Claim 7:
8. A method for active roll control, comprising:
within with a computerized processor within a vehicle,
monitoring a driving mode including one of straight-line driving and rounding a curve on a road;
monitoring an output of a sensor operable to monitor a tilt of a vehicle body of the vehicle;
determining a desired roll moment based upon the driving mode and the output of the sensor; and
controlling an active roll control motor of an active sway bar of a vehicle suspension system based upon the desired roll moment;

wherein the active sway bar is operable to transmit a force from a first side of the vehicle suspension system to a second side of the vehicle suspension system in order to provide control over the tilt of the vehicle body, and
wherein, when the driving mode includes the straight-line driving, controlling the active roll control motor includes turning a first bar portion of the active sway bar in relation to a second bar portion of the active sway bar to control body roll accelerations that result from side-to-side road surface irregularities.
