Abstract: A suspension device includes a wheel supporting member configured to rotatably support a wheel. Two links respectively link the wheel supporting member and a vehicle-body side member and are disposed substantially in parallel in a vehicle width direction. At least one projecting portion extends from at least one of the two links towards the other link, and an elastic linking portion links the projecting portion of one of the links to at least one of the other link and the projecting portion of the other link. A toe angle adjusting device is configured to input a force in a direction oriented backward in the vehicle forward-backward direction to the wheel supporting member to adjust a toe-in angle of the wheel.

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.

Abstract: A rear wheel toe angle control device that ensures a stable steering performance even when the cornering powers of laterally opposing rear wheels are different from each other. When a reduction in the cornering power of one of the rear wheels owing to a drop in the tire pressure or a temporary tire is determined, a control unit changes the toe angle of the other rear wheel in a direction to increase the slip angle of thereof, and additionally changes the toe angle of the one rear wheel in a direction to decrease the slip angle of thereof. The combined cornering power of the two rear wheels is maintained at a normal level, and the steering performance of the turning vehicle remains the same. This also contributes to a stable running performance of the vehicle, and a maximization of the total available cornering power of the rear wheels.
