PURPOSE: To enhance the comfort in sitting in a car cabin, secure rolling stiffness, and provide controllability for it in accordance with the running condition by equipping a car with a stabilizer device of fluid pressure type, and therein controlling the internal pressure of the stabilizer according to the car running condition.
CONSTITUTION: A controller 36 reads sensing signals G from a crosswise acceleration sensor 38 and judges whether or not the reading value G is greater than the reference value G0. In the case of 'No', it is considered to be in a cornering state with a small crosswise acceleration, and piston 30b of a control cylinder 30 is put in the neutral position. In the case of 'Yes', the piston 30b is moved in the direction of boosting the working pressure in compression side cylinder chambers U, L. This constitution prevents worsening of the comfort in car cabin even while running with bounces. Also the car steering characteristics under cornering can be controlled optimally.
