Request points further include a boarding point, an alighting point, and a destination that are calculated on the basis of the user's preference. Request points are included in predetermined points for the vehicle allocation.

The boarding/alighting point determination apparatus100according to one or more embodiments of the present invention will be described below. The boarding/alighting point determination apparatus100according to one or more embodiments of the present invention constitutes a part of the vehicle allocation system1. The boarding/alighting point determination apparatus100exchanges information with the control apparatus200of a vehicle and the user terminal apparatus300. The boarding/alighting point determination apparatus100calculates the common point as a boarding point at which one or more users board a vehicle or an alighting point at which one or more users alight from the vehicle.

The boarding/alighting point determination apparatus100according to one or more embodiments of the present invention is a server configured on a communication network. The boarding/alighting point determination apparatus100determines a boarding point and/or an alighting point, creates a vehicle allocation plan, and generates an execution command for a vehicle allocation process. Separate processors may be equipped for creating the vehicle allocation plan and generating the execution command for the vehicle allocation process, but in the present example, a processor10of the boarding/alighting point determination apparatus100executes the vehicle allocation process in an integrated manner.

As illustrated inFIG. 1, the boarding/alighting point determination apparatus100according to one or more embodiments of the present invention includes the processor10, a communication device20, and an output device30. The communication device20exchanges information with the control apparatus200of a vehicle and/or the user terminal apparatus300. The output device30presents the calculation result as necessary.

The processor10of the boarding/alighting point determination apparatus100according to one or more embodiments of the present invention has a request acquisition function, a predetermined range setting function, a user specifying function, and a common point calculation function. The control device10according to one or more embodiments of the present invention executes each function by cooperation of software for achieving the above functions and the above-described hardware.

As an example,FIG. 2illustrates functional blocks of the processor10. As illustrated inFIG. 2, the processor10according to one or more embodiments of the present invention includes a request acquisition unit A1that acquires a request, a predetermined range setting unit A2that sets a predetermined range, a user specifying unit A3that specifies a user, a common point calculation unit A4that calculates a common point for boarding or alighting, a common point presentation unit A5that presents the common point, a confirmation unit A6that confirms an acceptance from a user, a common point setting unit A7that sets the common point, a route calculation unit A8that calculates a route, and an autonomous travel command unit A9that controls a vehicle to travel autonomously. Each unit of the processor10calculates an operation command for performing each of the above processes and transmits the command to the control apparatus200or user terminal apparatus300in which the calculated operation command is executed.

The vehicle allocation system1according to one or more embodiments of the present invention includes a plurality of vehicles and controls each vehicle to move to a predetermined point in response to the request from a user. Predetermined points include a boarding point or alighting point desired by a user or a current location or destination of a user.

The vehicle allocation system1may control a vehicle to move to a predetermined point on the basis of the request from a single user. This is a case in which a vehicle with no occupant (empty vehicle) moves to a request point of a user who desires boarding, on the basis of the request from the user. The vehicle allocation system1may control a vehicle to move to a predetermined point on the basis of the requests from a plurality of users. This is a case in which a plurality of users is allowed to board or a case in which a vehicle with one or more users already on board moves to another user's boarding point or alighting point (request point or common point). At each predetermined point at which one vehicle makes a stop during one trip, one or more users board or alight or two or more users board and alight.

The boarding/alighting point determination apparatus100, which is a server apparatus, at least temporarily stores vehicle information acquired from the control apparatuses200of a plurality of vehicles that can be targets of vehicle allocation. The vehicle information includes general information indicating a vehicle state managed by a vehicle, such as the positional information, traveling direction, vehicle speed, steering amount, remaining energy amount, door lock information, seat belt attachment/detachment information, seating information, and automated (autonomous) driving situation of the vehicle, which are associated with the identification information of the vehicle. The boarding/alighting point determination apparatus100stores information regarding vehicle allocation control, such as a request for vehicle allocation, an execution situation (progress information) of a vehicle allocation plan, the presence/absence and number of users on board, a boarding/alighting status (progress of boarding/alighting in the vehicle allocation plan), arrival at a predetermined point, and specifying of the next predetermined point. The information regarding the vehicle allocation control is associated with identification information of a vehicle and/or identification information of a user. The boarding/alighting point determination apparatus100stores the request from a user, past requests from the user, a past use history of the user, an attribute of the user, and a requirement from the user, which are associated with the identification information of the user.

Each function of the boarding/alighting point determination apparatus100according to one or more embodiments of the present invention will then be described along the control procedure.FIG. 3illustrates an example of a control procedure executed in the vehicle allocation system1including the boarding/alighting point determination apparatus100.

In step101, the processor10acquires the request from a user who desires the use of the vehicle allocation system. The request includes a request point, request date and time, user identification information, information for specifying a reserved vehicle, an attribute of the user, a requirement from the user, a preference of the user, a usage history of the user, a history of the boarding/alighting points of the user, etc.

Information included in a request will be described.

Request points include the current location of a user or a boarding point desired by the user. The current location is a point at which a user is located. It is convenient for a user that the current location and the boarding point are close to each other because the movement amount of the user is small. Request points include the destination of a user or an alighting point desired by the user to alight. The destination is a point at which a user having alighted finally accomplishes a purpose. It is convenient for a user that the destination and the alighting point are close to each other because the movement amount of the user is small. The request point may be one of a plurality of points including stop-off points (way points).

The request point may be represented by coordinate values such as latitude and longitude or may also be represented by identification information of a facility such as a stop or a station. The request point does not necessarily require positional information (coordinate values). The position in the identification information is acquired with reference to the map information123. The request in which the current location of a user is set as the request point is a requirement from the user who desires the vehicle allocation to the location at which the user is located (current location). The request in which the boarding point designated by a user is set as the request point is a requirement from the user who desires the vehicle allocation to a point desired by the user. The request in which the alighting point designated by a user is set as the request point is a requirement from the user who needs to alight at a point desired by the user.

Request points included in the requests for desired boarding include a boarding point desired by a user, the current location of the user, or a boarding point at which a user is expected to board. Information on the expected boarding point includes a preference of the user, a usage history of the user, and a history of past boarding points. The current location as the request point may be represented by a detection result of the position detection device340of the user terminal apparatus300. The current location detected by the position detection device340may be automatically transmitted at a predetermined cycle to the vehicle allocation system including the boarding/alighting point determination apparatus100via the communication device320. After boarding, the user is to alight. A request for alighting may be transmitted to the vehicle allocation system1together with the request for boarding.

Request points included in the requests for desired alighting include an alighting point desired by a user, the destination of a user, or an alighting point at which a user is expected to alight. Information on the expected alighting point includes a preference of the user, a usage history of the user, and a history of past alighting points. The destination as the request point may be represented by input information of a route search or the like input to the user terminal apparatus300or may also be represented by an estimation result based on the user's schedule or action history. The destination estimated by the processor310may be automatically transmitted to the vehicle allocation system1including the boarding/alighting point determination apparatus100via the communication device320.

The user identification information is information for specifying a user. The request date and time are the date and time at which the vehicle allocation is desired (the date and time at which the boarding is desired or the date and time at which the alighting is desired (the time slot in which the boarding is desired or the time slot in which the alighting is desired)). The information for specifying a vehicle is information for a user to specify a desired vehicle. Examples of the desired vehicle include those having functions that satisfy the needs of users, such as a vehicle that can accommodate a desired number of users, a vehicle that can store a suitcase, a vehicle that can store a wheelchair, and a vehicle that is equipped with a child seat.

Attributes of a user include the user's age, user's gender, user's preference, user's schedule, user's usage history, history of the user's boarding/alighting points, and the form of a baggage carried by the user (a suitcase, a luggage having a predetermined size or more, or a luggage having a predetermined length or more). The requirement from a user includes information as to whether to accept or refuse ride-sharing.

The requirement from a user includes a required matter regarding movement. The vehicle allocation plan is created with reference to the requirement from a user. In one or more embodiments of the present invention, the designation of a request point is received, but the point for a vehicle to actually pick up an occupant may be a common point different from the request point; therefore, a user may be required to move to the common point or move from the common point to a destination. The user can preliminarily provide a restriction on the required movement in the request. The restriction on movement can be designated as a restriction value on any of a distance, a movement time, a walking time, and an altitude difference. By including this restriction in the request, it is possible to refuse boarding or alighting at a common point that requires movement of a restriction value (such as a restriction distance) or more. When a restriction on movement is provided, the user is required to move within the restricted range, which the user sets for himself/herself, around the boarding or alighting.

For example, when boarding, the user can board at a common point to which the walking time is X minutes or less or the walking distance is a certain distance or less from the request point (the current location, a desired boarding point, or an expected boarding point) and at which the user can arrive along a route with an up-and-down slope (an altitude difference) of Y m or less. When alighting, the user can alight at a common point to which the walking time is X minutes or less or the walking distance is a certain distance or less from the request point (the destination, a desired alighting point, or an expected alighting point) and at which the user can arrive along a route with an up-and-down slope (an altitude difference) of Ym or less.

In step102, the processor10acquires a request point included in the request. Request points regarding the boarding include a desired boarding point, the current location, an expected point at which the user desires to board, and a point at which the user tends to board. Request points regarding the alighting include a desired alighting point, the destination, an expected point at which the user desires to alight, and a point at which the user tends to alight. The destination is a point to which the user moves after alighting.

The processor10can calculate and obtain the request point from information associated with the user included in the request. The processor10may calculate the user's boarding or alighting point from the user's schedule included in the request. The processor10may estimate a destination at which the user stops off from the user's preference included in the request and calculate a boarding or alighting point for reaching the destination. The processor10may estimate a destination at which the user stops off from the history of the user included in the request and calculate a boarding or alighting point for reaching the destination.

In step103, the processor10sets a predetermined range. The predetermined range is a range in which one trip (vehicle allocation service) for moving a vehicle is performed in response to the requests from users.

The predetermined range may be an area that is preliminarily set. A predetermined section may be defined as the predetermined range on the basis of the latitude and longitude (coordinates) on the map information123. For example, as illustrated inFIG. 4A, a predetermined range Q1may be set as a range that is preliminarily defined by (X2, Y2) in accordance with a mesh section of the map information123. The shape of the predetermined range is not limited. The shape of the predetermined range may be any of a polygon, a circle/ellipse, and a shape having an irregular outer edge. The scheme of defining the size of the predetermined range is not limited, but the predetermined range is set as a common-sense range so that a user (person) can access the predetermined point on foot. For example, in the case of a rectangular predetermined range, the size of the predetermined range may be 1 km square. By preliminarily defining the predetermined range, it is possible to reduce the load of a process of specifying a user. The position of a predetermined point of interesting (POI) may be employed as a reference point.

As illustrated inFIG. 4B, a predetermined range Q2(illustrated by a broken line) may be defined using a request point or the like as the reference point. For example, the predetermined range Q2corresponding to a user U1who made a vehicle allocation request may be set with reference to a request point PU1of the user U1. The predetermined range Q2may also be set as an area that includes a user range QU1based on the request point PU1of the user U1. For example, the predetermined range Q2may be set so as to include request points PU1and PU2(departure points such as the current location and the boarding point) of a plurality of users U1and U2who made the vehicle allocation requests. In the example illustrated in the figure, the predetermined range Q2is set as a circular area having a constant radius, for example, 500 m, around the request point PU1of the user U1who made the vehicle allocation request. Of course, the predetermined range Q2may be defined with reference to a request point PD1(desired alighting point) of a user D1who is to alight.

The request point of a user as a reference when setting the predetermined range Q2may be the request point of the user D1(on board) for whom execution of the request has already been started or may also be the request point of a user from whom a request is newly acquired. The range in which walking is possible is set using information on the route which is included in the map information123and along which walking is possible. The predetermined range Q2may be set as a range that can be reached within a predetermined time (e.g., within 5 minutes) from the request point (departure point) of the user U1or may also be set as an area including the user range QU1that can be reached on foot within 3 minutes. By setting the predetermined range Q2so as to include the request points, it is possible to create the vehicle allocation plan in which the predetermined points are set, including the boarding points/alighting points along the desires of users.

In a process of setting the predetermined range Q2on the basis of the request points, user ranges QU1and QU2may be set in accordance with the request points of respective users, and the predetermined range Q2may be set to include the user ranges QU1and QU2. In this operation, the predetermined range Q2may be set to include a user range (not illustrated) based on the request point PD1of the user D1who is to alight. When the predetermined range Q2is set from the user ranges QU1and QU2based on the request points, the attribute of each user included in the request is taken into account. That is, the user ranges QU1and QU2are set on the basis of the attributes of the users. When the attribute of the user U2is being an elderly person, a child, or a person with a child, carrying a large/heavy baggage, or having a handicap such as an injury, the size (diameter) of the user range QU2is set small. On the other hand, when the attribute of the user U1is not being an elderly person, a child, or a person with a child, carrying a small/light baggage, or having no handicap such as an injury, the size (diameter) of the user range QU1is set relatively large. By taking into account the attributes of users when setting a predetermined range Q, it is possible to create the vehicle allocation plan in which the predetermined points are set, including the boarding points/alighting points determined to give importance to the convenience of the users.

In step104, the processor10specifies a user who is expected to board/alight at a point included in the predetermined range. The processor10narrows down users who board the vehicle or alight from the vehicle within the predetermined range as the targets and attempts to make a vehicle allocation plan in which the narrowed-down users are allowed to board/alight. Points included in the predetermined range include a request point and a common point. When the predetermined range is set on the basis of a request point, users are specified on the basis of one or more request points. By specifying the users on the basis of the request points, it is possible to create the vehicle allocation plan in which the predetermined points are set, including the boarding points/alighting points along the desires of users.

Users targeted for the vehicle allocation plan are not limited to the users who board/alight within the predetermined range, and all the users who transmitted requests may be targeted.

In step105, the processor10calculates a common point at which a specified user boards/alights as the predetermined point. A single common point may be calculated or a plurality of common points may also be calculated.

The processor10may calculate a common point that is a point at which one user of specified users boards or alights. The common point in this case is a predetermined point at which the vehicle and the one user get together. The processor10may calculate a common point that is a point at which a plurality of users of specified users boards/alights. The common point in this case is a predetermined point at which the vehicle and the plurality of users get together. The plurality of users is allowed to board/alight at one common point; therefore, the number of stops can be reduced, and one trip time can be shortened when compared on the same route. By reducing the number of stops, it is possible to suppress the energy consumption, improve the fuel efficiency of the vehicle, and reduce the time required for passing from the first predetermined point to the last predetermined point in the vehicle allocation service.

Schemes of calculating a common point will then be described with reference toFIGS. 5A to 5D.

The processor10calculates the common point on the basis of the request point included in the request from a user. The common point may be the center or weighted center of an area that includes the request points of a plurality of users. When there is a place in which an evacuation area or the like is set in an area including the request points of a plurality of users (a place in which it is easy for the vehicle to park), the place is set as the common point. By calculating the common point on the basis of the request points, it is possible to create the vehicle allocation plan in which the common point is set along the desires of users.

As illustrated inFIG. 5A, the common point PC1may be a request point PB1of a user D1who is already on board and requests alighting. When the request point PB1is the common point, a user U2who requests boarding moves to the request point PB1which is the boarding point. When there is a plurality of users who request boarding or alighting, the common point may be the request point of a user who requested the vehicle allocation earlier or may also be the request point of a user who newly requested the vehicle allocation (later). When there is one user, that is, when there is one request point, a point near the request point is set as the common point. By setting the request point of a user as the common point, it is possible to create the vehicle allocation plan in which the common point is set along the desire of the user. Additionally or alternatively, when there is a place in which it is easy for the vehicle to park, such as a place in which an evacuation area or the like is set near the request point, the point of the place is set as the common point.

The common point PC1may be calculated as a point(s) at which a plurality of users of specified users boards (PB1) or alights (PD1). The common point in this case is a predetermined point at which the plurality of users gets together. The plurality of users is allowed to board or alight at one common point; therefore, the number of stops can be reduced, and one trip time can be shortened. By reducing the number of stops, it is possible to suppress the energy consumption, improve the fuel efficiency of the vehicle, and reduce the time required for passing from the first predetermined point to the last predetermined point in the vehicle allocation service. The same effects can be obtained also in the third to fifth schemes.

The processor10sets the common point to a point for which a determination is made that the access cost for a vehicle and the access cost for a user are equivalent. The access cost for a vehicle in this scheme is a cost calculated from the time required for the vehicle to reach an arbitrary point (common point). Arbitrary points include the common point. The access cost for a user is a cost calculated from the time required for the user to reach an arbitrary point (common point). Arbitrary points include the common point.

For an arbitrary point, the processor10calculates the access cost for a vehicle and the access cost for a user. The access cost regarding the arrival time of a vehicle is determined through referring to the map information123to calculate the distance to an arbitrary point (common point) that is set for calculation, acquiring the vehicle speed of the vehicle from the vehicle speed sensor62, and calculating the time required for arrival at the arbitrary point or the time of arrival at the arbitrary point. The vehicle speed may be a legal speed or a standard speed for each road stored in association with the road information122. The required time may be calculated with reference to traffic congestion information.

The distance for a user to reach an arbitrary point (common point) on foot may be determined by taking into account not only the length of a road in the map information123but also a specific position at which the user is located, such as the floor of a facility or the position in the facility. In a large facility, the distance (required time) to an exit is required depending on the position of the user and the floor number and may affect the distance (required time) to a predetermined point. The processor10calculates the floor number of the user and the distance to an exit of the facility using the altitude and position detected by the position detection device340of the user terminal apparatus300and adds the result to the access cost for the user. The map information123possesses not only the location of a facility but also floor maps of the facility. The processor refers to the map information123to calculate the distance from the current location of the user to an exit of the facility.

The access cost regarding the arrival time of a user is determined through referring to the map information123to calculate the distance from the current location to an arbitrary point (common point), reading the walking speed of a general pedestrian, which is preliminarily stored, and calculating the time until the user arrives at the arbitrary point or the time at which the user arrives at the arbitrary point. The access cost regarding the arrival time of a user may be affected by the attribute of the user. The processor10may calculate the access cost by setting the walking speed to be lower as the age of the user is a predetermined value (old age) or more and the age is higher. The processor10may also calculate the access cost by setting the walking speed to be lower as the age of the user is less than a predetermined value (child) and the age is lower. When the user carries a large baggage such as a suitcase, the processor10may calculate the access cost by setting the walking speed to be lower than when the user does not carry such a baggage.

The processor10sequentially sets an arbitrary point on the route as a provisional common point, obtains the route for a vehicle and the route for a user to the provisional common point, and calculates the time required for the vehicle to reach the common point along the route and the time required for the user to reach the common point along the route. A provisional common point having the smallest arrival time difference at the provisional common point is obtained as the common point to which the access cost for the vehicle and the access cost for the user are equivalent. It is preferred to preliminarily register provisional common points in the map information123. The provisional common points to be preliminarily set may be set by selecting points to which the access difficulty level, which represents the difficulty for the vehicle to make a stop, is less than a predetermined value (access cost is low).

The processor10compares the access cost for the vehicle with the access cost for the user. The processor10calculates, as the common point, an arbitrary point for which a determination is made that the access cost for the vehicle calculated from the time to the common point and the access cost for the user calculated from the time to the common point are equivalent, that is, an arbitrary point for which a determination is made that the arrival time difference at the common point is less than a predetermined value. This common point is the predetermined point to which the target vehicle to be allocated moves.

As illustrated inFIG. 5B, a common point PC1is calculated as the position at which a time TV1for a vehicle V1to reach the common point PC1is substantially equal to a time TU1for a user U1to reach the common point PC1. With reference to the calculated time under the condition that the time TV1and the time TU1are substantially equal, the vehicle V1moving and the user U1moving arrive at the common point PC1at approximately the same time. That is, this can prevent the vehicle V1from staying for a long time to wait for the user U1. By shortening the staying time of the vehicle V1to be allocated, it is possible to suppress the disturbance of the traffic flow due to the allocated vehicle being parked.

Although not illustrated, when it is not possible to calculate the common point PC1at which the vehicle V1and a plurality of users U1and U2arrive at the same time, the common point PC1may be calculated so that the arrival time TV1of the vehicle V1is substantially the same as the arrival time TU2of the user U2whose position is separated from the vehicle V1. If the common point is set as a point at which the vehicle V1and the user U1closer to the vehicle V1arrive at the same time, the vehicle V1has to wait for the arrival of the user U2, who is located at a position relatively far from the vehicle, after picking the user U1up. In such a case, the common point PC1is set as a point at which the vehicle V1arrives at the same time as the user U2located at a position relatively far from the vehicle. The user U1located closer to the vehicle is made to wait, but the staying time of the vehicle V1can be minimized and it is therefore possible to suppress the disturbance of the traffic flow due to the allocated vehicle being parked.

The processor10sets the common point to a point for which a determination is made that the access costs for a plurality of users are equivalent. The access cost for a user who desires to board is a cost calculated from the distance for the user to reach an arbitrary point (common point), the time for the user to reach the arbitrary point (common point), or the load for the user to reach the arbitrary point (common point). Arbitrary points include the common point. The access cost for a user who desires to alight is a cost calculated from the distance for the user to reach a destination (request point) from an arbitrary point (common point), the time for the user to reach the destination (request point) from the arbitrary point (common point), or the load for the user to reach the destination (request point) from the arbitrary point (common point).

For an arbitrary point, the processor10calculates the access costs for a plurality of users. The access cost for a user who requests boarding is a cost for the user to reach the common point from the current location, and the access cost for a user who requests alighting is a cost for the user to reach the destination from the common point.

As in the third scheme, the access cost regarding the arrival time of a user who requests boarding is determined by referring to the map information123to calculate the distance to an arbitrary point (common point). In addition, when the user is located in a large facility, the processor10refers to facility information in the map information123, calculates the floor number of the user and the distance to an exit of the facility using the altitude and position detected by the position detection device340of the user terminal apparatus300, and adds the calculated distance to the distance from the exit of the facility to an arbitrary point (common point) to calculate the distance for the user to reach the arbitrary point (common point). On the basis of the calculated distance, the processor10reads the walking speed of a general pedestrian, which is preliminarily stored, and calculates the time until the user arrives at the arbitrary point or the time at which the user arrives at the arbitrary point. The access cost regarding the arrival time of a user may be affected by the attribute of the user; therefore, as described in the third scheme, the walking speed may be set in accordance with the age and/or the load of a baggage. The processor10sequentially sets an arbitrary point on the route as a provisional common point, obtains the route for each user to the provisional common point, and calculates the time required for the user to reach the common point along the route. Schemes described in the above third scheme can be borrowed herein for the scheme of calculating the access cost.

The access cost regarding the load can be set in accordance with the position of a user and the attribute of the user. The access cost regarding the load may be added to the access cost regarding the distance or time or may also be used as a weighting coefficient for the access cost regarding the distance or time. When there is an altitude difference of a predetermined value or more along the route from the current location of the user to an arbitrary point (common point), the access cost regarding the load is calculated high. For example, when the user has to cross the overpass of a grade separation to move from the current location of the user to an arbitrary point (common point), the access cost is calculated high. This is because the up-and-down load on the overpass stairs is taken into account. When there is a slope along the route from the current location of the user to an arbitrary point (common point) and the user goes up the slope, the access cost is calculated higher than when going down the slope. This is because the load of going up the slope is taken into account. The slope of a route can be acquired from the road information122. When the user has to cross a pedestrian crosswalk along the route from the current location of the user to an arbitrary point (common point), the access cost is calculated high. This is because the load of moving to the opposite lane is taken into account. When the user is in a large facility, the access cost is calculated high. This is because the load of moving to an exit of the facility is taken into account.

When a user carries a large baggage in the attribute of the user obtained with the request, the access cost is calculated high. This is because the load of carrying the baggage is taken into account. When the age of a user is a predetermined value (old age) or more in the attribute of the user obtained with the request, the higher the age, the higher the access cost is calculated, while when the age is less than a predetermined value (child), the lower the age, the higher the access cost is calculated. When the distance or time accepted for movement is less than a predetermined value in the requirement from a user obtained with the request, the access cost is calculated higher than otherwise. This is because individual differences in the acceptance for movement are taken into account.

The calculation result of the access cost regarding the load may be used as a weighting coefficient for calculating the access cost regarding the distance/time. The coefficient can be set such that the access cost regarding the distance/time is a higher value as the value of the access cost regarding the load increases.

The processor10sequentially sets an arbitrary point on the route as a provisional common point, obtains respective routes for a plurality of users to the provisional common point, and calculates the time required for each user to reach the common point along the route for the user. A provisional common point having the smallest arrival time difference at the provisional common point is obtained as the common point to which the access costs for the users are equivalent. It is preferred to preliminarily register provisional common points in the map information123. The provisional common points to be preliminarily set may be set by selecting points to which the access difficulty level, which represents the difficulty for the vehicle to make a stop, is less than a predetermined value (access cost is low).

The access cost regarding the arrival time of a user who desires to alight and the access cost regarding the distance for the user are determined through referring to the map information123to calculate the distance from an arbitrary point (common point) to the request point (desired alighting point, destination), reading the walking speed of a general pedestrian, which is preliminarily stored, and calculating the time until the user arrives at the request point from the arbitrary point or the time at which the user arrives at the request point from the arbitrary point. The access cost regarding the arrival time of a user may be affected by the attribute of the user. The processor10may calculate the access cost by setting the walking speed to be lower as the age of the user is a predetermined value (old age) or more and the age is higher. The processor10may also calculate the access cost by setting the walking speed to be lower as the age of the user is less than a predetermined value (child) and the age is lower. When the user carries a large baggage such as a suitcase, the processor10may calculate the access cost by setting the walking speed to be lower than when the user does not carry such a baggage.

The processor10sequentially sets an arbitrary point on the route as a provisional common point, obtains respective routes for users from the provisional common point to the request point, and calculates the time required for each user to reach the request point along the route for the user. A provisional common point having the smallest arrival time difference at the request point from the provisional common point is obtained as the common point to which the access costs for the users are equivalent. Provisional common points may be preliminarily registered in the map information123. The provisional common points to be preliminarily set may be set by selecting points to which the access difficulty level, which represents the difficulty for the vehicle to make a stop, is less than a predetermined value (access cost is low).

The distance and time for a user to reach the request point from an arbitrary point (common point) on foot may be determined by taking into account not only the length of a road in the map information123but also a specific position of the request point, such as the floor of a facility or the position in the facility. In a large facility, the distance (required time) from an entrance to a destination (shop) is necessary for the user and may affect the distance (required time) to the request point. The processor10refers to a map of the facility in the map information123to calculate the distance (required time) from the entrance to the destination in the facility.

The access cost regarding the load can be set in accordance with the attribute of a user. The access cost regarding the load may be added to the access cost regarding the distance or time or may also be used as a weighting coefficient for the access cost regarding the distance or time. When there is an altitude difference of a predetermined value or more along the route from an arbitrary point (common point) to the request point, the access cost regarding the load is calculated high. For example, when the user has to cross the overpass of a grade separation to move from an arbitrary point (common point) to the request point, the access cost is calculated high. This is because the up-and-down load on the overpass stairs is taken into account. When there is a slope along the route from an arbitrary point (common point) to the request point and the user goes up the slope, the access cost is calculated higher than when going down the slope. This is because the load of going up the slope is taken into account. The slope of a route can be acquired from the road information122. When the user has to cross a pedestrian crosswalk along the route from an arbitrary point (common point) to the request point, the access cost is calculated high. This is because the load of moving to the opposite lane is taken into account. When the request point is in a large facility, the access cost is calculated high. This is because the load of moving from an entrance to a destination in the facility is taken into account.

When a user carries a large baggage in the attribute of the user obtained with the request, the access cost is calculated high. This is because the load of carrying the baggage is taken into account. When the age of a user is a predetermined value (old age) or more in the attribute of the user obtained with the request, the higher the age, the higher the access cost is calculated, while when the age is less than a predetermined value (child), the lower the age, the higher the access cost is calculated. When the distance or time accepted for movement is less than a predetermined value in the requirement from a user obtained with the request, the access cost is calculated higher than otherwise. This is because individual differences in the acceptance for movement are taken into account.

The calculation result of the access cost regarding the load may be used as a weighting coefficient for calculating the access cost regarding the distance/time. The coefficient can be set such that the access cost regarding the distance/time is a higher value as the value of the access cost regarding the load increases.

The processor10compares the access cost for a first user with the access cost for a second user different from the first user. The processor10calculates, as the common point, an arbitrary point for which a determination is made that the access costs regarding the time/distance/load to the common point are equivalent or the access costs regarding the time/distance/load from the common point to the destination are equivalent, that is, an arbitrary point for which a determination is made that the difference between the arrival time/distance/load for the first user to reach the common point and the arrival time/distance/load for the second user to reach the common point is less than a predetermined value or minimized. This common point is the predetermined point to which the target vehicle to be allocated moves. One or more users board/alight at the predetermined point. Here, the first user and the second user are described, but also for three or more users, the common point is calculated as an arbitrary point for which a determination is made that the difference between the arrival time/distance/load for a user to reach the common point and the arrival time/distance/load for another user to reach the common point is less than a predetermined value.

As illustrated inFIG. 5C, a common point PC1is calculated as the position at which a distance DD1(time TD1) for a user D1to reach a request point PB1from the common point PC1is substantially equal to a distance DU2(time TU2) for a user U2to reach the common point PC1from a current location PU2. Under the condition that the distance DD1(time TD1) and the distance DU2(time TU2) are substantially equal, the user D1moving from the common point PC1to the request point PB1and the user U2moving from the current location PU2to the common point PC1undertake similar access costs (walking distances, walking time, loads such as going up and down). This allows the vehicle to be allocated so that a plurality of users shares the same level of access cost, and the reliability of the system for the users can be enhanced. When there is a plurality of users who request boarding/alighting, the users gather at the common point at the same time and the vehicle can therefore adjust its speed and/or route thereby to obtain the appropriate timing for the users to board or alight. As a result, by shortening the staying time of the vehicle V1to be allocated, it is possible to suppress the disturbance of the traffic flow due to the allocated vehicle being parked.

The processor10calculates the access cost for a vehicle from an access difficulty level for the vehicle to reach the common point and calculates, as the common point, a point to which the access cost for the vehicle is lower than a predetermined value.

For each of arbitrary points, the processor10calculates the access difficulty level for a vehicle. The access difficulty level for a vehicle is determined, for example, using the access time or access distance to an arbitrary point (common point), the allowed staying time at an arbitrary point (common point), the presence or absence of a traffic signal (or the number of traffic signals) on the route to an arbitrary point (common point), and/or the necessity of a U-turn on the route to an arbitrary point (common point). The access cost is calculated as a higher value as the value of the access time or access distance for a vehicle to reach an arbitrary point (common point) increases. The access cost is calculated as a higher value as the allowed staying time at an arbitrary point (common point) decreases. The allowed staying time may be set in accordance with the traffic volume. As the traffic volume at an arbitrary point (common point) increases, the allowed staying time decreases, and the access cost is therefore calculated as a higher value. When there is a traffic signal on the route to an arbitrary point (common point), the access cost is calculated as a higher value than when there is no traffic signal. The access cost is calculated as a higher value as the number of traffic signals on the route to an arbitrary point (common point) increases. When a U-turn is required on the route to an arbitrary point (common point), the access cost is calculated to a higher value than when no U-turn is required.

The processor10compares the access cost to each arbitrary point (common point) with a set threshold. The processor10calculates, as the common point, an arbitrary point to which the access cost is a lower value than a predetermined value. This common point is the predetermined point to which the allocated vehicle moves.

As illustrated inFIG. 5D, the processor10calculates a point to which an access cost AV1is a lower value than a predetermined value as a common point PC1. The route search process may include preliminarily calculating the access cost AV1to each arbitrary point (common point) and storing the calculated access cost AV1as a part of the map information123. This allows the point with a low access cost for the vehicle to be selected as the common point, and it is possible to ensure that the vehicle is controlled to make a stop at the common point and the user is allowed to board or alight at the common point.

Referring again toFIG. 3, in step106, the processor10presents the calculated common point to each user using the user terminal apparatus300. A single common point may be presented or a plurality of common points may also be presented. In step107, the processor10makes an inquiry to the user about the user's acceptance of the common point via the user terminal apparatus300. The processor10controls the user terminal apparatus300to output a message for confirming the user's intention, such as «Do you accept boarding at the common point?», «Do you accept alighting at the common point?», or «Do you fix the reservation?». The user terminal apparatus300receives the input of an acceptance instruction for the common point. The acceptance instruction includes an input command for selecting one common point from among a plurality of common points. In this case, the processor10controls the user terminal apparatus300to output a message for confirming the user's selection intention and usage intention, such as «There is a plurality of boarding point candidates. Please specify the boarding point» or «There is a plurality of alighting point candidates. Please specify the alighting point».

In step107, the processor10confirms the user's acceptance. When the user's acceptance is not obtained, the process proceeds to step112, in which the request for boarding or alighting is canceled. When the user's acceptance is obtained, the process proceeds to step108, in which one accepted common point is set as the predetermined point. The predetermined point is a point to which the allocated vehicle is controlled to move and at which the user is allowed to board or alight. Thus, each predetermined point to which the vehicle is controlled to move is calculated after confirming the user's acceptance, and the user can therefore board or alight at a point that matches the user's intention.

In step109, the processor10controls the navigation device120to calculate a route for sequentially following the predetermined points. The processor10creates a vehicle allocation plan in accordance with the calculated route. The processor10selects a vehicle closest to the start point of the route (predetermined point to be followed first) as the target vehicle to be allocated.

In step110, the processor10transmits, to the vehicle controller70of the target vehicle, the created vehicle allocation plan and an instruction for the target vehicle to autonomously move along the vehicle allocation plan. The vehicle allocation plan includes the predetermined points at which the vehicle picks up/drops off the users and the route for following the predetermined points. The vehicle controller70executes the above-described autonomous travel control on the basis of the vehicle allocation plan and controls the vehicle to move along the route.

On the basis of the vehicle allocation plan, the vehicle controller70controls the vehicle to make stops at the predetermined points (including the common point and one or more request points) located along the route and opens the door for boarding/alighting. After the door is opened, the door is closed when a predetermined time has elapsed. The processor10controls the vehicle controller to confirm that the vehicle has stopped. Execution of boarding or alighting is confirmed on the basis of the detection results from a door lock sensor (not illustrated), a seating sensor (not illustrated), and a seat belt sensor (not illustrated) included in the sensor60and images captured by a vehicle interior camera (not illustrated) included in the detection device50. After the users' boarding or alighting included in the vehicle allocation plan is completed, the vehicle is controlled to move to the next predetermined point. The processor10creates a vehicle allocation plan for another target vehicle and transmits an instruction for the target vehicle to autonomously move along the vehicle allocation plan to the vehicle controller70of the target vehicle.

In this example, the boarding/alighting point determination apparatus100operates to control the creation/execution of the vehicle allocation plan. The creation/execution of the vehicle allocation plan may be executed by a processor (not illustrated) provided separately in the vehicle allocation system1.

The boarding/alighting point determination apparatus100according to one or more embodiments of the present invention is configured and operates as the above and therefore has the following effects.

(1) The boarding/alighting point determination method according to one or more embodiments of the present invention includes specifying a second user who is expected to board/alight in a predetermined range including a point associated with a first user and calculating, as the predetermined point, a common point at which users including at least the first user and the second user board/alight, and it is therefore possible to prevent a vehicle from making frequent stops and suppress an increase in the trip time while responding to the request from each user who desires the use of the vehicle allocation system. By reducing the number of stops, it is possible to suppress the energy consumption, improve the fuel efficiency of the vehicle, and reduce the time required for passing from the first predetermined point to the last predetermined point in the vehicle allocation service.

According to the boarding/alighting point determination method in one or more embodiments of the present invention, users are specified on the basis of one or more request points and it is therefore possible to calculate the predetermined points including the boarding points or alighting points along the desires of users. The users who share a ride on a vehicle can be preliminarily specified; therefore, unnecessary information is not given to unrelated users and the system load can be reduced.

According to the boarding/alighting point determination method in one or more embodiments of the present invention, by calculating the common point on the basis of the request point, it is possible to calculate the common point along the desire of a user. The common point is calculated on the basis of the request point of a user, and a reasonable common point can therefore be calculated with consideration for the distance from the user. When there is a plurality of specified users, a common point reasonable for the plurality of users can be calculated on the basis of the request points of the plurality of users. When there is one specified user, a common point reasonable for the user and a vehicle to be allocated can be calculated on the basis of the request point of the user.

(2) According to the boarding/alighting point determination method in one or more embodiments of the present invention, by calculating the common point on the basis of the request point of a user, it is possible to calculate the common point along the desire of the user. Among the request points of a plurality of users, one request point of a user or request points of a plurality of users may be set as the common point, and the number of users moving to the common point can therefore be minimized. A request point may be set as the common point. The process of calculating the common point is not required, and the system load can therefore be reduced. When there is one specified user, a common point reasonable for the user and a vehicle to be allocated can be obtained without a calculation load because the request point of the user is set as the common point.

(3) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the request point is set as the boarding point desired by a user, the current location of a user, the alighting point desired by a user, or the destination of a user, and the common point can thereby be calculated as a point that is convenient for a user who desires boarding or alighting. When the request point for boarding is set as the current location, the current location is automatically collected, and the user's input work can therefore be omitted. By receiving the input of a boarding point desired by a user, it is possible to request the vehicle allocation even at a location at which the current location cannot be detected or a location at which the detection accuracy for the current location is poor.

(4) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the cost calculated from the time for a user to reach the common point or the cost calculated from the time for a user to reach the destination from the common point is calculated as the access cost for the user, the cost calculated from the time for a vehicle to reach the common point is calculated as the access cost for the vehicle, and a point for which a determination is made that the access cost for the vehicle and the access cost for the user are equivalent is calculated as the common point.

This can prevent the vehicle V1from staying for a long time to wait for the user U1. By shortening the staying time of the vehicle V1to be allocated, it is possible to suppress the disturbance of the traffic flow due to the allocated vehicle being parked. The waiting time for each of the user and the vehicle can be minimized because the common point is set as a point at which the difference between the arrival time of the user and the arrival time of the vehicle is small (or a point at which the user and the vehicle arrive at the same time).

(5) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the cost calculated from any one of the time for a user to reach the common point, the distance for the user to reach the common point, and the load for the user to reach the common point, or the cost calculated from any one of the time for a user to reach the destination from the common point, the distance for the user to reach the destination from the common point, and the load for the user to reach the destination from the common point, is calculated as the access cost for the user, and a point for which a determination is made that the access cost for a first user and the access cost for a second user are equivalent is calculated as the common point.

This allows the vehicle to be allocated so that a plurality of users who request boarding or alighting shares the same level of access cost, and the reliability of the system for the users can thus be enhanced. The users gather at the common point at the same time and the vehicle can therefore adjust its speed and/or route thereby to obtain the appropriate timing for the users to board/alight. As a result, by shortening the staying time of the vehicle V1to be allocated, it is possible to suppress the disturbance of the traffic flow due to the allocated vehicle being parked. The waiting time for each of the users can be minimized because the common point is set as a point at which the difference between the arrival time of a user and the arrival time of another user is small (or a point at which a user and another user arrive at the same time).

(6) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the access cost for a vehicle is calculated from the access difficulty level for the vehicle to reach the common point, and a point to which the access cost for the vehicle is a lower value than a predetermined value is calculated as the common point. It is therefore possible to ensure that the vehicle is controlled to make a stop at the common point and a user is allowed to board or alight at the common point.

(7) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the predetermined range is set as an area that is preliminarily set, and the load of the calculation process for specifying a user can therefore be reduced.

(8) According to the boarding/alighting point determination method in one or more embodiments of the present invention, by determining the predetermined range so as to include the request points, users can be narrowed down to those located in the vicinity of respective request points (current locations, desired boarding locations, destinations, desired alighting locations), and the predetermined points can therefore be set to include the boarding points or alighting points along the desires of users. The predetermined range is determined in accordance with the users' request points which change from moment to moment, and the predetermined range can therefore be set in accordance with the current situation to specify the users.

(9) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the predetermined range is set on the basis of attributes of users who made requests, and the predetermined points can be set, including the boarding points or alighting points determined to give importance to the convenience of the users.

(10) According to the boarding/alighting point determination method in one or more embodiments of the present invention, an inquiry is made to a user about an acceptance of the common point, and the common point is set as the predetermined position when the acceptance is obtained from the user; therefore, the user is allowed to board/alight at the point which matches the user's intention.

(11) According to the boarding/alighting point determination method in one or more embodiments of the present invention, one vehicle is used by a plurality of users and it is therefore possible to prevent the vehicle from making frequent stops and suppress an increase in the trip time. By reducing the number of stops, it is possible to suppress the energy consumption, improve the fuel efficiency of the vehicle, and reduce the time required for passing from the first predetermined point to the last predetermined point in the vehicle allocation service. Moreover, the usage efficiency of the vehicle can be improved.

(12) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the processor operates to calculate the common point that is a point at which a plurality of users of specified users boars/alight. The common point is a predetermined point at which the vehicle and one or more users get together. The plurality of users is allowed to board/alight at one common point; therefore, the number of stops can be reduced, and one trip time (the time required for passing from the first predetermined point to the last predetermined point in the vehicle allocation service) can be shortened. By reducing the number of stops, it can be expected to suppress the energy consumption and improve the fuel efficiency of the vehicle.

(13) According to the boarding/alighting point determination method in one or more embodiments of the present invention, the vehicle has an autonomous travel function. By calculating the common point, it is possible to reduce the number of points at which the autonomously traveling vehicle makes stops to allow the users to board/alight, thus reducing the trip time. The autonomous traveling is performed on the basis of the vehicle allocation plan in which the predetermined points are defined to allow the users to board/alight, and human errors do not occur, such as the vehicle passing through the predetermined point without noticing the stop point.

(14) The boarding/alighting point determination apparatus100according to one or more embodiments of the present invention has similar actions and effects to those obtained by the above-described boarding/alighting point determination method.

Embodiments heretofore explained are described to facilitate understanding of the present invention and are not described to limit the present invention. It is therefore intended that the elements disclosed in the above embodiments include all design changes and equivalents to fall within the technical scope of the present invention.
