A system for moving material from a first work area to a second work area includes a change in terrain sensor, a machine position sensor, and a controller. The controller performs first material moving operations including tip head operations until the void at the second work area is filled to a predetermined extent. The controller performs second material moving operation including backstacking operations until a predetermined amount of material has been moved from the first work area.

A system controls a work machine including a work implement. The system includes a load sensor and a processor. The load sensor detects a load acting on the work implement. The processor controls the work machine to dig a digging wall formed between adjacent slots. The processor moves the work machine to either one of the adjacent slots adjacent to the digging wall when the load during digging the digging wall is equal to or greater than a first threshold. A method is executed by a processor to control the work machine. The method includes detecting a load acting on the work implement, controlling the work machine to dig the digging wall, and moving the work machine to one of the adjacent slots when the load during digging the digging wall is equal to or greater than a first threshold.

The present disclosure relates to a grader and a blade control method. The grader includes: a blade mechanism including a blade; a blade adjusting mechanism including a plurality of adjusting means respectively corresponding to at least two degrees of freedom of the blade, and configured to adjust a spatial position and/or angle of the blade; a blade position detecting mechanism configured to detect a slope parameter for characterizing a spatial position of the blade; a motion trajectory library configured to store motion functions of the plurality of adjusting means respectively when different operation conditions and/or different grades are switched; a controller configured to call a corresponding motion function in the motion trajectory library according to a set operation condition and a required slope, and control at least one of the plurality of adjusting means according to a position parameter of the blade and the motion function.

A ramping subsystem of a control system for a dual path electronically controlled hydrostatic transmission is used to modify the commanded rate of change of pump and motor acceleration, deceleration and direction change command (performed to command machine motion from forward to reverse or vice versa) in order to achieve desired machine performance and operator feel. Pump and motor acceleration, deceleration and direction change command rates are then further modified using scaling tables based on selected maximum machine speed using operator input device.

A system for determining an optimized cut location for a work implement includes a position sensor and a controller. The controller is configured to determine the position of a work surface and perform a coarse analysis along a path based upon the position of the work surface and a coarse analysis parameter threshold to select a selected coarse analysis increment. The controller is further configured to perform a fine analysis along the selected coarse analysis increment based upon the position of the work surface and a fine analysis parameter threshold to select the optimized cut location.

A control system is disclosed. The control system may include a first input component to control a lean angle of at least one set of wheels of a machine and to provide a visual and/or tactile indication of the lean angle. The control system may include a second input component to control an articulation angle of an articulated joint of the machine and to provide a visual and/or tactile indication of the articulation angle. The control system may include a third input component to control a rotation angle of an implement of the machine and to provide a visual and/or tactile indication of the rotation angle.

Power based self-sensing of a rotor position of an SR motor at mid to high speeds and low torque is achieved by an SR motor control system by comparing the motor power to an injection maximum power. A position current pulse is injected to a stator pole in response to the motor power being less than the injection maximum power. An actual stator current created by the position current pulse is compared to an estimated stator current, and a stored estimated rotor position in a memory is updated to a new estimated rotor position if the actual stator current is not equal to the estimated stator current.

A first process acquires movement data including a position of a lead machine. A second process controls one or more work machines so that the one or more work machines follows the lead machine based on the movement data.

A system includes a processor and a display. A work machine includes a vehicle body and a work implement attached to the vehicle body. A camera captures a surroundings image in a traveling direction of the work machine. The processor acquires image data indicative of the surroundings image. The processor synthesizes a guide display and the surroundings image and generates an image including the surroundings image and the guide display. The display displays the image including the surroundings image and the guide display based on a signal from the processor. The system may further include the work machine and the camera.

A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move a work implement of the work vehicle along the design surface. The controller determines if slip of the work vehicle has occurred. Upon determining that slip has occurred, the controller changes the design surface to a position equal to or higher than a blade tip position of the work implement when the slip occurred.
