Abstract: A method and system for controlling the steady-state speed of a cylinder in an electrohydraulic system having multiple cylinders includes a plurality of levers for controlling each of the cylinders. A controller, in communication with the levers and the hydraulic cylinders, has a limited number of parameters defining at least one desired relationship between steady-state speed and lever position for each of the cylinders stored therein. The controller further determines a current desired relationship for each of the cylinders from the associated at least one desired relationships. Upon detecting movement of the lever, the controller determines a current position of the lever associated with one of the cylinders and then controls the steady-state speed of the associated cylinder based on the limited number of parameters defining the current desired relationship and the position of the lever.

Abstract: A control system implements several methods for automating work functions of a machine. Single activation of an operator switch generates a command to automatically perform a desired work function. A controller determines whether conditions are satisfactory to perform the desired function. When the conditions are satisfactory, the work function is performed automatically without requiring the operator to manipulate levers that are otherwise used to control the work implement of the machine.

Abstract: A method and system for altering operating behavior of a sub-system component of a machine to suit a user's preference includes a database for storing a plurality of parameters associated with the operating behavior of the sub-system component. The parameters have sets of values associated therewith wherein each set of values define one of a plurality of acceptable operating behaviors for the sub-system component. A sub-system controller receives a selection signal from the operator via a user interface selecting one of the set of values of the parameters according to his/her preference. The sub-system controller then controls the sub-system component based on the selected set of values for the parameters.
