  The present invention relates to a parking position guide device for guiding a parking position to a user of a vehicle via a vehicle and a communication line.

2. Description of the Related Art Conventionally, an invention related to a navigation device that displays a parking lot based on a user's wishes such as parking lot opening hours, vehicle type regulation conditions, and charges is known (see, for example, Patent Document 1). In this invention, the destination or the nearby parking lot input by the user is searched from the data related to the parking lot, and the parking lot that is open at a predetermined date and time from the search results, the vehicle width of the user's vehicle, the vehicle height It is possible to display a parking lot according to the user's request by displaying a parking lot that matches the conditions of the vehicle type or acquiring congestion information and vacant information of the parking lot.
JP 2001-349740 A

  However, although the above-mentioned prior art can select a parking lot according to the user's wish before arriving at the parking lot, when the user arrives at the parking lot and tries to park, Then, there is not always a desirable parking position for the user.

  That is, when it demonstrates with reference to FIG. 10 showing an example of the parking state of a parking lot, even if a user wants to park as close to the destination as possible, and wants to park in as wide a parking position as possible (parking position 11), There was a case where it was guided to another vacant parking position. Furthermore, since a parked vehicle or the like that is already parked is parked out of the parking position, there is no space for parking at the size of the user's vehicle, or because the user's driving skill is immature, the user is parked. May be a difficult space (parking positions 2 and 18).

  The reason for the inconvenience for the user in the parking lot is that the information on whether or not each parking position in the parking lot is vacant provides uniform information for all users. Met.

  Then, an object of this invention is to provide the parking position guidance apparatus and vehicle-mounted parking position guidance apparatus which can guide a parking position effectively.

In order to solve the above-described problem, according to one aspect of the present invention, in a parking position guidance apparatus that guides a parking position to a user of a vehicle via a communication line, preference information acquisition means for acquiring user preference information regarding the parking position. And, based on the preference information acquired by the preference information acquisition means, a parking position determination means for determining a parking position according to a user's preference from among parking positions that can be parked in a parking lot, and the parking position determination means Parking position transmission means for transmitting the parking position determined by the user to the user , wherein the preference information acquisition means predicts the user's preference based on the user's past parking position and the parking situation in the parking lot at that time. Then , a parking position guide device is provided, wherein the preference information is generated . In addition, the parking position determined by the parking position determination means does not necessarily need to be singular.

  Thereby, by predicting the user's preference from the user's past parking position and the parking situation in the parking lot at that time, the parking position is guided without setting or inputting the conditions regarding parking each time the user parks. be able to.

  In this aspect, the parking position determination means may execute the parking position determination based on parking space information regarding a parking space at each parking position in a parking lot.

  Thereby, the parking position which a user desires can be determined from the parking position with the parking space which can park the own vehicle in a parking lot.

Moreover, in order to solve the said subject, according to 1 aspect of this invention, in the parking position guidance apparatus which guides a parking position to the user of a vehicle via a communication line, the preference information which acquires the user's preference information regarding a parking position Based on the preference information acquired by the acquisition means, the preference information acquisition means, a parking position determination means for determining a parking position according to a user's preference from among parking positions that can be parked in a parking lot, and the parking position Parking position transmission means for transmitting the parking position determined by the determination means to the user, the parking position determination means determines the parking position based on the parking space information regarding the parking space of each parking position in the parking lot. A parking position guide device is provided in which the parking space information is corrected based on a parking state of a parked vehicle in the vicinity of the parking space.

  As a result, even if the parking space information of a certain parking position is “empty”, depending on the parking state of a parked vehicle parked in the vicinity of the parking space, the parking position is narrow for the user. The parking space information may be corrected based on the parking state of the parked vehicle in the vicinity of the parking space, and the desired parking position may be determined except for the parking position where the user cannot park. it can.

  In this aspect, the parking state of the nearby parked vehicle is determined based on the vehicle position information of the parked vehicle sent from the parked vehicle.

  As a result, by obtaining vehicle position information of parked vehicles parked in the vicinity of the parking space, it is possible to predict where the parked vehicles in the vicinity of the parking space are parked, and to obtain the actual parking space according to the positional relationship Therefore, it is possible to guide the parking position with higher accuracy.

  In this aspect, the parking state of the nearby parked vehicle is determined based on distance information between the parked vehicle and another parked vehicle sent from the parked vehicle.

  Thereby, since an actual parking space can be calculated | required from the distance between the parking vehicle of the parking space vicinity, and another parking vehicle, a more highly accurate parking position can be guided.

In this aspect, the preference information may include information based on the user's personal information.
Thus, for example, if the personal information of the user is “wheelchair user” as the personal information of the user, it is considered that there is a preference that the user wants to park at a parking position for a disabled person or a parking position wider than usual. You can guide the parking position in consideration of the preference that you want to park at a parking position where the walking distance to the destination is short if it is personal information of "elderly" it can.
In this aspect, the parking position determination means may execute the parking position determination based on a weather condition around the parking lot.
Thus, for example, when it rains, the parking position is determined according to changes in the environment such as the weather by considering the need to park in a covered parking lot or underground parking lot so that it does not get wet in the rain be able to.
In this aspect, the parking position determination means may execute the parking position determination based on driving ability information related to a user's driving skill .

  Thereby, since the parking position according to a user's driving skill is determined, the parking position where it is easy to park can be guided with respect to the user who is not good at parking.

  In this aspect, in the parking position guidance device that guides the parking position to the user in an interactive manner, the parking position determination means, when the parking position determined by the user by the parking position determination means is denied, again another parking position A parking position guidance device is provided.

  Thereby, since the determined parking position may be unsatisfactory for the user, in that case, the user can select a parking position as close as possible to his / her needs by determining the parking position again.

  In this aspect, the parking position determination means determines a parking position transmitted by the parking position transmission means in an order according to the preference information from among a plurality of parking positions that can be parked in the parking lot. Good.

  Thereby, a parking position can be specified early by determining a parking position in order from a thing close | similar to a user preference.

  In this aspect, the parking position determination means may estimate the parking position in the parking lot at an estimated arrival time when the user's vehicle arrives at the parking lot, and determine the parking position.

  Thereby, based on the estimated arrival time when the user's vehicle arrives at the parking lot, for example, a parking position that can be parked in the parking lot at that time can be reserved, and the parking position can be reserved for other vehicles. Since it can cope beforehand so that it may not park, when a user arrives at a parking lot, a parking position according to a user's taste can be secured.

  Further, in another aspect, the vehicle-mounted parking position guide device connected to the parking position guide device through a communication line, the notification means for notifying the user of the parking position transmitted by the parking position transmission means. An in-vehicle parking position guide device is provided.

  Thereby, the user moves the vehicle to the parking position according to the user's own preference by receiving the parking position guided from the parking position guiding device via the communication line and notifying the user of the parking position. be able to.

  In this aspect, the on-vehicle parking position guidance device connected to the parking position guidance device via a communication line, the vehicle position detection means for detecting the vehicle position of the host vehicle, and the vehicle position detected by the vehicle position detection means A vehicle-mounted parking position guide device is provided, comprising: a transmission unit that transmits the vehicle position information to the parking position guide device as the vehicle position information.

  Thereby, a some vehicle transmits the vehicle position of the own vehicle to a parking position guidance apparatus, and the parking position guidance apparatus can estimate the position state of the several vehicle in a parking lot. Therefore, if the vehicle position of the parked vehicle in the vicinity of the parking space is transmitted, the actual parking space can be obtained from the positional relationship of the vehicle position, so the parking position guide device guides the parking position with higher accuracy. can do.

  In this aspect, the on-vehicle parking position guidance apparatus connected to the parking position guidance apparatus via a communication line, the distance detection means for detecting the distance between the own vehicle and another vehicle, and detected by the distance detection means Transmitting means for transmitting a distance to the parking position guide device as the distance information is provided.

  Thus, the actual parking space can be obtained by measuring the distance between the parked vehicle in the vicinity of the parking space and the other parked vehicle and transmitting the distance information to the parking position guiding device. The guidance device can guide the parking position with higher accuracy.

  According to the present invention, it is possible to effectively guide the parking position according to the personal preference.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram of the entire system showing an embodiment of the present invention. The parking position guidance device 100, a plurality of vehicles 200, and a vehicle 300 (hereinafter referred to as a guided vehicle 300) to be parking-guided from now on are configured. The parking position guide device 100 transmits and receives information between each of the plurality of vehicles 200 and the guided vehicle 300 using a communication function (for example, a mobile phone, a wireless LAN, or a DSRC (Dedicated Short-range Communication)). The parking position guidance apparatus 100 does not necessarily need to be singular, and a plurality of parking position guidance apparatuses 100 may be installed for each certain range. For example, a plurality of parking lots installed in a certain area may be managed or installed in each parking lot.

  The plurality of vehicles 200 and guided vehicle 300 are equipped with on-vehicle parking position guidance devices (204, 304). The on-vehicle parking position guidance devices (204, 304) include own vehicle information acquisition processing means (203, 303), notification means (202, 302), and communication means (201, 301).

  FIG. 9 is a diagram showing an example of the own vehicle information acquisition processing means (203, 303). The own vehicle information acquisition processing means (203, 303) indicates destination information 305 indicating the position of the destination that the user intends to go from now on, vehicle position information indicating the position of the own vehicle, and the size of the own vehicle. Vehicle information (206, 306) whose element is own vehicle size information, preference information 307 whose element is a preference when the user is parked, and driving ability information 308 related to the user's driving skill are acquired.

  The vehicle position information is measured by, for example, RTK-GPS (Real Time Kinematic Global Positioning System) capable of highly accurate position detection. RTK-GPS is a GPS surveying machine installed at the reference observation point (fixed point) and the observation point (moving point) as the reference point, and simultaneously receives signals from GPS satellites. This is a surveying method in which a position is determined by transferring to a moving point using a wireless device or the like and immediately performing a baseline analysis on the moving point side.

  In order to further improve the accuracy of the vehicle position information, distance information from a camera or radar that measures lane detection and distance between vehicles, vehicle speed information from a vehicle speed sensor, or the like may be used in combination.

  The own vehicle size information is a value such as a total length, a total width, a total height, and the like that represents an outer dimension of the vehicle. Any value can be used as long as it can be determined whether or not the vehicle can be parked in the parking space.

  The preference information 307 indicates the tendency of the user to park (for example, park as close as possible to the destination, park in a large parking space even if away from the destination, parking fees are high on rainy days And the like, and parking tendency information having a factor such as parking in an underground parking lot or a covered parking lot, and personal information having user-specific information such as that the user is a wheelchair user.

  Here, examples of means for determining environmental information (weather condition such as rain) include a sunshine sensor, a temperature sensor, and a rain sensor, which are mounted on a vehicle. Means for judging the weather condition are not necessarily required, and it can be substituted by defining that the weather is judged to be rain when the wiper is operated for a certain period of time.

  The driving ability information 308 is a driving ability that becomes an element for determining a parking position to be guided by the user's driving skill (for example, parking is possible even in a narrow parking space, there are many turnovers when parking, there is a slow start, the brake timing is This is information indicating a slow position, a traveling position and speed for a lane during normal traveling, a narrow inter-vehicle distance, and the like. Not only the driving ability when parking, but also the driving ability when traveling normally may be included as information.

  As a method of acquiring the preference information 307, the driving ability information 308, etc., the user's past parking position and the parking situation and running state in the parking lot at that time are uploaded to the parking position guide device 100 to predict the user's preference. Then, preference information and driving ability information may be generated, and a user's past parking position, running state, and the like are stored and stored in a drive information storage unit (for example, a drive recorder such as an HDD) mounted on the vehicle. The vehicle information may be learned in the vehicle based on the past information, and the vehicle information acquisition processing means (203, 303) may acquire the generation result. According to the uploading method described above, it is not necessary to provide a memory for storing such information on the vehicle side, or the use area of the memory can be reduced. To further list other acquisition methods, preference information and driving ability information are set as predetermined items (for example, parking as close to the destination as possible, parking in a narrow parking space, etc.) It is good also as a structure which a user selects those determined items and the own vehicle information acquisition process means (203, 303) acquires the selection items.

  Returning to FIG. 1, the notifying means (202, 302) notifies the user of the parking position guided from the parking position guiding apparatus 100. For example, a car navigation system is used to visually display a map or guidance information in a parking lot on a display or to provide voice guidance. Moreover, it has the function to judge the reply result which inquired the user about whether or not this parking position is acceptable for the notified parking position.

  The communication means (201, 301) obtains the destination information 305 obtained by the own vehicle information acquisition processing means (203, 303) indicating the position of the destination that the user intends to go from now on, and the existence position of the own vehicle. Vehicle information (206, 306) whose elements are vehicle position information to be shown and own vehicle size information indicating the size of the own vehicle, preference information 307 whose elements are preferences when the user is parked, and user driving skills Driving capability information 308 related to the parking position guidance device 100 and a function of receiving data from the parking position guidance device 100.

  FIG. 2 shows destination information 305 that is acquired by the own vehicle information acquisition processing means (203, 303) and that indicates the position of the destination that the user intends to go from now on, vehicle position information that indicates the position of the own vehicle, and Vehicle information (206, 306) whose element is own vehicle size information indicating the size of the own vehicle, preference information 307 whose element is a preference when the user is parked, and driving ability information 308 of the individual user An example of the data at the time of transmitting to the parking position guidance apparatus 100 is shown. The data 400 includes a header 410, destination information 420, vehicle information 430, preference information 440, and driving capability information 450. When the information acquired by the own vehicle information acquisition processing unit 303 of the guided vehicle 300 is transmitted, the destination information 305, the vehicle information 306, the preference information 307, and the driving ability information 308 are entered in each area.

  In the header 410, a data type 411 that represents the structure and contents of the data 400, a destination address 412 that represents the destination of the data 400, and a source address 413 that represents the transmission source of the data 400 are described. The receiver side processes the data after the header.

  For example, if the data type 411 includes “user information transmission”, it is defined as transmission of the data 400 having the structure shown in FIG.

  Here, it is possible to send only necessary information by changing the description of the data type 411. FIG. 8 is an example of data for transmitting vehicle position information 431 and destination information 420. For example, if there is a description “parking position guidance request” in the data type 411, it is defined as transmission of data 401 having the structure shown in FIG.

  Further, the destination address 412 contains the IP address of the parking position guide device 100, and the source address 413 contains the IP address of the vehicle that transmitted the data 400. Here, as a technique for assigning an IP address, for example, there is IPv6 (Internet Protocol Version 6), and a different IP address can be assigned so that each vehicle can be identified.

  The destination information 420 indicates the position of the destination that the user intends to go from now on.

  The vehicle information 430 includes vehicle position information 431 and own vehicle size information 432 at the time of data transmission.

  The preference information 440 includes parking tendency information 442 and personal information 443 at the time of data transmission. For example, “park as close as possible to the destination” is input to the parking tendency information 442, and “wheelchair user”, “right-hand drive vehicle”, and “left-hand drive vehicle” are input to the personal information 443.

  The driving capability information 450 indicates driving capability information at the time of data transmission. For example, “Parking is possible even in a narrow parking space” is input.

  FIG. 3 shows an example of data when the vehicle-mounted parking position guide devices (204, 304) receive the parking instruction position information 520 guided from the parking position guide device 100. The data 500 includes a header 510 and parking instruction position information 520.

  In the header 510, a data type 511 that represents the structure and contents of the data 500, a destination address 512 that represents the destination of the data 500, and a source address 513 that represents the transmission source of the data 500 are described. Perform data processing. Here, if the data type 511 includes, for example, “parking instruction position information transmission”, it may be defined that the data 500 having the structure shown in FIG. 3 is transmitted. The destination address 512 contains the IP address of the guided vehicle 300, and the source address 513 contains the IP address of the parking position guide device 100.

  The parking instruction position information 520 indicates a parking position where the guided vehicle 300 that has received the data 500 and is guided by the parking position guide device 100 can be parked.

  Next, the configuration of the parking position guide device 100 will be described in detail with reference to FIG. 1 and FIGS. The parking position guidance device 100 includes a communication unit 101, a parking lot information database (a storage device such as a hard disk that can be read and written by a computer, hereinafter abbreviated as DB) 103, a driving ability information DB 104, a personal preference information DB 105, The information acquisition means 106, the parking position determination means 107, and the parking position transmission means 102 are comprised. Here, the parking lot information DB 103, the driving ability information DB 104, and the personal preference information DB 105 are not necessarily provided in the same parking position guide device 100, but are separated by transmitting and receiving information by information transmission means such as communication. You may prepare. Further, although the DB is configured separately for convenience of explanation, it may be realized on the same database.

  The communication unit 101 is a communication interface with the guided vehicle 300 and the plurality of vehicles 200, and information is transmitted / received via the communication unit 101.

  As shown in FIG. 4, the parking lot information DB 103 has a parking lot file 660 for each parking lot, and the parking space information 600 of each parking position in the parking lot with high accuracy is stored for each parking lot file 660. .

  The parking lot file 660 stores parking lot position data 610 and parking lot exit position data 620 representing the parking lot existence position, which is data specific to the parking lot, and parking space information 600 of each parking position in the parking lot. The

  The parking space information 600 of each parking position in the parking lot includes, for example, parking position data 630 representing each parking position provided in the parking lot, and parking position space data 640 representing the size of each parking position (for example, a plane In other words, the full width and total length of the allowable parking limit of the vehicle, and in three dimensions, the full width, full length, and total height of the allowable parking limit of the vehicle, and a parking position that indicates whether there is a vehicle in each parking position. It consists of data 650. The parking space information 600 for each parking position in the parking lot is preferably obtained in real time from a parking lot provider or the like.

  Here, the parking position in which the parking position vacancy data 650 is “empty” is not necessarily a space where parking is possible in an actual parking lot depending on how the vehicle is parked. That is, when a parked vehicle or the like that is already parked protrudes from the parking space, the space that can be parked is small and parking is difficult. Therefore, in an actual parking lot, there is not necessarily a desirable parking space, and parking guidance may not function sufficiently. Therefore, the vehicle position information 431 and the own vehicle size information 432 of the plurality of vehicles 200 in the vicinity of the parking space of the parking position data 630 in which the parking position vacancy data 650 is “empty” are read, and the distance between the plurality of vehicles 200 is determined. The parking position space data 640 is corrected from the measured distance information.

  As a result, the parking position space data 640 of the parking position data 630 in which the parking position vacancy data 650 is “empty” can be corrected. Therefore, it is accurately determined whether the guided vehicle 300 is a parking space. Thus, the parking guidance accuracy can be increased.

  For example, when the parking space for one vehicle is vacant, if the distance between two vehicles already parked on both sides of the parking space is measured, the actual width of the parking space can be obtained. it can. Therefore, even if there is parking position data 630 in which the parking position vacancy data 650 is “empty”, the space for parking for the guided vehicle 300 by correcting the parking position space data 640 by the measurement method. If it is narrow and it is determined that parking is impossible, it can be excluded from the parking position candidates. Examples of the method for measuring the distance between the plurality of vehicles 200 include an RTK-GPS surveying method and a method of measuring the lateral distance of the vehicle using a distance measuring sensor provided in the vehicle left-right method.

  The driving capability information DB 104 is provided for storing a determination element for guiding a parking position where parking is easy for a user who is not good at driving, and is attached to the vehicle as in the data structure shown in FIG. The driving capability data 700 including the user-specific user ID 710 and the driving capability information 450 corresponding one-to-one with the IP address is stored.

  As shown in the data structure shown in FIG. 6, the personal preference information DB 105 includes personal preference data including a user ID 710 unique to a user corresponding to an IP address assigned to a vehicle, vehicle information 430, and preference information 440. 800 is saved.

  The information acquisition unit 106 acquires the data 400 and the data 401 transmitted from the in-vehicle parking position guide device (204, 304) via the communication unit 101, and the vehicle information 430 and the preference information 440 are stored in the personal preference information DB 105. The driving ability information 450 has a function of saving or updating in the driving ability information DB 104. Further, it has a function of transferring the IP address of the guided vehicle 300 at the source address 413 to the parking position determining means 107.

  Based on the vehicle position information 431 in the vehicle information 430 stored in the personal preference information DB 105 and the destination information 420, the parking position determination means 107 has an appropriate standard (for example, the positional relationship with the guided vehicle 300). A parking lot file 660 that satisfies a range of 1 km or the like is extracted from the parking information DB 103. In addition, the correction data of the parking space is obtained by measuring the distance between the plurality of parked vehicles 200 based on the vehicle position information 431 and the own vehicle size information 432 of the plurality of vehicles 200 stored in the personal preference information DB 105. The parking position space data 640 is updated to the parking space correction data. Further, based on the preference information 440 in the personal preference data 800 stored in the personal preference information DB 105 and the driving capability information 450 in the driving capability data 700 stored in the driving capability information DB 104, the extracted parking lot is used. A parking instruction that indicates that the guided vehicle 300 can be physically parked from the candidates of the parking space information 600 for each parking position in the parking lot of the file 660 and that indicates the parking position that meets the user's preference and driving skill. The position information 520 is determined.

  The parking position transmission means 102 has a function of attaching the parking instruction position information 520 determined by the parking position determination means 107 to the header 510 and transmitting the data 500 to the guided vehicle 300 via the communication means 101. Have.

  Next, an example of the operation in the embodiment of the present invention will be described with reference to FIG. FIG. 7 is a flow of operation processing of the embodiment.

  When a user boarding the guided vehicle 300 requests parking guidance, the vehicle information acquisition processing unit 303 of the on-vehicle parking position guide device 304 displays destination information indicating the position of the destination that the user intends to go from now on. 305, vehicle information 306 including vehicle position information indicating the presence position of the vehicle and vehicle size information indicating the size of the vehicle, and preference information 307 including a user's personal parking preference as elements. The driving ability information 308 related to the user's driving skill is acquired (S100).

  The communication unit 301 attaches each information acquired in S100 to the header 410 and transmits the data 400 to the parking position guide device 100 (S101).

  However, the vehicle size information 432, the preference information 440, and the driving ability information 450 have already been transmitted to the parking position guidance device 100, and are already stored in the driving ability information DB 104 and the personal preference information DB 105. If there is no change in the content, the vehicle position information 431 and the destination information 420 may be transmitted as in the parking position data 401. This means that it is not necessary to set the conditions regarding the parking which a user desires every time it parks.

  On the other hand, in the parking position guidance apparatus 100, the information acquisition means 106 acquires the data 400 or 401 transmitted from the vehicle-mounted parking position guidance apparatus 304 via the communication means 101 (S102).

  In S103, the information acquisition unit 106 stores or updates the vehicle information 430 and the preference information 440 in the personal preference information DB 105 and the driving capability information 450 in the driving capability information DB 104 for the acquired data 400 or 401, and the source address 413. The IP address of the guided vehicle 300 is transferred to the parking position determination means 107. By this transfer, the parking position determination unit 107 can uniquely identify the guided vehicle 300.

  In S104, the parking position determination unit 107 determines whether the positional relationship with the guided vehicle 300 is appropriate based on the vehicle position information 431 in the vehicle information 430 stored in the personal preference information DB 105 and the destination information 420. A parking lot file 660 that satisfies (for example, within 1 km) is extracted from the parking information DB 103.

  In S105, the correction data of the parking space is obtained by measuring the distance between the plurality of parked vehicles 200 based on the vehicle position information 431 and the own vehicle size information 432 of the plurality of vehicles 200 stored in the personal preference information DB 105. The parking position space data 640 is updated to the parking space correction data.

  The correction of the parking position space data 640 in S105 will be described in more detail with reference to FIG. FIG. 11 is a detailed processing flow of S105.

  In S200, when the parking position guidance apparatus 100 requests vehicle position information for a plurality of parked vehicles 200 adjacent to the parking position data 630 (parking position 18 in FIG. 10), a plurality of adjacent parking position data 630 are used. The own vehicle information acquisition processing unit 203 of the on-vehicle parking position guide device 204 of the parked vehicle 200 acquires the vehicle position information 431 and the own vehicle size information 432.

  In S210, the vehicle position information 431 and the own vehicle size information 432 acquired in S200 are read to the parking position determination means 107 of the parking position guide device 100, the distance between the plurality of parked vehicles 200 is measured, and the parking space is calculated from the measured distance. Find the correction data.

  In S230, the parking position space data 640 of the corresponding parking position data 630 (parking position 18) is updated to the calculated parking space correction data.

  Here, in the description of the detailed flow of S105 described above, the vehicle position information 431 of the plurality of parked vehicles 200 adjacent to the parking position data 630 is read and the parking space correction data is obtained from the positional relationship. The distance information is read by measuring the distance to other parked vehicles using a distance measuring sensor such as a camera or radar mounted on the parked vehicle. It may be configured as desired.

  Returning to FIG. 7, in S106, based on the preference information 440 in the personal preference data 800 stored in the personal preference information DB 105 and the driving capability information 450 in the driving capability data 700 stored in the driving capability information DB 104, The guided vehicle 300 can be physically parked from the candidates for the parking space information 600 at each parking position in the parking lot of the extracted parking lot file 660, and the user's preference and driving skill are met. Parking instruction position information 520 is determined.

  Here, the information already stored in the personal preference information DB 105 and the driving ability information DB 104 can be used as the judgment information, but is predicted from the saved preference information 440 and the driving ability information 450 as new judgment information. You can also. For example, based on the user's past parking position and the parking situation in the parking lot at that time (parking space information of each parking position, etc.), it is known how the user has parked in the parking situation in the past, Determination information can be generated by newly predicting user preference information 440 and driving ability information 450.

  Eventually, if a plurality of parking space candidates that match the user's preference and driving skill remain, ranking is performed according to a predetermined standard (for example, the order from the shortest distance from the vehicle position information 431, the parking space is wide) Order, etc.), the optimal candidate may be determined as the parking instruction position information 520, or all the candidates may be determined as the parking instruction position information 520.

  In S107, the parking instruction position information 520 determined by the parking position determination means 107 is attached to the header 510, and the data 500 is transmitted to the guided vehicle 300 via the communication means 101.

  On the other hand, in the guided vehicle 300, when the communication unit 301 receives the data 500 (S108), the notification unit 302 notifies the user of the parking instruction position information 520 guided from the parking position guide device 100 (S109). .

  In S110, it is determined whether or not the notified parking instruction position information 520 is an answer to the user as to whether or not this parking instruction position is acceptable. The information guided by the parking position guidance device 100 is not necessarily suitable depending on the feeling of the occupant at that time and the surrounding situation, so the user's intention is confirmed in the final decision.

  In the case of a reply result in which the notified parking instruction position information 520 is rejected, if there are a plurality of parking instruction position information 520 determined by the parking position determination means 107, the notification means 302 displays information on the next rank. invite.

  At this time, it is good also as a structure which transmits sequentially the parking instruction | indication position information 520 of the next order | rank from the parking position guidance apparatus 100 according to a user's refusal reply. It is also preferable that the parking instruction position information 520 is transmitted at one time, the information is temporarily stored on the guided vehicle 300 side, and the notification means 302 notifies the next rank candidate in response to the user's rejection response. It is. In this case, the number of times of transmission / reception with the parking lot apparatus guide device 100 is reduced, so that the communication cost can be reduced and the traffic of the parking position guide apparatus 100 and communication radio waves can be reduced.

  Here, if the rejection answer is included in the elements of the preference information 440, the own vehicle information acquisition processing unit 303 acquires the rejection answer and transmits it to the parking position guide device 100. The parking position guidance apparatus 100 can guide parking instruction position information other than the rejected parking instruction position information by considering the rejection answer as a user's preference again.

  On the other hand, when it is an acceptance reply of the notified parking instruction position information 520, the user moves the vehicle to the notified parking instruction position, and the flow ends.

  Here, if the acceptance answer is included in the elements of the preference information 440, it is transmitted to the parking position guidance apparatus 100 as in the case of the rejection answer. The parking position guidance apparatus 100 can guide the parking instruction position information more optimal for the user by considering the acceptance answer as the user's preference again.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  The above embodiment has been described in detail mainly on guiding the parking position in the parking lot, but of course, the parking lot position data 610 in the parking lot file 660 stored in the parking information DB 103, for example, parking lot sales By adding the user's desired conditions such as time, vehicle type regulation condition parking fee, etc. to the preference information etc., it is also possible to guide an empty parking lot itself according to the user's wishes.

  As another application example, if the information “wheelchair user” is entered in the personal information 443 in the preference information 440 either spontaneously by an input means or automatically by an image sensor or the like, the own vehicle The information acquisition processing unit 303 acquires the information, and the parking position guide device 100 extracts the parking space information 600 of each parking position in the parking lot having a parking space for a disabled person or a large parking space from the parking information DB 103. In addition, it is possible to guide the optimal parking position for the wheelchair user. In addition, if the information of “right-hand drive vehicle” or “left-hand drive vehicle” is entered, it is possible to guide a parking position where there is a parking space where the driver can easily get on and off, a parking space where the driver can easily enter from the rear of the vehicle, and the like.

  As another application example, if the information “the future schedule” in the personal information 443 in the preference information 440 (for example, when to get on the train for what hour, where to start the meeting, etc.), the parking position guidance The apparatus 100 determines whether the parking instruction position and the purpose are based on a predetermined condition (for example, even if the distance between the current vehicle position and the parking instruction position is not the shortest) based on the destination information of the schedule and the vehicle position information. The parking space information 600 of each parking position in the parking lot is extracted from the parking information DB 103 when the walking distance to the ground is short (that is, the parking position where the vehicle arrives at the destination as soon as possible), and the user The optimal parking position can be guided.

  As another application example, the driving ability information 450 for a plurality of user IDs 710 in the driving ability data 700 stored in the driving ability information DB 104 is extracted, and the extracted driving ability information 450 between the plurality of users is compared. By doing this, it is possible to determine a driving skill difference between a plurality of users, and by using this difference, the processing in the parking position guide device 100 can be reduced. For example, a driving item indicating a beginner is determined in advance (for example, there is a start / steepness, there are many turnovers during parking, etc.), and a user with a large number of driving items indicating the beginner in the driving ability information 450 can park. If it is a parking position, a user having a small number of driving items may determine that parking is possible at the parking position without considering other preference information.

  As another application example, since not only the guided vehicle 300 but also the positions of a plurality of other vehicles 200 can be grasped, immediately after the other vehicle 200 is instructed to the guided vehicle 300 about the parking position, Even if the parking instruction position is interrupted, the parking position guide apparatus 100 can grasp the situation and instruct the guided vehicle 300 to specify another parking position.

  Moreover, in the parking lot at the estimated arrival time when the user of the guided vehicle 300 arrives at the parking lot, it is possible to reserve a parking position where there is a space where parking is possible. Also, assuming that the parking position is reserved, it is possible to instruct other vehicles not to park at the parking position, or to guide the new parking position by excluding the parking position. it can. As a result, when the user arrives at the parking lot, the parking position according to the user's preference can be secured.

  In the text, for convenience, an IP address assigned to a vehicle and a user ID unique to the user are in a one-to-one correspondence. However, a plurality of drivers may use one vehicle. In that case, it is preferable to manage the database by distinguishing a plurality of driver information in the IP address attached to the vehicle, and when a plurality of driver information is stored in advance in one IP address (corresponding to the vehicle). The vehicle information is the same by adding a step for confirming who is currently driving, but information on the driver currently driving may be applied to the driving ability and preference information.
