The parking space information distribution system includes a plurality of vehicles 1 and a parking space information server 40 that can communicate with each vehicle 1.

  The vehicle 1 includes a parking space information collection device 10, a parking space information acquisition device 20, and an in-vehicle device 30 that operates in cooperation with the parking space information acquisition device 20. In FIG. 1, the parking space information collection device 10, the parking space information acquisition device 20, and the in-vehicle device 30 are shown only in the figure of one vehicle 1, but these are mounted on each of the plurality of vehicles 1. Yes. Moreover, the vehicle 1 which mounts only the parking space information collection apparatus 10 and the parking space information acquisition apparatus 20 and the vehicle-mounted apparatus 30 without mounting the parking space information collection apparatus 10 may exist. . In the present embodiment, it is assumed that the in-vehicle device 30 includes a car navigation device.

  The parking space information collection device 10 detects a parking space that appears around the host vehicle while the host vehicle is traveling, creates parking space information that is information about the parking space, and parks the created parking space information. Transmit to the space information server 40. The parking space information includes information on the position and size of the parking space, and vacancy information indicating whether or not the parking space is vacant. Hereinafter, the state in which the parking space is vacant is referred to as “empty state”, and the state in which other vehicles are parked in the parking space is referred to as “parked state”. In addition, in order to determine the validity period of the vacant information in the parking space information, information on the creation date and time may be included in the parking space information.

  The “parking space” referred to here is not limited to the parking section in the parking lot, but includes a wide range including all places where a vehicle can be parked, such as a roadside belt on a road.

  FIG. 2 is a block diagram illustrating a configuration of the parking space information collection device 10. As shown in FIG. 2, the parking space information collection device 10 includes a parking space detection unit 11, a parking space position measurement unit 12, a vehicle space size measurement unit 13, a parking space state determination unit 14, a parking availability determination unit 15, and a communication unit 16. It has.

  The parking space detection unit 11 detects a parking space around the host vehicle using a sonar sensor or a camera of the host vehicle. The parking space detection unit 11 analyzes the output of the sonar sensor and the image taken by the camera, searches for a space around the host vehicle, and the found space has a size and a height sufficient to park the vehicle. In addition, a condition such as whether the vehicle is parked away from the roadway and traffic is not hindered is determined, and a space that satisfies these conditions is detected as a parking space. Other than the sonar sensor and the camera may be used as the parking space detection means, and other than the above may be introduced as the parking space condition.

  The parking space position measurement unit 12 measures the position of the parking space detected by the parking space detection unit 11. The parking space position measuring unit 12 identifies the position of the host vehicle using, for example, a GPS receiver, a gyro sensor, or an acceleration sensor of the host vehicle, and further analyzes the output of the sonar sensor and the image taken by the camera. The position of the parking space can be measured by obtaining the relative position of the parking space with respect to the vehicle. The method for measuring the position of the parking space is not limited to the above method, and any sensor or other device may be used.

  The vehicle space size measurement unit 13 measures the size of the parking space detected by the parking space detection unit 11. The size of the parking space can be obtained, for example, by analyzing the output of the sonar sensor or an image taken by the camera.

  The parking space state determination unit 14 determines whether the parking space detected by the parking space detection unit 11 is an empty state or a parked state. This determination can also be made, for example, by analyzing the output of the sonar sensor or an image taken by the camera. The determination result by the parking space state determination unit 14 becomes vacant information of the parking space.

  The parking permission determination unit 15 determines whether the parking space detected by the parking space detection unit 11 is in a place where parking is permitted (hereinafter referred to as “parking permission place”). For example, the parking permission determination unit 15 uses information indicating a predetermined parking prohibited area to determine whether or not the detected parking space position is included in the parking prohibited area. Judge whether it is in place. The parking prohibition area information may be stored in the parking permission determination unit 15 or may be distributed from the parking space information server 40. Moreover, the information of a parking prohibition area may be contained in the map information which the car navigation apparatus as the vehicle-mounted apparatus 30 has. An arbitrary method other than the above method may be used as a method for determining whether or not the parking space is in the parking permission place.

  The communication unit 16 uses the parking space position measuring unit 12, the vehicle space size measuring unit 13, and the parking space state determining unit to determine the position, size, and vacancy information of the parking space that is determined to be in the parking permitted place by the parking permission determination unit 15. 14, the parking space information including such information is constructed and transmitted to the parking space information server 40. The parking space information transmitted from the communication unit 16 of the parking space information collection device 10 is received and stored in the parking space information server 40.

  The communication between the communication unit 16 and the parking space information server 40 is performed using a module capable of communicating using, for example, LTE (Long Term Evolution) or 3G mobile Internet, or a wireless LAN (Local Area Network) module. . The communication unit 16 may transmit the parking space information to the parking space information server 40 via an external medium such as an SD card, a smartphone, or a personal computer.

  The parking space information acquisition device 20 operates in cooperation with the in-vehicle device 30 such as a car navigation device, and acquires the parking space information from the parking space information server 40 in response to a request from the in-vehicle device 30. FIG. 3 is a block diagram illustrating a configuration of the parking space information acquisition device 20. As shown in FIG. 3, the parking space information acquisition device 20 includes a destination information acquisition unit 21, a vehicle size storage unit 22, and a communication unit 23.

  When the user sets the destination of the host vehicle using the in-vehicle device 30 such as a car navigation device, the destination information acquisition unit 21 acquires the set location information of the destination from the in-vehicle device 30.

  The vehicle size storage unit 22 stores information on the size of the host vehicle. Information on the size of the host vehicle may be set in the vehicle size storage unit 22 in advance, or may be input by the user through the in-vehicle device 30.

  The communication unit 23 communicates with the parking space information server 40. Specifically, when the destination information acquisition unit 21 acquires the position information of the destination of the host vehicle, the communication unit 23 requests the parking space information server 40 to transmit the parking space information (“parking space”). "Information request signal" is transmitted, and the parking space information transmitted from the parking space information server 40 as a response is received. The parking space information request signal includes the position information of the destination of the host vehicle acquired by the destination information acquisition unit 21 and the size information of the host vehicle stored in the vehicle size storage unit 22. In addition, the parking space information received by the communication unit 23 from the parking space information server 40 is transmitted to the in-vehicle device 30.

  The communication method between the communication unit 23 of the parking space information acquisition device 20 and the parking space information server 40 may be the same as the communication method between the communication unit 16 of the parking space information collection device 10 and the parking space information server 40. Therefore, when one vehicle 1 includes both the parking space information collection device 10 and the parking space information acquisition device 20, the communication unit 16 of the parking space information collection device 10 and the communication of the parking space information acquisition device 20 The unit 23 may be configured to use the same communication module or external medium.

  The parking space information server 40 receives and stores the parking space information transmitted by the parking space information collection device 10 of each vehicle 1 and responds to a parking space information request signal from the parking space information acquisition device 20 of each vehicle 1. The stored parking space information is transmitted. Further, the parking space information server 40 may distribute information other than the parking space information (for example, information on the parking prohibited area) to the parking space information collection device 10 or the parking space information acquisition device 20.

  FIG. 4 is a block diagram showing the configuration of the parking space information server 40. As illustrated in FIG. 4, the parking space information server 40 includes a communication unit 41, a parking space information storage unit 42, and an information selection unit 43.

  The communication unit 41 communicates with the parking space information collection device 10 and the parking space information acquisition device 20 of the plurality of vehicles 1. That is, the communication unit 41 receives the parking space information transmitted by the parking space information collection device 10 of each vehicle 1 and the parking space information request signal transmitted by the parking space information acquisition device 20 of each vehicle 1. In addition, when the communication unit 41 receives the parking space information request signal, as a response thereto, the communication unit 41 displays the parking space information stored in the parking space information storage unit 42 as the parking space information of the transmission source of the parking space information request signal. It transmits to the acquisition device 20.

  The parking space information storage unit 42 stores the parking space information received from the parking space information collection device 10 by the communication unit 41. In addition, in order to determine the validity period of the vacant information of the parking space information, the parking space information storage unit 42 may add information on the reception date / time or registration date / time to the parking space information.

  The information selection unit 43 selects information to be transmitted to the parking space information acquisition device 20 from the parking space information stored in the parking space information storage unit 42. Specifically, the information selection unit 43 is located within a predetermined range from the destination based on the information on the position of the destination and the size of the vehicle included in the parking space information request signal, and the vehicle The parking space information of a parking space having a size that fits the size of the vehicle (a size that can fit the vehicle) is searched, and the found parking space information is selected. The “predetermined range from the destination” may be, for example, a range within a certain distance from the destination, or a range within a certain time from the destination.

  Next, the operation of the parking space information distribution system according to the present embodiment will be described. First, the operation of the parking space information collection device 10 and the parking space information server 40 when the parking space information collection device 10 detects a parking space while the vehicle 1 is traveling will be described. FIG. 5 is a flowchart showing the operation of the parking space information collection device 10, and FIG. 6 is a flowchart showing the operation of the parking space information server 40. The process of FIG. 5 is executed each time the parking space information collection device 10 detects parking space information, and the process of FIG. 6 is performed every time the parking space information server 40 receives parking space information from the parking space information collection device 10. To be executed.

  Referring to FIG. 5, when parking space detection unit 11 of parking space information collection device 10 detects a parking space (step S101), parking space position measurement unit 12 measures the position of the parking space and measures the vehicle space size. The unit 13 measures the size of the parking space, and the parking space state determination unit 14 determines whether or not the parking space is empty. Thereby, parking space information including the position, size, and vacancy information of the parking space is constructed (step S102).

  Moreover, the parking permission determination part 15 determines whether the said parking space exists in a parking permission place based on the position of the parking space which the parking space position measurement part 12 measured (step S103). When the said parking space exists in a parking permission location (it is YES at step S103), the communication part 16 transmits the parking space information constructed | assembled by step S102 to the parking space information server 40 (step S104). When the said parking space is not in a parking permission place (it is NO at step S103), the parking space information constructed | assembled by step S102 is discarded, without sending the parking space information server 40. FIG.

  With reference to FIG. 6, the communication part 41 of the parking space information server 40 receives the parking space information transmitted from the parking space information collection device 10 (step S201). The parking space information storage unit 42 stores the parking space information received by the communication unit 41. At this time, the parking space information storage unit 42 checks whether the parking space information is information on an unregistered parking space (step S202). If the parking space information is information on a registered parking space (NO in step S202), the existing parking space information is updated (step S203). If the parking space information is information on an unregistered parking space (YES in step S202), it is registered as information on a new parking space (step S204).

  Through the above processing, the parking space information of the parking space detected by the parking space information collection device 10 is stored in the parking space information acquisition device 20.

  Next, when the destination of the host vehicle is set in the in-vehicle device 30 such as a car navigation device, and the parking space information acquisition device 20 acquires the parking space information from the parking space information server 40, the parking space information acquisition device 20 and The operation of the parking space information server 40 will be described. FIG. 7 is a flowchart showing the operation of the parking space information acquisition device 20, and FIG. 8 is a flowchart showing the operation of the parking space information server 40. The process of FIG. 7 is executed each time the destination of the host vehicle is set in the in-vehicle device 30, and the process of FIG. 8 is received by the parking space information server 40 from the parking space information acquisition device 20. It is executed every time.

  Referring to FIG. 7, when the destination of the host vehicle is set in the in-vehicle device 30 such as a car navigation device, the destination information acquisition unit 21 acquires the position information of the destination (step S301). The communication unit 23 sends a parking space information request signal including the destination position acquired by the destination information acquisition unit 21 and the size information of the host vehicle stored in the vehicle size storage unit 22 to the parking space information server. 40 (step S302).

  8, the communication unit 41 of the parking space information server 40 receives the parking space information request signal transmitted from the parking space information acquisition device 20 (step S401). The information selection unit 43 is located in the vicinity of the destination indicated by the parking space information request signal from the parking space information stored in the parking space information storage unit 42, and the vehicle indicated by the parking space information request signal The parking space information of the parking space that satisfies the condition that the size fits is extracted (step S402).

  At this time, if no parking space information satisfying the conditions is found (NO in step S403), the communication unit 41 notifies the parking space information acquisition device 20 that there is no parking space information (step S404), and the processing is terminated. To do.

  Moving to FIG. 7, when the parking space information acquisition device 20 receives a notification that there is no parking space information from the parking space information server 40 (YES in step S303), the parking space information acquisition device 20 transmits the notification to the in-vehicle device 30 (step S304). . In this case, the in-vehicle device 30 performs processing such as notifying the user (mainly the driver of the own vehicle) that there is no parking space information using, for example, a display device or an audio output device.

  Returning to FIG. 8, when the information selection unit 43 finds the parking space information that satisfies the condition (YES in step S <b> 403), the information selection unit 43 confirms whether or not the current date and time is within the validity period of the vacant information of the parking space information. Then, it is determined whether or not the free space information of the parking space information is valid (step S405). The valid period of the vacant information in the parking space information is based on, for example, the creation date and time of the parking space information by the parking space information collection device 10, the reception date or registration date and time of the parking space information by the parking space information acquisition device 20, A certain period of time. The length of the period may be set to an arbitrary length by the administrator of the parking space information server 40. Thus, by providing an effective period for the vacant information of the parking space information, it is possible to eliminate vacant information with low reliability, and to improve the reliability of the parking space information distribution system.

  Here, the parking space information server 40 determines the validity period of the vacant information. However, the parking space information collection device 10 may determine when the parking space information is created, or the parking space information acquisition device 20 parks the parking space information. It may be determined when the space information is received. Alternatively, when the in-vehicle device 30 receives the parking space information from the parking space information acquisition device 20, the validity period of the vacant information may be determined.

  If the vacant information of the parking space information is valid (YES in step S405), the communication unit 41 transmits the parking space information including the vacant information to the parking space information acquisition device 20 (step S406). If the vacant information is not valid (NO in step S405), the communication unit 41 transmits the parking space information not including the vacant information to the parking space information acquisition device 20 (step S407).

  Moving to FIG. 7, when the communication unit 23 of the parking space information acquisition device 20 receives the parking space information transmitted from the parking space information server 40 (step S305), the communication unit 23 transmits the received parking space information to the in-vehicle device 30 ( Step S306).

  The in-vehicle device 30 can use the parking space information acquired from the parking space information acquisition device 20 as input information of the destination of the car navigation device. For example, when parking space information including vacant information is received, the car navigation device can present the position of the vacant parking space to the user as a destination candidate. In addition, when parking space information that does not include vacant information is received, it cannot be determined whether the parking space is vacant, but at least a position where the parking space exists can be presented to the user.

  Here, while the in-vehicle device 30 uses the parking space information, there is a possibility that the free space information of the parking space information stored in the parking space information server 40 is updated. Therefore, in the present embodiment, the parking space information acquisition device 20 transmits updated new parking space information from the parking space information server 40 until the use of the parking space information in the in-vehicle device 30 ends. (Steps S307 and S308).

  When the parking space information acquisition device 20 receives new parking space information (YES in step S308), the parking space information acquisition device 20 returns to step S306 and transmits the new parking space information to the in-vehicle device 30. When the use of the parking space information in the in-vehicle device 30 ends (YES in step S307), the parking space information acquisition device 20 notifies the parking space information server 40 to that effect (step S309) and ends the processing. .

  Referring to FIG. 8, after the parking space information server 40 transmits the parking space information in step S406 or S407, the parking space information is used while the parking space information is being used by the in-vehicle device 30 of the destination vehicle 1. It is continuously confirmed whether or not the empty information has been updated (steps S408 and S409). When the vacant information is updated for the parking space information in the middle of being used by the in-vehicle device 30 (YES in steps S408 and S409), the process returns to step S405, and the updated new parking space information is the parking space information acquisition device. 20 is transmitted. When the parking space information server 40 receives a notification from the in-vehicle device 30 that the use of the parking space information has ended (NO in step S409), the parking space information server 40 ends the monitoring of the empty information of the parking space information.

  As described above, in the parking space information distribution system according to the present invention, the parking space information collection device 10 of each vehicle 1 parks the parking space information of any parking space that appears around the vehicle while the vehicle is traveling. It can be transmitted to the space information server 40. Therefore, the parking space information server 40 accumulates information on any parking space regardless of the inside or outside of the parking lot. In addition, since the parking space information is distributed from the parking space information server 40 to the parking space information acquisition device 20 of each vehicle 1, the parking space information can be distributed to a large number of vehicles 1 in a wide range. In the vehicle 1 that has received the parking space information, the in-vehicle device 30 such as a car navigation device can use the parking space information received by the parking space information acquisition device 20. Moreover, since it is the structure which does not use the infrastructure of a parking lot, there also exists a merit which can restrain investment.
