The GPS unit 110 detects radio waves transmitted from a plurality of satellite communications (not shown), and acquires position information of the vehicles 1a and 1b (hereinafter collectively referred to as “vehicle 1”). The vehicle position information acquired by the GPS unit 110 is transmitted to the control device 140.
The shift position sensor 120 detects the shift position of the vehicle 1. The vehicle shift position information detected by the shift position sensor 120 is transmitted to the control device 140.

The vehicle travel history database 130 stores vehicle travel history information that is data related to the travel history of the vehicle 1. In the present embodiment, the control device 140 records information on the vehicle position and shift position acquired from the GPS unit 110 and the shift position sensor 120 in the vehicle travel history database 130 as vehicle travel history information. Further, the vehicle travel history information stored in the vehicle travel history database 130 is read and used by the control device 140 as needed.

Hereinafter, each configuration shown in FIG. 3 will be described. In the following description, description will be made using the configuration shown in FIG. 2 as appropriate.
As shown in FIG. 3, the parking lot information collection device 100 according to the present embodiment includes a processing start determination unit 101, a parking completion determination unit 102, a vehicle travel history information acquisition unit 103, a parking completion time calculation unit 104, A parking lot information transmission unit 105 is included.
The process start determination unit 101 determines whether to start the parking information collection process. Specifically, the parking completion determination unit 102 determines that the parking is completed during the previous parking lot information collection process, and is set in advance between the vehicle position of the vehicle 1 and the current vehicle position during the previous process. If there is no difference more than the distance (for example, 10 m or more), it is determined that the parking lot information collection process is not started, and otherwise, it is determined that the parking lot information collection process is started.

  In addition, in order to determine that “the parking completion determination unit 102 determines that the parking is completed during the previous parking lot information collection process”, for example, a parking completion flag is provided, and the parking completion determination unit 102 determines that the parking is complete. In this case, the parking completion flag is set to “1”, and when the processing start determination unit 101 determines that the processing is started, the parking completion flag may be set to “0”.

With such a mechanism, when parking of the vehicle 1 is completed, the parking lot information can be generated only once and transmitted to the server device 300 of the data center 2. In addition, the parking lot information collecting apparatus 100 does not perform useless processing and can suppress the processing amount.
The parking completion determination unit 102 determines whether the vehicle 1 has been parked. Specifically, the determination is performed based on the shift position information acquired by the shift position sensor 120. For example, when the shift position is a parking shift, it can be determined that parking has been completed.

  In addition, after it determines with the process start determination part 101 starting the collection process of parking lot information, until it determines with the parking completion determination part 102 having completed the parking of the vehicle 1, the vehicle travel history information acquisition part mentioned later At 103, the vehicle travel history information collection process is repeatedly executed. Further, when the parking completion determination unit 102 determines that the parking of the vehicle 1 has been completed, a parking completion time calculation process is executed in a parking completion time calculation unit 104 described later.

The vehicle travel history information acquisition unit 103 acquires vehicle travel history information including position information of the vehicle 1 and travel time information. In the present embodiment, the position information of the vehicle 1 is acquired by the GPS unit 110. The acquired position information and travel time information of the vehicle 1 are recorded and stored in the vehicle travel history database 130 as vehicle travel history information.
In the present embodiment, the vehicle travel history information acquisition unit 103 further acquires the shift position of the vehicle 1 as the vehicle travel history information. The shift position is acquired from the shift position sensor 120 and recorded in the vehicle travel history database 130 as vehicle travel history information together with position information and travel time information.

The vehicle travel history information acquisition process is repeatedly executed until the parking completion determination unit 102 determines that the vehicle 1 has been parked.
When the parking completion determination unit 102 determines that the parking of the vehicle 1 has been completed, the parking completion time calculation unit 104 completes parking based on the vehicle traveling history information before completion of parking acquired from the vehicle traveling history database 130. The parking completion time which is the time required until is calculated.

  Specifically, the parking completion time calculation unit 104 calculates the parking completion time as follows. That is, the parking completion time calculation unit 104 traces the position information of the vehicle 1 in the vehicle travel history information retroactively from the parking completion determination time. For example, the time when the vehicle 1 is located at a predetermined distance (for example, 100 m) from the parking position when parking is completed is set as the parking start time, and the time when parking is determined is set as the parking end time. And And the time from parking start time to parking end time is calculated as parking completion time.

  Further, the parking completion time calculation unit 104 may calculate the parking completion time with the time when the position of the vehicle 1 indicated by the position information is within the parking lot as the parking start time. Specifically, for example, the position information of the vehicle 1 included in the vehicle travel history information accumulated in the vehicle travel history database 130 is traced back to the past from the parking completion determination time. Then, while comparing the position information of the vehicle 1 with a map information database (not shown) provided in the vehicle 1, the position of the vehicle 1 is determined to be “outside the road” (that is, within the parking lot site). Is determined to be the parking start time.

When it is determined that the vehicle 1 is parked in the parking lot, the parking lot information transmission unit 105 calculates the vehicle ID for identifying the vehicle 1, the parking time (or the current time), the parking location information, and the parking completion time. The parking completion time calculated by the unit 104 is associated and transmitted to the server device 300.
In addition, transmission of parking lot information and the like is specifically transmitted to the server device 300 via the in-vehicle device communication device 150. At this time, the vehicle ID, the parking completion time, the parking lot position information, and the parking time (or current time) information only have to be associated with each other by giving a common identifier or the like, and are always transmitted to the server apparatus 300 at the same time.

If there is no difference more than the distance (for example, 10 m or more), it is determined that the parking lot information collection process is not started (step S101 = No), and the process is ended (END). In other cases, it is determined to start the parking lot information collection process (step S101 = Yes), and the process proceeds to step S102.

  In step S102, the parking completion determination unit 102 determines whether the vehicle 1 has been parked. Specifically, when the shift position information acquired by the shift position sensor 120 is a parking shift, it is determined that the parking is completed (step S102 = YES), and the process proceeds to step S104. Other than that, it determines with parking not being completed (step S102 = NO), and the vehicle travel history information acquisition part 103 acquires the vehicle travel history information containing the positional information on the vehicle 1, and travel time information, It records in the vehicle travel history database 130 (step S103) and ends (END).

On the other hand, in step S <b> 104, the parking completion time calculation unit 104 calculates the parking completion time based on the vehicle travel history information before completion of parking acquired from the vehicle travel history database 130. Specifically, the parking completion time calculation unit 104 calculates the parking completion time from the parking start time to the parking end time. For example, the time when the vehicle 1 is located in a place away from a parking position at the time of completion of parking by a predetermined distance (for example, 100 m) is set as the parking start time, and the time at the time of parking completion is set as the parking end time . And the difference from parking start time to parking end time is calculated as parking completion time.
Finally, the parking lot information transmission unit 105 receives the vehicle ID, the parking time (or the current time), the parking lot position information obtained from the GPS unit 110, and the parking completion time calculated by the parking completion time calculation unit 104 in step S104.

The determination unit 301 receives this information and, based on the contents, determines whether the data transmitted thereafter is parking lot information or the search condition for parking lot information (acquisition request information for parking lot related information). Determine if there is.

  In addition, whether the data is the parking lot information or the search condition in the parking lot information transmitted from the parking lot information collection device 100 or the header portion of the search condition transmitted from the parking lot related information presentation device 200. May be stored. The in-vehicle device information reception determination unit 301 determines whether the transmitted data is parking lot information or a search condition by analyzing a header portion of the received data. May be.

Based on the determination by the in-vehicle device information reception determination unit 301, what kind of processing is performed on the received data is determined. When the transmitted information is parking lot information, the parking lot information recording unit 303 described later records parking lot information. On the other hand, when the transmitted information is a search condition for parking lot information, a parking lot information search unit 304 described later searches for parking lot information.
The parking lot ID search unit 302 is expressed in latitude / longitude when the parking lot information recording unit 303 (to be described later) records parking lot information or when the parking lot information search unit 304 searches for parking lot information. The parking lot ID corresponding to the position information is obtained by searching the parking lot section database 320.

However, the parking lot position information included in the parking lot information and the planned parking position included in the search condition are converted into parking lot IDs in advance in the parking lot information collection device 100 and the parking lot related information presentation device 200. May be output to the server apparatus 300. In this case, the process in the parking lot ID search unit 302 is omitted. As a result, the processing load on the server device 300 is reduced.
The parking lot information recording unit 303 records the parking lot information transmitted from the vehicle 1 in the parking lot information database 310. The parking lot information includes information such as vehicle ID, parking time, parking completion time, parking lot location information, and parking lot ID searched by the parking lot ID search unit 302 from the parking lot location information.

  The parking lot information search unit 304 has a function of searching for parking lot information stored in the parking lot information database 310. Specifically, the parking lot information database 310 is searched and extracted for the parking lot information that matches the search condition received by the in-vehicle device information reception determination unit 301. Furthermore, for example, parking lot information that matches an arbitrary search condition is extracted from the parking lot information database 310. When searching by the parking lot information search unit 304, the parking lot ID output by the parking lot ID search unit 302 based on the planned parking position included in the search condition transmitted by the parking lot information collection device 100, the planned parking time, etc. Is specified as a search condition.

  For example, assume that a search condition such as “parking lot ID = 10101, scheduled parking time = 13: 00” is given. In this case, the parking lot information search unit 304 has the same parking lot ID and scheduled parking time from the parking lot information database 310, and the difference from the scheduled parking time in the search condition is within a preset time (for example, The parking lot information of the parking time that is within 30 minutes (12:30 to 13:30) is extracted.

The average parking completion time calculation unit 305 calculates an average value of the parking completion times included in the parking lot information extracted by the parking lot information search unit 304. Specifically, the average value of the parking completion time in each parking lot is calculated by dividing the parking completion time of the parking lot information extracted by the parking lot information search unit 304 by the number of the extracted parking lot information.
When the information presentation type received by the in-vehicle device information reception determination unit 301 is “parking completion scheduled time presentation mode”, the parking completion scheduled time estimation unit 306 uses the search condition received by the in-vehicle device information reception determination unit 301.

  When the information presentation type received by the in-vehicle device information reception determination unit 301 is the “recommended arrival time presentation mode”, the recommended arrival time calculation unit 307 performs parking within a predetermined time in the parking lot at the planned parking position. In order to complete the process, a recommended arrival time recommended as a time to arrive at the planned parking position is calculated. That is, if the driver arrives at the parking lot at the recommended arrival time, it is assumed that the parking can be completed within a predetermined time.

  Specifically, the recommended arrival time is calculated as follows. For example, the estimated arrival time (that is, the scheduled parking time) is sequentially input to the parking lot information search unit 304 as a search condition while shifting to a later time in a predetermined time unit (for example, 30 minutes). . As a result, the estimated arrival time when the average parking completion time calculated by the average parking completion time calculation unit 305 is within a predetermined time (for example, within 10 minutes) is output as the recommended arrival time.

The recommended arrival time calculation unit 307 may calculate the recommended arrival time when the average parking completion time calculated by the average parking completion time calculation unit 305 is equal to or longer than a predetermined time. As a result, the driver can know the arrival time at which parking is possible without taking time.
The surrounding parking lot search unit 308 extracts, from the parking lot information database 310, a parking lot with a specific parking lot ID and a surrounding parking lot that is a parking lot within a predetermined distance. Moreover, the distance between the position of the parking lot of specific ID and the position of a surrounding parking lot is calculated.

When the information presentation type received by the in-vehicle device information reception determination unit 301 is “recommended alternative parking lot presentation mode”, the recommended alternative parking lot search unit 309 may complete parking within a predetermined time. Search for recommended alternative parking spaces that are possible parking spaces.
Specifically, the search for the recommended alternative parking lot is performed as follows. For example, first, the recommended alternative parking lot search unit 309 inputs the parking lot ID corresponding to the planned parking position included in the search condition transmitted by the parking lot related information presentation device 200 to the surrounding parking lot search unit 308. . And the surrounding parking lot which is within a predetermined distance (for example, within a radius of 100 m) from the parking lot which matches this parking lot ID is searched. Then, the extracted parking lot IDs of the surrounding parking lots are input to the parking lot information search unit 304 as search conditions in the order of distance from the planned parking position. In addition, the average parking completion time calculation unit 305 calculates an average parking completion time for the search result. By repeating this, the recommended alternative parking lot search unit 309 outputs a parking lot when the calculated average parking completion time is within a predetermined time as a recommended alternative parking lot.

Further, the recommended alternative parking lot search unit 309 searches for the recommended alternative parking lot when the average parking completion time calculated by the average parking completion time calculation unit 305 is equal to or longer than a predetermined time. Good. As a result, the driver can know a parking lot that is close to the planned parking position and can be parked without taking time.
The parking lot related information output unit 311 outputs different information depending on the information presentation type included in the search condition received by the in-vehicle device information reception determination unit 301. When the information presentation type is “parking completion scheduled time presentation mode”, the parking completion scheduled time estimated by the parking completion scheduled time estimation unit 306 is output. When the information presentation type is “recommended arrival time presentation mode”, the recommended arrival time calculated by the recommended arrival time calculation unit 307 is output. When the information presentation type is “recommended alternative parking lot presentation mode”, the recommended alternative parking lot extracted by the recommended alternative parking lot search unit 309 is output.
These pieces of information are output via the data center communication device 340.
