  • Patent number: 9435104
    Abstract: A drive system for a mobile machine is disclosed. The drive system includes a power source configured to generate mechanical power, and a transmission driven by the power source, a traction device driven by the transmission. The drive system further includes a first input device configured to generate a signal to operate the machine, a second input device configured to receive an operator selection of one of a plurality of transmission modes, and a controller in communication with the first input device and the transmission. The controller is configured to adjust operation of the transmission to control a speed rate of change of the traction device in response to the signal from the first input device and based on the operator-selected one of the plurality of transmission modes.
    Type: Grant

  • Patent number: 8725366
    Abstract: A powertrain control system is disclosed. The powertrain control system may have a power source and a CVT coupled to an output of the power source. The powertrain control system may further have a controller in communication with the power source and the CVT. The controller may have a map with a plurality of speed modes, and, for at least one of the plurality of speed modes, the controller may be configured to vary an actual power source speed based on at least one of a CVT output speed or a ground speed.

  • Patent number: 8068969
    Abstract: A power distribution system is provided having a power source configured to generate a power output. The power distribution system also has an available power module configured to determine a total available power generated by the power source. In addition, the power distribution system has one or more parasitic power request modules configured to receive a request for power from an associated parasitic device and one or more non-parasitic power request modules configured to receive a request for power from an associated non-parasitic device. The power distribution system further has a power distribution module configured to cause the distribution of power among the parasitic and non-parasitic devices. The power distributed among the non-parasitic devices is the power remaining after the parasitic devices receive their requested power.
