Description

  The present invention relates to a portable terminal device such as a mobile phone, a mobile PC, and a PDA, and in particular, an operation of the portable terminal device by a user driving the vehicle or the like by performing automatic mode switching during driving of the vehicle or the like. The present invention relates to a portable terminal device to be restricted and a mode switching method in the portable terminal device.

In portable terminal devices such as mobile phones (including PHS), mobile PCs, PDAs, etc., avoiding danger and inconvenience to the surroundings while driving a vehicle such as an automobile or traveling on public transportation such as a bus or train. It is required to think and refrain from using it.
In particular, because of the frequent accidents caused by operating the mobile terminal device while driving a vehicle, on November 1, 2004, the penalties were strengthened for the act of making a call with the mobile terminal device or watching the screen. The revised Road Traffic Law has come into effect.

Therefore, hands-free kits that can respond without having to manually operate the mobile terminal device when there is an incoming call are also commercially available, but even when using a hands-free kit, It cannot be avoided that concentration on driving is reduced due to conversation.
In view of this, the technique described in Patent Document 1 discloses a technique in which incoming calls are restricted when the vehicle situation is detected and the driver has no room.
JP 2001-144850 A

  Moreover, in the portable terminal device described in Patent Document 2, while detecting the moving speed of the portable terminal device, the user of the portable terminal device determines the attribute of whether the user is a driver or a passenger of the mobile object, and the user When it is determined that the driver is moving at a speed exceeding a preset threshold, it is impossible to execute various operations such as an incoming call response operation, a transmission operation, a mail browsing operation or a message reproduction operation. In the case of a passenger, a technique is disclosed in which these can be used as usual.

In this technique, the attribute is determined by an external input device that does not operate unless the user operates with both hands. For example, the attribute of whether the user of the mobile phone is a driver or a passenger is determined depending on whether or not two possession detection switches provided on the main body (or casing) are simultaneously pressed.
JP 2004-015728 A (refer to description of claims and description of paragraph [0018])

However, the technique described in Patent Document 1 requires a connection between a mobile phone, a hands-free device, and an in-vehicle device, and there is a problem that the danger cannot be prevented if the device is not intentionally connected because of the troublesome connection. .
In addition, in the technique described in Patent Document 2, one of the advantages is that the mobile terminal device can be operated with one hand. However, although temporarily, this technique requires an operation with both hands to determine the attribute. There is a drawback of doing. In addition, in the temporary stop such as waiting for a signal, there is also a problem that the driver can perform the operation and can release it immediately.

  The present invention has been made in view of the above problems, and does not require connection of a hands-free device or an in-vehicle device, and does not require determination of the attributes of the driver or passenger, and automatically sets the drive mode during driving. The mobile terminal device that can be operated by one hand and can be operated with one hand when a call or the like is canceled after the drive mode is canceled unless the operation is interrupted. An object of the present invention is to provide a mode switching method in an apparatus.

  In order to solve the above-described problems, the invention described in claim 1 is a communication processing circuit that wirelessly transmits and receives data, a movement detection unit that detects movement of a moving body such as a vehicle, and movement of the movement detection unit. In a portable terminal device provided with a control unit that restricts the execution of various operations such as an incoming call response operation, a transmission operation, a mail browsing operation or a message reproduction operation based on detection, when the execution of the various operations is restricted, Password forming means for forming a predetermined password under a certain condition, and password output means for outputting the password formed by the password forming means by voice or image and prompting the user to input the same password as the password And a comparison unit that compares the input password and the output password. It is constituted to cancel the limitation of the execution of the various operations in the case of.

According to this configuration, the movement detection unit detects whether or not the mobile terminal device is moving with the vehicle or the like. If the control unit determines that the user of the mobile terminal device is moving at a constant speed (for example, 20 km / h) based on the detection result, an incoming call response operation, a transmission operation, a mail browsing operation, a message reproduction operation, etc. Restrict the execution of various operations.
This restriction can be released by the user entering a password. The password is formed by the password forming means under certain conditions, for example, when there is an incoming call or when the user operates the mobile terminal device. The formed password is displayed on a display or outputted by sound from a speaker. The user cannot respond to an incoming call unless a password that matches the displayed password is entered. Therefore, a user who is a driver cannot perform these operations while driving. When the user is a passenger, the portable terminal device can be used at any time by inputting a password even when the user is moving in a vehicle or the like.

If the same password is output repeatedly, the password is stored by the user, and the restriction can be released while driving. Therefore, as described in claim 2, the password forming means may form a different password each time.
Further, as the password, it is preferable to select a password that must be watched on a display screen of the mobile terminal device when the user inputs it, that is, a password that makes it impossible to drive a vehicle or the like.
For example, as described in claim 3, the password forming means may be configured to form a password from a plurality of characters, figures, symbols, or combinations thereof.

  As the movement detection means, various means can be used as long as it can detect that the user is moving on a moving body such as a vehicle. For example, as described in claim 4, the movement detection unit includes a position measurement system capable of measuring the position of the mobile terminal device, and a moving speed obtained by the position measurement system is set to a preset threshold value. When exceeded, the control unit may restrict execution of the various operations. Positioning systems include a global positioning system (GPS) that determines the global position by receiving radio waves from at least three satellites, and a current position by receiving radio waves from multiple base stations on the ground. A position measuring system can be used.

  When execution is restricted at the moving speed, the restriction may be continued even during a temporary stop during driving such as waiting for a signal or waiting for a crossing. In this case, as described in claim 5, when the moving speed shifts from a value greater than the threshold value to a value less than the threshold value, the moving speed becomes less than the threshold value. It may be configured such that execution restriction of various operations such as incoming call response is continued until a predetermined time has elapsed.

In addition, by using a short-distance two-way wireless communication technology such as Bluetooth (registered trademark) or UWB (Ultra Wide Band) that has begun to spread in recent years, it becomes possible to obtain information on a moving speed directly from a vehicle or the like. .
For example, as described in claim 6, the movement detection unit may detect the movement of the moving body by communicating with a control unit of the moving body.

The object of the present invention can also be achieved by the invention according to any one of claims 7 to 9.
The invention according to claim 7 is provided with a movement detection means for detecting the movement speed of a moving body such as a vehicle, and the movement speed detected by the movement detection means is larger or smaller than a preset threshold value. Determining whether or not when the moving speed is greater than the preset threshold, restricting the execution of various operations such as an incoming call response operation, a transmission operation, a mail browsing operation or a message playback operation; When execution of the various operations is restricted, a step of forming a predetermined password under a certain condition, and outputting the password formed by the password forming means by voice or an image, Both the step that prompts the user to enter the same password, the step that compares the input password with the output password, and the password comparison result There as a method having a step of releasing the restriction of the execution of the various operations if they match.

The invention according to claim 8 is a method of further preparing a position measurement system for measuring the position of the mobile terminal device, and obtaining a moving speed from the amount of change in position per unit time obtained by the position measurement system. is there.
Further, in the ninth aspect of the present invention, when the moving speed shifts from a value greater than the threshold value to a value equal to or less than the threshold value, a predetermined time has elapsed since the moving speed became equal to or less than the threshold value. This is a method of continuing the execution restriction of the various operations until elapses.

Since the present invention is configured as described above, it is not necessary to connect to a hands-free device or a vehicle-mounted device, and the mode can be automatically switched without determining the attributes of the driver and passengers. Is possible.
In addition, the drive mode can be set automatically during operation, and the drive mode cannot be canceled unless the operation is interrupted. can do.

Preferred embodiments of the present invention will be described in detail with reference to the drawings.
[First embodiment]
FIG. 1 is a block diagram illustrating a configuration of a mobile terminal device according to a first embodiment of the present invention.
A mobile phone 1 as a mobile terminal device is similar to a general mobile phone in that an antenna 11, a radio circuit 12, a voice control circuit 13, a microphone 14, a speaker 15, a display 16, a display control circuit 17, a keyboard 18, and a key operation circuit 19 are used. And the control part 20 which controls these is provided.

  The cellular phone 1 according to this embodiment is configured to compare the password formed and the input password with the GPS (Global Positioning System) unit 30 that specifies the current position of the cellular phone 1 by communication with at least three artificial satellites. When there is an incoming call in the password mode 40 to be performed, in the drive mode, a message notification unit 21 that notifies the other party that the vehicle is in operation and prompts the message to be input, and when a message is input A message storage unit 22 for storing the message and a mode switching unit 23 for switching the mode of the mobile phone 1 between the drive mode and the standby mode are provided.

  The GPS unit 30 includes an antenna 31 that receives radio waves from a satellite, a GPS circuit 32 that calculates a current position from the received radio waves, a measurement time by a built-in timer, and a change amount of the position calculated by the GPS circuit 32 (movement) The moving speed calculating unit 33 for calculating the moving speed from the distance), and whether the moving speed obtained by the moving speed calculating unit 33 is larger or smaller than a preset threshold (for example, 20 km / h) And a moving speed determination unit 34 for determining

  The password unit 40 includes a password forming unit 41 that forms a password when an incoming call is received when the moving speed determining unit 34 determines that the moving unit is moving at high speed, and a password and password forming unit input by the user. A password comparison unit 42 for comparing with the password formed at 41 and determining whether or not the two passwords match.

The operation of the mobile phone 1 having the above configuration will be described with reference to the flowchart of FIG.
Simultaneously with turning on (starting) the power, the mobile phone 1 enters a standby mode, which is a basic mode (step S101), and calculates a moving speed (step S102).
The moving speed is calculated by the moving speed calculator 33 of the GPS unit 30. Then, the moving speed determination unit 34 determines whether the calculated moving speed is larger or smaller than a preset threshold value (for example, 20 km / h) (step S103).
If the moving speed determining unit 34 determines that the moving speed is greater than the threshold value, the control unit 20 outputs a command signal to the mode switching unit 23 to switch to the drive mode. Thereby, the mode of the mobile phone 1 is switched from the standby mode to the drive mode (step S104).

On the other hand, if the moving speed determination unit 34 determines that the threshold value is equal to or less than the threshold value, the control unit 20 outputs a command signal to the mode switching unit 23 so as to cancel the drive mode. As a result, the drive mode is canceled (step S112).
If the mobile phone 1 is in the standby mode immediately after the power is turned on, the standby mode is maintained in step S112.
When the drive mode is canceled in step S112, the control unit 20 refers to the message storage unit 22 and searches for a message that has not been reproduced yet (step S113). And when there is a message, it alert | reports that there is a message or reproduces | regenerates a message (step S114).

When there is an incoming call (step S105), the control unit 20 determines whether or not the current mode is set to the drive mode (step S106). If the drive mode is not set, the control unit 20 permits the call (step S107). ).
If the drive mode is set, the password forming unit 41 forms a password, displays the password on the display 16, and prompts the user to input the same password (step S108). The password formed by the password forming unit 41 may be random alphanumeric characters or the telephone number of the other party, but if the user is driving, stop driving and watch the display screen It may be a plurality of characters, figures, symbols, or a combination thereof that can only be entered.

Also, a different password may be formed each time so that the user does not store the password.
If the password is not entered before the incoming call rings for a preset number of times (for example, 10 times) (step S109), the other party is notified that “I am driving now. Please record the message” and the message Recording is prompted (step S111).

In addition, when a password is input before the preset number of rings, the password comparison unit 42 compares the input password with the password displayed on the display 16 to determine whether or not they match. Is determined (step S110). If they do not match, it is notified that “I am driving now. Please record the message” and prompts the recording of the message (step S111). If they match, the call is permitted (step S107).
When the above procedure is completed, the process returns to step S102 again, and the processes of steps S102 to 104, steps 112, S113, and S114 are repeated at a constant time interval (for example, every several seconds) until the next incoming call is received.

[Second Embodiment]
A second embodiment of the present invention will be described with reference to the block diagram of FIG.
In this embodiment, a short-distance two-way wireless communication technology (for example, Bluetooth (registered trademark)) that connects terminal devices wirelessly at a short distance is used.
That is, the mobile phone 1 of this embodiment includes a short-distance bidirectional wireless communication unit 50 including an antenna 51 and a communication module 52 in addition to the units shown in FIG.
When a short-distance two-way wireless communication unit is mounted on a vehicle-side device, for example, a navigation device, communication between both devices is possible only by bringing the mobile phone 1 'close to the navigation device.

In the example shown in FIG. 3, the navigation device 60 on the vehicle side includes a navigation control circuit 63, a GPS antenna 68, a GPS circuit 67, a monitor 66, an antenna 61 for short-distance two-way wireless communication, and a communication module 62. have. In this example, the short-distance bidirectional wireless communication antenna 61 and the communication module 62 constitute a short-distance bidirectional wireless communication unit such as Bluetooth (registered trademark).
With the above configuration, the mobile phone 1 ′ can directly obtain the vehicle speed information from the vehicle-side navigation device 60.

Next, the operation of the second embodiment will be described with reference to the flowchart of FIG.
The mobile phone 1 ′ enters a standby mode simultaneously with power-on (start) (step S121), and at the same time searches for devices that can be connected to the short-distance two-way wireless communication unit 50 in the vicinity (step S122). . If there is a connectable device, it is determined whether speed information is available from the device (step S123). If the speed information is available, the speed information is obtained and it is determined that the vehicle is being boarded (step S124).
Thereafter, if the moving speed is higher than 20 km / h (step S125), the drive mode is automatically set (step 104). The subsequent processing is the same as in the previous embodiment.

In addition, when there is no device that can be connected to the short-distance two-way wireless communication unit 50 in the vicinity (step S122), or when speed information is not available from the device (step S123), the vehicle is not necessarily on board. Therefore, the moving speed is calculated from the GPS information of the mobile phone 1 '(step S126), and it is determined whether or not the moving speed is 20 km / h or more (step S125). Thereafter, the processes after step S104 or step S112 are executed.
In the second embodiment described above, it is possible to specify that the moving means is a vehicle by performing communication with a device provided in the vehicle, so that it is prevented from shifting to the drive mode when moving on a train or the like. There is an advantage that usability can be improved.

[Third embodiment]
Next, a third embodiment of the present invention will be described with reference to the flowchart of FIG. 5 and the graph of FIG.
This embodiment can be applied to the cellular phones 1 and 1 'having the configuration of either the first embodiment or the second embodiment.
Simultaneously with power-on (start), the mode of the mobile phone is basically set to the standby mode (step S131).
When there is an incoming call or when the user performs any operation on the mobile phone for the purpose of answering the incoming call, sending it, reading the mail, etc. (step S132), the moving speed is obtained from the GPS unit 50 or the navigation device 60. (Step S133), it is determined whether the moving speed is larger or smaller than a preset threshold value (for example, 20 km / h) (Step S134). As a result, when the moving speed is larger than the threshold value, the mode of the mobile phone is set to the drive mode (step S135), and a password is formed and displayed to prompt the user to input (step S136).

If a password is not entered within a certain period of time, for example, a certain number of calls at the time of an incoming call (step S137), or a password is not entered within a certain time (between the number of calls). However, if the displayed password and the entered password do not match (step S138), the other party is informed that “I am driving now. Please record the message” and prompt the recording of the message (step S139).
If the comparison results in step S138 indicate that the two match, a call or the like (incoming response, transmission, mail browsing, etc.) is permitted (step S143).
After the call ends (step S144), it is searched whether there is a message due to a past incoming call (step S145), and if there is a message, this is notified or the message is reproduced (step S146).

  On the other hand, if it is determined in step S134 that the moving speed is equal to or less than the threshold value (20 km / h), the change in the past moving speed is checked, and the past fixed time (considering the waiting time for signals and crossings) For example, it is determined whether or not there is a moving speed greater than the threshold value (20 km / h) within 3 minutes (step S142). Therefore, the mobile phone of this embodiment includes a memory that stores a speed history for the past several minutes (in this case, at least 3 minutes).

  In this embodiment, even if the moving speed is equal to or less than the threshold (20 km / h), by examining the past moving speed history, whether the vehicle is temporarily stopped due to waiting for a signal or waiting for a crossing, It is possible to determine whether it is a continuous stop due to parking or the like. And if there is a moving speed greater than the threshold (20 km / h) within a certain past time (for example, 3 minutes), the current situation is a temporary stop due to a signal, a railroad crossing wait, etc. Judgment is made and the drive mode is set (step S135). When the moving speed of the threshold value (20 km / h) or less continues beyond the predetermined time (3 minutes), a call or the like is permitted (step S143).

Although preferred embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments.
For example, in the above description of the first embodiment, the drive mode setting is limited to when there is an incoming call. It is also possible to configure so that the drive mode is set when any key operation is performed.
Moreover, although the threshold value of the moving speed is 20 km / h as an example, any other moving speed can be used as long as it can reliably determine the driving of the vehicle, and 15 km / h to 30 km / h. It is preferable to set within the range of h.

  Further, in the above description, the position measurement system has been described as a global positioning system (GPS) that determines the global position by receiving radio waves from at least three satellites. A position measurement system that determines the current position by receiving the radio wave from may be used.

  The present invention can be applied not only to mobile phones but also to other mobile terminal devices such as mobile terminals and PDAs. Further, the present invention can be applied to the use restriction of the mobile terminal device not only in the vehicle but also in any vehicle such as an aircraft or a ship.
