  • Methods and systems for power take off device torque delivery
    Patent number: 10570849
    Abstract: Methods and systems are provided for controlling a vehicle engine to deliver desired torque to a power take off device coupled to the engine. In one example, the method may include, learning a filtered PTO torque demand during vehicle acceleration, and steady state operation, and during transition in engine states using the learned PTO torque demand to adjust engine speed in order to deliver a desired engine torque output for optimal operation of the PTO device.
    Type: Grant
    Filed: February 26, 2018
    Date of Patent: February 25, 2020
    Assignee: Ford Global Technologies, LLC
    Inventors: Dennis E. Homant, Bradley Dean Riedle, David James Liller
