Abstract
A hybrid diesel-electric powertrain includes a diesel engine in power flow communication with an electric motor and a controller. The diesel engine and electric motor are each configured to generate a respective torque in response to a provided torque command. The controller is in communication with the electric motor, the diesel engine, and an accelerator pedal, and configured to receive a driver torque request from the accelerator pedal. In response to the driver torque request, the controller is further configured to command the diesel engine to generate an output torque that is less than a smoke limit torque, and command the electric motor to generate an output torque equal to the difference between the driver torque request and the output torque of the diesel engine.
