Abstract: An agricultural combine has a variable displacement pump connected to four drive motors that drive four wheels. An electronic controller monitors the speed of each wheel and reduces the torque of the motor that drives the wheel when the wheel slips. The controller reduces the torque by reducing the specific displacement of the slipping motor. Once the wheel has ceased slipping, the controller increases the specific displacement of the motor back to its original displacement.

Abstract: 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.

Abstract: 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.
