(Functional configuration of information guide device)
A functional configuration of the information guide apparatus 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram illustrating an example of a functional configuration of the information guide apparatus according to the embodiment. In FIG. 1, an information guidance device 100 is mounted on a moving body, and includes an acquisition unit 101, a setting unit 102, a determination unit 103, a guidance unit 104, and a destination setting unit 105. Yes.

  The acquisition unit 101 acquires information on a parking area in the parking lot. The parking lot is intended for any parking lot, and typically includes a large-scale flat parking lot and a three-dimensional parking lot. The parking area is an area obtained by partitioning a space where one vehicle is parked for each predetermined number. In the case of a multilevel parking lot, the number of parking floors may be a parking area, or may be the above partitioned area for each parking floor. This parking area is appropriately set for each parking lot according to the size of the parking lot. Parking area information includes information on the number of cars that can be parked for each parking area, information on the location of the parking area, information on whether the area is covered, and in the case of multilevel parking, underground, above ground, rooftop, etc. Information. In addition, the position information of the parking area may include information on a route in the parking lot, such as information on links and nodes, latitude / longitude information, and information on the number of parking floors in the multilevel parking lot.

  Predetermined conditions for preferential parking in the parking lot are set in the setting unit 102 in advance. Predetermined conditions include conditions desired by the user for parking, such as conditions for distances to connecting roads such as doorways to contact facilities such as stores, conditions for the degree of empty cars, conditions for whether or not the vehicle is covered, etc. It is. Further, the predetermined condition may be changed as appropriate by setting by a user's operation input.

  Based on the information on the parking area in the parking lot acquired by the acquisition unit 101 and the predetermined condition set in the setting unit 102, the determination unit 103 preferentially parks in the parking lot (predetermined parking area ( (Hereinafter referred to as “priority zone”). When the information on the parking area includes the information on the route in the priority area, the determination unit 103 may determine the route to the priority area based on the information on the route.

  The guide unit 104 performs guidance to the priority area determined by the determination unit 103. When the route to the priority area is determined by the determination unit 103, the guidance to the priority area may be guided to the priority area, or the route to the priority area is determined. If not, guidance may be provided to urge the priority area at the entrance / exit of the parking lot. The guidance by the guidance unit 104 may be voice guidance, guidance on a display screen, or both.

  Moreover, in this Embodiment, the acquisition part 101 may acquire the information of a parking area, and the positional information on the connecting path which contacts the feature of the vicinity of the said parking lot from the said parking lot. Specifically, the communication path is an entrance / exit of a feature or a connection path connecting to the entrance / exit. In this case, a distance-related condition is set in advance in the setting unit 102 as a predetermined condition. In addition, the determination unit 103 determines that the parking area closer to the connection path is based on the information on the parking area acquired by the acquisition unit 101, the position information of the connection path, and the conditions regarding the distance set in the setting unit 102. What is necessary is just to determine as a priority area with a high priority. In addition, the guidance unit 104 performs guidance to the priority area determined by the determination unit 103 in descending order of priority.

  This condition will be specifically described. The condition regarding the distance set in the setting unit 102 is a condition regarding the distance from the parking area to the communication path, which is set for each parking lot. It is a predetermined condition such as “the parking area with the shortest distance”. And the determination part 103 calculates the distance from each parking area to a connecting path based on the positional information on a parking area and the positional information on a connecting path. Then, based on a predetermined condition set in the setting unit 102, the smaller the calculated distance, that is, the shorter the distance from the parking area to the connecting road, the higher the priority parking area may be determined. .

  In such a configuration, the acquisition unit 101 may further acquire congestion information indicating whether or not parking is possible in the parking area. And in this case, the determination part 103 should just determine the parking area which can be parked as a priority area with a high priority in an order from the parking area near a connecting path based on the congestion information acquired by the acquisition part 101. FIG. The congestion information may be information indicating whether the vehicle is full or empty, or may be information indicating the degree of congestion. When the congestion information is information indicating whether the vehicle is full or empty, the area may be determined as a priority area when there is an empty car in the parking area. Further, when the congestion information is information indicating the degree of congestion, the priority may be lowered, for example, as the parking area is congested depending on the degree of congestion.

  Moreover, in this Embodiment, the acquisition part 101 may acquire the parking area | region information and the parking log | history in the parking area of the said parking lot based on the driving | running history of the other mobile body which shares driving | running | working data. In this case, the setting unit 102 is preset with a condition related to the number of times of parking history as a predetermined condition. In addition, the determination unit 103 is based on the information on the parking area acquired by the acquisition unit 101, the parking history of the parking area of another moving body, and the conditions regarding the number of parking histories set in the setting unit 102, A parking area with a higher number of parking histories may be determined as a priority area with higher priority. Moreover, the guide part 104 should just guide to the priority area determined by the determination part 103 in order with a high priority.

  In this configuration, a parking area with a long history of parking by another moving body is set as a priority area, and specifically, a parking area that is assumed to be highly convenient is set as a priority area. More specifically, this configuration is based on the premise that a system capable of sharing information on each moving body by connecting the moving bodies with each other via a network is used. Using this system, the acquisition unit 101 acquires parking histories of other moving objects. In addition, the condition related to the number of parking histories set in the setting unit 102 is a condition of the number of times other moving objects are parked, which is set for each parking lot. For example, “parking area with the highest number of parking” It is a predetermined condition. The determination unit 103 calculates the number of histories of other mobile objects parked for each parking area based on the parking area information and the parking histories of the other mobile objects. Then, based on a predetermined condition set in the setting unit 102, the determination unit 103 may determine a higher-priority parking area as the calculated number of times increases, that is, as the number of parking times increases.

  Moreover, in this Embodiment, the acquisition part 101 may acquire the information of a parking area and the unoccupied vehicle information which shows the unoccupied state for every parking area. In this case, the setting unit 102 is preset with a condition relating to an empty vehicle state as a predetermined condition. In addition, the determination unit 103 determines that the parking area with a vacancy is based on the information on the parking area acquired by the acquisition unit 101, the empty vehicle information for each parking area, and the conditions regarding the empty vehicle state set in the setting unit. What is necessary is just to determine as a priority area with a high priority. Moreover, the guide part 104 should just guide to the priority area determined by the determination part 103 in order with a high priority.

  This configuration guides a vacant parking area, for example, for a beginner or a user who desires a parking area that is not crowded. More specifically, the condition relating to the empty vehicle state set in the setting unit 102 is set for each parking lot. The empty vehicle rate in the parking area ((the number of empty vehicles in the parking area) / (allowable parking in the parking area). Number)), for example, a predetermined condition such as “a parking area with an empty vehicle ratio of 0% or more”. The determination unit 103 calculates an empty vehicle rate for each parking area based on the parking area information and the empty vehicle information. Then, the higher the calculated empty vehicle rate, that is, the parking lot that is not congested, is determined as a parking area with higher priority.

  In the above description, the priority area close to the connecting road, the priority area with many parking histories, and the vacant priority area are exemplified as an example. However, when deciding the priority, all of these can be added. It is. Specifically, it is a configuration in which a parking area having an empty vehicle ratio of a predetermined number or more, a lot of parking history, and close to a connecting road is determined as a priority area. More specifically, the predetermined condition set in the setting unit 102 is set such that the empty vehicle rate is not less than ○%, the parking history is not less than Δ times, and the distance to the connection path is not more than □ m. And you may make it determine as a priority area with high priority, so that all these conditions are matched or approximated. According to such a configuration, a parking area that is free to some extent and convenient can be set as a priority area.

  In the present embodiment, the destination setting unit 105 in which a destination is set is an arbitrary component. In this case, when the destination is set in the destination setting unit 105, the determination unit 103 may determine the priority area from the parking lots set in advance in association with the feature of the destination.

  In addition, when there are a plurality of facilities in the feature and there are a plurality of communication paths for contacting a parking lot set in advance in association with the feature, the destination setting unit 105 includes a plurality of facilities. When one of them is set, the acquisition unit 101 may acquire the facility location information and the location information of a plurality of communication paths. In this case, the determination unit 103 determines the connection path (hereinafter referred to as the shortest distance) to the facility from the plurality of connection paths based on the location information of the facilities acquired by the acquisition unit 101 and the position information of the connection paths. In this case, a parking area closer to the shortest connection path in the parking lot may be determined as a priority area having a higher priority.

  When this structure is demonstrated concretely, the feature in which several facilities exist is complex facilities, such as a department store and a shopping mall. The facility existing in the feature is a store or the like existing in the complex facility. The case where one of a plurality of facilities is set is a case where a certain store is set as a destination in such a complex facility. In this case, the acquisition unit 101 acquires store location information and entrance / exit location information as a connection path. The determination unit 103 selects an entrance with the shortest distance to the store, and determines a parking area closer to the entrance as a priority area with higher priority.

  In such a complex facility, when there are a plurality of parking lots, the acquisition unit 101 acquires the location information of the facilities, the location information of the plurality of parking lots, and the location information of the plurality of connection paths. That's fine. In this case, the determination unit 103 is based on the location information of the facility acquired by the acquisition unit 101, the location information of the plurality of parking lots, and the location information of the plurality of connection routes, from among the plurality of connection routes, Select the shortest connection. And the determination part 103 selects the parking lot close | similar to the shortest connection path out of several parking lots, and determines the parking area close | similar to the shortest connection path among the selected parking lots as a priority area with high priority. .

  This configuration assumes a case where a store is set as a destination in a complex facility having a plurality of parking lots. In this configuration, an entrance / exit closest to a store set as a destination and a parking lot close to the entrance / exit are selected, and a priority area of the selected parking lot is determined.

The priority area may be determined from the parking lots to be used. According to such a configuration, when a facility or the like is set as a destination, a parking lot associated with the destination can be searched as a destination, and a priority area of the parking lot can be determined.

  In addition, when there are multiple facilities in the feature and there are multiple communication paths that contact the parking lot set in advance in association with the feature, one of the multiple facilities is the destination. When it is set, based on the location information of the facility and the location information of the connecting route, the shortest connecting route is selected from a plurality of connecting routes. The priority area may be determined as a high priority area. According to such a configuration, even when there are a plurality of entrances and exits as communication paths, the user can park in a parking area close to the shortest connection path.

  In addition, when there are multiple parking lots, the shortest connecting route is selected from the plurality of connecting routes based on the facility location information, the multiple parking location information, and the multiple connecting location information. In addition to the selection, a parking lot that is closest to the shortest connection path is selected from a plurality of parking lots, and the parking area that is closest to the shortest connection path among the selected parking lots may be determined as a priority area with higher priority. .

(Example of priority area determination processing performed by the navigation device 300)
Next, an example of priority area determination processing performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of priority area determination processing performed by the navigation device 300 according to the present embodiment.

  In FIG. 6, the navigation apparatus 300 acquires parking lot information (step S601). And the acquired parking lot information is stored (step S602). Thereafter, the position information of the parking area for each parking lot is rearranged in order of priority (step S603). In determining the priority, for example, the priority is determined in the order from the closest to the connecting path based on a preset distance condition. Then, priority areas are determined in order of priority (step S604), and a series of processing ends.

(An example of processing to determine the priority area when the target facility is set)
Next, an example of processing for determining a priority area when a target facility is set will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of processing for determining a priority area when a destination facility is set.

  In FIG. 7, the navigation device 300 is in a standby state until the destination facility is set (step S701: No loop). When the destination facility is set (step S701: Yes), a parking lot is set in the destination facility. It is determined whether there is information (step S702). The fact that the destination facility has parking lot information means that there is a parking lot associated with the destination facility. If it is determined in step S702 that there is parking lot information (step S702: Yes), it is determined whether or not the parking lot is a parking lot having position information of the parking area (step S703).

  In step S703, when it is determined that the parking lot has the location information of the parking area (step S703: Yes), the priority area is determined (step S704). The priority area determination in step S704 is performed by the processing shown in the flowchart of FIG. Thereafter, based on the link number information and the like, the determined priority area is set as the destination point (step S705), and the series of processes is terminated.

  On the other hand, if it is determined in step S702 that there is no parking lot information (step S702: No), the destination facility is set as the destination point (step S706), and the series of processing ends. In step S703, when it is determined that the parking lot does not have the parking area position information (step S703: No), the parking lot is set as the destination point (step S707), and the series of processing ends.

(An example of processing to determine the priority area during route guidance)
Next, an example of processing for determining a priority area during route guidance will be described with reference to FIG. FIG. 8 is a flowchart illustrating an example of processing for determining a priority area during route guidance.

  In FIG. 8, it is assumed that the navigation apparatus 300 has a facility set as a destination and route guidance is being performed. And it is in a standby state until it becomes the timing which acquires parking lot information (step S801: No loop), and when it becomes the timing which acquires parking lot information (step S801: Yes), parking lot information is acquired (step S802). ). In addition, the timing which acquires parking lot information is arbitrary timings, such as the timing before the predetermined time or predetermined distance before arrival at a parking lot, the timing of the predetermined interval until it arrives at a parking lot, for example. Thereafter, it is determined whether or not the parking lot is a parking lot having the location information of the parking area (step S803).

  In step S803, when it is determined that the parking lot has the location information of the parking area (step S803: Yes), the priority area is determined (step S804). The priority area determination in step S804 is performed by the processing shown in the flowchart of FIG. Thereafter, based on the link number information and the like, the determined priority area is set as the destination point, and a re-search is performed (step S805). Then, it is determined whether or not the destination point has been reached (step S806). In step S806, when it is determined that the destination point has been reached (step S806: Yes), the series of processing ends.

  On the other hand, in step S803, when it is determined that the parking lot does not have the parking area position information (step S803: No), the process proceeds to step S806. If it is determined in step S806 that the destination has not been reached (step S806: No), the process proceeds to step S801.

  According to the process described above, the parking lot information is appropriately acquired until the vicinity of the target facility is reached. Therefore, the parking lot and the priority area as the destination can be changed as appropriate according to the traffic jam on the road and the full parking lot.

(An example of processing to determine the priority area when arriving at the destination facility)
Next, an example of processing for determining a priority area when arriving at a destination facility will be described with reference to FIG. FIG. 9 is a flowchart illustrating an example of processing for determining a priority area when arriving at a destination facility. Note that FIG. 9 also describes the guidance process (step S908) to the priority area when the position information does not include link number information.

  In FIG. 9, the navigation device 300 is in a standby state until it arrives at the destination facility (step S901: No loop), and when it arrives at the destination facility (step S901: Yes), it acquires parking lot information (step S902). . Thereafter, it is determined whether or not the parking lot is a parking lot having location information of the parking area (step S903).

  If it is determined in step S903 that the parking lot has position information of the parking area (step S903: Yes), the priority area is determined (step S904). The priority area determination in step S904 is performed by the process shown in the flowchart of FIG. Thereafter, it is determined whether there is link number information (step S905). If it is determined in step S905 that there is link number information (step S905: Yes), the priority area is set as the destination point and the search is performed again (step S906). And it guide | induces to the destination point (step S907), and complete | finishes a series of processes.

  On the other hand, in Step S903, when it is determined that the parking lot does not have the parking area position information (Step S903: No), the series of processes is terminated. If it is determined in step S905 that there is no link number information (step S905: No), the priority area is guided at the entrance of the parking lot (step S908), and the series of processing ends.

  As described above, the navigation device 300 according to the first embodiment determines the priority area to be preferentially parked in the parking lot, and provides guidance to the priority area. According to such a configuration, the parking position can be guided in the parking lot. Therefore, the user can park the moving body in a convenient parking area such as a parking area closest to the entrance / exit, for example, without making a determination by the user himself / herself.

  Even in a multi-level parking lot or a large parking lot that a user visits for the first time, the user can know where to park, so the user's anxiety can be resolved. Furthermore, even when the parking lot is familiar to the user, when the parking position desired by the user is full, other parking positions can be guided, so time for searching for the parking position is wasted. Can be prevented. As described above, according to this configuration, it is possible to smoothly reach a parking area that is convenient for the user, and it is possible not only to avoid useless driving but also to contribute to an improvement in fuel consumption. . Furthermore, environmental pollution can be reduced by reducing traffic congestion caused by searching for a parking area.

  The second embodiment of the present invention will be described below. Example 2 demonstrates the case where a complex facility has a plurality of parking lots and a plurality of communication paths that contact the parking lot. In the second embodiment, the description of the same configuration as that of the first embodiment is omitted as appropriate.

(An example of multiple parking lots and connecting roads in the complex)
An example of a plurality of parking lots and communication paths existing in a complex facility will be described with reference to FIG. FIG. 10 is an explanatory diagram illustrating an example of a plurality of parking lots and connection paths that exist in the complex facility according to the second embodiment.

  In FIG. 10, the complex facility 1000 includes a plurality of parking lots A to C. The complex 1000 has three stores a to c. The store a faces the parking lot A and has entrances 1001 to 1003 as communication paths. The store c is connected to an entrance / exit 1004 and connection paths 1011 and 1012 that contact the parking lots B and C.

(Example of parking area in parking lot A)
Next, an example of the parking area of the parking lot A will be described with reference to FIG. FIG. 11 is an explanatory diagram illustrating an example of a parking area of the parking lot A.

  In FIG. 11, the parking lot A has parking areas 1111 to 1116 obtained by dividing the parking space 1101 into predetermined numbers. In FIG. 11, reference numeral 1120 is the current position of the moving body, and reference numeral 1130 is a road facing the parking lot A. Assuming that the store a is set as the destination in the complex facility 1000 having such a parking lot A, the details will be described later using the flowchart shown in FIG. Among them, the parking areas 1111 to 1116 close to the entrance 1004 of the store a are determined as priority areas with high priority.

(Example of priority area determination process when multiple parking lots and communication paths exist)
Next, an example of priority area determination processing when a plurality of parking lots and communication paths exist will be described with reference to FIG. FIG. 12 is a flowchart illustrating an example of priority area determination processing when there are a plurality of parking lots and communication paths. In the flowchart shown in FIG. 12, a process will be described in which the store a in the complex facility 1000 is set as the destination and the priority area is determined in the middle of route guidance. In addition, each parking lot AC shall be a parking lot which has the positional information on a parking area, and about the judgment whether it is a parking lot which has the positional information on a parking area shown in step S803 of FIG. Omitted. In this flowchart, the priority area is determined in consideration of the congestion information of the parking area.

  In the flowchart of FIG. 12, the navigation device 300 is in a standby state until the destination is set (step S1201: No loop). When the destination is set (step S1201: Yes), the location information of the store a Is acquired (step S1202). And the positional information on parking lot AC linked | related with the complex 1000 is acquired (step S1203).

  Further, position information of a plurality of communication paths (entrances 1001 to 1004) for connecting the complex facility and the parking lots A to C is acquired (step S1204). Thereafter, based on the position information of the store and the position information of the plurality of connection paths, the shortest connection path (entrance / exit 1001) having the shortest distance to the store is selected from the plurality of connection paths (step S1205). . Based on the location information of the parking lots A to C and the location information of the shortest connection path, the parking lot A closest to the shortest connection path is selected from the parking lots A to C (step S1206).

  Thereafter, the congestion information of the parking areas 1111 to 1116 in the selected parking lot A is acquired (step S1207). And the parking area which can be parked in order from the parking area close to the shortest communication path (in the order of the parking areas 1111 to 1116) is determined as a priority area having a high priority (step S1208). Thereafter, the priority area is set as the destination point, and the search is performed again (step S1209).

  And until it arrives at the selected parking lot (step S1210: No), it transfers to step S1207, and when it arrives at the selected parking lot (step S1210: Yes), it guides to the destination point (step S1211). And until a vehicle parks (step S1212: No), it transfers to step S1211, and if a vehicle parks (step S1212: Yes), a series of processes will be complete | finished.

  In the above description, the parking area that can be parked is determined as the priority area in order from the parking area closest to the shortest communication path. However, the present invention is not limited to this. Based on the travel history of other mobiles that share the same, a parking area with a higher number of parking histories may be determined as a priority area with a higher priority, or a parking area with more vacant parking spaces, You may determine as a priority area with a high priority.

(An example in which the parking floor of the three-dimensional parking lot 1300 is a parking area)
Next, an example in which the parking floor of the three-dimensional parking lot 1300 is set as a parking area will be described with reference to FIG. FIG. 13 is an explanatory diagram illustrating an example in which the parking floor of the multistory parking lot 1300 is set as a parking area.

  In FIG. 13, a multi-storey parking lot 1300 is additionally provided in the complex facility 1310. The complex facility 1310 and the multi-story parking lot 1300 have five stories. Each floor of the complex facility 1310 is provided with a communication path (not shown) that communicates with each floor of the multilevel parking garage 1300. It is assumed that the complex facility 1310 has a plurality of stores. Reference numeral 1320 denotes the current position.

  Each floor of the multi-story parking lot 1300 is the parking area described above. Assuming that the store located on the third floor is set as the destination in the complex facility 1310 equipped with such a multistory parking lot 1300, as shown in the flowcharts described above, 3 The floor parking lot 1301 is guided as a priority area. In this way, when a store entering a complex facility or the like is set as a destination, it is possible to guide a parking area in the vicinity of the connection path closest to the store. Moreover, although it is difficult for the user to determine a convenient parking area (number of parking floors) by the user himself / herself in the multi-story parking lot as compared with the flat parking lot, as described above, the navigation apparatus 300 allows the number of parking floors to be determined. Is determined as the priority area, it is possible to easily reach a highly convenient parking area and to park the vehicle.

(An example of the parking area in the 3rd floor parking lot 1301 of the multi-story parking lot 1300)
Next, an example of a parking area in the third-floor parking lot 1301 of the multi-story parking lot 1300 will be described with reference to FIG. FIG. 14 is an explanatory diagram illustrating an example of a parking area of the third-floor parking lot 1301 in the multi-story parking lot 1300. In FIG. 14, as shown in FIG. 13, a case will be described in which each floor is not a parking area but a predetermined area on each floor is a parking area.

  The 3rd floor parking lot 1301 of the three-dimensional parking lot 1300 has parking areas 1411 to 1413 in which the parking space 1401 is partitioned for each predetermined number. Of the third-floor parking lot 1301, the parking areas 1411 to 1413 that can be parked in the parking space 1401 are determined as priority areas with high priority in the order of the parking areas 1411 to 1413 that are close to the communication path with the facility.

  Assuming that the store located on the third floor is set as the destination in the complex facility 1310 equipped with such a multi-story parking lot 1300, as shown in the flowchart of FIG. The parking area 1411 of the third floor parking lot 1301 is guided as a priority area with a high priority. In addition, when the information on the empty vehicle state for each parking space can be acquired, as shown by reference numeral 1420, the display may be performed on the empty parking space closest to the connection path in the priority area.

  In the above description, it is assumed that each floor of the complex facility 1310 is provided with a communication path that communicates with each floor of the multilevel parking garage 1300. For example, the communication path is provided only on the first floor. If there is, the priority area may be determined in preference to the parking area closest to the first-floor connecting road. Moreover, when the elevator is provided in the multilevel parking garage in which the communication path is provided only on the first floor, for example, the priority areas may be determined in the order of the parking areas near the elevators and stairs on each floor.

(Example of parking area in underground parking lot 1500)
Next, an example of a parking area in the underground parking lot 1500 will be described with reference to FIG. FIG. 15 is an explanatory diagram showing an example of a parking area in the underground parking lot 1500.

  In the underground parking lot 1500 shown in FIG. 15, there are parking areas 1511 to 1513 in which the parking space 1501 is divided into predetermined numbers in B1F which is the first basement. Similarly, B2F, which is the second basement floor, has parking areas 1521 to 1523 in which parking spaces 1501 are divided into predetermined numbers. In addition, this underground parking lot 1500 is provided with an elevator 1530 as a communication path that communicates with the ground. In addition, it is assumed that the communication path to the facility exists on the first floor above the ground.

  If a facility associated with such an underground parking lot 1500 is set as a destination, the vehicle is guided to B1F of the underground parking lot 1500 as shown in the flowchart of FIG. And it determines as a priority area with a high priority in order of the parking areas 1511-1513 near the elevator 1530, and 1521-1523 of B2F. Thus, a more detailed priority area can be guided by setting the parking area as a predetermined area on each floor. In addition to the determination of the priority area, for example, a parking area close to the elevator 1530 may be determined as the priority area based on the condition that the priority area is close to the elevator 1530 on each floor. As a specific priority, the parking area 1511 close to the B1F elevator 1530 may have the highest priority, and then set to the parking area 1521 close to the B2F elevator 1530.

  As described above, the navigation device 300 according to the second embodiment determines a parking area that is closer to a communication path as a priority area with higher priority, and performs guidance to the priority area in descending order of priority. did. According to such a configuration, the user can park in the parking area close to the communication path with the feature. Therefore, for example, it is possible to minimize the occurrence of unnecessary time for moving from the parking position to the target feature despite the early arrival at the parking lot.

  Moreover, in Example 2, based on the congestion information for every parking area, the parking area which can be parked in order from the parking area close to the connecting road is determined as a priority area with high priority. According to such a configuration, the user can park in the parking area close to the communication path according to the congestion state. Therefore, it is possible to prevent unnecessary time for searching for a parking position.

  Moreover, in Example 1 and Example 2, it is related with the number of times of the parking history in the parking area of the said parking lot based on the information of parking area, the driving history of the other moving body which shares driving data, and the parking history set Based on the conditions, a parking area with a higher number of parking histories may be determined as a priority area with higher priority. According to such a configuration, for example, the priority area can be determined based on the statistics of the parking history of other mobile objects that frequently use the parking lot, so that a parking area that is convenient for the user can be determined. It can be a priority area.

  Moreover, in Example 1 and Example 2, based on the information on parking area, the empty vehicle information which shows the empty state for every parking area, and the conditions regarding the empty state to be set, the more empty parking area, the higher the priority. May be determined as a high priority area. According to such a structure, the said parking area can be guided as a priority area with respect to the beginner and the user who desires the parking area which is not crowded.

  Moreover, in Example 1 and Example 2, as information on a parking area, information including information on a route in the priority area is acquired, and a route to the priority area is determined based on the information on the route. . According to such a configuration, it is possible to guide to the destination with the priority area as the destination.

  In the first and second embodiments, when the destination is set, the priority area is determined from the parking lots set in advance in association with the destination. According to such a configuration, when a facility or the like is set as a destination, a parking lot associated with the facility can be searched as a destination, and a priority area of the parking lot can be determined.

  In the second embodiment, when there are a plurality of stores in the complex facility, and there are a plurality of communication paths (entrances / entrances) for contacting a parking lot set in advance in association with the complex facility, When one of the stores is set as the destination, the shortest connecting route is selected from the multiple connecting routes based on the location information of the store and the connecting route, and the shortest of the parking lots is selected. The parking area closer to the connecting road is determined as a priority area with higher priority. According to such a configuration, even when there are a plurality of entrances / exits, the user can park in a parking area near the shortest connection path.

  Further, in the second embodiment, when there are a plurality of parking lots, a plurality of communication paths based on the position information of the store, the position information of the plurality of parking lots, and the position information of the plurality of communication paths (entrances / exits). In addition to selecting the shortest communication path from among the parking lots, a parking lot close to the shortest connection path is selected from a plurality of parking lots, and among the selected parking lots, the parking area closest to the shortest connection path has a higher priority. It was decided as a priority area. According to such a configuration, even when there are a plurality of parking lots, the user can park in the parking area of the parking lot close to the entrance / exit.

  Moreover, in Example 2, the case where the parking lot was a three-dimensional parking lot and the parking area was the parking floor of the three-dimensional parking lot was described. Although it is difficult for a user to determine a convenient parking area (number of parking floors) by himself / herself in a multi-story parking lot as compared to a flat parking lot, the navigation apparatus 300 gives priority to the parking floor number as described above. By determining the area, it is possible to easily reach a convenient parking floor and to park the vehicle. Moreover, although the case where the parking area was set as the predetermined area on each floor was described, by adopting such a system, a more detailed priority area can be guided.

  Example 3 of the present invention will be described below. In the third embodiment, a communication navigation system is used. In the third embodiment, the description of the same configuration as that of the first and second embodiments will be omitted as appropriate.
