A steer-by-wire system includes a transmission torque sensor, a handwheel position sensor, and a controller. The transmission torque sensor is configured to measure and output a transmission torque signal. The handwheel position sensor is configured to measure and output a handwheel position signal. The controller includes an angle-based load calculation submodule, a torque steer ratio calculation submodule, and a torque control module. The angle-based load calculation submodule is configured to transform the transmission torque signal and the handwheel position signal into an estimated second load value. The torque steer ratio calculation submodule is configured to transform the estimated second load value, a first load value indicative of roadwheel load including torque steer influence, and the transmission torque signal into a torque steer ratio. The torque control module is configured to transform the first load value, the handwheel position signal, and the torque steer ratio into a handwheel torque command signal.
