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.
