For example, when the voice of a child is recognized in the vehicle as a situation in the vehicle, it is determined that the characteristic of the passenger is "child-to-child". In addition, when an application program for a pregnant woman is installed as the use status of the communication terminal 6, it is determined that the characteristic of the occupant is "pregnant".

  In the case where the same occupant corresponds to a plurality of conditions, it is desirable to prioritize two items of "the current situation in the vehicle" and the "use status of the communication terminal 6" basically. For example, when an application program for a pregnant woman is installed in the communication terminal 6 of the occupant and the walking speed is detected to be lower than a threshold value by the gyro sensor, it corresponds to two characteristics of "pregnant" and "elderly person" However, it is desirable to judge it as "pregnant".

  Further, in order to determine the current characteristics of the occupant of the vehicle, in the determination processing of S31, among the information stored in the collected information DB 12, the latest information collected within a predetermined period in the past from the current time (for example within the past one week) It is desirable to use

  Thereafter, in S32, the CPU 21 updates the occupant characteristic DB 13 based on the determination result of S31. As shown in FIG. 4, the occupant characteristic DB 13 corresponds to any of “pregnant”, “caregiver requiring care”, “children”, “elderly person”, “driving novice” and “general” for each occupant of the vehicle 4 Is stored.

  Next, a parking assistance processing program executed in the server device 3 and the navigation device 5 constituting the parking assistance system 1 according to the present embodiment will be described based on FIG. FIG. 12 is a flowchart of a parking assistance processing program according to the present embodiment. Here, the parking assistance processing program is executed after the ACC power supply (accessory power supply) of the vehicle 4 is turned on, and is a program for guiding a parking space suitable for the occupants of the vehicle.

First, a parking assistance processing program executed in the navigation device 5 will be described.
In S41, the CPU 51 determines, based on the current position of the vehicle detected by the current position detection unit 31 and the map information, whether the vehicle has entered any parking lot. In addition, you may determine the approach to a parking lot based on the captured image imaged with the camera installed in the vehicle.

  Then, when it is determined that the vehicle has entered into any parking lot (S41: YES), the process proceeds to S42. On the other hand, when it is determined that the vehicle has not entered the parking lot (S41: NO), the parking assistance processing program is ended.

  In S42, the CPU 51 transmits an information request instruction instructing the server device 3 to request information on the parking space. The information request instruction includes an ID for identifying an occupant of a vehicle in which the navigation device 5 is installed, and an ID for identifying a parking lot into which the vehicle has entered. Thereafter, in the server device 3 which receives the information request instruction from the navigation device 5 as described later, sorting and distribution of a parking space recommended for parking by the vehicle occupant are performed (S52 to S56).

  Subsequently, in S43, the CPU 51 receives the information distributed from the server device 3 in response to the transmission of the information request instruction signal. The information received in S43 is information for instructing a vehicle occupant of a parking space to be recommended to be parked, and more specifically, a parking space that is currently idle and corresponds to the characteristics of the vehicle occupant. is there. The number of parking spaces to be instructed may be only one, or two or more. The corresponding parking space is specified by the server device 3 in the process of S52 to S55 described later.

  Thereafter, in S44, the CPU 51 outputs the guidance information for guiding the parking space received in S43 using the liquid crystal display 35 and the speaker 36. For example, FIG. 13 is a view showing a parking space guidance screen 61 displayed on the liquid crystal display 35 as an example of parking space guidance information outputted by the navigation device 5 at S44.

  As shown in FIG. 13, the parking space guide screen 61 displays an overall view 62 of the parking lot, a vehicle position mark 63 indicating the current position of the vehicle, and an identification mark 64 identifying the parking space recommended for parking. Be done. As a result, the vehicle occupant can easily grasp the parking position to be parked of the vehicle by visually recognizing the parking space guidance screen 61. The guidance of the parking space may be voice guidance.

  Furthermore, as means for parking assistance, vehicle control may be performed other than the guidance of the parking space described above. For example, when the present invention is applied to a vehicle that performs automatic driving in which part or all of the travel control of the vehicle is performed on the vehicle side, the automatic driving to the corresponding parking space may be assisted. .

Next, a parking assistance processing program executed in the server device 3 will be described.
First, in S51, the CPU 21 determines whether or not there is transmission of an information request instruction instructing a request for information related to a parking space from each vehicle 4 traveling the whole country.

  When it is determined that the information request instruction has been transmitted (S51: YES), the information request instruction to be transmitted is received (S52). The information request instruction signal includes an ID for identifying an occupant of a vehicle in which the navigation device 5 is installed, and an ID for identifying a parking lot into which the vehicle has entered.

  On the other hand, when it is determined that there is no transmission of the information request instruction (S51: NO), the parking assistance processing program is ended.

  In S53, the CPU 21 refers to the occupant characteristic DB 13 and specifies the characteristic of the occupant of the vehicle of the transmission source from the occupant ID included in the information request instruction. The characteristics of the occupants of the vehicle are specified by any of "pregnant", "caregiver requiring care", "child with children", "elderly person", "driving beginner" and "general". The occupant whose characteristic is not stored in the occupant characteristic DB 13 is "general".

  Next, in S54, the CPU 21 refers to the parking lot DB 14 and extracts, from the parking lot ID included in the information request instruction, information on the parking lot to which the driver of the vehicle of the transmission source has entered. Specifically, information on the structure of the parking lot and the availability of the parking space is extracted.

  Thereafter, in S55, the CPU 21 specifies a parking space (hereinafter referred to as a corresponding parking space) which recommends parking for the passenger of the vehicle of the transmission source of the information request instruction. Specifically, a parking space that is currently free and that corresponds to the characteristics of the vehicle occupant is identified as the corresponding parking space.

Here, the parking space corresponding to the characteristics of the occupant of the vehicle is, for example, a parking space corresponding to the following conditions (1) to (3).
(1) "pregnant""careerneeding""elderlyperson" ... parking space is as large as possible. In the case of a parking lot attached to the facility, the walking distance to the facility entrance is as short as possible.
(2) "Children", "Driving beginners" ... A parking space in which other vehicles are not parked as much as possible.
(3) "General" ··· · · · · · If the parking lot attached to the facility, the walking distance to the facility entrance is as short as possible.

  The parking space specified under the above conditions (1) to (3) is a parking space that corresponds to the preference for parking of the vehicle occupant. For example, for "pregnant woman", "caregiver requiring care" and "elderly person", it is possible to get on and off with ease, and it becomes a parking space where the walking distance is as short as possible. For example, for "child-friendly" and "driving beginners", the parking space can be easily operated for parking or secure for children.

  In addition, when there is no parking space applicable to (1)-(3) among the parking spaces in an idle state, let the parking space closest to conditions be a corresponding | compatible parking space. Alternatively, it may be determined that there is no corresponding parking space. In that case, it is answered that there is no parking space recommended for parking for the vehicle that has sent the information request instruction.

  In addition, when a plurality of parking spaces correspond to the above (1) to (3), only the parking space under the best condition may be specified as the corresponding parking space, or all the parking spaces corresponding to the conditions may be specified. It may be specified as a corresponding parking space.

  Thereafter, in S56, the CPU 21 distributes the information on the corresponding parking space identified in S55 to the navigation device 5 of the request source. Thereafter, the guidance information of the corresponding parking space distributed in the navigation device 5 is output (S44).

  In addition, in the navigation apparatus 5 instead of the server apparatus 3, the processes of S52 to S55 may be executed. In that case, the collection information DB 12, the occupant characteristic DB 13 and the parking lot DB 14 are distributed from the server device 3 to the navigation device 5. In addition, the occupant characteristic specification processing program (FIG. 10) may be executed by the navigation device 5 as well.

  As described above in detail, in the parking assistance system 1 and the server device 3 according to the present embodiment, the current condition in the vehicle to be parked and the use condition of the communication terminal possessed by the occupant of the vehicle to be parked are acquired (S2, S12) The characteristics of the occupant of the vehicle are specified based on the acquired information (S31). Then, among the parking spaces provided in the parking lot where the vehicle parks, the parking space corresponding to the identified occupant's characteristic is specified (S55), and the specified parking space is guided (S44). By specifying the characteristics of the occupant of the vehicle from the current situation inside or the use situation of the communication terminal possessed by the occupant, it is possible to accurately grasp the preference concerning the parking of the occupant of the current vehicle. As a result, it is possible to support parking in a more appropriate parking space.
