CONSTRUCTION MACHINE
A construction machine acquires efficiently and accurately the target surface to be displayed or controlled. The construction machine includes: a design surface information storage unit storing three-dimensional target shape as multiple design surfaces; a work equipment velocity vector acquisition unit detecting or estimating the velocity of work equipment; a work equipment position acquisition unit detecting or estimating the position of the work equipment; a target surface acquisition unit acquiring a principal target surface to acquire an estimated target surface that is potentially the next principal target surface; an operation control unit correcting the work equipment velocity; and a display unit displaying the positional relations between the work equipment position and the principal target surface. The target surface acquisition unit includes an estimated target surface calculation unit determining as an estimated target surface the design surface located in the direction of the work equipment velocity vector.
Systems and methods for controlling machine ground pressure and tipping
Methods and systems for operating an industrial machine. One system includes a controller that includes an electronic processor. The electronic processor is configured to calculate an eccentricity of a center of gravity of the industrial machine with respect to a center of a bearing propelling the industrial machine and calculate a ground pressure associated with the bearing based on the eccentricity of the center of gravity. The electronic processor is also configured to set a maximum torque applied by an actuator included in the industrial machine to a value less than an available maximum torque based on the eccentricity of the center of gravity and the ground pressure.

EXCAVATING IMPLEMENT HEADING CONTROL
An excavator comprises a chassis, an implement, and an assembly comprising a boom, a stick, and a coupling. The assembly is configured to define a heading {circumflex over (N)} and to swing with, or relative to, the chassis about a swing axis S. The stick is configured to curl relative to the boom about a curl axis C. The implement is coupled to a stick terminal point G via the coupling and is configured to rotate about a rotary axis R such that a leading edge of the implement defines a heading Î. An excavator control architecture comprises sensors and machine readable instructions to generate signals representative of {circumflex over (N)}, an assembly swing rate ω.sub.S about S, and a stick curl rate ω.sub.C about C, generate a signal representing a terminal point heading Ĝ based on {circumflex over (N)}, ω.sub.S, and ω.sub.C, and rotate the implement about R such that Î approximates Ĝ.

Automated control for excavators
Methods and systems related to operating an excavator during a digging cycle are described. In some embodiments, a nominal path of a bucket connected to one or more linkages of the excavator may be commanded. A correction to the commanded nominal path may be applied to maximize a power applied by at least one of the one or more linkages of the excavator during at least a portion of the digging cycle.
SYSTEM AND METHOD FOR CONTROLLING WORK MACHINE
A system controls a work machine that loads materials onto a conveyance vehicle. The system includes a controller and a detection device. The controller controls the work machine in an automatic control mode in which work is performed automatically. The detection device detects an approach of the conveyance vehicle toward the work machine. The automatic control mode includes a loading mode in which the work machine is caused to move to perform loading work for loading onto the conveyance vehicle, and an other mode other than the loading mode. The other mode includes at least one of a mode for gathering fallen materials and a digging mode for further increasing the materials by digging. The controller causes the automatic control mode to transition from the other mode to the loading mode when the approach of the conveyance vehicle is detected.
SHOVEL AND SYSTEM
A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a link unit attached to the upper turning body, and a processing circuitry configured to align an end of the link unit with an end attachment to be attached.
SHOVEL
A shovel includes a lower traveling structure, an upper swing structure swingably mounted on the lower traveling structure, and a hardware processor provided on the upper swing structure. The hardware processor is configured to recognize the position of a dump truck and create a target trajectory for a dumping operation.
WORK MACHINE, SYSTEM, AND METHOD OF CONTROLLING WORK MACHINE
A hydraulic excavator loads a load onto a loaded machine. The hydraulic excavator includes a work implement and a controller. The work implement includes a bucket. The controller senses an amount of natural lowering of the bucket in a stand-by state in which the hydraulic excavator waits for entry of the loaded machine and controls the work implement to raise the bucket based on the amount of natural lowering.
