Abstract
A full vehicle suspension control derives the vertical wheel and vertical body corner velocities at each corner of the vehicle body and derives therefrom a set of at least three body state velocity variables descriptive of vertical body motions and attitude. These body state velocity variables may be the body heave, roll and pitch velocities or a plurality of the vertical body corner velocities. The suspension control computes desired forces between each body corner and its corresponding wheel from a linear combination of the vertical wheel velocity of that wheel and the body state velocity variables and derives control signals from the desired forces and, in a semi-active system, the sign of demand power. The control signals are applied to vertical force actuators connected to exert vertical forces between the vehicle body and wheel at the vehicle body corners and capable of response at frequencies sufficient to control wheel as well as body vibrations in real time.
