A method for determining a steering wheel overlay torque for transmission to a steering wheel of a steer-by-wire steering system is disclosed. An example steer-by-wire steering system includes a steering wheel actuator operatively coupled to a steering wheel, a road wheel actuator operatively coupled to steerable wheels of the vehicle, and programmable circuitry to communicate with the steering and road wheel actuators, the programmable circuitry to at least one of instantiate or execute machine readable instructions to identify an overlay force to be applied by the road wheel actuator, the overlay force from a driver assistance function, identify a torque encountered by the steering wheel, determine a steering wheel torque that corresponds with the overlay force and the torque encountered by the steering wheel, and determine an overlay torque for the steering wheel actuator based on the steering wheel torque and the torque encountered by the steering wheel.
