[Vehicle information presentation processing of vehicle information presentation system]
Next, in the vehicle information presentation system configured as described above, a vehicle state presentation process executed by the control of the vehicle processing device 11 will be described with reference to the flowcharts of FIGS. 3 and 4.

  First, in the vehicle information presentation system, the mobile terminal 50 to be connected is registered in the vehicle information communication apparatus 10 in order to perform wireless communication in conformity with the Bluetooth standard between the vehicle information communication apparatus 10 and the mobile terminal 50. Processing is required. Therefore, in the vehicle information presentation system, as shown in FIG. 3, the engine key is inserted into the key cylinder and the engine switch is turned on (the vehicle can be started without inserting the engine key into the key cylinder). When the immobilizer system is mounted like an electronic key that can be used, immobilizer ID authentication is established between the electronic key and the system), and in step S1, the operation input unit 15 in the vehicle information communication device 10 The mobile terminal 50 that the user wants to connect to is registered in the vehicle information communication apparatus 10 via the.

  In response to this, the vehicle information communication device 10 stores setting information indicating the registered information of the mobile terminal 50 in the EEPROM 12 or the like. Here, for convenience of explanation, it is assumed that one mobile terminal 50 is registered. However, a plurality of mobile devices may be registered. In the vehicle information presentation system, when such a registration operation is completed, the vehicle state can be notified to the user via the mobile terminal 50.

  Then, in the next step S2, the vehicle processing apparatus 11 turns off the engine switch based on the engine switch state information detected by the engine switch state detection unit 29 and removes the engine key from the key cylinder. It is determined whether or not it has been removed.

  Here, when the vehicle processing device 11 determines that the engine switch is turned off and the engine key is not removed from the key cylinder, the vehicle processing device 11 determines that the user is still in the vehicle. Then, the processing of step S2 is repeated (in the case of an electronic key that can start the vehicle without inserting an engine key into the key cylinder, the off state of the engine switch can usually be detected. Since the insertion / extraction of the key cannot be determined, it is determined that the key has been removed according to the operation condition of the door locking of the electronic key.

  On the other hand, when it is determined that the engine switch is turned off and the engine key is removed from the key cylinder, the vehicle processing device 11 proceeds to step S3. Then, in step S3, the vehicle processing device 11 determines whether or not the vehicle door has been closed after being opened once, based on the door open / close state information detected by the door open / close state detection unit 28. Based on the door lock state information detected by the door lock state detector 20, it is determined whether or not the closed vehicle door is locked.

  Here, the vehicle processing device 11 determines that the user is still in the vehicle when it is determined that the vehicle door is once opened and then closed and the vehicle door is not locked. Then, the processing from step S2 is repeated.

  On the other hand, if the vehicle processing device 11 determines that the vehicle door is once opened and then closed and the vehicle door is locked, the vehicle processing device 11 determines that the user has exited the vehicle. That is, in the vehicle processing device 11, the engine switch is turned off, the engine key is removed from the key cylinder, the vehicle door is once opened, then closed, and the closed vehicle door is locked. It is detected on the condition that the user got out of the vehicle.

  Here, the vehicle information communication device 10 including the vehicle processing device 11 does not stop at the same time even when the engine switch is turned off, but at least after the engine switch is turned off. It can be operated for several minutes. As a result, the vehicle information communication apparatus 10 can collect vehicle information even after the engine switch is turned off.

  When the vehicle processing device 11 detects that the user has exited the vehicle in this manner, wireless communication is established between the vehicle Bluetooth processing unit 16 and the mobile Bluetooth processing unit 52 in step S4. Thus, it is determined whether or not a link is established with the mobile terminal 50, that is, whether or not the mobile terminal 50 is in a wireless connection state.

  Here, when it is determined that the vehicle processing device 11 is in a state where the link with the mobile terminal 50 is not established (unconnected state), the vehicle processing device 11 determines that communication is not possible and detects vehicle information. A series of processing is ended without turning off the system.

  The communication range between the vehicle information communication apparatus 10 and the mobile terminal 50 is 5m to 100m in line-of-sight distance according to class 1 to class 3 in the Bluetooth standard. Specifically, the communication range of class 1 is about 100 m, the communication range of class 2 is 20 m to 30 m, and the communication range of class 3 is 5 m to 10 m. Therefore, the state where the link between the vehicle information communication device 10 and the mobile terminal 50 is not established means that the user who gets off the vehicle moves to a region beyond the communication range while holding the mobile terminal 50. It means that

  On the other hand, if it is determined that the link is established with the mobile terminal 50, the vehicle processing device 11 collects various vehicle information detected by the detection units 20 to 27 in step S5. And temporarily stored in the RAM 13.

  And the processing apparatus 11 for vehicles controls the Bluetooth process part 16 for vehicles so that vehicle information may be transferred to the mobile terminal 50 registered in step S1 in step S6. At this time, the vehicle processing apparatus 11 may transfer all the vehicle information detected by the detection units 20 to 27, or may select and transfer only the vehicle information determined to be not normal. It may be.

  Note that the vehicle processing apparatus 11 transfers vehicle information to each of the mobile devices 50 when there are a plurality of registered mobile devices 50. Here, in the vehicle information presentation system, vehicle information is transferred via wireless communication conforming to the Bluetooth standard, so that no charge is charged unlike when a normal telephone line is used.

  In the vehicle information presentation system, the time when the vehicle information is transferred in step S6 is set as the first time. In response to this, the mobile terminal 50 receives the transferred vehicle information via the terminal antenna 51 and the mobile Bluetooth processing unit 52, and the received vehicle information is stored in the storage unit 54 by the mobile processing device 53. To remember.

  Subsequently, in step S <b> 7, the vehicle processing device 11 determines whether or not the wireless connection with the mobile terminal 50 has been disconnected by monitoring the communication state of the vehicle Bluetooth processing unit 16. Here, if the vehicle processing apparatus 11 determines that the wireless connection with the mobile terminal 50 is in a disconnected state, the vehicle processing apparatus 11 determines that communication is not possible, and sets a series of processing as system off. Exit.

  On the other hand, if the vehicle processing apparatus 11 determines that the wireless connection is established with the mobile terminal 50, the processing proceeds to step S8 in FIG. And the processing apparatus 11 for vehicles determines whether the vehicle door was unlocked based on the door lock state information detected by the door lock state detection part 20 in step S8.

  Here, if it is determined that the vehicle door is not unlocked, the vehicle processing device 11 determines that the user has not yet boarded the vehicle, and repeats the process of step S8.

  On the other hand, when it is determined that the vehicle door is unlocked, the vehicle processing device 11 determines that the user has boarded the vehicle, and in step S9, various vehicle information detected by the detection units 20 to 27. Are stored in the RAM 13 or the like.

  And the processing apparatus 11 for vehicles transfers the various vehicle information except the door lock state information which shows that the vehicle door was unlocked to the mobile terminal 50 in step S10. At this time, the vehicle processing device 11 may transfer all the vehicle information. In step S6, when only the abnormal vehicle information is selected and transferred, only the transferred vehicle information is displayed. You may make it newly select and transfer.

  Note that the time when the vehicle information is transferred in step S10 is the second time. In response to this, the mobile terminal 50 receives the transferred vehicle information via a terminal antenna 51 and a mobile Bluetooth processing unit 52 (not shown), and receives the received vehicle information via the mobile processing device 53. And stored in the storage unit 54.

  In step S11, the mobile terminal 50 was transferred at the second time in step S10 and the vehicle information transferred at the first time in step S6 by the mobile processing unit 53 as the comparison means. The vehicle information is read from the storage unit 54 and compared, and notification information based on the comparison result is created and displayed on the display unit 55 in step S12.

  Specifically, the moving body processing device 53 determines that all vehicle information is the same as a result of comparison of vehicle information transferred twice, that is, if all vehicle information is normal. For example, as shown in FIG. 5, information indicating the type of vehicle information, vehicle information at the first time (step S6), and notification information that associates the vehicle information at the second time (step S10) are created, Displayed on the display unit 55. Here, the moving body processing device 53 displays “◯” or “O” as a display indicating whether or not each vehicle information is normal as the vehicle information at the first time (step S6) and the vehicle information at the second time (step S10). “×” is displayed.

  In addition, the moving body processing device 53 has a case in which some vehicle information is different between the vehicle information at the first time (step S6) and the vehicle information at the second time (step S10), that is, If there is an abnormality in the vehicle information of the part, notification information as shown in FIG. 6 is created and displayed on the display unit 55.

  Further, as shown in FIG. 7, for example, the moving body processing device 53 notifies only about the vehicle information that is different as a result of the comparison of the vehicle information transferred twice, that is, the vehicle information that is abnormal. Information may be created and displayed on the display unit 55. In addition, when the vehicle information with abnormality is detected, the moving body processing device 53 may output a predetermined voice message by a sound emitting mechanism (not shown) as well as a display.

  In step S13, the vehicle processing apparatus 11 determines whether or not the engine key is inserted into the key cylinder and the engine switch is turned on based on the engine switch state information detected by the engine switch state detection unit 29. Determine.

  Here, when the vehicle processing device 11 determines that the engine switch is not turned on, the vehicle information communication device 10 repeats the processing from step S6 in FIG. 3 while the engine switch is turned on. If it is determined by the vehicle processing device 11 that it is determined that the user has returned to the vehicle, the vehicle information does not need to remain in the mobile terminal 50, so step S14. In FIG. 3, an erasure signal for erasing the vehicle information transferred to the mobile terminal 50 is transmitted to the mobile terminal 50, and the processing from step S2 in FIG. 3 is repeated.

  In the vehicle information presentation system, by executing such a series of processes, various vehicle information detected by the vehicle information communication device 10 can be transferred to the mobile terminal 50 to notify the user of the vehicle state. it can.

  Note that the vehicle information communication device 10 normally only has to collect vehicle information once in step S5 in FIG. 3 or step S9 in FIG. 4, but if it is a period in which it can operate after detecting various vehicle information, For example, the vehicle information may be updated every 100 ms. In this case, the transfer of the vehicle information is continued until the link with the mobile terminal 50 is broken.

  At this time, the vehicle information communication apparatus 10 stores the update time and transfer time of such vehicle information in the EEPROM 12 or the like as setting information. That is, since the vehicle information communication apparatus 10 normally collects vehicle information only once when the condition is satisfied, both the update setting and the transfer setting may be performed once, but every predetermined cycle time. When the vehicle information is updated and transferred, the update setting and transfer setting for realizing this content are performed. The update setting here is to set the cycle time for updating the vehicle information to be collected, and the transfer setting is the time to transfer the vehicle information to the mobile terminal 50 and until the link is broken. Is to set information such as whether or not to continue.

  In addition, as shown in FIGS. 5 to 7, the mobile terminal 50 only displays notification information based on the comparison result of the vehicle information transferred at the first time and the second time on the display screen. For example, as shown in FIG. 8, a list of all transferred vehicle information is displayed on the display screen as notification information, or as shown in FIG. 9, a list of vehicle information with an abnormality is displayed as notification information. Or may be displayed. The mobile terminal 50 may output a predetermined voice message in response to an operation of a predetermined switch (not shown).

[Effect of the embodiment]
