Abstract: A mounting system for mounting a sensor assembly to a pair of rotatable members coupled by an articulation joint includes a sensor mounting plate. The sensor mounting plate is coupled to a first rotatable member and supports at least one sensor element thereon such that the at least one sensor element is in alignment with an axis of the articulation joint. The mounting system also includes a target mounting plate that is disposed in a spaced-apart manner from the sensor mounting plate. The target mounting plate has a target mounting portion for supporting the target element thereon, and a support arm extending from the target mounting portion. Further, the mounting system also includes a post having a first end configured to couple with the second rotatable member and a second end that is configured to adjustably support the support arm of the target mounting plate via an adjustment block.

Abstract: A system may comprise a plurality of sensors configured to transmit sensor information regarding a speed of a machine, a position of an implement of the machine, a payload of the machine, a grade of a surface on which the machine is traveling. The system may further comprise an electronic control module configured to receive steering command information regarding a steering command of the machine; determine, based on the steering command information, one or more articulation parameters associated with the steering command, determine the speed, the position of the implement, the payload, and the grade based on the sensor information. The electronic control module may be configured to determine one or more articulation parameters thresholds based on the speed, the position of the implement, and the payload of the machine; and modify the steering command when the one or more articulation parameters exceeds the one or more articulation parameters thresholds.

Abstract: A method for steering alignment calibration of an articulated machine having front and rear frames pivotally connected by an articulation joint to steer the machine may include displaying a steering alignment calibration screen with a target steering angle between the frames and a calculated steering angle. The calculated steering angle may be determined based on a sensed steering angle and a calibration steering angle. The machine is steered until the displayed calculated steering angle is equal to the target steering angle. If an actual steering angle of the machine is not equal to the target steering angle, further steering is performed until the actual steering angle is equal to the target steering angle. The calibration steering angle may be recalculated and stored for future use when the actual steering angle is equal to the target steering angle but the calculated steering angle is not equal to the target steering angle.

Abstract: A work machine may include a steering system, a user interface, a detection device, and a control device. The user interface may generate an input signal corresponding to operator input. The detection device may generate a detection signal corresponding to a presence of an operator relative to the user interface. The control device may determine that the operator is unavailable based on the detection signal and the input signal, and enable a lockout mode based on determining that the operator is unavailable. The control device may determine, while the lockout mode is enabled, a readiness indicator. The readiness indicator may confirm a readiness of the operator based on determining that the detection signal satisfies a readiness criterion. The control device may disable the lockout mode based on determining that the readiness criterion is satisfied.

Abstract: A system and method for mitigating collisions for an articulated work vehicle is disclosed. The system includes a controller configured to determine a safe-zone around the articulated work vehicle based on signals corresponding to sensed objects around the articulated work vehicle. The controller is further configured to determine a position and velocity of one or more peripheral points on the articulated work vehicle based on signals from a set of sensor systems operatively coupled to the articulated work vehicle. The controller is further configured to receive a driver control input. The controller is further configured to apply a limit to the driver control input when a peripheral point on the articulated work vehicle is expected to be within a predetermined distance to a nearest edge of the safe-zone.

Abstract: A payload optimization system is disclosed and may include one or more visual sensors operably coupled to a hauling machine and configured to scan and produce a payload body data set. The system may further include a loading machine including a payload bucket configured to load a payload into the payload body. Moreover, a loading system controller may be communicably coupled to each of the hauling machine and the loading machine and configured to identify the hauling machine and the loading machine using a set of machine identifiers. Moreover, the controller may receive the payload body data set from the one or more visual sensors, generate a payload body map, and program a loading sequence of the payload body based on the payload body map. The loading system controller may transmit and display the loading sequence configured to guide a loading cycle between the hauling machine and the loading machine.

Abstract: A system and method for limiting articulation between a front frame and a rear frame of an articulated machine are disclosed. The system and method receive steering signals and determine impending contact between the front frame and the rear frame based on the received steering signals. Additionally, an amount by which to reduce torque at a hitch coupled between the front and rear frames so as to limit an articulation characteristic of the front frame relative to the rear frame to a predetermined value is determined, responsive to determination of impending contact. Prior to contact, rimpull of the articulated machine is reduced based on the determined amount of torque.
