Abstract
An automotive suspension system has a roll stablizer with an adjustable torsion modulus. The torsion modulus of the stabilizer is adjusted depending upon road surface conditions and other parameters. A controller is associated with the stabilizer to adjust its torsion modulus. When the vehicle is moving on a relatively smooth road surface, the torsion modulus of the stabilizer is adjusted toward to a relatively high value. On the other hand, when the vehicle travels along a rough road, the torsion modulus is adjusted toward a lower value.
