  • Patent number: 11491970
    Abstract: A method of controlling stability of a vehicle and a stability control system for the vehicle. A driver command is determined based on driver input data. At least one output command is sent to one or more vehicle systems to control stability of the vehicle based on the driver command. A controller sends the output command based on a control hierarchy that provides an order in which the controller controls body motion of the vehicle, wheel slip of the vehicle, and standard stability of the vehicle to control stability of the vehicle. The order dictates that the controller controls the body motion of the vehicle and the wheel slip of the vehicle before the controller controls the standard stability of the vehicle. A state of one or more of the vehicle systems is controlled based on the sent output command as dictated via the control hierarchy.
