Abstract
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.
