In this system for vehicle roll control, one actuator assembly is provided corresponding to each vehicle wheel and resiliently suspends it from the vehicle body. Each of these actuator assemblies is adapted to increase or decrease the vehicle height at its vehicle wheel as a result of a control signal being supplied. Control means are provided corresponding to the actuator assemblies and serve to supply control signals to them. A vehicle speed detecting means senses road speed, a steering angle detecting means senses steering angle, a means senses the rate of change of steering angle, and a means detects the actual roll angle phi t of the vehicle body. A computing and control means computes a steady state roll angle phi INFINITY of the vehicle body from the vehicle speed and the steering angle, advances the phase of a signal representative of the steady state roll angle phi INFINITY to thereby compute a compensating value PHI INFINITY of roll angle, computes an amendment value phi x of roll angle in accordance with the rate of change of steering angle, computes the difference phi based upon the desired roll angle phi a of the vehicle body, the compensating value PHI INFINITY , the amendment value phi x, and the actual roll angle phi t following the equation: phi = phi a- (k1 PHI INFINITY +k2 PHI t+k3 PHI x), where k1, k2 and k3 are positive constants; and controls the actuator assemblies, via the control means, in accordance with the difference phi , when the absolute value of the difference phi is larger than a predetermined value.
