Description

  The present invention relates to a target parking spot setting system and a target parking spot setting program.

  A technique for determining whether a parking lot is full or empty based on the behavior of a vehicle in the parking lot is known (see Patent Document 1). In patent document 1, it is determined that the parking lot is full when the time required for parking in the parking lot and the distance from the parked position to the pedestrian entrance of the parking lot are long.

JP2013-210706A

However, even if the parking lot determined to be empty by the determination method of Patent Document 1 is recommended, there is a problem that the user does not necessarily want to park in the empty parking lot. That is, in Patent Document 1, there is a problem that a parking lot that the user does not want to park is recommended even if the vehicle is empty.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of recommending or targeting a parking spot that a user wants to park.

  In order to achieve the above object, a target parking spot setting system of the present invention is a target parking spot setting system for setting a target parking spot that is a recommended or parking target parking spot. The passing frequency acquisition unit that acquires the passing frequency, which is the frequency of passing through, for each parking spot, and the second parking spot whose passing frequency is lower than the first parking spot are given priority over the first parking spot. A target parking spot setting unit that is set as a parking spot.

  In order to achieve the above object, the target parking spot setting program of the present invention is a target parking spot setting program that causes a computer to function as a target parking spot setting system that sets a target parking spot that is a recommended or parking target parking spot. A passing frequency acquisition unit that acquires a passing frequency, which is a frequency at which a computer passes through a computer even though it is an empty vehicle, for each parking spot, a second parking spot whose passing frequency is smaller than the first parking spot Is made to function as a target parking spot setting unit that sets the target parking spot in preference to the first parking spot.

  In the present invention configured as described above, a parking spot with a low passing frequency, which is a frequency that a vehicle passes through even though it is an empty car, is estimated to be a parking spot where many users want to park, that is, a parking spot with high popularity. it can. On the other hand, a parking spot with a high passing frequency can be estimated as a parking spot where many users do not want to park, that is, a parking spot with low popularity. Therefore, by setting a parking spot with a lower passing frequency with priority as a target parking spot, a parking spot that is highly popular and that many users want to park can be set as the target parking spot.

It is a table | surface which shows probe data and parking location DB. 4A is a flowchart of an empty vehicle state recognition process, FIG. 4B is a flowchart of a passing frequency update process, and FIG. 4C is a flowchart of a target parking lot setting process.

Here, embodiments of the present invention will be described in the following order.

(1) Configuration of the target parking spot setting system:
FIG. 1 is a block diagram showing a configuration of a target parking spot setting system 10 according to an embodiment of the present invention. The target parking spot setting system 10 is a server that can communicate with the vehicle 100 and the weather server 200. The weather server 200 is a server that transmits weather information indicating the weather at the current time in each region and the weather predicted at the future time to the target parking spot setting system 10.

  The vehicle 100 includes a positioning unit 110, a user I / F unit 120, an in-vehicle computer 130, and a camera 140, and records parking frame information 150 on a recording medium (not shown). The positioning unit 110 includes various sensors for measuring the current location of the vehicle, and may include, for example, a GNSS receiving unit, a vehicle speed sensor, a gyro sensor, and a camera. The positioning unit 110 outputs information obtained by these sensors to the in-vehicle computer 130.

  The user I / F unit 120 includes an output device such as a display and a speaker, and an input device such as a touch sensor and a mechanical switch. The user I / F unit 120 outputs input information indicating the content of the operation performed on the input device to the in-vehicle computer 130. The in-vehicle computer 130 outputs output information to be output from the output device to the user I / F unit 120.

  The in-vehicle computer 130 may be an in-vehicle device additionally mounted on the vehicle 100 or may be a computer incorporated in the vehicle 100 from the beginning. The in-vehicle computer 130 specifies the current location of the vehicle based on the information output from the positioning unit 110. The in-vehicle computer 130 may specify the current location by performing map matching based on the map information.

  The camera 140 is a camera that captures a forward landscape image from the vehicle 100. The central optical axis of the camera 140 faces the front front direction of the vehicle 100. The parking frame information 150 indicates the arrangement of the parking frame in the parking lot, the shape of the frame line forming the parking frame, and the like. The in-vehicle computer 130 recognizes the parked vehicle and the frame line of the parking frame by performing image recognition processing of the landscape image captured by the camera 140. Then, the in-vehicle computer 130 recognizes an empty vehicle state of each parking frame indicated by the parking frame information 150 by the image recognition process of the landscape image. The in-vehicle computer 130 recognizes that the parking frame where the parked vehicle exists is full, and recognizes the parking frame where the parked vehicle does not exist as an empty vehicle.

  FIG. 2 is a plan view of the parking lot P. FIG. In the parking lot P, an entrance I, an exit O, and 60 parking frames T10 to T69 are arranged. Hereinafter, the parking frames T10 to T69 may be simply referred to as the parking frame T. The in-vehicle computer 130 determines whether or not the parking frames T <b> 10 to T <b> 69 are empty by performing image recognition processing on the landscape image captured by the vehicle 100 moving in the parking lot P. Image recognition processing is performed on landscape images captured at predetermined time intervals during movement in the parking lot P, thereby sequentially recognizing empty vehicle conditions of the parking frames T10 to T69 that are within the angle of view of the camera 140 during movement. Can continue.

  However, the parking frame T that does not exist in the vicinity of the moving route R of the vehicle 100 is not captured with a size that is outside the angle of view of the camera 140 or that allows image recognition processing. Therefore, it cannot be determined whether or not the parking frame T that does not exist in the vicinity of the movement route R of the vehicle 100 is full. The in-vehicle computer 130 determines that the vehicle 100 has not yet reached the parking frame T for which it was not possible to determine whether the vehicle is full. Moreover, the vehicle-mounted computer 130 acquires the parking frame T (parking frame T22 of FIG. 2) where the vehicle 100 parked.

  When the vehicle 100 completes parking, the in-vehicle computer 130 generates probe data indicating an empty vehicle status (parking, full, empty, unreachable) for each of the parking frames T in the parking lot P, and the target parking spot setting system 10 Send to. The probe data is transmitted every time the vehicle 100 is parked in any parking frame T in any parking lot P.

  When the vehicle 100 is parked in any parking frame T in the parking lot P, the in-vehicle computer 130 does not generate probe data until it enters the parking lot P next time. That is, probe data indicating an empty vehicle state recognized between the time when the vehicle 100 enters the parking lot P and the time when the vehicle 100 is parked at any parking frame T is generated. Probe data indicating the empty vehicle status recognized during the period from parking at 1 to leaving the parking lot P is not generated. Although not shown, probe data is transmitted from a large number of vehicles 100 to the target parking spot setting system 10.

  The in-vehicle computer 130 acquires the destination G based on the user's designation operation in the user I / F unit 120. The destination is specified from facilities registered in a facility DB (Database) 30b described later. The in-vehicle computer 130 transmits the parking spot request data indicating at least the identification code of the vehicle 100 and the destination to the target parking spot setting system 10.

  The target parking spot setting system 10 includes a control unit 20 and a recording medium 30. The control unit 20 includes a CPU, a RAM, a ROM, and the like, and executes a target parking spot setting program 21 stored in the recording medium 30 or the ROM.

  The recording medium 30 records a parking spot DB (Database) 30a and a facility DB 30b. The parking spot DB 30a is a database that records at least the position of the parking lot, the site, the name, and the number and arrangement of parking frames for each parking lot. The parking spot DB 30a includes passage frequency information 30a1 indicating the passage frequency for each parking frame provided in the parking lot. Details of the passing frequency will be described later. The facility DB 30b is a database that records at least the location and name of the facility for each facility.

  The target parking spot setting program 21 causes the target parking spot setting system 10 to realize a function of setting a target parking spot that is a recommended or parking target parking spot. The target parking spot setting program 21 includes a passage frequency acquisition module 21a and a target parking spot setting module 21b. The passing frequency acquisition module 21a and the target parking spot setting module 21b are program modules that cause the control unit 20 as a computer to function as a passing frequency acquisition part and a target parking spot setting part, respectively.

  With the function of the passage frequency acquisition module 21a, the control unit 20 acquires a passage frequency, which is a frequency that the vehicle 100 passes through even though it is an empty vehicle, for each parking spot. Specifically, the control unit 20 acquires the passing frequency for each parking frame T from the passing frequency information 30a1 by the function of the passing frequency acquisition module 21a. In the present embodiment, the parking spot is a parking frame T.

  Further, the control unit 20 acquires the passing frequency based on the empty vehicle situation of the parking frame T detected in the vehicle 100 by the function of the passing frequency acquisition module 21a. That is, by the function of the passage frequency acquisition module 21a, the control unit 20 updates the passage frequency of the passage frequency information 30a1 based on the probe data indicating the empty vehicle status of the parking frame T detected in the vehicle 100, and acquires the passage frequency. To do.

  FIG. 3 shows the probe data and passage frequency information 30a1 in the case of FIG. The control unit 20 adds an added value to the existing passing frequency for the parking frame T indicating that the probe data is an empty vehicle. In the present embodiment, the added value is any one of 0.2, 0.4, 0.6, and 0.8. Thereby, every time the vehicle 100 passes though it is an empty vehicle, the passing frequency can be added. That is, the passing frequency can be added to the parking frame T in which the user has recognized that it is an empty car but has not been parked. It is assumed that the parking frame T that can be determined whether the vehicle 140 is full or empty in the image recognition processing of the landscape image captured by the camera 140 can be determined as full or empty from the user's perspective.

  In the example of FIG. 2, an additional value is added to the passing frequencies of the parking frames T10 to T11, T19 to T20, T28, T39, T48 to T49, T59, and T65 to T69. In addition, the control part 20 may add an addition value only to the parking frame T which actually passed among the parking frames T which were empty vehicles, and within the fixed distance (for example, 5 m) from the moving route R of the vehicle 100. The added value may be added only to the parking frame T. Further, when the control unit 20 moves backward and parks in the parking frame T22, the control unit 20 may exclude a portion in front of the parking frame T22 from the movement route R. This is because the part of the moving route R ahead of the parked parking frame T22 has only progressed in preparation for parking, and has not passed through strictly.

  By the function of the passage frequency acquisition module 21a, the control unit 20 sets the added value of the passage frequency to be added to the parking frame T, which is an empty vehicle, to a larger value as the unreachable rate is higher. The unreached rate is a ratio obtained by dividing the unreachable number, which is the number of times probe data indicating unreached is received, by the total number of times the vehicle 100 (all vehicles) parked in the same parking lot P. . The total number of times the vehicle 100 has been parked is the total number of times probe data indicating that the vehicle 100 (all vehicles) has been parked in any parking frame T in the same parking lot P is received.

  The control unit 20 sets the addition value of the passing frequency when the unreached rate is equal to or higher than the first threshold value to 0.8, and the added value of the passing frequency when the unreached rate is less than the first threshold value and equal to or higher than the second threshold value. Is set to 0.6, the passing frequency addition value is set to 0.4 when the unreached rate is less than the second threshold and not less than the third threshold, and the passing frequency is set when the unreached rate is less than the third threshold Is set to 0.2. Note that 1> first threshold> second threshold> third threshold> 0.

  The unreached rate is a value that increases as the parking frame T is less likely to reach the vehicle 100. It is considered that the higher the unreached rate, the parking frame T has a higher probability that the user did not want to park in the first place and the vehicle 100 did not even approach. Therefore, by increasing the passing frequency addition value as the unreachable rate increases, the passing frequency of the parking frame T that the user did not want to park in the first place is likely to increase even if the number of times of passing is small. it can. Here, the passing frequency is a frequency of passing through the parking frame T even though the vehicle 100 before parking is an empty vehicle. This is because the probe data indicates an unoccupied vehicle situation recognized between the time when the vehicle 100 enters the parking lot P and the time when the vehicle 100 is parked at any of the parking frames T.

  In the above, the process in which the control unit 20 updates the passing frequency information 30a1 by the function of the passing frequency acquisition module 21a has been described. Next, the process which the control part 20 performs by the function of the passage frequency acquisition module 21a when the parking spot request data is received from the vehicle 100 will be described.

  When the parking spot request data is received from the vehicle 100, the control unit 20 searches the parking spot DB 30a for the nearest parking lot P to the destination G indicated by the parking spot request data by the function of the passage frequency acquisition module 21a. And the control part 20 acquires the passing frequency about each of the parking frames T in the parking lot P nearest to the destination G from the passing frequency information 30a1.

  By the function of the target parking spot setting module 21b, the control unit 20 sets the second parking spot whose passing frequency is lower than the first parking spot as a target parking spot with priority over the first parking spot. Specifically, the control unit 20 selects a parking lot whose passing frequency is less than or equal to N (N is a natural number) among the parking frames T of the currently empty vehicle, and sets the parking lot as the target parking frame (target parking spot). To do. In this embodiment, N = 2. The control unit 20 acquires a parking frame T indicating that the latest probe data is an empty vehicle as the parking frame T of the currently empty vehicle. In the example of FIGS. 3 and 2, the parking frames T10 and T11 are set as the target parking frames.

  With the function of the target parking spot setting module 21 b, the control unit 20 generates target parking frame data for causing the user I / F unit 120 of the vehicle 100 to output a list of target parking frames, and transmits the target parking frame data to the vehicle 100. As a result, a list of target parking frames is output at the user I / F unit 120 of the vehicle 100. As a result, the target parking frame is recommended to the user.

  In the present embodiment described above, the parking frame T with a low passing frequency, which is the frequency that the vehicle 100 passes through even though it is an empty vehicle, is a parking frame T that many users want to park, that is, a parking frame T with high popularity. Can be estimated. On the other hand, it can be estimated that the parking frame T with a high passing frequency is a parking frame T that many users do not want to park, that is, a parking frame T with low popularity. Therefore, by setting the parking frame T with a lower passing frequency as a target parking frame with priority, the parking frame T that has a high degree of popularity and that many users want to park can be set as the target parking frame.

  Moreover, since the control part 20 acquires a passing frequency based on the empty vehicle condition of the parking frame T detected in the vehicle 100, it can acquire the passing frequency per parking frame T with high accuracy. Furthermore, the passing frequency is a frequency of passing through the parking frame T even though the vehicle 100 before parking is an empty vehicle. That is, by not counting the frequency that the user's vehicle 100 that has already parked and has no intention to park passes, a highly reliable passing frequency can be obtained.

(2) Empty vehicle status recognition processing:
FIG. 4A is a flowchart of an empty vehicle state recognition process. The empty vehicle state recognition process is a process executed by the in-vehicle computer 130 of the vehicle 100 that has entered the parking lot P. First, the in-vehicle computer 130 determines whether or not the vehicle 100 has entered the parking lot P (step S100). That is, the in-vehicle computer 130 determines whether or not the vehicle 100 has entered from the outside to the inside of the site of any parking lot P indicated by the parking spot DB 30a.

  If it is not determined that the vehicle 100 has entered the parking lot P (step S100: N), the in-vehicle computer 130 waits until the vehicle 100 enters the parking lot P. On the other hand, when it determines with the vehicle 100 having entered into the parking lot P (step S100: Y), the vehicle-mounted computer 130 recognizes an empty vehicle condition (step S110). Next, the in-vehicle computer 130 determines whether or not the vehicle 100 is parked (step S120). For example, the in-vehicle computer 130 determines that the vehicle 100 is parked when the engine or the main power source of the vehicle 100 turns from ON to OFF.

  If it is not determined that the vehicle 100 is parked (step S120: N), the in-vehicle computer 130 returns to step S110. That is, the in-vehicle computer 130 continues to recognize the empty vehicle status of the parking frame T until the vehicle 100 is parked. On the other hand, when it determines with the vehicle 100 having parked (step S120: Y), the vehicle-mounted computer 130 transmits the probe data which show an empty vehicle condition for every parking frame T to the object parking spot setting system 10 (step S130). That is, the in-vehicle computer 130 generates probe data indicating an empty vehicle status (parking, full, empty, unreachable) for each of the parking frames T in the parking lot P, and transmits the probe data to the target parking spot setting system 10.

(3) Pass frequency update processing:
The passing frequency update process executed by the target parking spot setting system 10 will be described. FIG. 4B is a flowchart of the passage frequency update process. The passing frequency update process is a process executed by the control unit 20 of the target parking spot setting system 10 that has received the probe data from the vehicle 100. First, the control unit 20 determines whether probe data has been received by the function of the passage frequency acquisition module 21a (step S200).

  When it is not determined that probe data has been received (step S200: N), the control unit 20 waits until probe data is received by the function of the passage frequency acquisition module 21a. On the other hand, when it determines with having received probe data (step S200: Y), the control part 20 adds 1 to the unreachable frequency | count of the unreachable parking frame T by the function of the passage frequency acquisition module 21a (step S210). . That is, the control unit 20 adds 1 to the number of times the parking frame T has not reached because the vehicle 100 is not approaching and the empty vehicle status cannot be recognized.

  Next, the control part 20 updates the addition value of the passing frequency of the unreachable parking frame T by the function of the passing frequency acquisition module 21a (step S220). That is, the control unit 20 is a ratio obtained by dividing the unreachable number obtained by adding 1 in step S210 by the total number of times that the vehicle 100 (all vehicles) has parked in the same parking lot P (60 times in FIG. 3). Calculate the unreached rate. And the control part 20 updates the addition value of passage frequency according to the result of having compared the unreachable rate with the 1st-3rd threshold value. That is, the control unit 20 sets the added value of the passing frequency to be added according to one pass as the parking frame T having a higher unreachable rate.

  Next, by the function of the passage frequency acquisition module 21a, the control unit 20 adds an added value to the passage frequency of the empty vehicle parking frame T (step S230). That is, the control unit 20 adds the added value to the passing frequency of the parking frame T through which the vehicle 100 passes though it is an empty vehicle. Through the above processing, the target parking spot setting system 10 updates the passing frequency information 30a1 every time it receives probe data.

(4) Target parking lot setting process:
Next, the target parking spot setting process executed by the target parking spot setting system 10 will be described. The target parking spot setting process is a process executed when parking spot request data is received from the vehicle 100. First, the control part 20 acquires the parking lot P nearest to the destination G by the function of the object parking spot setting module 21b (step S300).

  Next, by the function of the passing frequency acquisition module 21a, the control unit 20 sets the parking frame T of the empty vehicle with the lowest passing frequency as the target parking frame (step S310). Specifically, first, the control unit 20 acquires the passing frequency for each of the parking frames T in the parking lot P nearest to the destination G from the passing frequency information 30a1. Further, the control unit 20 acquires the parking frame T of the currently empty vehicle based on the latest probe data received for the parking lot P nearest to the destination G. And the control part 20 sets the parking frame T with the low pass frequency as the object parking frame among the parking frames T of the currently empty vehicle.

  When the target parking frame is set as described above, the control unit 20 generates the target parking frame data by the function of the target parking spot setting module 21b (step S320). Next, the control part 20 transmits object parking frame data by the function of the object parking spot setting module 21b (step S330). The target parking frame data is data for causing the user I / F unit 120 of the vehicle 100 to output a list of target parking frames, and is data for recommending the target parking frame to the user. The vehicle 100 that is the transmission destination of the target parking frame data is the vehicle 100 associated with the identification code indicated by the parking spot request data.

(5) Other embodiments:
The passing frequency of the present invention may be acquired for each vehicle type of the vehicle 100 and for each driving skill level of the driver of the vehicle 100. For example, a database that defines the vehicle type and the driving skill level of the driver for each identification code of the vehicle 100 may be recorded on the recording medium 30 of the target parking spot setting system 10. Further, the passing frequency information 30a1 may be recorded for each combination of the vehicle type and the driving skill level. The vehicle type may be classified according to, for example, a vehicle body type, a vehicle body size, or a vehicle body weight. Further, the driving proficiency level may be acquired based on, for example, a history of driving operations in the past of the vehicle 100, a driver's age, driving history, or the like.

  In the above configuration, the control unit 20 receives the probe data indicating the identification code from the vehicle 100, and determines the passage frequency indicated by the passage frequency information 30a1 corresponding to the combination of the vehicle type and the driving skill level associated with the identification code. Update. In addition, when the parking spot request data is received from the vehicle 100, the control unit 20 acquires a combination of the vehicle type and the driving skill level associated with the identification code indicated by the parking spot request data. Then, the control unit 20 sets, as the target parking frame, the parking frame T having the higher passing frequency indicated by the passing frequency information 30a1 corresponding to the combination of the vehicle type and the driving skill level associated with the identification code indicated by the parking spot request data. To do. As described above, the target parking spot can be set based on the passing frequency suitable for the vehicle type of the vehicle and the driving skill of the driver.

  Furthermore, the passing frequency of the present invention may be acquired for each weather during parking. Therefore, in the recording medium 30 of the target parking spot setting system 10, the passing frequency information 30a1 may be recorded for each weather. When receiving the probe data from the vehicle 100, the control unit 20 acquires the weather of the parking lot P at the parking time based on the weather information received from the weather server 200. And the control part 20 updates the passage frequency which the passage frequency information 30a1 corresponding to the weather of the parking lot P in a parking time shows. When receiving the parking spot request data from the vehicle 100, the control unit 20 acquires the weather at the scheduled arrival time at the destination G indicated by the parking spot request data based on the weather information received from the weather server 200. Then, the control unit 20 sets the parking frame T having the higher passing frequency indicated by the passing frequency information 30a1 corresponding to the weather at the scheduled arrival time at the destination G as the target parking frame. As described above, the target parking spot can be set based on the passing frequency suitable for the weather at the time of parking.

  Here, when the weather of the destination G is the second weather which is worse than the first weather, the control unit 20 selects the parking spot which has been selected by giving priority to the low passing frequency over the first weather. You may set as a target parking spot. Specifically, when the weather at the destination G is rain or snow as the second weather, the control unit 20 sets the target parking frame by the method of the first embodiment. On the other hand, when the weather of the destination G is clear or cloudy as the first weather, the control unit 20 may set the target parking frame based on an evaluation factor other than the passing frequency. For example, when the weather at the destination G is clear or cloudy, the control unit 20 sets the parking frame T with the short walking distance to the destination G or the parking frame T as the target parking frame. May be.

  Here, it can be estimated that the number of users who want to park in the convenient parking frame T increases as the weather worsens. That is, it can be estimated that the popularity tendency of the parking frame T appears more prominently as the weather is worse, and more users want to park in the parking frame T having a higher popularity. Therefore, when the weather of the destination G is bad, the parking frame T having a low passing frequency and high popularity is used as the target parking frame, so that the parking frame T that the user thinks to park when the weather is bad is recommended or Can be subject to parking.

  In the present invention, the target parking spot may not be a parking spot recommended to the user, but may be a parking spot that is the end point of the planned movement route of the vehicle 100. The planned movement route may be a route that is subject to route guidance in the vehicle 100 or may be a route that is subject to automatic driving. When the target parking point is set as the end point of the planned movement route of the vehicle 100, the control unit 20 sets the parking frame T having the lowest passing frequency as the target parking frame by the function of the target parking point setting module 21b. That's fine.

  In the said embodiment, although the target parking spot was set per parking frame, the control part 20 may set a target parking spot per parking lot, and for every parking area comprised with a several parking frame. It may be set. For example, the control unit 20 does not park in the parking lot P guided as an empty parking lot P around the destination G, but parks in another parking lot P and visits the destination G when parking. The added value may be added to the passing frequency of the parking lot P that has not been used. And when setting a target parking lot from the parking lots P around the destination G, the control unit 20 may set a parking lot P having a lower passing frequency as a target parking lot. Whether there is an empty vehicle in the parking lot P may not be acquired based on the probe data, and may be acquired based on, for example, full / empty vehicle information provided by the administrator of the parking lot.

  Furthermore, the control unit 20 sets the parking frame rows H1 to H6 having a small total value for the parking frame rows H1 to H6 shown in FIG. 2 by summing the passing frequencies of the parking frames T belonging to the parking frame rows H1 to H6. You may preferentially set it as a target parking frame row. Moreover, in the structure which sets an object parking frame based on the passing frequency for every parking frame T like 1st Embodiment, the parking frame T which compares a passing frequency is not restricted to the parking frame T in a single parking lot. . That is, the control unit 20 may select the parking frame T set as the target parking frame by comparing the passing frequency of the parking frame T across a plurality of parking lots.

  In the present invention, the target parking spot setting system only needs to be an apparatus that sets at least the target parking spot, and may be an apparatus different from the in-vehicle apparatus that performs driving support related to the target parking spot. That is, the target parking spot setting system may be an apparatus that provides information indicating the target parking spot to the driving support apparatus related to the target parking spot. Of course, the target parking spot setting system may be a part of an in-vehicle device or a vehicle that provides driving support for the target parking spot. The recommended parking spot is a parking spot recommended for the user. The parking spot to be parked is a parking spot where the vehicle parks. Further, a route to a parking spot to be parked may be guided, or automatic driving for parking at a parking spot to be parked may be performed.

  The passing frequency may be an index indicating the frequency that the vehicle passes through even though the parking spot is an empty vehicle, and may be the number of times the vehicle passes through the parking spot, or the probability that the vehicle passes through the parking spot. There may be. Passing through means passing through a parking spot without parking although it recognizes that it is an empty car. For example, it may be determined that the vehicle has passed through the parking spot when the vehicle has passed through an area where the empty vehicle condition at the parking spot can be visually recognized. Furthermore, the pass may be that the vehicle has passed the parking spot even though there is an intention to park, and it may be determined that the user has passed the parking at another parking spot after passing the parking spot.

  The target parking spot setting unit may set the second parking spot whose passing frequency is lower than that of the first parking spot as a target parking spot in preference to the first parking spot. You may preferentially set it as a target parking spot. The number of parking spots set as the target parking spot is not limited to one and may be plural. In this case, it is only necessary for the plurality of parking spots set as the target parking spots to have a lower passing frequency than the parking spots not set as the target parking spots.

  Here, the parking spot may be a parking frame. Thereby, the parking frame which a user wants to park can be set as an object parking spot. A parking frame is an area in a parking lot that is partitioned for one vehicle to park. However, the parking spot is not limited to the parking frame, and may be a parking lot or a group constituted by a plurality of parking frames. Specifically, the parking spot may be a row of parking frames or a parking area formed in the parking lot.

  The passing frequency acquisition unit may acquire the passing frequency based on an empty vehicle condition of the parking frame detected in the vehicle. In this configuration, since the empty vehicle condition is detected by the vehicle that has actually passed through the parking frame, it is possible to accurately acquire the passing frequency for each parking frame. For example, the passing frequency may be acquired based on an image recognition process of an image captured from a vehicle, or the passing frequency may be acquired based on a detection result of a parked vehicle by a radar. On the other hand, when the parking spot is not a parking frame but a parking lot, the passing frequency of the parking lot may be acquired based on the full / empty vehicle information of the parking lot and the movement information of the vehicle.

  Further, the passing frequency may be a frequency of passing through a parking spot even though the vehicle before parking is an empty vehicle. That is, by not counting the frequency with which a user's vehicle that has already been parked and has no intention of parking passes, a highly reliable passing frequency can be obtained.

  Here, when the weather at the destination is the second weather which is worse than the first weather, the parking spot selected with priority on the low passing frequency over the first weather is set as the target parking spot. May be. It can be estimated that the worse the weather, the greater the number of users who want to park at a convenient parking spot. That is, it can be estimated that the popularity tendency of the parking spot appears more prominently as the weather is worse, and more users want to park in the parking lot with higher popularity. Therefore, if the weather at the destination is bad, the parking spot that is low in passing frequency and high in popularity is used as the target parking spot. It can be.

  Here, the passing frequency may be acquired for each vehicle type, for each driving skill of the driver of the vehicle, or for each weather at the time of parking. Thereby, the target parking spot can be set based on the vehicle type of the vehicle, the driving skill of the driver, and the passing frequency suitable for the weather at the time of parking.

  Furthermore, the method of preferentially recommending or parking a parking spot with a low passing frequency as in the present invention can also be applied as a program or method. In addition, the system, program, and method as described above may be realized as a single device, or may be realized using components shared with each part of the vehicle, and include various aspects. It is a waste. For example, it is possible to provide a navigation system, a navigation system, a method, and a program that include the above devices. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also established as a recording medium for a program for controlling the apparatus. Of course, the software recording medium may be a magnetic recording medium, a semiconductor memory, or any recording medium that will be developed in the future.
