Hereinafter, a control method of controlling the volume of the sound output from the sound output unit 152 based on the voice control command input from the user or the external environment information of the mobile terminal 100 will be described in detail.

3 is a flowchart illustrating a control method according to the present invention. 4A is a conceptual diagram for explaining a control method of FIG. 3 using a discharge pattern according to an embodiment. 3 and 4A, a warning alarm output method using a discharge pattern according to time will be described.

The memory 160 records the first discharge pattern information 310 according to the time of the power supply unit (battery, power supply unit) (S301). Here, the first discharge pattern information 310 records the power capacity over time from the time S when the user charges the power supply unit to the time E when the power supply unit is completely discharged.

For example, as shown in FIG. 4A, the first discharge pattern information 310 may be recorded by measuring the capacity of a power source from 12:00 am to 9:00 pm. When the capacity of the 100% capacity of the power source reaches 9 o'clock at 12 am, the battery is completely discharged to 0% of the capacity and the power is discharged from 12 o'clock to 9 o'clock. The average discharge speed can be calculated and recorded at intervals of 3 hours.

As shown in FIG. 4A, the discharging speed may be differently measured according to the divided periods according to time. That is, the discharge rate is very fast by 12 o'clock, and the discharge rate can be measured slowly from 12 o'clock to 3 o'clock. The discharge speed may be based on a type of a program driven by the mobile terminal, a number of programs, an input of a user's control command, and the like.

Also, the first discharge pattern information 310 may be calculated as an average amount of use of the mobile terminal for a predetermined period of time. Accordingly, when the user uses the mobile terminal in a similar situation as usual, it can be expected that the power of the power supply unit is discharged similarly to the first discharge pattern information 310. [

In the figure, the first discharge pattern information 310 from the power source 100% to the state where the power source is completely discharged to 0% is shown, but the present invention is not limited thereto. Depending on the user setting, you can specify the amount of power charged, the time at which the discharge starts, and the time at which the battery can be recharged.

In addition, various kinds of first discharge pattern information 310 can be formed according to user's setting. For example, the first discharge pattern information 310 when the specific event is included in the schedule of one day, the first discharge pattern information 310 when the time between the charge time and the discharge time is long, And the discharge patch information in the case where this is continued for a long time can be formed.

During the driving of the mobile terminal, the remaining power of the power supply unit is measured (S302), and information about the remaining power is output (S303). 4A, the controller 180 may control the display unit 180 to output an image representing a remaining percentage and an amount of remaining power to display the remaining power of the power source . The control unit 180 controls the display unit 180 to display the remaining amount of time-varying method in the same manner.

The difference between the remaining amount of the first discharge pattern information 310 and the measured remaining amount is calculated at a specific reference point (S304). Referring to FIG. 4 (d), the controller 180 measures the remaining amount of the power source according to the time, and measures the remaining amount of the first discharge pattern information 310 at a specific time, The difference of the remaining amount is calculated. .

For example, the remaining amount of the power measured at 3:15 PM is 20 (%), and the remaining amount corresponding to 3:15 PM of the first discharge pattern information 310 is about 50 (%). Accordingly, the difference in the remaining amount is calculated as 30 (%) at a specific time (3:15 pm), which is a specific reference point.

It can be seen that the actually measured discharge speed is faster than the discharge speed based on the first discharge pattern information 310 between 12:00 and 3:00.

The difference is compared with a predetermined allowable range to output a warning alarm (S305).

Referring to FIG. 4A, the controller 180 compares the difference between the remaining amount measured based on substantially the same time and the remaining amount of the first discharge pattern information 310 with the allowable range to output a warning alarm (S305 ). For example, the control unit 180 may control the output unit 150 to output a warning alarm when the difference is greater than or equal to the allowable range.

The permissible range may be specified by the setting of the user. That is, the user can adjust the time to receive the warning alarm by adjusting the allowable range.

As shown in the figure, when the allowable range is designated as 30 (%), when the difference between the measured remaining amount and the recorded remaining amount is calculated as 30 (%), (150).

For example, as shown in (c) of FIG. 4A, the controller 180 may control the mobile terminal such that the brightness of the path alarm becomes dark. That is, the control unit 180 controls the driving state of the mobile terminal so that the discharge speed of the power supply unit is reduced.

It is automatically notified to the user when it is expected to be discharged in a shorter time as compared with the discharge pattern information. Accordingly, it is possible to consider the method of stopping unnecessary power use or recharging the power supply.

Accordingly, it is possible to prevent a discharge state in a situation in which the power supply unit is discharged in an unexpected situation and the use of the mobile terminal is indispensable.

The discharge pattern information may be recorded in various forms other than the recorded type according to the passage of time. Hereinafter, discharge pattern information according to various embodiments will be examined.

FIG. 4B is a conceptual diagram for explaining a control method by the second discharge pattern information 320 including information on the remaining power of the power source according to the movement path. The components of the control method except for the form of the second discharge pattern information 320 are substantially the same as those of FIG. 4A, and the description of the same components is omitted from the description of FIG. 4A.

Referring to FIG. 4A, the second discharge pattern information 320 is composed of a travel path and a remaining amount of a power source, which are indicated on a map including location information. That is, the discharge pattern information includes a movement path during which the discharge is progressively discharged while the power source is charged to 100%. In addition, the second discharge pattern information 320 may include a remaining amount of power corresponding to a preset point of each movement path.

The control unit 180 may drive a GPS or the like to determine the current position of the mobile terminal. The controller 180 may match the current position of the mobile terminal detected by the GPS or the like with the remaining amount of the measured power. Also, the controller 180 may match the remaining amount corresponding to the predetermined point included in the second discharge pattern information 320.

The control unit 180 may compare the remaining amount measured at the reference position with the remaining amount recorded in the second discharge pattern information 320 to calculate the difference. That is, the difference between the remaining amount of 20 (%) measured in the area A and the remaining amount of 50 (%) recorded in the second discharge pattern information 320 is calculated.

If the difference between the measured remaining amount and the recorded remaining amount is equal to or greater than a predetermined allowable range, the controller 180 controls the display unit 180 to adjust the brightness of the screen information to be dark.

According to this embodiment, when the movement path of the mobile terminal according to the time is substantially the same, the discharge pattern according to the movement path can be predicted.

4C is a conceptual diagram for explaining a control method by the third discharge pattern information 330 including the discharge speed recorded for each day of the week. The components of the control method except for the form of the third discharge pattern information 330 are substantially the same as those of FIG. 4A, and the description of the same components is omitted from the description of FIG. 4A.

Referring to FIG. 4C, the third discharge pattern information 330 includes a discharge rate corresponding to each day of the week. The discharge rate may be expressed as a ratio (% / h) of the power source discharged in one hour. That is, the third discharge pattern information 330 includes the average discharge rate during one day for each day regardless of the charging and discharging states of the power supply unit.

The control unit 180 measures the remaining amount of the current power supply unit. Also, the controller 180 calculates the difference between the remaining amount and the remaining amount of the third discharge pattern information 330 at the current time. Specifically, assuming that the power supply unit starts discharging at a fully charged state (100%) at 9:00 on Wednesday, the remaining amount recorded by the third discharge pattern information 330 may be calculated to be about 70% .

Therefore, the difference between the recorded remaining amount (70%) and the measured remaining amount (40%) is calculated as 30% and compared with the predetermined allowable range (30%). The control unit 180 controls the display unit 180 to adjust the brightness of the screen information to be dark.

According to the present embodiment, it is possible to more accurately grasp the discharge pattern of the user whose schedule is different for each day of the week.

5A to 5C are conceptual diagrams for explaining a warning alarm method according to various embodiments.

A warning alarm method when a specific application is running will be described with reference to FIG. 5A. 5A is a diagram illustrating a case where a moving picture is played back on the display unit 180 as an example of a specific application.

Referring to FIGS. 5A and 5B, the controller 180 may control the mobile terminal to terminate the application being executed. That is, the control unit 180 may restrict the execution of the application and may control the display unit 180 to switch from the execution screen of the application to other screen information. The screen information may correspond to a home screen page, a preset image, and the like, and the amount of power required to output the screen information may be substantially less than a power required to drive the execution screen.

The type of application whose execution is restricted can be specified by the user's setting or can be specified in accordance with the consumption amount of power according to the execution of the application.

According to the present embodiment, it is possible to warn the user that the discharge speed is high due to the restriction of the execution of the application which consumes a large amount of power, and the discharge speed can be effectively reduced.

Referring to FIGS. 5A and 5C, the controller 180 controls the display unit 180 to reduce the size of the execution screen. The size of the execution screen may be formed to be smaller than the display area defined by the display unit 180 and the remaining area of the display area on which the execution screen is output may be inactivated .

Accordingly, it is possible not only to warn the user that the discharge speed is high, but also to reduce the power consumed in outputting the execution screen to the entire display area, so that the discharge speed can be effectively reduced.

Referring to FIGS. 5A and 5D, the controller 180 controls the display unit 180 to output an alert window 400. FIG. For example, the warning window 400 may include a warning message such as a 'rapid discharge warning' and a warning message such as 'estimated two hours', based on the first to third discharge pattern information 310, 320, And may include information on the drivable time.

Accordingly, the user can recognize the available time of the mobile terminal.

Referring to FIG. 5B, a control method in which a warning alarm is implemented by a speaker will be described. The controller 180 may control the speaker to switch to the mute mode.

For example, as shown in the figure, when the moving picture file is played back, the controller 180 may limit the speaker to limit the sound output of the moving picture file as the warning alarm.

Referring to FIG. 5C, the controller 180 controls the haptic module 154 to generate vibration in response to a warning alarm. The controller 180 may control the haptic module 154 to generate the vibration at predetermined intervals. Therefore, even when the user does not recognize the display unit 180, it is possible to recognize the state of rapid discharge.

Meanwhile, the controller 180 controls the mobile terminal to implement at least one of the alert alarms according to the various embodiments.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
