    摘要： A method and article of manufacture are provided for operating an internal combustion engine adapted to transmit torque to a hybrid transmission. The method comprises determining engine input torque transmittable to the hybrid transmission for each of a plurality of engine states. Costs are determined for operating the engine and hybrid transmission in the engine states to substantially meet an operator torque request. A preferred engine state is selected based upon the determined costs. The engine is controlled based upon the preferred engine state to substantially meet an operator torque request.

    摘要： 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.

    摘要： A method to control an output torque of a powertrain in response to an incipient transient speed event within the powertrain includes determining an incipient transient speed event, determining a maximum output torque capability profile based upon the incipient transient speed event, determining a minimum value of the maximum output torque capability profile, and limiting the output torque to not greater than the minimum value of the maximum output torque capability profile until the incipient transient speed event is concluded.

    摘要： A multi-mode vehicular powertrain system includes an internal combustion engine fluidly coupled to an exhaust aftertreatment system including a catalytic device and an electric machine electrically coupled to a battery. A method for effecting light-off of the catalytic device includes monitoring an output torque request for the powertrain system and determining a preferred engine operating point having a minimum engine operating cost within a predetermined engine operating region for catalyst light-off. When a state-of-charge of the battery is not approaching a predetermined state-of-charge limit, operation of the engine is controlled to the preferred engine operating point and operation of the electric machine is controlled to a machine operating point wherein the combination of engine torque at the preferred engine operating point and electric machine torque at the machine operating point satisfies the output torque request.
