Abstract: A vehicle, system and method of operating a vehicle. A sensor for measures a dynamic variable of the vehicle. A processor determines a location of a perceived yaw center (PYC) of the vehicle from the dynamic variable, tracks a desired location of the PYC, and adjusts a control parameter of the vehicle to reduce a difference between the location of the PYC and the desired location of the PYC.

Abstract: A vehicle, system and method of operating the vehicle. A sensor measures a dynamic parameter of the vehicle. A processor determines a lateral force on a first tire based on the dynamic parameter of the vehicle, determines a longitudinal force on the first tire that achieves a maximal grip of the first tire for the lateral force, and adjusts a first torque on the first tire in order to achieve the determined longitudinal force at the first tire.

Abstract: Methods of controlling axle torque distribution of a vehicle during steering through a curve include collecting, via a controller: input data which is representative of a plurality of vehicle inputs; vehicle data which is representative of axle torque of the front axle and axle torque of the rear axle; and constraint data which is representative of real-time constraints of the vehicle. The collected input data, vehicle data and constraint data are communicated to a predictive model. Determining, using the predictive model, whether torque adjustments are necessary. The distribution of the axle torque of the front axle and the axle torque of the rear axle is controlled, via the controller, when the torque adjustments are necessary as determined via the predictive model.

Abstract: A method and system of controlling a vehicle includes providing a plurality of dynamic state inputs to a controller in the vehicle that is adapted to execute a plurality of control loops and further includes determining an operating mode of the vehicle. Based on the operating mode of the vehicle, a location of an optimum perceived yaw center of the vehicle is determined corresponding to a selected estimation technique using the dynamic state inputs and wherein the estimation technique is selected based upon the determined operating mode of the vehicle. The information related to the location of the optimum perceived yaw center may be used as input for controlling the vehicle in a dynamic state.

Abstract: A vehicle, system and a method of driving a performance vehicle. The system includes a sensor for detecting a value of driver input to the vehicle, and a processor. The processor is configured to compare the value of the driver input to a threshold value for the driver input, switch to a performance mode operation for the vehicle when the value of the driver input is greater than the threshold value, generate a command at the vehicle based on the value of the driver input using a performance model of the vehicle activated in the performance mode, and activate a performance actuator of the vehicle to generate a dynamic parameter at the vehicle from the command.
