Abstract
A method to control a vehicle having a plurality of wheels includes monitoring desired vehicle dynamics, determining a desired corner force and moment distribution based upon the desired vehicle dynamics and a real-time closed form dynamics optimization solution, and controlling the vehicle based upon the desired corner force and moment distribution. The real-time closed form dynamics optimization solution is based upon a minimized center of gravity force error component, a minimized control energy component, and a maximized tire force reserve component.
