    摘要： Various embodiments of the present disclosure provide a guided line acquisition system and method for generating a path of a vehicle from its current location to a final guidance line. This path is referred to hereinafter as an acquisition path. The generated acquisition path starts at the current vehicle position and ends co-linear to the final guidance path. The acquisition path is generated using one constraint and one objective parameter. More specifically, the acquisition path is constrained by the minimum turning radius of the vehicle and angle of approach criteria, (i.e., the maximum heading relative to the guidance line). It should be appreciated that while the guided line acquisition system attempts to find an acquisition path that meets the angle of approach criteria, the guidance acquisition system will allow this objective to be sacrificed when it is not possible due to the minimum turning radius of the vehicle.

    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： A first sensor is associated with the first arm to provide a first sensor signal response indicative of a first position or first movement of the first arm with respect to the first row. A second sensor is associated with the second arm to provide a second sensor signal response indicative of a second position or second movement of the second arm with respect to the first row, or second row. A data processor is adapted to estimate a center point of the first row or a center point between the first row and the first row, or second row based on targeting substantial symmetry in the first sensor signal response and the second sensor signal response as an indication that a longitudinal axis of the vehicle is aligned with the center point, for example.

    摘要： A system and method are provided for controlling operation of earth working machines, e.g., scraper units configured to load, transport, and unload material depending on the respective work state. A design plan (e.g., a cut-fill map) is obtained corresponding to a working area to which the earth working machines are assigned. For each of the machines, the method further includes generating and/or selectively retrieving performance optimization data sets comprising a loading capacity and loading rates correlated to combinations of input data for working parameters for the respective machine, generating a work plan comprising a route of advance and corresponding work state transitions of the machine with respect to the working area, wherein the work plan is generated based at least in part on the performance optimization data sets and the design plan, and automatically controlling working parameters for the machine in accordance with the generated work plan.

    摘要： A reverse passive implement guidance system is provided for a work machine having a work vehicle configured to direct an implement coupled to the work vehicle via a steering system along a desired implement path. The reverse passive implement guidance system includes one or more vehicle sensors to collect vehicle position and orientation information; one or more implement sensors to collect implement position and orientation information; a controller coupled to the one or more vehicle sensors and the one or more implement sensors. The controller is configured to: receive the vehicle position and orientation information and the implement position and orientation; generate vehicle steering commands to drive the work vehicle such the implement is guided in a reverse direction onto or along the desired implement path; and execute the vehicle steering commands via the steering system of the work vehicle.
