A method of operating a hybrid powertrain having an internal combustion engine monitors a throttle intake pressure and calculates a first torque capacity from a pressure model using the throttle intake pressure as an input. The method determines a maximum expected air mass from the monitored throttl ...

Jeffrey M Kaiser, Christopher E Whitney, Timothy W Athan, Dennis A Light, Timothy L Gibbs: Torque limiting engine lubrication protection system. December 10, 2013: US08602001

A lubrication torque limit module includes a temperature module that determines a temperature of an engine and generates an engine temperature signal. A limit module generates a torque limit signal based on the temperature signal and a speed of the engine. The torque limit signal identifies an indic ...
