[Figure 3] FIG. 2 is a block diagram illustrating an example of the configuration of a vehicle and a server that constitute the system according to the embodiment.

[Figure 5] 10 is a flowchart showing a process of outputting a parking distance difference in a server according to the second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] If a parking lot recommended by the vehicle's navigation system becomes full before the user arrives, the user must search for another parking lot. If the navigation system does not provide information about available parking lots, the user must search for an available parking lot on their own. In order to find a parking space, vehicles may drive around the area. This can cause traffic congestion. It can also lead to a decrease in user satisfaction in tourist areas. However, even if traffic congestion occurs due to such reasons, it can be difficult to distinguish it from traffic congestion caused by other reasons. This can make it difficult to take appropriate measures to alleviate the congestion.

[0010] In order to solve such problems, an information processing device that is one aspect of the present disclosure includes a control unit configured to perform the following operations: acquire a parking location for the vehicle; acquire a first location that is the location where the vehicle first entered within a first predetermined distance from the parking location; acquire a first distance that the vehicle actually traveled from the first location to the parking location; acquire a second distance along a predetermined route from the first location to the parking location; and output an index corresponding to the behavior of the vehicle before parking based on a comparison between the first distance and the second distance.

[0011] The vehicle's parking location can be obtained, for example, by receiving from the vehicle a detection value from a position information sensor mounted on the vehicle. Examples of the vehicle's parking location include the location where the vehicle's power switch is operated to shut down the vehicle's system, the location where the ignition switch is switched from ON to OFF, and the location where the doors are locked from outside the vehicle. The first predetermined distance is the distance that results in a difference in travel distance between when the vehicle drives around looking for a parking space before parking at the parking location and when the vehicle is parked directly at the parking location. The first predetermined distance is, for example, 1 km. The first point is the point where the vehicle first enters within the first predetermined distance from the parking location. Therefore, even if the vehicle subsequently moves outside the first predetermined distance from the parking location and then enters within the first predetermined distance again during one trip, the first point remains the same. The first distance is the distance the vehicle actually traveled from the first point to the parking location. This first distance can be obtained, for example, based on the vehicle's travel history.

[0012] The control unit also acquires a second distance for the predetermined route. The predetermined route is, for example, the route of the vehicle when the vehicle travels from the beginning with the parking point as the destination point. The predetermined route may be, for example, the shortest route from the first point to the parking point. The shortest route is, for example, the route that the vehicle can travel in the shortest distance on roads that are passable by the vehicle. As another example, the predetermined route may be a general route from the first point to the parking point. For example, the predetermined route may be a route that is selected with priority given to roads that are relatively easy for vehicles to travel, such as main roads. As another example, the predetermined route may be a route that is assumed to be a straight line connecting the first point to the parking point. In this case, the second distance is equal to the first predetermined distance.

[0013] Here, the difference between the first distance and the second distance becomes larger as the vehicle drives around searching for a parking space. In other words, the larger the difference between the first distance and the second distance, the longer the distance the vehicle traveled searching for a parking space. Therefore, the difference between the first distance and the second distance can be treated as an index corresponding to the behavior of the vehicle before parking. By outputting this index, for example, the method of guiding the vehicle to the parking space can be revised. As another example, the ratio between the first distance and the second distance can be used as an index corresponding to the behavior of the vehicle before parking.

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configurations of the following embodiments are examples, and the present invention is not limited to the configurations of the embodiments. Furthermore, the following embodiments can be combined as much as possible.

[0015] First Embodiment FIG. 1 is a diagram showing an outline of a system 1 according to an embodiment. In the example of FIG. 1, the system 1 includes a vehicle 10 and a server 30. Although one vehicle 10 is illustrated in FIG. 1 as an example, the present invention is not limited to this and there may be a plurality of vehicles 10. The vehicle 10 and the server 30 are connected to each other by a network N1. Note that the network N1 may be, for example, the Internet. The network N1 may be a global public communication network such as a WAN (Wide Area Network) or other communication network. The network N1 may also include a telephone communication network such as a mobile phone network, or a wireless communication network such as Wi-Fi (registered trademark).

[0016] FIG. 1 shows the travel path of vehicle 10 until it is parked at parking point A2. In FIG. 1, the white arrow indicates the direction of travel of vehicle 10. First, vehicle 10 passes first point A1. First point A1 is the first point where vehicle 10 enters within a first predetermined distance from parking point A2. Here, the first point refers to, for example, the first point entered in the trip immediately before vehicle 10 is parked at parking point A2. Vehicle 10 travels from first point A1 toward first parking lot P1. However, because first parking lot P1 is full, vehicle 10 then travels toward second parking lot P2. However, because second parking lot P2 is also full, vehicle 10 continues traveling toward parking point A2 and is finally parked at parking point A2. In this way, vehicle 10 passes first point A1, first parking lot P1, and second parking lot P2 before arriving at parking point A2. In this way, the vehicle 10 travels around the inside and outside of the first predetermined distance from the parking spot A2 to reach the parking spot A2.

[0017] On the other hand, FIG. 2 is a diagram showing the travel trajectory of vehicle 10 when it is assumed that vehicle 10 travels from first point A1 to parking point A2. In FIG. 2, the outline arrow indicates the traveling direction of vehicle 10. Vehicle 10 travels from first point A1 through intersection A3 and arrives at parking point A2. The difference between the actual travel distance (first distance) of vehicle 10 shown in FIG. 1 and the assumed travel distance (second distance) of vehicle 10 shown in FIG. 2 corresponds to the distance from intersection A3 through first parking lot P1 and second parking lot P2 and back to intersection A3. This difference in distance can be said to be the distance traveled by vehicle 10 in vain while searching for a parking space. The shorter this difference in distance, the shorter the travel time, which increases user satisfaction and reduces traffic congestion.

[0018] Therefore, the server 30 outputs an index corresponding to the behavior of the vehicle 10 before parking, based on a comparison between the first distance and the second distance. For example, this index is an index indicating how far the vehicle 10 traveled to search for a parking space. This index is output, for example, as the difference between the first distance and the second distance. As another example, this index may be output as the ratio between the first distance and the second distance. The server 30, for example, displays the difference between the first distance and the second distance on a display.

[0019] Next, the hardware and software configurations of the vehicle 10 and the server 30 will be described with reference to Fig. 3. Fig. 3 is a block diagram that schematically shows an example of the configuration of the vehicle 10 and the server 30 that constitute the system 1 according to this embodiment. The server 30 has a control unit 31, a storage unit 32, a communication module 33, and an input / output device 34.

[0020] The server 30 can be configured as a computer having a processor (CPU, GPU, etc.), a main memory (RAM, ROM, etc.), and an auxiliary memory (EPROM, hard disk drive, removable media, etc.). The auxiliary memory stores an operating system (OS), various programs, various tables, etc., and by executing the programs stored therein, various functions (software modules) that meet predetermined purposes, as described below, can be realized. However, some or all of the modules may be realized as hardware modules using hardware circuits such as ASICs and FPGAs.

[0021] The control unit 31 is a computing unit that executes predetermined programs to realize various functions of the server 30. The control unit 31 can be realized by a hardware processor such as a CPU. The control unit 31 also includes RAM, ROM (Read Only Memory), It may be configured to include a cache memory, etc. Details of the control unit 31 will be described later.

[0022] The storage unit 32 is a means for storing information, and is configured with a storage medium such as a RAM, a magnetic disk, or a flash memory. The storage unit 32 stores programs executed by the control unit 31, data used by the programs, etc. The storage unit 32 also has databases (a vehicle information DB 321 and a map information DB 322) built therein, and the vehicle information and map information collected from each vehicle 10 are stored in the databases.

[0023] The vehicle information DB 321 stores location information and time information of the vehicle 10, linked to the vehicle ID. The location information and time information are linked to the vehicle ID and transmitted from the vehicle 10 at predetermined time intervals. The vehicle information DB 321 also stores the startup status of the system of the vehicle 10. For example, the time when the system of the vehicle 10 started up (power-on time) and the time when the system shut down (power-off time) are stored. Hereinafter, the vehicle ID, location information, time information, and information related to the startup status of the system of the vehicle 10 are collectively referred to as vehicle information. The control unit 31 stores the vehicle information received from the vehicle 10 in the vehicle information DB 321.

[0024] In addition, the map information DB322 stores map information such as link data relating to roads (links), node data relating to node points, intersection data relating to each intersection, search data for searching routes, section data relating to sections, and lane data relating to the number of lanes.

[0025] The communication module 33 is a communication interface for connecting the server 30 to the network N1. The communication module 33 may be configured to include, for example, a network interface board, a wireless communication interface for wireless communication, etc. The server 30 can perform data communication with each vehicle 10 via the communication module 33.

[0026] The input / output device 34 is a means for receiving input operations performed by an operator and presenting information to the operator. Specifically, the input / output device 34 includes devices for input such as a mouse and a keyboard, and devices for output such as a display and a speaker. The input / output device 34 may be integrally configured with, for example, a touch panel display.

[0027] The specific hardware configuration of the server 30 may include omission, substitution, and addition of components as appropriate depending on the embodiment.

[0028] Next, the vehicle 10 will be described. The vehicle 10 includes a control unit 11, a storage unit 12, a communication module 13, a position information sensor 14, and a power switch. The control unit 11 is a calculation unit that executes predetermined programs to realize various functions of the vehicle 10. The control unit 11 can be realized by a hardware processor such as a CPU. The control unit 11 may also include a RAM, a ROM (Read Only Memory), a cache memory, and the like.

[0029] The storage unit 12 is a means for storing information and is configured with storage media such as RAM, a magnetic disk, a flash memory, etc. The storage unit 12 stores programs executed by the control unit 11, data used by the programs, etc. The storage unit 12 also stores detection values ​​of the position information sensor 14.

[0030] The communication module 13 is a communication means for connecting the vehicle 10 to the network N1. In this embodiment, the vehicle 10 can communicate with other devices (for example, the server 30) via the network N1 using mobile communication services such as 3G, LTE, 5G, and 6G. Cut.

[0031] The position information sensor 14 periodically acquires position information (e.g., latitude and longitude) of the vehicle 10. The position information sensor 14 may be, for example, a GPS (Global Positioning System) receiving unit. , wireless communication unit, etc.

[0032] The power switch 15 is a switch for changing the startup state of the vehicle 10, and is a switch that the driver presses to start the vehicle 10 or to stop the functions of the vehicle 10. Note that a state in which the driver presses the power switch 15 to start the vehicle 10 is called a power-on state, and a state in which the user presses the power switch 15 again to stop the functions of the vehicle 10 is called a power-off state. The power switch 15 may be an IG switch. The power-on state corresponds to the IG-on state, and the power-off state corresponds to the IG-off state.

[0033] The control unit 11 of the vehicle 10 transmits the detection value of the position information sensor 14 and the activation state of the vehicle 10 together with the vehicle ID and time information to the server 30 at predetermined time intervals. In this way, the control unit 11 of the vehicle 10 transmits the vehicle information to the server 30 at predetermined time intervals. Note that the activation state of the vehicle 10 may be transmitted to the server 30 only when the driver operates the power switch 15. Here, if the system of the vehicle 10 is not activated, the server 30 can determine that the vehicle 10 is in a parked state.

[0034] Next, the control unit 31 of the server 30 will be described in detail. The control unit 31 of the server 30 calculates a first distance, which is the actual travel distance of the vehicle 10 from the first point A1 to the parking point A2, based on the vehicle information acquired from the vehicle 10. To this end, the control unit 31 identifies the parking point A2 of the vehicle 10 and the first point A1, which is the point where the vehicle 10 first entered within a first predetermined distance from the parking point A2. The parking point A2 is acquired from the vehicle information, for example, as the point where the system of the vehicle 10 shuts down. The first point A1 is acquired from the vehicle information as the point where the vehicle 10 first entered within the first predetermined distance from the parking point A2 during the trip in which the vehicle 10 moved to the parking point A2. The first distance can be calculated by calculating and accumulating the travel distance between the first point A1 and the parking point A2 from the position of the vehicle 10 at each time.

[0035] Furthermore, the control unit 31 of the server 30 calculates the second distance. Therefore, the control unit 31 generates the shortest route from the first point A1 to the parking point A2. The shortest route is the route with the shortest distance among the routes that the vehicle 10 can travel from the first point A1 to the parking point A2. This shortest route may be the route presented when a route from the first point A1 to the parking point A2 is searched for using a navigation system.

[0036] Then, the control unit 31 calculates the difference between the first distance and the second distance. This difference is called the parking distance difference. The parking distance difference corresponds to the extra distance traveled by the vehicle 10 in order to search for a parking lot. After calculating the parking distance difference, the server 30 outputs the calculated parking distance difference from the input / output device 34. At this time, for example, the parking distance difference is displayed on a display.

[0037] Next, a process for outputting the parking distance difference in the server 30 will be described. FIG. 4 is a flowchart showing a process for outputting the parking distance difference in the server 30 in the first embodiment. The flowchart shown in FIG. 4 is executed for each vehicle 10 in an area (referred to as a target area) that provides an index according to the behavior of the vehicle 10 before parking. Note that the description will be given assuming that the vehicle information DB 321 stores vehicle information corresponding to a plurality of vehicles 10. The target area can be arbitrarily set by the operator of the server 30.

[0038] In step S101, the control unit 31 determines whether the vehicle 10 is parked. For example, the control unit 31 determines that the vehicle 10 is parked when the state changes from a power-on state (which may be an IG-on state) to a power-off state (which may be an IG-off state). The state of the power switch 15 (which may be an IG switch) is included in the vehicle information transmitted from the vehicle 10 and is stored in the vehicle information DB 321. If the determination in step S101 is affirmative, the process proceeds to step S102, and if the determination is negative, the routine is terminated.

[0039] In step S102, the control unit 31 extracts vehicle information of the target vehicle 10 from the vehicle information DB 321. In step S103, the control unit 31 acquires a parking spot A2. The control unit 31 acquires the position of the vehicle 10 at the time the power switch 15 of the vehicle 10 is turned off as the parking spot A2. Next, in step S104, the control unit 31 acquires a first point A1. The control unit 31 acquires the first point within a first predetermined distance (e.g., 1 km) from the parking spot A2 as the first point A1. At this time, the first point A1 is identified from the transition of the position of the vehicle 10 in the trip when the vehicle 10 arrives at the parking spot A2.

[0040] In step S105, the control unit 31 calculates a first distance. The control unit 31 calculates the distance that the vehicle 10 actually traveled from the first point A1 acquired in step S104 to the parking point A2 acquired in step S103. At this time, the control unit 31 calculates the distance that the vehicle 10 actually traveled from the transition of the position of the vehicle 10. In step S106, the control unit 31 generates the shortest route from the first point A1 acquired in step S104 to the parking point A2 acquired in step S103. The control unit 31 generates the shortest route using information stored in the map information DB 322. A known technique can be used to generate this shortest route. Note that in this routine, the shortest route is generated. However, as another example, a route based on the travel history of another vehicle 10 may be generated. For example, the shortest route among the routes that the other vehicle 10 traveled from the first point A1 to the parking point A2 may be generated in step S106. As yet another example, the route traveled by the most vehicles 10 among the routes traveled by other vehicles 10 from the first point A1 to the parking point A2 may be generated in step S106. In this way, by using the routes actually traveled by other vehicles 10 as the comparison target, a realistic index can be obtained. As another example, a route connecting the first point A1 and the parking point A2 in a straight line may be generated in step S106. In this way, the shortest route can be generated easily without requiring map data. Therefore, the cost of using map data and the cost of searching for the shortest route are not required.

[0041] In step S107, the control unit 31 calculates the second distance. The control unit 31 calculates the distance of the shortest route generated in step S106 based on the map information stored in the map information DB 322. A known technique can be used for this calculation. As another example, if a route connecting the first point A1 and the parking point A2 in a straight line is generated in step S106, the first predetermined distance used in step S104 can be used as the second distance.

[0042] In step S108, control unit 31 calculates the parking distance difference. Control unit 31 calculates the parking distance difference by subtracting the second distance calculated in step S107 from the first distance calculated in step S105. Then, in step S108, control unit 31 outputs the parking distance difference calculated in step S108 as an index according to the behavior of vehicle 10 before parking. Note that the parking distance difference calculated in step S108 may be stored in memory unit 32, and the parking distance difference may be output in response to a request from the operator.

[0043] As described above, according to this embodiment, the parking distance difference can be calculated and provided as an index according to the behavior of the vehicle 10 before parking at the parking spot A2. This makes it possible to quantify how far a vehicle 10 has driven around in search of a parking space. In other words, it becomes possible to determine how much unnecessary distance the vehicle 10 traveled before parking. This index correlates with the level of user dissatisfaction and the likelihood of traffic congestion, and can therefore be used to improve these. It is also possible to provide the percentage of vehicles 10 that drove around in search of a parking space.

[0044] Second Embodiment In the second embodiment, the parking distance difference is calculated only for vehicles 10 whose distance from the departure point of the vehicle 10 to the parking point A2 is equal to or greater than a second predetermined distance. The parking distance difference provided in the first embodiment can be used as an indicator for, for example, tourists driving around a tourist spot looking for a parking space. However, including cases where people living in the tourist spot drive around the tourist spot to do daily shopping or other activities would defeat the purpose. Therefore, in the second embodiment, the parking distance difference is provided while excluding the behavior of local resident's vehicles 10. Here, local resident's vehicles 10 are considered to have departure points that are relatively close to the parking point A2. Therefore, by calculating the parking distance difference only for vehicles 10 whose distance from the departure point of the vehicle 10 to the parking point A2 is equal to or greater than a second predetermined distance, local resident's vehicles 10 can be excluded. The second predetermined distance is stored in the memory unit 32 as a distance at which local resident's vehicles 10 can be excluded.

[0045] Next, a process for outputting a parking distance difference in the server 30 will be described. Fig. 5 is a flowchart showing a process for outputting a parking distance difference in the server 30 in the second embodiment. The flowchart shown in Fig. 5 is executed for each vehicle 10 in the target area. Note that the description will be given assuming that the vehicle information DB 321 stores vehicle information corresponding to a plurality of vehicles 10. Also, a description of steps in which the same process as in the flowchart shown in Fig. 4 is executed will be omitted.

[0046] In the flowchart shown in FIG. 5, once the processing of step S103 is completed, the process proceeds to step S201. In step S201, the control unit 31 acquires a starting point. The starting point is the point from which the vehicle 10 departs in the trip in which the vehicle 10 moves to the parking spot A2. This starting point is the point at which the power switch 15 is operated to change from a power-off state to a power-on state. In step S202, the control unit 31 calculates the distance from the parking spot A2 acquired in step S103 to the starting point acquired in step S201. This distance is, for example, a straight-line distance. Then, in step S203, the control unit 31 determines whether the distance calculated in step S202 is equal to or greater than a second predetermined distance. If a positive determination is made in step S203, the process proceeds to step S104; if a negative determination is made, the control unit 31 ends this routine.

[0047] As described above, according to this embodiment, it is possible to provide an index according to the behavior of the vehicle 10 before parking with higher accuracy.

[0048] <Other embodiments> The above embodiment is merely an example, and the present invention may be modified and implemented as appropriate within the scope of the gist thereof. The processes and means described in this disclosure may be freely combined and implemented as long as no technical contradictions arise. Furthermore, a process described as being performed by one device may be shared and executed by multiple devices. Alternatively, a process described as being performed by different devices may be executed by a single device. In a computer system, the hardware configuration (server configuration) by which each function is realized can be flexibly changed.

[0049] Furthermore, for example, the first predetermined distance for identifying the first point may be set according to the density of parking lots. For example, if the distance between parking lots is long and the first predetermined distance is set relatively short, the vehicle 10 may drive around in search of a parking lot outside the first predetermined distance. Therefore, a more realistic indicator can be obtained by setting the first predetermined distance according to the range in which the vehicle 10 is expected to drive around. Therefore, the lower the density of parking lots, the longer the first predetermined distance may be.

[0050] The control unit 31 may further be configured to: acquire a first percentage during a busy period, which is the percentage of vehicles 10 for which the difference between the first distance and the second distance is equal to or greater than a predetermined difference; acquire a second percentage during an off-peak period, which is the percentage of vehicles 10 for which the difference between the first distance and the second distance is equal to or greater than a predetermined difference; and output the percentage obtained by subtracting the second percentage from the first percentage as the percentage of vehicles 10 that searched for a parking space during the busy period. Here, the behavior during the off-peak period is considered to correspond to the daily life of local residents. Furthermore, local residents' vehicles 10 exhibit similar behavior during the busy period as during the off-peak period. Because this behavior is not behavior associated with searching for a parking space, excluding it from the percentage of vehicles 10 that searched for a parking space during the busy period can improve the accuracy of the index.

[0051] Furthermore, when the vehicle 10 stops at a predetermined facility, the control unit 31 may acquire the distance that the vehicle 10 actually traveled from the predetermined facility to the parking spot A2 as the first distance. Here, the travel to the predetermined facility where pick-up and drop-off are performed is not a behavior for searching for a parking lot, so the accuracy of the index can be improved by treating the subsequent behavior as the behavior of the vehicle 10 searching for a parking lot. The predetermined facility is, for example, a station or a school.

[0052] The present invention can also be realized by supplying a computer program that implements the functions described in the above embodiments to a computer, and having one or more processors in the computer read and execute the program. Such a computer program may be provided to the computer on a non-transitory computer-readable storage medium connectable to the computer's system bus, or may be provided to the computer via a network. Non-transitory computer-readable storage media include, for example, any type of disk, such as a magnetic disk (e.g., a floppy disk, a hard disk drive (HDD), etc.), an optical disk (e.g., a CD-ROM, a DVD disk, a Blu-ray disk), a read-only memory (ROM), a random access memory (RAM), an EPROM, an EEPROM, a magnetic card, a flash memory, an optical card, or any type of medium suitable for storing electronic instructions.
