Correspond.

  The in-vehicle device 1 according to the present embodiment has such a configuration. Next, an operation for preventing forgetting to bring the mobile terminal device 90 into the vehicle will be described.

  FIG. 2 is a diagram illustrating a specific example in which the detection results of the mobile terminal device 90 are tabulated. In the present embodiment, when one or a plurality of mobile terminal devices 90 are detected by the mobile terminal detection unit 53, the detection result totaling unit 54 totals the pattern frequencies for each combination pattern of the detected mobile terminal devices 90. . In the example shown in FIG. 2, F1 and F2 indicate two portable terminal devices 90 carried by the user who drives the vehicle best, and M is carried by a user who often rides with the user. A mobile terminal device 90 is shown. In the in-vehicle device 1, since it is not known who carries the detected mobile terminal device 90, it is not known that one user is actually carrying the mobile terminal device 90 corresponding to F <b> 1 and F <b> 2. .

  In the counting result shown in FIG. 2, the frequency (pattern frequency) of pattern 3 in which only F1 and F2 are detected is the highest, and the number of times is 200. Further, the frequency of the pattern 4 in which only F1 and M are detected is the next highest, and the number of times is 100 times.

  FIG. 3 is a flowchart showing an operation procedure for determining whether the mobile terminal device 90 is forgotten to be brought into the vehicle by the in-vehicle device 1.

  When a passenger such as a driver gets into the vehicle and the key switch is operated and the in-vehicle device 1 starts to operate, the mobile terminal detection unit 53 starts detecting the mobile terminal device 90 within the communicable range by Bluetooth. (Step 100), it is determined whether there is a detected portable terminal device 90 (Step 102). If at least one mobile terminal device 90 is detected, a positive determination is made.

  Next, the forget-to-carry determination unit 55 extracts a pattern having the highest frequency among the patterns including the detected mobile terminal device 90 (step 104), and the undetected mobile terminal this time among the extracted patterns It is determined whether or not the device 90 is included, that is, whether or not there is a portable terminal device 90 that has been forgotten to be brought in (step 106). If there is a mobile terminal device 90 that has been forgotten to be brought in, an affirmative determination is made, and the forget-to-carry-in notification unit 56 specifies the mobile terminal device 90 and gives notification indicating that forgetting to bring in has occurred (step 108). ). This notification is preferably performed using both display and sound, but only one of them may be performed. The identification of the mobile terminal device 90 is, for example, clearly indicating the identification information of the device, but by adding a name that can identify the user who carries each mobile terminal device 90 at the time of pairing, The name can also be used for notification of forgetting to bring it in.

  If there is no portable terminal device 90 forgotten to bring in, a negative determination is made in the determination of step 106. In this case, no notification indicating that forgetting to bring in has occurred.

  If there is no detected mobile terminal device 90, a negative determination is made in the determination in step 102. In this case, the forget-to-carry determination unit 55 extracts the most frequently used pattern (step 110), and the forget-to-carry-in notification unit 56 specifies all the mobile terminal devices 90 included in this pattern and forgets to bring in A notification indicating the occurrence is made (step 112).

  After the notification in steps 108 and 112 is completed, or when there is no portable terminal device 90 to be notified, a negative determination is made in the determination in step 106, and then the detection result totaling unit 54 performs the detection operation in step 100. The detection pattern is updated by reflecting the result detected this time (step 114).

  For example, a description will be given using the example shown in FIG. It is assumed that only the mobile terminal device 90 indicated by F1 is detected this time. There are three patterns 3 to 5 including F1, and pattern 3 has the highest frequency among them. Therefore, when paying attention to the pattern 3, since F2 is included in addition to F1, it is notified that forgetting to bring in the portable terminal device 90 corresponding to F2 has occurred.

  Note that when two portable terminal devices 90 indicated by F1 and F2 are detected this time, the most frequently used pattern 3 including these two does not include other portable terminal devices 90. No notifications will be made. In addition, if no mobile terminal device 90 is detected this time, notification that forgetting to bring in two mobile terminal devices 90 corresponding to F1 and F2 included in the pattern 3 having the highest frequency has occurred. Is done.

  By the way, in the description of the embodiment described above, the pattern with the highest frequency is extracted. However, when this frequency is low (the number of times of patterning is small), it is considered that it is impossible to accurately determine forgetting to bring in. Therefore, when the frequency is low, the notification in this embodiment may not be performed.

  FIG. 4 is a flowchart showing a modification in which the notification when the pattern frequency is low is omitted. The flowchart shown in FIG. 4 is different from the flowchart shown in FIG. 3 in that step 107 is added after step 106 and step 111 is added after step 110. Hereinafter, the description will be given focusing on these added steps 107 and 111.

  If there is a mobile terminal device 90 that has been forgotten to be brought in and an affirmative determination is made in the determination in step 106, the forget-to-carry determination unit 55 determines whether the pattern frequency (number of patterns) extracted in step 104 is greater than or equal to a predetermined value. Is determined (step 107). If the value is equal to or greater than the predetermined value, an affirmative determination is made, and the process proceeds to step 108 for notification. On the other hand, if it is less than the predetermined value, a negative determination is made in the determination of step 107. In this case, the notification in step 108 is omitted.

  In addition, after there is no detected mobile terminal device 90 and a pattern having the highest frequency is extracted in step 110, the forget-to-take-in determination unit 55 determines whether the frequency (number of patterns) of the extracted pattern is equal to or greater than a predetermined value. It is determined whether or not (step 111). If the value is equal to or greater than the predetermined value, an affirmative determination is made, and the process proceeds to step 112 to be notified. On the other hand, if it is less than the predetermined value, a negative determination is made in the determination of step 111. In this case, the notification in step 112 is omitted.

  Thus, in the in-vehicle device 1 of the present embodiment, the mobile terminal device 90 that has been brought into the vehicle in the past is detected and totaled, and whether or not the mobile terminal device 90 has been forgotten to be brought in is determined based on the total result. Accordingly, it is possible to prevent forgetting to bring the portable terminal device 90 into the vehicle in accordance with the actual situation of use for a plurality of users as well as the portable terminal device 90 carried by a specific user.

  Further, by detecting a combination pattern of portable terminal devices 90 that are brought in and using it for the determination, it is possible to efficiently determine whether the mobile terminal device 90 that is likely to be brought into the vehicle at the same time is forgotten.

  Further, based on the combination pattern of the mobile terminal devices 90 having the highest detection frequency, it is determined whether or not the mobile terminal device 90 is forgotten to be brought in. Specifically, when a plurality of mobile terminal devices 90 are included in the pattern to be determined, a part of the mobile terminal device 90 detected when a passenger gets into the vehicle is included. At some point, the remaining mobile terminal device 90 determines and notifies that it has been forgotten. Thereby, it is possible to prevent forgetting to bring in the portable terminal device 90 that is particularly frequently brought into the vehicle.

  In addition, by performing notification when the detection frequency exceeds a predetermined value, it is possible to improve the determination accuracy of forgetting to bring the mobile terminal device 90.

  In addition, the mobile terminal device 90 connected by the Bluetooth method is a target of forgetting to bring in and notification. If it is the portable terminal device 90 of the Bluetooth system, the portable terminal device 90 within the communication range after pairing can be connected without performing any special work, and it is possible to automatically determine whether to bring it in.

  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, the decision to forget to bring in is performed by paying attention to the pattern having the highest frequency. However, one or a plurality of patterns having the highest frequency is set as the “pattern upper group”, and the pattern upper group is focused on. You may make it perform a forgetting determination.

  FIG. 5 is a flowchart showing a modification in which the forgetting to bring in determination is performed by paying attention to the pattern upper group. The flowchart shown in FIG. 5 differs from the flowchart shown in FIG. 3 in that step 104 is replaced with step 104A, step 106 is replaced with step 106A, step 110 is replaced with step 110A, and step 112 is replaced with step 112A. Yes. In the following, description will be given focusing on these replaced steps.

  After at least one mobile terminal device 90 is detected and an affirmative determination is made in the determination in step 102, the carry-in forget determination unit 55 extracts a pattern upper group including the detected mobile terminal device 90 (step 104A). ), It is determined whether or not the extracted pattern upper group includes the mobile terminal device 90 that has not been detected this time, that is, whether or not there is a mobile terminal device 90 that has been forgotten to be brought in (step 106A). If there is an undetected mobile terminal device 90, a notification of forgetting to carry in is specified (step 108).

  Note that the pattern upper group includes, for example, up to the second pattern in descending order of pattern frequency, or includes a pattern having the highest frequency and a pattern having a frequency of 50% or more with respect to the frequency (number of patterns). Cases can be considered. The undetected mobile terminal device 90 included in the pattern upper group means “undetected mobile terminal device 90 among the plurality of mobile terminal devices 90 included in the plurality of patterns constituting the pattern upper group”. It is.

  In addition, when there is no detected mobile terminal device 90 and a negative determination is made in the determination in step 102, the forget-to-take-in determination unit 55 extracts a pattern upper group including the most frequently used pattern. (Step 110A), the forget-not-for-notification unit 56 specifies all the mobile terminal devices 90 included in the upper pattern group and gives notification indicating that forget-in-forget has occurred (Step 112A). In this way, it may be determined and notified of forgetting to bring in the upper pattern group.

  In the above-described embodiment, the portable terminal device 90 is considered as a target for forgetting to bring in, but forgetting to bring in and notifying other portable devices such as audio players and other wearable terminals attached to human bodies. You may make it perform.

  Further, in the above-described embodiment, the mobile device connected by Bluetooth as a wireless method is targeted. However, the present invention is applied to a wireless device other than Bluetooth, for example, a mobile device connected by wireless LAN. Also good.

  As described above, according to the present invention, a specific user can be obtained by detecting and counting portable devices that have been brought into the vehicle in the past and determining whether or not the portable device has been forgotten to be brought in based on the counting results. Can prevent the user from forgetting to bring a mobile device into the car according to the actual situation of use for multiple users as well as mobile devices
