The integration of brakes and steering actuators in vehicle lateral dynamics control is of primary relevance due to the high control authority these actuators insure. Moreover this is a challenging control problem as it is MIMO, intrinsically non-linear due to tyres characteristic and with high plant uncertainty due to variations of major parameters. This paper presents the application of state feedback linearization technique to the problem and shows some vehicle test results. The controller results globally stable, smooth and effective with the steering actuator and uses the braking correction only in critical cases.
