Steering control system
A steering control system for a vehicle that considers the limitations of at least one of the vehicle and the environment is contemplated. The steering control system can receive a vehicle characteristic, an environmental condition, a desired amount of turning, and a desired velocity of the vehicle. Based on some, or all of these parameters, the steering control system can determine at least one of a wheel torque, a wheel angle, a wheel camber, and a wheel suspension for a desired vehicle path to enhance vehicle performance.

10. The steering control system of claim 5 , wherein the vehicle comprises a second motive element, and wherein the calculating controller is configured to independently determine (i) the correcting torque and the correcting angle for the first motive element, and (ii) a second correcting torque and a second correcting angle for the second motive element.
11. The steering control system of claim 10 , wherein the effecting controller is configured to independently adjust (i) the first motive element to apply the correcting torque and the correcting angle, and (ii) the second motive element to apply the second correcting torque and the second correcting angle.
12. The steering control system of claim 5 , wherein the first motive element is selected from the group consisting of a wheel or a track.
