Description

The present invention relates to a vehicle dispatch reservation management system, a vehicle dispatch system, a vehicle dispatch reservation data management device, and a vehicle dispatch reservation data management program.

Patent Document 1 proposes an on-demand shared vehicle operation management device that is equipped with an operation management means that determines an operation plan for an on-demand shared vehicle in response to requests from multiple users and manages the operation of the on-demand shared vehicle in accordance with the determined operation plan. This on-demand shared vehicle operation management device determines an operation plan so that multiple users can use a single on-demand shared vehicle.

Patent Document 1 also proposes that if a user wishes to change the reservation details for use of an on-demand shared vehicle (such as the planned boarding and disembarking locations and times), the operation plan be adjusted to take these changes into account.

International Publication No. 2014-045359

However, in Patent Document 1, when multiple users use one on-demand shared vehicle, there is no specific consideration of the impact of a change in the reservation details of one user on the dispatch of other users. In particular, if a previous user changes the boarding and alighting location and boarding and alighting time for an on-demand shared vehicle, depending on the changes, there is a possibility that dispatch to users who have made reservations to use the on-demand shared vehicle after the previous user has completed their use may be delayed.

In light of these circumstances, the object of the present invention is to realize a system that, when multiple users have made reservations for a single shared vehicle, can determine the scope of changes to the reservation details of the first user while minimizing delays in dispatching the vehicle to subsequent users.

According to an aspect of the present invention, a vehicle dispatch reservation management system is provided, which includes a user terminal owned by each of a plurality of users who use a shared vehicle, and a server connected to the user terminal so as to be able to communicate with the user terminal. In this vehicle dispatch reservation management system, the server includes a storage unit that stores reservation data indicating reservation contents related to a vehicle dispatch process for each of a plurality of users in association with identification information of each user terminal, a specification unit that refers to the storage unit and specifies, for one shared vehicle, first reservation data associated with a first user terminal and second reservation data related to a second vehicle dispatch process to be executed after the first vehicle dispatch process defined by the first reservation data, a changeable range calculation unit that calculates a changeable range of the reservation contents related to the first vehicle dispatch process based on the specified first reservation data and second reservation data, and a transmission unit that transmits the calculated changeable range to the first user terminal. The changeable range calculation unit calculates the changeable range so that the shared vehicle arrives at the planned boarding location related to the second vehicle dispatch process before the planned boarding time related to the second vehicle dispatch process. Furthermore, the first user terminal includes a display unit that displays the changeable range received from the server. The first reservation data specifies a planned boarding time, a planned boarding location, a planned disembarking time, and a planned disembarking location of a first user who is provided with the first vehicle dispatching process. The changeable range calculation unit sets a changed location that is a planned boarding location or a planned disembarking location of the first vehicle dispatching process after the change assuming a change in the planned boarding time, the planned boarding location, the planned disembarking time, or the planned disembarking location of the first user, calculates a first traveling time as a traveling time of the shared vehicle from the changed location to a next fixed location that is the next fixed location that is not changed, calculates a next fixed location arrival predicted time as the arrival predicted time of the shared vehicle at the next fixed location by adding the first traveling time to the arrival predicted time of the shared vehicle at the changed location, and calculates the changeable range such that the next fixed location arrival predicted time is earlier than a predetermined allowable arrival time.

According to the present invention, in a situation where multiple users have made reservations for a single shared vehicle, a specific system is realized that allows one user to change the reservation details while minimizing delays in dispatching vehicles to other users.

[First embodiment]
Fig. 1 is a diagram for explaining the configuration of a vehicle dispatch system 10 according to this embodiment. Fig. 2 is a diagram for explaining the configuration of a vehicle dispatch reservation management system 15 and a user terminal UT, which are components of the vehicle dispatch system 10. Fig. 3 is a diagram for explaining the configuration of an in-vehicle terminal VT, which is a component of the vehicle dispatch system 10.

The vehicle dispatch system 10 is a system for providing a vehicle dispatch service using a shared vehicle V to each user U according to reservation details regarding the use of the shared vehicle V specified by multiple users U.

As shown in FIG. 1, the vehicle dispatch system 10 of this embodiment includes a vehicle dispatch reservation management system 15 and an in-vehicle terminal VT communicatively connected to the vehicle dispatch reservation management system 15 via a network 100. Furthermore, as shown in FIG. 2, the vehicle dispatch reservation management system 15 includes user terminals UT (UTVa, UT2, . . . UTn) operated by users U (U1, U2, . . . Un) who use a shared vehicle V, and a server 20 communicatively connected to each user terminal UT and the in-vehicle terminal VT via the network 100.

The server 20, user terminal UT, and in-vehicle terminal VT that make up the vehicle dispatch system 10 are each composed of a computer equipped with an arithmetic/control device such as a CPU (Central Processing Unit), various storage devices such as a RAM (Random Access Memory), a ROM (Read Only Memory), an SSD (Solid State Drive), or a hard disk (magnetic storage device), and various input/output devices such as a keyboard, a mouse, a touch panel, a display, a printer, and an I/O port. The server 20, user terminal UT, and in-vehicle terminal VT execute the various processes described below using the above hardware and a specific program (software) stored in the storage device.

The network 100 is also configured with various hardware and communication protocols to enable intercommunication between each user terminal UT, the in-vehicle terminal VT, and the server 20. In particular, the communication function between the in-vehicle terminal VT and the server 20 in the network 100 is realized by V2N (Vehicle to Network) using a wide area communication interface installed in the shared vehicle V.

The vehicle dispatch reservation management system 15 of this embodiment is configured as a system for managing reservation data Bd _u indicating reservation contents corresponding to each of the vehicle dispatch processes for multiple users U (U1, U2, ... Un). In particular, the management of the reservation data Bd _u of this embodiment includes, when providing a vehicle dispatch service to multiple users U for one shared vehicle V, the generation of the reservation data Bd _{u based on the reservation contents corresponding to the location (scheduled boarding and disembarking place, etc.) and schedule (scheduled boarding and disembarking point, etc.) in the vehicle dispatch process executed for each user U} , the generation of the change range of the reservation contents, and the update.

In this specification, the term "vehicle dispatch processing for each user U" is defined as processing related to the provision of vehicle dispatch services to multiple users U. More specifically, the vehicle dispatch processing refers to a series of processes from the time when a user U using a shared vehicle V starts boarding the shared vehicle V at the planned boarding location to the time when the user U completes disembarking at the planned disembarking location. The boarding operation includes, in addition to the user U's own actions for boarding the shared vehicle V, the action of placing baggage on the shared vehicle V, actions expected in bad weather (such as closing an umbrella), and processing associated with boarding the shared vehicle V, such as the action of notifying the user U of information required to be notified (such as voice guidance) such as how to use the shared vehicle V. Furthermore, the disembarking operation includes, in addition to the user U's own actions for disembarking from the shared vehicle V, the action of unloading baggage from the shared vehicle V, actions expected in bad weather (such as opening an umbrella), and processing associated with disembarking from the shared vehicle V, such as the action of notifying the user U of necessary information.

In the following, the scheduled time when the provision of the vehicle dispatch process to user U will begin (the time when user U is scheduled to begin boarding the shared vehicle V) will be referred to as the "scheduled boarding time t _s ". The location where the vehicle dispatch process is scheduled to begin (i.e., the scheduled boarding location) will also be referred to as the "scheduled boarding location p _s ". Furthermore, the time when the vehicle dispatch process for each user U is scheduled to be completed (the time when user U is scheduled to complete disembarking from the shared vehicle V) will be referred to as the "scheduled disembarking time t _e ". The location where the vehicle dispatch process is scheduled to be completed (i.e., the scheduled disembarking location) will also be referred to as the "scheduled disembarking location p _e ".

Next, we will explain the detailed configuration of the server 20 of the vehicle reservation management system 15 and the user terminal UT.

(Configuration of Server 20)
The server 20 is, for example, a computer for server use installed in a facility where a vehicle dispatching service provider is located, or is composed of hardware and software distributed at multiple locations that can communicate with each other via a network 100 such as a so-called cloud.

In particular, as shown in FIG. 2, the server 20 of this embodiment has a reservation management database 22 (hereinafter also referred to as "reservation management DB 22") as a storage unit, an identification unit 26, a changeable range calculation unit 28, a reservation change processing unit 30, and a transmission/reception unit 32 that functions as a transmission unit. Note that these configurations are realized by cooperation between the hardware and software (programs) of the computer that constitutes the server 20.

The reservation management DB 22 stores reservation data Bd _u corresponding to identification information for identifying each user U (especially each user terminal UT) for each predetermined period (e.g., one business day). Note that the identification information for each user U can be any information that can identify the correspondence between each user U and the reservation data Bd _u , such as information for identifying the individual user U, such as the user U's name, address, or contact information, and the ID information of each user terminal UT.

4 is a table showing one aspect of various data stored in the reservation management DB 22. As shown in the figure, the reservation management DB 22 stores a scheduled boarding time _ts , a scheduled boarding place _ps , a scheduled disembarking time te, and a scheduled disembarking place _pe of the vehicle dispatch process as reservation data Bd _u in association with the identification _information of each user terminal UT.

Moreover, the identification information and reservation data Bd _u stored in the reservation management DB 22 are generated based on information designated in advance by each user U via an input interface or the like of each user terminal UT.

For ease of explanation, in the following, with regard to the main processes constituting the management of the reservation data Bd _u in this embodiment, the user terminal UT that transmits and receives data to and from the server 20 will also be referred to as the "first user terminal UT _k "(1≦k<n). Also, the user U linked to the first user terminal UT _k will also be referred to as the "first user U _k ". Furthermore, the vehicle dispatch process executed for the first user U _k will also be referred to as the "first vehicle dispatch process", and the reservation data Bd _u related to the first user U _k will also be referred to as the "first reservation data Bd _uk ".

In addition, the planned boarding time t _s , planned boarding location p _s , planned disembarking time t _e , and planned disembarking location p _e of the first user U _k receiving the first vehicle dispatch processing are also referred to as the "first planned boarding time t _{s_k} ", "first planned boarding location p _{s_k} ", "first scheduled disembarking time t _{e_k} ", and "first planned disembarking location p _{e_k} ", respectively.

On the other hand, the vehicle dispatch process executed after the first vehicle dispatch process defined in the reservation management DB 22 is also referred to as the "second vehicle dispatch process." The user U linked to the second vehicle dispatch process (i.e., the user U who makes a reservation for the shared vehicle V after the first user U _k ) is also referred to as the "second user U _k+1 ," the user terminal UT linked to the "second user U _k+1 " is also referred to as the "second user terminal U _k+1 ," and the reservation data Bd _u related to the second user U _k+1 is also referred to as the "second reservation data Bd _uk+1 ."

Furthermore, the planned boarding time t _s and planned boarding location p _s of the second user U _k+1 who receives the second vehicle dispatch process are also referred to as the "second planned boarding time T2" and the "second planned boarding location P2", respectively.

2, when the identification unit 26 of the server 20 receives the first request signal _Sr1 including the identification information of the first user terminal _UTk and command information requesting presentation of the change range of the reservation contents, the identification unit 26 refers to the reservation management DB 22 and identifies the first reservation data Bd _uk and the second reservation data Bd _uk+1 based on the identification information. The identification unit 26 outputs the identified first reservation data Bd _uk and second reservation data Bd _uk+1 to the changeable range calculation unit 28.

The changeable range calculation unit 28 calculates a changeable range R of the reservation contents related to the first reservation data Bd _uk , based on the first reservation data Bd uk and the second reservation data Bd _{uk +1} input from the identification unit 26.

In particular, the changeable range calculation unit 28 calculates a changeable range R as a range in which at least any one of the first scheduled boarding time t _{s_k} , the first planned boarding location p _{s_k} , the first scheduled disembarking time t e_k , and the first planned disembarking location p e_k included in the first reservation data Bd _uk can be changed under the condition that the shared vehicle V arrives at the second planned boarding location _P2 before the second scheduled boarding time _T2 . In other words, the changeable range R obtained by this calculation logic specifies the change range of the reservation contents of the first reservation data Bd _uk that does not delay the dispatch of the second user U _k+1 (dispatch before the second scheduled boarding time T2). Hereinafter, this calculation logic will be described in more detail.

In particular, in this embodiment, a calculation method for the comprehensive changeable range R is described for a case where the first scheduled boarding time t _{s_k} , the first scheduled boarding location p _{s_k} , the first scheduled disembarking time t _{e_k} , or the first scheduled disembarking location p _{e_k} is changed due to a reservation change in the first vehicle dispatch process.

Fig. 5 is a diagram for explaining the calculation mode of the changeable range R in this embodiment. In Fig. 5, the calculation of the changeable range R due to reservation change of the first user Uk is assumed, assuming a vehicle allocation area A in which vehicle allocation processes are executed for the user _Uk-1 (hereinafter also referred to as "previous user _{Uk -1} ") who receives the vehicle allocation process (hereinafter also referred to as "previous user vehicle allocation process") set immediately before the first vehicle allocation process in the reservation management DB 22, the first user _Uk , and the second user _Uk+1 .

As shown in FIG. 5, in the calculation of the changeable range R in this embodiment, a "first fixed location G1", a "changed location Va", and a "second fixed location G2" are specified within the vehicle allocation area A. Here, the "first fixed location G1" is a stop of the shared vehicle V immediately before the changed location Va, and is a location that is not affected by the reservation change in the first vehicle allocation process. As the first fixed location G1, the planned drop-off location p _e of the previous user U _k-1 (hereinafter also referred to as the "previous user's planned drop-off location P0") that is not affected by the reservation change in the first vehicle allocation process, or the first planned boarding location p _{s_k} in the case where it is not changed is assumed.

Furthermore, the "changed location Va" is a stop of the shared vehicle V that is changed in accordance with a reservation change in the first vehicle dispatch process. The changed location Va is assumed to be the first planned boarding location p _{s_k} or the first planned disembarking location p _{e_k} that is changed in accordance with a reservation change in the first vehicle dispatch process. Furthermore, the concept of this "changed location Va" may also include a case in which only the first planned boarding time t _{s_k} or the first planned disembarking time t _{e_k} is changed due to a reservation change in the first vehicle dispatch process (a case in which the first planned boarding location p _{s_k} and the first planned disembarking location p _{e_k} do not substantially change).

The "second fixed location G2" is a stop of the shared vehicle V immediately after the changed location Va and is a location that is not affected by the reservation change in the first vehicle dispatch process. The second fixed location G2 is assumed to be the second planned boarding location P2 that is not affected by the reservation change in the first vehicle dispatch process, or the first planned disembarking location p _{e_k} in the case where there is no change.

Then, the changeable range calculation unit 28 calculates the changeable range R using the following formula (1) based on the model of the dispatch area A shown in Figure 5.

Here, "T _G1 " in equation (1) is the scheduled time when the shared vehicle V arrives at the first fixed location G1. Note that, hereinafter, this time is also simply referred to as the "scheduled first fixed location arrival time T _G1 ". The scheduled first fixed location arrival time T _G1 is a constant that does not change, for example, depending on a reservation change in the first vehicle allocation process recorded in the reservation management DB 22. Also, "t _Va " represents the time when the shared vehicle V is predicted to arrive at the changed location Va. Note that, hereinafter, this time is also simply referred to as the "predicted changed location arrival time t _Va ". The predicted changed location arrival time t _Va is a variable that can change depending on a reservation change in the first vehicle allocation process.

Furthermore, "Δt0" represents the predicted travel time of the shared vehicle V from the first fixed location G1 to the changed location Va. In the following, this travel time is also simply referred to as the "0th travel time Δt0." And, "Δt1" represents the predicted travel time of the shared vehicle V from the changed location Va to the second fixed location G2. In the following, this travel time is also simply referred to as the "first travel time Δt1."

In particular, the changeable range calculation unit 28 refers to map data stored in an external server or in any memory area of the shared vehicle V, and information on road conditions in the dispatch area A in which the shared vehicle V travels when providing the dispatch service, to identify the location information (such as GPS coordinates) of the first fixed location G1, the change location Va, and the second fixed location G2, and calculates the 0th driving time Δt0 and the first driving time Δt1 based on the location information.

And, "Tb" represents the latest allowable time for the shared vehicle V to be predicted to arrive at the second fixed location G2 (hereinafter also simply referred to as "second fixed location predicted arrival time t _G2 "). Hereinafter, this will also be simply referred to as the "allowable arrival time Tb." Note that the allowable arrival time Tb is appropriately determined from the viewpoint of having the shared vehicle V arrive at the second planned boarding location P2 before the second planned boarding time T2. Also, the second fixed location predicted arrival time t _G2 can be calculated as the time obtained by adding the zeroth running time Δt0 and the first running time Δt1 to the first fixed location predicted arrival time T _G1 .

The calculation algorithm defined by formula (1) makes it possible to calculate the changeable range R that can suppress delays in dispatching vehicles to the second user U _k+1 . Furthermore, by repeatedly applying the calculation of the changeable range R using formula (1) to successive dispatch processes stored in the reservation management DB 22 on a business day basis or the like, it is possible to realize the calculation of a suitable changeable range R for each user U.

Then, the changeable range calculation unit 28 outputs the calculated changeable range R to the reservation change processing unit 30 and the transmission/reception unit 32.

The reservation change processing unit 30 receives the second request signal Sr2 including the identification information of the first user terminal _{UTk ,} a command to change the reservation contents related to the first reservation data _Bduk , and information on the reservation contents to be changed (after the change). The reservation change processing unit 30 then determines whether the reservation contents after the change are included in the changeable range R by the changeable range calculation unit 28.

In particular, the reservation change processor 30 specifies the changes required for at least one of the first scheduled boarding time _{ts_k} , the first planned boarding location _{ps_k} , the first scheduled disembarking time _{te_k} , and the first planned disembarking location _{pe_k} included in _{the second} request signal Sr2. Then, the reservation change processor 30 determines whether or not the changes satisfy the change permission condition defined in formula (1).

If the determination result is positive, the reservation change processing unit 30 updates the first reservation data Bd _{uk stored in the reservation management DB 22 to the requested changes. In this case, a change permission signal including information that the change has been permitted is generated and output to the transmission/reception unit 32. In the following, the first reservation data Bd uk updated} in the reservation management DB 22 is also referred to as "updated first reservation data Bd _{uk_up} ".

On the other hand, if the above judgment result is negative, the reservation change processing unit 30 does not reflect the above change content, and maintains the first reservation data Bd _uk in the reservation management DB 22 as it was. In this case, a configuration may be adopted in which a change disapproval signal including information to the effect that the change is not permitted is generated and transmitted to the first user terminal UT _k via the transmission/reception unit 32.

In addition, in the first user terminal UT _k , a configuration may be adopted in which, upon receipt of the change permission signal or the change disallowance signal, the display processing unit 52 executes a predetermined display on the display 54 to notify whether the change to the reservation contents is allowed or not allowed.

The transmitting/receiving unit 32 receives a first request signal _Sr1 from the first request generation unit 50 of the first user terminal UT _k and outputs it to the identification unit 26. Also, it receives a second request signal _Sr2 from the second request generation unit 56 of the first user terminal UT _k and outputs it to the identification unit 26. Furthermore, the transmitting/receiving unit 32 receives the changeable range R from the changeable range calculation unit 28 and outputs it to the display processing unit 52 of the first user terminal UT _k . Also, the transmitting/receiving unit 32 transmits the first reservation data Bd _uk (including updated first reservation data Bd _{uk_up} ) stored in the reservation management DB 22 to the in-vehicle terminal VT described later.

(Configuration of user terminal UT)

Next, the configuration of the user terminal UT (particularly the first user terminal UT _k ) will be described with reference to FIG. 2 etc.

The first user terminal UT _k is a terminal operated by the first user U _k , and is composed of a mobile terminal such as a smartphone, tablet terminal, feature phone (Galapagos mobile phone) or PDA, or a personal computer such as a notebook computer (laptop) or desktop computer.

2, the first user terminal UT _k of this embodiment has a first request generating unit 50, a display processing unit 52 and a display 54 constituting a display unit, and a second request generating unit 56 as a change request generating unit. Note that these configurations are realized by cooperation between the hardware and software (program) of a computer constituting the first user terminal UT _k .

The first user terminal UT _k has a first request generation unit 50 , a display processing unit 52 , a display 54 , and a second request generation unit 56 .

The first request generation unit 50 generates the above-mentioned first request signal S _r1 in response to an operation on an input interface (such as a touch panel) of the first user terminal UT _k , and transmits the generated first request signal S _r1 to the server 20.

The display processing unit 52 executes display control for displaying the changeable range R calculated by the server 20 on the display 54 in a predetermined display mode. The calculation function of the display processing unit 52 is realized by a main processing unit (CPU) of the first user terminal UT _k which also performs processes other than display processing, a co-processor (GPU) specialized for executing display processing, or a combination of these.

The display 54 is a display device such as a liquid crystal display or an organic EL display that displays according to the above display mode in response to commands from the display processing unit 52.

On the other hand, the second request generation unit 56 of the first user terminal UT _k generates the above-mentioned second request signal S _r2 in response to an operation on an input interface (such as a touch panel) of the first user terminal _UT k, and transmits the generated second request signal S _r2 to the server 20.

(Configuration of the vehicle-mounted terminal VT)

Next, the configuration of the vehicle-mounted terminal VT will be explained with reference to Figure 3 etc.

The in-vehicle terminal VT of this embodiment controls the driving of the shared vehicle V in the vehicle allocation area A based on the reservation contents specified in the reservation data Bd _u (particularly the first reservation data Bd _uk or the updated first reservation data Bd _{uk_up} ) stored in the reservation management DB22.

The in-vehicle terminal VT is configured with an in-vehicle computer that realizes various functions for use by the user U, such as a so-called car navigation system and various audio functions, and has an interface function that accepts specific input operations by the user U of the shared vehicle V, and an ECU (Electronic Control Unit) or ADAS (Advanced driver-assistance systems) that realizes the function as the driving assistance device described above.

In particular, as shown in FIG. 3, the vehicle-mounted terminal VT includes a driving control unit 60 that controls the driving actuator 70 of the shared vehicle V. The driving control unit 60 is realized by the cooperation of the hardware and software (program) of the computer that constitutes the vehicle-mounted terminal VT.

The driving control unit 60 executes driving control of the shared vehicle V within the vehicle allocation area A based on the reservation data Bd _u received from the server 20.

More specifically, the driving control unit 60 _{appropriately} refers to map data stored in an external server or an arbitrary storage area of the shared vehicle V, and information on road conditions in the vehicle allocation area A through which the shared vehicle V travels when providing the vehicle allocation service, from the reservation data Bd u, to identify information on each planned driving route of the shared vehicle V set within the vehicle allocation area A. Note that a configuration may be adopted in which the server 20 identifies information on each planned driving route in advance and stores it in the reservation management DB 22, and the driving control unit 60 identifies each planned driving route by referring to the reservation management DB 22.

In particular, in this embodiment, when the first reservation data Bd _uk stored in the above-mentioned reservation management DB 22 is updated, the driving control unit 60 identifies information about each planned driving route based on the updated first reservation data Bd _{uk_up} .

The driving control unit 60 operates the driving actuator 70 mounted on the shared vehicle V so that the shared vehicle V drives along each of the specified planned driving routes. The driving actuator 70 is mainly composed of a drive system actuator and a steering system actuator.

In particular, the drive system actuators are composed of, for example, a driving actuator such as an engine or a motor, and a braking actuator such as a hydraulic brake. In addition, the steering system actuators are composed of, for example, an assist motor that controls the steering torque in an electric power steering system.

According to the configuration of the in-vehicle terminal VT, when the first reservation data Bd _uk is updated, the updated first reservation data Bd _{uk_u} is reflected and then the driving control of the shared vehicle V is executed. In other words, in response to a change in the reservation details of the first user U _k , the change can be automatically reflected in the driving control of the shared vehicle V within the vehicle allocation area A.

For reference, FIG. 6 shows a sequence diagram illustrating the main processes and data exchanges between the components of the vehicle dispatch system 10 according to the present embodiment described above.

The following describes each of the configurations provided in the present embodiment described above and the associated effects.

According to this embodiment, a vehicle reservation management system 15 is provided that includes a user terminal UT owned by each of multiple users U who use a shared vehicle V, and a server 20 communicatively connected to the user terminal UT.

The server 20 of this vehicle dispatch reservation management system 15 includes a reservation management DB22 (Figure 3) as a storage unit that stores reservation data Bd _u indicating reservation details (scheduled boarding time t _s , planned boarding location p _s , scheduled disembarking time t _e , and planned disembarking location p _e related to the vehicle dispatch processing) for each of multiple users U (such as the first vehicle dispatch processing and the second vehicle dispatch processing) in correspondence with identification information (terminal ID, etc.) of each user terminal UT.

The server 20 of the vehicle dispatch reservation management system 15 includes an identification unit 26 that identifies, with respect to one shared vehicle V, second reservation data Bd _uk +1 related to a second vehicle dispatch process to be executed next to the first vehicle dispatch process defined by the first reservation data Bd _uk from the first reservation data Bd _{uk linked to the first user terminal UT k by referring to the reservation management DB 22, a changeable range calculation unit 28 that calculates a changeable range R of the reservation content related to the first vehicle dispatch process based on the identified first reservation data Bd uk and the} second reservation data, and a transmission unit (transmission/reception unit 32) that transmits the calculated changeable range R to the first user terminal UT _k . The changeable range calculation unit 28 calculates the changeable range R so that the shared vehicle V arrives at the planned boarding location p _s of the second vehicle dispatch process before the planned boarding time t _s of the second vehicle dispatch process.

Furthermore, the first user terminal UT _k includes a display processing unit 52 and a display 54 as a display unit that displays the changeable range R received from the server 20 .

This realizes a system equipped with a specific control logic that can set the range of changes to the first vehicle dispatch process (i.e., the range of changes to the reservation contents) defined by the first reservation data _{Bd uk linked} to the first user terminal _UT k (first user U k ) so as not to delay the start of the second vehicle dispatch process for the second user U _k+1 that is to be executed next to the first vehicle dispatch process. That is, by using the vehicle dispatch reservation management system 15 of this embodiment, in a scene in which a plurality of users U have made reservations for use of one shared vehicle V on the same business day, it is possible to determine the range of changes to the reservation contents of the first user U _k so as not to affect the provision of the vehicle dispatch service to the second user U _k+1 later (delay in dispatch).

In addition, the changeable range R calculated by the first user terminal UT _k is displayed, so that the first user U _k can recognize the range of changes to the reservation contents that are permissible from the viewpoint of not delaying the subsequent vehicle dispatch service for the second user U _k+1 .

In particular, in this embodiment, the first reservation data Bd _uk specifies the planned boarding time (first planned boarding time t _{s_k} ), planned boarding location (first planned boarding location p _{s_k ), planned disembarking time (first planned disembarking time t e_k )} , and planned disembarking location (first planned disembarking location p _{e_k} ) of the first user U _k related to the first vehicle dispatch process (see FIG. 4 ). In addition, the changeable range calculation unit 28 sets a changed location Va which is the first planned boarding location p _{s_k} or the first planned disembarking location p _{e_k after the change when it is assumed that the first planned boarding time t s_k ,} the first planned boarding location p _{s_k , the first scheduled disembarking time t e_k} , or the first planned disembarking location _{p e_k is} changed.

The changeable range calculation unit 28 also calculates a predicted change location arrival time t _Va as the arrival time of the shared vehicle V at the change location Va, and calculates a first running time Δt1 as the running time of the shared vehicle V from the change location Va to the next fixed location (second fixed location G2) which is the next fixed location that is not changed. Furthermore, the changeable range calculation unit 28 calculates a predicted next fixed location arrival time (predicted second fixed location arrival time t _G2 ) as the predicted arrival time of the shared vehicle V at the second fixed location G2 by adding the first running time Δt1 to the predicted change location arrival time t _Va as the predicted arrival time of the shared vehicle V at the change location Va. Then, the changeable range calculation unit 28 calculates the changeable range R such that the predicted second fixed location arrival time t _G2 is earlier than a predetermined allowable arrival time Tb.

This realizes a specific control logic for more appropriately quantifying the range in which the reservation details of the first user U _k can be changed, under the condition that it does not affect the provision of the vehicle dispatch service to the second user U _k+1 (delay in dispatch).

Moreover, the server 20 of the vehicle dispatch reservation management system 15 according to this embodiment further includes a reservation change processing unit 30. Moreover, the first user terminal UT _k of the vehicle dispatch reservation management system 15 further includes a second request generation unit 56 as a change request generation unit that generates a change request (first request signal S _r1 ) requesting a change of the reservation contents and transmits it to the server 20.

Then, when the reservation change processing unit 30 receives the first request signal _Sr1 from the first user terminal _UTk , it judges whether or not the changed reservation contents are included in the changeable range R. If the judgment result is positive, the reservation change processing unit 30 updates the first reservation data _Bduk stored in the reservation management DB 22 based on the changed reservation contents (updated first reservation data _{Bduk_up} ). On the other hand, if the judgment result is positive, the reservation change processing unit 30 maintains the first reservation data _Bduk .

This makes it possible to realize a system in which, when a request to change the reservation details related to the first vehicle dispatch process is received from the first user U _k , the change to the reservation details is reflected in the reservation management DB 22 only if the change is within a range that does not delay the dispatch of a vehicle to the second user U _{k+1 (} changeable range R).

In addition, according to this embodiment, a vehicle dispatch system 10 is provided that further includes a vehicle dispatch reservation management system 15 and an in-vehicle terminal VT that is communicatively connected to the server 20 and installed in a shared vehicle V.

The vehicle dispatch system includes a driving control unit 60 that executes driving control of the shared vehicle V within the vehicle dispatch area A where the vehicle dispatch process is executed, based on the reservation data Bd _u received from the server 20. When the first reservation data Bd _uk included in the reservation data Bd _u is updated, the driving control unit 60 executes driving control of the shared vehicle V based on the updated first reservation data Bd _{uk_up} as the updated first reservation data Bd _uk .

This makes it possible to realize a function of automatically controlling the driving of the shared vehicle V within the vehicle allocation area A based on information related to the reservation data Bd _u stored in the reservation management DB of the server 20. In particular, the in-vehicle terminal VT controls the driving of the shared vehicle V based on the updated first reservation data Bd _{uk_up} in which changes to the reservation details are actually reflected. Therefore, changes to the reservation details of the first user U _k managed by the server 20 can be automatically reflected in the driving control of the shared vehicle V that drives away from the server 20.

Furthermore, according to this embodiment, a server 20 is provided as a vehicle dispatch reservation data management device that manages reservation data Bd _u indicating reservation details relating to the vehicle dispatch process for each of a plurality of users U who use a shared vehicle V.

The server 20 also includes a reservation management DB22 (Figure 3) as a storage unit that stores reservation data Bd u indicating reservation details (scheduled boarding time t _s , planned boarding location p _s , scheduled disembarking time t _e , and planned disembarking location _{p e} related to the dispatch processing) for each of multiple users U (such as the first dispatch processing and the second dispatch processing) in correspondence with the identification information (user name, etc.) of each user U.

The server 20 also includes an identification unit 26 that identifies, with respect to one shared vehicle V, second reservation data Bd _{uk +1} related to a second vehicle dispatch process to be executed next to the first vehicle dispatch process defined by the first reservation data Bd _uk from the first reservation data Bd uk linked to the first user _{U k} with reference to the reservation management DB 22, and a changeable range calculation unit 28 that calculates a changeable range R of the reservation content related to the first vehicle dispatch process based on the identified first reservation data Bd _uk and second reservation data. The changeable range calculation unit 28 calculates the changeable range R so that the shared vehicle V arrives at the planned boarding location p _s of the second vehicle dispatch process before the planned boarding time t _s of the second vehicle dispatch process.

This makes it possible to realize a vehicle dispatch reservation data management device equipped with specific control logic that can set the range of changes to the first vehicle dispatch process of the first user U _k (i.e., the range of changes to the reservation details) so as not to delay the start of the second vehicle dispatch process for the second user U _k+1, which is to be executed next after the first vehicle dispatch process.

Furthermore, according to this embodiment, a vehicle dispatch reservation data management program is provided that causes a server 20 as a computer to manage reservation data Bd _u indicating reservation contents related to each vehicle dispatch process for multiple users U who use a shared vehicle V.

In particular, the vehicle dispatch reservation data management program of this embodiment causes the server 20 to refer to a reservation management DB 22 as a storage unit that stores reservation data Bd u indicating reservation details (scheduled boarding time t _s , planned boarding location p _s , scheduled disembarking time t _e , and planned disembarking location p _e related to the vehicle dispatch process (such as the first vehicle dispatch process and the second vehicle dispatch process) for each of multiple users _U in association with the identification information (such as a user name) of each user _U. Then, the server 20 causes the server 20 to identify (the identification unit 26) second reservation data Bd _uk +1 related to the second vehicle dispatch process to be executed following the first vehicle dispatch process defined by the first reservation data Bd _uk from the first reservation data Bd uk linked to the first _{user U k} for one shared vehicle V.

Furthermore, the server 20 is caused to calculate a changeable range R of the reservation contents related to the first vehicle dispatch process based on the identified first reservation data Bd _uk and second reservation data. In particular, the vehicle dispatch reservation data management program of this embodiment causes the server 20 to calculate the changeable range R so that the shared vehicle V arrives at the planned boarding location p _s of the second vehicle dispatch process before the planned boarding time t _s of the second vehicle dispatch process (changeable range calculation unit 28).

This realizes a program for causing a computer to execute specific calculations that can set the range of changes to the first vehicle dispatch process for the first user U _k (i.e., the range of changes to the reservation details) so as not to delay the start of the second vehicle dispatch process for the second user U _k+1, which is to be executed next after the first vehicle dispatch process.

The vehicle reservation data management program may be stored in a memory area of the server 20 that mainly executes the processing using the vehicle reservation data management program, or may be stored in a memory area of any computer that can communicate with the server 20 so that the processing can be executed by the server 20. In addition, the storage medium that stores the vehicle reservation data management program is also included within the scope of the matters described in the specification, etc., of this application at the time of filing.

(Modification)
In the modified example, a calculation mode is provided in which the changeable range R is corrected taking into account the stopping processing time at each boarding/alighting point.

Here, "stopping processing time" refers to the stopping time range of the shared vehicle V at each planned boarding/disembarking location that is set based on the time spent by the user U for boarding and disembarking actions, other necessary processing time, and the time during which the shared vehicle V can be stopped.

The stopping processing time is determined appropriately based on, for example, road information in the dispatch area A (information on no-parking areas), the weather, and personal information of user U (whether or not they have luggage, whether or not they have drunk alcohol, average boarding and alighting times in the past, etc.) or statistical information on boarding and alighting times according to the attributes of user U (such as age and whether or not they have a physical disability).

For example, the changeable range calculation unit 28 performs a correction to the predicted arrival time t _Va at the changed location and/or the permissible arrival time Tb by adding or subtracting the stopping processing time as necessary, and then calculates the changeable range R based on the above formula (1). This makes it possible to calculate the changeable range R as a value that matches a more realistic vehicle dispatch operation that takes into account the time required for the user U to get on and off and the loading and unloading of luggage. Also, a configuration may be adopted in which the stopping processing time is reflected in the calculation of the changeable range R by subtracting a correction value equivalent to the stopping processing time from the permissible arrival time Tb in formula (1).

[Second embodiment]
Hereinafter, the second embodiment will be described. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. In this embodiment, the calculation of the changeable range R when the first scheduled boarding time t _{s_k} or the first scheduled disembarking time t _{e_k} is changed will be described.

(Change of first scheduled boarding time _{ts_k} )
FIG. 7 is a diagram for explaining the calculation of the changeable range R when a change to the first scheduled boarding time t _{s_k} is assumed.

As shown in FIG. 7, when the first user U _k wishes to change the planned boarding time (when the first request signal S _r1 includes information requesting a change to the first planned boarding time t _{s_k} ), the changeable range calculation unit 28 sets the first fixed location G1 to the previous user's planned drop-off location P0, the change location Va to the first planned boarding location p _{s_k} , and the second fixed location G2 to the first planned drop-off location p _{e_k} . Note that the previous user's planned drop-off location P0, the first planned boarding location p _{s_k} , and the first planned drop-off location p _{e_k} are not affected by the reservation change, so the 0th travel time Δt0 and the first travel time Δt1 can be regarded as fixed values m0 and m1, respectively. Therefore, the changeable range calculation unit 28 can calculate the changeable range R based on the following formula (2) in which the first planned boarding time t _{s_k} is a variable, by reflecting the conditions specified in the scene shown in FIG. 7 in formula (1).

(Change in first scheduled alighting time t _{e_k} )
FIG. 8 is a diagram for explaining the calculation of the changeable range R when a change to the first scheduled alighting time t _{e_k} is assumed.

8, when the first user U _k wishes to change the scheduled disembarking time (when the first request signal S _r1 includes information indicating a desire to change the first scheduled disembarking time t _{e_k} ), the changeable range calculation unit 28 sets the first fixed location G1 to the first planned boarding location p _{s_k} , the changed location Va to the first planned disembarking location p _{e_k} , and the second fixed location G2 to the second planned boarding location P2. Note that since the first scheduled boarding time t _{s_k} , the first planned boarding location p _{s_k} , the first planned disembarking location p _{e_k} , and the first planned disembarking location p _{e_k} are not affected by the reservation change, the zeroth travel time Δt0 and the first travel time Δt1 can be regarded as fixed values m0 and m1, respectively. Therefore, the changeable range calculation unit 28 can calculate the changeable range R based on the following equation (3) in which the first scheduled disembarking time t _{e_k} is a variable, by reflecting the conditions specified in the scene shown in Figure 7 in equation (1).

[Third embodiment]
Hereinafter, the third embodiment will be described. The same elements as those in the first or second embodiment will be denoted by the same reference numerals, and the description thereof will be omitted. In this embodiment, the calculation of the changeable range R when the first planned boarding location p _{s_k} or the first planned disembarking location p _{e_k} is changed will be described.

(Change of first boarding location p _{s_k} )
FIG. 9 is a diagram for explaining the calculation of the changeable range R when a change to the first planned boarding location p _{s_k} is assumed.

9, when the first user U _k wishes to change the planned boarding time (when the first request signal S _r1 includes information indicating a desire to change the first planned boarding location p _{s_k} ), the changeable range calculation unit 28 sets the first fixed location G1 to the previous user's planned disembarking location P0, the change location Va to the first planned boarding location p _{s_k} , and the second fixed location G2 to the first planned disembarking location p _{e_k} . Then, the changeable range calculation unit 28 can calculate the changeable range R based on the following formula (4) by reflecting the conditions specified in the scene shown in FIG. 9 in formula (1).

In formula (4), the previous user's planned disembarking time T0 and the permissible arrival time Tb are fixed values. Therefore, the changeable range calculation unit 28 can define the changeable range R as a region defined by two variables, the 0th travel time Δt0 and the 1st travel time Δt1.

(Change of first planned drop-off point p _{e_k} )
FIG. 10 is a diagram for explaining the calculation of the changeable range R when a change to the first planned alighting point p _{e_k} is assumed.

10, when the first user U _k wishes to change the planned disembarking time (when the first request signal S _r1 includes information indicating a desire to change the first planned disembarking location p _{e_k} ), the changeable range calculation unit 28 sets the first fixed location G1 to the first planned boarding location p _{s_k} , the change location Va to the first planned disembarking location p _{e_k} , and the second fixed location G2 to the second planned boarding location P2. Then, the changeable range calculation unit 28 can calculate the changeable range R based on the following formula (5) by reflecting the conditions specified in the scene shown in FIG. 10 in formula (1).

In formula (5), the first scheduled boarding time T1 and the second scheduled boarding time T2 are fixed values. Therefore, similarly to the case where the first planned boarding location p _{s_k} is changed, the changeable range calculation unit 28 can determine the changeable range R as a region defined by two variables, the 0th travel time Δt0 and the first travel time Δt1.

The following describes each of the configurations provided in the present embodiment described above and the associated effects.

In this embodiment, when the server 20 receives a request (first request signal _Sr1 ) from the first user terminal _UTk to present the changeable range R for the first planned boarding location _{ps_k} , the changeable range calculation unit 28 sets the planned disembarking location (previous user's planned disembarking location P0) of the previous user Uk _-1 who receives the vehicle dispatch processing immediately before the first vehicle dispatch processing as the first fixed location G1, sets the first planned boarding location _{ps_k} as the change location Va, and sets the first planned disembarking location _{pe_k} as the second fixed location G2 to calculate the changeable range R.

This realizes a specific calculation logic for determining the changeable range R that does not delay the start of the second vehicle dispatch process when the first user U _k wishes to change the first planned boarding location p _{s_k} .

On the other hand, in this embodiment, when the server 20 receives a request (first request signal _Sr1 ) for presentation of the changeable range R for the first planned disembarking location p _{e_k} from the first user terminal UT _k , the changeable range calculation unit 28 sets the first planned boarding location p _{s_k} as the first fixed location G1, sets the first planned disembarking location p _{e_k} as the change location Va, and sets the planned boarding location (second planned boarding location P2) of the second user who is provided with the second vehicle dispatch processing as the second fixed location G2, and calculates the changeable range R.

This realizes a specific calculation logic for determining the changeable range R that does not delay the start of the second vehicle dispatch process when the first user U _k wishes to change the first planned disembarkation location p _{e_k} .

[Fourth embodiment]
The fourth embodiment will be described below, with the same reference numerals being used to designate the same elements as those in any of the first to third embodiments, and the description thereof will be omitted.

In this embodiment, based on the configuration described in the third embodiment, a scene is assumed in which a shared vehicle V is undergoing a dispatch operation within a dispatch area A, and an example is described in which the changeable range R is corrected based on the current location of the shared vehicle V (hereinafter also referred to simply as "vehicle current location p _v ").

First, we will explain specific examples of scenes to which the control according to this embodiment is applied, with reference to Figures 11A to 11E.

More specifically, both Fig. 11A and Fig. 11B assume a situation in which the changeable range R is corrected when the shared vehicle V is moving toward the previous user's planned drop-off location P0 (previous user's vehicle dispatch process is being executed). In particular, Fig. 11A is a diagram for explaining the correction of the changeable range R when the first planned boarding location p _{s_k} is changed under this situation. Also, Fig. 11B is a diagram for explaining the correction of the changeable range R when the first planned drop-off location p _{e_k} is changed under the same situation.

The correction of the changeable range R in the scenes shown in Figures 11A and 11B is performed assuming, for example, the possibility that the time when the shared vehicle V actually arrives at the previous user's planned disembarkation location P0 is delayed from the expected time (previous user's planned disembarkation time T0), and the previous user's vehicle dispatch process is not completed according to the schedule specified in the above reservation data Bd _u .

11C and 11D, a case is assumed in which the changeable range R is corrected in a situation in which the vehicle is traveling from the previous user's planned drop-off location P0 to the first planned boarding location p _{s_k} (i.e., when picking up the first user U _k to execute the first vehicle dispatch process). In particular, FIG. 11C is a diagram for explaining the correction of the changeable range R in a case in which the first planned boarding location p _{s_k} is changed under this situation. Also, FIG. 11D is a diagram for explaining the correction of the changeable range R in a case in which the first planned disembarking location p _{e_k} is changed under the same situation.

The correction of the changeable range R in the scene shown in Fig. 11C is performed, for example, assuming the possibility that the shared vehicle V heading to the first planned boarding location p _{s_k} will change its travel route so as to head to the changed first planned boarding location p _{s_k} . Also, the correction of the changeable range R in the scene shown in Fig. 11D is performed, for example, assuming the possibility that the progress of the first vehicle dispatch process will be faster or slower than expected.

Furthermore, Figure 11E is a figure that explains the correction of the changeable range R in a situation where the first user U _k has already boarded the shared vehicle V and is traveling from the first planned boarding location p _{s_k} to the first planned disembarking location p _{e_k} (i.e., while the first vehicle dispatch process is being executed).

The correction of the changeable range R in the scene shown in FIG. 11E is performed, for example, assuming the possibility that the shared vehicle V heading toward the first planned disembarking location p _{e_k} will change its driving route so as to head toward the changed first planned disembarking location p _{e_k} .

The vehicle dispatch system 10 (particularly the server 20 of the vehicle dispatch reservation management system 15) of this embodiment has a function for correcting the changeable range R based on the vehicle current position p _v acquired in real time so as not to delay the start of the second vehicle dispatch process even in the scenes exemplified in Figures 11A to 11E. A specific configuration for realizing this function will be described below.

Figure 12 is a diagram explaining the configuration of the vehicle dispatch system 10 of this embodiment. Also, Figure 13 is a diagram explaining the vehicle dispatch reservation management system 15 of this embodiment. Note that, for simplification, Figure 13 mainly shows the configuration of the server 20 in the vehicle dispatch reservation management system 15, and omits the description of the configuration of the user terminal UT.

As shown in the figure, the vehicle dispatch system 10 and vehicle dispatch reservation management system 15 of this embodiment differ from the first embodiment in _{that the changeable range calculation unit 28 of the server 20 is mounted on, for example, an external device or a shared vehicle V and acquires the vehicle current position p v from} a self-position detection sensor, and calculates a corrected changeable range R (hereinafter also simply referred to as the ``corrected changeable range R _c '') based on the acquired vehicle current position p v.

14 is a flowchart for explaining the details of the calculation of the correction changeable range _Rc in this embodiment. Note that the changeable range calculation unit 28 repeatedly executes each process defined in this flowchart at a predetermined calculation cycle.

In step S110, the changeable range calculation unit 28 acquires the current vehicle position p _v . In particular, the changeable range calculation unit 28 stores the current vehicle position p _v in an internal memory or the like of the server 20 together with the time of acquisition of the current vehicle position p v (hereinafter also simply referred to as the “current time t _pv ”).

Next, the changeable range calculation unit 28 performs the judgment in step S120 and the subsequent judgment in step S130.

In the judgment of step S120, the changeable range calculation unit 28 judges whether or not the shared vehicle V has passed the previous user's planned disembarking location P0 based on the acquired vehicle current location _pv and current time _tpv . For example, the changeable range calculation unit 28 judges whether or not the current time _tpv has passed the previous user's planned disembarking time T0 and the vehicle current location _pv is located on the travel route from the previous user's planned disembarking location P0 to the first planned boarding location _{ps_k} . If the judgment result of step S120 is positive, the changeable range calculation unit 28 proceeds to step S130.

On the other hand, in the determination of step S130, the changeable range calculation unit 28 determines whether or not the shared vehicle V has passed the first planned boarding location p _{s_k} , based on the acquired vehicle current location p _v and current time t _pv . For example, the changeable range calculation unit 28 determines whether or not the current time t _pv has passed the first planned boarding time t _{s_k} , and the vehicle current location p _v is located on the travel route from the first planned boarding location p _{s_k} to the first planned disembarking location p _{e_k} .

Then, when the determination result of step S120 is negative, the changeable range calculation unit 28 proceeds to step S140 and calculates the first corrected changeable range R _c1 . Specifically, when the first planned boarding location p _{s_k} is to be changed (when the scene is as shown in FIG. 11A ), the changeable range calculation unit 28 calculates the first corrected changeable range R _c1 based on the following formula (6).

" _Tc0 " in formula (6) is a correction value of the previous user's scheduled disembarking time T0 (hereinafter also referred to as "pre-correction user's scheduled disembarking time _Tc0 "). In particular, the changeable range calculation unit 28 calculates the predicted travel time of the shared vehicle V from the vehicle current position _pv to the previous user's scheduled disembarking location P0, and calculates the pre-correction user's scheduled disembarking time _Tc0 by adding the predicted travel time to the current time _tpv . Note that formula (6) is essentially a replacement of "T0" in formula (4) with " _Tc0 ".

Next, when the first planned alighting location p _{e_k} is changed (when the scene is as shown in FIG. 11B ), the changeable range calculation unit 28 calculates the first corrected changeable range R _c1 based on the following formula (7).

Here, " _Tc1 " in formula (7) is a correction value of the first scheduled boarding time T1 (hereinafter also referred to as "corrected first scheduled boarding time _Tc1 "). In particular, the changeable range calculation unit 28 calculates a predicted travel time of the shared vehicle V from the vehicle current location _pv to the first scheduled boarding location _{ps_k} via the previous user's planned disembarking location P0, and calculates the corrected first scheduled boarding time _Tc1 by adding the predicted travel time to the current time _tpv . Note that formula (7) is essentially a replacement of "T1" in formula (5) with " _Tc1 ".

Next, when the determination result of step S120 is positive and the determination result of step S130 is negative, the changeable range calculation unit 28 proceeds to step S150 and calculates the second corrected changeable range R _c2 . Specifically, when the first planned boarding location p _{s_k} is to be changed (when the scene is as shown in FIG. 11C ), the changeable range calculation unit 28 calculates the second corrected changeable range R _c2 based on the following formula (8).

Here, "T _G1c " in the formula (8) is a correction value of the first fixed location scheduled arrival time T _G1 (hereinafter, also referred to as "corrected first fixed location scheduled arrival time T _G1c "). In particular, the changeable range calculation unit 28 sets the corrected first fixed location scheduled arrival time T _G1c to the same time as the current time t _pv . Also, "Δt _c 0" represents a correction value of the 0th travel time Δt0 (hereinafter, "corrected 0th travel time Δt _c 0 "). In particular, the changeable range calculation unit 28 calculates a predicted travel time on a travel route from the vehicle current position p _v , which is the corrected first fixed location G1, to the changed first planned boarding location p _{s_k} , and sets this as the corrected 0th travel time Δt _c 0. Note that the formula (8) is substantially a replacement of "T0" in the formula (4) with "T _G1c " and "Δt0" with "Δt _c 0".

On the other hand, when the first planned alighting location p _{e_k} is changed (in the case of the scene shown in FIG. 11D ), the modifiable range calculation unit 28 calculates the second corrected modifiable range R _c2 based on the following formula (9).

In this case, the changeable range calculation unit 28 calculates the corrected 0th travel time Δt _c 0 as the predicted travel time on the travel route (the travel route represented by the thick solid line in FIG. 11D ) from the vehicle current position p _v (the corrected first fixed position G1) via the first planned boarding position p _{s_k} to the changed first planned disembarking position p _{e_k} . Equation (9) is essentially equation (5) in which "T1" is replaced with "T _G1c " and "Δt0" is replaced with "Δt _c 0".

Next, if the determination result in step S130 is negative (the case is the scene shown in FIG. 11E), the changeable range calculation unit 28 proceeds to step S150 to calculate the third correction changeable range R _c3 . Specifically, the changeable range calculation unit 28 calculates the third correction changeable range R _c3 based on the above formula (9) in the same way as in the case of FIG. 11D.

However, in this case, the changeable range calculation unit 28 calculates the corrected 0th driving time Δt _c 0 as the predicted driving time for the driving route (the driving route represented by the thick solid line in Figure 11E) from the vehicle current position p _v to the changed first planned disembarking location p _{e_k} .

Then, the changeable range calculation unit 28 calculates the correction changeable range _Rc as any one of the first correction changeable range _Rc1 , the second correction changeable range _Rc2 , and the third correction changeable range _Rc3 according to the determination logic described above in Fig. 14. Furthermore, the server 20 replaces the calculated changeable range R with the correction changeable range _Rc and executes the subsequent processes (such as transmission to the display processing unit 52).

The following describes each of the configurations provided in the present embodiment described above and the associated effects.

In the vehicle dispatch system 10 or the vehicle dispatch reservation management system 15 of this embodiment, the changeable range calculation unit 28 of the server 20 acquires the vehicle current position p _v , which is the current position of the shared vehicle V, and corrects the changeable range R based on the acquired vehicle current position p _v .

This allows the changeable range R to be appropriately corrected according to the current location of the shared vehicle V while the dispatch operation is being performed. Therefore, a more accurate calculation logic for the changeable range R is realized that takes into account the progress of the actual dispatch operation.

In particular, by using the changeable range R in this manner for the subsequent processing described in the first embodiment above (display on the first user terminal UT _k , processing in the reservation change processing unit 30, and driving control on the in-vehicle terminal VT), the real-time behavior of the shared vehicle V during the dispatch operation is reflected in these processing as well.

[Fifth embodiment]
The fifth embodiment will be described below. Elements similar to those in any of the first to fourth embodiments are given the same reference numerals, and their description will be omitted. In this embodiment, in particular, one form of display processing of the changeable range R in the display unit (display processing unit 52 and display 54) of the first user terminal UT _k will be described.

Figures 15 and 16 are diagrams explaining the process for displaying the changeable range R in this embodiment.

Figure 15 shows a first circular area S _G1 (radius = Δt0) corresponding to the range that the shared vehicle V can reach within the zeroth driving time Δt0, starting from the first fixed point G1 (see Figure 5), and a second circular area S _G2 (radius = Δt1) corresponding to the range of the shared vehicle V that can arrive at the second fixed point G2 within the first driving time Δt1.

In particular, in Fig. 15(a) to Fig. 15(f), the first circular area S _G1 and the second circular area S _G2 are shown when the zeroth travel time Δt0 and the first travel time Δt1 are changed stepwise with an arbitrary base time t b as a reference. More specifically, the first circular area S _G1 and the second circular area S _G2 are shown when the zeroth travel time Δt0 is increased at 10 min intervals while the first travel time Δt1 is decreased at 10 min intervals. In addition, each of the first circular area S _G1 and the second circular area S _G2 shown in Fig. 15(a) to Fig. 15( _f ) satisfies the condition that the sum of the zeroth travel time Δt0 and the first travel time Δt1 is a predetermined value (particularly, 70 min). This predetermined value is set so that the time obtained by adding the predetermined value to the base time t _b is equal to or shorter than the allowable arrival time Tb. That is, each of the first circular areas S _G1 and each of the second circular areas S _G2 is determined as an area that satisfies the condition of formula (1). Note that the specific numerical values in this embodiment are shown for the convenience of explanation and do not limit the technical scope of the present invention.

Therefore, each of the first circular regions S _G1 in FIG. 15(a) to FIG. 15(f) represents a range that the shared vehicle V can reach by departing from the first fixed location G1 when 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes, 60 minutes, and 70 minutes have passed since the base time t _b . On the other hand, each of the second circular regions S _G2 in FIG. 15(a) to FIG. 15( _f ) represents a range of the shared vehicle V that can reach the second fixed location G2 within 70 minutes, 60 minutes, 50 minutes, 40 minutes, 30 minutes, 20 minutes, and 10 minutes from the same base time t b. Therefore, each two-dimensional region S determined as a common region of each of the first circular regions S _G1 and each of the second circular regions S _G2 becomes a candidate region of the change location Va that can be set to satisfy the formula (1). Therefore, the changeable range calculation unit 28 of this embodiment calculates this as the changeable range R.

Figures 16(a) to 16(f) show the two-dimensional regions S defined in Figures 15(a) to 15(f). For ease of explanation, the two-dimensional regions S shown in Figures 16(a) to 16(f) are denoted by the symbols "S1", "S2", "S3", "S4", "S5", and "S6", respectively.

Furthermore, FIG. 17 shows the two-dimensional regions S1, S2, S3, S4, S5, and S6 superimposed on a single two-dimensional plane. Therefore, the changeable range R is calculated as the entire area formed by superimposing the two-dimensional regions S1, S2, S3, S4, S5, and S6. The changeable range calculation unit 28 transmits the changeable range R formed by superimposing the two-dimensional regions S1, S2, S3, S4, S5, and S6 to the display processing unit 52.

Furthermore, the display processing unit 52 generates display data based on the received changeable range R. Specifically, the display processing unit 52 generates the above-mentioned display data by overlaying the changeable range R on real map data including the dispatch area A stored in an internal memory or the like. Then, the display processing unit 52 displays the generated display data on the display 54.

Fig. 18 is a diagram showing an example of a display mode in which the changeable range R is superimposed on actual map data. In the example shown in Fig. 18, the areas in which the changed location Va can be set for each elapsed time from the base time _tb are represented as two-dimensional areas S1, S2, S3, S4, S5, and S6. Therefore, according to this embodiment, it is possible to determine and display candidates for the changed location Va (the changed first planned boarding location p _{s_k} or the changed first planned disembarking location p _{e_k} ) related to the reservation change according to the _elapsed time from the base time tb.

In particular, the display mode of this embodiment is based on the definitions of the second to fourth embodiments in which the "first fixed location G1", "changed location Va", and "second fixed location G2" defined in the first embodiment are more specifically defined, and by executing the display mode shown in Fig. 18, a display variation is realized that allows the first user U _k to appropriately recognize the changeable range R through his/her vision. For example, when it is desired to change the planned boarding location before boarding (the scene shown in Fig. 11A or Fig. 11B), if the changed location Va is set to the first planned boarding location p _{s_k} and the elapsed time of a predetermined time interval from an arbitrary base point time t _b (every 10 minutes in Fig. 18), candidates for the change destination of the first planned boarding location p _{s_k} by time can be displayed.

More specifically, the changeable range R can be obtained as an area determined as the sum of two-dimensional areas S1 to S6 when the first planned boarding location p _{s_k} is changed within 10 minutes from the base time t _b , an area determined as the sum of two-dimensional areas S2 to S6 when the location is changed between 10 and 20 minutes later, an area determined as the sum of two-dimensional areas S3 to S6 when the location is changed between 20 and 30 minutes later, an area determined as the sum of two-dimensional areas S4 to S6 when the location is changed between 30 and 40 minutes later, an area defined as the sum of two-dimensional areas S5 to S6 when the location is changed between 40 and 50 minutes later, and an area represented by the two-dimensional area S6 when the location is changed between 50 and 60 minutes later. In particular, in the scene of Figure 11A, the base time t _b is set to the user's pre-corrected scheduled disembarkation time T _c 0, in the scene of Figure 11B, the base time t _b is set to the corrected first scheduled boarding time T _c 1, and in the scenes of Figures 11C to 11E, the base time t _b is set to the current time t _pv (corrected first scheduled arrival time at fixed location T _G1c ), making it possible to appropriately realize the display mode of the changeable range R shown in Figure 18.

The following describes each of the configurations provided in the present embodiment described above and the associated effects.

In the vehicle dispatch system 10 or the vehicle dispatch reservation management system 15 of this embodiment, the changeable range R is calculated as two-dimensional areas S1 to S6 according to the elapsed time from a predetermined base point time t _b . The two-dimensional areas S1 to S6 are a common area between a first circular area S _G1 as an area that can be reached from a first fixed point G1 as a starting point that the shared vehicle V passes just before the changed point Va, and a second circular area S _G2 as an area that the shared vehicle V can reach a second fixed point G2. The display processing unit 52 of this embodiment displays the two-dimensional areas S1 to S6 superimposed on real map data including the vehicle dispatch area A.

This makes it possible to realize various display modes for allowing the first user _Uk to recognize the changeable range R. Furthermore, since the changeable range R is displayed superimposed on a real map within the vehicle allocation area A, it is possible to promote visual recognition of the changeable range R by the first user _Uk .

Although each embodiment of the present invention has been described above, the above embodiments merely show some of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.

For example, each hardware configuration and software configuration of the dispatch system 10 in each of the above embodiments is one aspect, and can be changed as desired within the technical scope of the present invention. As an example, each hardware configuration and software configuration in the dispatch system 10 may be realized by a single computer, or may be realized by integrating the functions of multiple computers as appropriate. For example, in the above embodiments, each function of the server 20 as a dispatch reservation data management device may be distributed to a user terminal UT, an in-vehicle terminal VT, or various other hardware resources physically separated from the server 20 as necessary.

In addition, in each of the above embodiments, an example is described in which the vehicle dispatch system 10 includes one shared vehicle V, in order to simplify the explanation. However, the calculation logic of each of the above embodiments can be applied to each shared vehicle V even in a scene in which multiple shared vehicles V belong to the vehicle dispatch system 10 and vehicle dispatch processing related to multiple users U is set for any of the multiple shared vehicles V within a specified time period.

Furthermore, in each of the above embodiments, it is assumed that a request (first request signal _Sr1 ) for confirming the change range of the reservation contents and a request (second request signal _Sr2 ) for actually instructing the change of the reservation contents are generated separately. However, a configuration may be adopted in which both of these requests are accepted simultaneously, and processing such as output of the changeable range R to the first user terminal _UTk and updating of the reservation management DB 22 based on the acceptance of the change are simultaneously executed. Also, a configuration may be adopted in which the in-vehicle terminal VT is provided with a function similar to that of the display unit of the first user terminal _UTk , and the changeable range R is displayed when the user U is in the shared vehicle V. Furthermore, the function of performing the calculation processing for display in the display processing unit 52 of the first user terminal _UTk may be realized by the hardware and software configuration of the server 20, or may be distributed to the hardware and software configurations of the server 20 and the first user terminal _UTk or the in-vehicle terminal VT.

In the second embodiment, the example of estimating the scenes shown in Figures 11A to 11E based on the vehicle current position p _v and calculating the corrected changeable range R has been described. However, instead of this, any information indicating the progress of the current vehicle dispatch operation may be stored in any storage area accessible by the server 20, and the current state may be determined to correspond to any of the scenes shown in Figures 11A to 11E by referring to the information or by referring to both the information and the vehicle current position p _v . This makes it possible to identify each of the scenes shown in Figures 11A to 11E with higher accuracy, for example, even in a case where the driving route related to the vehicle dispatch process of the first user U _k and the driving route related to the vehicle dispatch process of a different user U are partly common in the vehicle dispatch operation.

In addition, the scope of matters described in the specification, etc. at the time of filing of this application includes a vehicle dispatch reservation data management method in which reservation data Bd _u indicating the reservation contents related to each vehicle dispatch process for multiple users U who use a shared vehicle V is managed by a server 20 as a computer.

In particular, in this vehicle dispatch reservation data management method, the server 20 refers to a reservation management DB 22 as a storage unit that stores reservation data Bd _u indicating reservation details (scheduled boarding time t _s , planned boarding location p _s , scheduled disembarking time t _e , and planned disembarking location p _e related to the vehicle dispatch process (such as the first vehicle dispatch process and the second vehicle dispatch process) for _{each of} a plurality of users U in association with the identification information (such as the user name) of each user U. Then, the server 20 identifies (identifying unit 26) second reservation data Bd _uk+1 related to the second vehicle dispatch process to be executed following the first vehicle dispatch process defined by the first reservation data Bd _uk from the first reservation data Bd uk linked to the first user U _k .

Furthermore, the server 20 is caused to calculate a changeable range R of the reservation contents related to the first vehicle dispatch process based on the identified first reservation data Bd _uk and second reservation data. In particular, in this vehicle dispatch reservation data management method, the server 20 is caused to calculate the changeable range R so that the shared vehicle V arrives at the planned boarding location p _s of the second vehicle dispatch process before the planned boarding time t _s of the second vehicle dispatch process (changeable range calculation unit 28).

The configurations of the above-mentioned embodiments can be combined with each other to the extent that there is no logical contradiction. For example, by combining the second embodiment and the third embodiment, it is possible to update the display of the change destination candidate of the planned boarding place (or the planned disembarking place) according to the planned boarding time shown in _FIG . 13 in real time according to the vehicle current position p v (the progress status of the current dispatch operation).

In the above embodiments, an example has been described in which the changeable range R is calculated and displayed on the assumption that any one of the first scheduled boarding time t _{s_k} , the first scheduled disembarking time t _{e_k} , the first scheduled boarding location p _{s_k} , and the first scheduled disembarking location p _{e_k} is changed when changing a reservation. On the other hand, when two or more of these elements are changed, a configuration may be adopted in which the calculation logic explained in the above embodiments is executed to calculate the changeable range R for each element, and a single changeable range R that integrates the results of each calculation is generated, and this is displayed by the display processing unit 52.
