Description

  The present invention relates to a mobile terminal system, a mobile terminal, and a program.

  In collection and delivery operations such as home delivery, various mobile terminals are often used. For example, a delivery driver uses a handy terminal, a mobile phone, a credit card payment terminal, or the like.

  In recent years, composite portable terminals in which these functions are integrated into one handy terminal have been developed. The home delivery driver uses this portable terminal to make a voice call with the management center and the customer, or deliver a package using a bar code scanner or a credit card payment function. When delivery is performed, various information is periodically transmitted to the management center via the mobile terminal. The management center manages information transmitted from the mobile terminal and instructs the delivery driver to re-deliver.

  Delivery drivers who operate mobile terminals often receive re-delivery notices from customers and calls from management centers during driving. For safety reasons, it is forbidden to drive a car while holding a mobile terminal in hand. The home delivery driver had to stop the vehicle one by one when there was an incoming call while driving. When driving on an expressway or the like where the vehicle cannot be stopped, the delivery driver cannot answer the incoming call.

  According to the portable terminal equipped with the hands-free function, the delivery driver can make an incoming call response without holding the portable terminal while driving. The home-delivery driver can make a call (hands-free call) while holding the handle of the vehicle with both hands by connecting the portable terminal to the hands-free device and switching the portable terminal to a predetermined mode.

Patent Document 1 describes a wireless call system that switches from a hands-free call to a handset call by an operation on an ignition switch of an automobile, and then easily switches from a handset call to a hands-free call.
In Patent Document 2, it is detected that a mobile phone terminal is present in the vehicle based on a radio wave condition of the mobile phone terminal that the user has brought into the vehicle, and that the user is driving when the user is driving. Describes a technique for performing a hands-free incoming call when an incoming call is received.
Patent Document 3 describes a technology related to an automobile telephone device that allows a vehicle driver to make a hands-free call without performing a switching operation when a call signal is input to a portable terminal while the vehicle is running. Yes.

  However, in order to make a hands-free call on the mobile terminal, it is necessary to perform a switching operation. If the driver forgets the operation, there is a possibility that an incoming call response cannot be made during driving. With the technique described in Patent Document 1, switching for making a hands-free call can be easily performed, but switching operation by the user is required. In the technique described in Patent Document 2, switching for making a hands-free call can be performed automatically, but the in-vehicle unit cannot be put into a state for making a hands-free call. It is not possible to automatically cancel the free call state. In the technique described in Patent Document 3, when there is an incoming call while the vehicle is traveling, it is possible to shift to the hands-free mode, but a switching operation is required.

  An object of the present invention is to make it possible to reliably control a voice call depending on whether a portable terminal is in a vehicle and whether the vehicle is moving.

FIG. 3 is a flowchart showing a mobile terminal mode change process executed by the CPU 1 of the mobile terminal H. The portable terminal mode change process is executed in cooperation with the CPU 1 and the program stored in the memory 2.

  First, as shown in FIG. 3, when a power-on instruction for the portable terminal H is input from the numeric keypad 8 or the like, power is supplied from the power supply unit 9 to each unit (step S1). Based on the signal input from the connection detection circuit 12, it is determined whether or not the mobile terminal H is installed (connected) in the in-vehicle unit U (step S2).

  When it is determined that it is installed (step S2; YES), each part of the mobile terminal H is changed to the hands-free mode (step S3), and the process ends.

  When it is not determined that it is installed (step S2; NO), it is determined whether or not a beacon is received from the in-vehicle unit U via the communication unit 10 (step S4). Details of the processes in steps S4 to S7 will be described later (see FIG. 7). If it is not determined that it has been received (step S4; NO), the process returns to step S4, and it is determined whether or not a beacon has been received again via the communication unit 10.

  When it is determined that it has been received (step S4; YES), it is determined whether or not there is an in-vehicle unit U that can be connected by referring to the memory 2 based on the received beacon information (step S5). If it is not determined that there is a connectable in-vehicle unit U (step S5; NO), the process returns to step S5, and whether there is a connectable in-vehicle unit U with reference to the memory 2 based on the beacon information received again. It is determined whether or not.

  When it is determined that there is a connectable in-vehicle unit U (step S5; YES), communication between the mobile terminal H and the in-vehicle unit U by the communication unit 10 is established (step S6). Next, it is determined whether or not the mobile terminal H has been brought into the vehicle based on a communication response result by the communication unit 10 (step S7).

  If it is determined that the vehicle has been brought into the vehicle (step S7; YES), a vehicle movement detection process is executed (step S8).

  FIG. 4 is a flowchart showing the movement detection process A executed in step S8. In the movement detection process A, the movement of the vehicle is detected by signals from the acceleration sensor 11 and the GPS 10e.

  As shown in FIG. 4, first, the current time and the position of the mobile terminal H are set (step S81). Specifically, the time stored in the memory 2 is read out and developed in the RAM of the memory 2 together with the position information acquired by the GPS 10e.

  After step S81, the acceleration sensor 11 and the GPS 10e are executed in parallel.

  First, as a process of the acceleration sensor 11, it is determined whether or not a change in acceleration is detected by the acceleration sensor 11 (step S82). More specifically, the determination is made based on whether or not the acceleration of a preset value (for example, 1 G or more) determined in the memory 2 has changed.

  If it is determined that a change in acceleration has been detected (step S82; YES), it is determined whether the acceleration has changed continuously (step S83). For example, the determination is made based on whether or not a change in acceleration equal to or greater than a set value has continued for a predetermined time or more.

  If it is not determined that a change in acceleration has been detected (step S82; NO), or if it is not determined that the acceleration has changed continuously (step S83; NO), the process returns to step S82, and the acceleration sensor 11 changes the acceleration again. Whether or not is detected is determined.

  On the other hand, in the GPS 10e, it is determined whether or not the position information has changed (step S84). Specifically, the position information is updated every predetermined cycle (for example, 1 second), and the determination is made based on whether or not the memory 2 has changed by a predetermined value (such as 5 m or more).

  When it is determined that the position information has changed (step S84; YES), it is determined whether the position information has changed continuously (step S85). For example, the determination is made based on whether or not a change greater than the set value has been continuously detected for 5 seconds or more. In addition, the determination result of step S82-S85 is suitably transmitted with respect to the vehicle-mounted unit U via the communication part 30, and the vehicle-mounted unit U receives the determination result of the vehicle movement in the portable terminal H suitably.

  If it is not determined that the position information has changed (step S84; NO), or if it is not determined that the position information has changed continuously (step S85; NO), the process returns to step S84 to determine whether the position information has changed again. Is judged.

  When it is determined that the acceleration has changed continuously (step S83; YES), or when it is determined that the position information has changed continuously (step S85; YES), the in-vehicle unit received via the communication unit 10 It is determined whether or not the vehicle movement determination result (see FIG. 6 described later) coincides with U (step S86).

  When it is not determined that they match (step S86; NO), the process returns to step S82 and step S84, and it is determined whether or not a change in acceleration is detected by the acceleration sensor 11, and whether or not the position information has changed in the GPS 10e. Is judged.

  When it is determined that they match (step S86; YES), a return value indicating that the vehicle is moving is returned (step S87).

Returning to FIG. 3, it is determined whether or not the vehicle is moving based on the return value of the process in step S8 (step S9).
If it is not determined that the vehicle has been brought into the vehicle (step S7; NO), or if it is not determined that the vehicle is moving (step S9; NO), the process returns to step S7 to determine again whether the vehicle is moving. The

  When it is determined that the vehicle is moving (step S9; YES), each part of the mobile terminal H is changed to the hands-free mode (step S10), and the process ends.

  FIG. 5 is a flowchart showing the in-vehicle unit mode change process executed by the CPU 21 of the in-vehicle unit U. The in-vehicle unit mode change process is executed in cooperation with the CPU 21 and the program stored in the memory 22.

  First, as shown in FIG. 5, when an instruction to turn on the vehicle unit U (power on) is input from the switch 27 or the like, power is supplied from the power supply unit 28 to each unit of the vehicle unit U (step S21). ). Based on the signal input from the connection detection circuit 31, it is determined whether or not the mobile terminal H is installed (connected) in the in-vehicle unit U (step S22).

  When it is determined that it is installed (step S22; YES), each part of the in-vehicle unit U is changed to the hands-free mode (step S23), and the process ends.

  When it is not determined that it is installed (step S22; NO), a beacon is transmitted to the mobile terminal H via the communication unit 29 (step S24). Details of the processing in steps S24 to S27 will be described later (see FIG. 7). Next, it is determined whether there is a connectable mobile terminal H by receiving a response from the mobile terminal H to the transmitted beacon via the communication unit 29 (step S25). If it is not determined that there is a connectable mobile terminal H (step S25; NO), the process returns to step S25, and it is determined whether there is a connectable mobile terminal H again.

  When it is determined that there is a connectable mobile terminal H (step S25; YES), a communication mode between the mobile terminal H and the in-vehicle unit U by the communication unit 29 is established (step S26). Next, it is determined whether or not the mobile terminal H has been brought into the vehicle based on the communication response result by the communication unit 29 (step S27).

  When it is determined that the vehicle has been brought into the vehicle (step S27; YES), a vehicle movement detection process is executed (step S28).

  FIG. 6 is a flowchart showing the movement detection process B executed in step S28. In the movement detection process B, the movement of the vehicle is detected by signals from the acceleration sensor 30a, the GPS 29e, the gyro sensor 30b, and the vehicle speed sensor 30c.

  As shown in FIG. 6, first, the stop time and position are set (step S281).

  After step S281, the processes of the acceleration sensor 30a, the GPS 29e, the gyro sensor 30b, and the vehicle speed sensor 30c are executed in parallel. In addition, the determination result in step S282 to step S289 described later is appropriately transmitted to the mobile terminal H via the communication unit 29, and the mobile terminal H receives the determination result of the in-vehicle unit U.

  Since the processing from step S282 to step S285 is the same as the processing from step S82 to step S85, respectively, description thereof will be omitted.

  In the gyro sensor 30b, it is determined whether or not the angular velocity has changed (step S286). Specifically, the determination is made based on whether or not the angular velocity equal to or higher than a preset value (1 deg / s or the like) predetermined in the memory 22 has changed. When it is determined that the angular velocity has changed (step S286; YES), it is determined whether the angular velocity has changed continuously (step S287). For example, the determination is made based on whether or not the change in angular velocity equal to or greater than a set value has continued for a predetermined time.

  If it is not determined that the angular velocity has changed continuously (step S286; NO), or if it is not determined that the angular velocity has changed continuously (step S287; NO), the process returns to step S286, and whether the angular velocity has changed again. Is judged.

  The vehicle speed sensor 30c determines whether or not the vehicle speed pulse has changed (step S288). When it is determined that the vehicle speed pulse has changed (step S288; YES), it is determined whether the change in the vehicle speed pulse has been continuously counted (step S289). Specifically, a pulse corresponding to the vehicle speed detected by the vehicle speed sensor 29g is counted, and the determination is made based on whether or not it has continuously changed for a predetermined time or more.

  If it is not determined that the vehicle speed pulse has changed (step S288; NO), or if it is not determined that the change in vehicle speed pulse has been continuously counted (step S289; NO), the process returns to step S288, and the vehicle speed pulse has changed again. It is determined whether or not.

  When it is determined that the acceleration has changed continuously (step S283; YES), when it is determined that the position information has changed continuously (step S285; YES), it is determined that the angular velocity has changed continuously. In the case (step S287; YES), or when it is determined that the change in the vehicle speed pulse has been continuously counted (step S289; YES), whether or not the determination result of the mobile terminal H received via the communication unit 29 matches Is determined (step S290).

  If it is not determined that they match (step S290; NO), the process returns to step S282, step S284, step S286, and step S288.

  If it is determined that they match (step S290; YES), a return value indicating that the vehicle is moving is returned (step S291).

Returning to FIG. 5, it is determined whether or not the vehicle is moving based on the return value of the process in step S28 (step S29).
When it is not determined that the vehicle is brought into the vehicle (step S27; NO), when it is not determined that the vehicle is moving (step S29; NO), the process returns to step S27, and it is determined again whether or not the vehicle is moving. The

  When it is determined that the vehicle is moving (step S29; YES), each part of the in-vehicle unit U is changed to the hands-free mode (step S30), and the process ends.

  FIG. 7 is a ladder chart showing the exchange of data between the mobile terminal H and the in-vehicle unit U in steps S4 to S7 and steps S24 to S27. The portable terminal H and the vehicle-mounted unit U recognize each other's position by performing short-range communication. In the following description, the mobile terminal H and the in-vehicle unit U are described as communicating by PAN, but similar communication may be performed by other communication methods. That is, beacon transmission / reception and the like are not limited to communication by the PAN 10f and the PAN 29f, and similar communication may be executed by other devices constituting the communication unit 10 and the communication unit 29. For example, communication may be performed between the BT 10c and the BT 29c. In addition, communication (a so-called web beacon or the like) may be performed between the WWAN 10a and the WWAN 29a. The data access method between the portable terminal H and the in-vehicle unit U is a master / slave method, and the communication state between the portable terminal H and the in-vehicle unit U is constantly monitored by polling as will be described later. In the following example, the in-vehicle unit U functions as a master and the mobile terminal U functions as a slave, and the mobile terminal H responds to a request from the in-vehicle unit U.

  As shown in FIG. 7, the in-vehicle unit U reads various information (ID for identifying the in-vehicle unit U, channel used, signal strength, etc.) from the memory 22 with respect to the mobile terminal H in step S24 to read out the PAN 29f. Is transmitted with a beacon (step S101). This process is performed in step S24. These pieces of information are transmitted for each set value (for example, 100 milliseconds) determined in advance in the memory 22 of the in-vehicle unit U.

The in-vehicle unit U repeats the transmission in step S101 until there is a response from the mobile terminal H.
When the mobile terminal H receives a beacon from the in-vehicle unit U via the PAN 10f, the mobile terminal H refers to the ID of the in-vehicle unit U stored in the memory 2 and compares it with the received ID to determine whether the in-vehicle unit U is to be connected. to decide. If it is determined that the in-vehicle unit U is to be connected, an ID for identifying the mobile terminal H is attached and an ACK response is transmitted to the in-vehicle unit U (step S102). This ID is stored in the memory 2.

  When the in-vehicle unit U receives an ACK response from the portable terminal H via the PAN 29f, the in-vehicle unit U performs authentication by comparing the received ID of the portable terminal H with the ID stored in the memory 22, and the authentication result is obtained from the in-vehicle unit U. (Step S103). When the portable terminal H receives the authentication result via the PAN 10f, the portable terminal H transmits an ACK / NAK response to the in-vehicle unit U (step S104).

  Next, a signal of position power level (H) is transmitted from the in-vehicle unit U to the mobile terminal H via the PAN 29f (step S105). The position power level (H) is, for example, a transmission output within 10 m (an output signal indicating that the distance that the portable terminal H can receive radio waves is within 10 m from the in-vehicle unit). When the portable terminal H receives this signal via the PAN 10f, the portable terminal H adds information indicating reception sensitivity and transmits an ACK / NAK response to the in-vehicle unit U (step S106).

  Next, a signal of the position power level (M) is transmitted from the in-vehicle unit U to the mobile terminal H via the PAN 29f (step S107). The position power level (M) is, for example, a transmission output within 5 m (an output signal indicating that the distance that the mobile terminal H can receive radio waves is within 5 m from the in-vehicle unit). When the portable terminal H receives this signal via the PAN 10f, the portable terminal H attaches information indicating the reception sensitivity and transmits an ACK / NAK response to the in-vehicle unit U (step S108).

  Next, a signal of a position power level (L) is transmitted from the in-vehicle unit U to the mobile terminal H via the PAN 29f (step S109). The position power level (L) is, for example, a transmission output within 3 m (the distance at which the mobile terminal H can receive radio waves is within 3 m from the in-vehicle unit). When the portable terminal H receives this signal via the PAN 10f, the portable terminal H attaches information indicating reception sensitivity and transmits an ACK / NAK response to the in-vehicle unit U (step S110). In the present embodiment, when the mobile terminal H receives the position power level (L) via the PAN 10f, it is determined in step S7 that the mobile terminal H has been brought into the vehicle. Similarly, when the in-vehicle unit U receives an ACK response from the mobile terminal H via the PAN 29f, the in-vehicle unit U determines in step S27 that the mobile terminal H is brought into the vehicle. Whether or not it is brought into the vehicle may be determined according to the communication response result (in this embodiment, the response result of the position power level (L)), and is not limited thereto.

  Next, polling (step S111) and a transfer request are periodically performed between the PAN 29f of the in-vehicle unit U and the PAN 10f of the mobile terminal H (step S112), and the transfer request is confirmed and the communication state is confirmed. If communication between the in-vehicle unit U and the portable terminal H is connected, data transfer and ACK / NAK response are performed. The portable terminal H transmits ACK via the PAN 10f when data can be received from the in-vehicle unit U, and transmits NAK via the PAN 10f when reception is impossible. Similarly, when there is transmission data in response to the data transfer inquiry of the in-vehicle unit U, the mobile terminal H transmits an ACK through the PAN 10f, and transmits no NAK through the PAN 10f when there is no transmission data.

  FIG. 8 is a ladder chart showing data exchange between the mobile terminal H and the vehicle-mounted unit U when the hands-free mode is canceled. Similar to the ladder chart of FIG. 7, this data exchange is not limited to communication by PAN 10f and PAN 29f described below, and similar communication is executed by the communication unit 10 and other devices constituting the communication unit 29. It may be. The in-vehicle unit U monitors the response of the mobile terminal H to its own polling. When there is no response to polling more than the specified number of times, the position of the mobile terminal H is confirmed.

  As shown in FIG. 8, in the hands-free mode, polling is periodically performed between the PAN 29f of the in-vehicle unit U and the PAN 10f of the portable terminal H (step S201), and an ACK / NAK response is made (step S202). .

  When the ACK / NAK response is not returned from the mobile terminal H via the PAN 10f, the in-vehicle unit U transmits a position power level (H) signal from the in-vehicle unit U to the mobile terminal H via the PAN 29f ( Step S203). When the portable terminal H receives this signal via the PAN 10f, the portable terminal H transmits an ACK / NAK response to the in-vehicle unit U with information indicating reception sensitivity (step S204).

  Next, a signal of the position power level (M) is transmitted from the in-vehicle unit U to the mobile terminal H via the PAN 29f (step S205). When this signal is received, the portable terminal H adds information indicating reception sensitivity and transmits an ACK / NAK response to the in-vehicle unit U via the PAN 10f (step S206).

  Next, a signal of the position power level (L) is transmitted from the in-vehicle unit U to the portable terminal H via the PAN 29f (step S207). When the portable terminal H receives this signal via the PAN 10f, the portable terminal H attaches information indicating reception sensitivity and transmits an ACK / NAK response to the in-vehicle unit U (step S208). When the communication state at the position power level (L) is not established, the in-vehicle unit U determines that the mobile terminal H is outside the vehicle.

  When the response from the mobile terminal H is not returned, the in-vehicle unit U determines that the mobile terminal H is out of the radio wave range (out of service area) (step S209). If it is determined that the vehicle is out of service, the in-vehicle unit U is released from the hands-free mode and returns to the normal mode (beacon mode). Similarly, when the portable terminal H does not receive the position power level (L) signal via the PAN 10f, it is determined that the mobile terminal H is out of service area, the hands-free mode is canceled, and the voice call control is restored. In the present embodiment, it is assumed that the instruction from the in-vehicle unit U is prioritized for canceling the hands-free mode. For example, the mobile terminal H is out of range for a set value (for example, 10 seconds) predetermined in the memory 22 or more. If it is determined that there is no vehicle movement, it is canceled.

  Next, the in-vehicle unit U includes various information related to the in-vehicle unit U (ID for identifying the in-vehicle unit U, used channel, signal strength, etc.) in the beacon and transmits it to the mobile terminal H via the PAN 29f (step S210). . The in-vehicle unit U repeats this transmission until there is a response from the mobile terminal H.

  When receiving the beacon and various types of information from the in-vehicle unit U, the mobile terminal H attaches an ID for identifying the mobile terminal H and transmits an ACK response to the in-vehicle unit U via the PAN 10f (step S211).

  When the in-vehicle unit U receives an ACK response from the mobile terminal H via the PAN 29f, the in-vehicle unit U performs authentication by comparing the ID of the mobile terminal H with the ID stored in the memory 22, and the authentication result is sent to the in-vehicle unit U. Send. When receiving the authentication result, the mobile terminal H transmits an ACK / NAK response to the in-vehicle unit U via the PAN 10f.

  As described above, according to the mobile terminal system in the present embodiment, the voice output of the voice call is performed based on the communication output between the mobile terminal and the in-vehicle unit and the movement state of the vehicle detected by the mobile terminal and the in-vehicle unit. In order to control, the user can control the audio | voice output of both a portable terminal and a vehicle-mounted unit, without performing switching operation. After the audio output is controlled, the control can be canceled by the communication output between the portable terminal and the in-vehicle unit. By setting the audio output to the hands-free mode, the user does not need to perform a switching operation to the hands-free mode. Further, since the hands-free mode is canceled by the communication output, it is possible to prevent the user from forgetting to cancel the hands-free mode.

  In addition, by controlling the position power level transmitted from the in-vehicle unit, it is possible to easily detect the position of the mobile terminal by adjusting the communication output between the mobile terminal and the in-vehicle unit. In the portable terminal, it can be recognized whether or not the portable terminal is brought into the vehicle based on whether or not the controlled position power level is received.

  Note that the description in the present embodiment shows an example of the present invention, and the present invention is not limited to this. For example, the hands-free mode may be canceled when a predetermined condition is satisfied, or may not be canceled when the mobile phone is out of service area as in the present embodiment. For example, the hands-free mode may be canceled when it is determined that the mobile terminal is in the vehicle and it is determined that the vehicle has stopped.

  In addition, a known communication method such as BT or PAN may be used as a communication method between the mobile terminal H and the in-vehicle unit U in the hands-free mode.

  Further, vehicle position information and information related to vehicle movement may be acquired from the GPS of the in-vehicle car navigation system via the in-vehicle communication unit 29g.

  In addition, the detailed configuration and detailed operation of each device configuring the mobile terminal system according to the present embodiment can be changed as appropriate without departing from the spirit of the invention.
