Abstract
A failure determination device includes an acquirer to acquire pressure values of air springs provided to bogies included in a vehicle to support a vehicle body included in the vehicle, a compensator to perform compensation of the pressure values of the air springs depending on the position of the vehicle, and a determiner to determine, based on the pressure values of the air springs compensated by the compensator, whether any failure occurs in the air springs.
Claims18
A failure determination device comprising:
- acquiring circuitry to acquire pressure values of air springs from pressure sensors, the air springs being provided to a bogie included in a vehicle to support a vehicle body included in the vehicle, the pressure values being values measured by the pressure sensors, the pressure sensors measuring pressures of air inside the air springs;
- compensating circuitry to perform, depending on a position of the vehicle, compensation of the pressure values of the air springs acquired by the acquiring circuitry;
- and
- determining circuitry to determine, based on the pressure values of the air springs compensated by the compensating circuitry, whether any failure occurs in the air springs.

A method for determining a failure, the method comprising:
- performing, depending on a position of a vehicle, compensation of pressure values of air springs received from pressure sensors to measure pressures of air inside the air springs, the air springs being provided to a bogie included in the vehicle and supporting a vehicle body included in the vehicle, the pressure values of the air springs being values measured by the pressure sensors;
- and
- determining, based on the compensated pressure values of the air springs, whether any failure occurs in the air springs.
