PURPOSE:To control attitude in a normally optimum state irrespective of steady turn and rapid turn, by a method wherein a two kinds of large and small flow passages are situated in a device, feeding and discharging fluid to and from each fluid spring chamber, two kinds of the flow passages are switched according to the steering state of a vehicle. CONSTITUTION:A controller 24 detects rolling, occurring to a car body, based on signals from a steering sensor 30 and a car speed sensor 32. Intake valves 19a-19b and exhaust valves 20a-20d are connected and disconnected to main air spring chambers 11a-11d in front right, front left, rear right, and rear left suspension units SFR, SFL, SRR, and SRL. In this case, switching valves 18a and 18b, having two kinds of large and small flow passages, are situated in front and rear suction pipings A1 and A2 respectively communicated to a reserve tank 17. The switching valves 18a and 18d are controlled for switching by means of a controller 24 according to a detecting signal from the steering sensor 30. |
