    摘要： 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 ωS about S, and a stick curl rate ωC about C, generate a signal representing a terminal point heading Ĝ based on {circumflex over (N)}, ωS, and ωC, and rotate the implement about R such that Î approximates Ĝ.

    摘要： A payload monitoring system on a machine includes a payload sensor configured to generate a plurality of payload data corresponding to a payload amount in a bucket of a machine, the plurality including a first payload data and a second payload data and a controller. The controller is configured to receive the first payload data from the payload sensor and off-board payload data from an off-board system, compare the first payload data to the off-board payload data to generate a payload data offset, receive the second payload data from the payload sensor, and generate an adjusted payload data based on the second payload data and the payload data offset.

    摘要： Machine control systems for controlling a land levelling or earthmoving process of a wheel loader relative to a working plane are disclosed. In some embodiments, the wheel loader may be equipped with a land levelling or earthmoving blade and may comprise tool positioning means for adjusting the position and orientation of the tool relative to the first body. In some embodiments, the machine control system comprises a machine control unit and an orientation detection system. In some embodiments, the orientation detection system may include orientation detection means which are designed to be attached to the blade and/or to the wheel loader for detecting a position and an orientation of the blade relative to a working plane. In some embodiments, the orientation detection means are adapted to generate orientation data according to the relative position and orientation of the blade and to transmit the orientation data to the machine control unit.

    摘要： The present invention provides a control method and a control apparatus for a vehicle that make it possible to moderate or completely eliminate the impacts generated when the bucket is operated in a tilt direction, from a state in which the bucket in a dump position is forcibly actuated in the tilt direction and the bucket hydraulic cylinder is pressurized by the lifting operation of the boom and also to perform the boom lifting operation with good operability and workability. Control is performed to supply a pressure oil to the bucket hydraulic cylinder so as to actuate the bucket hydraulic cylinder in the tilt direction when a work equipment is being actuated in an actuation region close to an actuation region in which the bucket is forcibly actuated in the tilt direction by lifting the boom in a state in which the bucket is operated to a neutral position or dump operated, or when the bucket is being actuated in the tilt direction in the actuation region in which the bucket is forcibly actuated in the tilt direction. Further, a pressure oil supplied to the bucket hydraulic cylinder is controlled so as to restrict an actuation speed of the bucket hydraulic cylinder in a dump direction when [the work equipment] being actuated in an actuation region close to an actuation region in which the bucket is forcibly actuated in the tilt direction by operating the boom to a neutral position or lowering the boom in a state in which the bucket is dump operated.
