Abstract
A method of controlling a vehicle includes determining a desired sideslip angle in the moving road plane, determining an actual sideslip angle in the moving road plane, a desired yaw rate in the moving road plane, and an actual yaw rate in the moving road plane. A controller controls the vehicle system in response to the desired slip angle, the actual sideslip angle, the desired yaw rate and the actual yaw rate in the moving road plane.
