Claim 17:
18. A vehicle apparatus, comprising an electronic power steering (EPS) unit comprising one or more processors and non-transient computer-readable media encoded with programming instructions, for control of the EPS unit is configured to:
send a torque control that is based on input control signals from a vehicle trajectory control system that causes a corrective action by a feed-forward control of a steering controller of a steering system;
identify at least one parameter of at least one lateral control feature that causes at least a result in an optimized value in an outcome of a control for at least one lateral control feature and enables a robust response to an uncertainty of at least one uncertain value in the control;
calibrate an output control signal generated by a vehicle trajectory controller coupled to the steering controller, by quantifying the uncertainty of at least one uncertain value in the at least one lateral control feature wherein uncertainty of the at least one uncertain value in the at least one lateral control feature is caused from at least one component variant in a configuration of components associated with a vehicle variant; and
send a torque control command to compensate for the uncertainty of the at least one uncertain value in the configuration of components associated with the vehicle variant by adjusting at least one parameter of the at least one lateral control feature wherein the adjusting of the at least one parameter causes a suboptimal value of the outcome of the control for the at least one lateral control feature.
