[Configuration of vehicle door lock system]
FIG. 1 is a block diagram of a vehicle door lock system 1 according to the present embodiment. The vehicle door lock system 1 includes a door handle 10 and a control module 20. The door handle 10 and the control module 20 are mounted on the vehicle 30 and are connected so that signals can be transmitted and received. The vehicle door lock system 1 authenticates the portable device 40 by performing wireless communication with the portable device 40 carried by the user of the vehicle 30. When the vehicle door lock system 1 detects an operation of a predetermined locking / unlocking instruction to the door handle 10 by the user, the control module 20 locks / unlocks the door. The control module 20 may be built in the door handle 10. Hereinafter, each structure of the vehicle door lock system 1 will be described.

  The door handle 10 includes an operation detection unit 11 and an indicator 12. FIG. 2 is a schematic configuration diagram of the door handle 10.

  The operation detection unit 11 detects an operation of a locking / unlocking instruction by a user of the vehicle 30. As shown in FIG. 2, the door handle 10 is provided with three operation detection units 11a to 11c. The operation detection units 11 a to 11 c are arranged at substantially equal intervals in the extending direction of the door handle 10. In the present embodiment, each of the operation detection units 11a to 11c is a touch sensor. The touch sensor can detect the presence or absence of contact by the user. When the user's hand or the like comes into contact, each of the operation detection units 11a to 11c transmits a signal indicating that there is a contact to the control module 20. For example, when the user slides the door handle 10 shown in FIG. 2 from the operation detection unit 11a toward the operation detection unit 11c while bringing the finger into contact with the door handle 10, the operation detection unit 11a, the operation detection A signal indicating that there is contact in the order of the unit 11b and the operation detection unit 11c is transmitted to the control module 20.

  The indicator 12 is provided in the vicinity of the operation detection units 11a to 11c, and notifies the user of the operation order to the operation detection units 11a to 11c. In this Embodiment, as shown in FIG. 2, the indicator 12 is comprised from three indicator 12a-12c provided corresponding to each of operation detection part 11a-11c. Each indicator 12a to 12c is lit to notify the user to operate a position near the lit indicator 12.

  The control module 20 includes a wireless communication unit 21, a determination unit 22, and a door lock control unit 23.

  The wireless communication unit 21 performs wireless communication with the portable device 40 to authenticate the portable device 40. Specifically, the wireless communication unit 21 periodically transmits a request signal toward a predetermined range outside the vehicle. When the portable device 40 exists within the predetermined range, the portable device 40 that has received the request signal transmits a response signal including an ID code to the wireless communication unit 21. The wireless communication unit 21 that has received the response signal authenticates the portable device 40 when the ID code of the portable device 40 matches the ID code uniquely determined for the vehicle 30.

  The determination unit 22 determines whether the door lock of the vehicle 30 is locked or unlocked by communicating with a door locking / unlocking ECU (not shown). In the following description, in order to simplify the description, the unlocked state includes a state where all doors are locked (hereinafter referred to as “locked state”) and a state where all doors are unlocked. (Hereinafter referred to as “unlocked state”).

  Based on the determination result of the determination unit 22, the door lock control unit 23 causes the indicator 12 to display the operation order to the operation detection units 11a to 11c. Specifically, when the determination unit 22 determines that the vehicle 30 is locked, the door lock control unit 23 reads a predetermined first operation order from a memory (not shown). The first operation order is an operation order of the operation detection units 11a to 11c for bringing the vehicle 30 from the locked state to the unlocked state. Then, the door lock control unit 23 causes the indicator 12 to display the first operation order. In the present embodiment, the first operation order is described as the order of the operation detection unit 11a, the operation detection unit 11b, and the operation detection unit 11c. FIG. 3A is a diagram for explaining that the first operation order is displayed on the indicator 12. As shown to Fig.3 (a), the door lock control part 23 controls the indicator 12 to repeat lighting in order of the indicator 12a, the indicator 12b, and the indicator 12c.

  On the other hand, when the determination unit 22 determines that the vehicle 30 is in the unlocked state, the door lock control unit 23 reads a predetermined second operation order from the memory. The second operation order is an operation order to the operation detection unit 11 for changing the vehicle 30 from the unlocked state to the locked state. Then, the door lock control unit 23 causes the indicator 12 to display the second operation order. In the present embodiment, the second operation order is described as the order of the operation detection unit 11c, the operation detection unit 11b, and the operation detection unit 11a. FIG. 3B is a diagram for explaining that the second operation order is displayed on the indicator 12. As shown in FIG. 3B, the door lock control unit 23 controls the indicator 12 to repeat lighting in the order of the indicator 12c, the indicator 12b, and the indicator 12a.

  In the above description, the door lock control unit 23 controls the indicators 12a to 12c to be repeatedly turned on. However, the indicators 12a to 12c may be turned on only once. .

  Further, the door lock control unit 23 determines that the order in which the operation detection units 11a to 11c are operated based on the signals received from the operation detection units 11a to 11c when the vehicle 30 is locked is the first operation. When the order is followed, the door lock of the vehicle 30 is unlocked. On the other hand, when the vehicle 30 is in the unlocked state, the door lock control unit 23 determines that the operation order of the operation detection units 11a to 11c is based on the signals received from the operation detection units 11a to 11c. When the operation sequence is followed, the door lock of the vehicle 30 is locked.

[Locking / unlocking operation of vehicle door lock system]
Next, the locking / unlocking operation of the vehicle door lock system 1 will be described. FIG. 4 is a flowchart showing the locking / unlocking operation of the vehicle door lock system 1.

If the verification is established, the process proceeds to step S12. If the verification is not established, the locking / unlocking operation is terminated.

  Subsequently, in step S12, the determination unit 22 determines whether the vehicle 30 is in a locked state or an unlocked state. If it is locked, the process proceeds to step S13. If it is unlocked, the process proceeds to step S17.

  If it is determined in step S12 that the door is locked, the door lock control unit 23 causes the indicator 12 to display the first operation order in step S13.

  Subsequently, in step S <b> 14, the door lock control unit 23 determines whether or not an operation has been performed on the operation detection unit 11. Specifically, the door lock control unit 23 determines that an operation has been performed on the operation detection unit 11 when receiving a signal from the operation detection unit 11 within a predetermined time. On the other hand, when the door lock control unit 23 does not receive a signal from the operation detection unit 11 within a predetermined time, the door lock control unit 23 determines that the operation detection unit 11 has not been operated. If an operation has been performed on the operation detection unit 11, the process proceeds to step S <b> 15, and if no operation has been performed on the operation detection unit 11, the locking / unlocking operation is terminated.

  Subsequently, in step S15, the door lock control unit 23 determines whether or not the operation detected by the operation detection unit 11 is in accordance with the first operation order. If the first operation order is followed, the process proceeds to step S16. If the first operation order is not followed, the locking / unlocking operation is terminated.

  Subsequently, in step S16, the door lock control unit 23 unlocks the door lock and ends the locking / unlocking operation.

  If it is determined in step S12 that the door is unlocked, the door lock control unit 23 causes the indicator 12 to display the second operation order in step S17.

  Subsequently, in step S <b> 18, the door lock control unit 23 determines whether or not an operation has been performed on the operation detection unit 11. If an operation has been performed on the operation detection unit 11, the process proceeds to step S19, and if no operation has been performed on the operation detection unit 11, the locking / unlocking operation is terminated.

  Subsequently, in step S19, the door lock control unit 23 determines whether the operation detected by the operation detection unit 11 is in accordance with the second operation order. If the second operation order is followed, the process proceeds to step S20. If the second operation order is not followed, the locking / unlocking operation is terminated.

  Subsequently, in step S20, the door lock control unit 23 locks the door lock and ends the locking / unlocking operation.
