The user may select the delivery vehicle among a plurality of vehicles using the mobile device.From JP 2016 / 091 411 A, an automatic vehicle allocation system is known which is capable of allocating a vehicle to an arbitrary location according to a situation. For this purpose, a central device acquires information indicating a current location of a user and information indicating a current location and a use situation of a vehicle, and determines an available vehicle to be assigned to the user and an entry location based on these information elements. The central device sets a user route from the user's current location to the boarding location and a vehicle route from the current location of the vehicle to be assigned to the boarding location. The central device transmits route information indicating the user route to a communication terminal held by the user and route information indicating the vehicle route to the vehicle to be assigned. In this case, the communication terminal held by the user is authenticated in the direction of the central device in order to check whether communication terminal is permitted for use of the vehicle assignment system. When the vehicle receives the route information indicating the vehicle route from the central device, it travels the vehicle to the boarding location by automatically traveling along the route indicated by the route information.US 2016 / 0 247 394 A1 discloses a method and a device for vehicle classification based on a degree of automation.SummaryIncidentally, in some cases, the user selects an autonomous driving vehicle as the delivery vehicle.

Hereinafter, a vehicle 2 representative of these vehicles will be described when describing the configuration common to the vehicles.Hardware Configuration of Vehicle Delivery SystemFIG. 2 is a diagram showing an example of a hardware configuration of the user device 10. As shown in FIG. 2, the user device 10 includes a processor 101, a memory (memory) 102, a storage (storage) 103, a communication interface 104, and a user interface 105 (an example of a display unit), and is a general-purpose computer.The processor 101 is an arithmetic and logic unit such as a central processing unit (CPU). The memory 102 is a storage medium such as a read only memory (ROM) or a read-write memory (RAM). The storage device 103 is a storage medium such as a hard disk drive (HDD). The communication interface 104 is a communication device that realizes data communication. The user interface 105 is an output device such as a liquid crystal or a speaker, and an input device such as a touch panel (touch panel) or a microphone. The processor 101 fundamentally manages the memory 102, the storage 103, the communication interface 104, and the user interface 105, and realizes functions of the user device which will be described below. The user device 10 may include a global positioning system (GPS) receiver.Similarly to the user device 10, the server 30 includes a processor 301, a memory (memory) 302, a storage device (storage) 303 (an example of a storage unit), a communication interface 304, and a user interface 305. The processor 301 fundamentally manages the memory 302, the storage 303, the communication interface 304, and the user interface 305, and realizes functions of the server 30 described below.The vehicle 2 includes an electronic control unit (ECU). Similarly to the user device 10, the ECU includes a processor 201, a memory (memory) 202, a storage (storage) 203, a communication interface 204, and a user interface 205. The processor 201 fundamentally manages the memory 202, the storage 203, the communication interface 204, and the user interface 205, and realizes functions of the vehicle 2 described below. The vehicle 2 may include a GPS receiver. When the vehicle 2 is the autonomous driving vehicle, the vehicle may have the basic configuration of the autonomous driving vehicle such as a sensor (not shown).Functions of Vehicle Delivery SystemFIG. 3 is a block diagram showing an example of the functions of the vehicle delivery system 1. As shown in FIG. 3, the user device 10 includes a vehicle delivery position transmission unit 11, a candidate reception unit 13, a display control unit 14, an accepting unit 15, and a delivery vehicle request unit 16.The vehicle delivery position transmission unit 11 transmits a vehicle delivery position to the server 30. the vehicle delivery position transmission unit 11 is mainly realized by the processor 101 operating the communication interface 104 with reference to the memory 102 and the storage 103. The vehicle delivery position is a position at which a delivery vehicle is to be delivered, and is a position at which the user gets on the vehicle. For example, the vehicle delivery position is specified by a user operation. For example, a position where the user performs an operation for typing his fingers on a map displayed on the user interface 105 of the user device 10 becomes the vehicle delivery position. The vehicle delivery position may be determined based on a position of the GPS receiver included in the user device 10.The candidate receiving unit 13 receives information regarding the autonomous driving function of at least one candidate vehicle together with the at least one candidate vehicle from the server 30. the candidate receiving unit 13 is realized mainly by the processor 101 operating the communication interface 104 with reference to the memory 102 and the storage 103. The candidate vehicles are vehicles as candidates of the delivery vehicle. The information regarding the autonomous driving function is information regarding the capability or reliability of autonomous driving. A specific example of the information regarding the autonomous driving function is the presence or absence of the autonomous driving function, dimension information, and an autonomous driving history. The details of the information regarding the autonomous driving function will be described below. The "candidate receiving unit receives information regarding the autonomous driving function from at least one candidate vehicle together with the at least one candidate vehicle" means that the candidate receiving unit receives the information so as to determine which candidate vehicle is the information regarding the autonomous driving function, such as information of the first candidate vehicle and information of the second candidate vehicle. For example, the candidate receiving unit 13 receives a vehicle identification number of the candidate vehicle together with the information regarding the autonomous driving function.The display control unit 14 displays the information regarding the autonomous driving function of at least one candidate vehicle received by the candidate receiving unit 13 together with at least one candidate vehicle at the user interface 105. The display control unit 14 is mainly realized by the processor 101 operating the user interface 105 with reference to the memory 102 and the storage 103. The "display control unit displays the information regarding the autonomous driving function of at least one candidate vehicle received by the candidate receiving unit at the user interface 105" means that the display control unit displays the information regarding the autonomous driving function such that the user can visually recognize whose candidate vehicle is the information regarding the autonomous driving function. For example, the display control unit 14 displays icons of the candidate vehicle together with the map at the user interface 105, and displays the information item regarding the autonomous driving function together with the icon. For example, the display control unit 14 may display a balloon (speaking) at the icon of the candidate vehicle, and may display the information regarding the autonomous driving function. Alternatively, the user performs an operation for selecting the icon of the candidate vehicle (for example, a tap operation), and thereby the display control unit 14 can display the information regarding the autonomous driving function. Alternatively, the display control unit 14 may display the vehicle identification number of the candidate vehicle together with the information regarding the autonomous driving function.The accepting unit 15 accepts a user operation for selecting the delivery vehicle from at least one candidate vehicle. The accepting unit 15 is realized mainly by the processor 101 operating the user interface 105 with reference to the memory 102 and the storage 103. The user operation for selecting the delivery vehicle is, for example, an operation for tapping the candidate vehicle displayed at the user interface 105.The delivery vehicle request unit 16 transmits the information identifying the delivery vehicle selected based on the user operation to the server. The delivery vehicle request unit 16 is realized mainly by the process 101 operating the communication interface 104 with reference to the storage 102 and the storage 103. The information for identifying the delivery vehicle is information capable of specifying the delivery vehicle, and is, for example, the vehicle identification number.As described above, in the user device 10, the candidate vehicle is displayed together with the information regarding the autonomous driving function, and the delivery vehicle is determined based on the user operation.The server 30 includes a position acquisition unit 31, a vehicle delivery position acquisition unit 32, a candidate vehicle determination unit 34, a candidate transmission unit 35, a delivery vehicle reception unit 36, and a vehicle delivery processing unit 37.The storage 303 of the server 30 stores the information items of the autonomous driving functions of the plurality of registered vehicles. The registered vehicles are vehicles that have been registered in advance in the vehicle delivery system 1. The vehicle identification numbers are assigned to the registered vehicles. The vehicle identification numbers are the IDs for identifying the vehicles. The vehicle identification number may be a number assigned together with a vehicle-specific number (a vehicle number reproduced on a license plate, a vehicle body number engraved on a vehicle body, or a physical address assigned to a communication device) by the vehicle delivery system 1, or may be the vehicle-specific number.FIG. 4 is an example of data held at the server 30. As shown in FIG. 4, the storage 303 stores a current vehicle position, a current driving state, a current seating state of a driver's seat, together with the vehicle identification number. The vehicle position is a position on the map, and is, for example, a longitude and a latitude. The driving state is one of autonomous driving and manual driving. These pieces of information are obtained from the vehicle 2 or a communication infrastructure on a road.The storage 303 stores the information regarding the autonomous driving function together with the vehicle identification number. As an example of the information regarding the autonomous driving function, the presence or absence of the autonomous driving function, version information of the autonomous driving function, an intervention rate, the continuity of the autonomous driving, a maximum value of a continuous distance of the autonomous driving (or a maximum value of a continuous time), an average value of the continuous distance of the autonomous driving (or an average value of the continuous time), and a cumulative value of the continuous distance of the autonomous driving (or a cumulative value of the continuous time).The presence or absence of the autonomous driving function indicates whether or not the autonomous driving can be performed, and indicates information for determining whether or not the vehicle can perform the autonomous driving. The version information of the autonomous driving function is version information of the autonomous driving system. An intervention is an intervention by the driver during autonomous driving. The engagement rate is the number of times an engagement occurs per unit distance. For example, a case where the intervention rate is "1" (number of times per kilometer) means that an intervention per kilometer occurs. The continuity of the autonomous driving is an index for evaluating a length from the start to the end of the autonomous driving. For example, the continuity is a ratio of the autonomous driving continuous distance to a total traveling distance in the autonomous driving. For example, when the autonomous driving persistence distance is 50 km out of 100 km, which is the total travel distance in the autonomous driving, the continuity is 0.5.In FIG. 4, for example, the vehicle identification number "2A" is associated with the vehicle position "longitude: XX, latitude: XX", a driving state "autonomous driving", a seating state of the driver's seat "presence", an autonomous driving function "presence", version information "1.0", an intervention rate "1", a continuity "0.5", a maximum value of a continuous distance "50 km", an average value of a continuous distance "20 km", and a cumulative value of a continuous distance "600 km".

The destination is an intended point of the user. For example, the destination is specified by a user operation. For example, a position to which the user taps on the map displayed on the user interface 105 of the user device 10 with his finger becomes the target. The destination may be entered using a keyboard. Other functions of the user equipment 10 are the same as those in the first embodiment.The server 30 further includes a target receiving unit 33. the target receiving unit 33 receives the target from the user device 10. the target receiving unit 33 is mainly realized by the processor 301 operating the communication interface 304 with reference to the memory 302 and the storage 303.The candidate transmission unit 35 of the server 30 calculates one or a plurality of estimation routes and an estimation required time (estimated required time) from the vehicle delivery position to the destination based on the vehicle delivery position, the destination, and the map information. For example, the map information is stored in the storage 303, and information capable of determining whether to perform the autonomous driving is embedded. For example, the information capable of determining whether or not to perform the autonomous driving is information (position information of a (driving) lane boundary line, position information of a post, traffic rules, or the like) necessary in the autonomous driving. On the estimation route, a portion in which the information required in the autonomous driving is included is an autonomous driving enabling portion.Autonomous driver enabling section (autonomous driving enabled section), and a section where the information required in autonomous driving is not included is an autonomous driving non-enabling section (autonomous driving disabled section). Alternatively, on the estimation route, the reliability equal to or greater than a predetermined value may not be ensured in a portion where the data is insufficient, this portion may be determined as the autonomous driving non-enabling portion. Alternatively, information indicating whether or not to perform the autonomous driving may be assigned to each section in advance. The candidate transmission unit 35 determines the autonomous driving enabling section or a section in which it is necessary to perform the manual driving for each estimation route, and generates data obtained by associating the information with the candidate vehicle.

The delivery vehicle displays the authentication information on a side surface of the vehicle. For example, the displayed authentication information is a computer readable code. The user device 10 reads the code displayed on the side surface of the delivery vehicle using an image sensor such as a camera or a dedicated reader. Accordingly, the user device 10 may acquire the authentication information directly from the delivery vehicle.An example of the method of acquiring the authentication information from the user device 10 at the delivery vehicle is disclosed.

The same contents of the fourth embodiment as those in the third embodiment are not repeated.FIG. 13 is a block diagram showing an example of an authentication function of the vehicle delivery system 1 according to the fourth embodiment. As shown in FIG. 13, the server 30 further includes a determination unit 38.When the vehicle delivery process of FIG. 7 or 10 is completed, the determination unit 38 of the server 30 determines whether or not the delivery vehicle is a manned vehicle at the time of delivery of the vehicle. The determination unit 38 is mainly realized by the processor 301 operated with reference to the memory 302 and the storage 303. For example, the determination unit 38 reads the seating state of the driver of the delivery vehicle and determines whether or not the delivery vehicle is the manned vehicle with reference to the storage 303. That is, whether or not the delivery vehicle is the manned vehicle means whether or not the driver is seated on the driver's seat.When the determination unit 38 determines that the delivery vehicle is the manned vehicle at the time of delivery of the vehicle, the generation unit 39 of the server 30 does not generate the authentication information. The generation unit 39 generates information for confirming that the combination thereof is correct by conversation between the driver and the user instead of the authentication information, and presents the generated information to both the driver and the user. Information of the delivery vehicle and information of the user are used as an example of such information. For example, the vehicle identification number of the delivery vehicle, the vehicle type, and the information of the driver are used as the information of the delivery vehicle. For example, a user ID, user device specific information (telephone number, fixed address, or the like) is used as the information of the user.The authentication information transmission unit 40 transmits the information of the delivery vehicle to the user device 10, and transmits the information of the user to the delivery vehicle.
