According to the present invention, a characteristic configuration of a mobile terminal device including a communication unit capable of performing short-range wireless communication with a wireless communication device included in a mobile object is the self-location information that is information on the own location. A position information acquisition unit; a connection monitoring unit that monitors a connection state of a communication link between the communication unit and the wireless communication device; and the communication unit is in a communicable state, and the communication link is provided by the connection monitoring unit. When the disconnection of the communication link is detected, a storage unit that stores the position indicated in the self-location information when the disconnection of the communication link is detected as the disconnection position information, and the communicable state of the communication unit A communication state control unit that controls to one of the communication cut-off states, and after the disconnection of the communication link is detected by the connection monitoring unit, the own position indicated in the own position information is indicated in the cut position information. Pre-position When the distance closer than the first determination distance is less than the second determination distance set below the first determination distance, and the own position indicated in the own position information is the cut position information. A return determination that determines that the vehicle has returned in both cases when a predetermined time has passed and is less than the second determination distance after being separated from the indicated position by at least the second determination distance. And the communication state control unit sets the communication unit to a communicable state when the communication unit is in a communication cut-off state when it is determined by the return determination unit to return. It is in.

According to said characteristic structure, when the communication link between the radio | wireless communication apparatus with which a mobile body is equipped, and the communication part with which a portable terminal device is equipped is cut | disconnected, the cutting position which is the own position information at the time of the said cutting | disconnection Storing, using the distance from the cutting position to the current position of the mobile terminal device and the predetermined first determination distance and the second determination distance, to the position where the mobile terminal device is away from the cutting position After moving, it can be appropriately determined that it has returned (returned) to the vicinity of the cutting position. And when it determines with the portable terminal device having returned to the said cutting | disconnection position vicinity, the state of a communication part can be automatically made into a communicable state. As a result, even if the user of the mobile terminal device sets the state of the communication unit to the communication cut-off state after the communication link is disconnected, the state of the communication unit is automatically changed when returning to the vicinity of the disconnection position. It can be in a communicable state. Therefore, it is not necessary for the user to manually perform an operation for switching the state of the communication unit to the communicable state. Therefore, convenience for the user can be improved.
In addition, when the second determination distance is set to be smaller than the first determination distance, the threshold value for determining return to the vicinity of the cutting position is set to be smaller than the threshold value for determining that the second determination distance is away from the cutting position. Therefore, it is possible to suppress the occurrence of the hunting phenomenon when performing control for setting the state of the communication unit to the communicable state when the mobile terminal device approaches less than the second determination distance. Note that the configuration of the present invention includes the case where the first determination distance is equal to the second determination distance.

  According to this configuration, since the communication link is disconnected while the movement of the mobile body is stopped, the stop position of the mobile body is substantially equal to the disconnection position of the communication link. Therefore, even if the mobile terminal device moves away from the stop position of the mobile unit and sets the communication state of the communication unit to the communication cut-off state, the communication state of the communication unit is automatically changed only by returning to the vicinity of the stop position of the mobile unit. It can be in a communicable state.

  Further, it is preferable that the wireless communication device is mounted on a vehicle as the moving body and has a function of disconnecting the communication link in conjunction with the main power supply of the vehicle being turned off.

  According to this configuration, since the communication link is disconnected in conjunction with the main power supply of the vehicle being turned off, the stop position (main power off position) of the vehicle and the disconnection position are substantially equal. . Therefore, even if the user leaves the stop position of the vehicle and sets the communication state of the communication unit to the communication cut-off state, the communication state of the communication unit is automatically changed to the communicable state only by returning to the vicinity of the stop position of the vehicle. can do.

In the present embodiment, the communication state control unit 7 determines the command and transmission from the connection monitoring unit 6, the input reception unit 10, and the return determination unit 8, and the state of the communication unit 4 when the command and transmission are received. Based on this, the state of the communication unit 4 is controlled. Specifically, when the communication state control unit 7 receives a notification from the connection monitoring unit 6 that the communication link between the communication unit 4 and the wireless communication apparatus 101 is detected to be disconnected, Information of the communication unit 4 is output to the connection monitoring unit 6, and if the communication unit 4 is in a communicable state, the communication unit 4 is controlled to be in a communication cut-off state. In other words, if the communication unit 4 is in a communicable state when the connection monitoring unit 6 detects the disconnection of the communication link, the communication state control unit 7 sets the communication unit 4 in a communication cut-off state. In addition, if the communication state control unit 7 receives from the connection monitoring unit 6 the notification that the communication link disconnection has been detected, the communication state control unit 7 receives a notification from the input reception unit 10. Unless there is a command, the state of the communication unit 4 is maintained in the communication cut-off state.

  The communication state control unit 7 controls the state of the communication unit 4 according to the operation input received by the input receiving unit 10. Specifically, when the user performs an operation input for setting the state of the communication unit 4 to the communication cut-off state via the input receiving unit 10, the communication state control unit 7 sets the communication unit 4 to the communication cut-off state. If the communication unit 4 is in a communicable state, the communication unit 4 is controlled to be in a communication cut-off state, and the communication unit 4 is in a communication cut-off state when the command is received. If so, control is performed to maintain the state. On the other hand, when the user performs an operation input for setting the state of the communication unit 4 to the communicable state via the input receiving unit 10, the communication state control unit 7 sets the communication unit 4 to the communicable state. If a command is received from the input receiving unit 10 and the state of the communication unit 4 at that time is a communication cut-off state, the communication is possible, and if the state of the communication unit 4 when the command is received is a communication cut-off state, that state Control to maintain.

  Furthermore, when the communication unit 4 is in the communication cut-off state when it is determined that the return determination unit 8 has returned, the communication state control unit 7 sets the communication unit 4 in a communicable state. Specifically, when the determination result indicating that the communication state control unit 7 has returned from the return determination unit 8 is transmitted, if the state of the communication unit 4 when the determination result is acquired is the communication cut-off state, The communication unit 4 is controlled so as to be in a communicable state. In addition, if the communication unit 4 is in a communicable state when the determination result indicating that it has returned from the return determination unit 8 is acquired, the communication state control unit 7 is configured to maintain the communicable state. 4 is controlled.

  The return determination unit 8 is based on the cut position M1 that is the own position of the mobile phone 1 when the communication link between the mobile phone 1 and the navigation device 100 is cut off, and the current own position M2 of the mobile phone 1. This is a functional unit that determines that the mobile phone 1 has returned to the vicinity of the cutting position M1 after a certain distance from the cutting position M1. Specifically, after the disconnection of the communication link between the communication unit 4 and the wireless communication device 101 is detected by the connection monitoring unit 6, the return determination unit 8, as shown in FIG. The second position set to be equal to or less than the first determination distance L1 after the own position M2 indicated in the information is separated from the position (cutting position M1) indicated in the cutting position information 21 by a predetermined first determination distance L1 or more. This is a functional unit that determines that it has returned when it approaches less than the determination distance L2. Then, the return determination unit 8 performs the determination process, the first distance determination unit 12 that determines that the own position M2 of the mobile phone 1 is more than the first determination distance L1 from the cutting position M1, A second distance determination unit that determines that the own position M2 of the mobile phone 1 is closer than the second determination distance L2 from the cutting position M1; Here, the magnitudes of the first determination distance L1 and the second determination distance L2 are set in advance at the time of shipment, or set by a user or the like. In the present embodiment, the second determination distance L2 (for example, 3 m) is set to be smaller than the first determination distance L1 (for example, 6 m), but the present invention is not limited to this. Since 2nd determination distance L2 which concerns on this invention should just be the distance below 1st determination distance L1, 2nd determination distance L2 and 1st determination distance L1 may be the same. The first determination distance L1 and the second determination distance L2 that are set in advance are stored in a storage medium such as the storage unit 3. And the 1st distance determination part 12 and the 2nd distance determination part 13 match | combine the starting point of the 1st determination distance L1 and the 2nd determination distance L2 with the cutting position information, when performing the following comparison determination process.

  In the present embodiment, the first distance determination unit 12 is a distance L (hereinafter simply referred to as a current position M2 of the mobile phone 1 from the cut position M1 that is the own position of the mobile phone 1 when the communication link is disconnected). The distance L) to the own position M2 is compared with the first determination distance L1, and the determination process is performed. In this determination process, the first distance determination unit 12 calculates a linear distance connecting the coordinate position (latitude and longitude) of the cutting position M1 and the coordinate position (latitude and longitude) indicating the own position M2 of the mobile phone 1. The calculated linear distance L is compared with the first determination distance L1. The second distance determination unit 13 performs the determination process similarly. Further, in the present embodiment, the return determination unit 8 includes the own position information periodically acquired by the own position information acquisition unit 5 (specifically, the own position acquired after the instruction from the connection monitoring unit 6). Information) is sequentially input. The first distance determination unit 12 acquires the cutting position information 21 from the storage unit 3 when the own position information starts to be input from the own position information acquisition unit 5. Then, the first distance determination unit 12, based on the cutting position information 21 acquired from the storage unit 3 and the own position information that is periodically input, as shown in FIG. It is determined whether or not the position M2 is more than a predetermined first determination distance L1 (for example, 6 m) from the cutting position M1. That is, the first distance determination unit 12 determines whether or not the distance L to the own position M2 is equal to or greater than a predetermined first determination distance L1 (for example, 6 m). If the first distance determination unit 12 determines that the distance L from the cutting position M1 to the own position M2 is equal to or greater than the first determination distance L1, the first distance determination unit 12 transmits information to that effect to the second distance determination unit 13. . Thereafter, determination processing by the second distance determination unit 13 is performed. On the other hand, when the distance L from the cutting position M1 to the own position M2 is smaller than the predetermined first determination distance L1, the first distance determining unit 12 determines that the own position M2 of the mobile phone 1 is the cutting position. The above process is repeated until the first determination distance L1 is separated from M1.

  When the second distance determination unit 13 receives a notification from the first distance determination unit 12 that the own position M2 of the mobile phone 1 is more than the first determination distance L1 from the cutting position M1, the cutting position information is stored from the storage unit 3. 21 is acquired. The second distance determination unit 13 determines a distance L to the own position M2 in advance based on the cutting position information 21 and the own position information periodically input from the own position information acquisition unit 5. It is determined whether it is less than the second determination distance L2 (for example, 3 m). When the second distance determination unit 13 determines that the distance L to the own position M2 is less than the predetermined second determination distance L2, that is, the own position M2 of the mobile phone 1 is changed from the cutting position M1. When it is determined that the distance is less than the second determination distance L2, the determination result is transmitted to the communication state control unit 7. On the other hand, when the distance L to the own position M2 is equal to or greater than the second determination distance L2, the second distance determining unit 13 determines that the own position M2 of the mobile phone 1 is the second predetermined from the cutting position M1. If it is determined that the distance is greater than or equal to the determination distance L2, the above process is repeated until the position M2 of the mobile phone 1 approaches less than the second determination distance L2. In the present embodiment, the wireless communication device 101 enters a communication cutoff state in conjunction with the vehicle stopping and the main power supply of the vehicle being turned off, and the communication link between the communication unit 4 and the wireless communication device 101 is established. Since it is cut, the cutting position M1 corresponds to the stop position of the vehicle. Therefore, the return determination unit 8 in the present embodiment substantially confirms that the user holding the mobile phone 1 has returned to the vicinity of the stopped vehicle after leaving a certain distance from the stopped vehicle. Judgment.

  The deletion processing unit 9 is a functional unit that executes a deletion process of data stored in the storage unit 3. In the present embodiment, when the deletion processing unit 9 receives a notification from the connection monitoring unit 6 that the reconnection is detected after the communication link between the communication unit 4 and the wireless communication apparatus 101 is disconnected. The cutting position information 21 stored in the storage unit 3 is deleted. In other words, if the communication link between the communication unit 4 and the wireless communication apparatus 101 is connected after it is determined that the return determination unit 8 has returned, the cutting position information 21 stored in the storage unit 3 is stored. delete. In addition, when the own position information acquisition unit 5 stores the own position information acquired periodically as a movement history in the storage unit 3, the deletion processing unit 9 uses the own position information after the cutting position information. Thus, the movement history of the self-location information that is periodically acquired and stored until the communication that the communication link is reconnected from the connection monitoring unit 6 may be deleted.

  The input receiving unit 10 is a functional unit that receives an operation input for switching the state of the communication unit 4 between a communicable state and a communication cut-off state. Specifically, when receiving an operation input for switching the state of the communication unit 4 between a communicable state and a communication cut-off state from the user, the input reception unit 10 communicates a command based on the content of the operation input. This is performed to the state control unit 7. For example, when an operation input for changing the state of the communication unit 4 from the user to the communication cut-off state is received, a command for changing the state of the communication unit 4 to the communication cut-off state is output to the communication state control unit 7. The input receiving unit 10 in the present embodiment is based on a display device such as a liquid crystal display device, an input device such as a touch panel, and a program that displays an input receiving operation unit on the display device and sets an input receiving area of the touch panel. It is configured. Then, the user touches or slides his / her finger on whether to turn each function ON or OFF on the setting screen of the communication function such as the Bluetooth function or the infrared function displayed on the display device. By selecting, an operation input can be performed.

1-4. Procedure of Operation Processing Next, referring to FIG. 2, until the communication link between the navigation device 100 and the mobile phone 1 executed in the mobile phone 1 according to the present embodiment is disconnected and reconnected. The processing procedure will be described. The processing procedure described below is executed by hardware and / or software (program) or both constituting each functional unit of the mobile phone 1 described above. When each of the above function units is configured by a program, the arithmetic processing device included in the mobile phone 1 operates as a computer that executes the program that configures each of the above function units.

  When the connection monitoring unit 6 detects that the communication link between the navigation device 100 and the mobile phone 1 has been disconnected (step # 01), the local position information acquisition unit 5 detects when the communication link has been disconnected. The self-location information of the mobile phone 1 is acquired, the self-location information is stored in the storage unit 3 as the cutting position information 21 (step # 02), and the self-location of the mobile phone 1 periodically acquired from the GPS receiving unit 11 Output of information to the return determination unit 8 is started. When the first distance determination unit 12 acquires the current own position information of the mobile phone 1 from the own position information acquisition unit 5 (step # 03), the first distance determination unit 12 acquires the cutting position information 21 from the storage unit 3, and uses these, A distance L from the cutting position M1 to the current position M2 of the mobile phone 1 is calculated. Then, the first distance determination unit 12 determines whether or not the calculated distance L to the own position M2 is equal to or greater than a predetermined first determination distance L1 (step # 04). When the first distance determination unit 12 determines that the distance L to the self position M2 is equal to or greater than the first determination distance L1 (step # 04: Yes), the second distance determination unit 13 performs the self position information acquisition unit. 5, the latest location information of the location information of the mobile phone 1 input to the sequential return determination unit 8 is acquired as the current location information (step # 05). Then, the second distance determination unit 13 acquires the cutting position information 21 from the storage unit 3, and uses the current own position information of the mobile phone 1 acquired in step # 05 and the cutting position information 21 to perform the cutting. A distance L from the position M1 to the current position M2 of the mobile phone 1 is calculated. Next, the second distance determination unit 13 determines whether or not the calculated distance L from the cutting position M1 to the own position M2 is less than a predetermined second determination distance L2 (step # 06). ). When the second distance determination unit 13 determines that the distance L to the own position M2 is less than the second determination distance L2 (step # 06: Yes), the communication state control unit 7 can communicate with the communication unit 4. (Step # 07). Then, when the connection monitoring unit 6 detects that the communication link between the communication unit 4 and the wireless communication device 101 has been reconnected, that is, the communication link between the navigation device 100 and the mobile phone 1 is reconnected. When it is detected (step # 08: Yes), the deletion processing unit 9 deletes the cutting position information 21 stored in the storage unit 3 (step # 09). When the first distance determination unit 12 determines that the distance L to the own position M2 is less than the first determination distance L1 (step # 04: No), the process returns to step # 03, and the mobile phone 1 Re-acquire current location information. If the second distance determination unit 13 determines that the distance L to the own position M2 is equal to or greater than the second determination distance L2 (step # 06: No), the process returns to step # 05, and the mobile phone 1 Re-acquire current location information. Further, after the communication state control unit 7 controls the communication unit 4 to be in a communicable state (step # 07), the connection monitoring unit 6 reconnects the communication link between the communication unit 4 and the wireless communication device 101. If this is not detected (step # 08: No), the process of step # 08 is repeated until reconnection is detected.

2. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. The mobile phone 41 according to the present embodiment basically has the same configuration as that of the first embodiment, except that it includes a timer 47 and the return determination unit 43 further includes a time determination unit 46. This is different from the first embodiment. Hereinafter, the configuration of the mobile phone 1 according to the present embodiment will be described focusing on differences from the first embodiment. Note that points not particularly described are the same as those in the first embodiment.

  As shown in FIG. 4, the mobile phone 41 in the present embodiment includes a timer 47 in addition to the configuration of the mobile phone 1 of the first embodiment. The timer 47 is a functional unit that measures time, and is referred to by the time determination unit 46 in the return determination unit 43. In the present embodiment, the distance L from the cut position M1 that is the mobile phone 41's own position when the communication link between the navigation device 100 and the mobile phone 41 is cut to the current own position M2 of the mobile phone 41. However, after the first distance determination unit 44 determines that the distance is less than the first determination distance L1, the second distance determination unit 45 measures time from the time when the second distance determination unit 45 determines that the distance is greater than or equal to the second determination distance L2. Start. In addition, the timer 47 determines when the second distance determination unit 45 determines that the distance L to the own position M2 is less than the second determination distance L2, or the first distance determination unit 44 to the own position M2. When the distance L is determined to be greater than or equal to the first determination distance, the time measurement is terminated. That is, the timer 47 measures the time during which the mobile phone 41 stays in an area that is greater than or equal to the second distance and less than the first distance from the cutting position M1.

  Similarly to the first embodiment, the return determination unit 43 detects the disconnection of the communication link between the communication unit 4 and the wireless communication device 101 by the connection monitoring unit 6, and then uses the self-location information of the mobile phone 41. The second determination distance that is set to be equal to or less than the first determination distance L1 after the indicated position M2 is separated from the position (cutting position M1) indicated by the cutting position information 21 by a predetermined first determination distance L1 or more. In addition to being a function unit that determines that it has returned when it is less than L2, it has the following functions. The return determination unit 43 passes the predetermined time (predetermined time T) in a state where the current position M2 of the mobile phone 41 is more than the second determination distance L2 from the cutting position M1 indicated in the cutting position information 21. Thereafter, it is determined that the vehicle has returned even when approaching less than the second determination distance L2. In other words, in the present embodiment, the return determination unit 43 determines that the current position M2 of the mobile phone 41 is not less than the second determination distance L2 and less than the first determination distance L1 from the cutting position M1 for a predetermined time T. When (for example, 15 minutes) elapses and then approaches less than the second determination distance L2, it is determined that the vehicle has returned. Then, the return determination unit 43 includes a first distance determination unit 44 that determines whether or not the own position M2 of the mobile phone 41 is more than the first determination distance L1 from the cutting position M1 in order to execute the determination process. The mobile phone 41 includes a second distance determination unit 45 that determines whether or not the own position M2 of the mobile phone 41 is closer than the second determination distance L2 from the cutting position M1, and a time determination unit 46 (described later). The first determination distance L1, the second determination distance L2, and the predetermined time T are set at the time of shipment, or set in advance by a user or the like and stored in a storage medium such as the storage unit 3.

  The first distance determination unit 44 in the present embodiment has substantially the same configuration as the first distance determination unit 12 in the first embodiment. However, when the first distance determination unit 12 of the first embodiment determines that the distance L to the own position M2 is equal to or greater than the first determination distance L1, information indicating that is the second distance determination. However, if it is determined that the distance is smaller than the first determination distance L1, the mobile phone 1 is not transmitted to the second distance determination unit 13, and the mobile phone 1 determines that its own position M2 is the first determination from the cutting position M1. It was the structure which repeats the said determination process until it leaves | separates more than the distance L1 (step # 05: No of FIG. 2). In other words, when it is determined that the distance is smaller than the first determination distance L1, the second distance determination unit 13 is not transmitted. However, the first distance determination unit 44 in the present embodiment, regardless of whether the distance L to the own position M2 is equal to or greater than the first determination distance L1 or less than the first determination distance L1. The determination result at 44 is transmitted to the second distance determination unit 45.

  When the second distance determination unit 45 receives the determination result from the first distance determination unit 44, the second distance determination unit 45 changes the process to be executed according to the determination result of the first distance determination unit 44. In the first embodiment, the second distance determination unit 13 is used only when the distance L to the own position M2 in the first distance determination unit 12 is equal to or greater than the first determination distance L1. Because the configuration is not transmitted from the server, there is only one process to be executed. Therefore, all the processes performed by the second distance determination unit 13 are the same. In this regard, the second distance determination unit 45 and the second distance determination unit 13 of the present embodiment are different configurations. Specifically, when the determination result that the distance L to the own position M2 is equal to or greater than the first determination distance L1 is transmitted from the first distance determination unit 44, the second distance determination unit 45 In order to perform the same processing as in the first embodiment, the current location information of the mobile phone 41 is newly acquired. Since the subsequent processing is the same as that in the first embodiment, description thereof is omitted here. On the other hand, when the determination result that the distance L from the first distance determination unit 44 to the own position M2 is less than the first determination distance L1 is transmitted, the second distance determination unit 45 transmits the first implementation described above. Processing different from the form is performed.

  Hereinafter, the different processing will be described. When the determination result that the distance L from the first distance determination unit 44 to the own position M2 is less than the first determination distance L1 is transmitted, the second distance determination unit 45 determines in the first distance determination unit 44 Whether the distance L to the own position M2 is less than a predetermined second determination distance L2 (for example, 3 m) using the own position information and the cutting position information 21 of the mobile phone 41 used in the process. Determine whether or not. When the second distance determination unit 45 determines that the distance L to the own position M2 is equal to or greater than the second determination distance L2, that is, the own position M2 of the mobile phone 41 is changed from the cutting position M1 to the first determination distance L1. If the distance is less than the second determination distance L2, the time determination unit 46, which will be described later, determines whether or not the time that is less than the first determination distance L1 and more than the second determination distance L2 exceeds the predetermined time T. To perform the determination process. Then, the second distance determination unit 45 receives information from the time determination unit 46 that the time that is less than the first determination distance L1 and more than the second determination distance L2 exceeds the predetermined time T. Thereafter, the same processing (step # 15 and step # 16 in FIG. 5) as the processing (step # 05 and step # 06 in FIG. 2) of the second distance determination unit 13 in the first embodiment is executed. To do. On the other hand, if the second distance determination unit 45 determines that the own position M2 of the mobile phone 41 is less than the second determination distance L2 from the cut position M1, the own position M2 of the mobile phone 41 is once from the cut position M1. Since there is a high possibility that the distance is not more than the second determination distance, the process is returned to the first distance determination unit 44.

  The time determination unit 46 determines the time during which the distance L from the cutting position M1 to the current position M2 of the mobile phone 41 is less than the first determination distance L1 and greater than or equal to the second determination distance L2, that is, the mobile phone 41 It is a functional unit that determines whether or not the time for staying at a position that is less than the first determination distance L1 and greater than or equal to the second determination distance L2 from the cutting position M1 is greater than a predetermined time T. In this embodiment, when the time determination unit 46 receives a command to execute the time determination process from the second distance determination unit 45, the time determination unit 46 causes the timer 47 to start measuring time and refers to the timer 47, The time measured by the timer 47 is compared with the predetermined time T. When the time determination unit 46 determines that the time measured by the timer 47 has exceeded the predetermined time T, information to that effect is transmitted to the second distance determination unit 45. Then, the second distance determination unit 45 performs the same processing as the second distance determination unit 13 of the first embodiment. That is, when the predetermined time T has elapsed in a state where the distance L to the own position M2 is less than the first determination distance L1 and equal to or greater than the second determination distance L2, the distance L to the own position M2 is determined to be the first determination. Even if the distance is not more than the distance L1, the subsequent processing is the same as the case where the distance is equal to or more than the first determination distance L1. When the time determination unit 46 determines that the time measured by the timer 47 does not exceed the predetermined time T, the process returns to the first distance determination unit 44. This is because the own position M2 of the mobile phone 41 may be in the middle of moving toward a position that is more than the first determination distance L1 from the cutting position M1.

  Thus, in this embodiment, even if the distance from the cutting position M1 to the own position M2 of the mobile phone 41 is not equal to or greater than the first determination distance L1, it is equal to or greater than the second determination distance L2 and the first determination distance L1. If the predetermined time T has elapsed, the second distance determination unit 45 treats the distance L to the own position M2 as the second determination distance. It is determined whether it is less than L2. Thereby, when the user who has the mobile phone stays at a position that is greater than or equal to the first determination distance and less than the second determination distance from the cutting position M1, and then returns to a position that is less than the second determination distance, for example, Even if the vehicle is parked in the garage of the house and the user holding the mobile phone stays in a house close to the garage (for example, a house whose distance from the garage is less than the first determination distance) When riding in a vehicle, the communication unit 4 can be appropriately brought into a communicable state. That is, when the user stays in the area between the second determination distance L2 and the first determination distance L1, the state of the communication unit can be controlled by time, so the first determination distance L1 and the second determination distance L1 It is possible to set a large difference from the determination distance L2.

2-2. Procedure of Operation Process Next, referring to FIG. 5, until the communication link between the navigation device 100 and the mobile phone 41 executed in the mobile phone 41 according to the present embodiment is disconnected and reconnected. The processing procedure will be described. The operation from step # 11 to step # 19 corresponds to step # 01 to step # 09 in the first embodiment, and will be described only briefly here. That is, Step # 20 and Step 21, which are parts added in the present embodiment, will be mainly described.

  When the connection monitoring unit 6 detects that the communication link between the navigation device 100 and the mobile phone 41 has been disconnected (step # 11), the local position information acquisition unit 5 detects when the communication link is disconnected. The own position information of the mobile phone 41 is acquired (step # 12). When the first distance determination unit 44 acquires the current own position information of the mobile phone 41 from the own position information acquisition unit 5 (step # 13), the distance L to the own position M2 is a predetermined first determination distance. It is determined whether or not L1 or more (step # 14). When the first distance determination unit 44 determines that the distance L to the own position M2 is equal to or greater than the first determination distance L1 (step # 14: Yes), the second distance determination unit 45 determines that the current mobile phone 41 is present. Own position information is newly acquired (step # 15). And the 2nd distance determination part 45 determines whether the distance L to the own position M2 is less than the predetermined 2nd determination distance L2 (step # 16). When the second distance determination unit 45 determines that the distance L to the own position M2 is less than the second determination distance L2 (step # 16: Yes), the communication state control unit 7 can communicate with the communication unit 4. (Step # 17). When the connection monitoring unit 6 detects that the communication link between the communication unit 4 and the wireless communication device 101 has been reconnected, that is, the communication link between the navigation device 100 and the mobile phone 41 is reconnected. When it is detected (step # 18: Yes), the deletion processing unit 9 deletes the cutting position information 21 stored in the storage unit 3 (step # 19). After the communication state control unit 7 controls the communication unit 4 to be in a communicable state (step # 17), the connection monitoring unit 6 reconnects the communication link between the communication unit 4 and the wireless communication apparatus 101. If it is not detected (step 18: No), the process of step # 18 is repeated until reconnection is detected. The operation processing so far is the same processing as in the first embodiment. Hereinafter, the operation processing that is a feature of the present embodiment will be described.

  When the first distance determination unit 44 determines that the distance L to the own position M2 is less than the first determination distance L1 (step # 14: No), the second distance determination unit 45 performs the own position M2. Is determined to be less than the second determination distance L2 (second determination distance L2 or more) (step # 20). When the second distance determination unit 45 determines that the distance L to the own position M2 is equal to or greater than the second determination distance L2 (step # 20: No), the timer 47 starts measuring time. Then, the time determination unit 46 compares the time measured by the timer 47 with a predetermined time T, and determines whether or not the time measured by the timer 47 exceeds the predetermined time T ( Step # 21). Then, when the time determination unit 46 determines that the time measured by the timer 47 exceeds the predetermined time T (step # 21: Yes), the time determination unit 46 determines the second distance determination information to that effect. Transmitted to the unit 45. Then, when the predetermined time T has passed in a state where the distance L to the own position M2 is less than the first determination distance and greater than or equal to the second determination distance, the distance L to the own position M2 is equal to or more than the first determination distance. Therefore, the process returns to step # 15, and the second distance determination unit 45 acquires the latest own position information (step # 15). Thereafter, as described above, the processing after step # 16 is performed. If the second distance determination unit 45 determines in step # 20 that the distance is less than the second determination distance L2 (step # 20: Yes), the own position M2 of the mobile phone 41 is still once from the cutting position M1. Since there is a possibility that the distance is not more than the second determination distance L2, in this case, the process is returned to the first distance determination unit 44. That is, returning to step # 13, the first distance determination unit 44 acquires the current new self-location information (step # 13). In step # 21, if the time determination unit 46 determines that the time measured by the timer 47 does not exceed the predetermined time T (step # 21: No), the own position M2 of the mobile phone 41 is The distance from the cutting position M1 is more than the second determination distance L2, but it has not reached the first determination distance L1, that is, it is in the middle of moving toward the position more than the first determination distance L1. Therefore, the process returns to the first distance determination unit 44. That is, returning to step # 13, the first distance determination unit 44 acquires the current new self-location information (step # 13).

3. Other Embodiments Finally, other embodiments of the mobile terminal device according to the present invention will be described. Note that the configurations disclosed in the following embodiments can be applied in combination with the configurations disclosed in other embodiments as long as no contradiction arises.

(1) In the above embodiment, the communication unit 4 is in a communicable state and the wireless communication device 101 is in a communication cut-off state in conjunction with the main power supply of the vehicle being turned off. The description has been given using the example in which the communication link by the short-range communication between the mobile phone 1 and the navigation device 100 is disconnected. That is, the description has been given using the example in which the communication link is disconnected from the navigation device 100 side. However, the embodiment of the present invention is not limited to this. For example, a case where the communication link is disconnected because the navigation apparatus 100 and the mobile phone 1 are separated to a position where short-range wireless communication cannot be performed and a communication partner is not found is also included in the embodiment of the present invention. For example, the mobile phone 1 is held when the wireless communication device 101 is in a communicable state due to the main power supply of the stopped vehicle or the navigation device 100 being in an on state, and the communication unit 4 is in a communicable state. In some cases, the communication link is disconnected when the user is away until the radio wave of the short-range wireless communication does not reach the vehicle. Even in such a case, it is often considered that the own position (disconnection position) when the disconnection of the communication link is detected by the connection monitoring unit 6 and the position where the vehicle is stopped can be regarded as substantially the same position. . Therefore, the determination that the user (mobile phone 1) has returned to the vicinity of the cutting position by the return determination unit 8 corresponds to the determination that the user has returned to the vicinity of the stopped vehicle. Therefore, when the user approaches the vehicle, the communication unit 4 is automatically in a communicable state, and the user does not need to manually switch the state of the communication unit 4 to the communicable state. It can be omitted.

(2) In the above embodiment, the return determination unit 8 obtains the distance between the cutting position M1 and the mobile phone 1 through the GPS receiving unit 11 and stores the cutting position M1 (latitude Longitude) and a straight line distance connecting the mobile phone 1's own position M2 (latitude / longitude) acquired via the GPS receiver 11 is calculated, and the straight line distance and the first determination distance L1 and the first The second determination distance L2 is compared. However, the present invention is not limited to this. For example, as shown in FIG. 3, a concentric area having a radius of the first determination distance L1 and the second determination distance L2 centered on the cutting position M1 is set, and the return determination unit 8 and the GPS reception unit 11 It is also possible to make a configuration in which it is determined whether or not the mobile phone 1 has returned to the vicinity of the cutting position M1 by comparing with the own position M2 of the mobile phone 1 obtained through the above. Specifically, an area having a radius within the second determination distance is set as the second area (inner circle portion in FIG. 3), and an area within the circle having the radius of the first determination distance and excluding the second area is the first area. (The outer circle part covering the second area in FIG. 3), the area outside the first area from the cutting position M1 (the side away from the cutting position M1) is the third area, and the position M2 of the mobile phone 1 is It is also possible to adopt a configuration for determining whether or not the vehicle has returned based on whether it is included in the area. For example, when the own position M2 of the mobile phone 1 moves to the third area and then enters the second area, the return determination unit 8 determines that the mobile phone 1 has returned.

  (3) In the above embodiment, the communication unit 4 automatically shuts down communication via the communication state control unit 7 if it is in a communicable state when the connection monitoring unit 6 detects the disconnection of the communication link. It was the structure controlled so that it might be in a state. However, the embodiment of the present invention is not limited to this. For example, even if the communication unit 4 is in a communicable state when the connection monitoring unit 6 detects the disconnection of the communication link, the communication unit 4 does not automatically enter the communication cut-off state, but the input receiving unit 10 from the user. A configuration may be adopted in which the communication is cut off by an operation input via.
