Abstract: A system includes a power transmission mechanism having a rotation shaft, a power transmission gear, a dog ring, a dog clutch, a switching mechanism to move the dog ring in an axial direction to switch a power transmission state, and a switching controller to control an operation of the switching mechanism. The switching controller determines whether the dog clutch is in an engaged state when giving a switching command to cause the dog ring to be moved to a side of the power transmission gear in the axial direction. After the dog clutch is determined not to be in the engaged state, the switching controller causes the dog ring to be moved to the side opposite to the power transmission gear, and then retries movement of the dog ring to the side of the power transmission gear.

Abstract: The present teachings generally provide for an actuator assembly to move between a decoupled position, and a coupled position. The actuator assembly includes a shift assembly including a gear connected to the motor, an input member in communication with the gear configured to transition between a first position and a second position; an output member operatively connected to the input member and configured to move a distance defining a stroke length between a disengaged position and an engaged position; and a biasing member connecting the input member to the output member. The input member rotates from the first position to the second position relative to the output member, increasing a tension of the biasing member due to an interference causing a blocked condition. The biasing member rotates the output member in a releasing condition upon clearance of the interference such that the output member rotates through the stroke length.
