In-vehicle device, information distribution server, and facility information display method

Abstract

An in-vehicle device 1 regularly transmits to an information distribution server 2 an acquisition request that includes an own vehicle position and a facility search condition, and acquires facility information matching the condition around the vehicle. The in-vehicle device 1 controls the number of displays of the facility information on the basis of the information in an in-vehicle sensor group 12 when displaying the acquired facility information on a map.

1 . An information distribution server that causes an in-vehicle device to display facility information on a facility, the server comprising:
 a facility information database that stores the facility information;   a facility information searcher that extracts, on the basis of a position of a vehicle on which the in-vehicle device is mounted and a facility search condition, the facility information on the facility located around the vehicle and matching the facility search condition from the facility information database;   a facility information generation processor that converts the facility information extracted by the facility information searcher into a data format for display by the in-vehicle device, and that controls the number of displays of the facility information on the basis of vehicle information that includes at least one of a speed of the vehicle and presence or absence of an obstacle around the vehicle in addition to the position of the vehicle; and   a facility information transmitter that receives an acquisition request that includes the vehicle information and the facility search condition from the in-vehicle device, and that returns the facility information in the data format generated by the facility information generation processor.   
     
     
         2 . The information distribution server according to  claim 1 , further comprising:
 a facility information updating section that receives, from the in-vehicle device, information that indicates whether or not the vehicle is in a parking state in a parking lot attached to the facility, and updates a parking lot use status of the facility managed as the facility information by the facility information database.   
     
     
         3 . The information distribution server according to  claim 1 , further comprising:
 an external server searcher that extracts, from an external content provider group, the facility information on the facility located around the vehicle and matching the facility search condition; and   a facility information converter that, when converting the facility information extracted by the external server searcher into the data format that is the same as the data format in the facility information generation processor, converts the facility information into the information from a viewpoint of the vehicle.
