Abstract
A motor vehicle has a body supported on a front pair of wheels and a rear pair of wheels with front suspension apparatus providing controllable vertical wheel constraint and roll stiffness and a rear pair of wheels with rear suspension apparatus providing controllable vertical wheel constraint and rear roll stiffness. Responsive to a commanded vehicle acceleration or braking, the driven wheel (acceleration) or front (braking) suspension apparatus is briefly altered to provide optimal tire patch traction for the one of the pair of wheels. The alteration may be further responsive to vehicle speed and/or lateral acceleration. The controllable part of the suspension apparatus may be dampers, springs or anti-sway apparatus such as torsion bars. If anti-sway apparatus, the front and/or rear roll stiffness may be controlled to promote oversteer at low vehicle speed and understeer at high vehicle speed.
