ARC (Active Roll Control) system operates the actuators either in the middle of the stabilizer bar (Rotary type) or at one end of stabilizer bar (Linear type) in order to reduce the roll angle. Here we apply ARC technology to a sedan and simulate it, in which the stabilizer bar stiffness changes along with the actuator stroke related to the lateral acceleration. Besides the roll angle reduction, it can improve the yaw rate behavior, too. The control logic of the linear ARC consists of three modules, 'Active Roll Compensation', 'Active Roll Damping' and 'Moment Distribution'.
