Abstract
A railway vehicle body tilting system has a height control valve for supplying and discharging compressed air to and from an air spring by an actuator, an auxiliary control valve for supplying compressed air to the air spring and thereby causing a car body to tilt, a backup valve for switching the connection between the air spring and either the height control valve or the auxiliary control valve, and a controller installed in each of vehicles linked together as a train. During normal operation, the controller provided in each of the cars controls the height control valve of the respective car and monitors for faulty operation in other linked controllers. If a fault arises in a linked controller, control over the malfunctioning controller is terminated, and another normal controller controls a backup valve in the car with the malfunctioning control device.
