ABSTRACT:
TECHNICAL FIELD
This invention relates generally to methods and systems for controlling electronically controlled sub-systems and, more particularly, to methods and systems for selecting a desired response of an electronic controlled sub-system associated with work machines.
BACKGROUND ART
Mechanically controlled machines have a disadvantage in that their characteristics are fixed into the design. For instance, in mechanically controlled earth moving machines, the relation between operator lever and implement speed is manufactured into the mechanisms that connect the lever motion to the mechanism that shifts the spool. Once built, that relationship is fixed and cannot be changed on the fly. Even the current generation of electronically controlled machines, wherein the characteristics are programmed in software, have fixed characteristics that cannot be altered on the fly, unless the code is changed and entered into the machine controller box.
A user of a machine, however, may not feel comfortable operating a machine with predetermined characteristics. Perhaps they are proficient in the use of the machine and prefer a different than what is designed into the machine. Such inflexibility may lead to production loss for that operator. Another situation in which a different response may be desired, is when a novice operator is operating a machine. A novice operator may be pushing the machine beyond its normal operating ranges, therefor, it may be desirable to have different responses to avoid damage to a machine.
Thus, there is a need for allowing an operator of a machine to select a desired response of an electronically controlled sub-system associated with a work machine.
The present invention is directed to overcome one or more of the problems as set forth above.
DISCLOSURE OF THE INVENTION
In one aspect of this invention, a method is provided for altering the machine sub-system behavior machine to suit a user's preference. The method includes storing a plurality of parameters associated with the operation behavior of the sub-system wherein the parameters have a set of values associated therewith. Each set of values define one of a plurality of acceptable operating behaviors for that sub-system. The method further includes receiving a selection signal selecting one of the set of values of the parameters, and controlling the sub-system based on the selected set of values for the parameters.
In another aspect of the invention, a system is also provided for carrying out the step of the above described method. The system includes a database for storing a plurality of parameters associated with the operating behavior of the sub-system wherein the parameters have sets of values associated therewith. Each set of values defines one of a plurality of acceptable operating behaviors for that sub-system. The system further includes a controller in communication with the database, for receiving a selection signal selecting one of the set of values of the parameter and controlling the sub-system based on the selected set of values of the parameters.
