Abstract
A roll control apparatus for a vehicle which comprises front wheel side and rear wheel side active stabilizer devices and a control unit that is configured to control the stabilizer devices, to calculate a target anti-roll moment, to determine optimum control gains of electric actuators of the stabilizer devices among pre-stored control gains based on a vehicle speed and a frequency of change in a roll angle of a vehicle body, and to control the electric actuators so that a sum of anti-roll moments generated by the front wheel side and rear wheel side active stabilizer devices becomes the target anti-roll moment and control gains of the electric actuators become the optimum control gains.
