Multi-vehicle coordinated grade control system
A coordinated multi-vehicle grade control system and method includes receiving, by a first controller onboard a first work vehicle, a first grade control signal. The method and system also include receiving, by a second controller onboard a second work vehicle, a second grade control signal. Additionally, the method and system include orienting, by a first actuator of the first work vehicle, the first grading implement with respect to the first work vehicle according to the first grade control signal. Furthermore, the method and system include orienting, by a second actuator of the second work vehicle, the second grading implement with respect to the second work vehicle according to the second grade control signal. The second grade control signal is based, at least in part, on the first grade control signal to coordinate the orientation of the first grading implement with respect to the second grading implement along the grading pass.
VALVE SYSTEMS AND METHOD FOR ENHANCED GRADING CONTROL
A valve system, including first, second, third and fourth ports, a first flow path connecting the first and second ports, a second flow path connecting the third and fourth ports, with valves connected in the first and second flow paths, and energizable to block the same. A third flow path connects the first and second ports and a fourth flow path connects the third and fourth ports. The third and fourth flow paths are more restricted than the respective first and second flow paths. A fifth flow path connects the first and fourth ports and a sixth flow path connects the second and third ports. When the third and fourth flow paths are open, the first, second, fifth, and sixth flow paths are blocked. When the first and second flow paths are open, the third, fourth, fifth, and sixth flow paths are blocked. When the fifth and sixth flow paths are open, the first, second, third, and fourth, flow paths are blocked.
CONTROL SYSTEM FOR WORK VEHICLE, CONTROL METHOD AND WORK VEHICLE
A control system for a work vehicle having a work implement includes a first operating lever for the work implement, a first operating member and a controller. The first operating member is provided on the first operating lever. The controller is configured to perform an automatic control of the work implement. The controller is configured to perform a function of the automatic control, which is allocated to the first operating member, in response to operating the first operating member when a performance condition, including that the first operating lever is located in a neutral position thereof, is satisfied.
System and method for moving material
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.
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.
ARRANGEMENT FOR CONTROLLING A WORK MACHINE
A method for controlling loading material to a bucket of a work machine from a stack of material is disclosed. The method includes the steps: of selecting a control profile to be used as a basic control profile including indications for positions of at least one of the bucket and the boom of the work machine as a function of a distance traveled by the work machine with reference to a reference location; obtaining information of a distance traveled by the work machine while loading material to the bucket; examining at least one condition regarding the work machine during loading; and determining, on the basis of the examined condition, whether another position than indicated by the selected control profile is to be used for at least one of the bucket and the boom.
Automated control of dipper swing for a shovel
Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.
METHOD FOR PRODUCING TRAINED WORK TYPE ESTIMATION MODEL, TRAINING DATA, COMPUTER-IMPLEMENTED METHOD, AND SYSTEM COMPRISING WORK MACHINE
A work is classified into a type with high accuracy. A method for producing a work type estimation model trained comprises: obtaining training data including a specific viewpoint image, as viewed from a specific viewpoint position, of a three-dimensional model representing a stereoscopic shape of a work machine at work, and a result of classifying a work into a type with which the specific viewpoint image is labeled and which indicates content of a motion of the work machine; and training the work type estimation model through the training data.
ENGINEERING MACHINERY EQUIPMENT, AND METHOD, SYSTEM, AND STORAGE MEDIUM FOR OPERATION TRAJECTORY PLANNING THEREOF
The present disclosure discloses an engineering machinery equipment, and a method, system, and storage medium for operation trajectory planning thereof, and relates to the field of artificial intelligence, automatic control, and engineering machinery technologies. A method can include: acquiring three-dimensional sensing data of a material pile, to construct a three-dimensional model of the material pile based on the three-dimensional sensing data; determining a loading operation position of the engineering machinery equipment on the material pile based on the three-dimensional model of the material pile and structural design information of the engineering machinery equipment; and acquiring position information of a mechanical structural component of the engineering machinery equipment, and performing operation trajectory planning based on the position information of the mechanical structural component and the loading operation position, to generate an operation trajectory of the mechanical structural component executing a material loading operation.
FORCE-BASED WORK VEHICLE BLADE PITCH CONTROL
A system and method for automatically adjusting blade pitch in crawler dozers, motor graders, and other bladed work vehicles includes estimating a current tractive force of the work vehicle utilizing one or more controllers that establish whether the current tractive force of the work vehicle can be reduced by rotating the blade to an optimized pitch angle. A command is transmitted from the one or more controllers to a blade actuation system to rotate the blade to the optimized pitch angle. The method may be performed iteratively to repeatedly adjust the blade pitch to optimized angles as the work vehicle operates and conditions affecting the optimal blade pitch angle vary.
