INTRODUCTION 1.1 Background The rollover of heavy vehicle is an important road safety prob-lem world-wide. First production car was Mitsubishi Mirage Cyborg in 1988. It connects opposite (left/right) wheels through short lever arms connected by a torsion spring. The center of the sprung mass shifts outboard of the vehicle centerline, which creates a destabilizing moment that degrades roll stability. The control signal is the current entering the electronic servo-valve and the output is the force generated by the hydraulic actuator. Genuine Land Rover; Range Rover L405; Range Rover Sport L494; Anti Roll Bar; Control Pump; LR035471; Additional Information. Activa active anti roll bars. Active Anti-Roll Bar. The active anti-roll bar system has been proven to be one of the most effective solutions to improve roll stability of heavy vehicles. When the anti-roll bars are uncoupled, the axle can achieve an additional torsional twist of max. An active anti-roll bar system has to balance the trade-off between ride comfort and handling performance. Semi active anti-roll bars. In a previous work, the authors proposed an integrated model, including four electronic servo-valve hydraulic actuators in a linear yaw-roll model on a single unit heavy vehicle.
