INFORMATION PRESENTATION METHOD
An information presentation method incldues: acquiring full/vacancy information regarding a parking lot located at a facility set as a goal by a user; generating a route from a current location of a vehicle to the facility, based on road network data on a road from the current location of the vehicle to the facility; selecting, as a destination, a parking space based on parking lot network data on parking spaces and a roadway in the parking lot, and full/vacancy information indicating unoccupied parking spaces in the parking lot, and generating a route from an entrance of the parking lot to the selected parking space; and outputting guidance information for guiding the vehicle according to the generated routes, based on the current location of the vehicle both while reaching the facility from the current location and while reaching the destination from the entrance of the parking lot.
1 . An information presentation method executed in a navigation device that is able to communicate via a network with an information processing device having full/vacancy information indicating unoccupied parking spaces in a parking lot, and is configured to guide a vehicle to a destination by displaying guidance information for guiding the vehicle, the information presentation method comprising:
acquiring full/vacancy information regarding a parking lot located at a facility set as a goal by a user;
generating a route from a current location of the vehicle to the facility, based on road network data on a road from the current location of the vehicle to the facility;
selecting, as a destination, a parking space based on parking lot network data on parking spaces and a roadway in the parking lot, and the full/vacancy information, and generating a route from an entrance of the parking lot to the selected parking space; and
outputting guidance information for guiding the vehicle according to the generated routes, based on the current location of the vehicle form the navigation device both while reaching the facility from the current location and while reaching the destination from the entrance of the parking lot.
2 . The information presentation method according to claim 1 , wherein
the information processing device further has floor map data indicating a layout of spaces included in the facility, and
when a space planned to visit in the facility is selected by a user, the information presentation method acquires the floor map data from the information processing device and selects the parking space in accordance with the space planned to visit, further based on the floor map data.
3 . The information presentation method according to claim 2 , wherein when a plurality of spaces included in the facility are selected by a user as spaces planned to visit, the information presentation method extracts a specific space from the plurality of selected spaces, and selects the parking space close to the extracted space.
4 . The information presentation method according to claim 1 , wherein the information presentation method continuously acquires the full/vacancy information, and, when the selected parking space is no longer an unoccupied parking space in latest full/vacancy information, selects a parking space as a new destination, based on the latest full/vacancy information.
5 . The information presentation method according to claim 1 , wherein the information presentation method switches display so as to output the guidance information based on the road network data and own-vehicle location information indicating the current location of the vehicle while reaching the facility from the current location, and output the guidance information based on the parking lot network data and the own-vehicle location information while reaching the destination from the entrance of the parking lot.
6 . The information presentation method according to claim 1 , wherein the information presentation method identifies the current location of the vehicle, based on information acquired by an imaging device installed in the parking lot.
7 . The information presentation method according to claim 1 , wherein
the information processing device has the parking lot network data, and
when the facility is set as the goal by the user, the information presentation method acquires the parking lot network data of the parking lot located at the facility, form the information processing device.
8 . The information presentation method according to claim 1 , wherein
the navigation device has the parking lot network data, and
when the facility is set as the goal by the user, the information presentation method reads the parking lot network data in the navigation device.
9 . The information presentation method according to claim 1 , wherein the information presentation method outputs reservation information indicating the parking space selected as the destination, and causes the information processing device to process the selected parking space as a parking space that is not unoccupied in the full/vacancy information.
10 . The information presentation method according to claim 1 , wherein
the information processing device further has parking lot congestion information indicating a congestion situation of the roadway in the parking lot, and
the information presentation method acquires the parking lot congestion information, and generates the route from an entrance of the parking lot to the selected parking space, further based on the parking lot congestion information.
