Abstract: A system according to the principles of the present disclosure includes an exhaust braking enabling module, a driver torque module, and an engine actuator control module. The exhaust braking enabling module selectively enables exhaust braking based on driver input and independent of an accelerator pedal position. The driver torque module selectively determines a driver torque request based on a powertrain braking torque capacity when exhaust braking is enabled. The engine actuator control module controls fuel delivery to cylinders of an engine and a vane position of a turbocharger based on the driver torque request.

Abstract: A method for selecting an engine operating point in a multi-mode powertrain system includes monitoring a desired axle torque based on an operator torque request and vehicle speed. For each available combustion mode of the diesel engine, engine torque and speed ranges are received and a plurality of fuel losses and a plurality of emissions losses are retrieved, each fuel and emissions loss corresponding to respective ones of a plurality of engine operating points within the engine torque and speed ranges. The respective fuel and emissions losses are compared at each of a plurality of potential engine operating points within the engine torque and speed ranges of the available combustion modes. A desired engine operating point within one of the available combustion modes is selected that corresponds to one of the potential engine operating points having a lowest power loss based on the compared respective fuel and emissions losses.
