Agricultural work system
An agricultural work system has an agricultural work machine to which at least one mounted implement can be fitted via at least one implement interface. A work machine configuration is associated with the work machine, and a mounted implement configuration is associated with the mounted implement. A drive unit is provided which acts via a drivetrain on ground engaging elements, particularly on tires. A system control and a control/display unit associated with the work machine are provided. It is proposed that the system control is adapted to determine the mounted implement configuration, to calculate the implement interface load transmitted via the implement interface based on the determined mounted implement configuration, and to evaluate and/or optimize the work machine configuration based on the calculated implement interface load.
YIELD MAP GENERATION AND CONTROL SYSTEM
One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.
SYSTEM AND METHOD FOR CONTROLLING AN AGRICULTURAL TOOL TOWED BY A PIVOTALLY ATTACHED VEHICLE BASED ON FUTURE PATH PREDICTION
A computer-implemented method, related system, and computer program product are provided for controlling an agricultural tool towed by a pivotally attached vehicle. A computer stores a model of the position and heading of the tool and the vehicle. The computer determines a velocity and turn rate of the vehicle based on position data from a first GPS receiver attached to the vehicle. The computer calculates the modeled position of the vehicle and the tool at a future time based on the velocity and turn rate of the vehicle. The computer also corrects the modeled position and heading of the vehicle and tool, based on position data from the first GPS receiver, and from a second GPS receiver attached to the tool, respectively. The computer generates a control signal to control an actuator associated with the tool based on the modeled position of the tool at the future time.
Self-Propelled Agricultural Work Machine
A self-propelled agricultural work machine comprising: an energy source; a ground engaging element configured with a drive train, the ground engaging element further configured to be driven in a normal operating mode by at least one of the energy source and drive train; a carrying frame supported on the ground engaging element; and a control unit in communication with an actuator associated with the agricultural work machine and the ground engaging element, the control unit configured to transmit signals so as to specify a steering angle of the ground engaging element and, in the event of a failure of at least one of the energy source or the drive train, the control unit configured to operate in a towing mode in which the control unit controls the actuator based on the signals from a sensor so as to detect the angle between a tow bar, a towing vehicle and the agricultural work machine that is being towed by the towing vehicle.
System and method for controlling the operation of an agricultural implement being towed by a work vehicle
In one aspect, a system for controlling an operation of agricultural implements may include a work vehicle configured to tow an implement. The work vehicle may include a hitch assembly having a draw point configured to be coupled to the implement. The work vehicle may further include an actuator configured to move the draw point relative to the hitch frame to adjust the position of the implement relative to the work vehicle. The implement may include a sensor configured to detect an operational parameter indicative of the operation of the implement. Additionally, the implement may further include a controller communicatively coupled to the sensor, with the controller being configured to initiate control of an operation of the actuator based on sensor data received from the sensor to adjust the operational parameter of the implement.
Method and control system for limiting vehicle turning radius
The turning radius of a differentially steered vehicle towing a trailer is controlled when turning so that its turning radius is greater than a minimum allowable turning radius. The turning radius may be autonomously adjusted using a controller to monitor the instantaneous rotational speed differential between the driven wheels and increase or decrease the relative speed between the wheels when the instantaneous rotational speed differential exceeds a threshold rotational speed differential, indicating a turn which is too tight. Alternately, the turning radius may be controlled by the vehicle's operator, who receives a signal from the controller indicating that the vehicle's turning radius is less than the minimum allowable. The operator may then take action to enlarge the turning radius using manual controls.
PRE-CHARGING TECHNIQUE FOR DISPENSING PRODUCT FROM TRACTOR TOOL PRIOR TO REACHING PLANT SITE
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.
DETERMINING VEHICLE HEADING AND IMPLEMENT HEADING OF LOW SPEED FARMING MACHINE
A system and a method are disclosed for determining a heading of a vehicle and a heading of an implement of a farming machine when the farming machine is stationary or moving at a speed below a threshold speed. The vehicle and the heading are attached together via a pivot hitch. A farming machine management system receives coordinates from a first location sensor coupled to the vehicle and a second location sensor coupled to the implement. The farming machine management system determines intersection points between a first circle centered at the first location sensor and a second circle centered at the second location sensor. The farming machine management system selects one of the intersection points based on an output of a machine learning model. The farming machine management system determines the headings of the vehicle and the implement and generates instructions for operating the farming machine based on the headings.
Method to prevent drift of an agricultural implement
A method to prevent drift in an agricultural implement. Drift is when one side of an agricultural implement is further behind or further ahead of the other side of the agricultural implement in a direction of travel. Drift can be controlled by increasing a downforce on the side that is further ahead, decreasing force on the side that is further behind, or a combination of both. The force can be a moment of force.
Winged Agricultural Implement with Steerable Transport Wheels
A towable agricultural implement, having a center frame and two wing frames pivotally coupled on the center frame to move between a field frame position extending laterally outward and a range of transport positions extending generally rearward, further includes a transport wheel on each wing frame that is pivotal about an upright steering axis through a range of wheel positions including a neutral transport wheel position for rolling forwardly. Each transport wheel is pivotal from the neutral transport wheel position in either one of two opposing steering directions under control of a steering actuator through an overall range of greater than 90 degrees. The wheels can be steered in a common direction during transport. A control system can also attempt to maintain a constant angle between the center section and the wings to allow reversing while in transport mode.
