This paper proposes a linear predictive lateral control method to stabilise highly automated vehicle (HAV) at the tire-road friction limits when tracking (tight) desired path. Two approaches are adopted linearise model around tire saturation region: (1) force of front is selected as input instead steer angle and (2) rear dynamics locally linearised current operating point within horizon. The both tires utilised define an enveloped stable zone, which serves safety constraints for controller....
