Abstract
A vehicle includes a system that performs a method of operating the vehicle. A steering rack is coupled to at least one of a left wheel and a right wheel. A sensor obtains a measurement of a dynamic parameter of the vehicle related to a force at the steering rack. A processor determines a first estimate of a rack force resulting from the force based on the measurement of the dynamic parameter, obtains a second estimate of the rack force based on a signal from a road wheel actuator coupled to the steering rack, selects an arbitrated rack force from the first estimate of the rack force and the second estimate of the rack force, and activates a hand wheel actuator coupled to a steering wheel of the vehicle based on the arbitrated rack force to generate a feedback torque at the steering wheel.
