VEHICLE BODY INCLINATION CONTROL SYSTEM AND VEHICLE BODY INCLINATION CONTROL METHOD FOR RAILWAY VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for vehicle body inclination control that improve ride comfort of a railway vehicle.SOLUTION: A vehicle body inclination control system includes: a first curve detection unit 23 which detects a curve of a track on the basis of track information data; a first command value calculation unit 24 which calculates a first inclination angle command value at which a vehicle body has a target inclination angle when travelling on the curve detected by the first curve detection unit 23; a second curve detection unit 25 which detects a curve of the track on the basis of travel speed and turning angular velocity of the railway vehicle; a second command value calculation unit 26 which calculates a second inclination angle command value at which lateral acceleration of the vehicle body approaches zero when travelling on the curve detected by the second curve detection unit 25; a determination unit 27 which determines that a detection result by the first curve detection unit 23 is erroneous, in the case that a curve is detected by the second curve detection unit 25 in a curve-undetected interval according to the first curve detection unit 23; and an inclination control unit 28 which controls a pneumatic spring such that the vehicle body is inclined on the basis of the second inclination angle command value, in the case that the above detection result is determined to be erroneous by the determination unit 27.
