  In a general management system, an application for using a vehicle is made by designating a vehicle use date and time and a vehicle use location desired by the user. When the management system accepts the application from the user, the vehicle to be lent to the user and the place to use are determined in the order in which the application is accepted.

  However, in the above management system, when the usage time and the usage location overlap among a plurality of users, the user who can use the vehicle is determined in the order in which the application is accepted. There is a high possibility that the user is determined to be unusable and the number of users who can use the vehicle is small.

  The problem to be solved by the present invention is to provide a vehicle management method and a vehicle management system that increase the number of users who can use a vehicle when applications for using the vehicle overlap.

  The present invention selects a station that lends or returns a vehicle as a utilization station based on a utilization request received from a user, and determines whether the utilization station and the utilization time of the vehicle overlap among a plurality of users. If it is determined that they overlap, the above-mentioned problem is solved by changing the use start time within the range of changeable time so that the number of users using the vehicle is maximized.

  According to the present invention, it is possible to increase the number of users who can use the vehicle.

FIG. 1 is a block diagram of a car sharing system (vehicle management system) according to the present embodiment. FIG. 2 is a block configuration diagram illustrating functional blocks of the server-side control device. As shown in FIG. 1, the car sharing system of this embodiment includes a management server 100, a plurality of shared vehicles 200 used for car sharing, and a plurality of users that can communicate with the vehicle management server 100 via the Internet 300. Terminal 400. In FIG. 1, only two shared vehicles 200 are shown, but the car sharing system of the present embodiment includes a large number of shared vehicles 200. And in the car sharing system of this embodiment, many shared vehicles 200 are each parked in the predetermined parking space provided in each place, and the specific many users are parked in the desired parking space. The vehicle 200 can be selected and used.

  As shown in FIG. 1, the shared vehicle 200 can communicate with the management server 100 and includes an in-vehicle device 210 and a communication device 220. The in-vehicle device 210 includes information on the use start time and use end time of the shared vehicle 200, travel distance information, own vehicle position information, vehicle speed information, battery remaining amount information, vehicle power switch on / off Information or the like is transmitted from the communication device 220 to the communication device 120 provided in the management server 100 by wireless communication. The communication device 220 receives information transmitted from the management server 100 as a signal.

  In addition, as a method for the in-vehicle device 210 to acquire information on the own vehicle position, for example, a radio wave transmitted from a positioning satellite by a GPS (Global Positioning System) provided in each shared vehicle 200 is received every predetermined time. Thus, a method of acquiring real-time position information of each shared vehicle 200 can be mentioned.

  The user terminal 400 is a terminal owned by a specific number of users who use the car sharing system of the present embodiment, and can communicate with the communication device 120 provided in the management server 100 via the Internet 300. In the car sharing system of the present embodiment, each user can make a use application for the shared vehicle 200 using the user terminal 400.

  Here, the use application of the shared vehicle 200 may be an immediate use application in which the user starts using the shared vehicle 200 immediately after the use application, or the use for the user to use the shared vehicle 200 in the future. You may apply for a reservation.

  Further, in the car sharing system of the present embodiment, when the user makes an application for the use of the shared vehicle 200 by the user terminal 400, the user sets a planned rental site for renting the shared vehicle 200, and is shared. After the vehicle 200 is used, a scheduled return location for returning is set.

  Examples of the user terminal 400 include various mobile terminals such as a mobile phone and a PDA in addition to a personal computer. When the user terminal 400 is a mobile phone, vehicle information communicated by the communication device 120 is read into the user terminal 400 by wireless communication based on various wireless device standards, and the user terminal 400 receives vehicle information and the like. You may transmit to the management server 100. In FIG. 1, four terminals are shown as examples of the user terminal 400. However, the number of users using the user terminal 400 and the car sharing system of the present embodiment is not particularly limited.

  The management server 100 includes a control device 110, a communication device 120, and a database 130.

  The communication device 120 is a device for communicating with the user terminal 400 owned by each user via the Internet 300 and the communication device 220 provided in the shared vehicle 200 by wireless communication. The communication device 120 wirelessly communicates information on the use start time and use end time of the shared vehicle 200, information on the travel distance, information on the vehicle position, and the like from the in-vehicle device 210, and information on the vehicle position from the user terminal 400. Information on the application for use of the shared vehicle 200, information on a planned rental site and a planned return site selected by the user, and the like are acquired. The information on the usage time of the shared vehicle 200 includes time information related to the usage of the shared vehicle 200 such as the usage start time, the width of the usage start time, the scheduled usage time length, and the usage end time. The usage application information includes vehicle information desired to be used, service usage history, member registration information, and the like.

  The database 130 is a storage device for storing, for each shared vehicle 200, usage reception information, usage location information, location information of parking spaces that are parked, and the like. The use location information is information on a departure location (scheduled rental location) and an arrival location (scheduled return location). The use acceptance information and the use location information are transmitted from the user terminal 400 when the user makes an application for the use of the shared vehicle 200, the selection of the available vehicle, and the use location through the user terminal 400. This is information generated for each shared vehicle 200 based on the information that has been made. Further, when the user of the car sharing system is limited to members, the database 130 also stores registered member information, identification information of the user terminal 400 registered by the member, and the like.

  Further, the database 130 stores information on a plurality of parking spaces for parking the shared vehicle 200. Specifically, the database 130 stores position information of a plurality of parking spaces provided in a predetermined area. In the car sharing system of the present embodiment, the parking space is a parking lot for parking the shared vehicle 200, and an area where a plurality of parking spaces are provided is a parking station.

  As shown in FIG. 1, the control device 110 of the management server 100 includes a ROM (Read Only Memory) 112 in which various programs are stored, and a CPU (Central Processing Unit) as an operation circuit for executing the programs stored in the ROM 112. ) 111 and a RAM (Random Access Memory) 113 that functions as an accessible storage device.

  In order to manage the car sharing system according to this embodiment, the control device 110 manages a reservation management function for managing a reservation from a user, a vehicle management function for managing the shared vehicle 200, and a station for managing the state of the station. Provide management functions. The control device 110 can execute each function by cooperation of software for realizing the above functions and the hardware described above. Moreover, the control apparatus 110 has the reservation management part 11, the vehicle management part 12, and the station management part 13 as a functional block for exhibiting each of these functions, as shown in FIG.

  Below, each function which the control apparatus 110 of the management server 100 implement | achieves is each demonstrated using FIG. Further, control on the vehicle side will be described as necessary. FIG. 2 is a block configuration diagram illustrating functional blocks of the control device 110.

  First, the control device 110 accepts an application for the use of a vehicle from the user by the reservation management unit 11. Specifically, when the user operates the user terminal 400 to apply for the use reservation of the shared vehicle 200, the reservation management unit 11 uses the use reservation information transmitted from the user terminal 400. Accept application.

  The usage reservation information includes departure station (rental station) information, arrival station (return station) information, usage start time, usage end time, and the like. The information on the departure station indicates the planned rental location of the vehicle, and the information on the arrival station indicates the planned return location of the vehicle. The use start time is a scheduled time when the vehicle is rented, and is a scheduled use start time of the vehicle. The use start time is also the scheduled departure time of the vehicle. The use end time is a scheduled time when the vehicle is returned, and is a scheduled use end time of the vehicle. The use end time is also the estimated arrival time of the vehicle. The user uses the user terminal 400 to specify a departure station and an arrival station from the station list. Using the user terminal 400, the user inputs a use start time and a use end time. Further, the user uses the user terminal 400 to input a changeable time (changeable time length) of the use start time in addition to the use start time and the use end time. The changeable time indicates the changeable range of the use start time that is allowed by the user. The changeable time is a time width that can be freely set by the user. The changeable time can be set in predetermined time increments, for example, in 5 minute increments. The user terminal 400 may communicate with the server 100 to display a station state and a vehicle state on a display for a designated station.

  The reservation management unit 11 selects a station from which the vehicle is rented and a station to which the vehicle is to be returned from the management target stations based on the use reservation received from the user. The station where the vehicle is rented corresponds to the departure station designated by the user, and the station where the vehicle is returned corresponds to the arrival station designated by the user. The reservation management unit 11 manages use reservation information including information on the selected station.

  When the reservation management unit 11 accepts the use reservation, the reservation management unit 11 stores the use reservation information in the database 130. The database 130 stores usage reservation information after associating the usage time length, station, and user information.

  The control device 110 may accept an application for immediate use as a vehicle use request from a user, not limited to the use reservation application as described above. For example, when the user wants to use the shared vehicle 200 immediately, the user confirms the current vacant state of the shared vehicle 200 and designates the vacant shared vehicle 200, the departure station, the arrival station, and the arrival time. The departure station is a station where the designated shared vehicle 200 is currently parked. When receiving an immediate use application from the user, the control device 110 selects a departure station and an arrival station based on the use request.

  The vehicle management unit 12 manages the usage state of the shared vehicle 200 to be managed. The vehicle management unit 12 stores the usage state of the shared vehicle 200 in the database 130. In addition, the vehicle management unit 12 manages the position of the shared vehicle 200 by communicating with the shared vehicle 200 using the communication device 120 and acquiring position information of the shared vehicle 200. The usage state of the shared vehicle 200 includes at least two states, a state where the vehicle is currently being used and a state where the vehicle is not currently used. For example, when the user wants to know the vacant state of the shared vehicle 200, the vehicle management unit 12 creates a list of available vehicles and transmits the created list to the reservation management unit 11. The reservation management unit 11 transmits a list of available vehicles to the user using the communication device 120. An available vehicle is a vehicle that is not currently used. The user who has received the list can check the available vehicle and the parking position of the available vehicle by checking the list or graphic information generated from the list on the display screen of the user terminal 400.

  The station management unit 13 manages the state of the station. The state of the station corresponds to an empty state of a parking space included in the station. The station management unit 13 manages the state where the vehicle is stopped in the parking space, the state where the parking space is vacant, the state where the vehicle is scheduled to be rented or returned, etc. as the state of the station. Yes. The station management unit 13 stores station state information in the database 130.

  Next, a reservation management function by the reservation management unit 11 will be described. When the reservation management unit 11 receives a use request as a use reservation from a user, the reservation management unit 11 stores information on the use time of the vehicle and information on the station in the database 130. At this time, the reservation management unit 11 does not permit the use of the vehicle, but makes a use request as a pre-reservation (advance reservation, reservation at a future (future) time exceeding 30 minutes from the current time). Accept. The database 130 stores use start time, use start time width, scheduled use time length, departure station, and arrival station information. The width of the use start time corresponds to the changeable time of the use start time. Note that the use end time may be stored in the database 130 instead of the scheduled use time length. Each time the reservation management unit 11 receives a use reservation from a user, the reservation management unit 11 stores information on the use reservation in the database 130.

  The reservation management unit 11 determines whether or not the current time has reached the use determination time. The use determination time is a time for finalizing the accepted use reservation, and is set to a time that is a predetermined time (for example, 30 minutes) before the use start time specified by the user. For example, when the user A designates 14:00 as the use start time and makes a use reservation, the reservation management unit 11 uses the user A at 13:30, which is 30 minutes before the use start time. It is determined whether or not to permit.

  When the reservation management unit 11 determines whether or not to allow the user to use the vehicle, the use start time within the range of the changeable time length so that the number of users using the shared vehicle 200 is maximized. Adjust. The control when the reservation management unit 11 confirms the use reservation will be described with reference to FIGS. 3 and 4. In the table of FIG. 3, the use start time is the time specified by the user when applying for use reservation, and is the use start time before the change. The longest use end time is a time when the use end time is the latest when the use start time is changed within the range of the use start time.

  Hereinafter, a specific example will be described. In a specific example, four users have already applied for use reservations as pre-reservations. Further, it is assumed that the application for use reservation is made in the order of user A, user B, user C, and user D. The utilization start time, utilization start time width (changeable time), scheduled utilization time length, departure station, and arrival station of the four users are as shown in the table of FIG. FIG. 4 is a conceptual diagram showing the usage time and the usage station relationship for each of the users A to D. The use determination time is a time 30 minutes before the use start time. For ease of explanation, it is assumed that the number of vehicles that can be used is one and that the common vehicle 200 is stopped only at ST1 among the five stations (ST1 to ST5).

  Of the four users, the reservation management unit 11 determines that the current time has reached the use determination time when the time is 30 minutes before the use start time of the user A with the earliest use start time, that is, at 13:00. . In order to determine whether or not to confirm the user A's use reservation, the reservation management unit 11 first determines the use station and use time of the user A, the use station and use time of the other users (users B to D), and It is determined whether or not there are duplicates.

  Duplication of the use station is not limited to the case where the departure station is duplicated among users or the arrival station is duplicated among users, and the departure station of one user and the arrival station of the other user are duplicated. It is also included if you are. The overlap of usage time includes a case where at least a part of the usage time of the user overlaps.

  In the example of FIG. 3, since the arrival station of user A and the departure stations of user B and user C are both ST2, use stations overlap. User A's usage time is from 13:30 (use start time) to 14:20 (use end time), and user B's use time is from 14:00 (use start time) to 14:45. The usage time of the user C is from 14:00 to 14:20. Since the use end time of user A is a time later than the use start times of user B and user C, the use time of user A overlaps with the use time of user B and user C.

  When the return station of the previously used vehicle is set as the departure station of the next used vehicle, such as the overlap relationship between the user A and the user B or the overlap relationship between the user A and the user C Can increase the operating rate of the vehicle by using the same vehicle. However, since the usage time of the user A overlaps with the usage times of the users B and C, the vehicle cannot be used efficiently at the user-specified time.

  The reservation management unit 11 confirms the width of the use start time of the user B, and changes the use start time of the user B within the range of the use start time of the user B, so that the user B uses the shared vehicle 200. Determine if you can. The reservation management unit 11 also determines whether or not the user C can use the shared vehicle 200 by changing the use start time of the user C within the range of the use start time of the user C. Determine.

  In the example of FIGS. 3 and 4, the user B designates the width of the use start time of 15 minutes, and the user C designates the width of the use start time of 20 minutes. User B's use start time can be changed from 14:00 to 14:15, and user C's use start time can be changed from 14:00 to 14:20. That is, the use start time of the user B and the use start time of the user C can be changed after the use end time (14:15) of the user A. Therefore, the reservation management unit 11 determines that the user B and the user C can use the vehicle by changing the use start time. In the present embodiment, when the user A's use end time is the same as the user B's use start time after the change, the user B determines that the vehicle can be used. When the margin time (for example, 5 minutes) cannot be secured, it may be determined that the use is not possible. Further, for example, even when the use start time of the user B or the user C is changed within the range of the use start time, the reservation management is performed when the use start time after the change is not later than the use end time of the user A. The part 11 determines that it cannot be used.

  When it is assumed that a vehicle is lent from ST2 to user B and user C, only the vehicle returned by user A is actually parked at ST2. Therefore, it is necessary to assign a vehicle to either user B or user C. In such a case, the reservation management unit 11 allows the shared vehicle 200 to be used by either the user B or the user C so that other users can use the return vehicle after the use of the users B and C. Determine whether or not to lend.

  In the example of FIGS. 3 and 4, the use reservation of the shared vehicle 200 is not entered from another user at the arrival station (ST3) of the user B. On the other hand, in user C's arrival station (ST4), user D makes a reservation for using shared vehicle 200. Therefore, in order to increase the number of users who use the shared vehicle 200, the reservation management unit 11 determines that the user C can use the vehicle, and determines that the user B cannot use the vehicle.

  The time when user C returns the vehicle to ST4 (use end time) is 14:40. The time specified by the user D to use the vehicle from ST4 (use start time) is 14:30. Since the use start time of the user C is the time after the change, the allowable time length for changing the use start time is short. User D designates the width of the use start time of 15 minutes. Therefore, as shown in FIG. 4, if the use start time of the user D is changed from 14:30 to 14:45, the user D can use the return vehicle of the user C in ST4. The reservation management unit 11 determines that the user D's vehicle can be used by changing the use start time of the user D.

  As described above, in the state before changing the usage start time of each user within the range of the usage change time width, the number of users who can use the shared vehicle is one (user A only). In addition, when the rental vehicles are assigned to the users A to D in the order of application for use reservation, the number of users who can use the shared vehicle 200 is one (only the user A). On the other hand, as in the present embodiment, the use start time of each user is changed within the range of the use change time range, and the combination of users permitted to be used is set as user A, user C, and user D. The number of users who can use is 3.

  Thereby, the reservation management unit 11 determines whether or not the use station and the use time overlap among a plurality of users, and when it is determined that the use overlaps, the number of users using the vehicle is maximized. The use start time is changed within the range of the use start time, and the combination that maximizes the number of users is calculated. The reservation management unit 11 permits the use of the user A and notifies the user A that the reservation is confirmed. At this time, when the use start time is changed, the reservation management unit 11 notifies the changed use start time. In the example of FIGS. 3 and 4, the user B cannot use the user B when the use permission of the user A is determined. Therefore, the reservation management unit 11 cannot make a reservation to the user B. May be notified. In addition, the reservation management unit 11 may notify the users C and D of the changed use start time. The reservation management unit 11 performs the same determination as described above when the use permission of the user C is determined, i.e., 30 minutes before the use start time of the user C.

  The reservation management function by the reservation management unit 11 will be described after giving other specific examples. In another specific example, as shown in FIG. 5, three users have already applied for a use reservation as a pre-reservation. Further, it is assumed that the application for use reservation is made in the order of the user E, the user F, and the user G. The use start time, use start time range (changeable time), scheduled use time length, departure station, and arrival station of the three users are as shown in the table of FIG. For ease of explanation, it is assumed that there is only one parking space provided in ST2, and this parking space is vacant. In ST1 and ST3, an available shared vehicle 200 is parked.

  The reservation management unit 11 determines that the current time has reached the use determination time when the time is 30 minutes before the use start times of the users E and F, that is, at 14:00. The reservation management unit 11 determines whether the use station and the use time overlap between users in order to determine the use reservation of the users E and F.

  In the example of FIG. 5, since the arrival station of user E, the arrival station of user F, and the departure station of user F are all ST2, use stations overlap. User E, user F, and user G use time also overlaps.

  After the shared vehicle 200 is returned to ST2 by the user E or the user F, the use reservation of the user G is on standby. Therefore, if the user G can use the return vehicle of the user E or the user F, the number of users who can use the vehicle increases.

  There is one empty parking space for ST2. Since the use start time of the user G is 15:00 and the width of the use start time of the user G is 0 minutes, the use time of the user G cannot be changed from 15:00.

  The reservation management unit 11 confirms the width of the use start time of the users E and F, and changes the use start time of the user B within the range of the use start time of the user B, so that the user G can use the shared vehicle 200. It is determined whether or not can be used.

  In the example of FIG. 5, the user E designates the width of the use start time of 5 minutes, so the use start time of the user E can be changed from 14:30 to 14:25. Then, the shortest use end time of the user E is 15:05 (= 14: 25 + 40 minutes). Since the user F designates the width of the 15 minutes use start time, the user F use start time can be changed from 14:30 to 14:15. Then, the shortest use end time of the user F is 14:55 (= 14: 15 + 40 minutes). That is, even if the user E changes the use start time within the range of the use start time, the user E cannot return the shared vehicle 200 by the use start time of the user G. On the other hand, the user F can return the shared vehicle 200 by the use start time of the user G by changing the use start time within the range of the use start time. Therefore, the reservation management unit 11 determines that the user F and the user G can use the vehicle by changing the use start time, and determines that the user E cannot use the vehicle.

  As described above, in a state before changing the use start time of each user within the range of the use change time width, the number of users who can use the shared vehicle is one (user E or F only). When the rental vehicles are assigned to the user E and the user F in the order of application for use reservation, the number of users who can use the shared vehicle 200 is one (only the user E). On the other hand, the shared vehicle can be used by changing the use start time of each user within the range of the use change time range and setting the combination of users permitted to use as the user F and the user G as in the present embodiment. The number of users is two.

  Thereby, the reservation management unit 11 determines whether or not the use station and the use time overlap among a plurality of users, and when it is determined that the use overlaps, the number of users using the vehicle is maximized. The use start time is changed within the range of the use start time, and the combination that maximizes the number of users is calculated. The reservation management unit 11 permits the use of the users F and G, and notifies the users F and G that the reservation has been confirmed. At this time, the reservation management unit 11 notifies the user F that the use start time has been changed. In addition, the reservation management unit 11 notifies the user E that the reservation is impossible.

  Next, a control flow of reservation management control by the reservation management unit 11 will be described. FIG. 6 is a flowchart for explaining the control flow of the reservation management unit 11.

  In step S <b> 1, the reservation management unit 11 determines whether or not a use reservation for the shared vehicle 200 is received from the user. When the use reservation is accepted, the reservation management unit 11 executes the control flow after step S2. The reservation management unit 11 executes the control flow of step S4 when the use reservation is not accepted. In step S2, the reservation management unit 11 sets a departure station and an arrival station based on the information indicated by the accepted use reservation. When the station is designated by the user, the reservation management unit 11 selects a use station (departure station and arrival station) as the station designated by the user. If the designation from the user is a specific location such as a facility, the reservation management unit 11 selects the nearest station at the designated location as the use station.

  In step S <b> 3, the reservation management unit 11 stores use reservation information in the database 130. The usage reservation information includes usage time information designated by the user and selected usage station information.

  In step S4, the reservation management unit 11 determines whether or not the current time has reached the usage determination time. If the usage determination time has not been reached, the reservation management unit 11 ends the control flow. When the use determination time is reached, the reservation management unit 11 executes the control flow after step S5.

  In step S <b> 5, the reservation management unit 11 determines whether or not usage conditions overlap among a plurality of users. The use conditions correspond to use time conditions and use station conditions.

  If the usage time and the usage station overlap among a plurality of users, in step S6, the reservation management unit 11 calculates a combination that maximizes the number of users who can use the vehicle. In step S7, the reservation management unit 11 transmits confirmed reservation information to the user whose reservation is confirmed. The confirmed reservation information includes information on the confirmed use time and information on the confirmed use station.

  In the control flow of step S5, when at least one of the usage time and the usage station does not overlap among a plurality of users, the reservation management unit 11 executes the control flow of step S7.

  The reservation management unit 11 ends the control flow after executing the control flow of step S7.

  As described above, in the present embodiment, a station that lends or returns the shared vehicle 200 is selected as a use station based on the use request received from the user, and the use station and the use time of the vehicle overlap among a plurality of users. If it is determined whether or not to overlap, the use start time is changed within the changeable time range so that the number of users using the vehicle is maximized. Thereby, the number of users who can use the shared vehicle 200 can be increased. As a result, the operating rate of the shared vehicle 200 can be increased.

  Further, in the present embodiment, usage requests are received from user B who desires a rental station (departure station: ST2) as a rental site and user C who desires the same rental station (departure station: ST2) as a rental site. When the use time of the shared vehicle 200 overlaps between the user B and the user C and the shared vehicle 200 to be used overlaps, the shared vehicle 200 after the user B or the user C returns to the return station. Change the use start time so that it can be used by other users D, and allow user C of user B or user C whose use start time is changed to use the vehicle. Thereby, when utilization is permitted with respect to any user among the overlapping users, other users can use the return vehicle. Therefore, the number of users who can use the shared vehicle 200 can be increased.

  In this embodiment, user A who wants the return station (arrival station: ST2) as the return place, user B who wants the same station (ST2) as the rent place, and user who wants the same station (ST2) as the rent place. From C, each user's usage request is accepted. When the use time of the shared vehicle 200 overlaps between the user A and the user B and between the user A and the user C, the use end time of the user A and the use start time after the change of the user B And the use start time after the change of the user C is compared, and the use of the shared vehicle 200 is permitted to the user whose use start time after the change is after the use end time of the user A. Thereby, when utilization is permitted with respect to any user among the overlapping users, other users can use the return vehicle. Therefore, the number of users who can use the shared vehicle 200 can be increased.

  In this embodiment, the user E who wants the return station (arrival station: ST2) as the return place, the user F who wants the same station (ST2) as the return place, and the user who wants the same station (ST2) as the rental place. From G, each user's usage request is accepted. When the use time of the shared vehicle 200 overlaps between the user E and the user G and between the user F and the user G, the use end time after the change of the shared vehicle 200 by the user E, the user F The use end time after the change and the use start time of the user G are compared, and use of the shared vehicle 200 is permitted to the user F whose use end time after the change is before the use end time of the user G. Thereby, when utilization is permitted with respect to any user among the overlapping users, other users can use the return vehicle. Therefore, the number of users who can use the shared vehicle 200 can be increased.

  In this embodiment, the user can input the changeable range of the use start time. However, the present invention is not limited to the use start time, and the changeable range of the use end time may be input.

<< Second Embodiment >>
A car sharing system according to another embodiment of the present invention will be described. In this embodiment, the control in the case where there are a plurality of combinations with the maximum number of users is different from the other embodiments. Since other controls and specific configurations are the same as those of the first embodiment, this embodiment appropriately incorporates the description of the first embodiment.

  When there are a plurality of combinations with the maximum number of users, the reservation management unit 11 according to the present embodiment gives priority to a user with a long available time width among a plurality of users with overlapping use times and use stations. The use of the shared vehicle 200 is permitted.

  Hereinafter, a specific example will be described. In a specific example, three users are already pre-reserved and have applied for use reservations. Further, it is assumed that the application for use reservation is made in the order of user A, user B, and user C. The use start time, use start time range (changeable time), scheduled use time length, departure station, and arrival station of the three users are as shown in the table of FIG. In addition, among the users A to C, the combination including only the user A, the combination including only the user B, and the combination including only the user C are combinations having the maximum number of users, and the number of users in each combination is the same. To do. FIG. 8 is a conceptual diagram showing the use station relationship for each of the users A to D. For ease of explanation, it is assumed that each station has only one parking space.

  As shown in FIG. 8, among the three departure stations (ST1, ST2, and ST3), the shared vehicle 200 is parked only at ST2. Of the three departure stations (ST4, ST5, and ST6), the empty parking space is only ST5. Therefore, the departure station and the arrival station are ST2 and ST5, respectively.

  And as shown in FIG. 7, use time and a use station overlap between users AC. When the usage time and the usage station are duplicated among a plurality of users and the number of users determined by the combination is the same regardless of which user is selected, the reservation management unit 11 selects each of the users specified by the plurality of users. Among the available time widths, the use of the vehicle is permitted to a user who has designated a time having the longest available time width. In the example of FIG. 7, since the usable time width of the user C is longer than that of the user A and the user B, the reservation management unit 11 permits the use of the shared vehicle 200 by the user C and is shared by the user A and the user B. The use of the vehicle 200 is not permitted. The reservation management unit 11 notifies the user C that the reservation is confirmed, and notifies the user B and the user A that the reservation is impossible.

  In the specific examples of FIGS. 7 and 8, an example in which a reservation of one user among a plurality of users is confirmed is shown. However, when reservations of a plurality of users can be confirmed, the reservation management unit 11 Among the available time widths specified by the user, the user who has specified a longer available time width is given priority to allow the use of the vehicle. For example, when the usage relationship between the users A to C and the overlapping relationship between the usage stations is as shown in the table of FIG. 7 and the reservations for the two users can be confirmed, the reservation management unit 11 determines that the users B and C The use of the shared vehicle 200 by the user A is permitted, and the use of the shared vehicle 200 by the user A is not permitted.

  Next, a control flow of reservation management control by the reservation management unit 11 will be described. FIG. 9 is a flowchart for explaining the control flow of the reservation management unit 11. Since the control flow of steps S11 to 16 is the same as the control flow of steps S1 to S6 according to the first embodiment, a description thereof will be omitted. Since the control flow of step S19 is the same as the control flow of step S7 according to the first embodiment, a description thereof will be omitted.

  After the control flow in step S16, in step S17, the reservation management unit 11 determines whether there are a plurality of combinations. If there are not a plurality of combinations, the reservation management unit 11 ends the control flow after executing the control flow in step S19.

  When there are a plurality of combinations, in step S18, the reservation management unit 11 allows the use of the shared vehicle 200 by giving priority to a user having a long use start time among users corresponding to the plurality of combinations. .

  As described above, in the present embodiment, when it is determined that the usage time of the usage station and the shared vehicle 200 overlaps among a plurality of users, among the plurality of overlapping users, the user whose use start time is long Priority is given to the use of the shared vehicle 200. Thereby, since the range in which the usage time can be adjusted is widened, it becomes easier to accept usage reservations from other users, so that the operating rate of the vehicle can be increased.

<< Third Embodiment >>
A car sharing system according to another embodiment of the present invention will be described. In this embodiment, the control in the case where there are a plurality of combinations with the maximum number of users is different from the other embodiments. Since other controls and specific configurations are the same as those of the first embodiment, this embodiment appropriately incorporates the description of the first embodiment.

  When there are a plurality of combinations with the maximum number of users, the reservation management unit 11 according to the present embodiment gives priority to a user with a short usage time among a plurality of users with overlapping usage times and usage stations, and shares them. The use of the vehicle 200 is permitted.

  Hereinafter, a specific example will be described. The conditions of the specific example are the same as the specific example shown in the second embodiment.

  As shown in FIG. 7, the usage time and the usage station overlap among users A to C. That is, when the use time and use station overlap among a plurality of users and the number of users determined by the combination is the same regardless of which user is selected, the reservation management unit 11 is designated by the plurality of users. In addition, use of the vehicle is permitted to a user who designates a time with the shortest use time in each available time width. In the example of FIG. 7, since the scheduled use time length of the user B is shorter than that of the user A and the user C, the reservation management unit 11 permits the use of the shared vehicle 200 by the user B, and the shared vehicle by the user A and the user C. 200 is not allowed. The reservation management unit 11 notifies the user B that the reservation is confirmed, and notifies the user A and the user C that the reservation is impossible.

  In the specific example, an example is shown in which a reservation of one user among a plurality of users is confirmed. However, when a reservation of a plurality of users can be confirmed, the reservation management unit 11 is designated by a plurality of users. A user who specifies a shorter usage time out of the scheduled usage time length is given priority, and the use of the vehicle is permitted. For example, when the usage relationship between the users A to C and the overlapping relationship between the usage stations is as shown in the table of FIG. 7 and the reservations for the two users can be confirmed, the reservation management unit 11 determines that the users A and B The use of the shared vehicle 200 by the user C is permitted, and the use of the shared vehicle 200 by the user C is not permitted.

  Next, a control flow of reservation management control by the reservation management unit 11 will be described. FIG. 10 is a flowchart for explaining the control flow of the reservation management unit 11. Since the control flow of steps S21 to S26 is the same as the control flow of steps S1 to S6 according to the first embodiment, a description thereof will be omitted. Since the control flow of step S29 is the same as the control flow of step S7 according to the first embodiment, a description thereof will be omitted.

  After the control flow in step S26, in step S27, the reservation management unit 11 determines whether there are a plurality of combinations. If there are not a plurality of combinations, the reservation management unit 11 ends the control flow after executing the control flow in step S29.

  When there are a plurality of combinations, in step S28, the reservation management unit 11 allows the use of the shared vehicle 200 with priority given to a user with a short usage time among users corresponding to the plurality of combinations.

  As described above, in the present embodiment, when it is determined that the usage time of the usage station and the shared vehicle 200 overlaps among a plurality of users, priority is given to a user having a short usage time among a plurality of overlapping users. The use of the shared vehicle 200 is permitted. Thereby, since the frequency | count of utilization of a vehicle increases, the operation rate of a vehicle can be raised.

<< 4th Embodiment >>
A car sharing system according to another embodiment of the present invention will be described. In this embodiment, the control in the case where there are a plurality of combinations with the maximum number of users is different from the other embodiments. Since other controls and specific configurations are the same as those of the first embodiment, this embodiment appropriately incorporates the description of the first embodiment.

  When there are a plurality of combinations with the maximum number of users, the reservation management unit 11 according to the present embodiment gives priority to a user with a long available time width among a plurality of users with overlapping use times and use stations. The use of the shared vehicle 200 is permitted.

  Hereinafter, a specific example will be described. In a specific example, four users are already pre-reserved and have applied for use reservations. Further, it is assumed that the application for use reservation is made in the order of user A, user B, user C, and user D. The use start time, use start time range (changeable time), scheduled use time length, departure station, and arrival station of the four users are as shown in the table of FIG. The usage conditions and the like of the users A to C are the same as the specific example shown in the second embodiment. In addition, among the users A to C, the combination including only the user A, the combination including only the user B, and the combination including only the user C are combinations having the maximum number of users, and the number of users in each combination is the same. To do. Further, the states of the three departure stations (ST1, ST2, and ST3) and the states of the three arrival stations (ST4, ST5, and ST6) are the same as the specific example shown in the second embodiment. For ease of explanation, it is assumed that each station has only one parking space.

  The usage time and the usage station overlap among the users A to C. When the usage time and the usage station are duplicated among a plurality of users and the number of users determined by the combination is the same regardless of which user is selected, the reservation management unit 11 selects each of the users specified by the plurality of users. The user is permitted to use the vehicle with the earliest use end time in the available time range. In a specific example, the user A and user B use end time is earlier for the user C. The reservation management unit 11 permits the user A or the user B to use the shared vehicle 200 and does not allow the user C to use the shared vehicle 200. When selecting one of the user A and the user B, for example, a reservation application order or a longer one of the use start times as in the second embodiment may be given priority. Then, the reservation management unit 11 notifies the user A or the user B that the reservation is confirmed, and notifies the user C that the reservation is impossible.

  In the specific example of FIG. 11, the user D has applied for a reservation at the use start time (14:30) with the departure station as ST5. In the present embodiment, the use of the shared vehicle 200 is permitted to the user A or the user B whose use end time is earlier in order to advance the return time of the vehicle to ST5. Thereby, since the user D can use the return vehicle to ST5, the operation rate of the vehicle increases.

  In the specific example of FIG. 11, an example in which a reservation of one user among a plurality of users is confirmed is shown, but when a reservation of a plurality of users can be confirmed, the reservation management unit 11 Among the use end times, priority is given to the user whose use end time is earlier, and the use of the vehicle is permitted. For example, when the usage time of users A to C and the overlapping relationship of the usage stations are as shown in the table of FIG. 11 and there are two empty parking spaces in ST5, it is possible to confirm the reservations for two users. The reservation management unit 11 permits the use of the shared vehicle 200 by the users A and B and does not allow the use of the shared vehicle 200 by the user C.

  Next, a control flow of reservation management control by the reservation management unit 11 will be described. FIG. 12 is a flowchart for explaining the control flow of the reservation management unit 11. Since the control flow of steps S31 to 36 is the same as the control flow of steps S1 to S6 according to the first embodiment, the description thereof is omitted. Since the control flow of step S39 is the same as the control flow of step S7 according to the first embodiment, a description thereof will be omitted.

  After the control flow in step S36, in step S37, the reservation management unit 11 determines whether there are a plurality of combinations. If there are not a plurality of combinations, the reservation manager 11 ends the control flow after executing the control flow in step S39.

  When there are a plurality of combinations, in step S38, the reservation management unit 11 allows the use of the shared vehicle 200 by giving priority to a user whose use end time is early among users corresponding to the plurality of combinations.

  As described above, in the present embodiment, when it is determined that the usage time of the usage station and the shared vehicle 200 overlaps among a plurality of users, priority is given to the user whose usage end time is early among the plurality of overlapping users. Let the shared vehicle 200 be used. Thereby, the opportunity which makes another user utilize a return vehicle can be increased, and the operation rate of a vehicle can be raised.

<< 5th Embodiment >>
