  • 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.
    Type: Grant

  • Patent number: 7346447
    Abstract: An engine knock control system for an engine having a turbocharger includes a first module that determines octane scalars indicative of an engine knock propensity for each cylinder of the engine system and a second module that determines a cylinder air mass limit based on the octane scalars. A third module limits a boost output of the turbocharger based on the cylinder air mass limit.
