Abstract

To acquire information on the refueling position when a vehicle is refueled. A SO 2 sensor detects the concentration of sulfur dioxide in the exhaust gas of the internal combustion engine after refueling. Region-by-region concentration information that associates refueling position information with information obtained by averaging sulfur dioxide concentration is transmitted to the data center. As a result, it is possible to accumulate information reflecting the properties of fuel distributed in each area in real time in the data center.

First claim

What is claimed is:

1 . An information communication device of a vehicle, the information communication device that is mounted on a vehicle including an internal combustion engine as a driving force source for traveling, and transmits information to an information management server, the information communication device comprising:
a refueling detection unit for detecting that the vehicle has been refueled; a refueling position information acquisition unit for acquiring refueling position information that is information on a vehicle position when the refueling detection unit detects that the vehicle has been refueled; a concentration detection unit for detecting concentration of sulfur dioxide in an exhaust gas of the internal combustion engine after the vehicle has been refueled; and an information transmission unit for transmitting, to the information management server, concentration information for each region in which the refueling position information acquired by the refueling position information acquisition unit is associated with concentration information of the sulfur dioxide detected by the concentration detection unit or concentration analysis information of the sulfur dioxide obtained from the information.

2 . The information communication device according to claim 1 , wherein the concentration analysis information of the sulfur dioxide is information obtained by averaging the concentration of the sulfur dioxide detected during a period from when the vehicle has been refueled to when the vehicle is refueled next time.

3 . An information management server that receives concentration information for each region from the information communication device according to claim 1 , the information management server comprising a storage unit for generating and storing information on a sulfur content of fuel distributed for each region based on the received concentration information for each region.

4 . An information communication system that is constructed by a plurality of the vehicles each equipped with an information communication device and an information management server;
the information communication device is mounted on a vehicle including an internal combustion engine as a driving force source for traveling, and transmits information to the information management server, the information communication device comprises (i) a refueling detection unit for detecting that the vehicle has been refueled; (ii) a refueling position information acquisition unit for acquiring refueling position information that is information on a vehicle position when the refueling detection unit detects that the vehicle has been refueled; (iii) a concentration detection unit for detecting concentration of sulfur dioxide in an exhaust gas of the internal combustion engine after the vehicle has been refueled; and (iv) an information transmission unit for transmitting, to the information management server, concentration information for each region in which the refueling position information acquired by the refueling position information acquisition unit is associated with concentration information of the sulfur dioxide detected by the concentration detection unit or concentration analysis information of the sulfur dioxide obtained from the information; the information management server receives concentration information for each region from the information communication device, the information management server comprises a storage unit for generating and storing information on a sulfur content of fuel distributed for each region based on the received concentration information for each region; and the information management server receives and stores the concentration information for each region from each of the vehicles via a communication network.
