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： An engine control system comprises a base air per cylinder (APC) module, a catalyst temperature adjustment module, an ambient temperature adjustment module, and an APC adjustment module. The base APC module determines a base APC to reduce first engine pumping losses during a first deceleration fuel cutoff (DFCO) event relative to second engine pumping losses during a second DFCO event. The catalyst temperature adjustment module determines a catalyst temperature adjustment based on a catalyst temperature during the first DFCO event. The ambient temperature adjustment module determines an ambient temperature adjustment based on an ambient air temperature during the first DFCO event. The APC adjustment module selectively adjusts the base APC based on the catalyst temperature adjustment and the ambient temperature adjustment and controls at least one of the engine airflow actuators based on the adjusted base APC during the first DFCO event.

摘要： A vehicle includes an engine, a controller for turning off the engine when the vehicle is idle, a motor/generator for starting the engine, an inverter for converting a DC auxiliary voltage from a battery into an AC voltage for powering the motor/generator, and a device for isolating a DC voltage from the DC auxiliary voltage to prevent voltage sag in a vehicle system during engine starting. The device includes a transformer, a rectifier/regulator, and an isolator. A mechanical relay opens, or an FET is activated, to isolate the DC voltage during engine start. A method for preventing voltage sag in an auxiliary vehicle system includes detecting a commanded engine start, comparing a measured auxiliary voltage to a threshold, isolating a predetermined DC voltage from a DC auxiliary voltage when the measured auxiliary voltage is less than the threshold, and powering the auxiliary vehicle system using the isolated DC voltage.
