Description

[Technical Field]

[0001] The present invention relates to a vehicle allocation management device and a vehicle allocation management method. [Background technology]

[0002] In order to capture a getaway vehicle carrying a criminal suspect who is suspected of committing a crime, etc., emergency vehicles such as police vehicles that have been called in to the scene often pursue the getaway vehicle. In such situations, ordinary vehicles other than emergency vehicles must take steps to avoid obstructing the emergency vehicle's passage.

[0003] For example, the following Patent Document 1 discloses a technology for moving and stopping ordinary vehicles near the shoulder of a road based on the current position of the emergency vehicle and the current positions of ordinary vehicles other than the emergency vehicle when the emergency vehicle is traveling in an emergency. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-166412 Summary of the Invention [Problem to be solved by the invention]

[0005] The technology shown in Patent Document 1 simply moves and stops ordinary vehicles near the shoulder of the road so as not to interfere with the emergency movement of emergency vehicles, and does not cooperate with police activities, such as preventing the escape of a criminal suspect's getaway vehicle.

[0006] In addition, because secondary damage such as being involved in a personal accident or crime caused by a criminal suspect is expected, special consideration is required when actively cooperating with police activities. On the other hand, in the case of autonomous vehicles (unmanned vehicles) that have not yet been allocated to users in mobility services, secondary damage can be minimized even if they cooperate with police activities to prevent the escape of a criminal suspect's getaway vehicle, as long as it does not interfere with the operation of police emergency vehicles.

[0007] Therefore, an object of the present invention is to provide a vehicle dispatch management device and a vehicle dispatch management method that enable cooperation with police activities using vehicles provided for vehicle dispatch services in mobility services.

[0008] More specifically, the present invention aims to provide a vehicle dispatch management device and a vehicle dispatch management method that enable cooperation with police activities, such as preventing the escape of vehicles carrying criminal suspects, using autonomous vehicles provided for vehicle dispatch services in mobility services, to the extent that the operation of emergency vehicles such as police vehicles is not obstructed. [Means for solving the problem]

[0009] The present invention, which aims to solve the above problems, comprises the following invention-specifying matters and technical features.

[0010] According to one aspect, the present invention provides a vehicle dispatch management device that manages a vehicle dispatch service for a plurality of vehicles in a predetermined service area. The vehicle dispatch management device includes a vehicle information database that stores vehicle information for each of the plurality of vehicles, and a vehicle dispatch planning unit that creates a vehicle dispatch plan based on the vehicle information database. The vehicle dispatch planning unit includes a vehicle information acquisition unit that acquires the vehicle information from each of the plurality of vehicles, a vehicle selection unit that selects a vehicle to be dispatched to a user from the plurality of vehicles based on the user's dispatch request, a vehicle dispatch plan creation unit that creates the vehicle dispatch plan for the selected vehicles, and a vehicle dispatch instruction unit that issues dispatch instructions to the vehicles in accordance with the vehicle dispatch plan. The vehicle selection unit references the vehicle information database based on emergency information related to tracking of the fleeing vehicle, and selects a vehicle from the plurality of vehicles that has not yet been dispatched to the user as a cooperating vehicle. The vehicle dispatch plan creation unit creates the vehicle dispatch plan so that some of the cooperating vehicles are deployed at specific deployment points along the escape route of the fleeing vehicle. The vehicle allocation instruction unit issues movement instructions (task instructions) to the cooperation vehicles so that some of the cooperation vehicles are deployed to the specific deployment points in accordance with the vehicle allocation plan.

[0011] The present invention also provides a vehicle allocation management method using a vehicle allocation management device that manages vehicle allocation in response to a vehicle allocation request, a computer program for executing the method, and a recording medium on which the method is non-temporarily recorded.

[0012] In this disclosure, a "system" refers to a logical collection of multiple devices (or functional modules that realize specific functions), regardless of whether each device or functional module is contained within a single housing. [Effects of the Invention]

[0013] According to the present invention, cooperation with police activities becomes possible using autonomous vehicles in mobility services. In particular, according to the present invention, cooperation with police activities becomes possible by using autonomous vehicles in mobility services to prevent the escape of a criminal suspect's getaway vehicle to the extent that it does not interfere with the movement of emergency vehicles such as police vehicles, while preventing the occurrence of secondary damage.

DETAILED DESCRIPTION OF THE INVENTION

[0016] 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., combinations of the 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.

[0017] FIG. 1 is a diagram illustrating an example of a schematic configuration 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 connected to each other so as to be able to communicate with each other via a communication network N. 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. The vehicle dispatch management system 1 provides, for example, a vehicle dispatch service using multiple vehicles V for a certain area. In the present disclosure, the vehicle V is assumed to be an autonomously driven vehicle without a driver.

[0018] The vehicle dispatch management system 1 may also cooperate with police-related organizations (not shown). Police-related organizations are, for example, administrative agencies such as police that crack down on violators in accordance with traffic laws and regulations, and may vary depending on the legal system of each country. For example, vehicles of police-related organizations (hereinafter referred to as "police vehicles") often track vehicles driven by criminal suspects and fleeing the scene (hereinafter referred to as "fugitive vehicles"). In the present disclosure, in a case where a police vehicle tracks a fleeing vehicle, the vehicle dispatch management system 1, under the control of the vehicle dispatch management device 10, estimates the driving route of the fleeing vehicle (i.e., the escape route) and issues a movement instruction (operation instruction) to a vehicle V that is not provided for a vehicle dispatch service to deploy the vehicle V along the estimated escape route in order to cooperate with the police-related organizations. A vehicle V that is not provided for a vehicle dispatch service refers to a vehicle that has not yet been dispatched to a user or is waiting after completing a vehicle dispatch service. Hereinafter, this vehicle will be referred to as a "cooperative vehicle" from the perspective of cooperation with the police-related organizations.

[0019] 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 of ​​the vehicle dispatch service (hereinafter referred to as the "service target area"). The service target area may be divided into several areas (sub-areas). The vehicle dispatch management device 10, for example, implements 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. In particular, the vehicle dispatch management server program of the present disclosure includes a subprogram or module for extracting, under specified conditions, vehicles V that have not yet been dispatched to a user as cooperating vehicles for police-related agencies and deploying them along an escape route.

[0020] The vehicle dispatch management device 10 includes various databases 12 that accumulate and manage data necessary to realize such a vehicle dispatch service. The databases 12 may include, for example, a user information database 12a, a road map information database 12b, a vehicle information database 12c, and a vehicle dispatch plan database 12d (see FIG. 2). The databases 12 may be configured as part of the vehicle dispatch management device 10, or all or part of the databases 12 may be configured separately from the vehicle dispatch management device 10.

[0021] Generally speaking, under normal circumstances, the vehicle allocation management device 10 receives a vehicle allocation request from a user who wishes to allocate a vehicle V to a destination, refers to the vehicle information database 12c based on the vehicle allocation request, extracts a vehicle V to be allocated to the user from among multiple vehicles V, creates a vehicle allocation plan for the vehicle, and proposes the created vehicle allocation plan to the user. The vehicle allocation management device 10 confirms the proposed vehicle allocation plan upon the user's consent to the proposed vehicle allocation plan, and issues a vehicle allocation instruction to the vehicle V in accordance with the confirmed vehicle allocation plan.

[0022] The vehicle dispatch plan includes a driving route that specifies the route from the location where vehicle V is waiting (starting waiting location), passing through several points (boarding and disembarking points) along the way where users get on and off, to the final waiting location (which is not necessarily the same as the initial waiting location). If vehicle V is waiting, the vehicle dispatch plan is created anew based on the received vehicle dispatch request, and if vehicle V is in operation, it can be updated based on the vehicle dispatch request. A vehicle dispatch plan can also be created when vehicle V is a cooperative vehicle for police-related agencies.

[0023] In the present disclosure, when emergency information related to the pursuit of a fleeing vehicle is issued by a police-related agency, the vehicle dispatch management device 10 refers to the vehicle information database 12c and extracts a vehicle V that has not yet been dispatched to a user as a collaborating vehicle in order to cooperate with the police-related agency. Next, the vehicle dispatch management device 10 estimates the escape route of the fleeing vehicle based on the emergency information and instructs the collaborating vehicle to move so that the collaborating vehicle is deployed along the estimated escape route. This makes it possible to limit the escape route of the fleeing vehicle, making it easier for police officials to capture the fleeing vehicle and the criminal suspect.

[0024] Vehicle V is a vehicle registered in the vehicle information database 12c that is provided for use by users in the vehicle dispatch service. Vehicle V is an autonomous vehicle (unmanned vehicle) operated by an autonomous driving system, and the so-called autonomous driving level does not matter. Furthermore, the vehicle type of vehicle V (e.g., sedan, minivan, SUV, etc.) does not matter. In the present disclosure, vehicle V is divided into vehicles that can be provided as cooperation vehicles and vehicles that cannot be provided as cooperation vehicles. Furthermore, vehicles that can be provided as cooperation vehicles are divided into vehicles that can be deployed and vehicles that cannot be deployed.

[0025] The vehicle V includes a control device CTL and a user interface UI that control the vehicle V itself or its onboard equipment in accordance with dispatch instructions from the vehicle dispatch management device 10. Although not shown, the control device CTL includes a processor, memory, and the like, and realizes various functions by executing control programs. Furthermore, under the control of the control device CTL, the vehicle V acquires driving management information necessary for autonomous driving from various cameras and sensors and transmits this information to the vehicle dispatch management device 10. The vehicle dispatch management device 10 monitors and controls the driving of the vehicle V in accordance with the driving management information transmitted from the vehicle V. The driving management information includes, for example, video and audio information about the surroundings of the vehicle V obtained by a camera / microphone, spatial recognition information (point cloud information) obtained by spatial recognition sensors such as LiDAR and RADAR, geographical position information of the vehicle V obtained by a GPS system, and status information obtained by status monitoring sensors that monitor the status of the vehicle V, each device, and each component. In the present disclosure, the vehicle V, under the instruction of the vehicle dispatch management device 10, can collect information about the surrounding environment as a form of driving management information as a cooperating vehicle, even when not dispatched to a user (standby state). This makes it possible to use cooperating vehicles that are not deployed on the getaway vehicle's getaway route to monitor the getaway vehicle's escape and prepare for any unforeseen circumstances.

[0026] Furthermore, vehicle V may be equipped with an external human-machine interface (eHMI) to notify the public (e.g., passersby and drivers of other vehicles) when it is cooperating with police agencies as a cooperating vehicle. A display and a speaker are examples of eHMI. This allows nearby passersby and drivers to know that police activities are being conducted and that the vehicle is cooperating, thereby promoting understanding of the cooperating vehicle that is obstructing traffic flow.

[0027] 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 making a reservation for a ride in the vehicle V.

[0028] 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 various monitoring equipment installed on roads and from a control device CTL installed in the vehicle V, and manages road traffic information by processing and editing the data in an integrated manner. The monitoring equipment includes, but is not limited to, live cameras and vehicle sensors. The edited road traffic information may include, for example, information on road closures and detour routes, and the travel time between points via a specific route. The road traffic information management system 30 appropriately provides road traffic information to the vehicle dispatch management device 10 and the vehicle V. In addition to weather information, traffic information, and road regulation information, the road traffic information management system 30 may provide the vehicle dispatch management device 10 with video information from live cameras, audio information from sound-collecting microphones, and sensor information from vehicle sensors obtained from the monitoring equipment as driving management information. This enables the vehicle dispatch management device 10 to appropriately monitor and guide the vehicle V according to the driving management information.

[0029] 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 may be configured as a functional configuration model including functional components such as a front-end processing unit 110, a vehicle dispatch planning unit 120, and a vehicle communication unit 130. Furthermore, as described above, the vehicle dispatch management device 10 includes various databases 12. This functional model is realized when the vehicle dispatch management device 10 executes 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 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 terminal device 20 and a control device CTL in the vehicle V.

[0030] 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 (gender, age, address, etc.), and information about service usage status. 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.

[0031] The road map information database 12b stores road map information for the target area of ​​the vehicle dispatch service. The road map information includes map data on addresses, place names, road networks (links and nodes), various facilities (e.g., police stations, etc.), etc. The road map information also includes information necessary for searching for a driving route, such as road information, feature information, and environmental information. The road information includes road attribute information such as road type (e.g., community road, arterial road, etc.), road width, pedestrian / vehicle divider, median, and lane.

[0032] The vehicle information database 12c stores information (vehicle information) about vehicles V available for use by users. For example, as shown in FIG. 3 , the vehicle information includes information about a vehicle ID, vehicle attributes (vehicle registration number, vehicle model, maximum occupancy / maximum load capacity, automated driving level, etc.), vehicle characteristics, other specifications (length, width, height, weight, etc.), a current vehicle dispatch plan, a current location, and a current status (service status, remaining battery capacity (cruising range), number of occupants, etc.). Vehicle information, such as location information, acquired from the vehicle V via the communication control unit 140 may be updated as needed. In the present disclosure, the vehicle attributes include cooperative vehicle information. The cooperative vehicle information includes, for example, information about whether the vehicle V can be deployed and / or monitored as a cooperative vehicle. More specifically, a “deployable” vehicle V is a vehicle provided as a cooperative vehicle that can be deployed to a specific deployment point, and a “monitoring-enabled” vehicle V is a vehicle that cannot be deployed to a specific deployment point but is provided as a cooperative vehicle capable of monitoring. Vehicle V that cannot be provided as a cooperation vehicle is indicated as "non-cooperation."

[0033] The vehicle allocation plan database 12d stores a vehicle allocation plan for each vehicle V created by the vehicle allocation plan unit 120 based on a vehicle allocation request. As described above, the vehicle allocation plan includes a driving 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 (departure and arrival points), an estimated arrival time at each intermediate point, etc. Furthermore, the vehicle allocation plan for a cooperating vehicle includes a driving route from a waiting location serving as a starting point to a specified stopping point, etc.

[0034] 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 accordance with a login request from a ride-hailing app on the user's terminal device 20. The front-end processing unit 110 also communicates with the terminal device 20 in order to respond to a ride-hailing request from the ride-hailing app on the user's terminal device 20.

[0035] The vehicle allocation planning unit 120 extracts candidate vehicles V from among the vehicles V that can operate in the target area based on the vehicle allocation request delivered from the front-end processing unit 110, and creates and / or updates the vehicle allocation plan. The vehicle allocation planning unit 120 proposes the created or updated vehicle allocation plan to the user via the front-end processing unit 110. When the proposed vehicle allocation plan is approved by the user, the vehicle allocation planning unit 120 finalizes the approved vehicle allocation plan, stores the finalized vehicle allocation plan in the vehicle allocation plan database 12d, and issues a dispatch instruction to the vehicles V of the vehicle allocation plan. Furthermore, the vehicle allocation planning unit 120 estimates the driving route of the getaway vehicle based on emergency information regarding the escape of the getaway vehicle issued by police-related agencies, and issues a movement instruction to the vehicle V that has not yet been assigned to the user to dispatch (deploy) the vehicle V as a cooperating vehicle along the estimated escape route.

[0036] The vehicle communication unit 130 exchanges various information with the vehicle V via the communication network N. For example, the vehicle communication unit 130 transmits a vehicle information transmission request to the vehicle V and receives vehicle information transmitted by the vehicle V in response to the request. The vehicle information includes, for example, location information of the vehicle V. The vehicle communication unit 130 also transmits dispatch instructions or movement instructions to the vehicle V according to the confirmed dispatch plan.

[0037] 4 is a block diagram showing details of a vehicle dispatch planning unit in a vehicle dispatch management device according to one embodiment of the present invention. As shown in the figure, the vehicle dispatch planning unit 120 includes, for example, a vehicle dispatch request acquisition unit 121, a driving route determination unit 122, a vehicle information acquisition unit 123, a vehicle selection unit 124, a vehicle dispatch plan creation unit 125, an emergency information acquisition unit 126, an escape route estimation unit 127, and a vehicle dispatch instruction unit 128.

[0038] The vehicle allocation request acquisition unit 121 acquires or accepts a vehicle allocation request from a user via the front-end processing unit 110. The time when the vehicle allocation request acquisition unit 1201 acquires a vehicle allocation request is the start time for counting various limit times for creating a vehicle allocation plan (for example, a boarding limit time and a disembarking limit time, which are the limit times for getting a user on or off).

[0039] The travel route determination unit 122 determines an optimal travel route based on the dispatch request. For example, the travel route determination unit 122 determines a travel route from the departure point to the destination by having the route search engine search for a route based on the boarding point (departure point) and disembarking point (destination) indicated in the dispatch request while referring to the road map information database 12b.

[0040] The vehicle information acquisition unit 123 acquires vehicle information from each vehicle V via the vehicle communication unit 130 at a predetermined timing. The vehicle information may include vehicle position information and remaining energy amount of the vehicle V. For example, the vehicle information acquisition unit 123 may periodically acquire vehicle information transmitted from each vehicle V, or may periodically or irregularly request a specific vehicle V to transmit vehicle information and acquire vehicle information transmitted from the specific vehicle V in response to the request. The vehicle information acquisition unit 123 stores the acquired vehicle information of each vehicle V in the vehicle information database 12c. The vehicle position information may be used to extract a vehicle V to be dispatched to a user based on its positional relationship with the driving route of the vehicle V, or to deploy a vehicle V as a cooperating vehicle based on its positional relationship with the escape route of the getaway vehicle.

[0041] The vehicle selection unit 124 extracts and selects a specific vehicle suited to the travel route from among a plurality of vehicles V. For example, the vehicle selection unit 124 first refers to the vehicle information database 12c, etc., and extracts vehicles V that are near the boarding location indicated in the dispatch request and based on the location information indicated by the vehicle information. Next, the vehicle selection unit 124 selects a vehicle V suited to the travel route from among the extracted vehicles V, taking into consideration constraints such as various limit allowable times.

[0042] The vehicle selection unit 124 also extracts and selects, as cooperating vehicles, vehicles V that can cooperate with police-related organizations. For example, based on the emergency information, the vehicle selection unit 124 references the vehicle information database 12c, etc., and extracts and selects, as cooperating vehicles, vehicles V that are waiting and have not yet been dispatched to the user and whose cooperation vehicle information indicates "available for deployment" and / or "available for monitoring." The vehicle selection unit 124 may, for example, select, as cooperating vehicles, a number of vehicles V corresponding to the escape route of the fleeing vehicle estimated based on the emergency information. The vehicle selection unit 124 may also, for example, exclude, from the cooperating vehicles, vehicles V located on the opposite side of the escape direction of the fleeing vehicle. This prevents a situation in which all waiting vehicles V become cooperating vehicles, leaving no vehicles V to be dispatched to the user and causing the vehicle dispatch service to stop. The vehicle dispatch management device 10 may also, as necessary, extract, as a cooperating vehicle, a vehicle V that dropped off the user at the destination. Furthermore, the vehicle selection unit 124 may, for example, preferentially select a vehicle V having a high rigidity, medium-sized or larger vehicle, rather than a small vehicle having a low rigidity, in terms of vehicle attributes. This may discourage a fleeing vehicle from physically contacting a deployed cooperating vehicle, and even if contact does occur, damage can be minimized.

[0043] Furthermore, the vehicle selection unit 124 updates the selection of cooperating vehicles based on the latest escape route of the fleeing vehicle estimated based on the emergency information. For example, when the escape route of the fleeing vehicle is updated, the vehicle selection unit 124 newly selects or excludes a waiting vehicle V based on the updated escape route and / or the current location of the fleeing vehicle. This makes it possible to efficiently and flexibly select cooperating vehicles even in response to unexpected changes in the escape route of the fleeing vehicle.

[0044] The vehicle allocation plan creation unit 125 creates a vehicle allocation plan for the selected vehicle V based on the travel route. As described above, the vehicle allocation plan includes a travel route that defines a route from the location where the vehicle V is waiting (the waiting location that is the starting point), via several points (boarding and disembarking points) along the way where the user gets on and off, to the waiting location that is the end point (which is not necessarily the same as the initial waiting location). If the vehicle V is waiting, the vehicle allocation plan creation unit 125 creates a new vehicle allocation plan based on the vehicle allocation request, and if the vehicle V is in operation, it updates the vehicle allocation plan for the vehicle V stored in the vehicle allocation plan database 12d. The created vehicle allocation plan is transmitted to the user's terminal device 20, proposed to the user, and confirmed according to the user's acceptance of the vehicle allocation plan.

[0045] Furthermore, the vehicle allocation plan creation unit 125 creates and confirms a vehicle allocation plan for a vehicle V selected as a cooperative vehicle in accordance with the cooperative vehicle information. For example, the vehicle allocation plan creation unit 125 creates and confirms a vehicle allocation plan for the cooperative vehicle based on the escape route of the fleeing vehicle estimated by the escape route estimation unit 127, which will be described later. The vehicle allocation plan for the cooperative vehicle includes, for example, a driving route from a current waiting location to a specified specific deployment point. The vehicle allocation plan creation unit 125 may create a vehicle allocation plan by matching the vehicle V with a specific deployment point so that the travel distance between the current location (waiting location) of the selected vehicle V and the specific deployment point is shortest. Furthermore, the vehicle allocation plan creation unit 125 may create a vehicle allocation plan for a vehicle V selected as a cooperative vehicle that can only monitor, in which the vehicle V waits at the location.

[0046] Furthermore, the vehicle allocation plan creation unit 125 may create or update a vehicle allocation plan for cooperating vehicles based on the updated escape route each time the escape route is updated based on the current location of the fleeing vehicle. This allows the deployment of cooperating vehicles to be updated in accordance with the updated vehicle allocation plan. For example, a cooperating vehicle that was already deployed at a certain location may be deployed to a new deployment location in accordance with the updated vehicle allocation plan. Alternatively, a new vehicle allocation plan may be created for a newly added cooperating vehicle. This allows the deployment of cooperating vehicles to be flexibly changed even in response to unexpected changes in the escape route of the fleeing vehicle.

[0047] Furthermore, for example, the vehicle allocation plan creation unit 125 may create a vehicle allocation plan that specifies the vicinity of intersections and / or junctions of each road connected to the estimated escape route as specific deployment locations for cooperating vehicles. This more effectively restricts the escape route of the getaway vehicle while fleeing, allows the getaway vehicle to be guided in the direction expected by police agencies, and makes it easier for police officers to capture the getaway vehicle and the criminal suspect. In this case, the vehicle allocation plan creation unit 125 may create each vehicle allocation plan so that multiple cooperating vehicles are deployed at each intersection and / or junction. This more reliably restricts the escape route of the getaway vehicle while fleeing, and also prevents secondary damage to ordinary citizens.

[0048] The emergency information acquisition unit 126 acquires emergency information issued in real time from police-related organizations as needed. The emergency information is, for example, emergency information related to the pursuit of a fleeing vehicle, and includes, for example, information on the external characteristics of the fleeing vehicle (such as the type and color), the number and characteristics of criminal suspects in the vehicle, as well as their locations and fleeing directions.

[0049] The escape route estimation unit 127 estimates the escape route of the fleeing vehicle by referring to the road map information database 12b, etc., based on the acquired emergency information. This makes it possible to select a vehicle V that has been waiting in response to a user's vehicle dispatch request near the estimated driving route as a cooperating vehicle, and to more quickly deploy cooperating vehicles along the escape route of the fleeing vehicle and restrict the escape route. Furthermore, the escape route estimation unit 127 can update the escape route as needed based on the current location of the fleeing vehicle while it is fleeing. This makes it possible to effectively deploy cooperating vehicles along the escape route and restrict the escape route even in the event of an unexpected escape by the fleeing vehicle.

[0050] The escape route estimation unit 127 may also determine a new escape route for the fleeing vehicle by adding a guidance route leading to a specific facility (e.g., a police station) to the estimated escape route. For example, the escape route estimation unit 127 references the road map information database 12b and determines a route leading to a police station located ahead of the fleeing vehicle's escape direction as a guidance route, and adds this to the current escape route to determine the new escape route. By deploying cooperating vehicles along the escape route, the fleeing vehicle can be guided to the vicinity of the police station, making it easier for police officers to capture the fleeing vehicle and the criminal suspect. In this case, the escape route estimation unit 127 may determine a route including major roads other than community roads as a guidance route. This prevents the fleeing vehicle from entering community roads during the escape, protects ordinary citizens from the dangerous driving of the fleeing vehicle, and guides the fleeing vehicle to the vicinity of the police station, thereby preventing secondary damage.

[0051] The vehicle dispatch instruction unit 128 issues a dispatch instruction or a movement instruction to the corresponding vehicle V according to the confirmed vehicle dispatch plan. The control device CTL of the vehicle V that receives the dispatch instruction or the movement instruction determines, for example, a detailed actual driving route according to the driving route in the vehicle dispatch plan and controls the vehicle V so that the vehicle V autonomously drives along the actual driving route. As an example, under normal circumstances, the vehicle dispatch instruction unit 128 issues a dispatch instruction to the vehicle V to pick up the user at a boarding / disembarking point and travel to the destination in accordance with the user's dispatch request. As another example, in response to the issuance of emergency information, the vehicle dispatch instruction unit 128 issues a movement instruction to the cooperating vehicle to travel to a specified specific deployment point. In this case, the vehicle dispatch instruction unit 128 may issue a movement instruction to the cooperating vehicle according to the vehicle dispatch plan so that one or more cooperating vehicles are deployed near intersections and / or branch points of each road connected to the escape route. In other words, the cooperating vehicles form barricades along the escape route. This will more effectively restrict the escape routes of getaway vehicles while they are fleeing, making it easier for police officers to capture getaway vehicles and criminal suspects.

[0052] Furthermore, the vehicle allocation instruction unit 128 can issue movement instructions to the cooperating vehicles as needed so that the deployment of the cooperating vehicles is updated based on a vehicle allocation plan based on the latest updated escape route. For example, when the escape route is updated by the escape route estimation unit 127, the vehicle allocation instruction unit 128 instructs the cooperating vehicles already deployed at a certain location to move to a new specific deployment location, or instructs the newly added cooperating vehicles to move to a specified specific deployment location. This makes it possible to restrict the driving route in real time even in the event of an unexpected escape by the escape vehicle.

[0053] Furthermore, the vehicle dispatch instruction unit 128 may issue a movement instruction to the cooperating vehicle to avoid the emergency movement of the police vehicle involved in the fleeing vehicle. The police vehicle involved in the fleeing vehicle may be, for example, a police vehicle pursuing the fleeing vehicle or a police vehicle directing traffic in connection with the pursuit of the fleeing vehicle. For example, the cooperating vehicle that receives the movement instruction will avoid traveling on roads on which the police vehicle is scheduled to travel. This makes it possible to avoid the police activities of the police vehicle pursuing the fleeing vehicle being hindered by the cooperating vehicle.

[0054] Furthermore, the vehicle dispatch instruction unit 128 may instruct the cooperating vehicles selected by the vehicle selection unit 124 that were not deployed along the getaway route because they were "unavailable for deployment" to monitor the environment surrounding the vehicle and transmit environmental information related to the surrounding environment. Upon receiving such an instruction, the vehicle V may transmit the surrounding environment information collected by various cameras and sensors to the vehicle dispatch management device 10. The vehicle dispatch management device 10 may provide the collected surrounding environment information to, for example, police-related agencies. This allows surrounding environment information to be collected from a wider range and more points, which can be useful in capturing the getaway vehicle.

[0055] In this way, the cooperating vehicles that have received a movement instruction from the vehicle allocation instruction unit 128 based on the emergency information move to a specific deployment point designated on the escape route, thereby restricting the escape route of the escape vehicle. When the emergency is lifted, the vehicle allocation plan creation unit 125 terminates the vehicle allocation plan for the cooperating vehicles, and in response, the vehicle allocation instruction unit 128 instructs the cooperating vehicles to return to normal operation.

[0056] In the above example, the vehicle allocation plan creation unit 125 creates a vehicle allocation plan for cooperating vehicles based on emergency information, and the vehicle allocation instruction unit 128 instructs the cooperating vehicles to move in accordance with the vehicle allocation plan. However, this is not limited to this, and for example, the vehicle allocation instruction unit 128 may immediately instruct the cooperating vehicles to move based on emergency information.

[0057] 5 is a flowchart for explaining an example of emergency response processing by a vehicle dispatch control device according to one embodiment of the present invention. The emergency response processing is realized by the vehicle dispatch control device 10 executing a vehicle dispatch control server program under the control of a processor, thereby cooperating with various hardware resources.

[0058] As shown in the figure, the vehicle dispatch management device 10 monitors whether emergency information issued by a police-related agency has been acquired (S501). For example, if a police-related agency recognizes that a crime has occurred and a criminal suspect is attempting to flee in a vehicle, the police-related agency issues emergency information related to the tracking of the fleeing vehicle. The emergency information is, for example, emergency information related to the tracking of the fleeing vehicle, and includes, for example, information on the external characteristics of the fleeing vehicle (such as the model and color), the number and characteristics of the criminal suspects aboard, as well as their location and escape direction. When the vehicle dispatch management device 10 detects and acquires such emergency information (Yes in S501), the vehicle dispatch management device 10 estimates the escape route of the fleeing vehicle based on the acquired emergency information (S502). In this case, the vehicle dispatch management device 10 may determine, as a new escape route for the fleeing vehicle, a route obtained by adding a guide route leading to a specific facility, such as a police station, to the estimated escape route.

[0059] Next, the vehicle dispatch management device 10 refers to the vehicle information database 12c based on the estimated escape route, and extracts and selects vehicles V that can cooperate with police-related agencies as cooperative vehicles (S503). A cooperative vehicle V (cooperative vehicle) is a waiting vehicle V that has not yet been dispatched to a user, and whose cooperative vehicle information is "available for deployment" and / or "available for monitoring."

[0060] Next, the vehicle allocation management device 10 creates and confirms a vehicle allocation plan for each selected cooperative vehicle based on the estimated escape route, etc. (S504). For example, the vehicle allocation management device 10 determines a specific deployment point for each cooperative vehicle based on the geographical relationship between the escape route and the current location of the cooperative vehicle, and creates a vehicle allocation plan including a driving route from the current waiting location to the specific deployment point. Typically, the cooperative vehicle is deployed at an intersection or branch point on the escape route. Next, the vehicle allocation management device 10 issues a movement instruction to the corresponding vehicle V in accordance with the confirmed vehicle allocation plan (S505). The cooperative vehicle that received the movement instruction determines a detailed actual driving route, for example, according to the driving route in the vehicle allocation plan, and autonomously drives along the actual driving route to the specific deployment point. In addition, the vehicle allocation management device 10 may instruct the cooperative vehicle to notify the outside (e.g., pedestrians, drivers of other vehicles, etc.) that it is cooperating with police-related agencies, for example, using an eHMI. This notifies nearby passersby and drivers that police are working and cooperating, which can promote understanding of the cooperating vehicle that is obstructing traffic flow. In addition, the vehicle dispatch management device 10 may instruct cooperating vehicles that cannot be deployed to monitor the surroundings on the spot.

[0061] After issuing an instruction to the cooperating vehicles to move, the vehicle dispatch management device 10 monitors whether the emergency situation has been lifted by, for example, apprehending the criminal suspect (getaway vehicle) (S506). If the vehicle dispatch management device 10 determines that the emergency situation has not been lifted due to continued reports from police agencies (No in S506), the vehicle dispatch management device 10 then determines whether the emergency situation information has been updated (S507). If the vehicle dispatch management device 10 determines that the emergency situation information has not been updated (No in S507), it repeats the above processing until the emergency situation is lifted. If the vehicle dispatch management device 10 determines that the emergency situation has been lifted (Yes in S506), it issues an instruction to release all cooperating vehicles deployed at specific deployment points (S508).

[0062] On the other hand, if the vehicle dispatch management device 10 determines that the emergency information has been updated (Yes in S507), the vehicle dispatch management device 10 newly estimates and updates the escape route of the fleeing vehicle based on the updated emergency information (S502). Next, the vehicle dispatch management device 10 updates the cooperating vehicles based on the updated escape route (S503) and updates the dispatch plan for the cooperating vehicles (S504). Then, it issues a movement instruction to the cooperating vehicles (S505). The vehicle dispatch management device 10 repeats the above process until the emergency information is lifted.

[0063] For example, assume that a vehicle dispatch service is being provided in a service area of ​​the vehicle dispatch management system 1, as shown in Fig. 6. In the figure, the shaded vehicles V are vehicles that have already been dispatched to users and are currently traveling to their destinations, while the other vehicles V are waiting vehicles parked at designated waiting locations or waiting vehicles that are cruising. In this situation, assume that a crime has occurred and emergency information has been issued regarding the pursuit of the fleeing vehicle.

[0064] When the vehicle dispatch management device 10 acquires the emergency information, it estimates an escape route based on the emergency information and determines the escape route including a guide route to the police station, as shown in FIG. 7. Next, the vehicle dispatch management device 10 extracts an appropriate vehicle V from among the waiting vehicles as a cooperating vehicle. At this time, the vehicle dispatch management device 10 may extract the vehicle V that dropped off the user at the destination as a cooperating vehicle, if necessary. Then, the vehicle dispatch management device 10 issues a movement instruction to the cooperating vehicle so that the cooperating vehicle is deployed along the escape route, and in response, the cooperating vehicle moves to the deployment point. In the same figure, the cooperating vehicle is shown deployed at an intersection or branch point on the escape route, particularly so as to restrict the escape direction of the fleeing vehicle.

[0065] As described above, according to this embodiment, based on emergency information regarding the tracking of a fleeing vehicle issued by police-related agencies, a vehicle V that has not yet been assigned to a user is deployed as a cooperating vehicle along the fleeing vehicle's escape route, thereby restricting the fleeing vehicle's escape route and making it easier for police personnel to capture the fleeing vehicle and criminal suspects.
