SYSTEM AND METHOD FOR CONTROLLING AN ENGINE BASED ON A DESIRED TURBINE POWER TO ACCOUNT FOR LOSSES IN A TORQUE CONVERTER

摘要

A system according to the principles of the present disclosure includes a desired turbine power module and an engine actuator module. The desired turbine power module determines a desired amount of power at a turbine of a torque converter based on an accelerator pedal position and a vehicle speed. The torque converter transfers torque from an engine to a driveline and includes an impeller and the turbine. The impeller is connected to a crankshaft of the engine. The turbine is connected to a transmission in the driveline and is at least one of hydraulically coupled and mechanically coupled to the impeller. The engine actuator module controls an actuator of the engine based on the desired turbine power.
