Description

Vehicle allocation management device and vehicle allocation management method

[0001] The present invention relates to a vehicle allocation management technology, and more particularly to a vehicle allocation management device and a vehicle allocation management method for managing vehicle allocation on an on-demand basis.

[0002] Mobility services are services that provide smooth transportation of users and transport of luggage by vehicle. Examples of mobility services include car sharing services that allow multiple users to share vacant vehicles parked in nearby parking lots for a set time period, and ride sharing services that allow multiple passengers to ride together. Mobility services require efficient vehicle allocation planning to increase vehicle utilization rates and improve user (passenger) convenience.

[0003] For example, Patent Document 1 below discloses a vehicle dispatch service system that dispatches a vehicle according to a user's condition information (urinary urge state, type of illness, injury state, priority, etc.).

[0004] Japanese Patent Application Laid-Open No. 2020-119038

[0005] In mobility services, vehicles assigned in response to a user's request for a ride drive along a route from the user's desired boarding location to the user's desired drop-off location. Such routes have various characteristics (route characteristics) due to road conditions, traffic conditions, etc., and some vehicles may not be compatible with such route characteristics depending on their characteristics (performance). The technology disclosed in Patent Document 1 did not take into consideration vehicle performance according to the route characteristics when assigning vehicles, which could result in the allocation of vehicles that are not adequately suited to traveling to the destination. In particular, in the case of autonomously driven vehicles, unless sufficient vehicle performance according to the route characteristics is considered, the vehicle cannot be properly driven to the destination. For example, in a route that includes route characteristics such as heavy pedestrian traffic, it is desirable to assign vehicles that are adequately equipped with functions (such as detection, recognition, and movement functions) to deal with obstacles around the vehicle.

[0006] Therefore, an object of the present invention is to provide a vehicle dispatch management device and a vehicle dispatch management method that can improve the level of service (LoS) by appropriately allocating a vehicle having vehicle performance that is suited to the characteristics of the driving route in response to a user's vehicle dispatch request.

[0007] The present invention, which aims to solve the above problems, comprises the following invention-specifying matters and technical features.

[0008] According to one aspect, the present invention provides a vehicle dispatch management device that manages vehicle dispatches in response to vehicle dispatch requests. The vehicle dispatch management device includes: a vehicle dispatch request acquisition unit that acquires a vehicle dispatch request indicating at least a desired boarding location; a vehicle information database that stores vehicle information associated with each of a plurality of vehicles, including information on vehicle performance; a vehicle dispatch plan creation unit that creates a vehicle dispatch plan including at least a travel route for each of two or more candidate vehicles selected from the plurality of vehicles based on the acquired vehicle dispatch requests, and confirms a vehicle dispatch plan for a specific vehicle selected from the created vehicle dispatch plans; and a vehicle dispatch instruction unit that transmits the confirmed vehicle dispatch plan to the specific vehicle. The vehicle dispatch plan creation unit includes a route characteristic determination unit that determines route characteristics for the travel route; a vehicle performance identification unit that identifies the vehicle performance of the candidate vehicle based on the vehicle information stored in the vehicle information database; and a vehicle selection unit that selects the specific vehicle having the vehicle performance that matches the determined route characteristics.

[0009] According to another aspect, the present invention provides a vehicle dispatch management method using a vehicle dispatch management device that manages vehicle dispatches in response to a vehicle dispatch request. The method includes: storing vehicle information associated with each of a plurality of vehicles, including information about vehicle performance, in a vehicle information database; receiving a vehicle dispatch request from a user's terminal device, the vehicle dispatch request indicating at least a desired boarding location; creating a vehicle dispatch plan including at least a travel route for each of two or more candidate vehicles selected from the plurality of vehicles based on the received vehicle dispatch request; confirming the vehicle dispatch plan for a specific vehicle selected from the created vehicle dispatch plan; and transmitting the confirmed vehicle dispatch plan to the specific vehicle. Creating the vehicle dispatch plan includes determining route characteristics for the travel route indicated by the vehicle dispatch plan; identifying the vehicle performance of the candidate vehicle based on the vehicle information stored in the vehicle information database; and selecting the candidate vehicle having the vehicle performance that matches the determined route characteristics as the specific vehicle.

[0010] According to the present invention, a vehicle having vehicle performance suited to the route characteristics is appropriately allocated in response to a user's vehicle dispatch request, thereby making it possible to improve the level of service (LoS).

[0011] Other technical features, objects, and operational effects or advantages of the present invention will become apparent from the following embodiments described with reference to the accompanying drawings.

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are merely examples, and are not intended to exclude various modifications or applications of techniques not explicitly described below. The present invention can be implemented in various modifications (e.g., by combining the various embodiments) without departing from the spirit of the present invention. Furthermore, in the following description of the drawings, identical or similar parts are denoted by identical or similar reference numerals. The drawings are schematic and do not necessarily correspond to actual dimensions, ratios, etc. Parts in the drawings may have different dimensional relationships or ratios.

[0014] 1 is a diagram illustrating an example of a vehicle dispatch management system according to an embodiment of the present invention. As shown in the figure, the vehicle dispatch management system 1 includes a vehicle dispatch management device 10, a terminal device 20, and a vehicle V, which are interconnected via a communication network N so as to be able to communicate with each other. The vehicle dispatch management system 1 can also be connected via the communication network N to a road traffic information management system 30 that provides various traffic information in real time.

[0015] The vehicle dispatch management system 1 of the present disclosure provides, for example, an on-demand vehicle dispatch service using multiple vehicles V for a certain area. The "on-demand vehicle dispatch service" is a service that allocates (dispatches) a specific vehicle to a user in immediate response to a vehicle dispatch request from the user. In other words, in an on-demand vehicle dispatch service, there is no user-specified vehicle dispatch reservation time. Furthermore, "immediate response" is a concept that not only means dispatching a vehicle immediately in response to a user's vehicle dispatch request, but also includes a certain degree of time that the user would normally tolerate. In the present disclosure, the vehicle dispatch management system 1 is premised on such an "on-demand vehicle dispatch service," but is not limited thereto and may also be applied to, for example, a reservation-based vehicle dispatch service. Furthermore, the vehicle V includes so-called manned vehicles driven by a driver and unmanned vehicles capable of autonomous driving.

[0016] The vehicle dispatch management device 10 is a computing device that comprehensively manages a vehicle dispatch service using multiple vehicles V in a target area. The vehicle dispatch management device 10 implements, for example, a vehicle dispatch management server program and executes the vehicle dispatch management server program under the control of a processor, thereby realizing the vehicle dispatch service of the present disclosure.

[0017] The vehicle dispatch management device 10 includes various databases 12 that accumulate and manage data necessary to realize the vehicle dispatch service. As will be described later, the databases 12 include, for example, a user information database 12a, a road map information database 12b, a vehicle information database 12c, a vehicle dispatch plan database 12d, and an operation history information database 12e (see FIG. 2). In this example, the databases 12 are configured as part of the vehicle dispatch management device 10, but this is not limiting, and all or part of the databases 12 may be configured separately from the vehicle dispatch management device 10.

[0018] In general, the vehicle dispatch management device 10 receives a dispatch request from a user who desires to dispatch a vehicle V for travel, creates a dispatch plan for candidate vehicles V (candidate vehicles v) extracted from a plurality of vehicles V based on the dispatch request, determines a dispatch plan for the optimal vehicle V from the created dispatch plans, and issues dispatch instructions to the vehicle V in accordance with the determined dispatch plan. The dispatch plan is determined, for example, in response to the user's consent.

[0019] The following description will be given using an example of a vehicle dispatch request for a ride from a user who is a passenger, but the vehicle dispatch request may also be a vehicle dispatch request for luggage delivery from a user who is a shipper (a luggage delivery company or a general person). Therefore, a general user who is not a luggage delivery company may also request a luggage delivery vehicle to have their luggage delivered. The vehicle dispatch request includes information such as the user name, boarding and disembarking locations (desired boarding and disembarking locations), transportation details (number of people, etc.), etc.

[0020] The vehicle dispatch plan includes a travel route that defines a route from a location where the vehicle V is waiting (a starting location), passing through several points (boarding and disembarking locations) along the way where the user gets on and off, to a destination location (which may not necessarily be the same as the initial location). If the vehicle V is waiting, the vehicle dispatch plan may be newly created based on a new dispatch request. If the vehicle V is in operation, the vehicle dispatch plan may be updated based on a new dispatch request. In the present disclosure, the vehicle dispatch management device 10 determines route characteristics for the travel route in a vehicle dispatch plan created for a candidate vehicle V extracted from multiple vehicles V based on a user's dispatch request, selects a candidate vehicle V having vehicle performance that matches the route characteristics, and proposes the vehicle dispatch plan to the user. The route characteristics are determined based on risk factors such as road width, height restrictions, and the like, as well as the likelihood of people running out into the road, crowds, difficulty of driving at intersections, and the number of parked and stopped vehicles. This allows a vehicle V that matches the travel route based on the user's dispatch request to be assigned, ensuring reliable travel of the vehicle V.

[0021] The vehicle V is a vehicle registered in the vehicle information database 12c and available for use by a user. The vehicle V may be of any type (e.g., sedan, minivan, SUV, etc.). The vehicle V may be an electric vehicle (EV) powered by an on-board battery. The vehicle V may also be a fully autonomous vehicle (unmanned vehicle), regardless of the level of so-called automation. The vehicle V is equipped with a control device 500 that controls the vehicle V itself or its onboard equipment (e.g., a navigation device) in accordance with instructions from the vehicle dispatch management device 10 (see FIG. 2). The control device 500 acquires geographical location information (hereinafter referred to as "location information") of the vehicle V via, for example, a GPS system, transmits this information to the vehicle dispatch management device 10, and controls the operation of various devices or equipment of the vehicle V upon receiving dispatch instructions from the vehicle dispatch management device 10. The control device 500 includes, for example, a navigation function that presents the driver with a driving route according to a vehicle dispatch plan, and in the case of an unmanned vehicle V_NAD, an autonomous driving control function that determines a detailed actual driving route based on the driving route of the vehicle V and follows the actual driving route.

[0022] The terminal device 20 is, for example, a computing device through which a user wishing to ride makes a vehicle dispatch request by operating a user interface. The terminal device 20 is, for example, a smartphone, a pad computer, a laptop personal computer, a desktop computer, etc., but is not limited to these. The terminal device 20 implements, for example, a vehicle dispatch management client program (a so-called vehicle dispatch app). The terminal device 20 executes the vehicle dispatch app under the control of a processor, thereby enabling the user to use the vehicle dispatch service of the vehicle dispatch management device 10. For example, the user can make a vehicle dispatch request from a vehicle dispatch request screen (not shown) on the user interface of the terminal device 20 and, in response, accept the vehicle dispatch plan created by the vehicle dispatch management device 10, thereby reserving a ride in the vehicle V.

[0023] The road traffic information management system 30 is an information and communication system that provides road traffic information in real time. For example, the road traffic information management system 30 collects road traffic data from vehicle sensors and cameras installed on roads, and also collects driving data from a control device 500 mounted on the vehicle V, and manages road traffic information that is processed and edited in an integrated manner. The edited road traffic information may include, for example, information on road closures and detour routes, and the required time between points via a specific route. The road traffic information management system 30 provides the road traffic information to the vehicle dispatch management device 10 and the vehicle V as appropriate.

[0024] In this way, in the vehicle dispatch management system 1 disclosed herein, in an on-demand vehicle dispatch service, in response to a user's vehicle dispatch request, a vehicle dispatch plan is created for each candidate vehicle v extracted from multiple vehicles V, the route characteristics of the operating route in the vehicle dispatch plan are evaluated or determined, and a vehicle V having vehicle performance that matches the route characteristics is assigned to the user, thereby enabling the vehicle V to be operated safely and reliably.

[0025] FIG. 2 is a block diagram illustrating an example of a functional configuration model of a vehicle dispatch management device according to an embodiment of the present invention. As shown in the figure, the vehicle dispatch management device 10 is configured as a functional configuration model including functional components such as a front-end processing unit 110, a vehicle dispatch request acquisition unit 120, a boarding / alighting location determination unit 130, a vehicle dispatch plan creation unit 140, a driving route planning unit 150, and a vehicle communication interface unit 160. As described above, the vehicle dispatch management device 10 also includes various databases 12. This functional model is realized by the vehicle dispatch management device 10 executing a vehicle dispatch management server program under the control of a processor, thereby cooperating with various hardware resources. The functional configuration model shown here is merely an example, and all or part of the functions of a certain functional component may be realized by other functional components. For ease of explanation, the figure also illustrates a user's terminal device 20 and a control device 500 in the vehicle V.

[0026] The user information database 12a stores information about users who use the vehicle dispatch service (hereinafter referred to as "user information"). The user information includes, for example, a user ID and password, personal attributes, and information about service usage. The user information is registered in the user information database 12a under the control of the vehicle dispatch management device 10 by the user inputting predetermined information, for example, when the vehicle dispatch app is first launched.

[0027] The road map information database 12b stores information about road maps (hereinafter referred to as "road map information") in the target area of ​​the ride-hailing service. FIG. 3 is a diagram conceptually illustrating the road map information stored in the road map information database 12b. In the figure, the symbol P_PU indicates a desired pickup location. As shown in the figure, the road map information includes map data related to addresses, place names, roads, facilities, etc. The road map information may also include information necessary for route search, such as road information, feature information, and environmental information. This information may include risk factors in the operation of the vehicle V. The road information includes, for example, information about traffic regulations such as speed limits, one-way streets, no right or left turns, no parking or stopping, and road closures, road types such as community roads and main roads, and traffic light control at intersections. The feature information includes, for example, the conditions between buildings and roads (e.g., sidewalk width, the presence or absence of obstructions such as guardrails and shrubbery, the degree of visibility, etc.). The environmental information includes, for example, the status of parked and stopped vehicles and pedestrians at each location by time of day, the frequency of vehicles turning right or left at intersections, the frequency of parking and stopping, and the frequency of traffic accidents.

[0028] Returning to FIG. 2 , the vehicle information database 12c stores information (vehicle information) about the vehicle V available for use by the user. The vehicle information includes, for example, a vehicle ID, vehicle attributes (vehicle registration number, vehicle model, maximum occupancy / maximum load capacity, whether driven or unmanned, etc.), vehicle performance, other specifications, a current vehicle dispatch plan, a current location, and a current status (service status, remaining battery capacity (travel distance), number of occupants, etc.). The information about vehicle performance (vehicle performance information) includes, for example, performance data about a sensing function, an object identification function, an automatic emergency braking function, an automatic collision avoidance function, a vehicle-to-vehicle tracking function, etc. The current location of the vehicle V can be updated as needed based on location information transmitted from the vehicle V.

[0029] The vehicle allocation plan database 12d stores a vehicle allocation plan for each vehicle V created by the vehicle allocation plan creation unit 140 based on a vehicle allocation request. The vehicle allocation plan includes a travel route from a waiting location serving as a starting point to a waiting location serving as a terminal point via several boarding and disembarking points, an estimated arrival time at each stopover point, and the like.

[0030] The operation history information database 12e stores, for example, information (operation history information) relating to the past operation history of each vehicle V. The operation history information includes, for example, various specification information for each vehicle V, such as the operation time (operation start time and operation end time), operation route, and mileage.

[0031] Although not shown, the database 12 may include a driver information database that stores information (driver information) about the driver who drives the manned-operated vehicle V_NAD. The driver information includes, for example, information about the driver ID and password, personal attributes, driving history, work performance, etc.

[0032] The front-end processing unit 110 performs various processes with the user's terminal device 20. As an example, the front-end processing unit 110 refers to the user information database 12a and performs login authentication processing in response to a login request from a vehicle dispatching app on the user's terminal device 20. The front-end processing unit 110 also accepts a vehicle dispatch request from the vehicle dispatching app on the user's terminal device 20, passes the request to the vehicle dispatch request acquisition unit 120, and interacts with the terminal device 20 to receive the user's approval or rejection of the vehicle dispatch plan created by the vehicle dispatch plan creation unit 140 in response to the request. That is, the front-end processing unit 110 transmits an approval request including the created vehicle dispatch plan to the terminal device 20, displays the vehicle dispatch plan on the user interface of the terminal device 20, and receives a notification of approval or rejection sent from the terminal device 20 in response to the request. In this sense, the front-end processing unit 110 also functions as an approval processing unit under the control of the vehicle dispatch plan creation unit 140.

[0033] The vehicle allocation request acquisition unit 120 receives and acquires a vehicle allocation request from a user via the front-end processing unit 110. The time when the vehicle allocation request acquisition unit 120 receives the vehicle allocation request becomes the start time for timing various limit times (e.g., boarding limit time and disembarking limit time). The vehicle allocation request acquisition unit 120 passes the acquired vehicle allocation request to each of the boarding and alighting location determination unit 130 and the vehicle allocation plan creation unit 140.

[0034] Based on the dispatch request that has been delivered, the boarding and alighting location determination unit 130 refers to the road map information database 12b and determines predetermined boarding and alighting locations (e.g., bus stops) that are shown on the road map and where the user can actually get on and off. That is, the boarding and alighting location determination unit 130 refers to the road map information database 12b for the desired boarding location and desired alighting location indicated in the dispatch request, and determines boarding locations and alighting locations that indicate geographical locations in the target area where the user can actually get on and off. The boarding and alighting location determination unit 130 delivers the determined boarding and alighting locations to the dispatch plan creation unit 140.

[0035] The vehicle allocation plan creation unit 140 extracts candidate vehicles (candidate vehicles v) from the vehicles V in the target area based on the given vehicle allocation request, creates a vehicle allocation plan for the candidate vehicles, selects and confirms the vehicle V with the optimal vehicle allocation plan from the created vehicle allocation plans, and issues a vehicle allocation instruction to the vehicle V according to the confirmed vehicle allocation plan. In order to extract the candidate vehicles v, the vehicle allocation plan creation unit 140 requests the travel route planning unit 150 to derive a route pattern. The vehicle allocation plan creation unit 140 proposes the created vehicle allocation plan to the user and confirms it upon receiving the user's consent. The vehicle allocation plan creation unit 140 may present multiple candidate vehicle allocation plans to the user, allow the user to select a specific vehicle allocation plan from among them, and confirm the selected plan. The vehicle allocation plan creation unit 140 stores the confirmed vehicle allocation plan in the vehicle allocation plan database 12d and notifies the vehicle allocation instruction unit 162 to issue a vehicle allocation instruction to the corresponding vehicle V.

[0036] In the present disclosure, the vehicle allocation plan creation unit 140 is configured to determine route characteristics of a service route in a vehicle allocation plan created based on a user's vehicle allocation request, and to select a vehicle V (specific vehicle V) having vehicle performance that matches the determined route characteristics from among candidate vehicles v. The vehicle allocation plan creation unit 140 is configured to include, for example, a route characteristics determination unit 141, a vehicle performance identification unit 142, and a vehicle selection unit 143. Details of these functional components of the vehicle allocation plan creation unit 140 will be described later.

[0037] The travel route planning unit 150 derives a route pattern for each candidate vehicle v under the control of the vehicle allocation plan creation unit 140. The route pattern indicates a route that passes through all of the previously determined boarding and alighting points (waypoints) when a boarding and alighting point is added in response to a new vehicle allocation request. For example, the route pattern may be expressed as a lattice structure in which roads are links and their branching points (intersections) are nodes. In response to a request for derivation of a route pattern from the vehicle allocation plan creation unit 140, the travel route planning unit 150 refers to the road map information database 12b and the vehicle information database 12c to extract one or more vehicles V that can meet the vehicle allocation request as candidate vehicles v, and derives a route pattern for each of the extracted candidate vehicles v according to the boarding and alighting points. In addition, the travel route planning unit 150 associates road map information, including road information, feature information, environmental information, etc., with the derived route pattern (e.g., links and / or nodes). The driving route planning unit 150 passes the derived route pattern to the vehicle allocation plan creating unit 140 .

[0038] The vehicle communication interface unit 160 exchanges various types of information with the vehicle V via the communication network N. For example, the vehicle communication interface unit 160 includes a vehicle information acquisition unit 161 that acquires vehicle information including location information of the vehicle V, and a vehicle allocation instruction unit 162 that instructs the vehicle V to move according to a vehicle allocation plan.

[0039] The vehicle information acquisition unit 161 communicates with the communication unit 510 of the control device 500 and acquires vehicle information including location information acquired by the location information acquisition unit 520 (see FIG. 5 ). Furthermore, the vehicle allocation instruction unit 162, in accordance with instructions from the vehicle allocation plan creation unit 140, refers to the vehicle allocation plan database 12d, identifies a corresponding vehicle allocation plan, and transmits driving instructions to the vehicle V according to the identified vehicle allocation plan. Having received the driving instructions, the control device 500 of the vehicle V uses a navigation function to display a driving route according to the vehicle allocation plan on, for example, a user interface (indicated as "UI" in the drawing) 530. Alternatively, the control device 500 determines a detailed actual driving route according to the driving route in the vehicle allocation plan, and performs control so that the vehicle V drives autonomously along the actual driving route.

[0040] Next, the functional components of the vehicle allocation plan creation unit 140 will be described in detail.

[0041] The route characteristic determination unit 141 determines the route characteristics of the travel route in the vehicle dispatch plan for the candidate vehicle v. That is, the route characteristic determination unit 141 identifies risk factors for each link / node in the travel route based on road map information associated with the links / nodes in the route pattern and road traffic information acquired from the road traffic information management system 30, and determines the route characteristics of the travel route. By using real-time road traffic information in addition to road map information, the route characteristic determination unit 141 can determine route characteristics that are more in line with the current situation. Route characteristics may be assigned a score, for example, from 0 to 9 (e.g., the higher the score, the higher the required vehicle performance). For example, a route that includes narrow residential roads and intersections with poor visibility will receive a higher route characteristic score. In addition, the route characteristic score may be calculated based on visibility by time period (e.g., evening, night, etc.) and the number of pedestrians and vehicles passing by. Furthermore, a score may be added if a traffic accident has occurred at that location in the past. For example, the route characteristic determination unit 141 may calculate a risk factor score for each link / node in the travel route and determine the highest link / node score as the route characteristic score. Therefore, it becomes possible to select the candidate vehicle v according to the vehicle performance that is suited to the route characteristic based on the highest risk factor.

[0042] Furthermore, the route characteristic determination unit 141 may determine route characteristics based on the risk factors of each link / node indicated by the operation history information stored in the operation history information database 12e. For example, if the operation history information includes sudden braking (hard braking) or abrupt steering operations in past travels along the operation route by the vehicle V, the score of the route characteristics may be high. This allows past risk factors obtained from the operation history of the vehicle V to be reflected in the route characteristics.

[0043] The route characteristics determination unit 141 may also acquire weather information from a weather forecast service site (not shown) and use the acquired weather information to calculate the route characteristics of the travel route. For example, if it is raining, visibility will be reduced, and the score will increase.

[0044] The vehicle performance identification unit 142 refers to the vehicle information database 12c and identifies vehicle performance based on vehicle information including the vehicle performance information of the candidate vehicle V. The vehicle performance information includes, but is not limited to, performance data related to a sensing function, an object identification function, an automatic emergency braking function, an automatic collision avoidance function, a vehicle-to-vehicle tracking function, and the like. The vehicle performance identification unit 142 may score the vehicle performance according to the vehicle performance information of the vehicle V. For example, the more functions listed here are provided and / or the more advanced the functions are, the higher the score of the vehicle performance will be.

[0045] The vehicle selection unit 143 selects a vehicle V having vehicle performance that matches the route characteristics from among the extracted candidate vehicles v, based on the route characteristics determined by the route characteristics determination unit 141 and the vehicle performance identified by the vehicle performance identification unit 142. When multiple candidate vehicles v having vehicle performance that matches the route characteristics are extracted, the vehicle selection unit 143 preferentially selects the candidate vehicle v with the lowest vehicle performance score. In other words, as long as the vehicle performance of the vehicle V matches the route characteristics, there is no problem with the vehicle dispatch service, and by selecting vehicles V in descending order of vehicle performance, it becomes possible to prepare vehicles V for future situations in which higher vehicle performance will be required.

[0046] The vehicle selection unit 143 may include a vehicle performance requirement table showing the relationship between risk factors and vehicle performance, such as that shown in FIG. 4 . Risk factors include, but are not limited to, pedestrian density (crowding), people jumping out, parked vehicles, fallen objects, traffic jams, obstructions, poor visibility, time of day, road width, and number of lanes. Functional requirements include, but are not limited to, an object identification function, an automatic emergency braking function, an automatic collision avoidance function, and a distance tracking function. The object identification function is a function that identifies people and objects (vehicles, roads, features, etc.) based on images captured by an optical camera or the like. The automatic emergency braking function is a function that automatically applies emergency braking in response to a vehicle jumping out, etc. The automatic collision avoidance function is a function that automatically operates the steering wheel to change course in response to a vehicle jumping out, etc. The distance tracking function is a function that maintains a constant distance between the vehicle and the vehicle ahead while driving. For example, for a link / node (road) associated with the risk factor of "running out into the street," a vehicle V equipped with a sensing function, an object identification function, an automatic emergency braking function, and an automatic collision avoidance function is required. The vehicle selection unit 143 refers to the vehicle performance requirement table, identifies the vehicle performance required for the route characteristics of the travel route, and selects a vehicle V having such vehicle performance from among the candidate vehicles v.

[0047] Furthermore, the vehicle selection unit 143 may select the vehicle V based on the risk factor of the link / node with the highest risk factor score among the links / nodes on the travel route. In other words, since the route characteristics determination unit 141 determines the route characteristics based on the link / node with the highest risk factor score, the vehicle selection unit 143 can select the vehicle V in accordance with the route characteristics. For example, the risk factor score of a link / node with heavy traffic and heavy pedestrian traffic will be relatively high. Therefore, the vehicle selection unit 143 can select the vehicle V based on the highest score of such a risk factor. This allows the vehicle V that is more suited to the route characteristics to be selected, ensuring that the vehicle V will travel safely and appropriately to the destination.

[0048] 5A and 5B are block diagrams showing functional models of control devices mounted on vehicles in a vehicle dispatch management system according to an embodiment of the present invention. More specifically, FIG. 5A shows a control device 500a mounted on a manned vehicle V_NAD, and FIG. 5B shows a control device 500b mounted on an unmanned vehicle V_AD.

[0049] As shown in FIG. 5A, the control device 500a includes, for example, a location information acquisition unit 510, a communication unit 520, and a user interface unit (denoted as "UI" in the drawing) 530.

[0050] The position information acquisition unit 510 acquires the position information of the vehicle V from the GPS system. The position information acquisition unit 510 passes the position information acquired from the GPS system to the communication unit 520 to transmit it to the vehicle dispatch management device 10.

[0051] The communication unit 520 is a communication interface for exchanging various information with the vehicle communication interface unit 160 of the vehicle dispatch management device 10. As one example, the communication unit 520 receives a transmission request for vehicle information transmitted from the vehicle communication interface unit 160, and in response thereto, transmits vehicle information including location information to the vehicle communication interface unit 160. As another example, the communication unit 520 receives a dispatch instruction transmitted from the vehicle communication interface unit 160 and passes it on to the user interface unit 530.

[0052] The user interface unit 530 displays various states of the vehicle V to the driver and accepts input from the driver regarding these states. For example, the user interface unit 530 displays dispatch instructions transmitted from the vehicle dispatch management device 10.

[0053] On the other hand, a control device 500b shown in Fig. 11(b) differs from the configuration of the control device 500a in that it further includes, for example, a travel route control unit 540 and a navigation database 550. Note that the user interface unit 530 of the unmanned vehicle V_AD can be used to provide various information to a user riding in the vehicle.

[0054] The driving route control unit 540 determines an actual driving route based on various road map information stored in the navigation database 550 in accordance with the vehicle dispatch plan provided by the vehicle dispatch management device 10. The driving route control unit 540 may also determine a driving route based on road traffic information acquired from the road traffic information management system 30. In other words, in the present disclosure, the vehicle dispatch plan created by the vehicle dispatch management device 10 based on a vehicle dispatch request includes a reference route and travel time connecting each intermediate point (boarding point and disembarking point), but the driving route according to actual road traffic conditions is left to the unmanned vehicle V_AD. Therefore, the driving route control unit 540 of the unmanned vehicle V_AD determines an actual driving route based on the vehicle dispatch plan by referring to its own navigation database 550. The control device 500b controls the autonomous driving of the unmanned vehicle V_AD in accordance with the driving route determined by the driving route control unit 540. The driving route control unit 540 can transmit driving data of the unmanned vehicle V_AD to the vehicle dispatch management device 10 via the communication unit 520.

[0055] The navigation database 550 stores navigation information for the autonomous driving of the vehicle V in the area covered by the vehicle dispatch service. The navigation information typically includes road traffic information, driving history information, and the like. The navigation database 550 of the unmanned vehicle V_AD is generally the same as the road map information database 12b described above in that it includes road map information, but differs from it in that the stored road map information and driving history information are updated based on the actual autonomous driving of the unmanned vehicle V_AD. The driving route control unit 540 updates the road map information and driving history information in the navigation database 550, for example, as the unmanned vehicle V_AD autonomously drives along the determined driving route. For example, the road map information can be detailed by updating. The navigation database 550 may also include, for example, a street view of the driving route photographed by the autonomously driving unmanned vehicle V_AD.

[0056] FIG. 6 is a sequence chart for explaining an outline of a vehicle dispatch service in a vehicle dispatch management system according to one embodiment of the present invention.

[0057] As shown in the figure, a user who wishes to use a vehicle dispatch service executes a vehicle dispatch app implemented in the terminal device 20 and inputs the necessary information for the vehicle dispatch request on a vehicle dispatch request screen displayed on the user interface, and the terminal device 20 then transmits the vehicle dispatch request to the vehicle dispatch management device 10 (S601). For example, a user who wishes to ride (reserve a vehicle) operates the vehicle dispatch app to input the boarding and disembarking locations, the number of passengers, etc. The boarding and disembarking locations can be selected, for example, from a geographical map displayed by the vehicle dispatch app. Alternatively, the boarding location may be the user's current location obtained using a GPS function installed in the user's smartphone.

[0058] When the vehicle dispatch management device 10 receives a vehicle dispatch request from the terminal device 20 (S602), it requests vehicles V in the target area to acquire vehicle information including location information (S603). In response to this, each vehicle V transmits vehicle information including its own location information acquired from the GPS system to the vehicle dispatch management device 10 (S604). Note that the acquisition and transmission of location information by the vehicle V may be performed periodically or in response to a transmission request from the vehicle dispatch management device 10. The vehicle dispatch management device 10 acquires the vehicle information including location information transmitted from the vehicle V.

[0059] Next, the vehicle dispatch management device 10 creates a vehicle dispatch plan for candidate vehicles v extracted based on the user's vehicle dispatch request and proposes this to the user (S605). That is, the vehicle dispatch management device 10 derives a route pattern based on the vehicle dispatch request and creates a vehicle dispatch plan for candidate vehicles v extracted based on the derived route pattern. At this time, the vehicle dispatch management device 10 determines the route characteristics of the operating route based on the vehicle dispatch request and specifies the vehicle performance of the candidate vehicles v, selects candidate vehicles v having vehicle performance that matches the route characteristics according to the vehicle performance requirement table, and extracts the vehicle dispatch plan. The vehicle dispatch management device 10 transmits an acceptance request including the contents of the vehicle dispatch plan to the terminal device 20 to propose the selected vehicle dispatch plan to the user.

[0060] When the terminal device 20 receives the request for approval of the vehicle dispatch plan, it displays it as a vehicle dispatch plan proposal screen on the user interface and prompts the user to accept or reject (accept or reject) the proposed vehicle dispatch plan (S606). The vehicle dispatch plan proposal screen may include, for example, the specific pick-up and drop-off locations where vehicle V will arrive and the expected arrival time. The user can input their acceptance or rejection of the proposed vehicle dispatch plan on the vehicle dispatch plan proposal screen. In response to the user's input of their acceptance or rejection on the vehicle dispatch plan proposal screen, the terminal device 20 transmits an acceptance or rejection notice to the vehicle dispatch management device 10 (S607), and the vehicle dispatch management device 10 receives the acceptance or rejection notice transmitted from the terminal device 20 (S608). For example, if the acceptance or rejection notice indicates acceptance of the vehicle dispatch plan, the vehicle dispatch management device 10 confirms the vehicle dispatch plan for vehicle V in accordance with the vehicle dispatch plan, transmits a confirmation notice of the vehicle dispatch reservation to the terminal device 20, and transmits a dispatch instruction to vehicle V in accordance with the vehicle dispatch plan (S609).

[0061] When the terminal device 20 receives the notification of confirmation of the vehicle dispatch reservation, it displays it on the user interface to inform the user that the vehicle dispatch reservation has been confirmed (S610). Meanwhile, when the vehicle V receives the dispatch instruction, it executes a vehicle dispatch service according to the vehicle dispatch plan (S611). That is, if the vehicle V to which the dispatch instruction has been given is an unmanned vehicle V_AD, the unmanned vehicle V_AD plans a specific driving route according to the vehicle dispatch plan and begins autonomous driving to head to the pick-up / drop-off point to pick up the user who made the dispatch request. Furthermore, if the vehicle V to which the dispatch instruction has been given is a manned vehicle V_NAD, the manned vehicle V_NAD displays, for example, on a navigation screen, a driving route according to the vehicle dispatch plan indicated in the dispatch instruction to navigate the driver. This realizes an on-demand vehicle dispatch service for the vehicle V in response to the user's dispatch request.

[0062] Then, when the operation of the vehicle V according to the vehicle dispatch plan based on the dispatch request is completed, the vehicle dispatch management device 10 stores the operation history information of the vehicle V in the operation history information database 12e (S612). The operation history information stored in the operation history information database 12e is used to determine the route characteristics of the vehicle V next time.

[0063] 7 is a flowchart illustrating an example of a vehicle dispatch management process performed by the vehicle dispatch management device according to one embodiment of the present invention. This process is realized by the vehicle dispatch management device 10 executing a vehicle dispatch management server program under the control of a processor, in cooperation with various hardware resources.

[0064] As shown in the figure, the vehicle dispatch management device 10 waits until a new vehicle dispatch request is received from a user (S701). Meanwhile, for example, a user wishing to ride inputs a vehicle dispatch request by operating a vehicle dispatch app on the user interface of the terminal device 20. When a vehicle dispatch request is received from the user (Yes in S701), the vehicle dispatch management device 10 requests each vehicle V to transmit vehicle information and acquires the vehicle information, including location information, transmitted from each vehicle V (S702).

[0065] Next, the dispatch management device 10 refers to the road map information database 12b based on the desired boarding and disembarking locations indicated in the dispatch request, and determines the boarding and disembarking locations (boarding and disembarking locations) where the user will actually board and disembark (S703).

[0066] Next, the vehicle dispatch management device 10 extracts one or more candidate vehicles v according to the determined boarding or disembarking locations (S704). For example, the vehicle dispatch management device 10 extracts a vehicle V in operation near the boarding location as a candidate vehicle v. A vehicle V in operation is a vehicle that is waiting at a waiting location in a state where it can provide service or is actually transporting passengers. This makes it possible to exclude, for example, a vehicle V that is located far from the boarding or disembarking location from the candidate vehicles v, thereby reducing the number of route patterns to be derived.

[0067] Next, the vehicle dispatch management device 10 derives a route pattern for each extracted candidate vehicle v by referring to the road map information database 12b (S705). As described above, the route pattern indicates a route that passes through all of the previously determined boarding and alighting points (waypoints) when new boarding and alighting points are added to the route. Next, the vehicle dispatch management device 10 creates a vehicle dispatch plan based on the derived route pattern (S706). As described above, the route pattern can be expressed as a lattice structure of links / nodes (roads) and nodes (intersections). The vehicle dispatch plan includes a waiting location that serves as a starting point, a waiting location that serves as an end point, and a travel route for the route pattern. A new vehicle dispatch plan is created for vehicle V waiting at a waiting location. In addition, the vehicle dispatch plan for vehicle V currently operating according to an already set vehicle dispatch plan is updated based on the derived route pattern.

[0068] Next, the vehicle dispatch management device 10 narrows down the vehicle dispatch plans (candidate vehicles v) by excluding vehicle dispatch plans that meet predetermined exclusion conditions from the created vehicle dispatch plans for candidate vehicles v (S707). For example, the vehicle dispatch management device 10 excludes vehicle dispatch plans for candidate vehicles v whose cruising distance is less than a predetermined threshold. This eliminates candidate vehicles v that do not satisfy the user's vehicle dispatch request. Furthermore, in the present disclosure, the vehicle dispatch management device 10 narrows down the vehicle dispatch plans by selecting candidate vehicles v whose vehicle performance is compatible with the route characteristics of the operation route based on the vehicle dispatch request. When multiple candidate vehicles v whose vehicle performance is compatible with the route characteristics are extracted, the vehicle dispatch management device 10 may select the candidate vehicle v with the lowest or lowest vehicle performance score.

[0069] Next, the vehicle dispatch management device 10 proposes the contents of the selected vehicle dispatch plan to the user (S708). That is, the vehicle dispatch management device 10 transmits the contents of the created current vehicle dispatch plan to the terminal device 20, and in response, the terminal device 20 displays the contents on the user interface and prompts the user to accept or reject the vehicle dispatch plan.

[0070] The vehicle dispatch management device 10 determines whether or not the proposed vehicle dispatch plan has been accepted by the user (S709). If the proposed vehicle dispatch plan has been accepted by the user (Yes in S709), the vehicle dispatch management device 10 confirms the current vehicle dispatch plan (S710). The vehicle dispatch management device 10 stores the confirmed vehicle dispatch plan in the vehicle dispatch plan database 12d. Next, the vehicle dispatch management device 10 transmits a notification of confirmation of the vehicle dispatch reservation to the terminal device 20, and transmits a dispatch instruction based on the vehicle dispatch plan to the vehicle V (S711).

[0071] On the other hand, if the vehicle dispatch management device 10 receives a non-acceptance (rejection) from the user in response to the proposed vehicle dispatch plan (No in S709), it cancels the current vehicle dispatch plan based on the user's vehicle dispatch request (S710). In this case, the vehicle dispatch management device 10 returns the temporarily held vehicle dispatch plan used to recreate the vehicle dispatch plan to the original held vehicle dispatch plan. If the user desires a different vehicle dispatch service, the user will make a new vehicle dispatch request.

[0072] 8 is a flowchart illustrating an example of a vehicle dispatch management process performed by a vehicle dispatch management device according to an embodiment of the present invention. More specifically, this is a flowchart illustrating the details of the vehicle dispatch plan narrowing process (S707) shown in FIG.

[0073] As shown in the figure, the vehicle dispatch management device 10 identifies links / nodes that constitute the travel route in the created vehicle dispatch plan based on road map information associated with the route pattern derived by the travel route planning unit 150 (S801). Next, the vehicle dispatch management device 10 calculates a score based on the risk factor of each identified link / node, and determines the route characteristics of the travel route based on the calculated score (S802). The risk factor of each link / node is obtained based on the road map information associated with the route pattern derived by the travel route planning unit 150 and road traffic information obtained from the road traffic information management system 30. The vehicle dispatch management device 10 may also calculate the score based on meteorological information for the area.

[0074] Next, the vehicle dispatch management device 10 refers to the vehicle information database 12c, acquires vehicle information of the candidate vehicle v, and identifies the vehicle performance based on the attribute information, vehicle performance information, etc. included therein (S803). For example, the vehicle performance of a vehicle V equipped with a sensing function such as a high-resolution image sensor and an advanced object recognition function will have a higher vehicle performance score than a vehicle V without such a function.

[0075] Next, the vehicle dispatch management device 10 narrows down and selects candidate vehicles v having vehicle performance that matches the determined route characteristics. Specifically, first, the vehicle dispatch management device 10 excludes candidate vehicles v that do not satisfy the traffic conditions of the links / nodes of the travel route (S804). In other words, if a vehicle V cannot travel on roads with width or height restrictions on the travel route, it cannot travel to the destination in the first place, so the vehicle dispatch management device 10 excludes such vehicles V from the candidate vehicles v. Traffic conditions include, for example, road width and height restrictions, as well as weight restrictions and restrictions on turning radius at intersections, but are not limited to these. This makes it possible to prevent a vehicle V whose vehicle attributes are incompatible with the travel route from being assigned.

[0076] Next, the vehicle dispatch management device 10 refers to the vehicle performance requirement table and extracts candidate vehicles v that match the risk factors of the links / nodes on the travel route (S805). For example, in the vehicle performance requirement table shown in Figure 4, if the risk factor of the link / node is pedestrians running out into the road, the candidate vehicles v are required to have a sensing function, an object identification function, an automatic emergency braking function, and an automatic collision avoidance function. Therefore, the vehicle dispatch management device 10 narrows down the candidate vehicles v to those that have these functions.

[0077] Next, the vehicle dispatch management device 10 determines whether the narrowed-down candidate vehicle v is one vehicle (S806). If the vehicle dispatch management device 10 determines that the narrowed-down candidate vehicle v is one vehicle (Yes in S806), the vehicle dispatch management device 10 selects the candidate vehicle v as the vehicle V to be proposed to the user (S807).

[0078] On the other hand, if the vehicle dispatch management device 10 determines that there is more than one narrowed-down candidate vehicle v (No in S806), it selects the candidate vehicle v with the lowest vehicle performance score (S808).

[0079] In this way, when the vehicle dispatch management device 10 receives a vehicle dispatch request from a user, it creates a vehicle dispatch plan for candidate vehicles v extracted in accordance with the vehicle dispatch request, determines route characteristics of the operating route in the vehicle dispatch plan, acquires the vehicle performance of the candidate vehicles V, selects candidate vehicles v having vehicle performance that matches the determined route characteristics as specific vehicles V, and proposes this vehicle dispatch plan to the user. As a result, the user is assigned a vehicle V having vehicle performance that matches the route characteristics, allowing the vehicle V to be operated safely and reliably, thereby improving the level of service (LoS).
