Description

  The present invention relates to allocation of a plurality of vehicles capable of automatic driving.

  In recent years, various automatic driving techniques for dispatching a vehicle to a destination even when a driver is absent have been proposed. For example, in Patent Document 1, a guide line in which non-contact devices are incorporated at regular intervals is provided on a roadway, and a detector that performs wireless communication with the non-contact devices is mounted on the vehicle. There has been proposed a system in which the vehicle itself controls the driving so as to go to the destination while reading the position specifying data stored in the contact device and specifying the current position.

Japanese Patent No. 5289568

  A plurality of types of roles are set in advance for each of the plurality of vehicles that can be driven automatically, and a vehicle in which a necessary role is set according to the situation is assigned to a specific dispatch location from among these types. There is a request to want. With the technology of Patent Document 1, it is possible to specify the current position of a specific vehicle and automatically drive the vehicle to the dispatch location. However, it is necessary to manage all information such as which vehicle has a role set according to the situation and where the vehicle is currently located, and the above request In order to respond to this, there is a problem that the facilities and labor required for management increase. In particular, when there are a plurality of necessary roles according to the situation, there is a problem that the facilities and labor required for management become very large. In addition, since the current position of the vehicle changes with driving, there is a problem that a vehicle far from the dispatch location is dispatched and it takes a long time to complete the dispatch. Therefore, there is a demand for a technology that can suppress an increase in the time and time required for facilities and labor required for vehicle allocation and the time required for vehicle allocation.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms.

  According to one aspect of the present invention, a vehicle dispatch system (10) is provided. This vehicle dispatch system is required at a dispatch location among a plurality of vehicles (200, 200a) capable of automatic driving, each of which is set with at least one of a plurality of roles. A management device (100, 100a) that directs a vehicle having a specific role, which is a role, to the dispatch location, and the management device includes information indicating the specific role and rushes to the dispatch location A driving request transmission unit (115 + rs) that broadcasts a driving request signal for requesting driving; receiving the driving request signal among the plurality of vehicles, and sending a driving enable signal as a response to the driving request signal A driving instruction for transmitting to the at least one vehicle a driving instruction specifying the transmitted at least one vehicle to be directed to the dispatch location. A transmission unit (117); and the plurality of vehicles is a driving request receiving unit (212) that receives the driving request signal; and a role that is set to itself based on the driving request signal A role coincidence determination unit (213) that determines whether or not the vehicle matches the specific role; an automatic driving toward the dispatch location and a role that is set in the dispatch location A state management unit (217) that manages its own state including a possible state; a state determination unit (214) that determines whether or not its state is the driveable state; and indicates its current position A position acquisition unit (254) for acquiring information; if it is determined that the role set in itself matches the specific role, and if it is determined that its state is the driveable state, Identification information and current position A driveable signal transmission unit (215) for transmitting the driveable signal indicating that the vehicle can be driven to the dispatch location to the management device; and a drive command for receiving the drive command A receiving unit (216); and an automatic driving control unit (218) for controlling automatic driving from the current position to the dispatch location according to the driving command.

  According to the vehicle allocation system of this embodiment, the management device (10) broadcasts a driving request signal including information indicating a specific role, and each vehicle (200, 200a) receives the driving request signal and If the role set in is consistent with the specific role indicated by the information included in the drive request signal, and the state of the player is in a driveable state, the identification information and the current position of the player are indicated. A driveable signal including information is transmitted to the management device, the management device transmits a drive command specifying at least one vehicle that has transmitted the driveable signal, and the vehicle is in accordance with the drive command, and the vehicle Controls automatic driving from to the place of dispatch. For this reason, the management apparatus does not need to manage all the information such as which vehicle is a vehicle for which a necessary role according to the situation is set, and where the current position of the vehicle is. Therefore, the facilities and labor required for managing the dispatch can be suppressed. In addition, since each vehicle transmits a driveable signal including information related to its current position to the management device, the management device uses the information included in the signal to position the vehicle far from the dispatch location. It is possible to prevent the vehicle from being dispatched.

  The present invention can also be realized in various forms other than the vehicle allocation system. For example, the present invention can be realized in the form of a vehicle, a management device, a vehicle allocation method, a computer program for realizing the method, a storage medium storing the computer program, and the like.

When such a menu is executed, the display device 181 may display a map, the position of each vehicle 200 on the map, and the role of each vehicle 200 as shown in FIG.

A3. Vehicle and road server configuration:
In the present embodiment, the vehicle 200 is an electric vehicle and obtains driving force by electricity stored in a storage battery (not shown). Instead of an electric vehicle, a gasoline vehicle in which fuel is burned by an internal combustion engine to obtain a driving force, a fuel cell vehicle in which power is generated by a fuel cell and used as a driving force, a hybrid vehicle in which these are combined to obtain a driving force, etc. There may be. As shown in FIG. 3, in addition to the lifesaving equipment 290, the vehicle 200 includes a main control ECU (Electronic Control Unit) 201, a wireless communication interface (I / F) unit 252, a position acquisition unit 254, and an image acquisition. A unit 256 and an operation control ECU 258 are provided. FIG. 3 shows a vehicle 200 equipped with a respirator as the lifesaving equipment 290, in other words, a vehicle 200 in which the role a is set.

  The main control ECU 201 includes a CPU 210, a RAM 230, and an EEPROM 240. The CPU 210 develops the control computer program stored in the EEPROM into the RAM 230 and executes it, so that the vehicle allocation request transmission unit 211, the driving request transmission unit 212, the role match determination unit 213, the state determination unit 214, the possible signal It functions as a transmission unit 215, a driving command reception unit 216, a state management unit 217, and an automatic operation control unit 218. Among these functional units, the automatic driving control unit 218 performs control for automatically moving the vehicle 200 toward the destination. Specifically, the travel route is identified from the relationship between the current position and the destination obtained by the position acquisition unit 254, and the driving control ECU 258 is controlled so that the vehicle 200 travels along the route. For example, the destination may be set by the driver, or when the driver is absent, information indicating the destination set by the management apparatus 100 is received and set via the road server rs. Also good. In addition, about the specific automatic driving | operation control method, you may use arbitrary well-known techniques. Among the above-described functional units 211 to 218, the specific processing contents of the functional units 211 to 217 other than the automatic driving control unit 218 will be described in the vehicle dispatching process described later.

The EERPOM 240 includes an ID storage unit 241, a role ID storage unit 242, a role state storage unit 243, and a dispatched state storage unit 244. The ID storage unit 241 stores in advance identification information (ID) that uniquely identifies the vehicle 200. As such identification information, for example, an automobile registration number (a number written on a license plate) may be used. The role ID storage unit 242 stores in advance identification information indicating the type of role. As such identification information, information of “a to e” representing the types of roles described above may be used. The role state storage unit 243 stores information indicating the role state. The role state means the state of the lifesaving equipment installed, and is set to one of the following three states (role states 1 to 3).
Role state 1: Life-saving equipment is available Role state 2: Life-saving equipment is usable, but consumables used in life-saving equipment are not replaced Role state 3: Life-saving equipment is out of order State In the initial state, role state 1 is set. Information indicating the role state stored in the role state storage unit 243 is set (changed) by the driver according to the state. Instead of the driver, the main control ECU 201 may automatically set itself.

The vehicle allocation state storage unit 244 stores information indicating the vehicle allocation state. The dispatch state means a use state of the vehicle as a whole, particularly a state related to dispatch, and is set to one of the following three states (allocation states 1 to 3).
Dispatching state 1: Normal state Dispatching state 2: In-run state Dispatched state 3: Steering complete state In the initial state, the dispatch state 1 is set. The main control ECU 201 automatically sets (changes) the information indicating the vehicle allocation state stored in the vehicle allocation state storage unit 244 by itself.

  The normal state of the dispatch state 1 indicates all states that are not the dispatch state 2 and 3. The dispatching state in the dispatching state 2 means a state in which the vehicle is being automatically driven toward the dispatching place in the vehicle dispatching process described later. In this case, in addition to a state where the vehicle is traveling toward the dispatch location, a state where the vehicle is temporarily stopped at a signal or the like in the middle of traveling toward the dispatch location is included. The driving completion state in the vehicle allocation state 3 means a state where the vehicle has arrived at the vehicle allocation place in the vehicle allocation process described later. Therefore, the above-mentioned normal state means all states that are not heading to the dispatch location or have not arrived at the dispatch location. For example, in addition to the state where the vehicle is traveling on the road, It includes a state where the vehicle is stopped and a state where the vehicle is parked in a parking lot.

  The wireless communication I / F unit 252 performs wireless communication with the road server rs. Further, it communicates with the management apparatus 100 via the wide area network 500. The wireless communication I / F unit 252 includes an interface group similar to the interface group included in the WAN I / F unit 160 included in the management apparatus 100 described above. The wireless communication I / F unit 252 includes various interface groups for performing wireless communication with the road server rs, for example, various wireless LAN and Z-Wave interface groups for wireless communication. In addition to these various interface groups, the wireless communication I / F unit 252 includes various functional units necessary for wireless communication such as a modulator, an amplifier, and an antenna.

  The main control ECU 201, the wireless communication I / F unit 252, the position acquisition unit 254, the image acquisition unit 256, and the operation control ECU 258 described above can communicate with each other via the in-vehicle network 260. In the present embodiment, a CAN (Control Area Network) standardized as ISO11898 is used as the in-vehicle network 260. Instead of CAN, a communication network of an arbitrary method applicable to the vehicle 200, such as LIN (Local Interconnect network) or FlexRay (registered trademark), may be used.

  The position acquisition unit 254 acquires information indicating the current position of the vehicle 200. In the present embodiment, the position acquisition unit 254 calculates the current position (latitude and longitude) based on a signal output from a global positioning system (GPS) satellite. Instead of GPS positioning, the current position may be acquired by receiving information (latitude and longitude) indicating the current position by wireless communication from a nearby road server rs. Alternatively, the position of each road server rs is stored in advance, a nearby road server rs is specified by wireless communication, and the current position of the vehicle 200 is estimated and acquired from the current position of the specified road server rs. Also good.

  The image acquisition unit 256 is mounted on the vehicle 200, captures a state around the vehicle 200, for example, a front or rear state, and acquires image data or image data thereof. Further, the image acquisition unit 256 captures the interior of the vehicle 200 and acquires the image data or image data. As such an image acquisition unit 256, a drive recorder device may be used.

  The driving control ECU 258 controls various functional units for realizing running and stopping in the vehicle 200 in accordance with instructions from the automatic driving control unit 218. Examples of the functional unit to be controlled include a drive motor, a brake mechanism, lighting, a blinker, and a navigation system. The operation control ECU 258 is electrically connected to various sensors (not shown), for example, a vehicle speed sensor, a wheel rotation number sensor, a remaining charge sensor, and the like, acquires various measurement values, and uses them for controlling various functional units.

  Note that the vehicle 200 in which the other roles b to e are set differs from the vehicle 200 shown in FIG. 3, that is, the vehicle 200 in which the role a is set only in the type of the lifesaving equipment 290 installed. Detailed description thereof will be omitted.

  As shown in FIG. 3, the road server rs includes a command receiving unit 11 and a wireless communication unit 12. The command receiving unit 11 is configured by a microcomputer including a CPU, a ROM, and a RAM (not shown). Specific processing contents of the command receiving unit 11 will be described in a vehicle dispatching process described later. The wireless communication unit 12 performs wireless communication with the vehicle 200. The wireless communication unit 12 communicates with the management apparatus 100 via the wide area network 500. Therefore, the wireless communication unit 12 includes an interface group similar to the interface group included in the wireless communication I / F unit 252 of the vehicle 200 described above. The wireless communication unit 12 includes an interface group similar to the interface group included in the WAN I / F unit 160 of the management apparatus 100 described above. In the present embodiment, the road server rs is embedded at predetermined intervals in the approximate center of each lane on the road. In FIG. 1, the position, size, and the like of the road server rs are schematically represented.

  As described above, in the management apparatus 100, when it is determined that an accident occurs at the position P0 and it is necessary to collect all the above five types of facilities at the position P0 as a response to the accident, each type of facility is installed. One mounted vehicle is driven to the position P0 one by one. By adopting such a configuration, there is an advantage to be described later as compared with a conventional configuration in which a vehicle equipped with all five types of facilities, for example, an emergency vehicle is prepared. In the conventional configuration, when an emergency vehicle is rushing to an accident site and a new accident occurs at another location, the emergency vehicle cannot rush to the newly generated accident site, or It takes a very long time to run. For this reason, there is a problem that many ambulance vehicles must be prepared in preparation for the occurrence of such a double accident. For example, a certain ventilator requires a ventilator, a blood oxygen saturation meter, and an end-tidal carbon dioxide partial pressure meter, and an aspirator is required at the same timing in an accident site different from the accident site. A conventional example is assumed in which only one emergency vehicle can be driven to these two accident sites. In this case, if an emergency vehicle rushes to one accident site, the life-saving equipment at the other accident site is not used at the other accident site, even though the life-saving equipment required at the other accident site is not used. Can not deliver. On the other hand, in the vehicle dispatch system 10 according to the present embodiment, the lifesaving equipment is distributed and mounted in advance on a plurality of vehicles, and the necessary kind of lifesaving equipment is executed by executing vehicle dispatch processing described later. Vehicles equipped with can be rushed to each accident site, and the necessary types of lifesaving equipment can be delivered to any accident site. Hereinafter, the vehicle allocation process will be described.

  The broadcast command transmission unit 115 and the road server rs correspond to subordinate concepts of the drive request transmission unit in the claims. The road server rs corresponds to a subordinate concept of the wireless device in the claims. The possible signal transmission unit 215 corresponds to a subordinate concept of the driveable signal transmission unit in the claims. The area Ar1 corresponds to a subordinate concept of the transmission target area in the claims.

A4. Vehicle dispatch processing:
In the sequence diagrams shown in FIGS. 4 and 5, the leftmost flowchart shows a processing procedure of a vehicle 200 that has caused an accident (hereinafter referred to as “accident vehicle”). Further, the central flowchart shows the processing procedure of the management apparatus 100, and the rightmost flowchart shows the processing procedure of the vehicle 200 different from the vehicle 200 that caused the accident.

  In the management device 100, the vehicle allocation request reception unit 111 waits for reception of a vehicle allocation request output from the accident vehicle after the management device 100 is powered on. When the vehicle allocation request receiving unit 111 receives the vehicle allocation request, the management device 100 executes a vehicle allocation process.

  In each vehicle 200, the driving request receiving unit 212 waits for reception of the driving request signal output from the management device 100. When the driving request receiving unit 212 receives the driving request signal, the vehicle dispatching process is executed in the vehicle 200. The driving request signal includes information indicating a specific role, and is a signal for requesting driving to a dispatch location. Here, in each vehicle 200, waiting for reception of the driving request signal by the driving request transmission unit 212 is executed even when the vehicle 200 is parked. For example, even when the vehicle 200 is parked (in other words, before the start button is pressed), the main control ECU 201 receives power supply from a storage battery (not shown) and waits for reception of a driving request signal. ing. When the driving request signal is received by the driving request transmission unit 212, the vehicle 200 is turned on with the reception as an opportunity (as an interrupt), and the vehicle 200 is ready to travel.

  As shown in FIG. 4, when an accident occurs, in the accident vehicle, the dispatch request transmission unit 211 detects the occurrence of the accident (step S105). In the present embodiment, such accident detection is realized by detecting that the airbag is operating. Instead of detecting the operation of the air bag or in addition to detecting the operation of the air bag, the detection of the stop of the vehicle 200 accompanied by a sudden decrease in the vehicle speed, or the operation of the dedicated button for notifying the driver by the driver is detected. For example, accident detection may be realized.

In the accident vehicle, the vehicle allocation request transmission unit 211 transmits a vehicle allocation request to the management device 100 (step S110). In the present embodiment, the dispatch request includes data indicating the following information.
・ Accident occurrence time ・ Current position ・ Number of passengers ・ Vehicle speed immediately before the accident ・ Ambient and passenger compartment images The current position is specified based on information acquired by the position acquisition unit 254. The number of occupants is specified by, for example, analyzing a detection result by a boarding sensor (not shown) arranged in each seat or an image in the passenger compartment. The vehicle speed immediately before the occurrence of the accident is specified by the detection result by the vehicle speed sensor. As the surrounding and vehicle interior images, images obtained by the image acquisition unit 256 before and after the occurrence of the accident are used. The vehicle allocation request transmission unit 211 wirelessly outputs data indicating the above-described information from the wireless communication I / F unit 252. The allocation request that is wirelessly output from the accident vehicle is transmitted to the management apparatus 100 via the wide area network 500.

  In the management device 100, the role specifying unit 112 specifies a specific role corresponding to the accident (hereinafter referred to as a “specific role”) from the five roles a to e based on the received dispatch request (step “step”). S205). The specific role may be specified based on, for example, the vehicle speed immediately before the occurrence of the accident or the surrounding and vehicle interior images. Specifically, based on the statistical data, the vehicle speed immediately before the occurrence of the accident and a specific role may be associated with each other and mapped, and the specific role may be specified by referring to the map. In this map, for example, if the vehicle speed immediately before the accident occurs is higher, the cardiopulmonary of the occupant is more likely to stop at the time of the accident, and statistical data is obtained that indicates that the frequency of using the automatic external defibrillator is higher May be set to specify the role c as one of the specific roles when the vehicle speed immediately before the occurrence of the accident is equal to or higher than a predetermined speed.

  In the management device 100, the dispatch location specifying unit 113 specifies the dispatch location based on the received dispatch request (step S210). In the present embodiment, the current position of the accident vehicle is specified as the dispatch location. That is, the dispatch location identifying unit 113 identifies the current position of the accident vehicle included in the dispatch request as the dispatch location.

  In the management device 100, the vehicle number identification unit 114 identifies the number of vehicles scheduled to be allocated at the allocation location based on the received allocation request (step S215). For example, based on information indicating the number of passengers included in the dispatch request, the number obtained by multiplying the number of passengers by the type of specific role may be specified as the number of vehicles scheduled to be dispatched. This is because there is a possibility that all passengers will be similarly damaged by the accident. In addition, it is good also as what arranges the number of vehicles of a specific role as the number of specific roles as a predetermined number of vehicles, ie, one vehicle for each specific role. In this case, in step S215, the number of vehicles scheduled to be dispatched can be specified by specifying the number of types of specific roles.

  In the management apparatus 100, the broadcast command transmission unit 115 commands the road server rs in an area of a predetermined size so as to broadcast the drive request, and each road server rs receives the command. The drive request is broadcasted (step S220). In the present embodiment, the rushing request is intended to specify a vehicle that should be a candidate for rushing to the dispatch location, that is, a vehicle for which a specific role is set. Therefore, the specific role specified in step S205 described above is specified in the drive-in request. Further, in the present embodiment, the area having a predetermined size means a circular area having a predetermined size centered on the vehicle allocation place, that is, the accident occurrence position. That is, a region Ar1 indicated by a one-dot chain line in FIG. In the present embodiment, the radius r1 of the region Ar1 is 10 km. In addition, it is good also considering arbitrary length as not only 10 km.

  As described above, in each vehicle 200, when the driving request transmission unit 212 receives the driving request broadcast from the road server rs, the vehicle allocation process is started. In each vehicle 200, the role matching determination unit 213 determines whether or not the role set in itself matches any of the specific roles specified in the driving request (step S305). When it is determined in step S305 that they do not match (step S305: NO), the vehicle dispatching process is completed in each vehicle 200. On the other hand, when it is determined in step S305 that they match (step S305: YES), the state determination unit 214 executes a driveable state determination process (step S310). The driveable state determination process is a state in which the vehicle 200 can automatically drive toward the placement location and can play a role set in itself at the placement location (hereinafter referred to as “driveable state”). This is a process of determining (identifying) whether or not there is.

  As illustrated in FIG. 6, when the driveable state determination process is started, the state determination unit 214 determines whether or not the role state is an available state (step S405). Specifically, information indicating the role state stored in the role state storage unit 243 is read, and it is determined whether or not the role state indicated by the information is the above-described “role state 1”. When it is determined that the role state is in an available state, that is, when it is determined that the set role state is “role state 1” (step S405: YES), the state determination unit 214 determines the dispatch state. Is determined to be in a normal state (step S410). Specifically, information indicating the vehicle allocation state stored in the vehicle allocation state storage unit 244 is read, and it is determined whether or not the vehicle allocation state indicated by the information is the above-mentioned “vehicle allocation state 1”.

  When it is determined that the dispatch state is the normal state, that is, when it is determined that the set dispatch state is “allocation state 1” (step S410: YES), the state determination unit 214 determines that the vehicle 200 is It is specified that the state can be driven (step S415). On the other hand, when it is determined in step S405 described above that the role state is not the usable state (step S405: NO), or when it is determined in step S410 that the dispatch state is not the normal state (step S405). (S410: NO), the state determination unit 214 specifies that the vehicle 200 is not in a driveable state (step S420). That is, it is specified that the vehicle can be driven only in the vehicle 200 in which the role state is usable and the dispatched state is normal. This is because, when the role state is not usable, the lifesaving equipment is out of order or the consumables are not replenished, and therefore the lifesaving equipment cannot be used even if the vehicle 200 rushes. In addition, when the dispatching state is not a normal state, the vehicle is heading to the dispatching place or has arrived at the dispatching place in response to another dispatching request, so that such a vehicle is directed to another accident site. If this happens, the lifesaving equipment will not be delivered to the accident site (the place where the vehicle is dispatched).

  As shown in FIG. 4, in each vehicle 200, when it is determined (determined) that the vehicle 200 is in a driveable state as a result of the driveable state determination process (step S310), the possible signal transmission unit 215 A drive enable signal is transmitted to the management apparatus 100 (step S315). This driveable signal is a response to the drive request signal and indicates that the transmission source vehicle 200 is in a driveable state. This driveable signal includes identification information of the transmission source vehicle 200, information indicating the current position of the vehicle 200, and information indicating the set role. On the other hand, in each vehicle 200, when it is determined (determined) that the vehicle 200 is not in the driveable state as a result of the driveable state determination process (step S310), the vehicle dispatching process ends in the vehicle 200.

  In the management apparatus 100, the driving vehicle determination unit 116, after completion of the above-described step S220 (broadcasting of driving request), outputs a possible driving signal equal to or more than the scheduled number of vehicles allocated in step S215 within a predetermined period. It is determined whether or not it has been received from each vehicle 200 (step S225). At this time, for each specific role, it is specified whether or not it is received for the scheduled number. Therefore, for example, when one vehicle allocation planned number is specified for each of the above five roles, in step S225, it is specified whether one or more signals for each role have been received. . In the area Ar1 shown in FIG. 1, there are two vehicles 200 of role a, three vehicles 200 of role c, two vehicles 200 of role d, and two vehicles 200 of role e. . However, there is no vehicle 200 of role b. Therefore, in this case, in step S225, it is determined that no driveable signal equal to or more than the number of vehicles to be dispatched is received from each vehicle 200 within a predetermined period.

  When it is specified that no more than the number of possible dispatch signals can be received from each vehicle 200 within a predetermined period (step S225: NO), the broadcast command transmission unit 115 is within the range in which the previous drive request was transmitted. In comparison, the transmission range is expanded, and a broadcast request broadcast request is transmitted to the road server rs, and each road server rs in a wider area broadcasts the drive request (step S230). As shown in FIG. 7, when step S230 is executed first, the area Ar2 in which the driving request is broadcast (more precisely, the area Ar2 including the road server rs that broadcasts the driving request) is , Larger than the region Ar1. Specifically, the area Ar2 has a circular shape and is common to the area Ar1, and the center position is common at the dispatch location, but the radius of the area increases from r1 to r2. In the present embodiment, the radius r2 is 15 km. The size is not limited to 15 km and may be any size larger than 10 km. As shown in FIG. 4, in order to return to step S225 after execution of step S230, step S230 is repeatedly executed until a driving enable signal equal to or more than the number of vehicles to be dispatched is received, and the range in which the driving request is broadcast gradually increases. Become. In the present embodiment, an area having a radius that is 1.5 times the radius of the area when the previous step S230 was executed is set as an area for broadcasting the driving request when the current step S230 is executed. Note that the magnification is not limited to 1.5, and an arbitrary magnification larger than 1.0 may be set. Also, the radius of such a region may increase exponentially. Further, the radius is not limited to 1.5 times the radius of the previous region, and the radius may be determined in advance each time. For example, a value that increases as the number of times may be determined in advance, such as 10 km for the first time, 15 km for the second time, and 20 km for the third time. As shown in FIG. 7, the vehicle 200 in which the role b is set exists in the difference area between the area Ar1 and the area Ar2. Therefore, in this case, in step S225, which is executed after step S230 is executed once, it is determined that more than the number of vehicles that can be dispatched are received from each vehicle 200 within a predetermined period.

  As described above, when it is determined that the possible driving signals for the number of vehicles to be allocated or more are received from each vehicle 200 within the predetermined period (step S225: YES), as shown in FIG. The attached vehicle determination unit 116 determines the number of vehicles 200 to be actually rushed to the dispatch location from among the vehicles 200 that have transmitted the enabling signal (step S235). In the present embodiment, the vehicle selection policy in step S235 is a policy of selecting the vehicle 200 closer to the dispatch location with higher priority. Specifically, the driving vehicle determination unit 116 determines the current position of the vehicle 200 indicated by the driving enable signal and the position of the dispatch location for each type of specific role among the vehicles 200 that have transmitted the enable driving signal. Is calculated, and a vehicle with a shorter distance is selected with higher priority. In the present embodiment, since one vehicle 200 is directed to each of all five roles a to e, the vehicle with the shortest calculated distance is selected for each role a to e.

  In the management device 100, the driving command transmission unit 117 transmits a driving command to the vehicle 200 determined in step S235 via the road server rs (step S240). Since the identification information and the current position of the vehicle 200 selected in step S235 can be specified based on the driving enable signal, in step S240, the driving command transmission unit 117 includes the identification information and the location information of the dispatch location. The broadcast command is transmitted to the road server rs close to the current position of the vehicle 200 so as to broadcast the driving command. The road server rs that has received the driving command broadcasts the driving command.

  In the vehicle 200 that has transmitted the drive enable signal in step S315 described above, the state management unit 217 determines whether or not a drive command is received within a predetermined period after step S315 is completed (step S320). If it is determined that the driving command is not received within the predetermined period (step S320: NO), the vehicle dispatching process ends in the vehicle 200. On the other hand, if it is determined that the driving instruction is received within the predetermined period (step S320: YES), the state management unit 217 changes the vehicle allocation state from the vehicle allocation state 1 (normal state) to the vehicle allocation state 2 (drive state). (Attached state) (step S325). The automatic driving control unit 218 controls the vehicle 200 to automatically drive toward the dispatch location specified by the driving instruction (step S330). The automatic driving control unit 218 determines arrival at the designated dispatch location (step S335). If it has not arrived (step S335: NO), the above-described step S330 is executed to continue the automatic driving control of the vehicle 200. When it is determined that the vehicle has arrived at the dispatch location (step S335: YES), the state management unit 217 changes the dispatch state from the dispatch state 2 (in-run state) to the dispatch state 3 (in-run state). A completion notification is transmitted to the management apparatus 100 (step S340), and the vehicle allocation process in the vehicle 200 ends.

  The management device 100 stands by until a dispatch completion notification is received from all the vehicles 200 to which the driving command is transmitted in step S240 (step S245). When the dispatch completion notification is received (step S245: YES), the management apparatus 100 The vehicle dispatch process in apparatus 100 ends.

  According to the vehicle dispatch system 10 of the first embodiment described above, the management device 100 broadcasts a driving request signal including information indicating a specific role via the wide area network 500 and the road server rs. , Upon receiving the drive request signal, when the role set in itself matches the specific role indicated by the information included in the drive request signal, and the own state is in a driveable state The control device transmits a drive enable signal including the identification information of the vehicle and information indicating its current position to the management device. The management device transmits a drive command specifying the vehicle 200 that has transmitted the drive enable signal. The automatic operation from the current position to the dispatch location is controlled according to the driving instruction. For this reason, the management apparatus 100 needs to manage all the information such as which vehicle is the vehicle 200 in which a necessary role according to the situation is set, and where the current position of the vehicle is. No. Therefore, the facilities and labor required for managing the dispatch can be suppressed. In addition, each vehicle 200 transmits a driveable signal including information related to its current position to the management device 100, so that the management device uses the information included in the signal so that the vehicle 200 Distributing a vehicle at a far position can be suppressed.

  In addition, each vehicle 200 is equipped with different types of lifesaving equipment and the role of providing such lifesaving equipment is set. Therefore, vehicles equipped with necessary types of lifesaving equipment are rushed to each accident site. This makes it possible to deliver the necessary types of lifesaving equipment to any accident site, even if an accident occurs repeatedly.

  In addition, since the management device 100 broadcasts the driving request via the road server rs in a circular area having a predetermined size centered on the vehicle placement location, the management device 100 is estimated to take a long time to run to the vehicle delivery location ( Hereinafter, the vehicle 200 having a relatively short driving time) can be rushed to the place of placement.

  In addition, the management device 100 expands the transmission range compared to the range in which the last driving request is transmitted when the signals that can be driven more than the specified number of dispatched vehicles are not received from each vehicle 200 within a predetermined period. Thus, the broadcast request broadcast request is transmitted to the road server rs, and the drive request is broadcast from each road server rs in a wider area. For this reason, while giving priority to the vehicle 200 closer to the dispatch location, it is possible to rush the vehicles 200 for the planned dispatch number to the dispatch location.

  In addition, since the management device 100 automatically identifies the specific role and the number of vehicles 200 to be dispatched based on the dispatch request, it is possible to identify these pieces of information without going through the operator 400 and to save the labor of the operator 400. .

  In addition, in the vehicle 200 that has received the driving request, the driving enable signal is transmitted only when the role state is the usable state and the dispatched state is the normal state. A vehicle that is equipped with equipment and does not cause a problem of being unable to respond to other driving requests even if it is rushed to the placement location can be rushed to the dispatch location.

B. Second embodiment:
B1. Device configuration:
The vehicle allocation system of the second embodiment includes a management device 100a shown in FIG. 8 instead of the management device 100, and a plurality of vehicles 200a shown in FIG. 9 instead of the plurality of vehicles 200. And the vehicle allocation system 10 of the first embodiment. Since the other structure in the vehicle allocation system of 2nd Embodiment is the same as the vehicle allocation system 10 of 1st Embodiment, the same code | symbol is attached | subjected to the same component and the detailed description is abbreviate | omitted.

  The management apparatus 100a of the second embodiment shown in FIG. 8 is different from the management apparatus 100 of the first embodiment in that the hard disk 120 includes a condition storage unit 121. Since other configurations in the management device 100a of the second embodiment are the same as those of the management device 100 of the first embodiment, the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

  The condition storage unit 121 stores information indicating a condition indicating that the driving time is equal to or shorter than a predetermined time (hereinafter referred to as “drive time related condition”). In the present embodiment, the driving-related time condition means a threshold Tth of driving time required from the current location to the dispatch location. In the initial state, a predetermined value is stored as an initial value as the threshold value Tth. The threshold value Tth can be updated in a vehicle dispatching process described later. However, when the vehicle dispatch process is completed, the initial value is restored. In the present embodiment, 5 minutes is set as the initial value of the threshold value Tth. Note that the time is not limited to 5 minutes, and an arbitrary time allowed as the driving time may be set.

  The vehicle 200a of the second embodiment shown in FIG. 9 is different from the vehicle 200 of the first embodiment shown in FIG. 3 in that the CPU 210 also functions as the driving time specifying unit 219. Since other configurations in the vehicle 200a of the second embodiment are the same as those of the vehicle 200 of the first embodiment, the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

  The driving time specifying unit 219 calculates the driving time. Such calculation may be performed by a calculation method similar to that of a navigation system (not shown). For example, using the information on the current position specified by the position acquisition unit 254, the position information on the dispatch location notified from the management device 100a as will be described later, and the information on the vehicle speed obtained from a vehicle speed sensor (not shown), The attached time may be calculated. Alternatively, the driving time specifying unit 219 passes the information on the current position and the vehicle location to a navigation system (not shown) mounted on the vehicle 200a, and acquires the driving time calculated by the navigation system using the information and the vehicle speed information. By this, the driving time may be specified. In addition, the server device arranged at a place different from the vehicle 200a is passed the information on the current position and the dispatch location via the wide area network 500, and the operation time calculated by the server device using the information and the vehicle speed information. May be specified via the wide area network 500 to specify the driving time.

B2. Vehicle dispatch processing:
The vehicle dispatching process of the second embodiment shown in FIG. 10 is performed in the point that step S220a is executed instead of step S220, the step S230a is executed instead of step S230, and the detailed procedure of step S310. 4 is different from the vehicle allocation process of the first embodiment shown in FIG. Since other procedures in the vehicle allocation process of the second embodiment are the same as the vehicle allocation process of the first embodiment, the same procedures are denoted by the same reference numerals, and detailed description thereof is omitted. Note that the procedure shown in FIG. 5 is similarly executed in the second embodiment.

  As shown in FIG. 10, in the management apparatus 100a, the broadcast command transmission unit 115 commands all the road servers rs to broadcast the driving request, and each road server rs receives the command. The drive request is broadcast (step S220a). The driving request transmitted at this time is different from the driving request transmitted in step S220 of the first embodiment in that it includes a threshold Tth of driving time and information indicating a dispatch location.

  In each vehicle 200a, when step S305 is executed and it is determined that they match (step S305: YES), the state determination unit 214 executes a driveable state determination process (step S310).

  As shown in FIG. 11, the driveable state process of the second embodiment is different from the driveable state process of the first embodiment shown in FIG. 6 in that steps S412 and S414 are added and executed. Since the other procedures in the driveable state process of the second embodiment are the same as the driveable state process of the first embodiment, the same steps are denoted by the same reference numerals and detailed description thereof is omitted. To do.

  After it is determined that the role state is the usable state (step S405: YES) and the dispatch state is determined to be the normal state (step S410: YES), the driving time specifying unit 219 receives the received driving The driving time is specified using the information indicating the dispatch location included in the attachment request, the current position specified by the position acquisition unit 254, and the like (step S412).

  The state determination unit 214 determines whether or not the driving time specified in step S412 is equal to or less than the threshold value Tth specified in the driving request (step S414). When it is determined that the driving time is equal to or less than the threshold value Tth (step S414: YES), the above-described step S415 is executed, and the state determination unit 214 specifies that the vehicle 200 is in a driving enabled state. On the other hand, when it is determined that the driving time is not less than or equal to the threshold value Tth, that is, the driving time is longer than the threshold value Tth (step S414: NO), the above-described step S420 is executed, and the state determination unit 214 The vehicle 200a is identified as not being ready for driving. In general, since a relatively long time is specified as the driving time in the vehicle 200a located at a location far from the dispatch location, there is a high possibility that it is determined that the driving is not possible. On the other hand, since a relatively short time is specified as the driving time for the vehicle 200a located near the place where the vehicle is dispatched, there is a high possibility that it is determined that the vehicle can be driven.

  As shown in FIG. 10, after the above-described driveable state process (step S310) is completed, when it is determined that the state is ready for drive, the above-described step S315 is executed, and the driveable signal is transmitted to the management device 100a. Sent to.

  In the management device 100a, the driving vehicle determination unit 116 executes the above-described step S225 after the completion of the above-described step S220a. And when it determines with not receiving the signal which can be driven more than the number of vehicles dispatched from each vehicle 200 within a predetermined period (step S225: NO), the broadcast command transmission part 115 is in the driving request transmitted last time. The driving request including the threshold Tth for which the time longer than the specified threshold Tth is set is transmitted to all the road servers rs, and each road server rs broadcasts the driving request (step S230a). In the present embodiment, a driving request including a threshold value Tth that is set for one minute longer than the threshold value Tth specified in the previously transmitted driving request is broadcast as the current driving request. In addition, you may set not only 1 minute but the time longer than last time by arbitrary time as threshold value Tth. Further, for example, a length such as 1.5 times the previous threshold value Tth may be set as the current threshold value Tth.

  By transmitting a driving request in which a longer threshold value Tth is set, there is a high possibility that the number of vehicles 200a that are determined to be in a driving enabled state is increased from the previous time. In addition, it is highly possible that the vehicle 200a that is newly determined to be capable of being driven is present at a position relatively close to the dispatch location. After the completion of step S230a, the process returns to step S225. Therefore, step S230a is repeatedly executed until the number of possible dispatch signals equal to or more than the number of vehicles to be dispatched is received, and the threshold value Tth gradually increases. Each time step S230a described above is executed, the threshold value Tth stored in the condition storage unit 121 is overwritten and updated.

  The vehicle allocation system of the second embodiment described above has the same effect as the vehicle allocation system 10 of the first embodiment. In addition, each vehicle 200a transmits a drive enable signal when the calculated drive time is equal to or less than the threshold value Tth, and does not transmit a drive enable signal when the calculated drive time is equal to or less than the threshold value Tth. The vehicle 200a that is actually rushed to the dispatch location can be selected from the vehicles 200a with a relatively short attachment time.

  In addition, the management device 100a, when not receiving a signal capable of driving more than the specified number of vehicles to be dispatched from each vehicle 200 within a predetermined period, a driving request in which a longer time is set as the threshold Tth, Broadcasting is performed via the road server rs. For this reason, it is possible to rush the vehicles 200 for the number of vehicles to be dispatched to the dispatch location while giving priority to the vehicles 200 that are likely to reach the dispatch location in a short time.

C. Variations:
C1. Modification 1:
In the above-described embodiment, the plurality of types of roles a to e in which the vehicles 200 and 200a are set are provided by providing different types of life saving equipment, but the present invention is limited to this. Not. For example, instead of the lifesaving equipment, a role of providing equipment used for any purpose such as leisure or lodging may be provided. In addition, instead of the role of providing and installing such equipment, the vehicle itself may have a certain characteristic, and the role of providing such a characteristic may be used. For example, since a certain vehicle has a feature that a large number of people can get on it, the vehicle may have a role of “to get on a large number of people”. In addition, since the other vehicle has a feature that a person on a wheelchair can get on as it is, it may have a role of “to get on a person on a wheelchair as it is”. In addition, since the other vehicle has a feature that AC 100V can be supplied to the outside, it may have a role of “supplying AC 100V to the outside”. That is, in general, a plurality of vehicles in which a plurality of types of roles are set in a distributed manner and can be automatically driven may be used in the vehicle dispatch system of the present invention.

C2. Modification 2:
In each embodiment, the specific role and the number of vehicles to be allocated are both specified by the management devices 100 and 100a, but at least one of these is specified by the operator 400 instead of the management devices 100 and 100a. May be. That is, based on the information included in the dispatch request received from the accident vehicle, the operator 400 may identify at least one of the specific role and the predetermined number of dispatches. In this configuration, the management devices 100 and 100a may cause the display device 181 to display various types of information included in the dispatch request. For example, other information excluding surrounding and vehicle interior images may be displayed as character strings, and surrounding and vehicle interior images may be displayed as images as they are. By doing in this way, the operator 400 can specify the specific role and the number of vehicles to be allocated with high accuracy based on the information displayed on the display device 181. In this configuration, the operator 400 may specify the specific role and the number of vehicles to be dispatched by contacting an occupant of the accident vehicle.

C3. Modification 3:
In each embodiment, the specific role is specified according to the scale and type of the accident based on the information included in the dispatch request, but the present invention is not limited to this. For example, all five roles a to e may always be specified as specific roles. Moreover, although the role set to each vehicle 200,200a was one type, respectively, a plurality of types of roles may be set to at least one vehicle 200,200a. In other words, a plurality of types of lifesaving equipment may be redundantly mounted on at least one vehicle 200, 200a. That is, in general, at least one type of roles among a plurality of types of roles may be set, and a plurality of vehicles capable of automatic driving may be used in the vehicle allocation system of the present invention.

C4. Modification 4:
In the second embodiment, the driving time is used in the determination of whether or not the vehicle is ready for driving (driveable state determination processing). However, instead of the driving time, the distance from the current location to the dispatch location is used. (Total path length) may be used. In this case, when the road is equal to or smaller than the threshold value, it is specified that the vehicle can be driven, and when the road is larger than the threshold value, the vehicle is not determined to be driven.

C5. Modification 5:
In the first embodiment, the road server rs to which the broadcast command is transmitted is the road server rs that exists in a circular area of a predetermined size, but all the road servers rs are used as the broadcast command transmission destination. Also good. In this configuration, information indicating the dispatch location is included in the broadcast command, and in each road server rs, the output when the driving request is broadcasted as the distance between the installation location and the dispatch location is shorter. The output when broadcasting the driving request may be reduced as the distance increases. According to such a configuration, the road server rs farther away from the dispatch location has a smaller output when broadcasting the driving request, and therefore the possibility that the vehicle 200 receives the driving request is low. For this reason, similar to the first embodiment, the vehicle 200 estimated to have a relatively short driving time can be given priority and rushed to the location.

C6. Modification 6:
In the second embodiment, the determination as to whether or not the driving time is equal to or less than the threshold value Tth is performed in the driving enabled state determination process, but may be performed separately from the driving enabled state determination process. Good. For example, the driveable state determination process (step S310) executes the same process as in the first embodiment, and separately, at any timing between step S305 and step S315, that is, before step S310. Alternatively, it may be determined later whether or not the driving time is equal to or less than the threshold value Tth. In this case, if the driving time is not equal to or less than the threshold value Tth, the vehicle dispatching process in the vehicle 200a is completed. If the driving time is equal to or less than the threshold value Tth, step S310 is continued or step S315 is continued. May be.

C7. Other variations:
In addition to the first to sixth modifications described above, the following modifications are also applicable. In each embodiment, when the vehicles 200 and 200a have arrived at the dispatch location, the vehicle allocation completion notification is transmitted to the management devices 100 and 100a. However, the transmission of the vehicle allocation completion notification may be omitted. In the first embodiment, the area (areas Ar1, Ar2, etc.) to which the road server rs that is the transmission destination of the broadcast command belongs is a vehicle allocation place, that is, an area centered on the position of the accident vehicle. May be a region including at any position. Moreover, the area | region which does not include a dispatch place may be sufficient. In addition, in the first embodiment, the shape of the area to which the road server rs that is the transmission destination of the broadcast command belongs is a circle, but the shape is not limited to a circle and may be an arbitrary shape. Further, in the first embodiment, the range for broadcasting the driving request has been expanded until the signals for driving that are equal to or more than the number of vehicles to be dispatched are received, but the range to be expanded or the driving request is broadcast in this way. An upper limit may be set for the number of times. When the upper limit is reached, the number of vehicles 200 as close as possible to the number of vehicles to be allocated for each specific role may be directed to the vehicle allocation location. Similarly, in the second embodiment, an upper limit value may be set for the upper limit value of the threshold value Tth or the number of times that the drive request is broadcast. Further, in each vehicle 200, step S305 and step S310 may be executed in a reversed order. Further, step S305 and step S310 may be executed simultaneously.

  In each embodiment, a part of the configuration realized by hardware may be replaced by software, and conversely, a part of the configuration realized by software may be replaced by hardware. In addition, when part or all of the functions of the present invention are realized by software, the software (computer program) can be provided in a form stored in a computer-readable recording medium. “Computer-readable recording medium” is not limited to a portable recording medium such as a flexible disk or a CD-ROM, but is fixed to an internal storage device in a computer such as various types of RAM and ROM, or a computer such as a hard disk. It also includes an external storage device. That is, the “computer-readable recording medium” has a broad meaning including an arbitrary recording medium capable of fixing a data packet instead of temporarily.

  The present invention is not limited to the above-described embodiments and modifications, and can be realized with various configurations without departing from the spirit thereof. For example, the technical features in the embodiments and the modifications corresponding to the technical features in each embodiment described in the summary section of the invention are to solve some or all of the above-described problems, or In order to achieve part or all of the effects, replacement or combination can be performed as appropriate. Further, if the technical feature is not described as essential in the present specification, it can be deleted as appropriate.
