Controller

A system for automated control of a motor grader includes a first sensor to indicate bounce of the motor grader and a speed sensor to indicate the ground speed. A controller determines a maximum amplitude of the bounce of the motor grader and controls the ground speed of the motor grader at least in part based upon the maximum amplitude of the bounce. A method is also provided.

Anti-bounce control system for a machine

An articulated machine and method of operation, the articulated machine having a first frame with a first traction device and a steering apparatus that controls a steering angle thereof, the first frame pivotally coupled to a second frame at an articulation joint, the second frame having a second traction device, a steering sensor configured to provide a steering signal indicative of the steering angle, and an electronic controller configured to automatically control an articulation angle based on the steering signal.

Steering system with automated articulation control

A method of operating an articulated machine includes sensing an articulation angle and a wheel steering angle of the machine, and controlling a locking state of a differential responsive to a steering radius of the machine. An articulated frame wheeled machine is further provided, and includes a front frame unit with a wheel steering apparatus, a back frame unit and an articulation apparatus coupled between the front and back frame units. First and second sensors are operable to sense a wheel steering angle and an articulation angle of the machine, and an electronic control is provided which is configured to selectively lock or unlock a differential of the back frame unit responsive to a steering radius of the machine.
