  Next, after the vehicle 10 is dispatched to the dispatch area 102, the operation when the first parking lot management device 21 cancels dispatch is described when the user of the vehicle 10 does not come to the dispatch area 102. .

  FIG. 6 is a sequence diagram showing an operation when the vehicle 10 arrives at the dispatch area 102.

When the third parking lot management device 23 determines that the vehicle 10 has arrived at the dispatch area 102, the third parking lot management device 23 transmits a first arrival notice to the first parking lot management device 21 (step ST11).
The first arrival notification includes the license plate number information of the vehicle 10 that has arrived in the dispatch area 102, the dispatch position ID of the position where the vehicle 10 is stopped, and the like.

When receiving the first arrival notification from the third parking lot management device 23, the first parking lot management device 21 transmits the second arrival notification to the portable terminal 30 (step ST12).
The second arrival notification includes the time when the vehicle 10 arrives at the dispatch area 102, the dispatch position ID, and the like. The time when the vehicle 10 arrives at the dispatch area 102 is generated by the time information generation unit 21c of the first parking lot management device 21.

  The first parking lot management device 21 determines whether or not to cancel the allocation of the vehicle 10 (step ST13). This determination is referred to as vehicle allocation cancelability determination. Details of the determination of whether or not to cancel the vehicle allocation will be described later with reference to the flowchart of FIG.

In step ST13, when it determines with the 1st parking lot management apparatus 21 canceling the dispatch of the vehicle 10, it transmits a dispatch cancellation notification with respect to the portable terminal 30 which is the outside (step ST14).
The dispatch cancellation notification includes information indicating that the dispatch of the vehicle 10 is canceled, the parking position ID of the vehicle 10 in the parking area 101, and the like.

The first parking lot management device 21 transmits a vehicle dispatch cancellation instruction to the vehicle 10 (step ST15).
The vehicle allocation cancellation instruction is an instruction to move the vehicle 10 to a parking position in the parking area 101 (hereinafter referred to as the original parking position) where the vehicle 10 was parked before being allocated to the vehicle allocation area 102. The dispatching cancel instruction includes the parking position ID of the original parking position.

The details of the vehicle allocation cancelability determination process performed by the first parking lot management device 21 in step ST13 will be described.
FIG. 7 is a flowchart showing the operation of the vehicle allocation cancelability determination process.

  As shown in step ST <b> 11, when the third parking lot management device 23 determines that the vehicle 10 has arrived in the dispatch area 102, the third parking lot management device 23 transmits a first arrival notification to the first parking lot management device 21. . The time information generation unit 21c generates a time elapsed after receiving the first arrival notification, that is, a time during which the vehicle 10 stops in the dispatch area 102 (hereinafter referred to as a stop time), and controls the stop time. It outputs to the part 21b (step ST21).

The control part 21b determines whether the stop time acquired from the time information generation part 21c is larger than a 1st threshold value (step ST22).
Control part 21b progresses to processing of Step ST23, when stop time is larger than the 1st threshold (Step ST22; YES). Note that the process may proceed to step ST25 without proceeding to step ST23.
On the other hand, the control part 21b returns to the process of step ST21, when stop time is below the 1st threshold value (step ST22; NO). The first threshold is, for example, about 10 minutes.

The control unit 21b receives information on the number of vehicles 10 stopped in the dispatch area 102 from the third parking lot management device 23 (step ST23).
The 3rd parking lot management apparatus 23 performs a dispatch vehicle determination process, and produces | generates the said number information. Details of the dispatched vehicle determination process will be described later with reference to the flowchart of FIG.
The control unit 21b determines whether or not the number of vehicles 10 stopped in the vehicle allocation area 102 is larger than the second threshold (step ST24).
When the number of vehicles 10 parked in the dispatch area 102 is larger than the second threshold (step ST24; YES), the control unit 21b determines the dispatch cancellation and outputs a message to that effect to the command unit 21e (step ST24). ST25). The command unit 21 e transmits a vehicle dispatch cancellation instruction to the vehicle 10.

  On the other hand, the control part 21b progresses to the process of step ST26, when the number of the vehicles 10 which stop in the dispatch area 102 is below a 2nd threshold value (step ST24; NO). The second threshold value is, for example, two.

  The control unit 21b determines whether or not a vehicle dispatch cancellation request has been received (step ST26). The user can operate the vehicle allocation application of the mobile terminal 30 and transmit a vehicle allocation cancellation request to the first parking lot management device 21. The vehicle allocation cancellation request received by the first parking lot management device 21 is stored in the storage unit 21 d of the first parking lot management device 21. The control unit 21b confirms whether the vehicle allocation cancellation request is stored in the storage unit 21d, and performs the determination in step ST26.

When it determines with the control part 21b having received the vehicle allocation cancellation request | requirement (step ST26; YES), it progresses to the process of step ST25 and confirms vehicle allocation cancellation.
On the other hand, when it determines with the control part 21b not having received the dispatch cancellation request (step ST26; NO), it progresses to the process of step ST27.

  The control unit 21b determines whether or not a stop extension request in the dispatch area 102 has been received (step ST27). The user can operate the vehicle allocation application of the mobile terminal 30 and transmit a stop extension request in the vehicle allocation area 102 to the first parking lot management device 21. The stop extension request received by the first parking lot management device 21 is stored in the storage unit 21 d of the first parking lot management device 21. The control part 21b confirms whether the stop extension request | requirement is stored in the memory | storage part 21d, and performs determination of step ST27.

When it determines with the control part 21b having received the stop extension request in the dispatch area 102 (step ST27; YES), it progresses to the process of step ST28.
On the other hand, when it determines with the control part 21b not having received the stop extension request | requirement in the dispatch area 102 (step ST27; NO), it progresses to the process of step ST25 and determines dispatch cancellation.

The control unit 21b determines whether or not the number of times the stop extension request is received in the dispatch area 102 is larger than the third threshold (step ST28).
If the controller 21b determines that the number of stop extension requests received in the vehicle allocation area 102 is greater than the third threshold (step ST28; YES), the control unit 21b proceeds to the process of step ST25 and determines vehicle allocation cancellation.
On the other hand, if the control unit 21b determines that the number of stop extension requests received in the dispatch area 102 is equal to or less than the third threshold (step ST28; NO), the control unit 21b returns to the process of step ST21. At this time, the control unit 21b instructs the time information generation unit 21c to reset the stop time of the vehicle 10 and to measure again.
The third threshold is, for example, twice. The user can operate the vehicle allocation application of the mobile terminal 30 to make a stop extension request in the vehicle allocation area 102, but does not accept the stop extension request when the number of stop extension requests exceeds a predetermined number. I am going to do that.

  In the above, if the number of vehicles 10 parked in the dispatch area 102 is equal to or less than the second threshold value in step ST24 (step ST24; NO), whether or not a dispatch cancellation request has been received. However, the process of step ST26 may be omitted and the process may proceed to step ST27.

  As described in step ST23 above, the control unit 21b receives the number information from the third parking lot management device 23. Next, a dispatched vehicle determination process performed by the third parking lot management device 23 will be described. FIG. 8 is a flowchart showing the operation of the dispatched vehicle determination process.

The control unit 23b analyzes the imaging data acquired from the second camera 23c (step ST31).
