  • Patent number: 10544565
    Abstract: A system for proactively controlling a rimpull limit of a machine includes a hydraulic system having a lift cylinder to move an implement; a lift cylinder pressure sensor that senses a hydraulic pressure of the lift cylinder and responsively produces a lift cylinder pressure signal; and a controller in operable communication with the power train and the lift cylinder pressure sensor. The controller is configured to receive the lift cylinder pressure signal; determine the rimpull limit based at least in part upon the lift cylinder pressure signal; and adjust the torque of the power train to the rimpull limit.

  • Publication number: 20190112790
    Abstract: A machine system and method are disclosed to generally prevent the tire slip of a machine conducting work. The machine system utilizes a controller in operable communication with a lift cylinder and lift cylinder pressure signal responsively producing a signal corresponding to a pressure within the lift cylinder. The controller utilizing the lift cylinder pressure signal to determine a rimpull limit for the machine and operably adjusting a torque of the machine to the rimpull limit proactively.
