Abstract
A method to control a vehicle includes monitoring desired vehicle force and moment, monitoring real-time corner constraints upon vehicle dynamics which includes monitoring corner states of health for the vehicle, and monitoring corner capacities for the vehicle. The method further includes determining a desired corner force and moment distribution based upon the desired vehicle force and moment and the real-time corner constraints, and controlling the vehicle based upon the desired corner force and moment distribution.
