Claim 10:
11. A lock module assembly for controlling bidirectional rotations of a wheel hub of a vehicle having a vehicle frame and a rotating shaft to rotate the wheel hub, said lock module assembly comprising:
a disconnect race fixedly secured to the rotating shaft, said disconnect race extending out to a disconnect periphery;
at least one disconnect locking element housed within said disconnect race;
a control race having at least one disconnect tooth selectively engageable with said at least one locking element of said disconnect race, wherein said control race rotates with said disconnect race when said at least one disconnect locking element engages said at least one disconnect tooth, said control race having at least one control tooth in spaced relation to said at least one disconnect tooth;
a disconnect actuator for operatively engaging said at least one locking element to selectively connect and disconnect said control race to and from said disconnect race;
at least one clockwise control actuator for operatively engaging said at least one control tooth on said control race preventing movement of said control race in a counter-clockwise direction; and
at least one counterclockwise control actuator for operatively engaging said at least one control tooth on said control race preventing movement of said control race in a clockwise direction;
wherein said at least one disconnect actuator operatively disconnects the wheel hub from the rotating shaft to affect a neutral state for the wheel, and said at least one clockwise and said at least one counterclockwise control actuators affect a hill hold state in one of the bidirectional rotations, a hill hold state in the other of the bidirectional rotations, and a park state preventing the wheel from rotating in either of the bidirectional rotations.
