FIG. 3 is a schematic explanatory diagram illustrating an example of control by the control unit of the mobile terminal illustrated in FIG. 1.

  Embodiments of the present invention will be described with reference to the drawings.

  A smartphone 11 as a mobile terminal according to an embodiment of the present invention and an in-vehicle device 12 connected to the smartphone 11 by wireless communication are configured as shown in FIG.

  In FIG. 1, a smartphone 11 includes a communication unit 15 for wireless connection with an Internet line, a GPS reception unit 16 that receives radio waves from an artificial satellite to acquire position information, WiFi communication with an in-vehicle device 12, or A short-range communication unit 17 that performs short-range wireless communication such as Bluetooth communication, a storage unit 18 (ROM, RAM, etc.) that can store various kinds of information such as music information, a display unit 20 including an LCD, and a display unit An operation unit 21 for inputting information formed in a touch panel format on 20 and a control unit 22 (CPU or the like) connected to these to control each unit are configured.

  Various information such as music information stored in the storage unit 18 of the smartphone 11 (including information obtained via the Internet), programs, and the like can be provided to the in-vehicle device 12 via the short-range communication unit 17. . For example, the music stored in the storage unit 18 can be output as voice by the in-vehicle device 12. Further, the in-vehicle device 12 can execute the program stored in the storage unit 18.

  The in-vehicle device 12 includes a processing unit 31 that includes a computer unit (for example, a CPU, a ROM, a RAM, an I / O interface, a bus, and the like). The processing unit 31 includes an AV unit 32 capable of reproducing various sound sources and video sources (for example, CD and DVD) and a navigation unit 35 capable of navigating the host vehicle (GPS receiver, gyro sensor, acceleration sensor, etc.) In addition, as described above, the short-range communication unit 34 for short-range wireless communication with the smartphone 11 is connected. The processing unit 31 is connected to an output circuit 37 that is connected to the speaker 36. As a result, an audio signal related to processing by the AV unit 32 and the navigation unit 33 can be output from the speaker 36. Further, as described above, music information provided from the smartphone 11 connected by short-range wireless communication can be output from the speaker 36. In addition, the processing unit 31 includes a storage unit 38 (for example, a hard disk, a flash memory, etc.) capable of storing various information such as music information and map information used in the AV unit 32 and the navigation unit 33, and an LCD. A display unit 39 that displays video and the like associated with various processes to be performed and an operation unit 35 that can input instructions necessary for various processes formed in a touch panel format on the display unit 39 are connected. The operation unit 35 may be a push button type hard key instead of the touch panel type soft key. Further, both a touch panel type and a push button type can be used as the operation unit 35.

  In the above-described smartphone 11 (mobile terminal), for example, processing is performed according to the procedure shown in FIG. Hereinafter, the above procedure will be described with reference to FIG. 2 (FIGS. 1 and 3 as appropriate). FIG. 3 is a specific example of the procedure of FIG. 2, and shows a positional relationship between an in-vehicle device 12 mounted on the vehicle and a smartphone 11 (portable terminal) possessed by an occupant who goes from the home to the golf course with the vehicle 51. Is.

  In FIG. 2 and FIG. 3, when getting on the vehicle 51 from home and going to the golf course, the occupant manually operates in order to connect the in-vehicle device 12 (power ON state) and the occupant's smartphone 11 by short-range wireless. Thus, the communication function of the smartphone 11 is activated (communication function ON) (S11). At this time, the control part 22 determines whether the smart phone 11 and the vehicle equipment 12 have already performed the pairing process (registration of connection object) (S12). When the pairing process has already been completed (YES in S12), the smartphone 11 is connected to the in-vehicle device 12 by short-range wireless communication (WiFi communication or Bluetooth communication) by the activation of the communication function of the smartphone 11 described above (S11). Connected (S14). If the pairing process has not been performed yet (NO in S12), the short-range wireless connection is established by performing the pairing process. As the pairing process, for example, the short-range wireless communication function of the smartphone 11 and the vehicle-mounted device 12 is activated, and the pairing process is completed by an operation of selecting a device to be connected (the smartphone 11 and the vehicle-mounted device 12). (S14). When the connection by the short-range wireless is made, the music can be output from the speaker 36 of the in-vehicle device 12 based on the music information stored in the storage unit 18 of the smartphone 11, for example. Specifically, as shown in FIG. 3, while traveling from the home toward the golf course by the vehicle 51, as described above, the smartphone 11 and the in-vehicle device 12 mounted on the vehicle 51 are connected by short-range radio. Thus, various information can be transmitted from the smartphone 11 to the in-vehicle device 12, displayed on the screen of the display unit 39, and output from the speaker 36.

  Next, the control unit 22 detects whether or not the short-range wireless connection has been disconnected (S15: wireless communication disconnection detection means). For example, as shown in FIG. 3, when the vehicle 51 arrives at the parking lot of the golf course and stops the engine of the vehicle 51, the power of the in-vehicle device 12 is turned off, and the short-range wireless between the smartphone 11 and the in-vehicle device 12 is Disconnected. When detecting short-distance wireless disconnection with the in-vehicle device 12 (YES in S15: wireless communication disconnection detecting means), the control unit 22 acquires disconnection position information indicating the position of the smartphone 11 when the wireless communication is disconnected. (S16: Position information acquisition means). The control unit 22 calculates position information (coordinate information) indicating the position of the smartphone 11 at the time of cutting by using radio waves from the artificial satellites (plural) received by the GPS receiving unit 16 and obtains it as position information at the time of cutting. The control unit 22 stores the cutting position information in the storage unit 18. When short-distance radio disconnection is not detected (NO in S15), the short-distance radio is connected as it is (for example, when traveling from the home to the golf course in FIG. 3 and being connected).

  The control unit 22 calculates and acquires position information indicating the position of the smartphone 11 with a radio wave from the artificial satellite received by the GPS receiving unit 16 every elapse of a preset predetermined time (S17: position information acquisition unit). . The predetermined time set in advance can be set, for example, about every 1 to 2 minutes or the like, but can be set according to the application.

  The control unit 22 determines whether or not the position of the smartphone 11 indicated by the acquired position information is within a predetermined range of the position of the smartphone 11 indicated by the position information at the time of cutting (S18: position determination means). The predetermined range of the position of the smartphone 11 indicated by the above-described disconnection position information is normally a range that can be connected by short-range wireless communication, but can be a wider and narrower range. Since the range in which connection is possible differs between WiFi communication and Bluetooth communication, it is preferable to set the predetermined range for each type of short-range wireless communication to be connected. As an example, as shown in FIG. 3, a range around the vehicle 51 (indicated by a chain line) can be used.

  When it is determined that the position of the smartphone 11 indicated by the acquired position information is not within the predetermined range of the position of the smartphone 11 indicated by the position information at the time of cutting, that is, outside the predetermined range (S18: NO) Then, the short-range wireless communication function of the smartphone 11 is stopped (OFF) (S19). Thereby, since the consumption of the electric power used in the near field communication function ON state (standby state) of WiFi etc. is suppressed, the electrical storage of the battery of the smart phone 11 can be made lasting. Even if the short-range wireless communication function is stopped, since the power of the smartphone 11 is in the ON state, functions such as the Internet and a telephone call are operating. In the specific example of FIG. 3, when the vehicle arrives at the golf parking lot and the engine of the vehicle 51 is stopped, the power of the in-vehicle device 12 is turned off, and the near field communication is disconnected. Since the smartphone 11 carried by the occupant leaves the vehicle 51 together with the occupant and goes out to the golf course, it is within a predetermined range (shown by a chain line) in the position indicated by the position information at the time of cutting (the parking position of the vehicle 51 at the golf parking lot). The range of the short range communication function of the smartphone 11 is stopped by the control unit 22.

  Next, when the smartphone 11 returns from the golf course to the vehicle 51 parked in the golf parking lot together with the occupant, the position of the smartphone 11 indicated by the position information acquired at that time is the position of the smartphone 11 indicated by the position information at the time of cutting. It becomes within the predetermined range (within the range indicated by the chain line in FIG. 3), and the control unit 22 determines that it is within the predetermined range (S18: YES). Based on the determination of being within the predetermined range, the control unit 22 activates (ON) the near field communication function of the smartphone 11 (S20). Thereby, when the engine of the vehicle 51 is operated and the power source of the in-vehicle device 12 is turned on, the smartphone 11 is connected to the in-vehicle device 12 by short-range communication without requiring a manual connection operation, Transmission and reception are possible between each other.

  When the power of the smartphone 11 is turned off, the control unit 22 ends the operation of the present embodiment (the procedure illustrated in FIG. 2). However, when the power of the smartphone 11 is on, the control unit 22 repeatedly repeats a short distance. When the presence / absence of communication disconnection is detected and disconnection is detected, position information at the time of disconnection indicating the position of the smartphone 11 at the time of disconnection is acquired, and the position of the smartphone 11 indicated by the position information acquired at every elapse of a predetermined time is predetermined. It is determined whether it is within the range, and the communication function is stopped or started (S15 to S19). Thereby, for example, when the vehicle is parked at the store parking lot when the customer stops at the store on the way back from the golf course, the short-range communication is cut off by turning off the power of the in-vehicle device 12. And if the smart phone 11 moves toward the store from the vehicle 51, since it will come out from the predetermined range, the function of near field communication will stop. Thereafter, when returning to the vehicle 51, the short range communication function is activated within the predetermined range, and the smart phone 11 is connected to the in-vehicle device 12 by short-range wireless when the in-vehicle device 12 is turned on.

  In this way, when the in-vehicle device 12 mounted on the vehicle and the smartphone 11 (mobile terminal) possessed by the vehicle occupant are connected by short-range wireless communication (such as WiFi communication or Bluetooth communication), Since the short-range wireless communication function of the smartphone 11 that is away from the position (the position indicated by the position information at the time of disconnection) beyond a predetermined range (short-range wireless communication possible range) is stopped, useless storage of the battery of the smartphone 11 is wasted Can be prevented. After that, the smartphone returns to the vehicle together with the occupant, and the short-range wireless communication function of the smartphone 11 is activated when it is within a predetermined range from the position of the vehicle, and when the in-vehicle device 12 is turned on, the smartphone 11 and the in-vehicle device 12 are close to each other. Since it connects wirelessly, the connection operation with the smart phone 11 is not required and the convenience improves.

  In the above-described embodiment, when the short-range wireless communication with the in-vehicle device 12 is disconnected and is outside the predetermined range of the position indicated by the position information at the time of disconnection, the short-range wireless communication function of the smartphone 11 is stopped, Although the short-range wireless communication function is activated when it falls within the range, the short-range wireless communication function of the smartphone 11 may be stopped at the same time as the short-range wireless communication with the in-vehicle device 12 is disconnected. However, when it is desired to activate immediate short-range wireless communication within the vehicle after disconnection, the communication function is stopped because it is located within the predetermined range. Therefore, it is necessary to activate the communication function of the smartphone 11. Therefore, it is preferable to stop the short-range wireless communication function when it is out of the predetermined range after disconnection.

  In the present embodiment, WiFi communication or Bluetooth communication is exemplified as the short-range wireless communication, but the present invention is not limited to this. Moreover, although the smart phone is used as a portable terminal, it is not limited to this. A mobile terminal other than a smartphone may be used as long as the mobile terminal can communicate with an in-vehicle device by short-range wireless communication. The in-vehicle device may be any device that can communicate with the portable terminal through near-rejection radio.

  As described above, according to the present invention, when the in-vehicle device and the portable terminal are connected by short-range wireless communication, the short-range wireless communication of the portable terminal that is away from the in-vehicle device beyond a predetermined range. Since the function is stopped, it is possible to prevent wasteful use of the power stored in the mobile terminal, which is useful as a mobile terminal connected to an in-vehicle device mounted on the vehicle by wireless communication.
