Abstract

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.

Abstract

A method of defining an end travel limit of an electric actuator includes sensing an electric current of the electric actuator while moving the electric actuator from a first position to a second position. A maximum travel current of the electric current sensed during movement of the electric actuator between the first position to the second position is increased by a factor to define a maximum calibration current. The electric current is then sensed while moving from the second position toward an end travel position of the electric actuator. Movement of the electric actuator is stopped at a fault position when the electric current equals the maximum calibration current. The end travel limit of the electric actuator is then defined as a function of the fault position.

Abstract

A device detects a trigger to dispense a product at a dispense point using a tool operably coupled to a tractor. In response to detecting the trigger, the device determines a delay time between commanding the tool to dispense the product and the product actually being dispensed, and determines a release point based on operating parameters of the tractor, the release point being a point at which the tractor is predicted to be an amount of time away from the dispense point equal to the delay time. The device determines that the tractor has reached the release point, and commands the tool to dispense the product, where the product reaches the dispense point based on the delay time.

Abstract

An implement management system detects implement wear and monitors implement states to modify operating modes of a vehicle. The system can determine implement wear using the pull of the implement on the vehicle, the force and angle of which is represented by an orientation vector. The system may measure a current orientation vector and determine an expected orientation vector using sensors and a model (e.g., a machine learned model). Additionally, the implement management system can determine an implement state based on images of the soil and the implement captured by a camera onboard the vehicle during operation. The system may apply different models to the images to determine a likely state of the implement. The difference between the expected and current orientation vectors or the determined implement state may be used to determine whether and how the vehicle's operating mode should be modified.

Abstract

Systems and methods for perfonning an engine regeneration procedure in a work machine with an internal combustion engine are described. An electronic controller determines, based on information associated with one or more machine sensors and/or machine actuators, whether the work machine is in an idle state (e.g., a storage or non- harvesting state). In response to determining that the work machine is in the idle state, the electronic controller displays a user approval prompt on the display of an operator interface and perfomis the engine regeneration procedure in response to receiving a user input approving the engine regeneration procedure after displaying the user approval prompt. Conversely, in response to determining that the work machine is not in the idle state, the electronic controller performs the engine regeneration procedure without displaying the user approval prompt and without receiving any user input approving the engine regeneration procedure.

Abstract

ABSTRACT OF THE DISCLOSURE A method of diagnosing a hydrostatic transmission system includes defining an initial charge pressure of a charge pump at a defined operating position of a primary pump. The primary pump is controlled to operate at the defined operating position. A current charge pressure from the charge pump is sensed when the primary pump is operating at the defined operating position. A pressure difference between the initial charge pressure of the charge pump and the current charge pressure of the charge pump is calculated and correlated to a system state of health of the hydrostatic transmission system.
