  • Patent number: 8058829
    Abstract: An electronic control module for a machine may include instructions for performing a method. The method may include obtaining a total torque load limit for one or more hydrostatic transmission loops in the machine. The method may also include allocating the total torque load limit between the one or more hydrostatic transmission loops in the form of one or more lower level torque load limits.
    Type: Grant

  • Patent number: 7795752
    Abstract: A method for distributing power generated by a power generation system may include determining available power that can be generated by the power generation system. The method may also include obtaining power requests from power transforming devices, comparing the available power to the power requests, and determining amounts of the available power to distribute to the power transforming devices. The method may further include obtaining operating condition requests from the power transforming devices, and determining the operating conditions under which the power generation system should operate.

  • Publication number: 20100154403
    Abstract: A control for a variable displacement pump disposed in a hydraulic system obtains a requested signal from a manual control device and provides a command signal to a valve operating to adjust a displacement setting of the variable displacement pump. The control provides the command signal based on the requested signal, and scales the requested signal based on a sensed or calculated load of the system.

  • Publication number: 20090319136
    Abstract: A machine may include a torque producing system, and a torque consuming device including load controls operable to generate a request for torque. The machine may also include a control system coupled to the torque producing system and the load controls. The control system may be operable to receive the request for torque, determine a torque limit based on the requested torque, and communicate the torque limit to the load controls, the load controls being operable to adjust operation of the torque consuming device based on the torque limit.

  • Publication number: 20090140574
    Abstract: A method for distributing power generated by a power generation system may include determining available power that can be generated by the power generation system. The method may also include obtaining power requests from power transforming devices, comparing the available power to the power requests, and determining amounts of the available power to distribute to the power transforming devices. The method may further include obtaining operating condition requests from the power transforming devices, and determining the operating conditions under which the power generation system should operate.
