Abstract: A system and method for controlling an internal combustion engine control an actuator in response to variations of intake airflow relative to an average intake airflow to manage induction acoustics. The system and method may include controlling an actuator, such as a throttle valve, to increase intake manifold vacuum in response to intake airflow. In an engine having electronically actuated intake and/or exhaust valves, intake airflow is estimated based on at least engine speed and valve timing and compared to a measured intake airflow to determine a first difference. The measured airflow is divided into a steady-state and transient term or component with a second difference determined based on the transient component and a target value. Throttle valve position is selectively controlled to increase vacuum in response to a combination of the first and second difference to manage induction acoustics.

Abstract: A method for controlling stopping and starting of an engine having a variable event valvetrain is described. According to the method engine valves may be used to reduce engine evaporative emissions as well as engine starting emissions.

Abstract: A system and method for controlling an internal combustion engine in a vehicle include controlling the engine to achieve a desired vehicle speed/deceleration when the accelerator pedal is released. A desired vehicle deceleration may be determined based on current transmission gear, vehicle speed, and road grade. Vehicle speed/deceleration is measured using a vehicle speed sensor and/or wheel speed sensor(s) and the engine is controlled to reduce the error between the desired and measured decelerations. Electronically actuated intake and/or exhaust valves, and/or an electronically controlled throttle may be used to achieve a desired vehicle deceleration profile. A selector switch or similar device may be used by the driver to select a desired deceleration profile from two or more available profiles and/or a desired deceleration profile may be automatically selected based on current ambient and/or vehicle/engine operating conditions.

Abstract: A method for controlling an engine to reduce vehicle shuffle mode vibration during mode transition. The engine includes multiple cylinders, each with at least one electrically actuated valve, and the engine operates in a first mode having a first number of firing cylinders and a second mode having a second number of firing cylinders. The method comprises transitioning the engine from operating in the first mode to the second mode; adjusting at least a valve timing or lift of one of a last cylinder to be fired in said first mode and a first cylinder to be fired in said second mode to temporarily adjust a cylinder torque and thereby reduce vehicle shuffle mode vibration.
