摘要:
Apparatus and a method for monitoring the performance of control algorithms, and inappropriate operator actions, and for providing failsafe deceleration for a vehicle, particularly an agricultural windrower, wherein the propulsion driveline of the vehicle is controllably and actively decelerated. Inappropriate operator actions can include, but are not limited to, attempted engagement of the park brake when operating in a high speed range. Control algorithm fault conditions can include, for instance, input commands changing at a rate beyond a predetermined threshold, and mismatch between operator control devices such as a FNR lever and a neutral switch.

Apparatus and a method providing a park brake for a propulsion system of an agricultural windrower having a FNR lever assembly including a FNR lever movable in relation to a neutral position in first and second directions, and a sensor for sensing positions of the FNR lever as the lever is moved and outputting signals representative thereof, the sensor being configured such that the signals outputted thereby are to have signal values within a predetermined range of values and/or which will change within a predetermined rate of change, a programmable control module in operative control of a park brake and programmed and operable for monitoring the signals and comparing the values of the signals to the predetermined range, and if the value of any of the signals is outside of the predetermined range, then automatically engaging the park brake.
摘要:
Apparatus and a method for monitoring the performance of control algorithms, providing a safeing subsystem for a vehicle, particularly an agricultural windrower, for determining when a controlled system such as the propulsion system is no longer tracking a reference input signal sufficiently well. An appropriate action can then be executed, such as outputting a fault signal and/or shutting down the controlled system. An exponentially decaying integrator can be used to monitor the tracking errors.

摘要:
A method for controlling and modifying the drop rate of a header on an agricultural harvesting machine by providing a programmable electronic control unit capable of receiving operator input through an input device. The programmable electronic control unit generates output signals based on the operator input to raise and lower the header according to a corresponding output drop rate signal.
摘要:
A hydraulic lift/flotation system for the header of a crop harvesting machine wherein each side of the header is supported by a single cylinder, which performs both the flotation and lift functions. For even lifting and flotation of an unbalanced header, each cylinder has its own control valve, pump, and accumulator. The operator sets the desired flotation force by actuating rocker switches; one switch position allows hydraulic oil to enter an accumulator to reduce header contact force with the ground. The other position allows oil to exit the accumulator to increase header contact force with the ground. To evenly float an unbalanced header, separate switches adjust each side independently. Once the flotation forces are set, the control valves will return to this preset flotation condition whenever float mode is selected, regardless of subsequent header lift and lower operations.
摘要:
A method and apparatus for automatically controlling a header lift system of an agricultural harvesting machine, particularly a windrower, to put a header of the machine into a transport mode wherein the header is raised to an elevated transport position, under certain specific conditions. Such conditions can include, but are not limited to, the machine operating in a high-speed range, the header not operating, the speed of the machine being above a predetermined level, and the last inputted control command being a header raise command. When in the transport mode, the lift system can also be operated in a float mode. Further, the header lift system can be returned to a normal mode when certain criteria are present for doing so.

The apparatus is a stepping reversing control for automated bale wagons in which an individual stack pattern is selected from a list by stepping through the list in a single direction by use of a pushbutton. The reversing control measures the interval for which the pushbutton is activated and reverses the direction of the stepping if the time the pushbutton is held down exceeds a prescribed time. A second control selects values from the list and generates a smaller favorites list and automatically makes all selections from only the favorites list.

A visual steering wheel direction indicator for a self-propelled machine. The indicator may additionally exhibit an indicator of the amount that the steering wheel must be turned in order to reach neutral. The indicator may be integrated into a neutral start system.
摘要:
An apparatus and method for calibration of an FNR lever or multifunction handle (MFH), wherein signal outputs as the FNR lever or MFH is transitioned to and from the neutral position and through at least one range of propulsion positions, are determined. The determined signal values are then compared with benchmark values for the same positions and movements, to determine whether the values are within expected norms. If not, it is determined that a fault condition exists. The operator is also prompted to input acknowledgments when the FNR lever or MFH is at the fully rearward and fully forward positions, to enable the calibration of the lever. Signal values outputted by a neutral switch are sensed when the lever or MFH is initially moved to the neutral position, and at a predetermined time thereafter, to test an associated propulsion enable or latch relay which is configured for providing a predetermined output for a predetermined time after movement of the lever or MFH into the neutral position, to allow for transitioning of the propulsion system to neutral operation.
