Forage harvester with automatic detection of receiving vehicle
A sensor detects a variable indicative of a position of a receiving vehicle relative to a harvester during a harvester operation in which a material conveyance subsystem on the harvester is conveying harvested material to the receiving vehicle. If the receiving vehicle is in a compromised position in which it is out of range of the material conveyance subsystem or is about to be out of range, then a control signal is generated that can alert the operator of the harvester, automatically control harvester speed, or perform other control operations.
Track assembly with electric motor
A vehicle includes a chassis, an engine coupled to the chassis, a power source coupled to the chassis, and a track assembly. The track assembly includes an electric motor coupled to the chassis, a first drive wheel coupled to the electric motor and pivotally coupled to the chassis, a second drive wheel coupled to the engine and pivotally coupled to the chassis, and a track engaging the first drive wheel and the second drive wheel. The engine is configured to provide mechanical energy to the second drive wheel to drive the track and propel the vehicle. The electric motor is configured to receive electrical energy from the power source and provide mechanical energy to the first drive wheel to drive the track and propel the vehicle.
OPERATOR COMMANDED PLACEMENT FOR CONTROL OF FILLING MECHANISMS
An agricultural harvester has a frame and a spout that is mounted to the frame. A display shows a representation of harvested crop in a receiving vessel. A control system detects an operator input selecting a portion of the receiving vessel and automatically controls a fill control system to being filling the receiving vessel, at the selected portions of the receiving vessel, with harvested material.
Autonomous Travel System for Work Vehicle
This autonomous travel system for a work vehicle is provided with an autonomous travel control unit. The autonomous travel control unit is capable of using a positioning system to cause a work vehicle to travel autonomously along a travel path including a turning path and a work path in which work is performed by a work unit. The work vehicle is provided with a vehicle speed control unit for controlling the vehicle speed and a vehicle speed operation unit for manipulating the vehicle speed. The vehicle speed control unit is capable of executing vehicle speed maintenance control in which even when operating force applied to the vehicle speed operation unit is released, the vehicle speed of the work vehicle corresponding to the operating position of the vehicle speed operation unit prior to release is maintained. The autonomous travel control unit allows vehicle speed maintenance control by the vehicle speed control unit when the work vehicle is being made to travel autonomously along the work path and prohibits vehicle speed maintenance control by the vehicle speed control unit when the work vehicle is being made to travel autonomously along the turning path.
Feedforward mechanism with signal decay for torque adjustment in diesel engine operation
Systems and methods of controlling operation of a diesel engine using feedforward load anticipation. An electronic controller determines a difference between an actual engine speed value of the diesel engine and a desired engine speed value, and generates a feedback control command based on the determined difference. In response to detecting one or more conditions indicative of an anticipated mechanical load event that will alter a total mechanical load of the diesel engine, the electronic controller applies a feedforward offset to the feedback control command in accordance with a feedback offset function. The feedback offset function causes the magnitude of the feedback offset to decrease over a period of time until the offset returns to zero (i.e., a signal decay function). The diesel engine is then operated based on the feedback control command and the feedforward offset.
Image selection for machine control
A vegetation index characteristic is assigned to an image of vegetation at a worksite. The vegetation index characteristic is indicative of how a vegetation index value varies across the corresponding image. The image is selected for predictive map generation based upon the vegetation index characteristic. The predictive map is provided to a harvester control system which generates control signals that are applied to controllable subsystems of the harvester, based upon the predictive map and the location of the harvester.
SYSTEM FOR COORDINATING CONTROL OF MULTIPLE WORK VEHICLES
A control system includes a controller configured to determine a target speed between a first target position of a haul vehicle relative to a harvester and a second target position of the haul vehicle relative to the harvester based on a flow rate of agricultural product through a conveyor of the harvester. The haul vehicle is coupled to a storage compartment, an outlet of the conveyor is aligned with a first unloading point within the storage compartment while the haul vehicle is positioned at the first target position, and the outlet of the conveyor is aligned with a second unloading point within the storage compartment while the haul vehicle is positioned at the second target position. Furthermore, the controller is configured to output a control signal indicative of instructions to direct the haul vehicle from the first target position to the second target position at the target speed.
PREDICTIVE MAP AND MACHINE CONTROL
A predictive map including predictive values of an agricultural characteristic of a worksite is obtained. An in-situ value of the agricultural characteristic is identified based on a sensor signal provided by an in-situ sensor. A corrected predictive map, including corrected predictive values of the agricultural characteristic, is generated based on the in-situ value of the agricultural characteristic. A controllable subsystem of a work machine is controlled based on the location of the work machine and the corrected predictive map.
Vehicle control system with track temperature sensing
A work vehicle may include a load sensor, an engine, a drive train driven by the engine and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further comprise a temperature sensor configured to sense a temperature and a vehicle control system configured to receive the sensed temperature and a vehicle load from the load sensor. The vehicle control system is configured to output a work speed vehicle alert based upon a combination of the temperature sensed by the temperature sensor and the vehicle load sensed by the load sensor.
State machine for multiple input-multiple output harvester control
An overall machine operational state (such as a problem state, field state, machine state, other non-problem state, etc.) is identified, and exit and entry conditions are monitored to determine whether the machine transitions into another operational state. When the machine transitions into a problem state, a multiple input, multiple output control system uses a state machine to identify the problem state and a solution is identified. The solution is indicative of machine settings that will return the machine to an acceptable, operational state. Control signals are generated to modify the machine settings based on the identified solution.
