Abstract
Herein, a particular vehicle suspension control arm in a suspension having multiple control arms is designed to create a range of available axial stiffness levels which relates to a range of toe change at the wheel under to lateral loading. In particular, a semi-active device is arranged on a given suspension control arm to allow a change in stiffness that produces a desirable amount of toe change under the presence of lateral loading. This suspension arrangement, when applied to the rear axle of an automobile, has significant merit in being able to enhance maneuverability and stability over a large range of operating conditions at a minimal level of control input energy and with robust failsafe operation.
