  In a conventional system that provides information on empty parking spaces confirmed by sensors and cameras at the entrance of a parking lot, etc., the driver of the car actually has a free space that can be parked in any location. It is difficult to determine if there is. In addition, a system for guiding a route to an empty parking space in a parking lot has been proposed. However, since this is a guidance that does not consider vehicles passing through the parking lot, it is expected that a vehicle or the like that does not follow the guidance will park first, so there is a possibility that it will not necessarily provide effective information. is there.

  Accordingly, an object of the present invention is to provide a parking lot information providing system capable of providing effective parking lot information in consideration of a vehicle passing in the parking lot.

  An aspect of the present invention is a parking lot information providing system that executes a route search to a parking position candidate in consideration of a vehicle passing through a parking lot and provides recommended parking position information selected based on the route.

  A parking lot information providing system according to an aspect of the present invention includes a passage side sensor means for detecting a vehicle traveling in a passage in a parking lot, and a parking position side sensor for detecting a vehicle parked at a parking position in the parking lot. A parking space which is an empty parking space in the parking lot based on the detection result of the means, the acquisition means for setting the parking position in the parking lot, and the detection result of the parking position side sensor means and the setting information. A parking position candidate selecting means for selecting a position candidate; a means for generating all route information indicating a route along which the vehicle travels to the parking position candidate based on the detection result of the passage-side sensor means and the parking position candidate; Recommendation indicating the recommended parking position selected from the parking position candidates based on the determined route information, determining route information indicating the minimum value of the cost in the entire route information A configuration in which a recommended parking position selection means for providing vehicle position information.

  According to the present invention, it is possible to provide effective parking information that takes into account vehicles passing in the parking lot in particular, so that it is possible to reduce the time required for parking and to reduce unnecessary empty space. Management can be realized.

  Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a main part of the parking lot information providing system according to the present embodiment.

  The information providing system in the parking lot is roughly divided into the components in the parking lot having the passage side sensor 1, the parking position side sensor 2, the parking lot data processing unit (local system) 3 and the parking lot side communication facility 16, and the central processing unit ( Central system) 4.

  As shown in FIG. 2, a parking lot side communication facility 16 is arranged in the vicinity of the doorway in the parking lot. A plurality of passage side sensors 1 are arranged at regular intervals in the passage in the parking lot. The passage-side sensor 1 detects an automobile traveling in the passage and transmits the detection signal to the local system 3. A parking position side sensor 2 is arranged in each designated parking area (parking position) in the parking lot. The parking position side sensor 2 detects a car parked in each parking area and transmits the detection signal to the local system 3.

  Here, as the passage side sensor 1 and the parking position side sensor 2, for example, a vehicle detector used in a road traffic control system or the like is used. The vehicle detector includes an ultrasonic type and a loop coil type, and can measure the traffic volume, time occupancy (occupancy), and travel speed of an automobile. Thereby, the passage side sensor 1 can measure that the vehicle traveled through the passage in the parking lot. The parking position side sensor 2 can measure that the automobile is parked at the parking position.

  Further, by using a DSRC (dedicated short range communication) facility as the passage-side sensor 1, it is possible to measure that a vehicle equipped with the DSRC facility has traveled along the passage. Similarly, by using the DSRC equipment as the parking position side sensor 2, it can be measured that the vehicle equipped with the DSRC equipment is parked at the parking position. However, as a matter of course, it cannot be applied to a vehicle outside the DSRC communication range or not equipped with a DSRC facility.

  Furthermore, by using a monitoring camera as the passage-side sensor 1 and analyzing a moving image of the monitoring camera using an image analysis technique such as background difference, it is possible to measure that the automobile is traveling in the passage. Similarly, by using a surveillance camera as the parking position side sensor 2, it is possible to measure that the automobile is parked at the parking position. However, it is necessary to install the surveillance camera in a place where no blind spot occurs.

  The local system (parking lot data processing unit) 3 executes data processing such as receiving detection results (measured values) from the passage side sensor 1 and the parking position side sensor 2 and converting them into digital data. The local system 3 collects each detection result subjected to data processing and transmits it to the central system (central processing unit) 4.

  The central system 4 includes a parking lot data management unit 5, a parking lot information database (parking lot data DB) 6, a parking lot setting information database (parking lot setting data DB) 7, a parking position situation grasping unit 8, A parking lot passage situation grasping unit 9, a parking lot setting data extracting unit 10, a parking position candidate selecting unit 11, a route searching unit 12, a recommended parking position selecting unit 13, a providing information creating unit 14, and a providing information transmitting unit 15. As will be described later, the central system 4 recommends the recommended parking position information to be provided to the vehicle user (driver) based on the data indicating the situation of the parking lot passage and the parking position transmitted from the local system 3. It is generated by the position selection unit 13. The central system 4 transmits the recommended parking position information generated from the provided information transmission unit 15 to the parking lot side communication facility 16.

  The parking lot side communication facility 16 includes a parking lot side communication infrastructure provision information creation unit (hereinafter abbreviated as provision information creation unit) 17, and a parking lot side communication infrastructure provision information transmission unit (hereinafter referred to as provision information transmission unit). (Omitted) 18. The parking lot side communication facility 16 creates provision information using the recommended parking position information transmitted from the central system 4 and transmits the provision information to the vehicle-mounted device 19 mounted on the automobile (vehicle) 22 by DSRC. The in-vehicle device 19 includes an in-vehicle device provision information receiving unit (hereinafter abbreviated as a receiving unit) 20 and an in-vehicle device information providing unit 21.

(System operation)
Hereinafter, the operation of the system of the present embodiment will be described with reference to FIGS.

  In the present embodiment, as shown in FIG. 2, a situation is assumed immediately before the automobile 22 driven by the user (driver) enters the parking lot from the entrance / exit of the parking lot. This system provides recommended parking position information by DSRC wireless communication to the vehicle-mounted device 19 of the automobile 22 from the parking lot side communication facility 16 arranged in the vicinity of the entrance / exit. The user can check the recommended parking position in the parking lot on the display included in the in-vehicle information providing unit 21 of the on-vehicle device 19. Details will be described below.

  First, the central system 4 always receives the data transmitted from the local system 3, and the driving situation of the car in the aisle in the parking lot (especially the number of vehicles in each aisle) and the situation of the parking position (empty space). ) In a time series. Specifically, the parking lot data management unit 5 accumulates the data transmitted from the local system 3 in the parking lot data DB 6 and performs data management for extracting the requested data from the parking lot data DB 6 as necessary. .

  Here, parking lot configuration information (parking position layout information) for identifying a parking position in the parking lot is stored in the parking lot setting data DB 7. The parking lot data management unit 5 acquires the parking lot configuration information from the parking lot setting data DB 7, and manages the parking position information where the vehicle is currently parked from the data transmitted from the local system 3.

  Hereinafter, the operation of the central system 4 will be described with reference to the flowchart of FIG. 5 when the parking lot is relatively small.

  Based on the parking lot configuration information and the parking position information acquired from the parking lot data management unit 5, the parking lot position situation grasping unit 8 sets information indicating the parking position where the vehicle is not parked in the parking lot (sets the parking position). Setting information), that is, an available parking space that can be parked is extracted (step S1). Using the information indicating this empty parking space, the parking position candidate selection unit 11 selects the current parking position candidate and outputs the parking position candidate information to the route search unit 12.

  Here, the parking position candidate selection unit 11 preferentially selects, for example, parking positions that are relatively close to the entrance / exit and parking positions that are included in an area with a lot of free parking spaces as candidates. In addition, when the absolute number of parking positions that are empty parking spaces is small, the parking position candidate selecting unit 11 selects all the empty parking spaces as parking position candidates.

  On the other hand, the parking lot passage state grasping unit 9 grasps the traveling state (vehicle traffic state) of the automobile in the passage in the parking lot based on the information from the parking lot data management unit 5, and generates information indicating it. Specifically, the parking lot passage condition grasping unit 9 creates information indicating how many vehicles are passing for each passage in the parking lot. Here, for example, when an ultrasonic vehicle sensor is used as the passage-side sensor 1, the vehicle detector is installed at the start point and the end point of the straight passage. Basically, since it can be assumed that there is no overtaking in the passage in the parking lot, it is possible to estimate how many vehicles are traveling between the start point and the end point by counting the number of passing vehicles.

  Next, the route search unit 12 uses the information obtained by the parking position candidate selection unit 11 and the parking lot passage state grasping unit 9 to execute a route search process for selecting a recommended parking position, as will be described later. To do. Specifically, the route search unit 12 is a route candidate from the target vehicle position (the position of the automobile 22 shown in FIG. 2) such as the doorway to the parking position candidate (empty parking space) selected by the parking position candidate selection unit 11. Is extracted (step S2).

  As shown in FIG. 3, the route information used for the route search is expressed by a node 30 and a link 31, and is stored in the parking lot setting data DB 7 in advance. The path information includes the number of the link 31 connected to the position of the node as information of the node 30, and the number of the node 30 to which the link is connected as information of the link 31. The route information is information indicating a route from the entrance to all parking positions. In FIG. 3, a parking position 32 indicates a parking position candidate that is an empty parking space at the present time. The route search unit 12 extracts and uses route information from the parking lot setting data DB 7 via the parking lot setting data extraction unit 10 as necessary.

  Next, in order to reflect the influence of the vehicle traveling on the route for all route information indicating the extracted route candidates, the route search unit 12 from the parking lot passage state grasping unit 9 for each passage in the parking lot, Information indicating the number of traveling vehicles is acquired (step S3). Specifically, the route search unit 12 reflects the cost (cost information described later) used to evaluate the priority of the route during the route search. For example, when the number of traveling vehicles on the route candidate is large, the score is higher than when the number of traveling vehicles is small, so that the possibility of being selected as a recommended parking position candidate is reduced.

  Here, in addition to the method of extracting a route using general route search software, the route search unit 12 includes the above-described costs (in other words, the routes corresponding to all routes up to all parking positions and the components of the route). , Merit) score is registered as cost information, and all route information to each empty parking space is extracted using this cost information. The score is an index that is evaluated based on, for example, the travel distance of the vehicle, the ease of travel, the number of direction changes, and the like, and is a value that increases the burden on the user of the automobile 22 as the numerical value increases. In short, the cost can be converted into a travel time for traveling from the doorway to the parking position. Therefore, the score indicating the cost increases as the traveling time increases.

  The route search unit 12 uses the acquired information to calculate the cost for all route information of all vacant parking spaces and create cost information (step S4). That is, for all route information, the total cost in each route information (information indicating the route from the position of the symmetric vehicle 22 to each parking candidate position) is calculated to generate cost information. As shown in FIG. 4, the cost information is table information including costs corresponding to each route (1, 2, 3...) And parking candidate positions (parking spaces 1, 2, 3,...). The lower the priority, the higher the priority to be selected.

  In short, the route search unit 12 searches for a route that minimizes these costs, for example, using the travel time as a cost. Therefore, since a large value is used as the cost, when there is a vehicle in the passage, a positive value is added so that the link is not easily selected, and a larger value may be added as the number of vehicles increases. Furthermore, not only the link where the vehicle exists, but also the link where the vehicle may travel from now on, the cost can be affected at a lower level than the link so that a more accurate route search can be performed. I can expect.

  Next, the recommended parking position selection unit 13 uses the cost information created by the route search unit 12 to select a recommended parking position corresponding to the route with the highest priority candidate, and provides the recommended parking position information to provide information It outputs to the part 14 (step S5). Specifically, from the cost information shown in FIG. 4, the recommended parking position selection unit 13 sets a route indicating an excellent cost with a low score among the extracted routes, for example, a route 1 with a score of 10 as a top priority candidate, The corresponding parking space 2 is selected as a recommended parking position.

  As a next plan, for example, a route 3 with a score of 15 is set as a candidate, and the corresponding parking space 1 is selected as a recommended parking position. As the cost information, the distance between the first candidate and the second candidate is calculated. For example, as a next plan, a parking space 2 corresponding to the route 2 is selected as a recommended parking position, and a plurality of candidates are close to each other. The priority order may be changed by the third candidate.

  The provision information creation unit 14 converts (creates) the recommended parking position information selected by the recommended parking position selection unit 13 into information in a format provided to the user of the automobile 22. The provided information transmitting unit 15 transmits the provided information created by the provided information creating unit 14 to the parking lot side communication facility 16. In the parking lot side communication facility 16, the provision information creation unit 17 creates provision information for transmitting the recommended parking position information transmitted from the central system 4 to the vehicle-mounted device 19.

  The provision information transmission unit 18 transmits the provision information created by the provision information creation unit 17 to the vehicle-mounted device 19 mounted on the car 22 to be provided by DSRC. In the vehicle-mounted device 19, the receiving unit 20 receives the provision information by DSRC and transfers the information to the in-vehicle device information providing unit 21. The vehicle-mounted device information providing unit 21 displays the provided information on the display, and provides recommended parking position information to the user.

  FIG. 6 is a flowchart for explaining the operation of the central system 4 when the parking lot is relatively medium or large.

  The process from step S11 to S13 shown in FIG. 6 is the same as the process from step S1 to S3 in FIG. That is, the parking lot position situation grasping unit 8 extracts an available parking space that can be parked (step S11). The route search unit 12 includes all route information indicating route candidates from the target vehicle position such as the doorway (the position of the automobile 22 shown in FIG. 2) to the parking position candidate (empty parking space) selected by the parking position candidate selection unit 11. Is extracted (step S12).

  Further, the route search unit 12 travels from the parking lot passage state grasping unit 9 to each passage in the parking lot in order to reflect the influence of the vehicle traveling on the route for all route information indicating the extracted route candidates. Information indicating the number of vehicles to be acquired is acquired (step S13).

  Next, the route search unit 12 uses the acquired information to perform route search on all route information of all the empty parking spaces, and extracts several upper cases of each route as route candidates (step S14). ). That is, the route search unit 12 performs route search on all route information of each empty parking space, and extracts several cases with excellent cost, that is, low cost, as route candidates in each empty parking space. The extraction method is the same as in FIG.

  Next, the recommended parking position selection unit 13 uses the cost information created by the route search unit 12 to select a recommended parking position corresponding to the route with the highest priority candidate, and provides the recommended parking position information to provide information It outputs to the part 14 (step S15). That is, the recommended parking position selection unit 13 sets a route indicating an excellent cost (low cost) having a low score from the extracted route candidates in each empty parking space as the highest priority candidate, and sets the corresponding parking space 2 as the recommended parking position. Select as

  As described above, in the system of the present embodiment, the user (driver) of the automobile 22 recommends parking position information by DSRC wireless communication from the parking lot side communication facility 16 immediately before entering the parking lot from the parking lot entrance / exit. Is provided. If it is this embodiment, a suitable route according to the vehicle traffic situation of the passage in the parking lot and the situation of the parking position is searched, and the recommended parking position that is estimated to take the least time to park for the user Information (in other words, low-cost candidate parking position information) can be provided. Thereby, the user can park without stress, and can save useless time searching for a parking position in the parking lot. For this reason, the effect which can ease congestion in a parking lot is acquired.

  Here, the feature of this embodiment is not a method of guiding the user to an empty parking space but a method of providing information on an empty parking space that is a low-cost parking candidate as recommended parking position information. Therefore, the actual parking position is ultimately left to the user's judgment. Thereby, even if it recommends the parking position of the minimum cost as a system, the user can select the recommended parking position of the next plan for another reason.

  When DSRC is used as the aisle-side sensor 1, road-to-vehicle communication is possible with the DSRC. Therefore, the latest information (not only on the entrance / exit of the parking lot) but also on the vehicle-mounted device 19 of the automobile 22 in the passage ( (Recommended parking position information) can be provided. Moreover, when using a monitoring camera as the parking position side sensor 2, you may provide the image image | photographed with the monitoring camera as recommended parking position information with respect to the onboard equipment 19. FIG.

  Specifically, as shown in FIG. 7, multiple case information (here, screen information for three cases) indicating a plurality of recommended parking positions may be provided on the monitor (display) of the vehicle-mounted device 19. However, the number of cases to be provided is limited based on the size of the monitor screen of the vehicle-mounted device 19 and the like. Moreover, when there is no surveillance camera, as shown in FIG. 8, the method of providing the information which made the plan view which looked at the parking lot from the top into the vehicle equipment 19 may be used. In this case, as shown in FIG. 8, it is desirable to distinguish and display the first candidate 80 and the second candidate 81 as recommended parking positions. Furthermore, information may be provided by voice using a speaker of the vehicle-mounted device 19.
