When the actuator link mechanism operates, the door lock mechanism is unlocked, and the door panel is opened.

  On the other hand, when the key rotor is rotated in the other direction from the neutral position by the operation of inserting and rotating the match key into the cylinder lock in the unlocked state of the door lock mechanism, this rotation is transmitted to the key lever mechanism via the cylinder locking rod. Then, the actuator link mechanism is operated by the operation of the key lever mechanism, and the door lock mechanism is changed from the unlocked state to the locked state.

  By the way, in this type of locking / unlocking device, in order to obtain a good design, a door panel having a recess opening in the panel surface and a door lock mechanism disposed in the recess of the door panel is locked / unlocked. And a door handle that has a shutter portion that opens and closes a key insertion / extraction hole of the cylinder lock and is rotatably disposed in a recess of the door panel (Patent Document) 1).

[Operation of Locking / Unlocking System 1]
Next, the operation of the locking / unlocking system 1 shown in the present embodiment will be described with reference to FIGS. FIG. 5 is a flowchart for explaining the operation when the door lock mechanism of the locking / unlocking system according to the first embodiment of the present invention is unlocked. FIG. 6 is a flowchart for explaining the operation when the door lock mechanism of the locking / unlocking system according to the first embodiment of the present invention is locked.

  First, in order to switch the door lock mechanism 10 from the locked state to the unlocked state in the closed state of the door 4, a driver or the like carrying the portable device 2 approaches the automobile A (step S1 in FIG. 5), and the door handle. When 5 is rotated from the initial position c to the position a, the switch pressing portion 51 of the door handle 5 presses the contact 60 of the switch 6 (step S2 in FIG. 5).

  In this case, since the switching is performed by pressing the switch 6, the switch 6 outputs a switch signal for unlocking to the controller 7, and the controller 7 inputs the switch signal and sends the control signal for transmitting the LF signal to the door handle. 5 to the transceiver 15.

  Next, when a control signal for LF signal transmission is input from the controller 7 in the transceiver 15, the LF signal is transmitted outside the automobile A (step S3 in FIG. 5).

  Thereafter, when the portable device 2 receives the LF signal from the transceiver 15, an RF signal is transmitted (step S4 in FIG. 5).

  When the transceiver 15 receives the RF signal from the portable device 2, it outputs an RF signal for verification to the controller 7. When the controller 7 receives the verification RF signal, the controller 7 compares the ID code registered in advance with the ID code included in the verification RF signal (step S5 in FIG. 5). As a result, if the two ID codes match (YES in step S5), the controller 7 outputs an unlocking control signal to the first actuator 8 (step S6 in FIG. 5). When the unlocking control signal is input to the first actuator 8, the unlocking drive signal is output to the door lock mechanism 10 (step S7 in FIG. 5).

  In step S5 in FIG. 5, if the codes are different from each other (NO in step S5 in FIG. 5), the process returns to step S2 in FIG.

  Thereafter, when the door lock mechanism 10 is unlocked by inputting a drive signal for unlocking from the first actuator 8, the first sensor 11 detects the unlocked state of the door lock mechanism 10 and opens the door. The sensor signal is output to the controller 7. Therefore, the controller 7 inputs a door opening sensor signal from the first sensor 11 and outputs a door opening control signal to the second actuator 9. The second actuator 9 inputs a door opening control signal from the controller 7 and outputs a door opening drive signal to the door opening / closing mechanism 13. As a result, the door opening / closing mechanism 13 operates to open the door 4 (step S8 in FIG. 5).

  Next, in order to switch the door lock mechanism 10 from the unlocked state to the locked state in the closed state of the door 4, a driver or the like carrying the portable device 2 approaches the automobile A (step S <b> 1 in FIG. 6), When the handle 5 is rotated from the initial position c to the position a, the switch pressing portion 51 of the door handle 5 presses the contact 60 of the switch 6 (step S2 in FIG. 6).

  In this case, since the switching is performed by pressing the switch 6, the switch 6 outputs a locking switch signal to the controller 7, and the controller 7 inputs the switch signal and sends the control signal for transmitting the LF signal to the door handle 5. To the transceiver 15.

  In step S1, if the door 4 is not closed, the door 4 is arranged at a predetermined rotation (opening / closing) position by an operation.

  In this case, when the second sensor 12 detects the open / closed state of the door 4, a sensor signal for closing the door is output to the controller 7. Therefore, the controller 7 inputs a door closing sensor signal from the second sensor 12 and outputs a door closing control signal to the second actuator 9. The second actuator 9 receives a door closing control signal from the controller 7 and outputs a door closing drive signal to the door opening / closing mechanism 13. As a result, the door opening / closing mechanism 13 is operated and the door 4 is closed.

  Next, when a control signal for LF signal transmission is input from the controller 7 in the transceiver 15, the LF signal is transmitted outside the automobile A (step S3 in FIG. 6).

  Thereafter, when the portable device 2 receives the LF signal from the transceiver 15, an RF signal is transmitted (step S4 in FIG. 6).

  When the transceiver 15 receives the RF signal for verification from the portable device 2, it outputs the RF signal for verification to the controller 7. When the controller 7 receives the RF signal, the controller 7 collates the ID code registered in advance with the ID code included in the RF signal for collation (step S5 in FIG. 6). As a result, when both codes match (YES in step S5), the controller 7 outputs a control signal for locking to the first actuator 8 (step S6 in FIG. 6). When the first actuator 8 receives a locking control signal, it outputs a locking drive signal to the door lock mechanism 10 (step S7 in FIG. 6).

  In step S5 in FIG. 6, if the codes are different from each other (NO in step S5 in FIG. 6), the process returns to step S2 in FIG.

  Thereafter, the door lock mechanism 10 is locked by inputting a drive signal for locking from the first actuator 8 (step S8 in FIG. 6).
