Abstract
Methods and systems are provided for improving engine restart operations in a hybrid vehicle. While an engine is cranked via motor torque, engine fueling is delayed until the engine speed is sufficiently high and the engine has been rotating in a forward direction continuously for a threshold duration. A disconnect clutch between the engine and motor is slipped while the engine cranks, the clutch engaged only after the engine has run up to the motor speed.
