Abstract
A method of controlling a work machine having at least one wheel includes providing a controller, an operator control, and a steering system including a steering wheel position sensor, a road wheel angle sensor, a speed sensor, and a feedback device. The method includes detecting a change in steering wheel position via the steering wheel position device and a wheel speed of the at least one wheel via the speed sensor. A predicted lateral acceleration is calculated by the controller as a function of wheel speed and a feedback torque is determined by the controller as a function of the predicted lateral acceleration. The feedback torque is determined from a plurality of feedback torque curves stored by the controller, where each of the plurality of feedback torque curves corresponds to a sensitivity level selectable from the operator control. The feedback torque is commanded to the feedback device.
