Abstract
A selectively actuatable one-way clutch is controlled to brake or release a generator such that a powersplit hybrid powertrain enters or exits a parallel mode of operation. To brake the generator and enter the parallel mode, the clutch is activated while overrunning the generator before the generator is slowed to engage the clutch. To release the generator and exit the parallel mode, the generator is controlled to overrun the clutch before deactivating the clutch and returning the generator to a base speed control.
