20090107455 | Engine Idle Speed and Turbocharger Speed Control - Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection. One example method includes performing at least a first and second injection during a cylinder cycle, the first injection generating a lean combustion and the second injection injected after combustion such that it exits the cylinder unburned into the exhaust upstream of a turbine of the turbocharger; and adjusting at least the first injection based on engine speed, where the at least first and second injection are performed responsive to turbocharger speed. | 04-30-2009 |
20090107456 | ENGINE IDLE SPEED AND TURBOCHARGER SPEED CONTROL - Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection. One example method includes performing at least a first and second injection in response to a driver action. The first and second injection may be performed during a cylinder cycle, the first injection generating a lean combustion and the second injection injected after combustion such that it exits the cylinder unburned into the exhaust upstream of a turbine of the turbocharger. | 04-30-2009 |
20100211298 | METHOD FOR STARTING A VEHICLE ENGINE - A method for starting a vehicle engine includes determining a throttle angle command output based on a throttle adjustment parameter. The throttle angle command output may be further adjusted based on a learned compensation adder and may be based on a number of vehicle engine starts. A throttle angle corresponding to the throttle angle command output is provided. | 08-19-2010 |
20100241323 | Enhanced Powertrain Performance During Knock Control - Various systems and methods are described for controlling combustion stability in an engine driving a transmission.

20140012475 | AUXILIARY VEHICLE CONTROL - A vehicle system includes a driver training vehicle and an auxiliary control unit that is removably installable in the vehicle. A vehicle control system can receive a brake input from a vehicle driver via a floor pedal in the vehicle as well as a brake input from a vehicle passenger via the auxiliary unit. The control system adjusts an engine torque and a brake torque based on the received brake inputs to decelerate the vehicle. | 01-09-2014 |
20140188370 | ENGINE IDLE SPEED AND TURBOCHARGER SPEED CONTROL - Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection.

20150051762 | METHODS AND SYSTEMS FOR TORQUE CONTROL - Methods and systems are provided for improving surge control. When surge conditions are approached, a reference governor reduces engine airflow at a slower rate and to a higher level than the engine airflow required to meet the reduced torque demand. The excess torque resulting from the extra airflow is offset by applying a negative torque on the driveshaft via an electric machine coupled to the engine or via alternate engine actuator adjustments. | 02-19-2015 |
20150353093 | DRIVER TRAINING INTERFACE - A driver training vehicle system includes a driver training vehicle and an interface system with an auxiliary control unit that is removably installable in the vehicle. A vehicle control system can receive a brake input from a vehicle driver via a floor pedal in the vehicle as well as a brake input from a vehicle passenger via the auxiliary unit. The control system adjusts an engine torque and a brake torque based on the received brake inputs to decelerate the vehicle. | 12-10-2015 |
