Abstract: Methods and systems are provided for accounting for a difference between an expected amount of fuel scheduled to be delivered and an actual amount of fuel delivered to an engine cylinder during a fueling event. In one example, a method may include scheduling a direct injection to a cylinder based on an estimated expected amount of fuel injected to the cylinder during an immediately previous injection event. The expected amount of fuel injected during the immediately previous injection event may be a function of an average fuel rail pressure during the immediately previous injection event.

Abstract: Methods and systems are provided for reducing errors in estimated fuel rail pressure incurred at the time of a scheduled injection event due to engine-driven cyclic fuel rail pressure changes. In one example, a pulse-width commanded during a scheduled injection event is determined as a function fuel rail pressure samples collected over a moving window that is customized for the corresponding fuel injector. In another example, the commanded pulse-width is determined as a function of an average fuel rail pressure sampled during a quiet zone of injector operation and predicted fuel rail pressure altering events occurring between the quiet zone and the scheduled injection event.

Abstract: Methods and systems are provided for improving engine restart operations occurring during a transmission shift in a hybrid vehicle. Engine speed is controller during cranking and run-up to approach a transmission input shaft speed that is based on the future gear of the transmission shift. Engine speed is controlled via adjustments to spark, throttle, and/or fuel, to expedite engine speed reaching the synchronous speed.

Abstract: A method and system for improving starting of an engine is presented. In one example, the method selects a first cylinder to receive fuel since engine stop the cylinder's position relative to the cylinder's top-dead-center compression stroke. The method also describes adjusting a number of fuel injections for a first combustion event since engine stop.

Abstract: A method for controlling a hybrid vehicle powertrain, where the powertrain includes a motor and an engine, includes providing a first motor torque in response to an engine start request. The first motor torque cranks the engine through a first compression event. The method additionally includes providing a second motor torque in response to the engine being cranked through the first compression event. The second motor torque is less than the first motor torque.
