  FIG. 3 is a flowchart showing the vehicle control method according to the embodiment of the present invention.

  First, as advance preparation, in the communication terminal 10, the same information as the device specifying information 24A of the controller 20 is stored in the storage unit 14 as the registered device information 14B (S101). In addition to S101, the controller 20 causes the storage unit 24 to store the same information as the terminal identification information 14A of the communication terminal 10 as the registered terminal information 24C (S102). If S101 and S102 are executed only once when the vehicle control method according to this embodiment is executed for the first time, they can be omitted in the second and subsequent executions.

  After executing S101 and S102 as advance preparations, the vehicle occupant causes the communication terminal 10 to approach the door of the vehicle, whereby the terminal identification information 14A for identifying the communication terminal 10 and the control signal for unlocking the door Is transmitted from the communication terminal 10 to the controller 20 (operated device) (S103).

  After receiving the terminal identification information 14A from the communication terminal 10, the controller 23 of the controller 20 determines whether or not the received terminal identification information 14A matches the registered terminal information 24C stored in the storage unit 24 (S104). ).

  When it is determined that the received terminal identification information 14A does not match the stored registered terminal information 24C (No in S104), the control unit 23 of the controller 20 transmits error information via the first communication unit 21 to the communication terminal. 10 (S105), and the process is terminated.

  On the other hand, when it is determined that the received terminal identification information 14A matches the stored registered terminal information 24C (Yes in S104), the control unit 23 of the controller 20 unlocks the door via the external input / output unit 25. An unlock signal for locking is transmitted to the door lock control device 40 (S106). As a result, the controller 20 that is the operated device is controlled by the terminal identification information 14A transmitted by the communication terminal 10 (terminal information transmission step).

  After receiving the unlock signal from the controller 20, the door lock control device 40 unlocks the door (S107), and transmits an unlock completion signal to the controller 20 to notify the completion of the unlock (S108). ).

  After receiving the unlock completion signal, the control unit 23 of the controller 20 transmits the device identification information 24A stored in the storage unit 24 to the second communication unit 12 of the communication terminal 10 via the second communication unit 22. (S109). Thereby, the device specifying information 24A for specifying the controller 20 is transmitted from the controller 20 to the communication terminal 10 in response to the transmission of the terminal specifying information 14A from the communication terminal 10 (device specifying information transmitting step).

  After receiving the device specifying information 24A from the controller 20 (device specifying information receiving step), the communication terminal 10 determines whether or not the received device specifying information 24A matches the registered device information 14B stored in the storage unit 14. (S110).

  When it is determined that the received device identification information 24A does not match the stored registered device information 14B (No in S110), the control unit 13 of the communication terminal 10 ends the process without controlling the module activation state. .

  On the other hand, when the control unit 13 of the communication terminal 10 determines that the received device specifying information 24A matches the stored registered device information 14B (Yes in S110), the activation state of the module corresponding to the device specifying information 24A Is controlled (S111). Specifically, the activation state of the module for performing billing processing and the module for performing hands-free communication in the automatic fee collection system (ETC) is controlled to be usable. Thus, when the communication terminal 10 receives the same device specifying information 24A as the registered device information 14B, which is predetermined device specifying information, the activation state of the module corresponding to the device specifying information 24A is controlled (module control). Step).

  When a state in which communication with the controller 20 cannot be performed after controlling the activation state of the module continues for a predetermined time (Yes in S112), the module in the activation state is set to the stop state using the timer of the control unit 13. (S113). When the state in which communication with the controller 20 is possible continues (in the case of No in S112), the startup state of the module is maintained by repeating S112. Note that the user of the mobile terminal 10 (vehicle occupant) may manually stop the module regardless of the determination in S112.

  Through the processing as described above, the vehicle control method according to the embodiment of the present invention uses the communication terminal 10 to control the controller 20 that is an operated device mounted on the vehicle, and receives the communication terminal 10 from the controller 20. The activation state of the module corresponding to the device specifying information 24A can be controlled.

  The process for stopping the module after a predetermined period of time during which communication with the controller 20 is not possible is the first time 5 seconds, the second time 30 seconds, the third time 60 seconds, and so on. It may be performed after trying to establish a communication connection with the controller 20 in such a manner as to spread.

  Further, the processing for bringing the module into the stop state in this way may be performed on the module for performing hands-free communication.

  Next, with reference to FIG. 4, the charging process of the automatic fee collection system (ETC) in the communication terminal according to the embodiment of the present invention will be described.

  First, on a toll road such as an expressway, the communication terminal 10 carried by a vehicle occupant receives a signal for starting a charging process from the ETC roadside wireless device at the toll gate (S201). After receiving the signal from the ETC roadside wireless device, the communication terminal 10 transmits the vehicle type information stored in the storage unit 14 to the ETC roadside wireless device (S202). Thereafter, the communication terminal 10 receives the charge information transmitted from the ETC roadside wireless device according to the transmitted vehicle type information (S203), and stores it in the storage unit 14 (S204). After that, the settlement processing is executed by subtracting the stored fee information from the electronic money stored in advance (S205). In addition, when the communication terminal 10 has a function as a credit card, the payment process may be executed by the same process as the credit card.

  Communication between the communication terminal 10 and the ETC roadside radio apparatus in the processing of S203 to S204 described above is performed via the ETC radio unit 15, whereby the communication terminal 10 performs billing processing with the ETC roadside radio apparatus. It can be carried out.

With this configuration, when the controller 20 is mounted on a vehicle, information necessary for ETC is handled between the communication terminal 10 and the vehicle using the terminal identification information 14A and the device identification information 24A. Can be linked together. Therefore, even when the same vehicle is shared by a plurality of users, it is possible to charge a fee separately for each user.

  Furthermore, the device identification information 24A includes vehicle type information 24B related to the vehicle type of the vehicle, and the control unit 13 of the communication terminal 10 may be configured to control the module using the vehicle type information. With this configuration, even when ETC is used in a plurality of vehicles using one communication terminal 10, the communication terminal 10 can charge according to the vehicle type.

  Further, the control unit 13 may be configured to place the module in a stopped state after a state in which communication with the controller 20 is not possible continues for a predetermined time. With this configuration, when a state in which the communication terminal 10 and the controller 20 cannot operate in cooperation continues, the module can be brought into an end state in the communication terminal 10 without the passenger being particularly aware of it. it can. Therefore, even when the door lock is temporarily released, for example, when loading and unloading luggage, wasteful power consumption by the module can be suppressed when leaving the vehicle without running the vehicle.

  Further, the module of the communication terminal 10 may be configured as a module for performing hands-free communication. By configuring in this way, for example, after the user sends the terminal identification information 14A to the controller 20 for releasing the vehicle door lock, communication by hands-free is automatically started without performing any special operation. be able to.

  Note that the vehicle control system 1 and the vehicle control method according to the embodiment of the present invention have technical features corresponding to the communication terminal 10 and have the same functions and effects.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  For example, the registration device information 14B stored in the storage unit 14 of the communication terminal 10 may be stored in the storage unit 14 by omitting the vehicle type information. In this case, even if the vehicle type information 24B is included in the device identification information 24A transmitted from the controller 20, the identity between the device identification information 24A and the registered device information 14B is determined using a portion other than the vehicle type information 24B. As a result, the process of S111 in the vehicle control writing method described above is performed.

  In the present embodiment, the communication with the ETC roadside wireless device is configured to be performed by the ETC wireless unit 15 of the communication terminal 10, but the communication is connected to the external input / output unit 25 via electric wiring. You may make it carry out using the ETC vehicle-mounted apparatus. In this case, the ETC in-vehicle device is configured as a device that performs necessary processing on the vehicle side with respect to ETC, such as a transmission / reception device with the ETC roadside wireless device provided on the road, a display device that displays the processing result of ETC, and the like Is provided. Information necessary for ETC charging processing (for example, transmission / reception of vehicle type information) is mainly performed between the ETC in-vehicle device and the ETC roadside wireless device, and at least information related to the charging result (that is, fee information) is stored in the controller. It can be configured to be transmitted from the 20 second communication units to the second communication unit 12 of the communication terminal 10.
