Abstract: A system, method, and apparatus for controlling acceleration of a machine when the machine exits a grade. The system, method, and apparatus may determine a virtual gear having a maximum speed limit equivalent that matches the speed of the machine as the machine exits the grade. The system, method, and apparatus may also deactivate an automatic retarding control (ARC) strategy, which may be activated when the machine is on the grade to reduce and limit the speed of the machine to no more than a set speed, if the ARC strategy is active as the machine exits the grade. The system, method, and apparatus may also control automatic downshift of a transmission system to the virtual gear if the ARC mode was activing during the exit from the graded surface and is now deactive.

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 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 machine having a powertrain including an engine operably connected to a torque converter and a transmission. The machine includes a control system receive an activation signal indicative of an automatic mode operation of the machine and command the torque converter to remain in a direct-drive mode while the transmission shifts from a first gear ratio to a second gear ratio. The control system also limits engine speed below a first engine speed limit when a gear ratio setting of the transmission is indicative of the second gear ratio.

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.
