CONTROL SYSTEM FOR WORK VEHICLE, METHOD, AND WORK VEHICLE

A control system for a work includes an operating device and a controller. The operating device outputs an operation signal indicative of an operation by an operator. The controller is in communication with the operating device. The controller determines a target profile of a terrain to be worked on. The controller generates a command signal to operate the work implement according to the target profile. The controller receives the operation signal from the operating device. The controller determines an operation of the work implement based on the operation signal. The controller corrects the target profile according to the operation by the operator when the operation of the work implement by the operator is performed.

Control system for work vehicle, control method, and work vehicle

A work vehicle control system includes an actual topography acquisition device, a storage device, and a controller. The actual topography acquisition device acquires actual topography information, which indicates the actual topography of a work target. The storage device stores design topography information, which indicates a final design topography that is a target topography of the work target. The controller acquires the actual topography information from the actual topography acquisition device. The controller acquires the design topography information from the storage device. The controller generates a command signal to move the work implement to a position that is between the actual topography and the final design topography, and a predetermined distance above the actual topography.

EARTH SHAPING VEHICLE RETROFITTED WITH REAR GRADING TOOL

An earth shaping vehicle (ESV) includes a chassis and a rear earth shaping tool. The chassis drives the ESV through the site from a first location in the site to a second location in the site. The front earth shaping tool moves earth from the first location to the second location. The rear earth shaping tool grades a ground surface between first location and the second location. Sensors coupled to the rear excavation tool produce one or more signals representative of a position and an orientation of the rear tool relative to the ground surface of the site. A controller produces actuating signals to actuate the rear excavation tool to grade the ground surface based on the one or more signals representative of the position and the orientation of the rear tool.

Ingress/egress arrangement for machine

An ingress/egress arrangement for a machine comprises an operator cabin and a walkway system outside the operator cabin. The operator cabin can include a plurality of posts, including first post and a second post, and a door rotatably coupled to the first post so as to be movable between at a fully open position and at a fully closed position. An opening in the operator cabin between the first post and the second post defines a first operator ingress/egress point. The walkway system provides operator access to inside the operator cabin via the door and the opening, and provides operator access to outside the operator cabin. The door, in the fully open position, can restrict operator access toward a front of the machine and can allow operator access simultaneously to the walkway system and a second operator ingress/egress point.

Implement travel prediction for a work machine

A controller may identify a command to move an implement in a particular direction and an amount of time for the implement to move in the particular direction. The controller may determine an estimated velocity of the implement moving in the particular direction. The controller may determine a predicted travel distance of the implement in the particular direction. The controller may cause, based on a stop position associated with the particular direction and the predicted travel distance of the implement in the particular direction, the implement to move from a current position to a reset position. The controller may cause the command to be executed to cause the implement to move, in the particular direction and for the amount of time, from the reset position to another position without hitting the stop position associated with the particular direction.

System for controlling operation of a machine
10858801 · 2020-12-08 · ·

A system for controlling operation of a machine having a frame supported by ground engaging members and a work implement movably supported by the frame includes a machine position sensor and an implement position sensor to output data pertaining to a position and orientation of the machine and the work implement within a worksite. The system further includes a controller that receives the data output by the machine position sensor and the implement position sensor. The controller computes an amount of gap that is required for alignment of the machine and the work implement with a slot based on the received data. The controller then controls a movement of the ground engaging members for positioning the machine at the computed amount of gap from a cut point located within the slot prior to the work implement entering a cut position for performing a cut within the slot.

The guard rail system includes at least one retention device provided in association with the bracket portion. The at least one retention device is adapted to removably affix the bracket portion to the portion of the track. The guard rail system also includes at least one receiving unit located on the bracket portion. The guard rail system further includes a rail member adapted to be removably affixed to the at least one receiving unit.

MATERIAL MOVING MACHINES AND PILOT HYDRAULIC SWITCHING SYSTEMS FOR USE THEREIN

In accordance with one embodiment of the present disclosure, a material moving machine comprises a pilot hydraulic switching system. The pilot hydraulic switching system comprises a control unit, a first directional valve, and a second directional valve. The control unit is configured to operate the first and second directional valves to shift a variable position actuator valve between a static state, a retract state, and an extend state. The actuator valve comprises a first and second control element.
