An actively controlled suspension system for automotive vehicles includes a lateral acceleration sensor and a controller for suppressing rolling of the vehicle. The controller controls a distribution ratio of anti-roll moment or lateral load shift between a driven wheel and a non-driven wheel so as to enhance steering characteristics of the vehicle. The controller changes the distribution ratio depending on both the lateral acceleration and the wheel speed difference between the driven wheel speed and the non-driven wheel speed such that the distribution ratio at a non-driven wheel side of suspension system is increased from a designated reference value according to the increase in the wheel speed difference and a rate of change in the distribution ratio is attenuated towards the designated reference value according to the increase in the lateral acceleration. |

DETAILED DESCRIPTION It is, in view of the above disadvantages, a principal object of the present invention to provide an actively controlled suspension system for automotive vehicles which can provide a high reliability of an anti-rolling control during turns, irrespective of a road surface condition, such as icy or wet roads and dry pavement, a lateral acceleration exerted on the vehicle body, and the wheel speed difference between driven and non-driven wheels.
It is another object of the invention to provide an anti-roll controlling system for automotive vehicles which can provide a high cornering stability of the vehicle, irrespective of a road surface condition.
It is a further object of the invention to provide an anti-roll controlling system for automotive vehicles which can insure both reasonable anti-roll effect and superior steering characteristics during turns, irrespective of a road surface condition.
It is a still further object of the invention to provide an anti-roll controlling system for automotive vehicles which can provide an optimal lateral load shift distribution between front and rear suspension systems, irrespective of the degree of turn of the vehicle, such as hard turn or moderate turn, and the magnitude of slippage of driven wheel.
In order to accomplish the aforementioned and other objects, an actively controlled suspension system for an automotive vehicle is provided, which includes: a sensor for monitoring a lateral acceleration exerted on a vehicle body, to generate a lateral acceleration indicative signal; a control element for controlling a lateral load shift between left and right wheels depending on the lateral acceleration indicative signal so as to suppress rolling of the vehicle body; an element for controlling a distribution ratio of said lateral load shift, between a driven wheel side of suspension system and a non-driven wheel side of suspension system, so as to enhance steering characteristics of the vehicle; a speed sensor for monitoring a driven wheel speed to generate a driven wheel speed indicative signal; and another sensor for monitoring a non-driven wheel speed to generate a non-driven wheel speed indicative signal
