Abstract

An adjusting automobile suspension system providing a controlled camber response to the attitude of a vehicle, the forces acting on such vehicle and/or the type of road surface for example when the vehicle is navigating a turn and/or accelerating or braking. The system includes sensors that monitor the magnitude of centrifugal and vertical forces on the vehicle, the direction and degree that the steering wheel is being turned, the magnitude of longitudinal forces acting on the vehicle, the individual rotational wheel speed at each wheel of the vehicle and camber of each wheel with respect to the vehicle body. In response to the sensed change in the vehicle's attitude, the sensed forces acting upon such vehicle, and/or the type of road surface monitored by a central control processor, a series of servo mechanisms are activated to alter the camber of each wheel to optimize tire contact with the road surface, as well as to adjust other suspension parameters (toe-in/toe-out caster, wheel height, wheel track) of each wheel due to mechanical misconfigurations that become inherent in certain suspension designs when servo-mechanisms alter the camber of each wheel.
