Abstract:
1. A method of controlling roll stiffness and roll moment distribution of a suspension system of a vehicle, the suspension system including: front and rear vehicle support means for supporting the vehicle and any given load carried by the vehicle, the given load having its centre of mass at a load position, and at least one roll moment reaction means providing a variable roll stiffness for the vehicle suspension system, the at least one roll moment reaction means including at least one cylinder and two opposing fluid chambers; the method including: controlling pressures in the two opposing fluid chambers to set roll moment distribution of the suspension system and set roll stiffness of the at least one roll moment reaction means in dependence on the given load carried by at least the rear or front of the vehicle such that once set, the roll moment and variable roll stiffness is fixed for the given load and load position.
