    摘要： A method to start operation of an internal combustion engine of a hybrid powertrain includes initiating rotation of a crankshaft of the engine with at least one electric machine in accordance with a first ramping profile until a first predetermined speed is achieved in response to an engine start event during a cold start condition. Engine speed is monitored and the engine is fired while controlling the engine speed to maintain the first predetermined speed with the at least one electric machine. The first ramping profile is adjusted at a rate corresponding to an estimated rate at which the engine speed is increasing during the engine firing. When at least one predetermined combustion quality parameter is achieved, the engine speed is controlled in accordance with a second ramping profile until a second predetermined speed is achieved based on controlling combustion parameters of the engine.

    摘要： A method for starting an internal combustion engine in a hybrid powertrain having an electric torque machine mechanically coupled to the internal combustion engine includes monitoring a temperature state of the hybrid powertrain, determining a maximum discharging power limit of the high-voltage battery corresponding to the temperature state of the hybrid powertrain, estimating an engine drag torque associated with the temperature state of the hybrid powertrain, selecting a preferred engine cranking speed associated with the estimated engine drag torque and achievable at less than the maximum discharging power limit of the high-voltage battery, and controlling the electric torque machine to generate a magnitude of motor torque output sufficient to crank the internal combustion engine at the preferred engine cranking speed.
