摘要： A path control systems and methods are disclosed that can aide in keeping an autonomous vehicle on a path. A current estimate of the autonomous vehicle's first position (x, y), heading, and velocity as well as a path of interest (e.g., breadcrumbs, line-arcs, or clothoid segments each containing velocity information) can be used to output a command velocity, command curvature, and/or a vector of waypoints. The command velocity, command curvature, and/or a vector of waypoints can be followed to move the autonomous vehicle from the first position onto the path of interest. An obstacle map may also be used to provide a path to the path of interest that avoids the obstacles on the obstacle map.

摘要： In one embodiment a method includes storing in non-volatile memory a library of equipment configuration code files, each equipment configuration code file including configuration code for configuration and control of a work vehicle, for configuration and control of an attachment to be carried or towed by the work vehicle, or for combined configuration and control of both the work vehicle and the attachment in combination, receiving an altered version of at least one equipment configuration code file, the altered version including OEM data provided by or altered by an original equipment manufacturer of the work vehicle or the attachment, dealer or distributor data provided by or altered by a dealer or distributor of the work vehicle or the attachment, and user data provided by or altered by a user of the work vehicle or attachment, and storing the altered version in the non-volatile memory of the library.

摘要： An autonomous vehicle is disclosed. The autonomous vehicle may include a sensor array; an engine output control system; a braking control system; and a controller. The controller may be communicatively coupled with the sensor array, the engine output control system, and the braking control system. The controller may be configured to: sense an environment with the sensor array to produce sensor data; receiving autonomous vehicle state data; determining whether the autonomous vehicle state data is above a threshold state value; in the event the autonomous vehicle state data is above a threshold state value, not using the sensor data to operate the autonomous vehicle; and in the event the autonomous vehicle state data is not above a threshold state value, using the sensor data to operate the autonomous vehicle.

摘要： Vehicle dispatch system includes upper stage unit, lower stage unit and interface communication unit. The upper stage unit, configured to generate vehicle schedules, is communicatively connected to the interface communication unit. The lower stage unit, communicatively connected to the upper stage unit and the interface communication unit, has two storage units and a control unit. The first storage unit stores in a state representation multiple possible states having multiple possible actions. The control unit, which receives the schedule as a state representation, is configured to simulate states during an episode by selecting a state action and determining a reward value. The second storage unit stores the reward value and has a policy linked to one possible action for each state. The interface communication unit, operable to receive and transmit vehicle communications, is configured to access the policy and its associated action and communicate the action to a vehicle.

摘要： Some embodiments include an autonomous loader comprising a speed control system; a steering control system; a shovel control system; and a controller communicatively coupled with the speed control system, the steering control system, and the shovel control system. In some embodiments, the controller has code that instructs the shovel control system to place the shovel in a position to load the shovel; instructs the speed control system to move the autonomous loader into a load zone; determines whether the shovel has been filled with material from the load zone; instructs the shovel control system to raise the shovel a predetermined amount; determines a second time whether the shovel has been filled with material from the load zone; instructs the shovel control system to raise the shovel out of the load zone; and instructs the shovel control system to shake the shovel.

摘要： A method for dispatching a plurality of vehicles operating in a work area among a plurality of destination locations and a plurality of source locations includes implementing linear programming that takes in an optimization function and constraints to generate an optimum schedule for optimum production, utilizing a reinforcement learning algorithm that takes in the schedule as input and cycles through possible environmental states that could occur within the schedule by choosing one possible action for each possible environmental state and by observing the reward obtained by taking the action at each possible environmental state, developing a policy for each possible environmental state, and providing instructions to follow an action associated with the policy.

摘要： A vehicle system includes at least one sensor and a communications system configured to receive one or more remote operations commands. The vehicle system further includes control system configured to execute a speed control system to control a speed of the vehicle system. The control system is further configured to execute an automatic adjustment teleoperations system to derive a filtered speed command based on the one or more remote operations commands and the at least one sensor, and to adjust the speed of the vehicle system based on the filtered speed command.

摘要： Some embodiments of the invention include a method for updating an occlusion probability map. An occlusion probability map represents the probability that a given portion of the sensor field is occluded from one or more sensors. In some embodiments, a method may include receiving field of view data from a sensor system; producing a probabilistic model of the sensor field of view; and updating an occlusion probability map using the probabilistic model and field of view data.

摘要： The present disclosure provides systems and methods that measure crop residue in a field from imagery of the field. In particular, the present subject matter is directed to systems and methods that include or otherwise leverage a machine-learned crop residue classification model to determine a crop residue parameter value for a portion of a field based at least in part on imagery of such portion of the field captured by an imaging device. Furthermore, principal components analysis, such as projecting image patches onto Eigen-images, can be performed to reduce the dimensionality of the feature vector provided to the classification model.

摘要： A work vehicle includes a roof panel forming a portion of a cab of the work vehicle. The work vehicle also includes a headliner disposed between the roof panel and an interior of the cab. In addition, the work vehicle includes a spatial locating antenna positioned between the roof panel and the headliner, such that a top side of the roof panel is positioned above the spatial locating antenna relative to a ground surface. Furthermore, the top side of the roof panel extends beyond a lateral extent and a longitudinal extent of the spatial locating antenna.
