Abstract
A vehicle powertrain includes an internal combustion engine having a crankshaft coupled to a flywheel having a ring gear. The powertrain also includes a transmission having an input shaft coupled to the flywheel and a brake mechanism having a pivotable rocker configured to selectively inhibit crankshaft rotation. The brake mechanism also includes an electric actuator configured to drive a plunger in connection with a first end of the rocker, wherein the first end engages the ring gear in a first position to inhibit forward rotation and a second end of the rocker engages the ring gear in a second position to inhibit rearward rotation.
