  • Torque control arbitration in powertrain systems
    Patent number: 9050903
    Abstract: A method of regulating a torque output of a vehicle powertrain includes generating a plurality of torque requests and associating each of the plurality of torque requests with one of a plurality of arbitration domains to form torque request sets associated with each of the plurality of arbitration domains. A first torque request set is arbitrated within a first of the plurality of arbitration domains to provide a first torque request. The first torque request is introduced into a second torque request set associated with a second of the plurality of arbitration domains. The second torque request set is arbitrated within the second arbitration domain to provide a second torque request. A torque source is regulated based on the second torque request.
    Type: Grant

  • Use of torque model at virtual engine conditions
    Patent number: 9002550
    Abstract: A torque estimation system for a vehicle comprises an operating parameter module, a torque estimation module, and an estimation control module. The operating parameter module determines an estimated engine operating parameter based on engine speed. The torque estimation module estimates engine torque based on the engine speed and the estimated engine operating parameter. The estimation control module provides a plurality of engine speeds to the operating parameter module and the torque estimation module to determine estimated engine torque as a function of engine speed.
