Gas filling system and vehicle

A gas filling system comprising:

• a vehicle that includes a receptacle, multiple tanks and a first communication instrument, the multiple tanks being able to contain high-pressure gas and including a first tank and a second tank;
• and
• a gas station that includes a nozzle, a controller that is configured to control spray of the nozzle and a second communication instrument that receives a signal that is transmitted from the first communication instrument, and that feeds the gas to the multiple tanks, wherein
• the vehicle includes
• a first temperature sensor that acquires temperature information of the gas stored in a body portion of the first tank;
• a second temperature sensor that acquires temperature information of the gas stored in a body portion of the second tank;
• and
• a controller that includes a CPU, a ROM, a RAM, and a determination unit, the controller is configured to:
• calculate a difference between an indicated value of the first temperature sensor and an indicated value of the second temperature sensor;
• determine whether the absolute value of the difference is larger than a predetermined value;
• estimate a drift amount of the first temperature sensor on the condition that the absolute value of the difference is larger than the predetermined value;
• correct the temperature information of the first temperature sensor by using the estimated drift amount;
• permit transmission of the temperature information, acquired by the first temperature sensor, from the first communication instrument to the second communication instrument on the condition that the absolute value of the difference is smaller than or equal to the predetermined value and the determination unit permits the gas station to carry out communication fueling,
• wherein carrying out communication fueling means the controller in the vehicle and the controller in the station start the process of charging the high pressure gas to the tank through the nozzle and the receptacle while carrying out communication via the communication instrument of the vehicle and the communication instrument in the station,
• wherein the determination unit prohibits transmission of the temperature information, acquired by the first temperature sensor, from the first communication instrument to the second communication instrument on the condition that the absolute value of the difference is larger than the predetermined value, and
• wherein the determination unit permits transmission of the corrected temperature information, from the first communication instrument to the second communication instrument even when the absolute value of the difference is larger than the predetermined value.

A vehicle comprising:

• a first communication instrument;
• a receptacle;
• a tank that is able to contain high-pressure gas that is supplied from a gas station including a nozzle, a controller that is configured to control spray of the nozzle and a second communication instrument that receives a signal from the first communication instrument, the tank being constituted by single or multiple tanks;
• a first temperature sensor that acquires temperature information of the gas stored in a body portion of the tank;
• a second temperature sensor that acquires temperature information outside the body portion of the tank;
• a controller that includes a CPU, a ROM, a RAM, and a determination unit, the controller is configured to:
• calculate a difference between an indicated value of the first temperature sensor and an indicated value of the second temperature sensor;
• determine whether the absolute value of the difference is larger than a predetermined value;
• permit transmission of the temperature information, acquired by the first temperature sensor, from the first communication instrument to the second communication instrument on the condition that the absolute value of the difference is smaller than or equal to the predetermined value and the determination unit permits the gas station to carry out communication fueling, and
• wherein carrying out communication fueling means the controller in the vehicle and the controller in the station start the process of charging the high pressure gas to the tank through the nozzle and the receptacle while carrying out communication via the communication instrument of the vehicle and the communication instrument in the station,
• wherein the determination unit prohibits transmission of the temperature information, acquired by the first temperature sensor, from the first communication instrument to the second communication instrument on the condition that the absolute value of the difference is larger than the predetermined value, and
• wherein the second temperature sensor is provided at a position in a valve connected to one end of the body portion of the one of the tanks, where the second temperature sensor is outside a passage in the valve through which the gas flows.
