    Abstract: Presented are hybrid electric vehicle (HEV) powertrains and control logic for vehicle response management, methods for making/operating HEV powertrains, and motor vehicles equipped with HEV powertrains. A method of controlling a hybrid powertrain includes receiving data indicative of a motor speed of a traction motor and torque commands for the motor, an engine, and an engine disconnect clutch (EDC). A vehicle controller uses a state observer module to estimate a jerk response based on the motor speed, and determines if the EDC is in a torque-transmitting active state. Responsive to the EDC being in the active state, the controller calculates an incremental feedback control signal that is predicted to reduce the estimated jerk based on the engine, motor, and clutch torque commands. One or more torque command signals are transmitted to the engine, motor and/or EDC to modulate a torque output thereof based on the incremental feedback control signal.

    Abstract: A method, system, and engine are configured to determine a parameter based on rotational speeds of a crankshaft, over at least three cylinder combustion cycles. The method, system, and engine determine two or more estimated crankshaft rotational speeds at two or more positions in a leading cylinder combustion cycle, two or more estimated crankshaft rotational speeds at two or more positions in a middle cylinder combustion cycle, and two or more estimated crankshaft rotational speeds at two or more positions in a following cylinder combustion cycle. The method, system, and engine are configured to determine a calculated metric based on each of the determined leading estimated crankshaft rotational speeds, the determined middle estimated crankshaft rotational speeds, and the determined following estimated crankshaft rotational speeds. An engine parameter, such as misfire, is then determined based on the calculated metric.
