  By the way, in the vehicle-mounted device disclosed in Patent Document 1 described above, since a plurality of portable terminal devices are connected, when a certain map application is activated and a map display or route guidance on this map is performed. Even if it is impossible to display a map using this map application due to the battery running out of the mobile terminal device, if the same or similar map application provided on another mobile terminal device is started, basically the same map display or route is displayed. Guidance can be made. However, in reality, if the map display is to be performed at the same display scale, it is necessary to set the display scale of the map display so far even in the map display by the newly started map application. In order to continue route guidance to the same destination, it is necessary to execute route search processing by designating the same destination in a newly activated map application. That is, when changing the mobile terminal device and using the same or similar map application, it is necessary to input information necessary for continuous use such as the display scale and the destination each time, and the operation becomes complicated. There was a problem that it took time to start using the same or similar apps.

  The present invention was created in view of the above points, and its purpose is to make the operation complicated when the portable terminal device is switched when the use becomes impossible or before the use becomes impossible. An object of the present invention is to provide an in-vehicle device capable of preventing this and reducing the time required for switching.

  In order to solve the above-described problem, the in-vehicle device according to the present invention is an in-vehicle device to which a portable terminal device can be connected via a connection unit, acquires a processing result of the portable terminal device, and displays the processing result. Change in the state of the first mobile terminal device that is executing the process, it is expected that it becomes difficult to acquire the processing result corresponding to the process being executed, or it is difficult to acquire the processing result Necessary for continuing the process of the first portable terminal device that has been executing processing until the switching timing is detected by the switching timing detecting means that detects the time as the switching timing and the switching timing detecting means. Using the continuation information acquisition means for acquiring continuation information from the first portable terminal device and the continuation information acquired by the continuation information acquisition means, the first portable terminal device that has been executing processing until then.

  As a result, it is difficult to obtain a processing result corresponding to the process being executed in the mobile terminal device, that is, when the mobile terminal device becomes unusable or before it becomes unusable, another mobile terminal device It becomes possible to switch the portable terminal device by continuing the processing at. In addition, since the continuation information necessary for continuation of processing is automatically acquired and inherited by the mobile terminal device after switching when switching the mobile terminal device, the operation at the time of switching is prevented from becoming complicated, The time required for switching can be shortened.

  Further, the processing content of the first mobile terminal device and the processing content of the second mobile terminal device described above are the same or similar, and the processing is interrupted in the first mobile terminal device by using the continuation information. It is desirable to continue the process in the second portable terminal device from the location. As a result, the same or similar processing can be continuously performed using a plurality of portable terminal devices.

  In addition, it is expected that the acquisition of the processing result detected as the switching timing described above will be difficult when the remaining amount of the battery mounted on the first portable terminal device becomes a predetermined value or less. It is desirable. This makes it possible to switch to another mobile terminal device before the battery runs out and continue processing.

  In addition, when it is difficult to obtain the processing result detected as the switching timing described above, it is desirable that the connection of the first portable terminal device via the connection unit is disconnected. Thereby, when the connection between the in-vehicle device and the mobile terminal device is disconnected, the processing can be continued by switching to another mobile terminal device.

  In addition, the processing performed by the first and second portable terminal devices described above involves transmission / reception of data by radio communication using radio waves with an external device, and acquisition of processing results detected as switching timings. When it is difficult, it is desirable that the radio communication is interrupted because the radio wave intensity is below a predetermined value. As a result, when wireless communication using radio waves between the mobile terminal device and the external device is interrupted due to a decrease in radio wave intensity, it is possible to switch to another mobile terminal device and continue processing. .

  Moreover, the process performed in the first and second portable terminal devices described above is at least one of a map display process performed by executing a map application and a route guidance process for guiding the travel route of the vehicle to the destination. It is desirable to be. Further, the continuation information acquired from the first portable terminal device by the continuation information acquisition unit described above includes information indicating the display scale at the time of map display, a destination necessary for route guidance processing, and a waypoint It is desirable that at least one of the information indicating the travel route to the waypoint and the destination is included. Thereby, it is possible to reliably continue the map display processing and the route guidance processing by switching to another mobile terminal device when the mobile terminal device that is executing the map application is unavailable.

  The display unit 16 is configured by an LCD (Liquid Crystal Display) or the like, and displays the operation content using the operation unit 14, the control content by the control unit 12 and the processing content (map display, etc.).

  The telephone processing unit 18 performs processing as a mobile phone. For example, the telephone processing unit 18 performs outgoing / incoming processing with a base station to perform telephone call processing, Internet connection processing, and the like.

  The memory 20 stores a control program executed by the control unit 12 and various application programs necessary when operating as a portable information terminal. In the present embodiment, a map application (hereinafter referred to as “map application”) 21 is stored which is an application program that performs navigation processing such as map display around the vehicle position, route search / guidance, intersection guidance (travel guidance), and the like. ing. In addition, in order to display a map around the vehicle position by executing the map application 21, it is necessary to acquire the position information of the mobile terminal device 10 </ b> A, and the control unit 12 stores the position information stored in the memory 20. This position information is acquired by executing a control program for acquisition. This position information acquisition is widely performed in current mobile phones with a GPS function, and is realized by receiving a signal from a GPS satellite and positioning the position.

  In addition, there are map data around the own vehicle position or around the own vehicle position to the destination, map data for performing intersection guidance, etc. in order to perform the above-described map display around the own vehicle position, route search, etc. Although necessary, in the present embodiment, map data necessary for the above processing is acquired from the map distribution server 90 each time.

Also good.

  The power supply circuit 24 is configured to include a secondary battery (or a dry battery that cannot be charged), and supplies operating power to each component in the mobile terminal device 10A.

  The mobile terminal device 10A described above activates the map application 21 in a state in which the in-vehicle device 50 is not connected, displays a map around the vehicle position on the display unit 16, or performs route search processing from the vehicle position. A travel route to a destination (set using the operation unit 14) can be obtained, or route guidance (travel guidance) can be performed along the travel route. In addition, when the in-vehicle device 50 is connected by wireless communication, when the start of the map application 21 is instructed from the in-vehicle device 50, a map necessary for map display, route guidance, and the like performed using the display unit 16 is provided. Data (drawing data necessary for display, travel route, data necessary for intersection guidance) can be sent to the in-vehicle device 50, and a similar map display or the like can be performed on the in-vehicle device 50 side.

  Similarly to the mobile terminal device 10A, the mobile terminal device 10B displays a map around the vehicle position by executing a map application, or performs a route search process to display a travel route from the vehicle position to the destination. It can be obtained or route guidance can be performed along this travel route. The mobile terminal device 10B basically has the same configuration as the mobile terminal device 10A, and detailed description thereof is omitted.

  In addition, the map application provided in each of the mobile terminal devices 10A and 10B is not necessarily the same, and it is only necessary to perform similar processing. For example, as long as the functions for performing map display and route guidance to guide the user to the destination are common, the content and display form of the displayed map image and intersection guide image may be different (this embodiment) In the form, such a state is referred to as “similar”).

  FIG. 2 is a diagram illustrating a detailed configuration of the in-vehicle device 50. As shown in FIG. 2, the in-vehicle device 50 includes a wireless communication unit 52, an operation unit 54, a display unit 56, a continuation information storage unit 58, and a control unit 60.

  The wireless communication unit 52 transmits and receives various data to and from the wireless communication unit 22 in the mobile terminal devices 10A and 10B via a wireless LAN. Note that wireless communication may be performed by a method other than the wireless LAN (for example, Bluetooth). Further, it is not always necessary to connect the mobile terminal devices 10A and 10B and the in-vehicle device 50 by wireless communication, and they may be connected to each other using a predetermined cable (in this case, wireless It is necessary to change the communication units 22 and 52 to a wired communication unit that can be connected via a predetermined cable).

  The operation unit 54 includes a numeric keypad, other keys, and various switches, and accepts user operation instructions and various inputs. Using the operation unit 54 configured with a touch panel, the user may point the numeric keypad displayed on the screen with a finger or the like.

  The display unit 56 is configured by an LCD (Liquid Crystal Display) or the like, and displays operation contents using the operation unit 54 and a map display based on map data sent from the mobile terminal device 10.

  The continuation information storage unit 58 stores necessary continuation information when taking over the processing of the mobile terminal device 10A to the mobile terminal device 10B. Details of the timing for taking over the process and the continuation information will be described later. The continuation information storage unit 58 is realized by a memory (not shown).

  The control part 60 is for controlling the whole vehicle-mounted apparatus 50, and is comprised including CPU. By executing a control program stored in a memory (not shown), the operation of each configuration shown below is realized. The control unit 60 includes a battery remaining amount acquisition unit 70, a connection determination unit 72, a radio wave intensity acquisition unit 74, a switching timing detection unit 76, a continuation information acquisition unit 78, a process continuation instruction unit 80, a map data acquisition unit 84, and a display process. A portion 86 is provided.

  The remaining battery level acquisition unit 70 acquires the remaining battery level of the mobile terminal devices 10A and 10B. As a specific example of the remaining battery level acquisition, in addition to the case where the remaining battery level acquisition unit 70 makes an inquiry to the control unit 12 in the mobile terminal devices 10A and 10B and acquires the control, the control in the mobile terminal devices 10A and 10B is performed. A case may be considered where the battery remaining amount is periodically notified from the unit 12 to the in-vehicle device 50 and acquired based on this notification.

  The connection determination unit 72 determines whether or not there is a connection by wireless communication between the wireless communication unit 52 and the wireless communication unit 22 of the mobile phone devices 10A and 10B.

  The radio wave intensity acquisition unit 74 acquires the radio wave state in the mobile terminal devices 10A and 10B, that is, the intensity of the radio wave transmitted from the base station. As a specific example of the acquisition of the radio wave intensity, as in the case of the acquisition of the remaining battery level, the radio wave intensity acquisition unit 74 makes an inquiry to the control unit 12 in the mobile terminal devices 10A and 10B and acquires the mobile phone. There may be a case where the control unit 12 in the terminal devices 10A and 10B periodically notifies the in-vehicle device 50 of the radio wave intensity and acquires it based on this notification.

  When the state of the mobile terminal device (for example, the mobile terminal device 10A) that is executing processing such as map display is changed, the switching timing detection unit 76 becomes difficult to obtain a processing result corresponding to the processing that is being executed. Alternatively, it is detected as a switching timing when it is expected that acquisition of the processing result will be difficult. Specifically, when a change occurs in the state of the mobile terminal device 10A that is executing the process and it becomes difficult to obtain a process result corresponding to the process that is being executed, the wireless communication connection is disconnected. The case corresponds to the case where the radio wave intensity in the mobile terminal device 10A becomes a predetermined value or less and the map data distributed from the map distribution server 90 cannot be received. Whether or not these cases apply is determined based on the determination result of the connection determination unit 72 or the radio wave intensity acquired by the radio wave intensity acquisition unit 74. Further, when it is expected that the state of the mobile terminal device 10A that is executing the process will change and it becomes difficult to obtain the processing result, the remaining amount of the battery mounted on the mobile terminal device 10A is predetermined. Applicable when the value falls below the value. Whether this is the case is determined based on the remaining battery level acquired by the remaining battery level acquisition unit 70.

  The continuation information acquisition unit 78 acquires continuation information necessary when processing (map display or the like) being executed in the mobile terminal device 10A is continued in the mobile terminal device 10B. As a specific example of the continuation information acquisition, in addition to the case where the continuation information acquisition unit 78 makes an inquiry to the control unit 12 in the mobile terminal device 10A and acquires it, the in-vehicle device 50 from the control unit 12 in the mobile terminal device 10A. For example, the continuation information is periodically notified and acquired based on this notification. The acquired continuation information is stored in the continuation information storage unit 58.

  Further, as described above, in the present embodiment, as processing performed in the mobile terminal devices 10A and 10B, a map display process performed by executing the map application 21 and a route that guides the travel route of the vehicle to the destination Guidance processing is assumed (one of these processes may be used). As a specific example of continuation information in this case, the map display processing includes information indicating the display scale at the time of map display. The route guidance process includes information indicating a destination necessary for route guidance and a route to the destination if there is a waypoint.

  The process continuation instructing unit 80 uses a continuation information acquired by the continuation information acquisition unit 78 and stored in the continuation information storage unit 58, and is a portable terminal different from the portable terminal device 10A that has been executing the process until then. The apparatus 10B is instructed to continue processing. Specifically, it is assumed that each process of the map display process and the route guidance process is being executed by the mobile terminal device 10A, and when the switching timing is detected by the switching timing detection unit 76, the process The continuation instruction unit 80 sends the continuation information stored in the continuation information storage unit 58 to the mobile terminal device 10B, and the same or similar processing (map display processing or route guidance processing) using this continuation information. Is instructed to execute. Receiving this instruction, the control unit 12 in the mobile terminal device 10B executes the map application 21 stored in the memory 20, and based on the continuation information, the map display processing of the same display scale, the same destination, and the waypoint The route guidance process along the travel route is continued.

  The map data acquisition unit 84 acquires map data (drawing data necessary for display, travel route, data necessary for intersection guidance) necessary for map display, route guidance, and the like as processing results from the mobile terminal devices 10A, 10B. .

  The display processor 86 uses the map data acquired by the map data acquisition unit 84 to display on the display unit 56 a map around the vehicle position, each image of a travel route necessary for route guidance and intersection guidance.

  The wireless communication unit 52 described above is a connection unit, the remaining battery level acquisition unit 70, the connection determination unit 72, the radio wave intensity acquisition unit 74, the switching timing detection unit 76 is a switching timing detection unit, and the continuation information acquisition unit 78 acquires continuation information. The processing continuation instruction unit 80 corresponds to the processing continuation instruction unit, the map data acquisition unit 84 corresponds to the processing result acquisition unit, the display processing unit 86 corresponds to the display processing unit, and the map distribution server 90 corresponds to the external device.

  The in-vehicle system of the present embodiment has such a configuration, and the operation will be described next. FIG. 3 is a flowchart showing an operation procedure of the in-vehicle device 50, and shows an operation procedure when switching to the mobile terminal device 10B when the remaining battery level of the mobile terminal device 10A decreases during the process.

  When the map display processing and the route guidance processing by the mobile terminal device 10A connected to the in-vehicle device 50 are started (step 100), the switching timing detection unit 76 determines that the remaining battery level acquired by the remaining battery level acquisition unit 70 is predetermined. It is determined whether or not the value has fallen below the value (step 102). Before starting the map display process or the like by the mobile terminal device 10A, it is necessary to determine the travel route to be route guidance by setting the scale of the map display or by searching the route with the destination or waypoint set. However, in the present embodiment, the focus is mainly on the switching operation of the mobile terminal devices 10A and 10B, and thus details thereof are omitted.

  If the remaining battery level is greater than the predetermined value, a negative determination is made in the determination in step 102, and the determination in step 102 is repeated. Further, when the remaining battery level is equal to or less than a predetermined value, an affirmative determination is made in the determination of step 102. Next, the continuation information acquisition unit 78 acquires continuation information necessary for continuing the processing of the mobile terminal device 10A, and stores it in the continuation information storage unit 58 (step 104).

  Thereafter, after the remaining battery level further decreases and the portable terminal device 10A runs out of battery (step 106), the process continuation instruction unit 80 starts connection with another portable terminal device 10B that can be connected (step 106). 108) It is determined whether or not the mobile terminal device 10B has a built-in map application capable of continuing processing (step 110). If the map application is not built in, a negative determination is made, and the process proceeds to an end process (step 112) for ending the map display process and the route guidance process that have been performed so far.

  If the mobile terminal device 10B has a built-in map application that can continue processing, an affirmative determination is made in step 110. Next, the process continuation instruction unit 80 instructs the portable terminal device 10B to continue the process using the continuation information stored in the continuation information storage unit 78 (step 114). Thereafter, map display processing and route guidance processing by the mobile terminal device 10B are started using the same display scale and travel route (step 116).

  FIG. 4 is a flowchart showing a modified example of the operation procedure of the in-vehicle device 50. The operation procedure in the case where the connection between the in-vehicle device 50 and the mobile terminal device 10A is disconnected during the processing and the operation is switched to the mobile terminal device 10B. It is shown. The operation procedure shown in FIG. 4 is different from the operation procedure shown in FIG. 3 in that steps 102, 104, and 106 are replaced with steps 120, 122, and 124. The explanation will be made with a focus on.

  When the map display process and the route guidance process are started by the mobile terminal device 10A connected to the in-vehicle device 50 (step 100), the continuation information acquisition unit 78 determines whether or not a certain time has passed (step 120). ) If not, a negative determination is made and this determination is repeated. If a certain time has elapsed, an affirmative determination is made in the determination of step 120. Next, the continuation information acquisition unit 78 acquires continuation information necessary for continuing the processing of the mobile terminal device 10A, and stores it in the continuation information storage unit 58 (step 122).

  Thereafter, the switching timing detection unit 76 determines whether or not the connection with the mobile terminal device 10A has been disconnected based on the determination result by the connection determination unit 72 (step 124). If the connection state is maintained, a negative determination is made, and the determination of the coincidence time elapse in step 120 is repeated. When the connection with the mobile terminal device 10A is disconnected, an affirmative determination is made in the determination in step 124, and then the process proceeds to step 108 to connect with the mobile terminal device 10B.

  FIG. 5 is a flowchart showing a modified example of the operation procedure of the in-vehicle device 50. During the processing, the radio wave state of the mobile terminal device 10A deteriorates, and the connection with the base station is cut off to become “out of service”. Therefore, an operation procedure for switching to the mobile terminal device 10B is shown. The operation procedure shown in FIG. 5 is different from the operation procedure shown in FIG. 3 in that steps 102, 104, and 106 are replaced with steps 130 and 132. In the following, attention is paid to each of these replaced steps. Will be described.

  When the map display processing and the route guidance processing by the mobile terminal device 10A connected to the in-vehicle device 50 are started (step 100), the switching timing detection unit 76 has the radio wave intensity acquired by the radio wave intensity acquisition unit 74 equal to or less than a predetermined value. It is determined whether or not it has decreased (step 130). By this determination, it is confirmed whether or not the radio wave state has deteriorated to such an extent that “out of service area” display indicating that communication is disabled is performed.

  If the radio wave intensity is stronger than the predetermined value, a negative determination is made in the determination in step 130, and the determination in step 130 is repeated. Further, when the radio field intensity becomes a predetermined value or less, an affirmative determination is made in the determination of step 130. Next, the continuation information acquisition unit 78 acquires continuation information necessary for continuing the processing of the mobile terminal device 10A and stores it in the continuation information storage unit 58 (step 132). Thereafter, the process proceeds to step 108 and connection with the mobile terminal device 10B is performed.

  As described above, in the in-vehicle device 50 according to the present embodiment, it is difficult to obtain a processing result corresponding to the process being executed in the mobile terminal device 10A, that is, when the mobile terminal device cannot be used or used. Before it becomes impossible, it becomes possible to continue the processing in another mobile terminal device 10B and switch the mobile terminal device. Further, when the mobile terminal device 10A is switched, continuation information necessary for continuation of processing is automatically acquired and inherited by the mobile terminal device 10B after the switching, so that the operation at the time of switching is prevented from becoming complicated. In addition, the time required for switching can be shortened.

  In particular, before the battery of the mobile terminal device 10A runs out, or when the connection between the in-vehicle device 50 and the mobile terminal device 10A is disconnected, or between the mobile terminal device 10A and the map distribution server 90. When wireless communication using radio waves is interrupted due to a decrease in radio wave intensity, it is possible to switch to the mobile terminal device 10B and continue the same or similar processing.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, each of FIGS. 3 to 5 is used to separately explain the switching operation of the mobile terminal device when the battery is dead, the connection is cut, or the radio field strength is lowered. Is called.

  Moreover, although embodiment mentioned above demonstrated the case where two portable terminal devices 10A and 10B were connected, even if it is a case where three or more portable terminal devices are connected, this invention can be applied. it can. If there are a plurality of portable terminal devices to be switched to, a selection screen of the portable terminal device is displayed before switching (for example, the selection screen is created by the processing continuation instruction unit 80 and the display processing unit 86 The user may select the portable terminal device to be switched to by operating the operation unit 54.

  Further, in addition to the case where both portable terminal devices 10A and 10B to be switched are connected to the in-vehicle device 50 in advance, only the portable terminal device 10A is initially connected and switching is required. It is conceivable that the mobile terminal device 10B is connected to the mobile terminal device 10B.

  In the above-described embodiment, the processing is continued by switching the mobile terminal device for the map display or the like performed by executing the map application. However, the processing to be continued is the map performed by executing the map application. It may be other than display.

  For example, a case where music playback software is executed in the mobile terminal devices 10A and 10B to perform music playback processing can be considered. Specifically, when playing multiple songs in an artist's album in order, the battery may run out and the process may be interrupted. Processing can continue. In this case, information indicating the artist name, album name, music name being played back, and the like is acquired as continuation information and stored in the continuation information storage unit 58.

  As another example, a case where software for a social network system is executed in the mobile terminal devices 10A and 10B can be considered. Specifically, during this process, when a password is entered and information is exchanged, the battery may run out and the process may be interrupted, and the process may be continued as in the case of a map display or the like. it can. In this case, login information such as a password is acquired as continuation information and stored in the continuation information storage unit 58.

  As described above, according to the present invention, it is difficult to obtain a processing result corresponding to a process being executed in the mobile terminal device 10A, that is, when the use of the mobile terminal device is disabled or disabled. Before becoming, it becomes possible to continue the process in another mobile terminal device 10B and switch the mobile terminal device.
