Abstract: The invention provides a method and computer usable medium, including a program, for vehicle stability control. A rear axle cornering stiffness coefficient in a linear handling range is determined. A first understeer coefficient in a linear handling range is determined. A desired lateral acceleration is determined based on the first understeer coefficient. A second understeer coefficient is determined based on a limited magnitude of the desired lateral acceleration. A desired yaw rate is determined based on the second understeer coefficient. A desired lateral velocity is determined based on the desired yaw rate and the rear axle cornering stiffness coefficient.

Abstract: In an unified control of a plurality of active chassis systems a role of each chassis system in applying a corrective net force and a corrective moment to a vehicle is determined. In determining the roles, control influence coefficients and a control authority of each active chassis system is determined. An activation status of each active chassis system based on the control influence coefficients and the control authority is subsequently determined.
