摘要： An arm load control system for a work vehicle including a controller comprising a memory and a processor. The controller is configured to determine whether a lift arm is in a maximum load configuration based on a position of the lift arm relative to a chassis of the work vehicle and output a control signal to a propulsion assembly of the work vehicle indicative of instructions to adjust a tractive effort of the work vehicle based on whether the lift arm is in the maximum load configuration.

摘要： A work implement includes a support controller disposed in communication with a hydraulic lift cylinder. The support controller initiates a control activation signal for commanding movement of the hydraulic lift cylinder to move the head support from an initial start position to a commanded support position. The support controller determines a stop signal position based on the current rate of movement of the head support toward the commanded support position. The stop signal position may further be based on a current fluid pressure of an associated float system. The support controller ceases or stops the control activation signal when the head support reaches the stop signal position, whereby the head support decelerates over a distance after cessation of the control activation signal such that the head support substantially stops movement at the commanded support position.

摘要： A method for machine grade assist includes determining whether user input will cause an implement of a machine to dig below a desired grade. User input to move a stick of an excavator can be blocked and/or delayed using hydraulic pressure so that movement of both the stick and the boom of the excavator can be synchronized to prevent a bucket of the excavator from digging below a desired grade when the stick is moved.

摘要： A work vehicle may include a chassis, a ground-engaging blade, a first sensor, a second sensor, and a controller. The blade may be movably connected to the chassis via a linkage assembly configured to allow the blade to be raised and lowered and moved in a roll direction. The first sensor may be configured to provide a chassis inclination signal indicative of a main fall angle, a chassis roll signal indicative of a cross slope angle, and a chassis heading signal. The second sensor may be configured to provide a blade inclination signal and a blade roll signal. The controller may be configured to receive the signals, determine a target grade, determine a distance error based on the signals indicative of a distance between the blade and the target grade, and send a command to move the blade toward the target grade based on the distance error.

摘要： Work machines and methods and systems to control and determine a position of an associated implement are disclosed. An example work machine including a first vehicle component movable relative to a second vehicle component; and a processor to: cause the first vehicle component to move toward a commanded position; predict a first position of the first vehicle component of the work machine using first processes; determine a second position of the first vehicle component using second processes; and in response to a difference between the first position and the second position, to cause the first vehicle component to move further toward the commanded position to correct for the difference.

摘要： An estimate of the relative attitude between an implement and a vehicle body is computed from a body angular velocity measurement received from at least one body gyro mounted on the vehicle body and from an implement angular velocity measurement received from at least one implement gyro mounted on the implement. A first system state vector estimate corresponding to a first time instant includes a representation of a first relative attitude estimate. An updated system state vector is computed based at least in part on the first system state vector estimate, the body angular velocity vector measurement, and the implement angular velocity vector measurement. A second system state vector estimate corresponding to a second time instant is predicted based at least in part on the updated system state vector and a time-dependent system model. The second system state vector estimate includes a representation of a second relative attitude estimate.

摘要： A rollered grading assembly, including an elongated roller drum, an axle extending through the drum, an elongated housing partially enclosing the drum and connected to the axle, an elongated blade connected to the housing, a pivot rod perpendicular to the axle and connected to the housing, a coupler connected to the housing, and a pivot actuator connected to the coupler and housing. The coupler has a proximal end connected to the housing portion and positioned adjacent the roller drum and a spaced distal end extending away from the housing. Movement of the distal end a first distance while the proximal end remains stationary urges the housing to pivot around the drum and move the blade portion a second, shorter distance into a desired position relative grade.

摘要： A motor grader having a moldboard and tiltable wheels is provided with a sensor system and electronic controller for determining a required wheel tilt to overcome anticipated draft forces resulting from the angle to which the moldboard is adjusted. The wheels are automatically leaned as determined necessary for counteracting the draft forces. An all-wheel-drive system can be controlled together with wheel lean for counteracting draft forces. Inputs from moldboard tilt and roll, motor grader positioning and orientation and the like can be included in determining anticipated draft forces.

摘要： A work vehicle may include a chassis, a ground-engaging blade, a sensor assembly, and a controller. The blade may be movably connected to the chassis via a linkage assembly configured to allow the blade to be raised and lowered relative to the chassis. The sensor assembly may be configured to provide a chassis inclination signal indicative of an angle of the chassis relative to the direction of gravity and a blade inclination signal indicative of an angle of the blade relative to one of the chassis and the direction of gravity. The controller may be configured to receive the chassis and blade inclination signals, determine a target grade, determine a distance error based on the signals indicative of a distance between the blade and the target grade, and send a command to move the blade toward the target grade based on the distance error.

摘要： Disclosed is a method for mapping network identifiers to a set of sensor modules that measure a three-dimensional action vector and that are sensitive to orientation in three-dimensional space. Each sensor module is mounted at a different position on a machine such that the orientation of each sensor module is different. The method includes one or two stages. In the first stage, the machine is placed in a stationary state, and measurements of a static action vector from a sensor module identified by a network identifier are correlated with expected measurements from a sensor module having a corresponding orientation and corresponding position. In the second stage, the machine is placed in a dynamic state, and measurements of a dynamic action vector from a sensor module identified by a network identifier are correlated with expected measurements from a sensor module having a corresponding orientation and corresponding position.
