Abstract
In a parallel hybrid vehicle having and internal combustion engine and an electric motor operatively connected to a transmission shaft, a multimode mechanical clutch selectively couples an output shaft of the internal combustion engine to the transmission shaft. The multimode clutch has a two-way unlocked mode where the output shaft and transmission shaft can rotate independently in either direction, and a one-way locked, one-way unlocked mode where the shafts are locked to rotate together in one direction and unlocked for independent rotation in the opposite direction. The clutch may also have a two-way locked mode where the shafts rotate together in both directions. Pawls may be provided to engage and disengage as needed to execute the modes of the multimode clutch actuator.
