Methods and systems for an actuation system

A method for an actuation system, comprising:

• during a first condition, rotating a lever arm coupled to a motor via a parallel axis gear train in a first direction until an output gear of the parallel axis gear train is driven past a tangent point and is non-back drivable from a first state of the actuation system, and a locking pin coupled to a final parallel axis gear of the parallel axis gear train is in face sharing contact with the lever arm;
• and
• during a second condition, rotating the lever arm coupled to the motor via the parallel axis gear train in a second direction until the output gear is driven past the tangent point and is non-back drivable from a second state of the actuation system, and the locking pin is in face sharing contact with the lever arm, the second direction opposite to the first direction, wherein the lever arm is coupled to the output gear of the parallel axis gear train via a drive pin housed within a slot in the lever arm, and at the tangent point, a direction of travel of the drive pin is tangential to a longitudinal axis of the lever arm, and wherein the lever arm is further coupled to a pawl of a transmission system of a vehicle via a cam.

A method for a transmission system of a vehicle, comprising:

• rotating a parallel axis gear coupled to a lever arm through an eccentric drive pin housed in a slot of the lever arm, the drive pin fixed to the parallel axis gear to rotate the lever arm and the lever arm not directly attached to the parallel axis gear;
• and
• engaging and disengaging a pawl of the transmission system by the rotation of the lever arm between two fixed end positions, wherein the lever arm rotates through an angle substantially smaller than an angle of rotation of the parallel axis gear, and wherein at the two fixed end positions, a locking pin coupled to a final parallel axis gear of the parallel axis gear is in face sharing contact with the lever arm.
