An amount of information of data of a captured image displayed on a display unit is increased. A display control unit sets a plurality of divided display sections for a display unit. The display control unit sets a first camera group and a second camera group including one or more of a plurality of cameras. The first camera group captures an image of a work performed with a blade. The second camera group captures an image of a work performed with a ripper. The display control unit displays data of captured images output from cameras included in one of the first and second camera groups in a corresponding plurality of divided display sections.

A hybrid bucket assembly for a work vehicle having movable loader arms includes a reinforcing structure having a first edge plate, a second edge plate and at least two support members extending from the first edge plate. The reinforcing structure is for coupling the bucket assembly to the movable loader arms. The bucket assembly includes a double-wall bucket defining a volume for carrying material. The bucket is coupled to the at least two support members of the reinforcing structure, and the bucket has a leading edge coupled between the first edge plate and the second edge plate.

A construction machine comprising a chassis, a steering, and a powertrain for driving the construction machine by the chassis, an earth-moving tool for working a terrain, and a measuring system having a first measuring unit configured for generating first measuring data in a first detection range and comprising at least a first camera and a first LiDAR scanner configured for rotating a first measuring beam around a first axis and around a second axis non-parallel to the first axis with a rotating speed of at least 0.5 Hz with respect to each axis, an interface connecting the first measuring unit to a computer configured for, based on the first measuring data, at least one of generating a three-dimensional model of the terrain within the first detection range, identifying an obstacle or a person within the first detection range, and controlling the steering, the powertrain, and/or the earth-moving tool.

A system and method for steering a machine. The system may comprise a controller configured to receive a steering command and determine a target angular turn rate for the body and a target turn direction for the body. The controller may be further configured to determine a steering mode based on a transmission output torque, the steering mode including Traction-steering, Assisted-steering or Implement-steering. When the steering mode is Assisted-steering, the controller is configured to steer the machine in the target turn direction and at the target angular turn rate by (a) moving an implement from a first position to a second position and (b) diverting or removing power from a first ground engaging traction member. When the steering mode is Implement-steering, the controller is configured to move the implement from a first position to a second position to steer the machine in the target turn direction and at the target angular turn rate without diverting or removing power from the first ground engaging traction member.

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.

A system and method are provided for determining the position and orientation of an implement on a work machine in a non-contact manner using machine vision. A 3D camera, which is mounted on the vehicle with a field of view that includes components on the implement (e.g., markers in some examples), determines a three-dimensional position in a local coordinate system of each of the components. A global positioning system in cooperation with an inertial measurement unit determines a three-dimensional position and orientation of the 3D camera in a global coordinate system. A computing system calculates a three-dimensional position in the global coordinate system for the components using the local three-dimensional positions of the components and the global three-dimensional position and orientation of the 3D camera. The position and orientation of the implement can then be calculated based on the calculated global three-dimensional positions of the components.
