  • Publication number: 20200048866
    Abstract: A computerized method for adjusting machine capabilities of a machine in response to machine operating conditions is provided. The computerized method is carried out by a controller and includes: collecting data corresponding to the machine operating conditions using the controller. The data includes current machine health data, current operator skill level data, and current environmental factor data. The computerized method also includes comparing the machine operating conditions against stored metrics using the controller. When the machine operating conditions are below the stored metrics, the controller decreases the machine capabilities. When the machine operating conditions are above the stored metrics, the controller increases the machine capabilities.

  • Publication number: 20120233992
    Abstract: A wheel end assembly comprises a wheel hub support housing and a wheel hub drive assembly rotatably connected to the wheel hub support housing. The wheel end assembly also includes a hydraulic motor operatively coupled to the wheel hub drive assembly, the hydraulic motor being disposed to deliver a torque to the wheel hub drive assembly. The wheel end assembly further includes a pump, fluidly coupled to the wheel hub drive assembly and the hydraulic motor, the pump being disposed to provide a flow of hydraulic fluid to the wheel hub drive assembly.

  • Patent number: 7881841
    Abstract: A motion-control system includes an operator interface with an operator-input member and a controllable force feedback device drivingly connected to the operator-input member. The motion-control system may also include controls that regulate the motion of one or more moveable components, including adjusting a first operating parameter in a manner that depends at least in part on a control error between a target value of a second operating parameter and an actual value of the second operating parameter. The target value of the second operating parameter may be based at least in part on the motion of the operator-input member. The controls may also operate the controllable force feedback device to provide feedback force on the operator-input member in a manner that depends at least in part on the control error and such that the derivative of the feedback force with respect to the control error varies dependent at least in part on the control error.

  • Patent number: 7206681
    Abstract: A vibration management system for a work machine may include at least one machine component configured to respond to input commands from an operator of the machine. One or more vibration sensors may be configured to output a signal indicative of a vibration level experienced by the operator. A controller may be configured to monitor the output signal from the one or more vibration sensors and determine an average vibration level experienced by the operator. The controller may also be configured to monitor the input commands from the operator and calculate a predicted response of the at least one machine component to at least one of the input commands. The controller may also be configured to determine a predicted vibration effect on the operator based on the predicted response and adjust an actual response of the at least one machine component to the at least one operator input command based on the predicted vibration effect and the average vibration level.
