摘要： A deslugging method and system for an agricultural combine, providing several semi- and fully automated operating modes or routines for removing or dislodging a slug of crop and/or other material from the threshing system and/or a feeder of the combine for conveying crop material to the threshing system. The routines can include reciprocating, agitating and jogging routines, which can be automatically altered during execution responsive to sensed or changing conditions, as processed by a suitable filter such as a simplified Kalman type signal filter, for generating a real time estimation and prediction of the various states of the threshing system.

摘要： An agricultural combine is provided with a controller that estimates a hydraulic pressure of a rotor drive system based upon the speeds of the pump (or engine) and motor that drive the rotor. The pressure is estimated by generating a pump displacement control signal in a convention feedback control algorithm and using that signal together with a sensed motor speed signal and a sensed pump speed (proportional to engine speed) to estimate the hydraulic pressure.

摘要： An agricultural combine includes a rotor drive system to which sensors are coupled to signal the rotational speed of a hydraulic motor and an engine. An electronic controller that contains a mathematical model of the system reads the sensors and using the model estimates additional parameters of the system. The estimated parameters include a gearbox's gear ratio and a planetary ring gear's speed. These estimated parameters and the sensor readings are used in a PID feedback control loop to control the speed of a planetary ring gear by controlling the speed of a hydraulic motor driving the sun gear. In this manner, the controller can drive the ring gear to a predetermined speed that reduces the difference in the input and output speeds of a hydraulic clutch and thereby engage that clutch while reducing shock to the clutch and other mechanical components of the combine.

摘要： A hydro-mechanical control system for an agricultural combine threshing rotor is operable 1) to transfer torque to the rotor so as to maintain rotor velocity within an acceptable range of a commanded velocity despite small fluctuations in rotor load and engine speed, 2) to reduce wear on mechanical components of the rotor drive system during rotor acceleration, 3) to employ the most efficient combination of mechanical and hydrostatic rotor drive characteristics during steady state operation of the rotor and 4) to reduce the likelihood of engine stall. The system includes a mechanical motor such as an engine, a hydrostatic motor, and a gearset disposed between both motors and the rotor. A clutch is operable to selectively couple the mechanical motor to the gearset, and a brake is selective operable to selectively arrest a driven gear of the gearset from rotation.

摘要： A method of calibrating the control current startup threshold in a proportionally controlled drive system for a work vehicle is disclosed. To determine a current threshold value for use in the system a control current exhibiting a relatively low value is first applied to the system. Subsequently, the steps of repetitively increasing the control current to a control current start value at which system motion starts and decreasing the control current to a control current stop value at which system motion substantially stops are repetitively conducted. The resultant control current start values and control current stop values are stored in a memory. The stored control current start values and control current stop values are is then averaged to determine a control current threshold value for use in controlling the system.
