voice mark may allow the user to recognize that the voice command is registered in the icon. If the voice mark is, for example, a mark having a shape representing a person speaking, the user can understand that he / she is requested to speak. For example, in the configuration example 11 that cites the configuration example 10, the user can operate the icon by reading out the name display unit of the icon having the voice mark, which is easy for the user to understand.

<Structure example 14>
A unique name is set for each of the positions where the icon can be placed on the second launcher screen.
A portable device further comprising a second voice command execution function that executes a function assigned to an icon arranged at the position where the recognized name is set when the name is recognized by voice.

In this configuration example, the user can also operate the icon on the second launcher screen by speaking the name set for each icon placement position. Therefore, the user can operate the icon on the second launcher screen. It is good because the ease of use is further improved. Since the name for the icon operation is determined by the position of the icon, the user may easily remember the name required for the operation of each icon. For example, if the icons are arranged in a matrix and serial numbers such as 1, 2, 3 ... Are set as names from the upper left, it may be easy for the user to understand.

<Structure example 15>
It also has a voice command setting function for enabling / disabling the voice command execution function and / or the second voice command execution function.
The voice command setting function is a portable device characterized in that it is possible to individually enable / disable the state in which power is supplied from the vehicle and the state in which power is not supplied from the vehicle.

In this way, the user enables, for example, the voice command execution function and / or the second voice command execution function when there is power supply from the vehicle, and the voice command execution function when there is no power supply from the vehicle. And / or the second voice command execution function can be disabled. For example, when used inside the vehicle, it is possible to operate with a voice command, and when used outside the vehicle, it is possible to prevent the icon functions from being executed one by one when the voice command is spoken, which may improve user convenience.

If there is a forward application at the time of executing the home screen display function, the home screen display function puts the forward application into a hibernation state as a back stack and then displays the home screen 110.

FIG. 5A shows an example of the home screen 110. Icons 111 for executing various applications are arranged on the home screen 110. When each icon 111 is touched on the home screen 110, the control unit 31 starts the application corresponding to the icon 111. For example, when the icon 111a (“car navigation” icon) in FIG. 5 is touched, the screen 112 by the application corresponding to the icon 111a is displayed on the application display unit 101 as shown in FIG. 5 (b).

The user can arrange the icon 111 corresponding to any installed application (for example, an application that he / she frequently uses) stored in the application storage unit 33a on the home screen 110. The size of the icons on the home screen 110 is relatively small, and a larger number of icons 111 can be arranged. Therefore, it is convenient for the user to launch more types of applications from the home screen 110. The size and arrangement interval of the icons 111 are determined so that the operability is comfortable when the user holds the portable device 1 with one hand and operates it at a position relatively close to the eyes. Each icon 111 is activated only near the center, and the corresponding application is applied only when the center is touched, so that the trouble of starting an unintended application when the adjacent icon 111 is accidentally touched is reduced. Is supposed to start.

In the car launcher display function, the control unit 31 displays the car launcher screen 120 on the application display unit 101 by executing the second launcher application stored in the application storage unit 33a, and the setting button 103f is displayed on the navigation bar 103. Is a function to additionally display. The car launcher display function performs this display when the car launcher button 103e is touched and in accordance with the control of the state transition function described later. If there is a forward application at the time of executing the car launcher display function, the control unit 31 puts the forward application into a hibernation state as a back stack and then displays the car launcher screen 120.

FIG. 6 shows an example of the car launcher screen 120. The car launcher screen 120 occupies the entire area of the application display unit 101. The car launcher screen 120 has an icon arrangement area 120a located above the application display unit 101 and a blank area 120b located below the application display unit 101. In the icon arrangement area 120a, eight icons 121 having a relatively large size and roughly square are arranged at equal intervals in 2 rows and 4 columns.

Each icon 121 includes a number display unit 121a for displaying icon numbers 1 to 8, a pattern display unit 121b for displaying a pattern representing an application, a voice mark display unit 121c for displaying a voice mark, and a name display unit 121d. Have. The picture display unit 121b and the name display unit 121d are displayed only on the icon 121 in which the application is registered by the application registration function described later, and the voice mark display unit 121c is an icon in which the voice command is registered by the voice command registration function described later. It is displayed only on 121. However, when the voice command function described later is off, the car launcher display function hides the voice mark. The name of the application is displayed on the name display unit 121d. The display of the name display unit 121d will be described later. Only the number display unit 121a is displayed on the icon 121 in which the application is not registered.

When the icon 121 in which the application is registered is touch-operated on the car launcher screen 120, the control unit 31 starts the corresponding application. For example, in FIG. 6A, when the icon 121 (“car navigation” icon) of the icon number 1 is touched, as shown in FIG. 5B, the screen 112 by the application corresponding to the icon 111a is displayed on the application display unit. It is displayed on 101.

Each icon 121 is active as a whole, and when any part of the icon 121 is touched, the control unit 31 starts the application corresponding to the icon 121. The icon 121 is not arranged in the blank area 120b. Even if the blank area 120b or the icon 121 for which the application is not registered is touched, the control unit 31 does not perform any operation.

Since the number of icons 121 is small and the arrangement is fixed, the user can easily recognize the position of each icon 121 even during driving. Further, since the icon 121 is large and the application is started by touching any part, even if the position of the portable device 1 is relatively far from the user (the positional relationship is such that the user reaches out and operates). Even if the user is driving and cannot gaze at the screen, he / she can easily operate the screen. Since the blank area 120b is provided between the icon arrangement area 120a and the navigation bar 103, there is less concern that the user will mistakenly operate the navigation bar 103.

In this way, apart from the home screen display function that displays the home screen 110 that is excellent in operability when the portable device 1 is held and operated by hand, the portable device 1 is fixed to the vehicle and is used during driving or the like. Having a car launcher function that displays a car launcher screen 120 that is excellent in operability when operating facilitates operation both when it is carried and when it is fixed to a vehicle.

The application registration function is a function in which the control unit 31 assigns the application stored in the application storage unit 33a to the icon 121 based on the user's operation.

Specifically, when the setting button 103f is operated, the control unit 31 displays a button displaying the characters "setting" in the blank area 120b, and when the button is operated, the control unit 31 sends the application. The display unit 101 displays the application addition / editing screen 130 shown in FIG. 7A.

The application addition / editing screen 130 is provided with eight setting areas 131 corresponding to the eight icons 121. Each setting area 131 includes a number display unit 131a, a picture display unit 131b, a voice mark 131c, a name display unit 131d, and a button display unit 131e.

The control unit 31 displays the number display unit 131a, the pattern display unit 131b, the voice mark 131c, and the name display unit 131d only in the setting area 131 corresponding to the icon 121 registered by the application. The display contents of the number display unit 131a, the pattern display unit 131b, and the name display unit 131d are the same as those of the number display unit 121a, the design display unit 121b, and the name display unit 121d of the icon 121. The control unit 31 displays the pattern display unit 131b, the voice mark 131c, and the name display unit 131d only in the setting area 131 corresponding to the icon 121 registered by the application. An edit button is displayed on the button display section 131e of the setting area 131 corresponding to the icon 121 registered by the application, and a registration button is displayed on the button display section 131e of the setting area 131 corresponding to the unregistered icon 121. To do.

When the user touches the registration button of the setting area 131 corresponding to the icon 121 in which the application is not registered, the control unit 31 displays all the applications (excluding the registered ones) installed in the application display unit 101. If any of them is touched by the user, the application is registered for the icon 121. For example, when an application named "high-performance camera" is registered by operating the registration button of the setting area 131 having the icon number 4, the control unit 31 has the number 4 as shown in FIG. 7B. The number display unit 131a, the pattern display unit 131b, and the name display unit 131d of the setting area 131 display the corresponding information of the application, the voice mark 131c is displayed, and the edit button is displayed on the button display unit 131e.

When the user touches the edit button of the setting area 131 corresponding to the registered icon 121 of the application, the control unit 31 displays the delete icon on the application display unit 101 and all the installed applications (registered ones). (Excluding) is displayed, and when any application is touched by the user, the application registered for the icon 121 is changed. When the delete icon is touched, the control unit 31 cancels the registration of the application for the icon 121. For example, when the delete icon is touched after the edit button of the fourth setting area 131 is touched, the application addition / edit screen 130 is in the state of FIG. 7A.

When the application is registered or changed / canceled for the icon 121 by the application registration function, the car launcher display function subsequently displays the car launcher screen 120 reflecting the registration or change / cancellation.

The voice command registration function is a function in which the control unit 31 registers a voice command for the icon 121 already registered by the application according to the operation of the user. Specifically, when the voice mark 131c of the setting area 131 corresponding to any of the icons 121 already registered by the application is touched on the application addition / editing screen 130, the control unit 31 gives a voice command to the setting area 131. The selection field 140 is displayed.

FIG. 8 shows an example of the voice command selection field 140. The control unit 31 displays the character "None" and a plurality of voice commands (excluding registered ones) stored in the voice command storage unit 33c in the voice command selection field 140 in a list format, and any one of them. When the voice command is touched, the control unit 31 registers the voice command for the corresponding icon 121.

Further, the control unit 31 displays the registered voice command on the name display units 121d and 131d in which the voice command is registered. For example, when the voice command 131c of the setting area 131 of the icon number 4 in FIG. 7B is touched and then the voice command of “camera” is touched in the voice command selection field 140 of FIG. The characters "camera" are displayed on the corresponding name display units 121d and 131d on the car launcher screen 120 and the application addition / editing screen 130. In this way, the name display units 121d and 131d of the icon 121 in which the voice command is registered displays only the registered voice command (for example, "camera") and the name of the application (for example, "high-performance camera"). Is not displayed. This allows the user to easily recognize the voice command to be pronounced in order to activate the icon.

The character "None" in the voice command selection field 140 is displayed only when the voice mark 131c in the setting area 131 corresponding to the icon 121 in which the voice command is registered is touched. When "None" is touched, the voice command registration function cancels the registration of the voice command for the icon 121.

The GPS function is a function in which the control unit 31 detects the current position by the GPS receiving unit 34. The WiFi function and the Bluetooth function are functions in which the control unit 31 communicates with an external device via the communication unit 40.

The car navigation function is a function realized by the control unit 31 executing the application "car navigation". The road map 113 is displayed on the application display unit 101, and the current position detected by the GPS function is superimposed on the road map 113. This is a function that displays a mark 114 and a mark indicating a notification target (see FIG. 5B), and provides route guidance and alerts during driving by voice from the speaker 38.

The hands-free function is a function realized by the control unit 31 executing the application "hands-free", and is carried by communicating with a paired mobile phone or smartphone using the Bluetooth function. This is a function for making a telephone call or the like via the portable device 1. That is, the control unit 31 receives voice data during a call from a mobile phone or the like using the Bluetooth function, outputs it from the speaker 38, and transmits the voice data input from the microphone 37 to the mobile phone or the like using the Bluetooth function. ..

The TV viewing function is a function realized by the control unit 31 executing the application "TV", and is a display device for displaying images and sounds of TV broadcasting based on broadcast radio waves such as One Seg received by the TV tuner 35. Output from 32 and speaker 38.

The voice recognition function is a function in which the control unit 31 recognizes an utterance by the user by analyzing the sound data from the microphone 37.

In the voice command function, when the voice recognition function recognizes the voice command registered in the icon 121 while the car launcher screen 120 is displayed, the control unit 31 activates the application registered in the icon 121. It is a function to make it. In the second voice command function, while the car launcher screen 120 is displayed, the voice recognition function is such that the numbers in the number display unit 121a such as "Ichiban", "Niban", and "Sanban" are spoken by the user. When it recognizes that, the control unit is a function to start the application registered in the icon 121 of the corresponding icon number. By the voice command function and the second voice command function, the control unit 31 activates the application registered in the icon 121 even when the utterance of either the voice command or the number registered in the icon 121 is recognized. For example, when the voice recognition function recognizes that the user has spoken "car navigation" or "most" while the car launcher screen 120 of FIG. 6 is displayed, the control unit 31 controls the icon 121 of the icon number 1. Start the application corresponding to.

The user setting function is a function in which the control unit 31 sets the operating conditions of the portable device 1 according to the operation of the user. The items that can be set by the user setting function are GPS function on / off, WiFi function on / off, Bluetooth function on / off, voice command function on / off, hands-free function on / off, no operation. In the case of, there are waiting time until the transition to the sleep state (hereinafter, "sleep waiting time"), audio volume, and power saving operation. The voice command function on / off, hands-free function on / off, sleep standby time, and audio volume can be set individually for each of the two operation modes (tablet mode and car mode). The GPS function on / off, the WiFi function on / off, and the Bluetooth function on / off can be set only for the tablet mode. The operating conditions made by the user setting function are stored in the config storage unit 33d.

The power supply determination function is a function in which the control unit 31 determines the power supply state for the terminal 12 from the external power source. Specifically, when the control unit 31 has a power supply to the terminal 12 (the voltage of the VBus pin is 5V), if the ID pin of the terminal 12 is short-circuited to the GND, the power is supplied from the vehicle. If it is open, it is determined that power is being supplied from the AC adapter. If it is open, the control unit 31 further determines whether the + D pin and the −D pin are short-circuited. If it is short-circuited, the quick charging AC adapter is used. If it is not short-circuited, the normal AC is used. It is judged that the power is supplied by the adapter. Further, the power supply determination function is based on the above-mentioned determination of the power supply state, the first transition which is the transition from the state where the power is supplied from the vehicle to the state where there is no power supply from the vehicle, and the state where there is no power supply from the vehicle. The second transition, which is the transition of, is determined. The control unit 31 has the power supply determination function at regular time intervals (for example, 1 second) regardless of the operating state of the portable device 1 (power on / off, sleep, what application is running, etc.). To execute.

In the last application storage function, when the first transition is determined by the power supply determination function, the control unit 31 determines the forward application (among the applications using the application display unit 101, the first application) at the time when the first transition is determined. It is a function that performs the following processing depending on whether or not there is an application other than the 1st and 2nd launcher applications). That is, when there is a forward application, the control unit 31 stores the activation path of the forward application in the last application storage unit 33b. (Hereinafter, the application whose startup path is stored in the last application storage unit 33b may be referred to as "last application".) When there is no forward application (only the first or second launcher application is running in the foreground. In the case), the control unit 31 erases the application startup path stored in the last application storage unit 33b.

The last application memory function executes the above process immediately after determining the first transition. As a result, the activation path can be stored and erased more reliably. This is because, at the time when the first transition is determined, it is considered that the battery 41 is charged with enough electric power to store the activation path by the power supply from the vehicle immediately before the first transition.

The first transition sleep function refers to a function in which the control unit 31 executes the following processing when the first transition is determined by the power supply determination function. Specifically, when there is a first transition, the control unit 31 superimposes on the screen 150 displayed on the application display unit 101 at that time, and cancels with the message 151 of "Soon to automatically sleep." The button 152 is displayed for a certain period of time (for example, 5 seconds) (see FIG. 9). If the cancel button 152 is not operated or the power supply to the terminal 12 is not restarted during that time, the control unit 31 puts the portable device 1 into the sleep state. When the cancel button 152 is touched within a certain period of time, or when the power supply to the terminal 12 is restarted, the control unit 31 does not shift to the sleep state and deletes the message 151 and the cancel button 152.

The last application activation function is a function in which the control unit 31 executes the last application activation process S100 when the second transition is determined by the power supply determination function in the sleep state or the power off state. FIG. 10 shows the last application activation process S100.

As shown in the figure, the control unit 31 reads the activation path of the last application storage unit 33b of the NVRAM in step S101, determines the presence or absence of the activation path in step S102, and stores the activation path in the last application storage unit 33b. If so, the last application is started according to the start path in step S103, and if the start path is not stored, the second launcher application is started in step S104.

By performing such processing, if there is a forward application running at the time of the previous first transition, the forward application is started in the second transition this time. Therefore, even if the user does not perform any particular operation, the same application as in the previous drive can be used simply by connecting the terminal 12 to the cigar socket with a dedicated cable, which is convenient. Also, if there is no forward application running at the time of the previous first transition, the car launcher screen 120 that can be easily operated even while driving is displayed by simply connecting the terminal 12 to the cigar socket with a dedicated cable. So it's convenient.

Even if the second transition occurs while the power of the portable device 1 is on, the last application activation function does not activate the application in the activation path stored in the last application storage unit 33b. Therefore, by connecting the terminal 12 from the dedicated cable to the cigar socket, it is possible to prevent inconveniences such as forced termination of the application being used by the user.

The tablet mode transition function is a function in which the control unit 31 sets the operating conditions of the portable device 1 to the tablet mode by executing the tablet mode setting process S200 in the state transition process described later. FIG. 11 shows the tablet mode setting process S200. As shown in the figure, the control unit 31 turns on / off the GPS function according to the setting for the tablet mode stored in the config storage unit 33d after executing the screen unlock (step S201, step S202) of the display device 32. Settings (step S203, step S204), WiFi function on / off setting (step S205, step S206), Bluetooth function on / off setting (step S207, step S208), sleep standby time setting (step S209, step S210) ), Audio volume setting (step S211 and step S212), voice command function on / off setting (step S213, step S214), and hands-free function on / off setting (step S215, step S216) are sequentially executed.

The car mode transition function is a function in which the control unit 31 sets the operating conditions of the portable device 1 to the car mode by executing the car mode setting process S300 in the state transition process described later. FIG. 12 shows the car mode setting process S300. As shown in the figure, the control unit 31 executes the screen unlock (step S301, step S302) of the display device 32, and then performs the GPS function (step S303, step S304), the WiFi function (step S305, step S306), and Bluetooth. The functions (step S307, step S308) are forcibly turned on, and further, the sleep is not set (step S309, step S310), and then according to the setting for the car mode stored in the config storage unit 33d. The audio volume setting (step S311, step S312), the voice command function on / off setting (step S313, step S314), and the hands-free function on / off setting (step S315, step S316) are sequentially executed.

As described above, in the car mode, the GPS function, the WiFi function, and the Bluetooth function are forcibly turned on, and these cannot be turned off by the user's operation. This is because these functions are necessary for the operation of many applications that are expected to be used in the vehicle, such as "car navigation", other driving support applications, and "hands-free". It prevents the inconvenience of the user when these functions are turned off in the car mode that is supposed to be used inside, and the above application does not operate normally when the user accidentally turns off these functions. This is to prevent the user from being confused or dissatisfied with the portable device 1. Since the power supply is secured by the power supply from the vehicle, it is not necessary to consider the consumption of the battery by turning on these functions. In addition, the reason why the sleep is not set is that it is considered inappropriate to shift to the sleep while using the "car navigation system" or the like.

The state transition function is a function in which the control unit 31 performs the state transition processing shown in FIGS. 13 to 18 to perform the transition between the power on / off state and the sleep state of the portable device 1.

FIG. 13 shows a portion of the state transition process related to the transition from the power-off state of the portable device 1 to the power-on state.

As shown in the figure, when the power button 6 is operated for 2 seconds or more (hereinafter, “long press”) from the power off standby state (step S401), the control unit 31 performs the power supply determination function in steps S402 to S404. Judge the power supply status by. Specifically, in step S402, it is determined whether or not power is supplied to the terminal 12, and if there is power supply, it is determined in step S403 whether or not the power is supplied from the vehicle. The type is determined, and in steps S405 and S406, charging is started at a speed corresponding to the type of the AC adapter. In the case of a normal AC adapter, the level of the battery 41 is determined in step S407. If there is no power supply in step S402, the level of the battery 41 is determined in step S408. If the AC adapter for quick charging is used in step S404, or if the battery level is high in steps S407 and S408, the portable device 1 is turned on and the OS is started in step S409. The tablet mode setting process S200 is executed, and thereafter, the portable device 1 is operated in the tablet mode. If there is no power supply in step S402, the level of the battery 41 is determined, and if the battery is low, the standby state is returned.

Further, when the power supply to the terminal 12 is detected in the standby state of the power off (step S411), it is determined in step S412 whether the power supply is from the vehicle, and if it is negative (N), the AC adapter is in step S413. In step S415 and step S416, charging is started at a speed corresponding to the type of the AC adapter, and then in step S418, the charging state is displayed and the standby state of power off is continued. Even when the battery level is low in step S407, the charging status is displayed in step S418, and the standby state for turning off the power is continued.

If the determination in step S403 or step S412 is affirmative (Y), charging is started in step S414, then the power of the portable device 1 is turned on and the OS is started in step S417, and then the car mode is set. After executing the process S300, the last application activation process S100 is executed, and thereafter, the portable device 1 is operated in the car mode.

FIG. 14 shows a portion of the state transition process related to the transition from the sleep state to the tablet mode or the car mode.

When the power button 6 is operated while the portable device 1 is in the sleep state (step S501), the control unit 31 determines in step S502 whether or not power is supplied to the terminal 12. Then, when the determination in step S502 is affirmative (Y) and when the power supply to the terminal 12 is detected in the sleep state (step S503), the control unit 31 determines whether the power supply is from the vehicle in step S504. If the judgment is negative (N), the type of the AC adapter is determined in step S505.

Then, when it is determined in step S502 that there is no power supply, or when it is determined in step S504 that the power supply is not from the vehicle, the control unit 31 releases the sleep in steps S509 to S511 and then the tablet. The mode setting process S200 is executed to start the operation in the tablet mode. If it is determined in step S502 that there is no power supply, charging is started at a speed corresponding to the type of the AC adapter in steps S506 and S507.

If the determination in step S504 is affirmative (Y), the control unit 31 starts charging in step S508, then wakes up from sleep in step S512, then executes the car mode setting process S300, and then starts the last application. The process S100 is executed, and thereafter, the portable device 1 is operated in the car mode.

FIG. 15 shows the transition to the tablet mode or the car mode when the power supply to the terminal 12 is detected when the portable device 1 is powered on without the power supply to the terminal 12 in the state transition process. The relevant part is shown.

When the control unit 31 detects the start of power supply to the terminal 12 in step S601, it determines whether the power is supplied from the vehicle in step S602, and if it is negative (N), determines the type of the AC adapter in step S603. Then, in steps S604 and S605, charging is started at a speed corresponding to the type of the AC adapter, the tablet mode setting process S200 is executed, and thereafter, the portable device 1 is operated in the tablet mode. If the determination in step S602 is affirmative (Y), the control unit 31 starts charging in step S606, then executes the car mode setting process S300, and thereafter operates the portable device 1 in the car mode.

As described above, even if the first transition (step S602: Y) occurs when the power of the portable device 1 is turned on, the last application activation process S100 is not executed. When the power is turned on, the user may be using another application, but by not executing the last application start processing S100, such an application in use is contrary to the user's intention. It is possible to prevent inconveniences such as termination.

FIG. 16 shows a part of the state transition process related to the transition from the car mode to the sleep state.

If the power button 6 is operated for less than 2 seconds (hereinafter, "short-time operation") while the portable device 1 is operating in the car mode (step S701), whether or not the terminal 12 is supplied with power in step S702. To judge. If this is affirmative (Y), it is determined in step S703 whether the power is supplied from the vehicle, and if this is negative (N), the type of AC adapter is determined in step S704, and charging according to the type is determined. Is started (step S706, step S707). If the determination in step S702 is negative (N), charging is not performed (step S705).

When the portable device 1 is operating in the car mode and transitions from a state in which power is supplied to the terminal 12 to a state in which there is no power supply to the terminal 12 (step S711), the control unit 31 ends charging in step S712 and waits in step S713. Is set to 5 seconds, the message 151 and the cancel button 152 are displayed on the application display unit 101 in step S714, it is determined in step S715 whether or not there is power supply to the terminal 12, and if this is negative (N), the step It is determined in S716 whether the cancel button 152 is touched, and if this is negative (N), the waiting time is counted down in step S717, and it is determined in step S720 whether the waiting time has timed out, and this is negative (N). ), The process proceeds to step S715.

If the determination in step S715 is affirmative (Y), the operation in the car mode (FIG. 16) is continued after the message 151 and the cancel button 152 are deleted in step S719. If the determination in step S716 is affirmative (Y), the message 151 and the cancel button 152 are erased in step S718, and then the car mode operation is continued with the power of the battery 41.

If the determination in step S720 is affirmative (Y), it is determined in step S721 whether or not there is a forward application, and if so, in step S722, the activation path of the forward application is stored in the last application storage unit 33b. If there is no (N), the activation path of the last application storage unit 33b is deleted in step S723.

After step S705, step S706, step S707, step S722, and step S723, the power saving setting is read from the config storage unit 33d in step S731, and it is determined in step S732 whether or not the power saving mode is on. If the judgment is affirmative (Y), the GPS function, WiFi function, and Bluetooth function are turned off in steps S732 to S735, the audio output is muted in step S736, and the portable device 1 is turned off in step S737. Put it to sleep. If the determination in step S732 is negative (N), step S733 to step S736 are skipped and step S737 is executed. The audio output was muted in step S736 because the transition to the sleep state (step S737) seems to the user that the portable device 1 has been turned off. If it is continued, it may give a feeling of anxiety or unnaturalness to the user, so this is prevented.

FIG. 17 shows a process in which the power button 6 is operated for a short time or the power supply at the terminal 12 is cut off during the operation in the tablet mode among the state transition processes.

When the power button 6 is operated for a short time while the portable device 1 is operating in the tablet mode (step S801), the control unit 31 determines in step S802 whether or not power is supplied to the terminal 12, and denies (N). In the case of, charging is terminated in step S805. If the determination in step S802 is affirmative (Y), in steps S803 and S804, it is determined whether the power is supplied from the vehicle and the type of the AC adapter, and charging is started at a speed corresponding to the type of the external power source. (Step S806, Step S807). After steps S805 to S807, the control unit 31 puts the portable device 1 into a sleep state.

When the power supply to the terminal 12 is cut off while the portable device 1 is operating in the tablet mode (step S808), charging is terminated in step S809, and the tablet mode operation is continued with the power of the battery 41.

FIG. 18 shows a process in which the power button 6 is pressed and held during operation in the car mode or the tablet mode among the state transition processes.

When the power button 6 is long-pressed (step S901), or when the "turn off" selection operation is performed on the menu screen displayed by the control unit 31 when the power button 6 is long-pressed. The control unit 31 determines in step S902 whether or not there is power supply to the terminal 12, and if negative (N), ends charging in step S905. If the determination in step S902 is affirmative (Y), the type of the external power source is determined in steps S903 and S904, and charging is started at a speed corresponding to the type of the external power source in steps S906 and S907. After steps S905 to S907, the portable device 1 is shut down (powered off) in step S908, and then waits.

The status notification function is a function in which the control unit 31 displays a display for notifying the operating status of the portable device 1. Specifically, when the portable device 1 is operating in the car mode, and when the voice command function is on, a notification notifying that the portable device 1 is operating in the car mode and the voice command function is on. The icons are displayed in the left area 102b of the status bar 102, and they are displayed on the notification panel 102e.

Although the preferred embodiment has been described above, examples of the shape, dimensions, material, function, operation mode, control mode, control parameter, operation mode, etc. of the device, system, program or its element, member, etc. in the above embodiment. These are described as, and these can be changed.

For example, in the above embodiment, the case where the start path of the last application storage unit 33b is stored is shown, but other information indicating the application that was being executed when the first transition occurred is stored instead of the start path. Remember, the last app launch function may launch the application indicated by the information.

In the above embodiment, an example is shown in which the activation path of the last application storage unit 33b is deleted when there is no forward application when there is a first transition. For example, when there is a first transition, a second is performed. If the launcher application is running, the launch path of the second launcher application may be stored. In addition, if the first launcher application is running when the first transition occurs, information indicating that is stored, and if the information is stored, the last application activation function is stored. May launch the second launcher app when there is a second transition.

In the above embodiment, the last application storage function is an application stored in the last application storage unit 33b only when only the first or second launcher application is being executed in the foreground when the first transition is determined. The case of erasing the start path of is described. For example, when the first transition is determined, the last application storage unit is also running when the program for setting the operation of the portable device 1 is being executed in the foreground. The application startup path stored in 33b may be deleted.

In the above embodiment, when the power of the portable device 1 is turned on, even if the second transition (step S602: Y) occurs, the last application activation process S100 is not executed. However, the portable device 1 is the power source. The last application startup process S100 may be executed even when the second transition (step S602: Y) occurs in the ON state. By doing so, the program can be simplified and a bug Can be reduced. Further, since the last application activation process S100 is executed for a series of operations of mounting the vehicle on an automobile and turning on the engine, there is no great sense of discomfort for the user.
