摘要： A system includes a work implement sensor attached to a work implement to detect work implement roll and pitch angles, and a controller. The controller acquires an actual frame length, a position of the first body connecting portion, and the roll and pitch angles. The controller calculates an assumed position of the first frame connecting portion when the yaw angle is assumed to be a predetermined angle based on the roll and pitch angles in the first posture, an assumed frame length indicating a distance between the assumed position of the first frame connecting portion and the first body connecting portion, the yaw angle of the work implement in the first posture based on a difference between the actual and assumed frame lengths, and a position of the predetermined portion of the work implement based on the roll, pitch and yaw angles of the work implement in the first posture.

摘要： A work machine is provided with grade control capability using an imaging system, e.g., rather than GPS. The work machine includes at least one work implement for working at least part of a terrain, and first sensors (e.g., cylinder sensors) generate signals corresponding to positions of the work implement. Second sensors (e.g., stereo cameras) generate signals corresponding to positions of representative features of the terrain (e.g., curbs) in a field of view. A controller receives the signals and determines in a local reference system independent of a global reference system: first position information corresponding to the work implement; and second position information corresponding to the representative features. According to a selected control mode, target parameters for the work implement are determined based on the second position information corresponding to the representative features, and output signals are generated corresponding to a difference between the first position information and the target parameters.

摘要： The present disclosure provides methods for adjusting steering angle and articulation angle in an auto steering operation of a work vehicle. The percentage of travel of an articulation joystick of the work vehicle at least partially determines an articulation desired angle change, which can be used to calculate an articulation desired angle and a steering desired angle change. The difference between the articulation desired angle and an articulation angle detected by an articulation angle sensor is used to adjust the articulation angle. The steering desired angle change can be used to calculate a steering desired angle. The difference between the steering desired angle and a steering angle detected by a steering angle sensor is used to adjust the steering angle.

摘要： A system and method are provided for work cycle tracking for a self-propelled work vehicle having an integrated or drawn/pushed implement, for example comprising a scraper, and a loading container for receiving material worked thereby. First sensors generate data corresponding to operating parameters of the work vehicle, and second sensors generate data corresponding to operating parameters of the implement. Data storage includes, for each of various work states associated with the work cycle, correlations between operating parameters, of the work vehicle and/or implement, and a start or completion of the respective work state. A controller determines a current work state of the various work states associated with the work cycle based on current input data from the first and second sets of sensors, with respect to the stored correlations, and generates one or more output signals based on the determined work state.

摘要： An operation control method for controlling operation of a plurality of construction machines that perform excavation while moving is described. Because a moving speed of a second construction machine at a time of excavation and an excavation time of the second construction machine are set based on a moving speed of a first construction machine at a time of excavation and an excavation time of the first construction machine, it is possible to achieve efficient excavation work with good usability.

摘要： A work vehicle includes a work implement. A control system for the work vehicle includes an operating device and a controller. The operating device outputs an operation signal indicative of an operation by an operator. The controller communicates with the operating device and controls the work implement. The controller determines a first target design topography. The controller generates a command signal to operate a work implement in accordance with the first target design topography. The controller obtains a displacement amount of the work implement with respect to the first target design topography upon receiving the operation signal indicative of the operation of the work implement during work in accordance with the first target design topography. The controller determines a second target design topography based on the displacement amount. The controller generates a command signal to operate the work implement in accordance with the second target design topography.

摘要： 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.

摘要： A ramping subsystem of a control system for a dual path electronically controlled hydrostatic transmission is used to modify the commanded rate of change of pump and motor acceleration, deceleration and direction change command (performed to command machine motion from forward to reverse or vice versa) in order to achieve desired machine performance and operator feel. Pump and motor acceleration, deceleration and direction change command rates are then further modified using scaling tables based on selected maximum machine speed using operator input device.
