Description

The present invention relates to an information management method and an information management device.

There is known a vehicle allocation management method for selecting and determining an appropriate operation route of a vehicle when there is a transfer request from another customer while the vehicle is transferring a customer or the like. This vehicle allocation management method calculates the estimated time required to complete the transfer of all passengers from the current location, calculated based on road traffic information, when a new customer transfer request is made to the vehicle being transferred. The minimum vehicle operation route is selected using a computer. In addition, when there is a transfer request from a customer, the operation route is selected by the above operation route selection method for vehicles that are transferring customers, and for vehicles that are not transferring customers, the vehicle goes from the current location to the transfer departure point. The operation route that minimizes the estimated travel time to the transfer destination is selected, and the vehicle that minimizes the increase in the estimated travel time from the beginning is assigned to the transfer request from these selected operation routes ( Patent Document 1).

Japanese Unexamined Patent Publication No. 2002-183892

However, since the above-mentioned vehicle allocation management method does not consider the situation after all passengers have boarded the vehicle, for example, when an event occurs in which the traveling time becomes long after the passengers have boarded, the disembarkation position. There is a problem that the arrival time to arrive at is significantly delayed from the arrival time expected by the customer.

An object to be solved by the present invention is to provide an information management method and an information management device capable of preventing a significant delay in the arrival time arriving at the disembarkation position after a plurality of users ride together.

The present invention obtains desired conditions from a plurality of users, identifies a shared vehicle from a plurality of shared vehicles based on the desired conditions, and based on the desired conditions, arrives at the desired disembarkation position of each user and shares the vehicle. Each vehicle's travel route is calculated, and traffic information that affects the travel on the travel route is acquired. While multiple users are boarding the boarding vehicle, based on the current position and traffic information of the boarding vehicle, it is predicted whether or not a delay event that causes a delay will occur with respect to the estimated time of arrival, and the delay event will occur. If it is predicted that the transfer vehicle will be identified from among the plurality of shared vehicles, the estimated time of arrival will be delayed, and the user will be notified of the information regarding the transfer vehicle to solve the above-mentioned problems.

The present invention can prevent the arrival time of the shared vehicle from arriving at the user's disembarkation position from being significantly delayed.

As a result, 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.

Further, the control device 230 notifies the user of the information transmitted from the shared vehicle management device 100 by using a display, a speaker, or the like (not shown). In the present embodiment, the control device 230 receives information about a user who wants to ride in the shared vehicle Vn from the shared vehicle management device 100, and notifies the user. The carpooling of the present embodiment means that a plurality of people ride together on one shared vehicle, and for example, it means that other people ride on one shared vehicle. In the following description, when a plurality of users are riding in a 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 so as to travel along the traveling route transmitted from the shared vehicle management device 100. When the shared vehicle Vn does not have the 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. Each includes a communication device 20 capable of communicating with each other, and a database 30 for storing information received by the communication device 20, information on each shared vehicle Vn, and the like.

The database 30 stores the shared vehicle information 31, the usage request 32 received from the user, the map information 33, the user information 34, and the 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, power remaining 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 of the shared vehicle Vn input by each user via the user terminal device 400A. The usage request 32 includes the user's ID information, the ID information of the shared vehicle Vn to be used by the user, the information on the user's current position, the boarding position (departure point) set by the user, the disembarkation position (destination), and the boarding. Information indicating the scheduled time (scheduled departure time), scheduled disembarkation time (scheduled arrival time), etc. is included. The scheduled boarding time and the scheduled disembarking time may each have a time range. For example, if the user wants to arrive at the specified disembarkation position between 10:30 am and 11:30 am, the estimated time of arrival is a time with a range of about 30 minutes centered on 11:00 am. Indicated by. Similarly, the scheduled departure time is also indicated by a time having 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, information on the structure of the building indicating the number of floors of the building, the passage of the building, the entrance / exit of the building, and the like. Further, the map information 33 includes, for example, information about each station such as position information of each station, facility information around each station, traffic conditions around each station, and usage status 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 on the current positions of all users. For example, the communication device 20 receives the current position information of each user from the user terminal device 400A of each user at predetermined periods, so that the current position information of each user can be stored in the user information 34.

The traffic information 35 is information that affects the traveling of the shared vehicle Vn, such as traffic congestion information and traffic regulation information. Traffic information is acquired from a system that manages road traffic information, such as VICS (registered trademark). FIG. 2 is a graph schematically showing the probability of daily traffic congestion on a certain road. In the example of FIG. 2, the probability of occurrence of traffic congestion is high around 7:00 and 18:00. The database 30 stores the probability of congestion on each road as traffic information 35 while associating it with a combination of weekdays, holidays, weather, and the like. The traffic information 35 is not limited to the probability of occurrence of traffic congestion as shown in FIG. 2, and may be indicated by, for example, the number of occurrences of traffic congestion.

As shown in FIG. 1, the control device 10 of the shared vehicle management device 100 of the present embodiment has a ROM (Read Only Memory) 12 in which a program for executing a process for managing and operating the car sharing system is stored, and the ROM (Read Only Memory) 12. By executing the program stored in the ROM 12, the CPU (Central Processing Unit) 11 as an operating circuit that functions as the shared vehicle management device 100 and the RAM (Random Access Memory) 13 that functions as an accessible storage device are provided. Be prepared.

An example of the form of car sharing will be described with reference to FIG. FIG. 3 is a schematic diagram showing an example of a method in which the user U1 uses the shared vehicle V1 in the shared vehicle management system 1 of the present embodiment. FIG. 3 shows a scene in which the user U1 tries to move from the departure place P1 set by the user U1 to the destination P2 by using the shared vehicle V1 by using the user terminal device 400A.

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 a desired condition for the user U1 to use the shared vehicle. It is transmitted from the device 400A to the shared vehicle management device 100.

The shared vehicle management device 100 moves to the departure point P1 and transmits a movement command for picking up the user U1 to the shared vehicle V1 selected based on the desired conditions. 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. Upon receiving the movement command from the shared vehicle management device 100, the shared vehicle V1 automatically travels to the departure 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 path 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 from the destination P2 to a station within a predetermined range.

In the present embodiment, the user can set an arbitrary point such as a railway station or a commercial facility as a departure place and a destination.

In the scene shown in FIG. 3, the user U2 is a user who can use the shared vehicle V1 in the same manner as the user U1. For example, when the car sharing system is a user-registered member-only system, both user U1 and user U2 are user-registered members. The user U2 operates the user terminal device 400B and transmits desired conditions to the shared vehicle management device 100. The user U2 receives from the shared vehicle management device 100 information including a travel plan of the shared vehicle V1 and information for confirming whether or not a carpool is desired by the user terminal device 400B. The travel plan includes a travel route R2 for carpooling. 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 that the shared vehicle V1 is used for carpooling.

The vehicle management device 100 changes the travel plan from the travel route R1 without carpooling to the travel route R2 with carpooling in order to allow the shared vehicle V1 to be shared between the user U1 and the user U2. The estimated time of arrival at the destination of the user U1 is delayed due to the change of the travel route, but if the estimated time of arrival is within the allowable range of the user U1, the vehicle management device 100 determines that the shared riding 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, the control process of the shared vehicle management device 100 will be described. FIG. 4 is a flowchart showing a control flow by the control device 10 of the shared vehicle management device 100.

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

The desired boarding time and the desired disembarking time are not limited to specific times, and may be specified in a time zone such as 8:00 am to 9:00 am. The desired condition does not necessarily have to include the desired boarding time or the desired disembarking time. For example, if the user wishes to board the shared vehicle 200 as soon as possible, the desired condition does not include the desired boarding time.

The desired time of disembarkation may be set within the range of time allowed for carpooling. As described above, when the travel route is changed by carpooling, the scheduled disembarkation time is later than the time until the travel route is changed. When the user specifies the desired disembarkation time in the time width, this time width is within an allowable range for the delay in the disembarkation time due to carpooling. That is, if the scheduled disembarkation time is delayed due to the shared ride, the shared ride is permitted if the changed scheduled disembarkation time is within the allowable range of the desired disembarkation time.

The desired conditions may include whether or not there is a desire for carpooling. For example, if the usage fee of the shared vehicle 200 at the time of carpooling is lower than the fee at the time of not carpooling, whether or not there is a desire for carpooling so that the user can request carpooling at the time of reservation application. Included in the desired conditions.

The desired conditions acquired from the user are stored in the database 30.

In step S102, the control device 10 identifies a vehicle that can be used from 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 conditions as a usable candidate vehicle. When the desired condition includes 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. When the control device 10 determines that 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 the shared vehicle Vn can be used, the control device 10 executes the control process in step S103.

In step S103, the control device 10 determines whether or not the carpooling condition is satisfied based on a plurality of desired conditions acquired from a plurality of users. The control device 10 identifies a user who can move from a desired disembarkation position to a disembarkation position as a carpool candidate user by performing a carpool on the shared vehicle Vn specified by the control process of step S102. When the desired condition includes the presence or absence of carpooling, the control device 10 identifies a carpooling candidate user from among the users who desire carpooling.

The control device 10 calculates the traveling route of the shared vehicle Vn when the user who is a carpool candidate is shared. The travel route is a route from the boarding position to the disembarking position of each user who is scheduled to board the shared vehicle Vn, including the user who is a carpool candidate. The control device 10 acquires the traffic information 35 from the database 30 and calculates the route with the shortest traveling time of the vehicle based on the traffic information. The control device 10 acquires information on the probability of occurrence of traffic congestion from the database 30 as shown in FIG. 2, and calculates a route that minimizes the traveling time while avoiding roads where traffic congestion is expected.

Next, the control device 10 calculates the scheduled boarding time and the scheduled disembarking time when the vehicle travels on the calculated travel route. The control device 10 calculates the scheduled boarding time and the scheduled disembarking time of each user scheduled to board by carpooling. The control device 10 determines whether or not the scheduled disembarkation time of the user who accepts the carpool is delayed by accepting the carpool. Further, when the scheduled disembarkation time is delayed by accepting the carpool, the control device 10 determines whether or not the delay of the estimated arrival time is within the allowable range. The permissible range is a time width specified by the user at the time of reservation of the shared vehicle Vn, and is indicated by desired conditions. Then, when the delay of the estimated time of arrival is within the allowable range, the control device 10 determines that the carpooling condition is satisfied. As a result, the control device 10 identifies the carpoolable user and the shared vehicle Vn (carpool vehicle Vn) based on the desired conditions of the plurality of users. On the other hand, when the delay of the estimated time of arrival is out of the allowable range, the control device 10 determines that the carpooling condition is satisfied.

The method for specifying the carpooling user and the method for specifying the carpooling vehicle are not limited to the above methods, and for example, the carpooling user or the vehicle may be specified by using the attribute information of the user such as gender and age. For example, when the user currently using the vehicle is a female, the control device 10 acquires the user information 34 when selecting the carpool candidate user, and the carpool candidate user is among the female users. May be specified.

When the carpooling condition is 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 to the user to be carpooled. Notify the driving plan and reservation completion. The carpooling target user is a user who rides in a carpooling vehicle, and includes a user on the synergistic side and a user on the carpooling side. The travel plan is indicated by a scheduled departure time from the boarding position desired by the user, an estimated arrival time at the disembarkation position desired by the user, a travel route, and the like. The reservation completion information is information such as a shared ride, a fare, etc., in addition to a notification that the reservation has been completed.

If the carpooling condition is not satisfied, in step S105, the control device 10 notifies the user of the travel plan and the completion of the reservation. The travel plan notified is a travel route when carpooling is not performed. Then, after notifying the user of the travel route and the reservation confirmation, the control process shown in FIG. 4 ends.

If there is no available shared vehicle in the control process of step S102, 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, the control device 10 notifies the user that the shared vehicle cannot be used under the desired conditions when the shared vehicle that matches the desired conditions cannot be specified. Then, the control process shown in FIG. 4 ends.

The above control flow is not limited to the case where the shared vehicle Vn is reserved before the shared ride target user gets on the shared vehicle, and the case where another user rides on the vehicle on which one user is riding. May be applied to. By carpooling a shared vehicle while riding, even if the scheduled disembarkation time of the user on board is delayed, if the scheduled disembarkation time is within the allowable range, the control device 10 determines that the carpooling condition is satisfied. .. Then, the control device 10 notifies the user on board of the changed travel plan. By confirming the notification, the user on board can recognize the scheduled disembarkation time after the change and the travel route after the change.

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

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

In the case of carpooling, the control device 10 acquires the current traffic information in step S202. In step S203, the control device 10 calculates the estimated time of arrival of the user to be shared based on the acquired current traffic information and the current position of the shared vehicle. The user to be carpooled corresponds to the user who is currently in the carpool vehicle. The estimated time of arrival calculated in step S203 may be later than the estimated time of arrival calculated at the time of reservation of the shared vehicle Vn, depending on the acquired current traffic information or the condition of the road currently traveling.

For example, in the traffic jam occurrence probability shown in FIG. 2, the traffic jam occurrence probability on a certain road is low, but when the traffic jam occurs due to a sudden event, the estimated arrival time is delayed. For example, when a sudden event (sudden event) such as an accident or construction affects the traveling time of a vehicle, it causes a delay with respect to the arrival time, so that it can be a delayed event. When the acquired current traffic information indicates the possibility of delay due to a sudden event, the control device 10 calculates the estimated time of arrival based on the acquired current traffic information, thereby arriving at the scheduled arrival time. You can grasp the time delay.

Further, even if the possibility of delay due to a sudden event is not reflected in the traffic information acquired from the outside, the control device 10 may acquire the traffic information from the current traveling state. For example, if the road ahead of the road currently being driven is congested due to construction work or the like, the current vehicle speed will be lower than the vehicle speed assumed at the time of calculating the travel route. Therefore, the control device 10 can acquire traffic information from the difference between the current traveling state of the vehicle and the traveling state expected when the total route is calculated. Then, the control device 10 can grasp the delay of the estimated arrival time by calculating the estimated arrival time from the current traveling state. The vehicle information of the running shared vehicle may be calculated from, for example, the position information of the shared vehicle.

In step S204, the control device 10 determines whether or not there is a delay in the calculated estimated time of arrival. The control device 10 determines whether or not there is a delay with respect to each estimated time of arrival of the users to be shared. If there is no delay in the calculated estimated time of arrival, 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 or not the delay in the estimated arrival time is out of the allowable range. If the estimated arrival time delay is within the permissible range, the control process shown in FIG. 5 ends. Then, when at least one delay among the delays of each estimated arrival time of the users to be shared is out of the allowable range, the control device 10 determines that the delay of the estimated arrival time is out of the allowable range.

In the present embodiment, the control device 10 is subject to carpooling based on the current position and traffic information of the shared vehicle Vn in a state where the user to be carpooled is in the carpooling vehicle by the control process from step S203 to step S205. It is predicted whether or not a delay event that causes a delay has occurred with respect to the scheduled time of disembarkation of the user. Then, when the occurrence of the delay event is predicted, the control device 10 determines that the delay of the estimated time of arrival of the user is out of the allowable range, and executes the control process of step S206.

In step S206, the control device 10 identifies the transfer vehicle. When at least one user among the users to be shared rides switches from the shared vehicle to another shared vehicle Vn, the shared vehicle Vn to be the transfer destination corresponds to the transfer vehicle.

For example, it is assumed that the first user gets on the carpool vehicle first and the second user gets on the carpool later. Then, it is assumed that a delay event occurs during the shared ride, and the delay of the scheduled disembarkation time of the first user is out of the allowable range of the scheduled disembarkation time determined at the time of reservation of the shared vehicle Vn. In such a case, in the present embodiment, the control for switching the second user from the shared vehicle to the transfer vehicle is executed. By switching to the transfer vehicle by the second user, the shared vehicle Vn after the second user gets off can travel on the shortest travel route with respect to the disembarkation position of the first user. Therefore, it is possible to suppress the delay of the scheduled disembarkation time of the first user.

The control device 10 identifies a transfer vehicle from a plurality of shared vehicles Vn based on the current position of the shared vehicle and the current position of the shared vehicle Vn. In the above example, among the plurality of shared vehicle Vn, the shared vehicle is scheduled to travel around the disembarkation position or the disembarkation position of the second user, and travels on the travel path of the shared vehicle or around the travel route of the shared vehicle. The vehicle Vn is specified as a transfer vehicle. That is, the control device 10 specifies the transfer vehicle so as to optimize the travel cost of the shared vehicle and the traveling cost of the transfer vehicle based on the desired conditions of the second user and the travel plan of the shared vehicle. The traveling cost is indicated by the traveling time or the traveling distance of the shared vehicle Vn. The method of specifying the transfer vehicle will be described later.

In step S207, the control device 10 sets the transfer position at which the user switches from the shared vehicle to the transfer vehicle. The point where the travel route of the transfer vehicle and the travel route of the shared vehicle intersect, or the point where 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 identifies a transfer candidate position that is a candidate for the transfer position, and the estimated time of arrival of the transfer vehicle to the transfer candidate position and the estimated time of arrival of the shared vehicle to the transfer candidate position. Is calculated, and the transfer candidate position with the best transfer efficiency is set as the transfer position. The method of setting the transfer position will be described later.

In step S208, the control device 10 calculates the travel plan of the transfer vehicle. The travel plan of the transfer vehicle is calculated based on the desired conditions of the transfer user. If another user is in the transfer vehicle at the time of transfer, or if the other user has reserved the use of the transfer vehicle, the control device 10 has changed according to the desired conditions of the other user. The travel plan of the transfer vehicle is calculated based on the user's desired conditions.

In step S209, the control device 10 calculates the travel plan of the shared vehicle Vn after the carpooling is canceled based on the user's desired condition. This user is a user who remains in the carpool vehicle after the carpool 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 carpool is canceled.

In step S211th, the control device 10 notifies the user of the updated travel plan. The control device 10 transmits information regarding 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 traveling plan by displaying information on the updated traveling plan on a display or the like. Further, the control device 10 may transmit information regarding the updated travel plan to the user terminal device 400. The updated travel plan notification may include a delay in estimated time of arrival if the carpool is continued. In addition, the notification to the user switching to the transfer vehicle may include information about the transfer vehicle, and the information about the transfer vehicle is information indicating that the system proposes the transfer of the vehicle, and the transfer position. Information, information on estimated time of arrival at the transfer position, vehicle information of the transfer vehicle, user information on the transfer vehicle, and the like. The information about the transfer vehicle is information to be notified to the user who continuously rides on the shared vehicle, including the change of the traveling route due to the transfer or the stop of the shared vehicle for the transfer. May be good. The user who received the notification confirmed that the scheduled disembarkation time would be delayed if the shared ride was continued, that the system suggested a transfer, and that the delay in the scheduled disembarkation time could be suppressed by making the transfer. can. Then, the control process shown in FIG. 5 ends.

Next, the control process of the control device 10 will be described with reference to a specific example. FIG. 6 is a conceptual diagram for explaining a traveling route of a shared vehicle before updating. FIG. 7 is a conceptual diagram for explaining the situation when a delay event occurs in the traveling route before the renewal of the shared vehicle. FIG. 8 is a conceptual diagram for explaining the travel route of the shared vehicle after the update and the travel route of the transfer vehicle.

The desired conditions of the user P and the user Q who are riding in a carpool will be described. The user P desires the position A as the boarding position and the position A'as the disembarking position (destination). The user Q desires the position B as the boarding position and the position B'as the disembarking position. Position A and position B are at the same point. The user P designates the desired boarding time at the boarding position A and the desired disembarking time at the disembarking position A'at desired times, respectively. Similarly, the user Q designates the desired boarding time at the boarding position B and the desired disembarking time at the disembarking position B'at desired times, respectively. Further, the shared vehicle X departs from the position S. User P rides on the shared vehicle X before user Q, and in the example of FIG. 6, user P and user Q ride on the shared vehicle X in a carpool, and the shared vehicle X approaches the intersection d. It is running like. The control device 10 passes through the target points including the boarding positions A and B and the disembarking positions A'and B'based on the desired conditions of the user P and the user Q, and the estimated arrival time of each target point is the user X. , Calculate the travel route Rа so as to match the desired time of Y. The travel route Rа shown in FIG. 6 is a route calculated by the control device 10, and the travel route Ra travels from the departure point S in the order of intersections d, g, e, f, and c, and reaches the destination A'. It is a route to be. Further, the traveling route Ra passes through the boarding positions A and B and the disembarking positions A'and B'.

The shared vehicle management device 100 communicates with the shared vehicle X while the shared vehicle X is traveling, and acquires information on the current position of the shared vehicle X. Further, the shared vehicle management device 100 acquires traffic information that affects the traveling of the shared vehicle X. The traffic information is congestion information occurring on the traveling route Ra and prediction information of congestion occurring on the traveling route Ra. 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 disembarkation positions A'and B') based on the acquired traffic information and the current position of the shared vehicle X. The shared vehicle management device 100 compares the calculated estimated arrival time with the estimated arrival time when the reservation of the shared vehicle X is confirmed, and determines whether or not an event causing a delay with respect to the estimated arrival time has occurred. Predict.

In the example of FIG. 7, a delay event such as traffic congestion occurs between the intersection g and the intersection e. When a delay event occurs between the intersection g and the intersection e, the disembarkation position B'is between the intersection g and the intersection e. Therefore, when the shared vehicle X travels on the travel path Ra, the disembarkation position B' The arrival time at'is delayed. In addition, the arrival time at the disembarkation position A'is also delayed.

In the present embodiment, as shown in the example of FIG. 7, when the delay of the estimated arrival time of the shared users P and Q is out of the allowable range, the user Q is transferred from the shared vehicle X to another shared vehicle. Identify the transfer vehicle to transfer. When the shared vehicle management device 100 identifies a user to be transferred, the shared vehicle management device 100 gives priority to a user who has a slower boarding order to the shared vehicle, and identifies a user who transfers to the transfer vehicle. In the example of FIG. 7, since the boarding order when the user Q gets on the shared vehicle X is slower than the boarding order when the user P gets on the shared vehicle X, the user Q has priority over the user P and the transfer vehicle. Become a user who switches to. As a result, it is possible to prevent the user who got on the train first from getting off the train for the user who got on the train later. In addition, the user's dissatisfaction due to getting off the train can be resolved. When there are three or more users in the carpool vehicle, the user who switches to the carpool vehicle is specified in order from the user who boarded the carpool vehicle the latest.

The shared vehicle management device 100 identifies the transfer vehicle by the following method as an example of the method of specifying the transfer vehicle. The shared vehicle management device 100 specifies a shared vehicle that travels around the disembarkation position or the disembarkation position of the user to be transferred as a travel route as a candidate vehicle for the transfer vehicle. When there are a plurality of candidate vehicles, the vehicle closest to the current position of the shared vehicle X is specified as a transfer vehicle. However, when specifying a 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 (disembarkation position) of the transfer target user is shared. The shared vehicle management device 100 specifies the transfer vehicle after excluding the vehicle shorter than the distance from the current position of the vehicle to the desired destination (disembarkation position) of the transfer target user from the candidate vehicles.

In the example of FIG. 8, the shared vehicle management device 100 specifies the shared vehicle Vn traveling around the disembarkation position B'or the disembarkation position B'of the user Q as a travel route as a candidate vehicle for the transfer vehicle. The shared vehicle Y is traveling on the travel path Rb. The user R who is on the shared vehicle Y desires the position C'as the disembarkation position. The travel route Rb is a route that travels in the order of intersections d, g, h, e, c, and f from the current position of the shared vehicle Y. The travel path Rb passes through the disembarkation positions B'and C'.

In the example of FIG. 8, since the disembarkation position B'of the user Q is on the travel path Rb of the shared vehicle Y, the shared vehicle management device 100 specifies the shared vehicle Y as a candidate vehicle for the transfer vehicle. The shared vehicle Y is the vehicle closest 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 (getting off position B') is longer than the distance from the current position of the shared vehicle X to the destination of the user Q (getting off position B'). Therefore, the shared vehicle management device 100 specifies the shared vehicle Y as a 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 in order to carry the user Q, and it is possible to prevent the scheduled disembarkation times of the users Q and R from being delayed. Further, in the present embodiment, the shared vehicle Y in which the disembarkation position B'of the user Q exists on the traveling path of the shared vehicle Vn is specified as a transfer vehicle. As a result, the user Q can ride in a carpool with the user R in the transfer vehicle, so that it is possible to prevent the delay of the scheduled disembarkation time of the user R due to the change of the traveling route of the transfer vehicle.

Unlike the example of FIG. 8, in a state where 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 headed for the intersection g. It is assumed that the vehicle was running. In such a case, the distance from the current position of the shared vehicle Y to the disembarking position B'of the user Q is shorter than the distance from the current position of the shared vehicle X to the disembarking 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 travel path Rb and return to the intersection d. In the present embodiment, in order to prevent the shared vehicle Y from making a U-turn and accepting the user's transfer, the distance from the current position of the shared vehicle Y to the destination of the user Q is 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 the candidates for transfer vehicles. As a result, the scheduled disembarkation time of the user who has already boarded the transfer vehicle (user R in the example of FIG. 8) is prevented from spending unnecessary traveling time for the transfer vehicle to carry the user to be transferred. Can be prevented from being delayed.

The shared vehicle management device 100 specifies the transfer position by the following method as an example of the method of specifying the transfer position. The shared vehicle management device 100 specifies a transfer candidate position at which the user to be transferred switches 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 changing vehicles, the traveling route of the carpool vehicle and the traveling route of the transfer vehicle are fixed. The shared vehicle management device 100 specifies a point where the traveling routes intersect with each other or a point where the traveling routes approach each other as a transfer candidate position. 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 coincide with each other, and it is sufficient that the stop positions 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 candidate boarding position before the transfer vehicle, the waiting time is the time for the user to be shared to wait for the arrival of the transfer vehicle at the transfer candidate point. On the other hand, when the transfer vehicle arrives at the carpool candidate position before the carpool vehicle, the waiting time is the time for the transfer vehicle to wait for the carpool vehicle to arrive at the transfer candidate point. The shared vehicle management device 100 sets the transfer candidate position having the shortest waiting time as the transfer position.

A method of setting the transfer position will be described with reference to the example of FIG. In the example of FIG. 8, since the travel path Ra of the shared vehicle X and the travel 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 time of arrival 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, since the shared vehicle X and the shared vehicle Y arrive at the intersection d at substantially the same time, the shared vehicle management device 100 sets the position of the intersection d to 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 carpooling is canceled. In the example of FIG. 8, after the shared vehicle X drops the user Q at the intersection d, only the user P is on the shared vehicle X. The shared vehicle management device 100 calculates a travel route that can reach the user P's disembarkation position A'in the shortest time based on the current position of the vehicle, the current traffic information, and the user P's desired conditions. In the example of FIG. 8, the travel route after getting off the user Q at the intersection d travels from the intersection d in the order of the intersections а, b, and c, and is changed to the travel route Rc with the position A'as the destination. .. Since the disembarkation position B'of the user Q is located on the travel path 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 are updated after the carpool is canceled, the shared vehicle management device 100 calculates the estimated time of arrival at the disembarkation position based on the updated travel route. The process of calculating the estimated time of arrival is executed before the shared vehicle and the transfer vehicle arrive at the transfer position.

First, the estimated time of arrival 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 shared vehicle may be, for example, the average speed from the current position to the transfer position. The shared vehicle management device 100 calculates the traveling time (hereinafter, also referred to as the second traveling time) from the current position of the transfer vehicle to the transfer position 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 traveling time from the transfer position to the disembarking position (hereinafter, also referred to as a third traveling time) based on the transfer position, the disembarkation position of the user who gets on the transfer vehicle, and the vehicle speed of the transfer vehicle. .. Then, the shared vehicle management device 100 calculates the estimated time of arrival of the transfer vehicle based on the first traveling time, the second traveling time, and the third traveling time. Specifically, when the shared vehicle arrives at the transfer position before the transfer vehicle, the shared vehicle management device 100 calculates the current travel time by adding the first travel time and the third travel time. By adding 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 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 time of arrival of the shared vehicle of the shared vehicle will be described. The shared vehicle management device 100 calculates the first traveling time and the second traveling time by the same method as described above. The shared vehicle management device 100 is based on the transfer position, the disembarkation position of the user remaining in the vehicle after the carpool cancellation, and the vehicle speed after the carpool cancellation, and the traveling time from the transfer position to the disembarking position (hereinafter, both the fourth traveling time). ) Is calculated. Then, the shared vehicle management device 100 calculates the estimated time of arrival of the shared vehicle based on the first traveling time, the second traveling time, and the fourth traveling time. Specifically, when the shared vehicle arrives at the transfer position before the transfer vehicle, the shared vehicle management device 100 calculates the current travel time by adding the first travel time and the fourth travel time. By adding 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 added to 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.

The shared vehicle management device 100 calculates the travel route and the estimated time of arrival, and then updates the travel plan according to the calculation result. Then, the shared vehicle management device 100 notifies the user who is in the shared vehicle and the user who is in the transfer vehicle of the updated travel plan.

The transfer of the shared vehicle Vn will be described with reference to another specific example. FIG. 9 is a conceptual diagram for explaining the travel route of the shared vehicle after the update 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 where the delay event occurs are the same as those in FIGS. 6 to 8. The travel route Rb of the shared vehicle Y is different from the example of FIGS. 6 to 8, and is a route that travels from the intersection j in the order of the intersections g, h, and e and arrives at the disembarkation position C'.

In the example of FIG. 9, since the shared vehicle X and the shared vehicle Y arrive at the intersection g at substantially the same time, the shared vehicle management device 100 sets the position of the intersection g to the transfer position. The shared vehicle X travels with only the user P on board after the user Q is dropped off at the intersection g. Therefore, the traveling route of the shared vehicle X after the carpooling is canceled is to travel in the order of 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), and the position. The route will be changed to A'as the destination. The shared vehicle Y travels on a route such that after boarding the user Q, the user Q travels without changing the travel route, the user Q disembarks at the disembarkation position B', and then the user R disembarks at the disembarkation position C'. ..

The transfer of the shared vehicle Vn will be described with reference to another specific example. FIG. 10 is a conceptual diagram for explaining the travel route of the shared vehicle after the update and the travel route of the transfer vehicle. The desired conditions of users P and Q and the road on which the delay event occurs are the same as in the examples of FIGS. 6 to 8. The travel route Ra of the shared vehicle X is different from the example of FIGS. 6 to 8, and the vehicle departs from the departure point S and travels in the order of intersections d, а, and b. The travel route Rb of the shared vehicle Y is a route that travels from the intersection b to the intersection e and arrives at the disembarkation position C'.

In the example of FIG. 10, since the shared vehicle X and the shared vehicle Y arrive at the intersection b at substantially the same time, the shared vehicle management device 100 sets the position of the intersection b at the transfer position. The shared vehicle X travels with only the user P on board after the user Q is dropped off at the intersection b. Therefore, the travel route of the shared vehicle X after the carpooling is canceled is such that the route is the shortest route from the intersection b to the disembarkation position A', passing through the intersection c from the intersection b and arriving at the disembarkation position A'. Be changed. The shared vehicle Y travels on a route such that after boarding the user Q, the user Q travels without changing the travel route, the user Q disembarks at the disembarkation position B', and then the user R disembarks at the disembarkation position C'. ..

When the user is on the shared vehicle Vn, the shared vehicle management device 100 keeps the shared vehicle Vn running while repeatedly executing the control flow shown in FIG. On the other hand, when the user gets off at the disembarkation position and there is no user who gets on the shared vehicle, the shared vehicle Vn travels to the vehicle station.

As described above, in the present embodiment, desired conditions are obtained from a plurality of users, a shared vehicle is specified from a plurality of shared vehicles based on the desired conditions, and the disembarkation position desired by each user is determined based on the desired conditions. The estimated time of arrival and the travel route of the shared vehicle are calculated respectively, and the traffic information that affects the travel on the travel route is acquired. Based on the current position and traffic information of the boarding vehicle, it is predicted whether or not a delay event that causes a delay will occur with respect to the estimated time of arrival while the user to be shared rides is boarding the boarding vehicle, and the delay event occurs. If it is predicted to occur, the transfer vehicle is identified from the plurality of shared vehicles, the estimated arrival time is delayed, and the second user is notified of the information regarding the transfer vehicle. The plurality of users include 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 disembarkation position includes a first disembarkation position desired by the first user and a second disembarkation position desired by the second user. The estimated time of arrival includes the estimated time of arrival at the first disembarkation position and the estimated time of arrival at the second disembarkation position. The carpool vehicle corresponds to a carpool vehicle or a shared vehicle after the carpool is canceled.

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 delay of the estimated arrival time from being significantly delayed. Further, since the transfer vehicle is set on the server side, the transfer point, which is conventionally determined by communication between the driver and the user, can be automatically set and provided to the user. As a result, a safer and more convenient system can be constructed.

Further, in the present embodiment, the second user sets the transfer position for transferring from the boarding vehicle to the transfer vehicle based on the current position of the boarding vehicle and the current position of the transfer vehicle, and notifies the second user of the transfer position. As a result, the second user can grasp the transfer position. In addition, 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 time of arrival of the transfer vehicle to the second disembarkation 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 disembarkation position is calculated. Notify the second user. As a result, the second user can grasp the estimated time of arrival at the second disembarkation position after the transfer.

Further, in the present embodiment, the estimated arrival time of the boarding vehicle at the first disembarkation 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 disembarkation position is set as the first. Notify one user. As a result, the first user can grasp the estimated time of arrival at the first disembarkation position after the transfer is canceled.

Further, in the present embodiment, a shared vehicle located around the current position of the boarding vehicle is specified as a transfer vehicle. As a result, 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 in which the second disembarkation position exists on the travel route or a shared vehicle in which the second disembarkation position exists in the vicinity of the travel route is specified as a transfer vehicle. As a result, it is possible to prevent the transfer vehicle from detouring to pick up the second user, and to prevent the user and the second user who are on the transfer vehicle from delaying their estimated arrival times.

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. As a result, the waiting time of the second user or the transfer vehicle at the transfer position can be shortened.

Further, in the present embodiment, the shared vehicle in which the distance from the current position of the shared vehicle to the second disembarkation position is long from the current position of the transfer vehicle to the disembarkation position is specified as the transfer vehicle. As a result, it is possible to prevent the shared vehicle Y from making a U-turn and accepting the transfer of the second user.

Further, in the present embodiment, the second user specifies the transfer candidate position for transferring from the boarding vehicle to the transfer vehicle based on the current position of the boarding vehicle and the current position of the transfer vehicle, and the transfer vehicle arrives at the transfer candidate position. The waiting time is calculated for each of the plurality of transfer candidate positions, and the transfer candidate position having the shortest waiting time is set as the transfer position among the plurality of transfer candidate positions. As a result, the waiting time of the transfer vehicle at the transfer position can be shortened.

Further, in the present embodiment, the transfer candidate position is 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 set to a plurality of transfer candidate positions. It is calculated for each transfer candidate position, and the transfer candidate position having the shortest waiting time is set as the transfer candidate position among the plurality of transfer candidate positions. As a result, the waiting time of the second user at the transfer position can be shortened.

Further, in the present embodiment, the user who has a late boarding order to the boarding vehicle is prioritized, and the user who switches to the transfer vehicle is specified. As a result, it is possible to prevent the user who got on the train first from getting off the train for the user who got on the train later. In addition, the user's dissatisfaction due to getting off the train can be resolved.

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 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 vehicles are allowed to park and stop, and the like from the road information, and sets a transfer position on the extracted roads. This makes it possible to secure an appropriate transfer position.

Further, as a modification of the present embodiment, the shared vehicle management device 100 may set a position previously set as a transfer position or a disembarkation position to the current boarding position. If the user has a track record of use as a boarding position or a disembarking position, the shared vehicle Vn can be safely operated by setting the transfer position at the same point. When the shared vehicle management device 100 is set as the boarding position or the disembarking position of the user, the position information of the boarding position or the disembarking position may be stored in the database 30 as a record.

Further, as a modification of the present embodiment, the shared vehicle management device 100 may set a transfer position based on weather information. For example, on rainy or snowy days, it may not be possible to safely secure a transfer position due to puddles, freezing of the road surface, or the like. The shared vehicle management device 100 specifies in advance a place where a puddle or a road surface freeze is likely to occur from the road shape or the like. Then, the shared vehicle management device 100 excludes a place where a puddle or a road surface freeze is likely to occur from the transfer candidate position when there is a possibility of rain or snow from the weather information. As a result, the shared vehicle Vn can be safely operated.
