  If navigation ECU10 acquires search conditions, such as a genre and an address which a user designates by touch panel operation etc., index 18b of search data 18 will search for facilities applicable to search conditions. Then, the detected facilities and the like are displayed on the touch panel display 15 as a list. The user selects one facility from the list and sets the destination.

In addition, the navigation ECU 10 transmits and receives data to and from the transceiver 6 installed in the vicinity of the road using the communication interface 19.
Next, the configuration of the parking lot guidance server 3 will be described with reference to FIG. The parking lot guidance server 3 includes a CPU 30, a RAM 31, a ROM 32, a communication I / F 33, a registration data storage unit 34, and a facility data storage unit 36. The CPU 30 uses the RAM 31 as a work area and performs various processes using a parking lot guidance program stored in the RAM 31 or the ROM 32. Moreover, various data are transmitted / received with the parking lot management server 2 and the navigation apparatus 5 using communication I / F33. The CPU 30 corresponds to the number acquisition means, the destination acquisition means, the parking lot search means, the empty vehicle frame number acquisition means, the arrival point setting means, the output control means, and the guidance control means.

  The registration data storage unit 34 stores registration data 37 registered in advance by a user (representative user) who performs setting such as member designation among members constituting the group. As shown in FIG. 6A, the registration data 37 includes the ID (navigation ID) 37a of the navigation device 5 owned by the representative user, the destination 37b transmitted from the navigation device 5, and the vehicle C of the member constituting the group. The identification data (other vehicle identification data) 37c and the like of the navigation device 5 mounted on the vehicle are stored. The destination 37b and the other vehicle identification data 37c are data stored when the data is transmitted from the navigation device 5, and are set to “Null” or the like when the data is not received. ing. The other vehicle identification data 37c stores a navigation ID of the navigation device 5 mounted on the other vehicle, an e-mail address that can be used by the navigation device 5 of the other vehicle, or the like. The destination 37b and the other vehicle identification data 37c may be transmitted in advance from another terminal owned by the representative user.

  Facility data 38 is stored in the facility data storage unit 36. The facility data 38 is data relating to each facility, and stores a facility name 38a, an index 38b used for search, parking lot data 38c, and coordinate data 38d. The parking lot data 38c is data indicating whether or not there is a parking lot at the facility indicated by the facility data 38. When there is a parking lot, the management number of the parking lot, the name of the parking lot, the coordinates of the parking lot, and the like are further stored. The coordinate data 38d indicates the position of the facility.

  Next, the processing procedure of this embodiment is demonstrated according to FIG.7 and FIG.8. In the present embodiment, the representative user performs settings such as designation of the destination and the vehicle C using the navigation device 5 owned by the representative user.

  The navigation ECU 10 of the navigation device 5 owned by the member of the representative user waits for the start of guidance for the group (step S1). At this time, when a predetermined touch panel operation for starting guidance is performed on the setting screen displayed on the touch panel display 15 or an operation switch 22 provided near the screen for starting guidance is pressed. Then, it is determined that guidance is to be started (YES in step S1).

  Next, the representative user performs a genre search, an address search, etc. according to the screen of the touch panel display 15, and inputs a destination. By this operation, the navigation ECU 10 acquires the destination (step S2), and transmits data indicating the destination to the parking lot guidance server 3 via the transceiver 6 and the network N2, together with the navigation ID 37a that is the identifier of the device. (Step S3). When receiving the navigation ID 37a and the destination data, the parking lot guidance server 3 stores the destination in the registration data 37 corresponding to the received navigation ID 37a (step S4).

  Next, the representative user specifies all the vehicles C on which the members constituting the group get on according to the screen of the touch panel display 15. The data related to the member's vehicle C is registered in advance in the navigation device 5 of the own vehicle in association with the name of each member and other vehicle identification data 37c for identifying the navigation device 5 of the member. Then, from among the registered vehicles C, the member vehicles C to be gathered this time are selected. Or you may make it memorize | store the address book owned by the representative user or group which memorize | stored the data regarding each member in the parking lot guidance server 3, call this address book, and select the vehicle C. FIG.

  When the vehicle C constituting the group is designated, the navigation ECU 10 acquires the other vehicle identification data 37c from, for example, a built-in memory (step S5). When the other vehicle identification data 37c is acquired, the navigation ECU 10 transmits the other vehicle identification data 37c to the parking lot guidance server 3 (step S6). When the parking lot guidance server 3 receives the other vehicle identification data 37c, the parking lot guidance server 3 stores the other vehicle identification data 37c and the like in the registration data 37 corresponding to the navigation device 5 as the transmission source (step S7). Note that if the other vehicle identification data 37c is stored in advance by another terminal used by the representative user, steps S6 to S7 are omitted. Further, the vehicle C may be specified before the destination is specified.

  Thus, when the parking lot guidance server 3 receives the destination or the like, it performs a parking lot search process (step S8). This parking lot search process will be described with reference to FIG. The CPU 30 of the parking lot guidance server 3 calculates the number of other vehicle identification data 37c stored in the registration data 37 corresponding to the representative user, and acquires the number of collectives heading to the destination (step S8-1). Further, the destination is acquired from the registration data 37 (step S8-2). Note that the representative number may be manually input to the navigation device 5 by the representative user.

  Furthermore, based on the acquired destination, the CPU 30 acquires the number of empty frames in the parking lot attached to the destination (step S8-3). Specifically, the CPU 30 searches the facility data storage unit 36 and extracts facility data 38 corresponding to the designated destination. Further, based on the parking lot data 38c included in the extracted facility data 38, it is determined whether or not a parking lot is attached to the destination. When there is a parking lot attached to the destination, a transmission request for the number of empty vehicle frames is made to the parking lot management server 2 that manages the vacant state of the parking lot. When receiving the transmission request, the parking lot management server 2 transmits the number of empty vehicle frames at that time to the parking lot guidance server 3.

  The CPU 30 of the parking lot guidance server 3 compares the number of empty vehicle frames received from the parking lot management server 2 with the number of collectives acquired in step S7-1, and vehicles C corresponding to the collective quantity can park in the parking lot. Is determined (step S8-4). If it is determined that the number of empty vehicle frames is equal to or greater than the number of collective vehicles and that the number of vehicles C can be parked (YES in step S8-4), the parking lot is set to the vehicle arrival position where the vehicles C gather. (Step S8-5).

On the other hand, if it is determined in step S8-4 that the number of empty frames in the parking lot is less than the set number and the number of vehicles C in the set number is determined to be unparkable (NO in step S8-4), the parking lot The CPU 30 of the guidance server 3 searches for a parking lot around the destination (step S8-6). Here, the CPU 30 may search for one parking lot in which all the sets can be parked, or may search for a plurality of parking lots for parking each vehicle separately. If each vehicle can be parked separately in different parking lots, the remaining number can be calculated by subtracting the number of empty parking spaces at the parking lot attached to the destination from the number of units. Search for other parking lots. Even when the parking lot attached to the destination is not detected in step S8-3, the process proceeds to step S8-6 to search for a parking lot around the destination.

  When searching for a parking lot around the destination, the CPU 30 of the parking lot guidance server 3 uses the facility data 38 to search for a parking lot within a predetermined distance (for example, 300 m) around the destination. For example, among the data whose index 38b is “parking lot”, the data whose coordinate data 38d is close to the destination is searched. Then, one parking lot around the destination is extracted. At this time, for example, a parking lot closest to the destination may be extracted, or data determined to be applicable first may be extracted.

  The CPU 30 of the parking lot guidance server 3 determines whether one parking lot around the destination has been detected (step S8-7). If a parking lot around the destination is not detected (NO in step S8-7), the process proceeds to step S9 shown in FIG.

  When a parking lot around the destination is detected (YES in step S8-7), the CPU 30 of the parking lot guidance server 3 transmits the number of empty vehicles to the parking lot management server 2 corresponding to the extracted one parking lot. A request is transmitted and the number of empty vehicle frames is acquired from the parking lot management server 2 (step S8-8).

  When the number of empty vehicle frames is acquired, the CPU 30 of the parking lot guidance server 3 determines whether or not the detection of empty vehicle frames for the number of collectives has been completed (step S8-9). When the CPU 30 is searching for a parking lot that can park all the number of aggregates, the CPU 30 determines whether or not a parking lot having an empty vehicle frame number equal to or greater than the aggregate number is detected. When the parking lot where each vehicle C is parked may be divided, it is determined whether or not an empty vehicle frame corresponding to the number of sets has been detected across a plurality of parking lots. At this time, for example, it is determined whether or not the total sum of the empty vehicle frames included in each extracted parking lot is equal to or greater than the number of aggregates. Alternatively, the number of empty vehicle frames acquired in step S8-8 is subtracted from the remaining number when some vehicles C are parked in the parking lot attached to the destination, and the updated remaining number is “0”. Determine whether or not.

  If the detection of empty vehicle frames for the number of sets has not been completed (NO in step S8-9), the process returns to step S8-6 to search for the next parking lot. If the next parking lot cannot be detected even after the search for the predetermined distance range from the destination is completed (NO in step S8-7), the process proceeds to step S9.

  In step S8-9, when the detection of empty vehicle frames for the number of sets is completed (YES in step S8-9), each parking lot in which an empty vehicle frame is detected is set as the vehicle arrival position (step S8-10). For example, when a parking lot around the destination where all the sets can be parked is detected, the parking lot is set as the vehicle arrival position. When the parking lot is divided by the vehicle C, a plurality of parking lots are set as the vehicle arrival positions of the vehicles C.

Thus, when the search for the parking lot is completed, the process proceeds to step S9 shown in FIG. 7, and the parking lot guidance server 3 searches the search result based on the navigation ID 37a and the other vehicle identification data 37c stored in the registration data 37. Is transmitted to the navigation device 5 of the representative user and each member. At this time, when one parking lot is set as the vehicle arrival position, the name or coordinate data of the parking lot is transmitted to each navigation device 5. When a plurality of parking lots are set as vehicle arrival positions, each parking lot is assigned to each vehicle C, and the name or coordinate data of the parking lot assigned to each vehicle C is assigned to each navigation device 5. Send. As a result of the search, if no empty vehicle frames for the set number are detected, data indicating non-detection is transmitted.

  When receiving the search result, the navigation device 5 determines whether or not the vehicle arrival position is set based on the search result (step S10). When one or a plurality of parking lots that can park the number of aggregated vehicles are set as vehicle arrival positions (YES in step S10), the process proceeds to step S11. If it is determined that a parking lot that can park the number of the aggregated vehicles has not been detected (NO in step S10), a screen indicating non-detection is displayed on touch panel display 15, and the process is terminated.

  In step S11, the navigation ECU 10 guides the vehicle arrival position. For example, the route data 16 is used to search for a route from the current position to the destination, and the searched route R is displayed on the map screen 15d as shown in FIG. For example, when the arrival position display button 15e displayed on the map screen 15d is operated, the navigation ECU 10 displays an arrival position guidance screen 15g around the destination as shown in FIG. On the arrival position guidance screen 15g, a destination index 15h and an arrival position index 15i are displayed. FIG. 10A shows a case where there is one parking lot set as the arrival position. Further, the arrival position guidance screen 15g may be displayed at another timing, for example, when the navigation device 5 receives the parking lot data that is the vehicle arrival position.

  When there are a plurality of parking lots set at the vehicle arrival position, as shown in FIG. 10 (b), in addition to the arrival position index 15i to which the host vehicle is heading, an arrival position index 15j to which the other car heads is displayed. It may be.

  The navigation ECU 10 of each navigation device 5 determines whether or not it has arrived at the vehicle arrival position while guiding the parking lot that is the vehicle arrival position, and determines whether or not the guidance has ended (step S12). When the user arrives at the meeting position or the guidance is interrupted by the user's operation, it is determined that the guidance is finished (YES in step S12), and the process is terminated.

  Moreover, since the empty frame of each parking lot always fluctuates, the parking lot guidance server 3 performs the arrival position selection process (S8) every predetermined time, and determines whether or not the initially set vehicle arrival position is changed. to decide. When the vehicle arrival position is changed, the parking lot data that becomes the new vehicle arrival position is transmitted to each navigation device 5. Each navigation device 5 receives parking lot data and provides guidance to the parking lot.
