(Operation of storage unit lock system 2)
FIG. 4 is a flowchart showing the operation of the storage unit locking system according to the embodiment of the present invention. Hereinafter, the operation of the storage portion locking system 2 will be described with reference to FIGS. First, based on the operating state of the courtesy switch 6, the main ECU 100 determines whether or not a person (owner or the like) has entered the passenger compartment of the vehicle 1, that is, whether or not a person has entered the vehicle 1 (S401). .

  Next, the main ECU 100 determines whether or not the portable device 3 is in the passenger compartment (S402). The main ECU 100 drives the verification unit 101 and transmits an ID transmission request to the portable device 3. The portable device 3 receives the ID transmission request from the indoor transmission / reception unit 103 of the verification unit 101, and transmits the key ID 31 from the antenna 35 by the portable device ECU 30 and the transmission unit 34. The collation unit 101 receives and demodulates the key ID 31 by the antenna 102 and the indoor transmission / reception unit 103, further compares the key ID 31 and the vehicle ID 105A by the authentication ECU 104, and when both match (S402: Yes), the portable device 3 is determined to be in the passenger compartment. Moreover, when it does not correspond (S402: No), it determines with the person not having boarded.

  When it is determined that a person is not in the vehicle 1 (S402: No), the main ECU 100 keeps it as it is when the door 15a is in the locked state. When the door 15a is in the unlocked state, the main ECU 100 drives the drive unit 15e (S413), and puts the lock mechanism unit 15f in the locked state (S414). In this state, since the door 15a of the glove box 15 remains locked, even if a third person gets on the vehicle 1, the door 15a cannot be opened and the bullet key 4 cannot be taken out.

  When the authentication ECU 104 determines that the portable device 3 is present in the vehicle interior (S402: Yes), the main ECU 100 drives the drive unit 15e (S403) and operates the lock mechanism unit 15f in the unlocking direction (S404). ), The door 15a of the glove box 15 can be opened. Here, if the owner opens the door 15a as shown in FIG. 2, the bullet key 4 can be taken out from the bullet key storage part 15b (S405). After removing the bullet key 4, the door 15a is closed by hand. In the case of the present embodiment, the door 15a is manually opened and closed, so that the door 15a after opening is not left open from the viewpoint of security and crime prevention, and is quickly closed after use. .

  Thereafter, it is determined again whether or not the portable device 3 is in the passenger compartment (S406), that is, whether or not the owner gets out of the vehicle 1. This determination is performed by the ID verification of the authentication ECU 104 as in step S402. When the authentication ECU 104 determines that the portable device 3 is in the passenger compartment, that is, the owner is continuing to board (S406: Yes), the main ECU 100 drives the drive unit 15e and the lock mechanism unit 15f. The door 15a is unlocked (S407) so that the door 15a can be opened at any time by the owner.

  In step S406, when the authentication ECU 104 cannot receive the key ID 31 (S406: No), the portable device 3 is not in the passenger compartment (the owner is away from the vehicle 1 and between the bullet key 4 and the collating unit 101). And the door 15a is locked by driving the drive unit 15e and the lock mechanism unit 15f (S408).

  The determination in step S406 may be performed based on the on / off operation of the courtesy switch 6. The determination in step S406 is that the authentication ECU 104 determines that the outdoor verification matches when the radio wave of the portable device 3 outside the vehicle 1 is received by the antenna 106 and the outdoor transmission / reception unit 107 of the verification unit 101. The determination may be made by determining that the portable device 3 is not in the passenger compartment.

  Even if the ID can be received by the collation unit 101, if the ID is different from the key ID 31 and the vehicle ID 105A, for example, it is determined that a third party has boarded the vehicle 1, and the portable device 3 is Continue locking as if you were not indoors.

  At this point, the owner can hand the bullet key 4 to a hotel man (valet parking staff, etc.) (S409). A hotelman who has received the bullet key 4 from the owner gets on the vehicle 1 with the bullet key 4.

  Next, in order to confirm that the hotel man has boarded the vehicle 1, the collation unit 101 confirms whether the key entered in the vehicle is the portable device 3 or the bullet key 4 from the ID received by the indoor transmission / reception unit 103. (S410). When the ID received by the indoor transmission / reception unit 103 is the key ID 31, the authentication ECU 104 confirms that the portable device 3 is in the vehicle interior, that is, while the owner's boarding continues or re-boarding, by comparing the vehicle ID 105 </ b> A with the key ID 31. (S410: key ID31 = vehicle ID 105A), the process returns to step S403, and the subsequent processes are executed again.

  Further, when the ID received by the indoor transmission / reception unit 103 is the key ID 41, the authentication ECU 104 determines the presence of the bullet key 4 by the main ECU 100 based on the result of the verification between the vehicle ID 105B and the key ID 41 by the authentication ECU 104. (S410: Key ID 41 = Vehicle ID 105B), the locking of the door 15a of the glove box 15 is continued (S411). Therefore, a third person such as a hotel man cannot open the door 15a of the glove box 15.

  Since the hotel man who has deposited the bullet key 4 has already collated the ID through communication between the bullet key 4 and the collation unit 101, the engine can be started by the bullet key 4. In this case, when the hotel man performs an engine start operation, the main ECU 100 issues an engine control permission instruction to the engine ECU 5. The hotel man moves the vehicle 1 to a parking lot or the like, locks the door, and then returns the bullet key 4 to the owner of the vehicle 1 or stores it at the front.

  Moreover, although this invention demonstrated the case where a master key was the portable device 3, even if it is a card key, the operation and operation | movement are the same as that of the case of the portable device 3 mentioned above.
