<p>A control system for a power machine (10) having independently steerable and rotatable wheels (124) includes a user input device and an electronic controller (116). The user input device includes user actuable inputs (114) providing user actuation signals. The electronic controller (116) is configured to receive a plurality of user selectable operating parameters. Based on user actuation of the user actuable inputs (114), the electronic controller (116) provides a steering control signal to control steering of the wheels (124), and a speed control signal to control speed of the wheels (124) based on the operating parameters received, and provides a differential speed control signal to the wheels (124). The control system can also include a wheel speed sensor (118), a steering angle sensor (119), and at least one controllable differential (129), all coupled to the controller (116). The steering angle sensor (119) provides a steer angle signal of an associated wheel (124. The controllable differential (129) allows each wheel to rotate at a different rate from.</p> |
