摘要： In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device, an MRF joystick resistance mechanism, and a controller architecture. The joystick device includes, in turn, a base housing, a joystick movably mounted to the base housing, and a joystick position sensor configured to monitor movement of the joystick relative to the base housing. The MRF joystick resistance mechanism is controllable to vary a first joystick stiffness resisting movement of the joystick relative to the base housing in at least one degree of freedom. The controller architecture is configured to: (i) detect when unintended joystick motion conditions occur during operation of the work vehicle; and (ii) when detecting unintended joystick motion conditions, command the MRF joystick resistance mechanism to increase the first joystick stiffness in a manner reducing susceptibility of the joystick device to unintended joystick motions.

摘要： A work vehicle that operates on a surface comprising an optical sensor. The optical sensor is configured to capture image data that includes a ground material. A non-transitory computer-readable memory is provided for storing operation information. An electronic processor is configured to receive image data captured by the optical sensor, apply an artificial neural network to identify a ground material characteristic based on the image data from the optical sensor, wherein the artificial neural network is trained to receive the image data as input and to produce as the output an indication of the ground material characteristic, access, from the non-transitory computer-readable memory, the operation information corresponding to the ground material characteristic, and adjust an operation of the work vehicle based on the accessed operation information corresponding to the ground material characteristic.

摘要： A counterweight removal protection system and a method of controlling removal of the counterweight to avoid damage to an imaging sensor system of a work vehicle, such as an excavator. The imaging sensor system includes an imaging sensor supported by the counterweight and configured to transmit an imaging sensor signal to a vehicle controller to determine the state of the imaging sensor signal. A user interface in the work vehicle includes a selectable touch button to enable removal of the counterweight depending on the state of the imaging sensor signal. An interlock device prevents lowering the counterweight based on the state of the imaging sensor signal. In one embodiment, the imaging sensor signal is a heartbeat signal.

摘要： A work machine having a traveling body, a moveable structure coupled to the traveling body, a sensor operable to generate a sensory signal, and a controller. The controller is in communication with the sensor. The controller including a processor and a memory having a position control algorithm stored thereon. The processor is operable to execute the position control algorithm to receive a boundary command establishing a defined boundary; receive a sensory signal from the sensor related to the movement of the movable structure; determine a position of the movable structure relative to the traveling body; and limit movement of one of the ground-engaging mechanism of the traveling body or the actuator of the moveable structure as the traveling body moves along the travel path when the position of the movable structure is within an allowable distance from the defined boundary.

摘要： A system includes calibrating a grade control system of a work vehicle having a controller operatively connected to a camera. A plurality of cylinders operative to move a blade on the vehicle. The blade includes one or more blade markers. One of the cylinders moves to a predetermined configuration that is between 0% and 100% of maximum stroke length, and the camera takes a corresponding image of the one or more blade markers. The controller measures a corresponding location of the one or more blade markers using the corresponding image and calibrates the grade control system based on the corresponding location of the one or more blade markers. The stored corresponding location can be an initial calibration location or a corresponding calibration location that was previously determined during operating conditions of the work vehicle. The grade control system is calibrated in real-time while the work vehicle is operating or stationary.
