A system for reducing vehicle body roll by the active control was 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. The vehicle test data shows a great reduction of roll angle during turning. Also improvement of ride comfort is achieved by making the actuator freely rotatable, i.e., by connecting all chambers of actuator in normal driving conditions. Control algorithm with estimated lateral acceleration was applied to vary the pressure of actuator. ECU (Electronic Control Unit) with microcontroller was developed for implementation of this algorithm, and computer simulations were performed in order to get the knowledge of system characteristics and design parameters.
