A hybrid diesel-electric powertrain includes an electric motor in electrical communication with a traction battery, a diesel engine in power-flow communication with the electric motor and with an automatic transmission, and a controller. The diesel engine and electric motor are configured to provide a combined torque to the automatic transmission. The powertrain further includes an exhaust aftertreatment device in fluid communication with the diesel engine. The controller is configured to: receive a regeneration request from the exhaust aftertreatment device; determine if a state-of-charge of the fraction battery is within a predetermined range of a target value; initiate a regeneration event if the state-of-charge of the traction battery is within the predetermined range of the target value; receive an immediate torque request from the automatic transmission; and provide a torque command to the electric motor in response to the immediate torque request.
