Reference numeral 24 is a memory for storing vehicle identification information unique to the vehicle-mounted device 2.

  Next, with reference to FIG. 1, the operation of the automatic locking device including the in-vehicle device 2 and the electronic key 18 will be briefly described. The RF circuit 22 of the in-vehicle device 2 transmits an inquiry signal for the electronic key within a predetermined range (for example, a radius of 1.5 m). The electronic key 18 stores therein vehicle identification information capable of uniquely identifying a vehicle. When an inquiry signal is received from the RF circuit 22 of the in-vehicle device 2, an internal vehicle identification is performed as a response to the inquiry signal. Send information. The RF circuit 22 receives the vehicle identification information transmitted by the electronic key 18 and outputs it to the control unit 21. The control unit 21 collates the vehicle identification information held in advance in the memory 24 with the vehicle identification information received by the RF circuit 22, and if the two match completely, unlocks the door lock to the door lock actuator 23. Output instructions to lock. In response to this, the door lock actuator 23 unlocks the door lock. The control unit 21 controls the door lock actuator 23 so that the unlocked state of the door lock continues while the vehicle identification information received by the RF circuit 22 matches the internal vehicle identification information.

  On the other hand, when the response signal is not received even though the RF circuit 22 has transmitted the inquiry signal, the control unit 21 cannot continue to receive the response vehicle identification information for a predetermined time (for example, 5 If the duration of the state in which the vehicle identification information cannot be received exceeds a predetermined time, an instruction to lock the door lock is output to the door lock actuator 23. In response to this, the door lock actuator 23 locks the door lock. While the vehicle identification information that is a response to the inquiry signal cannot be received by the RF circuit 22 and when the vehicle identification information that does not match the vehicle identification information stored in the memory 24 is received, The door lock actuator 23 is controlled so that the locked state of the lock continues.

  In this way, the control unit 21 performs control so that the door lock is unlocked when the electronic key 18 approaches the predetermined range of the automobile, and the door lock is locked when the electronic key 18 moves away from the predetermined range. Thus, the driver can lock / unlock the door only by carrying the electronic key 18.

  Next, with reference to FIG. 2, a setting operation for controlling the automatic lock device by remote operation from an external telephone will be described. First, when the mobile phone 1 is in a normal standby state (step S1), when the user of the mobile phone 1 operates the operation unit 12 to select a menu for setting the remote auto-lock function (step S2), the CPU 11 Reads the remote auto-lock setting application program from the memory 15 and activates the remote auto-lock setting application (step S3).

  Next, conditions are set when the automatic lock device is controlled by remote control. The condition set here is that if the number of incoming calls from the same designated telephone number within the designated time matches the designated number of incoming calls at the time of locking or unlocking, the CPU 11 sets the condition for locking or unlocking. It is for judging that it was satisfied. First, when the remote auto-lock setting application is activated, a message for instructing input of the designated telephone number is displayed on the display unit 13. Here, the user operates the operation unit 12 to input a designated telephone number that is a telephone number of a telephone (source) that performs remote operation. When a public telephone is used as a caller, a public telephone menu is selected instead of inputting a telephone number. In response to this, the CPU 11 registers the designated telephone number by storing the inputted designated telephone number in the memory 15 (step S4). When a public telephone is selected, information indicating that it is a public telephone is registered.

  Next, a message instructing the input of the specified time is displayed on the display unit 13. Here, the user operates the operation unit 12 to input a specified time (for example, 5 minutes). In response to this, the CPU 11 sets the designated time by storing the input designated time value in the memory 15 (step S5).

  Next, a message instructing the input of the designated number of incoming calls at the time of locking is displayed on the display unit 13. Here, the user operates the operation unit 12 to input the designated number of incoming calls (for example, 3 times) at the time of locking. In response to this, the CPU 11 sets the designated number of incoming calls at the time of locking by storing the value of the designated number of incoming calls in the memory 15 (step S6).

  Next, when the user of the mobile phone 1 operates the operation unit 12 to select a menu for setting to release the remote auto-lock function (step S7), the display unit 13 is instructed to input the designated number of incoming calls at the time of unlocking. Display a message. Here, the user operates the operation unit 12 to input the designated number of incoming calls (for example, 5 times) at the time of unlocking so that the designated number of incoming calls at the time of unlocking> the designated number of incoming calls at the time of locking. In response to this, the CPU 11 stores the input designated incoming call count value in the memory 15 to set the designated incoming call count at the time of unlocking (step S8). By making the specified number of incoming calls when unlocking larger than the value of the specified number of incoming calls when locking, it is possible to prevent unlocking even if there are as many missed calls as the specified number of incoming calls when locking Can do.

  With this operation, whether or not the specified telephone number (or information indicating that it is a public telephone), the specified time, the specified number of incoming calls at the time of locking and unlocking, and the remote auto-lock function are activated in the memory 15 Information for identifying whether or not is registered.

  Next, with reference to FIG. 3, the operation of the mobile phone 1 when the door lock actuator 23 is controlled and locked by remote control from the telephone 5 will be described. First, the user makes a telephone call to the mobile phone 1 that is registered in the designated phone number or dials the phone number of the mobile phone 1 from the telephone 5 of the public telephone, and is placed in the car. In the normal standby state (step S11), the CPU 11 determines whether there is an incoming call depending on whether there is an incoming call notification from the wireless communication unit 14 (step S12). If there is an incoming call as a result of this determination, the CPU 11 monitors the state of the operation unit 12 and determines whether an incoming call response operation has been performed (step S13). If there is an incoming call response, the CPU 11 switches to the call mode and makes a voice call until the call is disconnected (steps S14 and S15). On the other hand, when there is an incoming call but no incoming call response operation is performed, the CPU 11 executes a missed call process (step S16). Then, the CPU 11 specifies the caller telephone number of the incoming call, and determines whether or not the specified caller telephone number matches the designated telephone number stored in the memory 15 (step S17). When the caller telephone number is not the designated telephone number, the CPU 11 ends the process after executing the missed call process and enters a normal standby state.

  Next, when the caller telephone number is the designated telephone number, the CPU 11 counts the number of incoming calls from the designated telephone number and starts a timer for measuring the elapsed time. Then, the CPU 11 determines whether or not the remote auto-lock function has been set (step S18). If not, the CPU 11 ends the process after executing the missed call process and enters a normal standby state. On the other hand, if the remote auto-lock function has been set, the CPU 11 acquires the elapsed time from the first incoming call from the designated telephone number from the timer, and designates the elapsed time and the designation stored in the memory 15. The time is compared to determine whether or not the elapsed time is within the specified time (step S19). If the elapsed time exceeds the specified time, the missed call process is executed and the process ends and the normal standby state It becomes.

  Next, if the elapsed time is within the designated time, the CPU 11 determines whether or not the count value of the number of incoming calls from the designated telephone number matches the designated number of incoming calls at the time of locking stored in the memory 15 ( In step S20), if they do not match, the missed call process is executed and then the process is terminated to enter a normal standby state. On the other hand, when the number of incoming calls from the designated telephone number matches the designated number of incoming calls at the time of locking stored in the memory 15, that is, the number of incoming calls from the same designated telephone number within the specified time is the number of incoming calls. If it matches the designated number of incoming calls, the CPU 11 determines that the condition for locking is satisfied. If the condition to be locked is satisfied, the CPU 11 reads out the voice data of the voice guidance stored in the memory 15 in advance and sends this voice data to the telephone 5 via the wireless communication unit 14 (step). S21). This voice guidance notifies the calling party of the caller that the operation unit 12 of the mobile phone 1 is locked and the electronic key 18 is disabled.

  Next, the CPU 11 locks the operation unit 12 to invalidate it (step S22), and instructs the power supply control unit 20 to stop power supply. In response to this, the power supply control unit 20 stops the supply of power supplied from the battery 19 to the electronic key 18 (step S23). As a result, the electronic key 18 does not respond to the inquiry signal from the RF circuit 22, so the control unit 21 regards the electronic key 18 as moving away from the predetermined range and locks the door lock actuator 23. The instruction to do is output. In response to this, the door lock actuator 23 locks the door of the automobile.

  Next, the CPU 11 reads out voice guidance voice data stored in the memory 15 in advance, and sends this voice data to the telephone 5 via the wireless communication unit 14 (step S24). This voice guidance notifies the calling party of the caller that the door is locked by disabling the electronic key 18.

  Therefore, even when the user forgets to place the mobile phone 1 having the electronic key 18 in the automobile, the electronic key 18 can be disabled by making a call from the telephone 5 to the mobile phone 1. Therefore, the automatic locking device of the automobile can be controlled and locked by remote operation, and the operation unit 12 is locked, so that the vehicle is tampered with, the car is stolen, and the mobile phone 1 is illegally operated. It can be prevented from being used.

  Next, the operation of the mobile phone 1 when the door lock actuator 23 is controlled and unlocked by remote operation from the telephone 5 will be described with reference to FIG. First, the user dials the telephone number of the portable telephone 1 from the telephone 5 that is registered as the designated telephone number or is a public telephone, and makes a call to the portable telephone 1 that is placed in the car. In the normal standby state (step S31), the CPU 11 determines whether there is an incoming call depending on whether there is an incoming call notification from the wireless communication unit 14 (step S32). If there is an incoming call as a result of this determination, the CPU 11 monitors the state of the operation unit 12 and determines whether an incoming call response operation has been performed (step S33). If there is an incoming call response, the CPU 11 switches to the call mode and performs a voice call until the call is disconnected (steps S34 and S35). On the other hand, when there is an incoming call but no incoming call response operation is performed, the CPU 11 executes a missed call process (step S36). Then, the CPU 11 specifies the caller telephone number of the incoming call, and determines whether or not the specified caller telephone number matches the designated telephone number stored in the memory 15 (step S37). When the caller telephone number is not the designated telephone number, the CPU 11 ends the process after executing the missed call process and enters a normal standby state.

  Next, when the caller telephone number is the designated telephone number, the CPU 11 counts the number of incoming calls from the designated telephone number and starts a timer for measuring the elapsed time. Then, the CPU 11 determines whether or not the remote auto lock function is set (step S38). If not set, the CPU 11 terminates the process after executing the missed call process and enters a normal standby state. On the other hand, if the remote auto-lock function has been set, the CPU 11 acquires the elapsed time from the first incoming call from the designated telephone number from the timer, and designates the elapsed time and the designation stored in the memory 15. The time is compared to determine whether or not the elapsed time is within the specified time (step S39). If the elapsed time exceeds the specified time, the missed call process is executed and the process ends and the normal standby state It becomes.

  Next, if the elapsed time is within the designated time, the CPU 11 determines whether or not the count value of the number of incoming calls from the designated telephone number matches the designated number of incoming calls at the time of unlocking stored in the memory 15. (Step S40) If they do not match, the missed call process is executed and then the process is terminated and a normal standby state is entered. On the other hand, when the number of incoming calls from the designated telephone number matches the number of designated incoming calls stored in the memory 15, that is, the number of incoming calls from the same designated telephone number within the designated time is unlocked. If it coincides with the designated number of incoming calls at that time, the CPU 11 determines that the condition for unlocking is satisfied. If the conditions for unlocking are satisfied, the CPU 11 reads out the voice data of the voice guidance stored in advance in the memory 15 and sends this voice data to the telephone 5 via the wireless communication unit 14 ( Step S41). This voice guidance notifies the caller of the caller that the operation unit 12 of the mobile phone 1 is unlocked and the electronic key 18 is activated.

  Next, the CPU 11 releases the lock to validate the operation unit 12 (step S42), and instructs the power supply control unit 20 to resume power supply. Receiving this, the power supply control part 20 restarts supply of electric power from the battery 19 with respect to the electronic key 18 (step S43). As a result, electric power is supplied to the electronic key 18 and transmission of the vehicle identification information is resumed as a response to the inquiry signal from the RF circuit 22, so that the control unit 21 causes the electronic key 18 to approach the predetermined range. Assuming that the door is locked, an instruction to unlock the door lock actuator 23 is output. In response to this, the door lock actuator 23 unlocks the door of the automobile.

  Next, the CPU 11 reads out voice guidance voice data stored in advance in the memory 15 and sends the voice data to the telephone 5 via the wireless communication unit 14 (step S44). This voice guidance notifies the caller of the caller that the door has been unlocked by enabling the electronic key 18.

  Therefore, even if the user forgets to place the mobile phone 1 with the electronic key 18 in the automobile and the remote auto-lock of the mobile phone 1 is set, the user can make a call from the phone 5 to the mobile phone 1. By doing so, the electronic key 18 can be activated, so that the automatic lock device of the automobile can be controlled and unlocked by remote operation, and the locked operation unit 12 is unlocked and used. It becomes possible.

  In the above description, the control operation with respect to the automatic lock device mounted on the automobile has been described as an example. However, the present invention is not limited to an automatic lock device that locks or unlocks using an electronic key. The present invention can also be applied to an automatic locking device provided at the front door of the door. For example, when you forget to leave a mobile phone with an electronic key in your house, go out without carrying a mobile phone, and when you notice that you are not carrying a mobile phone when you are out, you have a phone with a designated phone number such as a public phone. By making a call so as to satisfy a predetermined condition, the entrance door can be locked by remote control.

  The mobile terminal of the present invention includes a mobile phone using mobile communication, a personal digital assistant (PDA) having a mobile communication function, a mobile terminal, a car navigation device, and the like. The electronic key 18 may be detachable from the mobile phone 1. In this case, the electronic key 18 is not provided with a power source, and the mobile phone 1 and the electronic key 18 are connected to each other by a power line that can be turned on / off by the power control unit 20 when the electronic key 18 is attached to the mobile phone 1. An interface to be connected may be provided in both the mobile phone 1 and the electronic key 18. In this way, even when the automatic lock device to be controlled changes, it is possible to remotely operate the automatic lock device without preparing a new mobile phone 1. Further, the identification information held in the electronic key 18 (vehicle identification information in the case of an automobile) may be downloaded via the wireless communication unit 14.
