摘要： A system for use with a direct current fast-charging (DCFC) station includes a controller and battery system. The battery system includes first and second battery packs, and first, second, and third switches. The switches have ON/OFF conductive states commanded by the controller to connect the battery packs in a parallel-connected (P-connected) or series-connected (S-connected) configuration. An electric powertrain with one or more electric machines is powered via the battery system. First and second charge ports of the system are connectable to the station via a corresponding charging cable. The first charge port receives a low or high charging voltage from the station. The second charge port receives a low charging voltage. When the station can supply the high charging voltage to the first charge port, the controller establishes the S-connected configuration via the switches, and thereafter charges the battery system solely via the first charge port.

摘要： Presented are model-based control systems for operating parallel hybrid powertrains, methods for making/using such systems, and motor vehicles with parallel hybrid powertrains and model-based torque and speed control capabilities. A method for controlling operation of a hybrid powertrain includes receiving a command signal for a hybrid powertrain operation associated with a driver input and a current operating mode of the powertrain. A desired output torque for executing the powertrain operation is then determined. The method determines if a speed differential between an engine speed of an engine and a torque converter output speed of a torque converter is less than a calibrated threshold; if so, the method responsively engages a clutch device to operatively connect the engine's output member to the transmission's input member. Engine torque is then coordinated with motor torque such that the sum of the engine and motor torques is approximately equal to the desired output torque.

摘要： An internal combustion engine has a cylinder configured to combust an air-fuel mixture and expel an exhaust gas and a turbocharger for generating a pressurized airflow to the cylinder. The turbocharger includes a turbine scroll defining an inlet and an outlet, an exhaust gas driven rotating assembly having a turbine wheel disposed inside the turbine scroll, and a waste-gate defining an opening. A first sensor detects turbine outlet pressure. A second sensor detects turbine inlet temperature. A controller determines an effective area of the waste-gate opening and an exhaust gas mass flow-rate. The controller also determines a turbine inlet pressure in response to the detected turbine outlet pressure and the turbine inlet temperature, and the determined waste-gate opening effective area and the exhaust gas mass flow-rate. The controller additionally regulates a supply of fuel to the cylinder corresponding to the pressurized airflow affected by the determined turbine inlet pressure.

摘要： An engine includes an exhaust gas recirculation system with a high pressure exhaust gas recirculation loop and a low pressure exhaust gas recirculation loop, and an air charging system. A method of controlling the air charging system includes monitoring an actual exhaust gas recirculation rate, operating conditions of a compressor and turbine in the air charging system. A compressor flow is determined based on a target exhaust gas recirculation rate, a target intake manifold pressure and the actual exhaust gas recirculation rate. A power requested by the compressor is determined based on the compressor flow, the target intake manifold pressure, and the monitored operating conditions of the compressor. A power to be generated by the turbine is determined based upon the power requested by the compressor. A turbine flow is determined based upon the power to be generated by the turbine and the monitored operating conditions of the turbine. A system control command is determined based on the turbine flow and the monitored operating conditions of the turbine. The air charging system is controlled based on the system control command.

摘要： A method is disclosed for controlling a two-stage turbocharger system having low-pressure and high-pressure turbochargers in line, sequentially, with an engine. The turbochargers include a low-pressure (LP) turbine and an LP compressor, and a high-pressure (HP) turbine and an HP compressor. The LP compressor feeds the HP compressor, which feeds the engine intake. The engine exhaust feeds the HP turbine, which feeds the LP turbine. The method determines a total boost pressure, which provides combustion reactant for the engine. The method calculates an LP compressor power from the determined total boost pressure, and an LP turbine flow from the LP compressor power. The low-pressure turbocharger operates at the calculated LP turbine flow. The method calculates an HP compressor power from the determined total boost pressure, and an HP turbine flow from the HP compressor power. The high-pressure turbocharger operates at the calculated HP turbine flow.
