A vehicle tilt control apparatus has an acceleration detector for detecting vibration in horizontal and lateral direction of a car body, a fluidically operating mechanism disposed between the car body and a truck and compensation circuits for compensating a centrifugal force component and a jolting component, respectively, of the output of the acceleration detector. The outputs of the compensation circuits are added and the resulting output is fed back to actuate a servo valve to control the fluidically operating mechanism. In this manner, the riding comfort to the passengers when the vehicle passes through a curved area and for the jolting is improved.
