Further, the control device 230 accesses the shared vehicle management device 100 via the communication device 220, acquires the information of the request for using the shared vehicle Vn, and performs user authentication of the user who boarded the shared vehicle Vn.

Control device 230 also transmits current position information acquired using GPS receiver 210 to shared vehicle management device 100 via communication device 220 . Thereby, the control device 10 included in the shared vehicle management device 100, which will be described later, can acquire the current position information of each shared vehicle Vn.

Furthermore, the control device 230 notifies the user of the information transmitted from the shared vehicle management device 100 by using a display, a speaker, and the like (not shown). In this embodiment, the control device 230 receives, from the shared vehicle management device 100, information about users who wish to ride together on the shared vehicle Vn, and notifies the users. Riding together in the present embodiment means that a plurality of people ride together in one shared vehicle, for example, it means that different people ride in one shared vehicle. In the following description, when a plurality of users ride together in one shared vehicle Vn, the shared vehicle Vn is referred to as a shared vehicle.

When the shared vehicle Vn has an automatic driving function, the control device 230 controls the shared vehicle Vn to travel along the travel route transmitted from the shared vehicle management device 100 . When the shared vehicle Vn does not have an automatic driving function, the control device 230 displays the travel route transmitted from the shared vehicle management device 100 on the vehicle-mounted display included in the navigation system.

The shared vehicle management device 100 of the present embodiment functions as a server of the shared vehicle management system 1, and includes a control device 10 that executes control processing for managing and operating the car sharing system, an in-vehicle device 200Vn, and a user terminal device 400A. A communication device 20 that can communicate with each other, and a database 30 that stores information received by the communication device 20, information on each shared vehicle Vn, and the like.

The database 30 stores shared vehicle information 31 , usage requests 32 received from users, map information 33 , user information 34 , and traffic information 35 .

The shared vehicle information 31 is information about each shared vehicle Vn. The shared vehicle information 31 includes information on the current position of each shared vehicle Vn, remaining power capacity and failure information of each shared vehicle Vn, current usage status of each shared vehicle Vn, and the like.

The usage request 32 is usage request information for the shared vehicle Vn input by each user via the user terminal device 400A. The use request 32 includes ID information of the user, ID information of the shared vehicle Vn that the user intends to use, information on the current position of the user, boarding position (departure point) set by the user, alighting position (destination), boarding Information indicating the scheduled time (scheduled departure time), scheduled alighting time (scheduled arrival time), and the like are included. The scheduled boarding time and the scheduled alighting time may each have a time width. For example, if the user wishes to arrive at the specified drop-off position between 10:30 a.m. and 11:30 a.m., the estimated arrival time is a time span of around 30 minutes centered around 11:00 a.m. is indicated by Similarly, the scheduled departure time is also indicated by a time with an arbitrary time width centered on an arbitrary time.

The map information 33 is map information including information such as roads and facilities. The facility information includes, for example, building structure information indicating the number of floors of the building, passages of the building, entrances and exits of the building, and the like. Further, the map information 33 includes, for example, positional information of each station, facility information around each station, traffic conditions around each station, and information about each station such as usage conditions of each station.

The user information 34 is information of all users who can use the car sharing system. The user information 34 includes ID information of all users and information of current locations of all users. For example, the current location information of each user can be stored in the user information 34 by the communication device 20 receiving the current location information of each user from the user terminal device 400A of each user at predetermined intervals.

The traffic information 35 is information, such as congestion information and traffic control information, that affects the running of the shared vehicle Vn. The traffic information is obtained from a system for managing road traffic information, such as VICS (registered trademark). FIG. 2 is a graph schematically showing the probabilities of occurrence of traffic jams on a certain road for one day. In the example of FIG. 2, the congestion occurrence probability is high around 7:00 and around 18:00. The database 30 stores the probability of occurrence of traffic congestion on each road as traffic information 35 in association with combinations of weekdays, holidays, weather, and the like. Note that the traffic information 35 is not limited to the congestion occurrence probability as shown in FIG. 2, and may be indicated by, for example, the number of occurrences of congestion.

As shown in FIG. 1, the control device 10 of the shared vehicle management device 100 of the present embodiment includes a ROM (Read Only Memory) 12 storing a program for executing processing for managing and operating the car sharing system; By executing a program stored in the ROM 12, a CPU (Central Processing Unit) 11 as an operation circuit functioning as the shared vehicle management device 100 and a RAM (Random Access Memory) 13 functioning as an accessible storage device are operated. Prepare.

An example of a form of car sharing will be described with reference to FIG. FIG. 3 is a schematic diagram showing an example of a method for the user U1 to use the shared vehicle V1 in the shared vehicle management system 1 of this embodiment. FIG. 3 shows a scene where the user U1 uses the user terminal device 400A to use the shared vehicle V1 to move from the starting point P1 set by the user U1 to the destination P2.

For example, in the scene shown in FIG. 3, when the user U1 inputs the departure point P1 and the destination P2 to the user terminal device 400A, the input information is used as the desired conditions when the user U1 uses the shared vehicle. It is transmitted from the device 400A to the shared vehicle management device 100. FIG.

The shared vehicle management device 100 transmits a movement command to the shared vehicle V1 selected based on the desired conditions to move to the departure point P1 and pick up the user U1. The movement command includes a travel route from the current position of the shared vehicle V1 to the departure point P1 and a travel route R1 from the departure point P1 to the destination P2. When the shared vehicle V1 receives a movement command from the shared vehicle management device 100, the shared vehicle V1 automatically travels to the starting point P1 unmanned by the automatic driving function. Then, when the user U1 gets on at the departure point P1, the shared vehicle V1 automatically travels to the destination P2 along the travel route R1 included in the movement command. When the shared vehicle V1 arrives at the destination P2, the user U1 gets off and ends the use of the shared vehicle V1. After that, the shared vehicle V1 moves to a station within a predetermined range from the destination P2.

In this embodiment, the user can set arbitrary points such as railway stations and commercial facilities as the starting point and destination.

In the scene shown in FIG. 3, the user U2 is a user who can use the shared vehicle V1, like the user U1. For example, if the car sharing system is limited to members who have registered as users, both user U1 and user U2 are members who have registered as users. The user U2 operates the user terminal device 400B and transmits desired conditions to the shared vehicle management device 100. FIG. The user U2 receives information including the travel plan of the shared vehicle V1 and information for confirming whether or not he or she wishes to ride together from the shared vehicle management device 100 through the user terminal device 400B. The travel plan includes a travel route R2 for sharing. The user U2 confirms the travel plan such as the travel route displayed on the user terminal device 400B, and transmits a signal to the vehicle management device 100 indicating that the shared vehicle V1 is to be shared.

The vehicle management device 100 changes the travel plan from the non-ride-sharing travel route R1 to a ride-share travel route R2 so that the shared vehicle V1 can be shared between the user U1 and the user U2. Although the estimated time of arrival at the destination of user U1 is delayed due to the change of the travel route, if the estimated time of arrival is within the allowable range for user U1, vehicle management device 100 determines that the ridesharing condition is satisfied. Then, the vehicle management device 100 transmits the changed travel route R2 to the shared vehicle V1, and the shared vehicle V1 travels on the travel route R2.

Next, control processing of the shared vehicle management device 100 will be described. FIG. 4 is a flow chart showing a control flow by the control device 10 of the shared vehicle management device 100. As shown in FIG.

In step S101, the control device 10 communicates with the user terminal device 400A and acquires desired conditions from the user. Desired conditions are conditions specified by the user when using the shared vehicle 200 . Desired conditions are designated by boarding position, alighting position, desired boarding time, desired alighting time, and the like. The boarding position and the alighting position are positions specified by the user on a map displayed on the display device 430 of the user terminal device 400A, for example. The boarding position and the alighting position are indicated by latitude and longitude, for example. Note that the boarding position and the alighting position may be designated by an area such as, for example, the vicinity of Yokohama Station. Alternatively, the user may input a desired departure point or destination to the user terminal device 400A, and the control device 10 may set the boarding position and the alighting position around the departure point or the destination, respectively. The boarding position based on the departure point and the drop-off position based on the destination are positions suitable for stopping the shared vehicle Vn. The starting point and boarding position may be the same point, and the destination and getting off position may be the same point.

The desired boarding time and desired alighting time are not limited to a specific time, and may be specified in a time period such as 8:00 AM to 9:00 AM. Note that the desired condition does not necessarily include the desired boarding time or desired alighting time. For example, when the user desires to board the shared vehicle 200 as soon as possible, the desired condition does not include the desired boarding time.

The desired alighting time may be set within a time range allowed for carpooling. As described above, when the travel route is changed by sharing a ride, the scheduled alighting time is later than the time until the travel route is changed. When the user designates the desired time to get off the vehicle by a time width, this time width is within an allowable range for the delay of the getting off time due to shared rides. In other words, if the scheduled alighting time is delayed due to carpooling, if the scheduled alighting time after the change is within the allowable range of the desired alighting time, the carpooling is permitted.

The desired conditions may include whether or not there is a desire to ride together. For example, if the usage fee of the shared vehicle 200 when sharing a ride is lower than the fee when not sharing a ride, whether or not the user desires to share a ride is determined in order to enable the user to request sharing when applying for a reservation. Included in the desired conditions.

Desired conditions acquired from users are stored in the database 30 .

In step S102, the control device 10 identifies a vehicle that can be used from among the plurality of shared vehicles Vn based on the desired conditions acquired from the user. The control device 10 selects a shared vehicle Vn that meets the desired conditions. For example, the control device 10 selects the shared vehicle Vn closest to the boarding position specified by the desired condition as an available candidate vehicle. When the desired conditions include the boarding position and the desired boarding time, the control device 10 determines whether or not the shared vehicle Vn can arrive at the boarding position by the desired boarding time. The control device 10 determines that the shared vehicle Vn can be used when determining that the shared vehicle Vn can arrive at the boarding position by the desired boarding time. If the shared vehicle Vn can be used, the control device 10 executes the control process of step S103.

In step S103, the control device 10 determines whether or not the ridesharing condition is satisfied based on the plurality of desired conditions acquired from the plurality of users. The control device 10 identifies users who can move from the desired drop-off position to the drop-off position by sharing the shared vehicle Vn specified by the control process of step S102 as users who can ride together. If the desired conditions include whether or not there is a desire to ride together, the control device 10 identifies users who are candidates for riding together from among the users who desire to ride together.

The control device 10 calculates the traveling route of the shared vehicle Vn when the user who is a ride-sharing candidate rides together. The travel route is a route from the boarding position to the alighting position of each user who is scheduled to board the shared vehicle Vn, including the users who are candidates for riding together. The control device 10 acquires the traffic information 35 from the database 30, and calculates the route with the shortest travel time of the vehicle based on the traffic information. The control device 10 acquires information about the probability of occurrence of traffic congestion as shown in FIG. 2 from the database 30, avoids roads where traffic congestion is expected, and calculates a route with the shortest travel time.

Next, the control device 10 calculates the scheduled boarding time and the scheduled alighting time when the calculated travel route is traveled. The control device 10 calculates the scheduled boarding time and the scheduled alighting time of each user who is scheduled to board the vehicle by carpooling. The control device 10 determines whether or not the scheduled getting-off time of the user who accepts the ride-sharing will be delayed by accepting the ride-sharing. In addition, when the scheduled alighting time is delayed by accepting the shared ride, the control device 10 determines whether the delay of the scheduled arrival time is within the allowable range. The allowable range is the time width specified by the user when making a reservation for the shared vehicle Vn, and is indicated by desired conditions. Then, when the delay of the scheduled arrival time is within the allowable range, the control device 10 determines that the ridesharing condition is satisfied. Thereby, the control device 10 identifies users and shared vehicles Vn (shared vehicles Vn) that can be shared based on the desired conditions of the plurality of users. On the other hand, if the delay in the scheduled arrival time is outside the allowable range, the control device 10 determines that the ridesharing condition is satisfied.

Note that the method of specifying a ride-sharing user and the method of specifying a ride-sharing vehicle are not limited to the above methods. For example, if the user who is currently using the vehicle is a female, the control device 10 acquires the user information 34 and selects the candidate ride-share users from among the female users when selecting the candidate ride-share users. may be specified.

If the ridesharing conditions are satisfied, in step S104, the control device 10 uses the communication device 20 to transmit the information indicating the travel plan and the reservation completion information to the user terminal device 400N. Notify the travel plan and reservation completion to Ride-sharing target users are users who ride in a shared vehicle, and include a user who rides together and a user who rides together. The travel plan is indicated by the scheduled departure time from the user's desired boarding position, the estimated arrival time at the user's desired disembarking position, the travel route, and the like. The reservation completion information includes information such as the fact that the reservation is completed, the fact that it is a shared ride, and the fare.

If the ridesharing conditions are not satisfied, the controller 10 notifies the user of the travel plan and reservation completion in step S105. The notified travel plan is a travel route when not sharing a ride. After notifying the user of the travel route and reservation confirmation, the control process shown in FIG. 4 ends.

In the control process of step S102, if there is no available shared vehicle, the control device 10 notifies the user that the reservation is not possible in step S106. As an example of the process executed in step S106, when the shared vehicle that meets the desired conditions cannot be identified, the control device 10 notifies the user that the shared vehicle cannot be used under the desired conditions. Then, the control process shown in FIG. 4 ends.

It should be noted that the above control flow is not limited to the case where the shared vehicle Vn is reserved before the user to be shared rides in the shared vehicle. may be applied to Even if the scheduled alighting time of a user who is on board is delayed by sharing a shared vehicle while riding, if the scheduled alighting time is within a permissible range, the control device 10 determines that the ridesharing conditions are satisfied. . Then, the control device 10 notifies the user who is riding in the vehicle of the changed travel plan. By confirming the notification, the user on board can recognize the changed scheduled alighting time and the changed travel route.

Next, specific control of the vehicle management apparatus 100 in a state where a plurality of users are riding in a shared vehicle will be described. FIG. 5 is a flow chart showing a control flow by the control device 10 of the shared vehicle management device 100. As shown in FIG. Note that the control flow shown in FIG. 5 is repeatedly executed at a predetermined cycle (for example, 10 ms).

In step S201, based on the travel plan, the control device 10 determines whether or not a plurality of users are currently riding together in the shared vehicle Vn. If not, the control flow shown in FIG. 5 ends.

If the vehicle is in a shared ride, the controller 10 acquires current traffic information in step S202. In step S203, the control device 10 calculates the estimated arrival time of the user who is the target of the ride-sharing based on the acquired current traffic information and the current position of the ride-sharing vehicle. A user who is a target of a shared ride corresponds to a user who is currently riding in a shared vehicle. The estimated arrival time calculated in step S203 may be later than each estimated arrival time calculated at the time of reservation of the shared vehicle Vn, depending on the current traffic information obtained or the condition of the road on which the vehicle is currently traveling.

For example, in the congestion occurrence probability shown in FIG. 2, the congestion occurrence probability on a certain road is low, but if the congestion occurs due to an unexpected event, the estimated arrival time will be delayed. For example, when an unexpected event (emergency event) such as an accident or construction work affects the running time of a vehicle, it causes a delay with respect to the arrival time, and thus can be a delay event. If the acquired current traffic information indicates the possibility of a delay due to an unexpected event, the control device 10 calculates the estimated arrival time based on the acquired current traffic information. Time delay can be grasped.

Further, even if the possibility of delay due to an unexpected event is not reflected in the traffic information acquired from the outside, the control device 10 may acquire the traffic information from the current running state. For example, if the road on which the vehicle is currently traveling is congested due to construction or the like, the current vehicle speed will be lower than the vehicle speed assumed when the travel route was calculated. Therefore, the control device 10 can acquire traffic information from the difference between the current running state of the vehicle and the expected running state when the total route is calculated. By calculating the estimated arrival time from the current running state, the control device 10 can grasp the delay of the estimated arrival time. It should be noted that the vehicle information of the traveling shared vehicle may be calculated from the position information of the shared vehicle, for example.

In step S204, control device 10 determines whether or not there is a delay in the calculated estimated arrival time. The control device 10 determines whether or not there is a delay for each estimated arrival time of each user who is a target of riding together. If there is no delay in the calculated estimated arrival time, the control process shown in FIG. 5 ends. If there is a delay in the calculated estimated arrival time, in step S205, the control device 10 determines whether the delay in the estimated arrival time is outside the allowable range. If the delay in the estimated arrival time is within the allowable range, the control process shown in FIG. 5 ends. Then, if at least one of the delays of the estimated arrival times of the users who are candidates for riding together is outside the allowable range, the control device 10 determines that the delays of the estimated arrival times are outside the allowable range.

In the present embodiment, the control device 10 performs the control processing from step S203 to step S205, in a state in which the user who is the target of the shared ride is in the shared vehicle, based on the current position of the shared vehicle Vn and the traffic information. It predicts whether or not a delay event that causes a delay with respect to the user's scheduled alighting time has occurred. Then, when the occurrence of the delay event is predicted, the control device 10 determines that the delay of the user's scheduled arrival time is outside the allowable range, and executes the control process of step S206.

In step S206, control device 10 identifies a transfer vehicle. When at least one of the users who are subject to ride-sharing switches from the shared vehicle to another shared vehicle Vn, the shared vehicle Vn to which the shared vehicle is transferred corresponds to the transfer vehicle.

For example, assume that the first user boarded the shared vehicle first, and the second user boarded later. Then, assume that a delay event occurs during the shared ride, and the delay in the scheduled alighting time of the first user falls outside the allowable range of the scheduled alighting time that was fixed when the shared vehicle Vn was reserved. In such a case, in the present embodiment, control is executed to cause the second user to transfer from the shared vehicle to the transfer vehicle. By the second user changing to the transfer vehicle, the shared vehicle Vn after the second user gets off can travel on the shortest travel route to the first user's getting off position. Therefore, the delay of the first user's scheduled getting-off time can be suppressed.

The control device 10 identifies a transfer vehicle from among a plurality of shared vehicles Vn based on the current positions of the shared vehicles and the current positions of the shared vehicles Vn. In the above example, among the plurality of shared vehicles Vn, the shared vehicle that is scheduled to travel at or around the second user's drop-off position and travels on the travel route of the shared vehicle or around the travel route of the shared vehicle. Vehicle Vn is identified as a transfer vehicle. That is, the control device 10 identifies the transfer vehicle so as to optimize the traveling cost of the sharing vehicle and the traveling cost of the transfer vehicle based on the desired conditions of the second user and the traveling plan of the sharing vehicle. The travel cost is indicated by travel time, travel distance, or the like of the shared vehicle Vn. A method of specifying a transfer vehicle will be described later.

In step S207, the control device 10 sets a transfer position where the user transfers from the shared vehicle to the transfer vehicle. A point at which the travel route of the transfer vehicle and the travel route of the shared vehicle intersect, or a point at which the travel route of the transfer vehicle and the travel route of the shared vehicle approach each other is set as the transfer position. When setting the transfer position, the control device 10 specifies a transfer candidate position that is a candidate for the transfer position, and calculates the estimated arrival time of the transfer vehicle at the transfer candidate position and the estimated arrival time of the shared vehicle at the transfer candidate position. is calculated, and the transfer candidate position with the highest transfer efficiency is set as the transfer position. A method of setting the transfer position will be described later.

In step S208, control device 10 calculates a travel plan for the transfer vehicle. The travel plan of the transfer vehicle is calculated based on the desired conditions of the user who has transferred. Note that when another user is boarding the transfer vehicle at the time of transfer, or when another user has reserved the use of the transfer vehicle, the control device 10 Based on the user's desired conditions, a travel plan for the transfer vehicle is calculated.

In step S209, the control device 10 calculates a travel plan for the shared vehicle Vn after the sharing cancellation based on the desired conditions of the user. This user is a user who remains in the shared vehicle after the shared ride is canceled.

In step S210, the control device 10 updates the travel plan of the transfer vehicle and the travel plan of the shared vehicle Vn after the sharing cancellation.

In step S211, control device 10 notifies the user of the updated travel plan. The control device 10 transmits information about the updated travel plan to the shared vehicle Vn. Then, the in-vehicle device 200 of the traveling vehicle Vn notifies the user of the updated travel plan by displaying information about the updated travel plan on a display or the like. The control device 10 may also transmit information about the updated travel plan to the user terminal device 400 . Notification of the updated travel plan may include information that the scheduled arrival time will be delayed if the shared ride is continued. In addition, the notification to the user who will transfer to another vehicle may include information about the transfer vehicle. information, information on the estimated time of arrival at the transfer position, vehicle information of the transfer vehicle, or user information on the transfer vehicle. The information about the transfer vehicle is information to be notified to the user who continues to ride the shared vehicle, including information such as that the travel route will be changed due to the transfer, or that the shared vehicle will stop for the transfer. good too. After receiving the notification, the user confirms that the scheduled alighting time will be delayed if the carpool continues, that a transfer is proposed by the system, and that the delay in the scheduled alighting time can be reduced by changing the train. can. Then, the control processing shown in FIG. 5 ends.

Next, the control processing of the control device 10 will be described using a specific example. FIG. 6 is a conceptual diagram for explaining the travel route of the shared vehicle before updating. FIG. 7 is a conceptual diagram for explaining a situation when a delay event occurs on the travel route before the shared vehicle is updated. FIG. 8 is a conceptual diagram for explaining the updated travel route of the shared vehicle and the travel route of the transfer vehicle.

Desired conditions of user P and user Q who ride together will be described. The user P desires the position A as the boarding position and the position A' as the alighting position (destination). User Q wants position B as the boarding position and position B' as the getting off position. Position A and position B are the same point. The user P designates a desired boarding time at the boarding position A and a desired alighting time at the alighting position A'. Similarly, user Q designates a desired boarding time at boarding position B and a desired alighting time at alighting position B'. Also, the shared vehicle X departs from the position S. The user P gets on the shared vehicle X before the user Q. In the example of FIG. 6, the users P and Q share the shared vehicle X, and the shared vehicle X approaches the intersection d. It's running like Based on the desired conditions of the user P and the desired conditions of the user Q, the control device 10 passes target points including boarding positions A and B and alighting positions A' and B', and the estimated arrival time of each target point is set to the user X's. , Y is calculated to match the desired time. The traveling route Ra shown in FIG. 6 is a route calculated by the control device 10, and the traveling route Ra starts from the departure point S, travels through the intersections d, g, e, f, and c in order, and reaches the position A' as the destination. It is a route to Also, the travel route Ra passes through boarding positions A and B and alighting positions A' and B'.

The shared vehicle management device 100 communicates with the shared vehicle X while the shared vehicle X is running, and acquires information on the current position of the shared vehicle X. FIG. The shared vehicle management device 100 also acquires traffic information that affects the running of the shared vehicle X. FIG. The traffic information includes traffic congestion information occurring on the travel route Ra and prediction information of traffic congestion occurring on the travel route Ra. Based on the acquired traffic information and the current position of the shared vehicle X, the shared vehicle management device 100 calculates the estimated arrival times of the users X and Y (corresponding to the estimated arrival times at the drop-off positions A' and B'). The shared vehicle management device 100 compares the calculated estimated arrival time with the estimated arrival time when the reservation for the shared vehicle X is confirmed, and determines whether an event that causes a delay with respect to the estimated arrival time has occurred. to predict.

In the example of FIG. 7, a delay event such as traffic congestion occurs between intersection g and intersection e. When the delay event occurs between the intersection g and the intersection e, the drop-off position B′ is between the intersection g and the intersection e. ' late arrival time. Also, the arrival time at the drop-off position A' is delayed.

In this embodiment, as shown in the example of FIG. 7, when the delay in the scheduled arrival times of users P and Q who are riding together is outside the allowable range, user Q is transferred from shared vehicle X to another shared vehicle. A transfer vehicle is specified for transfer. When specifying a user to transfer, the shared vehicle management device 100 specifies the user who transfers to the transfer vehicle by prioritizing the user who has the lowest boarding order for the shared vehicle. In the example of FIG. 7, the boarding order of user Q when boarding the shared vehicle X is later than the boarding order of user P when boarding the shared vehicle X. Therefore, user Q is given priority over user P, and the transfer vehicle is changed. become a user who switches to As a result, it is possible to prevent a user who has boarded earlier from getting off the train for a user who has boarded later. In addition, user's dissatisfaction due to stopover can be eliminated. If there are three or more users riding in the shared vehicle, the users who will switch to the transfer vehicle are specified in order from the user who boarded the shared vehicle latest.

The shared vehicle management device 100 identifies a transfer vehicle by the following method as an example of a transfer vehicle identification method. The shared vehicle management device 100 identifies, as candidate vehicles for a transfer vehicle, a shared vehicle that travels along a travel route at or around the drop-off position of the user to be transferred. If there are a plurality of candidate vehicles, the vehicle closest to the current position of the shared vehicle X is identified as the transfer vehicle. However, when specifying the transfer vehicle based on the distance between the shared vehicle Vn and the shared vehicle X, the distance from the current position of the candidate vehicle to the desired destination (drop-off position) of the transfer target user is The shared vehicle management device 100 specifies a transfer vehicle after excluding a vehicle shorter than the distance from the current position of the vehicle to the desired destination (drop-off position) of the transfer target user from the candidate vehicles.

In the example of FIG. 8 , the shared vehicle management device 100 identifies the shared vehicle Vn that travels along the travel route at or around the drop-off position B′ of the user Q as a transfer vehicle candidate vehicle. The shared vehicle Y is traveling along the travel route Rb. A user R riding in a shared vehicle Y desires the position C' as the alighting position. The travel route Rb is a route that travels from the current position of the shared vehicle Y through intersections d, g, h, e, c, and f in this order. Traveling route Rb passes through drop-off positions B' and C'.

In the example of FIG. 8, since the user Q's drop-off position B' is on the traveling route Rb of the shared vehicle Y, the shared vehicle management device 100 identifies the shared vehicle Y as a candidate vehicle for the transfer vehicle. The shared vehicle Y is the closest vehicle to the current position of the shared vehicle X. Further, the distance from the current position of the shared vehicle Y to the destination of the user Q (drop-off position B') is longer than the distance from the current position of the shared vehicle X to the destination of the user Q (drop-off position B'). Therefore, the shared vehicle management device 100 identifies the shared vehicle Y as the transfer vehicle.

That is, in the present embodiment, the shared vehicle closest to the current position of the shared vehicle X is specified as the transfer vehicle from among the plurality of shared vehicles Vn. As a result, it is possible to prevent the transfer vehicle from making a detour to pick up the user Q, and prevent the scheduled alighting times of the users Q and R from being delayed. Further, in the present embodiment, a shared vehicle Y whose drop-off position B' of the user Q is on the traveling route of the shared vehicle Vn is specified as a transfer vehicle. As a result, the user Q shares the transfer vehicle with the user R, thereby preventing the user R from being delayed due to the change in the traveling route of the transfer vehicle.

Unlike the example of FIG. 8, while the shared vehicle X is traveling toward the intersection d (the state shown in FIG. 7), the shared vehicle Y, which is a candidate for a transfer vehicle, has already passed the intersection d and is heading toward the intersection g. Assume that the vehicle was running In such a case, the distance from the current position of the shared vehicle Y to the drop-off position B' of the user Q is shorter than the distance from the current position of the shared vehicle X to the drop-off position B' of the user Q. In order for the shared vehicle Y to accept the transfer from the shared vehicle X, the shared vehicle Y needs to make a U-turn on the traveling route Rb and return to the intersection d. In this embodiment, in order to prevent a situation in which the shared vehicle Y makes a U-turn and accepts the transfer of the user, the distance from the current position of the shared vehicle Y to the destination of the user Q is set to be the distance from the current position of the shared vehicle X to the user Q Shared vehicles that are shorter than the distance to the destination are excluded from candidates for transfer vehicles. As a result, the scheduled alighting time of the user (user R in the example of FIG. 8) who has already boarded the transfer vehicle is prevented while preventing the transfer vehicle from spending unnecessary travel time to pick up the user to be transferred. can be prevented from being delayed.

The shared vehicle management device 100 identifies the transfer position by the following method as an example of the method of identifying the transfer position. The shared vehicle management device 100 identifies transfer candidate positions at which the transfer target user transfers from the shared vehicle to the transfer vehicle based on the current position of the shared vehicle and the current position of the transfer vehicle. Before the transfer of vehicles, the travel route of the shared vehicle and the travel route of the transfer vehicle are determined. The shared vehicle management device 100 identifies, as a transfer candidate position, a point at which the mutual travel routes intersect or a point at which the mutual travel routes approach each other. It should be noted that the transfer candidate position does not necessarily have to be a point where the stop point of the shared vehicle and the stop point of the transfer vehicle are the same, and it is sufficient if the stop positions of the two vehicles are close to each other.

The shared vehicle management device 100 calculates the waiting time at the transfer candidate position based on the average speed of the shared vehicle and the average speed of the transfer vehicle. When the shared vehicle arrives at the boarding candidate position before the transfer vehicle, the waiting time is the time during which the user who is the target of the shared ride waits for the arrival of the transfer vehicle at the transfer candidate point. On the other hand, when the transfer vehicle arrives at the boarding candidate position earlier than the shared vehicle, the waiting time is the time the transfer vehicle waits for the arrival of the shared vehicle at the transfer candidate point. The shared vehicle management device 100 sets the transfer candidate position with the shortest waiting time as the transfer position.

A method of setting the transfer position will be described using the example of FIG. 8 . In the example of FIG. 8, since the traveling route Ra of the shared vehicle X and the traveling route Rb of the shared vehicle Y overlap at the intersection d, the position of the intersection d is specified as the transfer candidate position. Next, the shared vehicle management device 100 calculates the estimated arrival time of the shared vehicle X arriving at the intersection d based on the current position of the shared vehicle X and the average speed from the current position to the intersection d. The shared vehicle management device 100 calculates the estimated arrival time of the shared vehicle Y arriving at the intersection d based on the current position of the shared vehicle Y and the average speed from the current position to the intersection d. In the example of FIG. 8, the shared vehicle X and the shared vehicle Y arrive at the intersection d at approximately the same time, so the shared vehicle management device 100 sets the position of the intersection d as the transfer position.

After the transfer vehicle is specified and the transfer position is set, the shared vehicle management device 100 updates the travel plan of the shared vehicle and the travel plan of the transfer vehicle after the sharing cancellation. In the example of FIG. 8, after the shared vehicle X has dropped off the user Q at the intersection d, only the user P has boarded the shared vehicle X. The shared vehicle management device 100 calculates a travel route that allows the user P to reach the drop-off position A' in the shortest time based on the current position of the vehicle, current traffic information, and user P's desired conditions. In the example of FIG. 8, after the user Q gets off at the intersection d, the travel route is changed to the travel route Rc that travels from the intersection d to the intersections a, b, and c in order, and has the position A' as the destination. . Since the drop-off position B' of the user Q is located on the travel route of the shared vehicle Y, the travel route Rb of the shared vehicle Y is not changed.

After the travel route of the shared vehicle and the travel route of the transfer vehicle after the cancellation of the shared ride are updated, the shared vehicle management device 100 calculates the estimated time of arrival at the drop-off position based on the updated travel route. The estimated arrival time calculation process is executed before the shared vehicle and the transfer vehicle arrive at the transfer position.

First, the estimated arrival time of the shared vehicle of the transfer vehicle will be described. The shared vehicle management device 100 calculates the traveling time from the current position of the shared vehicle to the transfer position (hereinafter also referred to as the first traveling time) based on the current position of the shared vehicle, the transfer position, and the vehicle speed of the shared vehicle. . The vehicle speed of the ride-sharing vehicle may be, for example, the average speed from the current position to the transfer position. The shared vehicle management device 100 calculates the travel time from the current position of the transfer vehicle to the transfer position (hereinafter also referred to as the second travel time) based on the current position of the transfer vehicle, the transfer position, and the vehicle speed of the transfer vehicle. . The vehicle speed of the transfer vehicle may be, for example, the average speed from the current position to the transfer position. The shared vehicle management device 100 calculates the travel time from the transfer position to the alighting position (hereinafter also referred to as a third travel time) based on the transfer position, the alighting position of the user getting on the transfer vehicle, and the vehicle speed of the transfer vehicle. . Then, the shared vehicle management device 100 calculates the estimated arrival time of the transfer vehicle based on the first travel time, the second travel time, and the third travel time. Specifically, when the shared vehicle arrives at the transfer position before the transfer vehicle, the shared vehicle management device 100 adds the first travel time and the third travel time to the current travel time. By adding this to the time, the estimated time of arrival at the drop-off position is calculated. On the other hand, when the transfer vehicle arrives at the transfer position earlier than the shared vehicle, the shared vehicle management device 100 adds the travel time obtained by adding the second travel time and the third travel time to the current time. By doing so, the estimated time of arrival at the drop-off position is calculated.

Next, the estimated arrival time of the shared vehicle of the shared vehicle will be described. The shared vehicle management device 100 calculates the first travel time and the second travel time in the same manner as described above. The shared vehicle management device 100 determines the traveling time from the transfer position to the alighting position (hereinafter also referred to as the fourth traveling time) based on the transfer position, the user's exit position remaining in the vehicle after the cancellation of the shared ride, and the vehicle speed after the cancellation of the shared ride. ) is calculated. Then, the shared vehicle management device 100 calculates the estimated arrival time of the shared vehicle based on the first travel time, the second travel time, and the fourth travel time. Specifically, when the shared vehicle arrives at the transfer position before the transfer vehicle, the shared vehicle management device 100 sets the travel time obtained by adding the first travel time and the fourth travel time to the current travel time. By adding this to the time, the estimated time of arrival at the drop-off position is calculated. On the other hand, when the transfer vehicle arrives at the transfer position before the shared vehicle, the shared vehicle management device 100 further adds the travel time obtained by adding the second travel time and the fourth travel time to the current time. By doing so, the estimated time of arrival at the drop-off position is calculated.

After calculating the travel route and the estimated arrival time, the shared vehicle management device 100 updates the travel plan according to the calculation result. Then, the shared vehicle management device 100 notifies the user riding in the shared vehicle and the user riding in the transfer vehicle of the updated travel plan.

Taking another specific example, transfer of shared vehicles Vn will be described. FIG. 9 is a conceptual diagram for explaining the updated travel route of the shared vehicle and the travel route of the transfer vehicle. The desired conditions of the users P and Q, the traveling route Ra of the shared vehicle X, and the road on which the delay event occurs are the same as in the examples of FIGS. The traveling route Rb of the shared vehicle Y is different from the examples shown in FIGS. 6 to 8, and is a route in which the shared vehicle Y travels from the intersection j to the intersections g, h, and e in order and arrives at the drop-off position C'.

In the example of FIG. 9, the shared vehicle X and the shared vehicle Y arrive at the intersection g at approximately the same time, so the shared vehicle management device 100 sets the position of the intersection g as the transfer position. After the user Q gets off at the intersection g, the shared vehicle X travels with only the user P on board. Therefore, the traveling route of the shared vehicle X after the cancellation of the shared vehicle travels in the order of the intersections g, h, i, f, and c while avoiding the route including the delay event (the route between the intersection g and the intersection e). The route is changed to a route with A' as the destination. After boarding the user Q, the shared vehicle Y travels without changing the travel route, disembarks the user Q at the disembarking position B', and then travels along a route that disembarks the user R at the disembarking position C'. .

Taking another specific example, transfer of shared vehicles Vn will be described. FIG. 10 is a conceptual diagram for explaining the updated travel route of the shared vehicle and the travel route of the transfer vehicle. The desired conditions of users P and Q and roads on which delay events occur are the same as in the examples of FIGS. The traveling route Ra of the shared vehicle X is different from the examples shown in FIGS. 6 to 8, starting from the departure point S and traveling in the order of intersections d, a, and b. The traveling route Rb of the shared vehicle Y is a route that starts from the intersection b, travels through the intersection e, and reaches the drop-off position C'.

In the example of FIG. 10, the shared vehicle X and the shared vehicle Y arrive at the intersection b at approximately the same time, so the shared vehicle management device 100 sets the position of the intersection b as the transfer position. After dropping off the user Q at the intersection b, the shared vehicle X travels with only the user P on board. Therefore, the traveling route of the shared vehicle X after the cancellation of the carpooling is the shortest route from the intersection b to the drop-off position A', and is a traveling route that passes through the intersection c from the intersection b and arrives at the drop-off position A'. Be changed. After boarding the user Q, the shared vehicle Y travels without changing the travel route, disembarks the user Q at the disembarking position B', and then travels along a route that disembarks the user R at the disembarking position C'. .

When a user is on board the shared vehicle Vn, the shared vehicle management device 100 repeatedly executes the control flow shown in FIG. 5 to keep the shared vehicle Vn running. On the other hand, when the user gets off at the drop-off position and there is no user boarding the shared vehicle, the shared vehicle Vn travels to the vehicle station.

As described above, in this embodiment, desired conditions are acquired from each of a plurality of users, shared vehicles are specified from among a plurality of shared vehicles based on the desired conditions, and based on the desired conditions, each user goes to the drop-off position desired by each user. The estimated time of arrival and the travel route of the shared vehicle are calculated, and traffic information that affects travel on the travel route is acquired. Predict whether or not a delay event that causes a delay with respect to the estimated arrival time will occur while the user to be shared is riding in the vehicle, based on the current position of the vehicle and traffic information. When it is predicted that this will occur, a transfer vehicle is identified from among the plurality of shared vehicles, and the second user is notified that the estimated arrival time will be delayed and information regarding the transfer vehicle. The plurality of users includes at least a first user and a second user, and the first user gets on the vehicle to be shared before the second user. The drop-off position includes a first drop-off position desired by the first user and a second drop-off position desired by the second user. The estimated time of arrival includes the estimated time of arrival at the first drop-off position and the estimated time of arrival at the second drop-off position. The boarding vehicle corresponds to a shared vehicle or a shared vehicle after cancellation of shared riding.

As a result, for example, even if a delay event that deviates from the past congestion occurrence probability curve occurs during carpooling, it is possible to prevent the estimated arrival time from being greatly delayed. In addition, since the transfer vehicle is set on the server side, it is possible to automatically set the transfer point, which is conventionally determined by communication between the driver and the user, and provide it to the user. As a result, a safer and more convenient system can be constructed.

Further, in this embodiment, based on the current position of the boarding vehicle and the current position of the transfer vehicle, the second user sets the transfer position at which the second user transfers from the boarding vehicle to the transfer vehicle, and notifies the second user of the transfer position. Thereby, the second user can grasp the transfer position. Moreover, the waiting time of the second user or the transfer vehicle at the transfer position can be shortened.

Further, in the present embodiment, the estimated arrival time of the transfer vehicle to the second drop-off position is calculated based on the first travel time, the second travel time, and the third travel time, and the estimated arrival time to the second drop-off position is calculated. Notify the second user. Thereby, the second user can grasp the estimated time of arrival at the second get-off position after changing trains.

Further, in the present embodiment, the estimated arrival time of the boarding vehicle at the first drop-off position is calculated based on the first travel time, the second travel time, and the fourth travel time, and the estimated arrival time at the first drop-off position is calculated as the first expected arrival time. Notify 1 user. Thereby, the first user can grasp the estimated time of arrival at the first get-off position after the transfer is canceled.

Further, in the present embodiment, shared vehicles located around the current position of the boarding vehicle are identified as transfer vehicles. Thereby, the waiting time of the second user or the transfer vehicle at the transfer position can be shortened.

Further, in the present embodiment, a shared vehicle having a second drop-off position on the travel route or a shared vehicle having a second drop-off position around the travel route is specified as a transfer vehicle. This prevents the transfer vehicle from making a detour to pick up the second user, and suppresses delays in the scheduled arrival times of the user and the second user riding in the transfer vehicle.

Further, in the present embodiment, among the plurality of shared vehicles, the shared vehicle having the shortest distance from the current position of the shared vehicle to the current position of the boarding vehicle is specified as the transfer vehicle. Thereby, the waiting time of the second user or the transfer vehicle at the transfer position can be shortened.

Further, in the present embodiment, a shared vehicle having a long distance from the current position of the shared vehicle to the second drop-off position is specified as the transfer vehicle. As a result, it is possible to prevent a situation in which the shared vehicle Y makes a U-turn and accepts the transfer of the second user.

Further, in the present embodiment, based on the current position of the boarding vehicle and the current position of the transfer vehicle, a transfer candidate position where the second user transfers from the boarding vehicle to the transfer vehicle is specified, and the transfer vehicle waits for the arrival of the boarding vehicle at the transfer candidate position. A waiting time to wait is calculated for each of a plurality of transfer candidate positions, and a transfer candidate position having the shortest waiting time is set as a transfer position from among the plurality of transfer candidate positions. Thereby, the waiting time of the transfer vehicle at the transfer position can be shortened.

Further, in the present embodiment, transfer candidate positions are specified based on the current position of the boarding vehicle and the current position of the transfer vehicle, and the waiting time for the second user to wait for the arrival of the transfer vehicle at the transfer candidate position is determined by a plurality of transfer candidate positions. A transfer candidate position with the shortest waiting time is set as a transfer position from among a plurality of transfer candidate positions. Thereby, the second user's waiting time at the transfer position can be shortened.

In addition, in the present embodiment, a user who changes to a transfer vehicle is specified by prioritizing a user who has a lower boarding order for the boarding vehicle. As a result, it is possible to prevent a user who has boarded earlier from getting off the train for a user who has boarded later. In addition, user's dissatisfaction due to stopover can be eliminated.

As a modification of the present embodiment, a position suitable for stopping the transfer vehicle may be set as the transfer position based on the road information. For example, if the width of the road is narrow, it may not be possible to safely stop the carpool vehicle. Therefore, the shared vehicle management device 100 extracts wide roads, roads on which parking and stopping of vehicles are permitted, etc. from the road information, and sets transfer positions on the extracted roads. Thereby, an appropriate transfer position can be secured.

As a modification of the present embodiment, the shared vehicle management device 100 may set, as the current boarding position, a position set in the past as a transfer position or an alighting position. If there is a track record of use as the user's boarding position or alighting position, the shared vehicle Vn can be operated safely by setting the transfer position at the same point. When the user's boarding position or drop-off position is set, the shared vehicle management device 100 may store the position information of the boarding position or the drop-off position in the database 30 as a record.

As a modification of the present embodiment, the shared vehicle management device 100 may set transfer positions based on weather information. For example, on a rainy or snowy day, there is a possibility that a transfer position cannot be secured safely due to puddles, frozen road surfaces, or the like. The shared vehicle management device 100 identifies in advance locations where puddles and road surface freezing are likely to occur, based on the road shape and the like. Then, when there is a possibility of rain or snow based on the weather information, the shared vehicle management device 100 excludes places where puddles and road surface freezing are likely to occur from the transfer candidate positions. As a result, the shared vehicle Vn can be operated safely.
