ABSTRACT:
This invention relates to a superior suppressing of vibration in a car body when a vehicle runs on a straight railroad and a curvilinear railroad. The invention is comprised of a fluid pressure-acting mechanism arranged between the car body and the truck along with springs for positively controlling a force acting between the car body and the truck with the supplied pressure fluid, an acceleration detector for detecting an acceleration of the car body, and means for determining a displacement generated relatively between the car body and the truck under a steady acceleration acting against the car body. The invention further comprises a controller for receiving a vibration suppressing control signal as a control input representing a result of detection of the acceleration detector, and for receiving a value corresponding to a relative displacement between the car body and the truck contained in the vibration suppressing control signal as a result of the determination from the means for determining a relative displacement between the car body and the truck. The controller subtracts this value from the vibration suppressing controlling signal and outputs it as a control signal. The invention further includes a fluid control unit for controlling a fluid pressure to be supplied to the fluid pressure-acting mechanism with a control signal output by the controller, wherein vibration caused by a relative displacement generated between the car body and the truck with a steady acceleration acting against the car body can be presented to improve driving comfort.
