Abstract
Techniques for synchronizing shaft speeds of a hybrid powertrain of a hybrid vehicle include, during a first phase of a synchronization process, starting an engine using a first electric motor and increasing a speed of an output shaft of the engine to a first speed that is less than a second speed of an intermediate powertrain shaft on an opposing side of a disconnect clutch relative to the engine output shaft, and during a subsequent second phase of the synchronization process, performing a model-based determination of a target speed profile for the engine to follow from the first speed to the second speed and controlling the engine to increase its speed according to the target speed profile, and closing the disconnect clutch when the speeds of the engine output shaft and the intermediate powertrain shaft are synchronized.
