Abstract
An anti-rolling control system for an automotive vehicle is provided. This control system comprises shock absorbers each disposed between a vehicle body and a suspension member rotatably supporting a wheel and being variable of damping force within a range from soft to hard damping characteristics, a steering sensor for monitoring a steered angle of a steering wheel, and a rolling motion control unit. The rolling motion control unit is operable to derive steering angular velocity based on the steered angle of the steering wheel to determine a transient status of vehicle rolling motion when the steering angular velocity is greater than a threshold value. When the vehicle is in the transient status of rolling motion, the damping forces of the shock absorbers are modified to suppress the rolling motion.
