Title:
燃料タンクシステム
Document Type and Number:
Japanese Patent JP5743113
Kind Code:
B2
Abstract:
A first pressure sensor that detects pressure in a narrow pressure range with high accuracy is provided in a fuel tank, and a second pressure sensor that detects pressure in a wide pressure range with low accuracy with respect to the first pressure sensor is provided in vapor piping between the fuel tank and a tank blocking valve. Until internal pressure of the fuel tank becomes a second predetermined pressure, meter indication is performed on a display on the basis of a second tank internal pressure P2 calculated by the second pressure sensor and an atmospheric pressure sensor, and when internal pressure of the fuel tank becomes less than the second predetermined pressure, the meter indication is performed on the display on the basis of a first tank internal pressure P1 obtained by the first pressure sensor until internal pressure of the fuel tank becomes a fifth predetermined pressure.
