PURPOSE:To perform the neutral setting of a steering sensor so accurately, by clearing output of the steering sensor in accordance with a car speed and acceleration in both directions, in case of a device which controls the extent of roll displacement in a car body at the time of turning on the basis of the output of the steering sensor counting an operation angle value. CONSTITUTION:A device bearing the above caption is provided with suspension units FS1, FS2, RS1 and RS2 (hereinafter referred to as S) at each wheel. Each unit S performs level control operation in a way of controlling the feed and discharge of air to a main air spring chamber 7 by a control unit 37. In addition, it controls the extent of roll displacement in a car body at the time of turning on the basis of an operation angle value out of a steering sensor 41 which counts the operation angle value each time a steering wheel 42 rotates at the specified angle rotation. In this case, when the car speed detected by a car speed sensor 38 is less than the setting car speed and acceleration in both directions detected by an acceleration sensor 39 is within the setting acceleration, the operation angle value out of the steering angle sensor 41 is cleared. With this constitution, neutrality in the steering angle sensor 41 is set accurately, whereby roll control is made so as to be accurately performed. |
