Description

The present invention relates to a parking information analysis device and a parking information analysis method for analyzing information about parking.

In a large parking lot such as a commercial complex, a plurality of parking areas and a plurality of doorways are often provided for the convenience of visitors.
However, in reality, there are cases where these multiple areas and multiple gateways are not effectively utilized. For example, a vehicle of a visitor of a facility may concentrate and park in a specific parking area. In this case, when returning home, the vehicles returning home in the same direction are concentrated at a specific entrance/exit, so that the specific entrance/exit becomes crowded.

A technique considering such a problem is disclosed in, for example, Patent Document 1. In the technique disclosed in Patent Document 1, a computer generates a virtual vehicle on a parking lot and its surrounding roads that are assumed by the data in the storage device. Then, the generated virtual vehicle is randomly moved to be parked in the parking lot, and the result is displayed on the display device. In this way, by simulating the flow of vehicles in the parking lot in advance, it is possible to make a traffic plan based on the simulation result.

Hereinafter, a preferred embodiment of the parking information analysis system of the present invention will be described in detail with reference to the drawings.

<Overall configuration of parking information analysis system 1>
A parking information analysis system 1 according to a preferred embodiment of the present invention will be described. FIG. 1 shows the overall configuration of the parking information analysis system 1.

As shown in FIG. 1, the parking information analysis system 1 includes an in-vehicle navigation device 10, a mobile terminal 20, a parking information analysis device 30, and a facility terminal 40. These devices and terminals are connected to each other via a communication network 60 so that they can communicate with each other. It should be noted that although information transmitted and received by each of these devices and terminals is also shown in the drawing, these information are merely examples. In this embodiment, information other than the illustrated information may be transmitted and received.

The vehicle-mounted navigation device 10 is a device that performs navigation (route guidance) for a user who has boarded the vehicle 50a. The in-vehicle navigation device 10 also has a function of positioning the positional information of the in-vehicle navigation device 10 (that is, the positional information of the vehicle 50a). The vehicle-mounted navigation device 10 provides route guidance from the current position to the destination based on the request from the user who gets in the vehicle 50 and the position information obtained by positioning.

The in-vehicle navigation device 10 also appropriately transmits the measured position information to the parking information analysis device 30 together with the moving body ID that is identification information for identifying the in-vehicle navigation device 10. Here, since the vehicle-mounted navigation device 10 and the vehicle 50a are used as a one-to-one set, the transmitted position information can be regarded substantially as the position information of the vehicle 50a.
Such an on-vehicle navigation device 10 can be realized by a car navigation device that is installed and portable in a vehicle 50a that is a moving body, or a PND (Portable Navigation Device) that is simply installed in the vehicle 50a that is a moving body. You can

The mobile terminal 20 is a mobile terminal used by a user in the vehicle 50b. The mobile terminal 20 has a function of performing navigation (route guidance) and a function of positioning the position information of the mobile terminal 20 (that is, the position information of the vehicle 50b) similarly to the in-vehicle navigation device 10 described above.

Then, similarly to the in-vehicle navigation device 10 described above, the mobile terminal 20 sends the measured position information to the parking information analysis device 30 together with the moving body ID that is the identification information for identifying the mobile terminal 20. Send as appropriate. Here, since the mobile terminal 20 and the vehicle 50b are used as a one-to-one pair, the transmitted position information can be substantially regarded as the position information of the vehicle 50b.
Such a mobile terminal 20 can be realized by a smartphone, a mobile phone, a tablet terminal, a notebook computer, or other portable electronic device.

It should be noted that in the figure, one set each of the vehicle-mounted navigation device 10 and the vehicle 50a and one set of the mobile terminal 20 and the vehicle 50b are shown, but the number of these sets is not particularly limited, and the present embodiment is not limited thereto. May include any number of these sets. Similarly, the number of parking information analysis devices 30 and facility terminals 40 is not particularly limited, and the present embodiment may include any number of parking information analysis devices 30 and facility terminals 40.

Further, in the following description, when the vehicle 50a equipped with the in-vehicle navigation device 10 and the vehicle 50b on which the user of the mobile terminal 20 rides are referred to without distinction, the alphabet at the end is omitted and simply It is called "vehicle 50".
Further, the vehicle 50, the in-vehicle navigation device 10 and the mobile terminal 20 used in the vehicle 50 move as the vehicle 50 moves. Therefore, in the following description, the vehicle 50, the vehicle-mounted navigation device 10, and the mobile terminal 20 are appropriately referred to as “moving bodies”.

The parking information analysis device 30 is a device that performs an analysis for suppressing congestion based on an actual parking situation in a parking lot such as a commercial facility. The facility targeted for this analysis is not particularly limited. For example, a facility such as a large shopping center having a plurality of parking areas and a plurality of doorways can be analyzed as a parking lot.

In a specific analysis, the parking information analysis device 30 identifies the departure positions of the plurality of moving bodies based on the transition of the received location information, and determines the plurality of departure positions of the plurality of moving bodies based on the identified departure positions of the plurality of moving bodies. Estimate the direction of return from the mobile facility. In addition, the parking information analysis device 30 identifies the parking position of the moving body parked in the parking lot of the facility based on the transition of the received position information.
Then, the parking information analysis device 30 newly parks in the parking lot of the facility based on the estimated return home directions of the plurality of moving bodies from the facility and the parking positions of the mobile bodies parked in the parking lot of the specified facility. The recommended parking positions of the moving bodies to be moved are calculated so that the moving bodies in the same returning direction are dispersed.

In this way, the parking information analysis device 30 can calculate the recommended parking position for suppressing congestion when returning home, based on the actual parking situation and the like. That is, the parking information analysis device 30 can perform analysis for suppressing congestion based on the actual parking situation and the like.

In addition, the parking information analysis device 30 notifies the user of the moving body of the recommended parking position by using the facility terminal 40 described later. The mobile user can avoid congestion when returning home by parking at the notified recommended parking position. As a result, the convenience of the user of the mobile body can be improved.
In this case, the user of the mobile body can avoid congestion in the parking lot, and thus it is assumed that the user stays in the facility for a longer time. In addition, along with this, consumption at the facility is expected to increase and sales sales at the facility can be expected to increase. Further, it is possible to suppress the occurrence of traffic congestion on the road near the facility.

In this way, the parking information analysis device 30 can generate various benefits in the facility. This parking information analysis device 30 can be variously used by many businesses. For example, it may be used by an operator of a facility that enjoys the above-mentioned benefits. Alternatively, it may be used by a business operator who obtains a cost from the facility operator by consulting with the facility operator.
Such a parking information analysis device 30 can be realized by, for example, a server device.

The facility terminal 40 is a terminal used in the facility. The facility terminal 40 acquires the recommended parking position from the parking information analysis device 30. Then, the facility terminal 40 notifies the user of the moving body of the acquired recommended parking position. As described above, the user of the mobile body can avoid the congestion when returning home by parking at the notified recommended parking position.
Such a facility terminal 40 can be realized by a personal computer, for example.

The vehicle 50 is a moving body on which a user of the vehicle-mounted navigation device 10 or the mobile terminal 20 rides. The vehicle 50 is realized by, for example, a four-wheeled vehicle, a motorcycle, a bicycle, or the like.

The communication network 60 is realized by a network such as the Internet or a mobile phone network, or a network combining these. A LAN (Local Area Network) may be included in a part of the network (for example, between the parking information analysis device 30 and the facility terminal 40).

<Functional block of the in-vehicle navigation device 10>
Next, the functional blocks included in the vehicle-mounted navigation device 10 will be described with reference to the block diagram of FIG.
Here, the vehicle-mounted navigation device 10 is supplied with power from the vehicle 50a, and is automatically started by turning on an ignition switch of the vehicle 50a (starting an engine) by a user who gets on the vehicle 50a. Then, the vehicle-mounted navigation device 10 operates until the user who gets in the vehicle 50a turns off the ignition switch of the vehicle 50a (stops the engine).

As shown in FIG. 2, the vehicle-mounted navigation device 10 includes a control unit 11, a storage unit 12, a communication unit 13, a sensor unit 14, a display unit 15, and an input unit 16.

The control unit 11 includes an arithmetic processing device such as a microprocessor, and controls each unit included in the vehicle-mounted navigation device 10. Details of the control unit 11 will be described later.

The storage unit 12 is configured by a semiconductor memory or the like, and for performing a control program called firmware or an operating system, a program for performing route guidance processing, or a process of transmitting position information to the parking information analysis device 30. In addition to various programs such as the above program, various information such as facility information for route guidance and map information including a facility ID is stored.

Each piece of information stored in the storage unit 12 may be stored in the storage unit 12 in advance, may be appropriately updated by the control unit 11, or may be connected to the communication network 60. The configuration may be appropriately downloaded from a server device (not shown) or the like as necessary. Further, it may be appropriately modified according to the user's input or the like.

In the figure, as the information stored in the storage unit 12, the position information 121 and the moving body ID 122, which are information regarding the transmission processing of the position information, are illustrated.
The position information 121 is the position information of the vehicle-mounted navigation device 10 (that is, the position information of the vehicle 50a) measured by the sensor unit 14 described later. The position information 121 may include not only the information indicating the position where the positioning is performed but also the time when the positioning is performed.

The moving body ID 122 is information for identifying the vehicle-mounted navigation device 10 and the vehicle 50a in which the vehicle-mounted navigation device 10 is installed.
As the mobile body ID 122, for example, a manufacturing number or the like uniquely assigned to the vehicle-mounted navigation device 10 can be used. In addition, in order for the communication unit 13 to connect to the communication network 60 which is a network such as a mobile phone network, the mobile body ID 122 is the telephone number assigned to the SIM (Subscriber Identity Module) inserted in the communication unit 13. Can be used as In addition, the VIN (vehicle identification number) uniquely assigned to the vehicle 50a or the number of the license plate can be used as the moving body ID 122.

The communication unit 13 has a DSP (Digital Signal Processor) and the like and is compliant with standards such as LTE (Long Term Evolution) established by 3GPP (Third Generation Partnership Project) and standards such as Wi-Fi (registered trademark). Thus, wireless communication with another device (for example, the parking information analysis device 30) is realized via the communication network 60. The communication unit 13 is used, for example, by the position information transmission unit 112, which will be described later, to transmit the position information 121 and the mobile body ID 122 stored in the storage unit 12 to the parking information analysis device 30. However, the data transmitted and received between the communication unit 13 and another device is not particularly limited, and information other than the position information 121 and the mobile body ID 122 may be transmitted and received.

The sensor unit 14 includes, for example, a GPS (Global Positioning System) sensor, a gyro sensor, an acceleration sensor, and the like. The sensor unit 14 has a function as a position detection unit that detects position information, receives a GPS satellite signal by a GPS sensor, and measures the position information (latitude and longitude) of the vehicle-mounted navigation device 10. Positioning by the sensor unit 14 is performed at predetermined time intervals (for example, 3 second intervals) as described above. Positioned position information is stored in the storage unit 12 as position information 121.
The sensor unit 14 can further improve the positioning accuracy of the position information of the vehicle-mounted navigation device 10 based on the angular velocity measured by the gyro sensor or the acceleration sensor or the acceleration.
In addition, when GPS communication is difficult or impossible, the sensor unit 14 uses AGPS (Assisted Global Positioning System) communication and uses the base station information acquired from the communication unit 13 to determine the position information of the vehicle-mounted navigation device 10. It is also possible to calculate

The display unit 15 is composed of a display device such as a liquid crystal display or an organic electroluminescence panel. The display unit 15 displays an image in response to an instruction from the control unit 11. The information displayed by the display unit 15 includes, for example, the current position of the vehicle-mounted navigation device 10, map information around the current position of the vehicle-mounted navigation device 10 read from the map information, destinations set by the user, other vehicle-mounted devices. The meeting information, route information, various user interfaces, etc. notified from the navigation device 10 are listed.

The input unit 16 includes a physical switch called a numeric keypad, an input device (not shown) such as a touch panel provided on the display surface of the display unit 15, and the like. By outputting to the control unit 11 a signal based on an operation input from the input unit 16, for example, a user pressing a ten-key pad or a touch on the touch panel, it is possible to realize a user's selection operation or map enlargement/reduction operation. it can.

In addition, although not shown, a speaker, a microphone and the like may be provided. The speaker outputs a voice to the driver, and the microphone collects a voice or the like emitted by the driver.
By doing so, it is possible to output information from the speaker by voice or input various selections and instructions by the driver, which are voice-input through the microphone, to the control unit 11 by the voice recognition technology.

Next, details of the control unit 11 will be described. The control unit 11 is configured by a microprocessor having a CPU (Central Processing Unit), a RAM (Random access memory), a ROM (Read Only Memory), and an I/O (Input/output). The CPU executes each program read from the ROM or the storage unit 12, at the time of execution, reads information from the RAM, ROM, and storage unit 12, writes information to the RAM and storage unit 12, It exchanges signals with the communication unit 13, the sensor unit 14, the display unit 15, and the input unit 16. In this way, the processing in the present embodiment is realized by the cooperation of the hardware and the software (program).

The control unit 11 includes a route guidance unit 111 and a position information transmission unit 112 as functional blocks.

The route guidance unit 111 is a part that performs route guidance processing to a destination such as a facility or the like input or selected by the user.
The route guidance process to the destination is the same as the route guidance process in a general car navigation system. That is, the route guidance unit 111 generates a map up to the destination based on the map information (not shown) stored in the storage unit 12, and the sensor unit 14 measures the position on the generated map. The current position of the vehicle-mounted navigation device 10, the position of the destination, and the route information to the destination are overlapped and displayed on the display unit 15 to provide route guidance. In this case, a voice for route guidance may be further output from a speaker (not shown). Further, information on the congestion status of the road, information on the weather, and the like may be acquired through communication by the communication unit 13, and the acquired information may be used for route guidance processing.
Since the route guidance processing to the destination is well known to those skilled in the art, further detailed description will be omitted.

The position information transmission unit 112 is a unit that transmits the position information 121 and the mobile body ID 122 stored in the storage unit 12 to the parking information analysis device 30 by wireless communication using the communication unit 13.

The transmission of the position information 121 and the moving body ID 122 to the parking information analysis device 30 by the position information transmitting unit 112 is performed by the user who gets on the vehicle 50a at the start of driving to turn on the ignition switch of the vehicle 50a (start the engine), This is periodically performed after the vehicle-mounted navigation device 10 is automatically started until the ignition switch of the vehicle 50a is turned off (engine is stopped) at the end of driving. For example, each time the sensor unit 14 performs positioning at a predetermined time interval (for example, every 3 seconds), transmission is performed in real time. That is, transmission is performed in real time until the drive is started once and this drive is ended.
Further, instead of transmitting to the parking information analysis device 30 in real time, a plurality of them are collected together (for example, the location information 121 updated at intervals of 3 seconds and the moving body ID 122 are collected together for 3 minutes) at a time. You may make it transmit. That is, so-called burst transmission may be performed. The length of the predetermined time interval and whether to transmit in real time or burst transmission can be arbitrarily set according to the environment to which the present embodiment is applied and the like.
In this way, by performing the real-time transmission or the burst transmission, the position information transmission unit 112 parks the position information 121 for specifying the movement route of the vehicle 50a positioned by the sensor unit 14 and the moving body ID 122. It transmits to the information analysis device 30.

In this case, the ignition switch is turned on (the engine is started), and the position specified by the position information 121 immediately after the vehicle-mounted navigation device 10 is automatically started is parked as the first vehicle position in the drive, that is, the starting position. It can be transmitted to the information analysis device 30. Furthermore, the position specified by the position information 121 positioned immediately before the ignition switch is turned off (engine stopped) can be transmitted to the parking information analysis device 30 as the final vehicle position in the drive, that is, the parking position. For example, information indicating that it is the position information 121 indicating the departure position or the position information 121 indicating the parking position (for example, the value of the flag indicating these is set to 1) is added to the position information 121. To the parking information analysis device 30.
Regarding the position information 121 (that is, the parking position) measured immediately before the ignition switch is turned off (engine stopped), when the ignition switch is turned on (engine started) and the vehicle-mounted navigation device 10 is started again. May be sent to.

Further, even when performing the burst transmission, when the route guidance unit 111 determines that the vehicle 50a has arrived at the destination such as the facility, the position information transmission unit 112 performs the transmission in real time. You should switch. In this way, after the vehicle arrives at the destination such as the facility and before the position information 121 of the destination such as the facility is transmitted, the ignition switch is turned off (engine stopped), and the position of the destination such as the facility is reached. It is possible to prevent a situation in which the information 121 is not transmitted to the parking information analysis device 30.

Further, the position information transmission unit 112 may also transmit the information on the destination set in the route guidance unit 111 to the parking information analysis device 30, together with the position information 121 and the moving body ID 122 described above.
For example, when the user sets a destination in the route guidance unit 111, the position information transmission unit 112, based on the route guidance map information (not shown) stored in the storage unit 12, the destination. The location information (latitude and longitude) and the facility ID of the facility corresponding to this destination are acquired. Then, the position information transmitting unit 112 transmits these pieces of acquired information to the parking information analysis device 30 as information on the destination.
As a result, the returning-home direction estimation unit 312 in the parking information analysis device 30 described below can specify the facility that the vehicle 50 is going to visit.
The destination information may also include the estimated arrival time to the destination calculated by the route guidance unit 111. As a result, the returning-home direction estimation unit 312 in the parking information analysis device 30, which will be described later, can also specify the estimated arrival time at the facility that the vehicle 50 is going to visit.

<Functional block of mobile terminal 20>
Next, the functional blocks included in the mobile terminal 20 will be described with reference to the block diagram of FIG.
Here, the above-described vehicle-mounted navigation device 10 is supplied with power from the vehicle 50a, but the mobile terminal 20 is supplied with power from a battery (not shown) included therein. However, the mobile terminal 20 may be supplied with power from a cigar socket or the like of the vehicle 50b in order to charge the battery.

As shown in FIG. 3, the mobile terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, a sensor unit 24, a display unit 25, an input unit 26, and a short-range communication unit 27. Composed of.
Here, the control unit 21, the storage unit 22, the communication unit 23, the sensor unit 24, the display unit 25, and the input unit 26 have the same functions as the functional blocks of the same name included in the in-vehicle navigation device 10 described above. Have That is, in the description of the in-vehicle navigation device 10 described above, the words "in-vehicle navigation device 10" are replaced with "portable terminal 20" and the words "vehicle 50a" are replaced with "vehicle 50b". Since this is a description of the functional blocks, duplicated description will be omitted.

On the other hand, the mobile terminal 20 differs from the vehicle-mounted navigation device 10 in that it includes the short-range communication unit 27, and so on, and the difference will be described below.
The short-distance communication unit 27 performs non-contact short-distance communication conforming to standards such as NFC (Near Field Communication) and Bluetooth (registered trademark) or wired short-distance communication via a USB (Universal Serial Bus) cable or the like. It is a part for.

On the other hand, the vehicle 50b includes a short-range communication unit for communicating with the short-range communication unit 27. For example, an ECU (Electronic Control Unit) of the vehicle 50b includes a short-range communication unit.
Then, the case where the mobile terminal 20 can communicate with the ECU by short-range communication is, that is, the case where the mobile terminal 20 is present inside the vehicle 50b. In this case, the position information measured by the sensor unit 24 of the mobile terminal 20 corresponds to the position information of the vehicle 50b.

Therefore, the portable terminal 20 activates the position information transmission unit 212 while the short-range communication with the ECU is possible via the short-range communication unit 27. Then, the activated position information transmitting unit 212, similar to the position information transmitting unit 112 of the vehicle-mounted navigation device 10, the position information 221 for specifying the movement route of the vehicle 50b positioned by the sensor unit 24 and the moving body ID 222. And are transmitted to the parking information analysis device 30.

For example, when the user carries the portable terminal 20 into the vehicle 50b and turns on an activation switch of the vehicle 50b such as an ignition switch, the vehicle 50b and the portable terminal 20 are connected (paired) with each other. Positioned position information 221 and moving body ID 222 are transmitted from the mobile terminal 20 to the parking information analysis device 30. In this case, the position specified by the position information 121 positioned immediately after the pairing of the vehicle 50b and the mobile terminal 20 can be transmitted to the parking information analysis device 30 as the first vehicle position in the drive, that is, the starting position.

Further, when the start switch of the vehicle 50b such as an ignition switch is turned off, the pairing between the vehicle 50b and the mobile terminal 20 is released. In this case, the position specified by the position information 121 positioned immediately before the cancellation can be transmitted to the parking information analysis device 30 as the final vehicle position in the drive, that is, the parking position.

In this case, real-time transmission may be performed, burst transmission may be performed, burst transmission may be switched to real-time transmission when it is determined that the destination has been reached, and departure position may be set. Alternatively, information indicating that the vehicle is at the parking position may be added, the parking position may be transmitted at the time of restart, or the information on the destination set in the route guidance unit 211 may be transmitted. The points are the same as those of the position information transmitting unit 112.

In addition, when the vehicle 50b has a function of measuring the position information, the position information measured by the vehicle 50b is transmitted as the position information 121 to the parking information analysis device 30 instead of the position information measured by the sensor unit 24. You may do so. In this case, the sensor unit 24 may be omitted from the mobile terminal 20.

<Functional blocks included in the parking information analysis device 30>
Next, the functional blocks included in the parking information analysis device 30 will be described with reference to the block diagram of FIG.

As shown in FIG. 4, the parking information analysis device 30 includes a control unit 31, a storage unit 32, and a communication unit 33.

The control unit 31 is composed of an arithmetic processing device such as a microprocessor, and controls each part of the parking information analysis device 30. Details of the control unit 31 will be described later.

The storage unit 32 is composed of a semiconductor memory and the like, and stores various programs such as control programs called firmware and operating system, programs for performing service providing processing, and various other information such as map information. Remembered. In the figure, the map information 321 and the parking information database 322, which are information relating to the service providing process, are illustrated as the information stored in the storage unit 32.

The map information 321 includes information about features such as roads and facilities, road information, facility information, parking lot information, and the like. Further, in addition to the map information 321, display map data for displaying backgrounds such as roads and road maps, position information of nodes (for example, road intersections, bending points, end points, etc.) and their type information, It includes position information and type information of links that are routes connecting nodes, road network data including link cost data relating to cost information (for example, distance, required time, etc.) of all links, and the like.

As road information, so-called road map information such as road types and traffic lights is stored.
As the facility information, position information of each facility is stored as latitude and longitude information. As the facility location information, the facility identification information (facility ID), name, facility type (and/or genre), phone number, address, business hours, menu provided if the facility is a restaurant, product service, etc. Additional information such as facility information may be included.

As the parking lot information, the positional information of the parking lot and the positional information of the entrance/exit connecting the parking lot and the road are stored as the latitude/longitude information. When the parking lot is a parking lot attached to each facility, the facility and the parking lot are linked and stored. In addition, if there are multiple parking lots in one facility, one parking lot is divided into multiple parking areas, and there are multiple entrances and exits, the information for identifying these is also linked. It is saved together.

The map information 321 may be stored in the storage unit 32 in advance, or may be appropriately downloaded from a server device (not shown) connected to the communication network 60 as necessary. .. Further, the map information 321 may be appropriately modified according to the user's input or the like.

The parking information database 322 is a database constructed based on the position information 121 and the moving body ID 122 received from the vehicle-mounted navigation device 10, the position information 221 and the moving body ID 222 received from the mobile terminal 20.
The parking information database 322 is constructed and updated by each functional block included in the control unit 31. Details of the parking information database 322 will be described later with reference to FIG. 5 when the movement transition update unit 311 is described.

In the following description, when the position information 121 and the position information 221 are described without distinction, the reference numerals are omitted and the position information is referred to as “position information”. Similarly, when the mobile body ID 122 and the mobile body ID 222 are described without distinction, the reference numerals will be omitted and will be referred to as “mobile body ID”.

The communication unit 33 has a DSP and the like, and is compliant with standards such as LTE defined by 3GPP and standards such as Wi-Fi (registered trademark), and other devices (for example, in-vehicle navigation system) via the communication network 60. The wireless communication and the wired communication with the device 10, the mobile terminal 20, and the facility terminal 40) are realized. The communication unit 33 is used, for example, to receive position information, user information, and a mobile body ID transmitted from each of the vehicle-mounted navigation device 10 and the mobile terminal 20. In addition, the communication unit 33 is also used to transmit the recommended parking position to the facility terminal 40, for example.
However, the data transmitted/received between the communication unit 33 and another device is not particularly limited, and information other than these information may be transmitted/received.

Next, details of the control unit 31 will be described. The control unit 31 is composed of a microprocessor having a CPU, a RAM, a ROM, an I/O and the like. The CPU executes each program read from the ROM or the storage unit 32, reads the information from the RAM, the ROM, and the storage unit 32 at the time of execution, and writes the information to the RAM and the storage unit 32. It exchanges signals with the communication unit 33. In this way, the processing in the present embodiment is realized by the cooperation of the hardware and the software (program).

The control unit 31 includes a movement transition update unit 311, a return home direction estimation unit 312, a recommended parking position calculation unit 313, and a notification unit 314 as functional blocks.
The movement transition update unit 311 is a unit that updates the parking information database 322 based on the position information and the moving body ID received by the communication unit 33 from the moving body, and the map information 321.

An example of the data structure of the parking information database 322 will be described with reference to FIG. As shown in FIG. 5, the parking information database 322 includes “moving body ID”, “movement transition”, “departure position”, “parking position”, “visit facility”, and “return home direction” as attributes. It should be noted that these pieces of information shown in FIG. 5 are stored in association with each other for each drive.

As described above, the “moving body ID” in the parking information database 322 is information for identifying the vehicle-mounted navigation device 10 or the mobile terminal 20 that is the transmission source of the position information or the like, and the vehicle 50 equipped with these. ..
The “movement transition” in the parking information database 322 is all position information received from the start to the end of the transmission of position information and the like. With all of this position information, it is possible to specify the movement transition (that is, the movement route of the vehicle 50) from the starting position to the parking position in one drive. The movement transition may include the time when the positioning of the position information is performed.

The “departure position” in the parking information database 322 is information for identifying the position where the user departs from the vehicle 50 in the drive. The movement transition update unit 311 identifies the departure position from the position information received together with the moving body ID. For example, as described above, when the position information includes information indicating the departure position, the information indicating the departure position is stored in the departure position field in the parking information database 322.
If the position information does not include the information indicating the departure position, for example, the position corresponding to the first position information received after the transmission of the position information etc. is considered to be the departure position. You can also

The “parking position” in the parking information database 322 is information for identifying the position where the user has arrived by the vehicle 50 in driving. The movement transition updating unit 311 identifies the parking position from the position information received together with the moving body ID. For example, as described above, when the position information includes information indicating the parking position, the information indicating the parking position is stored in the parking position field in the parking information database 322. If the position information does not include the information indicating the parking position, for example, the position information is not transmitted for a predetermined period of time after the position information is transmitted once and finally received. In this case, the position corresponding to the last received position information can be regarded as the parking position. In addition, when the position corresponding to the transmitted position information does not change for a certain time or longer, this position can be regarded as the parking position.

Each time the movement transition updating unit 311 receives position information or the like from the vehicle-mounted navigation device 10 and the mobile terminal 20, based on the received information, the “moving body ID”, the “movement transition” in the parking information database 322, The "departure position" and the "parking position" are updated.

On the other hand, the “visiting facility” and the “return home direction” in the parking information database 322 are updated by the return home direction estimation unit 312 described later.
The “visit facility” in the parking information database 322 is information for identifying the facility visited by the user by the vehicle 50 in the drive.
The “return home direction” in the parking information database 322 is information for specifying the return home direction when the user returns home from the visiting facility visited by the vehicle 50. Note that the word “go home” is used for convenience, but in the following description, the case of returning from a facility to a place other than home (for example, the user's work place) will also be referred to as “go home”.

The return-home direction estimation unit 312 is a part that identifies the visiting facility that is the destination in the drive by the vehicle 50 and estimates the returning direction when returning home from this visiting facility. Here, the visiting facility which is the destination specified by the return-home direction estimation unit 312 is the visiting facility corresponding to the future destination (that is, the facility to be visited in the future) and the visiting facility corresponding to the current destination ( That is, it may be either one of the facilities currently being visited) or both.

Various methods are conceivable as the method for the returning-home direction estimation unit 312 to specify the visited facility that is the destination.
For example, the returning-home direction estimation unit 312 can identify the visited facility that is the destination by referring to the parking information database 322. In this case, the returning-home direction estimation unit 312 compares the movement transition and the parking position in the parking information database 322 with the position of the facility included in the map information 321 (or the position of the parking lot associated with the facility). By doing so, the visited facility that is the destination is specified.

In addition, for example, the returning-home direction estimation unit 312 can specify the visiting facility that is the destination of the current drive from the movement route of the current drive and the movement route of the past drive. For example, the movement route in the current drive and the movement route in the past drive are compared to identify the movement route in the past drive that is the closest to the movement route in the current drive. Then, the parking position on the movement route in the past drive is regarded as the parking position on the movement route in the current drive. Then, as described above, it is possible to specify the visited facility which is the destination of the current drive from the parking position which is regarded as the parking position of the moving route of the current drive.

Alternatively, when the return home direction estimation unit 312 receives the information about the destination in the route guidance from the moving body, the returning home direction estimation unit 312 may specify the visited facility as the destination based on the information about the destination. it can. For example, when the location information of the visited facility which is the destination or the facility ID of the visited facility which is the destination is received from the moving body as the information of the destination in the route guidance, this information and the map By comparing the information 321, it is possible to specify the visited facility which is the destination.

The returning-home direction estimation unit 312 updates the “visit facility” in the parking information database 322 when the visited facility that is the destination is specified. Next, the returning-home direction estimation unit 312 estimates the returning-home direction when the user uses the vehicle 50 to return home from this visited facility.
Here, the returning-home direction estimation unit 312 can estimate the returning-home direction by referring to the parking information database 322, for example. Specifically, the returning-home direction estimation unit 312 compares the departure position in the parking information database 322 with the position of the facility included in the map information 321 (or the position of the parking lot associated with the facility). By this, the return direction is estimated.
This estimation is performed based on the idea that the user of the vehicle 50 will return to the same position as the starting position. The returning-home direction estimation unit 312 estimates that the returning home direction is the southeast direction, for example, when the departure position is a southeast direction from the facility position.

Further, the return-home direction estimation unit 312 may further consider the road information included in the map information 321 to estimate the return-home direction. For example, when the departure position is in the southeast direction of the facility position and the main road for moving in the southeast direction is located on the east side of the facility as described above, It is also possible to estimate that the eastward direction to join the main road is the return home direction. Alternatively, for example, when the bridge to cross to move in the southeast direction is located on the north side, the north direction to cross the bridge may be estimated to be the return home direction.
When the return-home direction estimation unit 312 estimates the return-home direction, it updates the “return-home direction” in the parking information database 322.

The recommended parking position calculation unit 313 calculates the recommended parking position based on the result of the return-home direction estimation performed by the return-home direction estimation unit 312. Here, the recommended parking position is calculated so that the vehicle 50 newly parked in the parking lot of the facility and the vehicle 50 in the same returning direction are dispersed, as described above.

As an example, a case where the vehicle 50A is newly parked in the facility A will be described as an example. In this case, the recommended parking position calculation unit 313 refers to the “visiting facility” and the “returning direction” in the parking information database 322, is the vehicle 50 that is visiting this facility A, and has the same returning direction as the vehicle 50A. All the vehicles 50 that are Then, the recommended parking position calculation unit 313 specifies the parking position of each of the visiting vehicles 50 thus extracted.

Then, the recommended parking position calculation unit 313 calculates the recommended parking position of the vehicle 50A so that the moving bodies in the same returning direction are dispersed. Specifically, the recommended parking position of the vehicle 50A is calculated such that the parking position of each of the visiting vehicles 50 having the same returning direction as the vehicle 50A and the parking position of the newly parked vehicle 50A are dispersed. To do. As a result, it is possible to prevent the vehicles 50 in the same returning direction from concentrating in the same parking area and parking at a specific doorway when returning home.

Calculation of the recommended parking position by the recommended parking position calculation unit 313 and its effect will be described with reference to FIG. FIG. 6 is a schematic view of a facility to be analyzed and a bird's-eye view of a parking lot and the like attached to the facility. In FIG. 6, a facility 71 to be analyzed, a plurality of parking areas (first area parking lot 72, second area parking lot 74, and third area parking lot 76) attached to the facility 71, and a plurality of these parking areas. A plurality of doorways (first doorway 73, second doorway 75, and third doorway 77) corresponding to the parking area of FIG. Further, it is assumed that there are a plurality of vehicles 50 whose return direction 78 is the return direction.

In this case, first consider a case where the user arbitrarily parks without using the present embodiment. In this case, each vehicle 50 in the returning direction 78 (that is, the vehicle 50 visiting from the direction opposite to the returning direction 78) may be concentrated and parked in the first area parking lot 72 which can be entered only by turning left. is assumed. In this case, when returning home, it is assumed that the first entrance/exit 73 is congested by the vehicle 50 that makes a right turn merge to move from the first entrance/exit 73 in the return home direction 78.

Therefore, in the present embodiment, the recommended parking position calculation unit 313 calculates the recommended parking position as described above. As a result, when the vehicle 50 parked in the first area parking lot 72 exists, the second area parking lot 74 and the third area parking lot 76 can be calculated as the recommended parking positions. By notifying the user of the newly parked vehicle 50 of this recommended parking position, it can be expected that the newly parked vehicle 50 will be dispersed and parked in the second area parking lot 74 or the third area parking lot 76. .. In this case, when returning home, the vehicle 50 parked in the second area parking lot 74 or the third area parking lot 76 returns home by using the second doorway 75 or the third doorway 77. This makes it possible to suppress congestion when returning home.

The notification unit 314 is a part that notifies the recommended parking position by transmitting the recommended parking position calculated as described above to the facility terminal 40. The notification unit 314 identifies the vehicle 50 that is about to newly park based on the “movement transition” in the parking information database 322. Then, the notification unit 314 transmits the recommended parking position calculated by the recommended parking position calculation unit 313 for the identified vehicle 50 to the facility terminal 40.

<Functional block of facility terminal 40>
Since the facility terminal 40 can be realized by a general personal computer, detailed description thereof will be omitted. As shown in FIG. 7, the facility terminal 40 includes at least a control unit 41, a storage unit 42, a communication unit 43, a display unit 44, and an input unit 45. The configurations of the respective units are the same as the configurations of the respective units in which the names of the vehicle-mounted navigation device 10 and the mobile terminal 20 are the same, for example.

The control unit 41 includes a recommended parking position acquisition unit 411 and a notification unit 412 as functional blocks. Further, in the drawing, the recommended parking position 421 is illustrated as the information stored in the storage unit 42. The recommended parking position 421 is a recommended parking position received by the recommended parking position acquisition unit 411 from the notification unit 314 of the parking information analysis device 30.

The recommended parking position acquisition unit 411 is a unit that the communication unit 43 receives from the notification unit 314 of the parking information analysis device 30 and acquires the recommended parking position. The recommended parking position acquisition unit 411 stores the acquired recommended parking position in the storage unit 42 as the recommended parking position 421.

The notification unit 412 is a part that notifies the user of the vehicle 50 who is about to newly park, of the recommended parking position stored as the recommended parking position 421.
The notification can be realized, for example, by displaying the recommended parking position on the display guide plate or outputting a voice indicating the recommended parking position. In this case, if a message such as "You can avoid congestion when returning home by parking in the recommended parking position." is recommended at the same time, the recommended parking position should be strongly recommended to the user. You can

Further, the notification may be directly given to the user of the vehicle 50. Alternatively, it may be performed for an employee of the facility (for example, a guide in a parking lot). In this case, the employee of the notified facility may notify the user of the vehicle 50 of the recommended parking position.
In addition, other information may be notified together with the recommended parking position in order to clarify which vehicle 50 the notification is. For example, the number of the license plate uniquely assigned to the vehicle 50 as the moving body ID or the telephone number of the mobile terminal 20 may be notified together with the recommended parking position. This allows the user of the vehicle 50 to easily understand which notification is the notification to the user.

<Operation of this embodiment>

If the ignition switch is still off, it is determined No in step S11 and the determination in step S11 is repeated. In this case, the position information transmitter 112 does not start the transmission.
On the other hand, when the ignition switch is turned on, it is determined Yes in step S11, and the process proceeds to step S12.

In step S12, the sensor unit 14 obtains the position information by measuring the position of the vehicle-mounted navigation device 10.

In step S13, the position information transmission unit 112 performs real-time transmission or burst transmission of the position information acquired in step S12 and the mobile body ID to the parking information analysis device 30 at a predetermined cycle.
In step S14, the movement transition update unit 311 and the returning-home direction estimation unit 312 update the parking information database 322 based on the position information and the like transmitted in step S13.

In step S15, the position information transmitting unit 112 determines whether to end the position information transmission. As described above, the transmission ends when the ignition switch of the vehicle 50a is turned off.
When the ignition switch of the vehicle 50a remains on, it is determined No in step S15, and steps S12, S13, and S14 are repeated again.

On the other hand, when the ignition switch of the vehicle 50a is turned off, it is determined Yes in step S15, and this processing ends.
By the operation described above, the parking information database 322 is updated based on the position information and the like.

Next, the operation of the mobile terminal 20 when updating the parking information database will be described. Regarding the mobile terminal 20, in the above description, the sensor unit 14 is replaced with the sensor unit 24, the position information transmitting unit 112 is replaced with the position information transmitting unit 212, and the criterion that becomes Yes in step S11 is "a vehicle such as an ignition switch. When the start switch of the vehicle 50b is turned on and the vehicle 50b and the mobile terminal 20 are paired", the reference that becomes Yes in step S15 is "the start switch of the vehicle 50b such as an ignition switch is turned off and the vehicle 50b and the portable terminal 20 are carried. If the pairing of the terminal 20 is released”, it may be replaced. Therefore, redundant description will be omitted.

Next, the operation during the parking information analysis process will be described with reference to the flowchart in FIG.
In step S21, the returning-home direction estimation unit 312 determines whether or not the visit of any of the vehicles 50 to the facility is detected. When the visit to the facility is not detected, it is determined No in step S21 and the determination is repeated.
On the other hand, when the visit to the facility is detected, it is determined Yes in step S22, and the process proceeds to step S22.

In step S22, the returning-home direction estimation unit 312 estimates the returning-home direction of the vehicle 50 that has visited the facility.
In step S23, the returning-home direction estimation unit 312 calculates the recommended parking position based on the returning-home direction and the like estimated in step S23.
In step S24, the notification unit 314 and the notification unit 412 notify the user of the vehicle 50 of the recommended parking position. As a result, this processing ends.

According to the present embodiment described above, it is possible to calculate the recommended parking position for suppressing congestion when returning home, based on the actual parking situation and the like. That is, according to the present embodiment, it is possible to perform analysis for suppressing congestion based on the actual parking situation and the like. In addition, the user who receives the notification can avoid the congestion when returning home by parking at the notified recommended parking position.

<First Modification>
In the above-described embodiment, the recommended parking position calculation unit 313 has extracted all the vehicles 50 that have the same returning direction as the newly parked vehicle 50. Then, the recommended parking position is calculated so that all the extracted vehicles 50 and the newly parked vehicles 50 are distributed in the same home direction.
Not limited to this, a part of the vehicles 50 is extracted from the vehicle 50 that has the same returning direction as the newly parked vehicle 50, and the part of the vehicles 50 and the newly parked vehicle 50 have the same returning direction. The recommended parking positions may be calculated so that the vehicles 50 are distributed. For example, the recommended parking positions are such that the newly parked vehicle 50 and the vehicle 50 in the same returning direction and the vehicles 50 in the same time zone when the parking starts are distributed in the same returning direction. May be calculated.
This means that if the facilities are the same, the staying time of each user will be the same length, so if the time when parking is started is in the same time period, the return time is also in the same time period. It is based.

Specifically, in the present modification, the latest predetermined time (for example, the latest one hour) is set as the same time zone from the time when the vehicle 50 is newly parked. In addition, the recommended parking position calculation unit 313 extracts only the vehicle 50 that is newly parked and has the same returning direction as the vehicle 50 and within the predetermined time when the parking start time is the latest. Then, the recommended parking position calculation unit 313 recommends the parking positions so that the vehicles 50 in the same predetermined returning time as the parking start time and the newly parked vehicles 50 are distributed in the same home direction. To calculate.
This makes it possible to suppress congestion between the vehicles 50 that are supposed to return home during the same time period. That is, congestion can be suppressed more efficiently.

Then, the notification unit 412 of the facility terminal 40 notifies the user of the vehicle 50 of this recommended parking position. Not limited to this, the notification may be realized by another method.

For example, the notification unit 314 may notify the vehicle-mounted navigation device 10 or the mobile terminal 20 of the recommended parking position. Then, the vehicle-mounted navigation device 10 or the mobile terminal 20 may notify the user of the vehicle 50 by displaying or voice-outputting the recommended parking position. In this case, the route guidance to the parking lot corresponding to the recommended parking position may be performed as part of the navigation (route guidance) performed by the vehicle-mounted navigation device 10 or the mobile terminal 20.
As a result, even if the facility terminal 40 cannot be installed, it is possible to notify the user of the recommended parking position.

<Other modifications>
As another modification, the vehicle-mounted navigation device 10 and the mobile terminal 20 may be realized by another device that does not have a route guidance function. That is, the route guidance function by the vehicle-mounted navigation device 10 or the mobile terminal 20 is not an essential configuration. In this case, the parking information analysis device 30 may further include a route guidance function, and the parking information analysis device 30 may perform route guidance by communicating with the vehicle-mounted navigation device 10 or the mobile terminal 20.
