A System for reducing vehicle body roll by active control is developed. The stabilizer bar with hydraulic rotary actuator produces anti~roll moment which suppresses roll tendency. This reduction of roll improves the driving safety as well as the ride comfort. Vehicle test data shows considerable reduction of roll angle during steady-state turning. Also improvement of ride comfort is achieved by making the actuator freely rotatable, i.e. by connecting all chambers of actuator in normal driv-ing conditions. A control algorithm using steering wheel angle and vehicle speed signal as input value is applied. It is compared with signal of the G-sensor
