  • Publication number: 20060112685
    Abstract: A control system for a work machine having a plurality of removably attachable work tools is disclosed. The control system has a tool recognition device configured to generate a recognition signal corresponding to each of the removably attachable work tools, and at least one fluid actuator configured to move at least one of the plurality of removably attachable work tools. The control system also has at least one fluid sensor configured to generate a load signal and at least one operator interface device configured to generate a desired velocity signal. The control system further has a controller in communication with the tool recognition device, the at least one fluid actuator, the at least one fluid sensor, and the at least one input device. The controller is configured to command a velocity for the fluid actuator in response to the recognition signal, the load signal, and the desired velocity signal.

  • Publication number: 20060090459
    Abstract: A hydraulic system has a source, a plurality of fluid actuators, and a controller. The controller is configured to receive an input indicative of which of the plurality of fluid actuators are a first and a second type of fluid actuator, to receive an input indicative of a desired flow rate for the plurality of fluid actuators, and to determine a current flow rate of the source. The controller is further configured to demand the desired flow rate for the first type of fluid actuator and to demand a scaled down desired flow rate for the second type of fluid actuator when a total desired flow rate exceeds the current flow rate of the source, and to demand a scaled down desired flow rate for all of the plurality of fluid actuators when the desired flow rate for the first type of fluid actuator exceeds the current flow rate of the source.
