The invention relates to a driveshaft lock (10) and to a method (50) of retrofitting the driveshaft lock to a vehicle. The driveshaft lock (10) includes a rotor (17) which defines a star-shaped central aperture (20) which is configured to receive a non-circular, peripheral profile of a drive flange (13) therethrough such that the rotor (17) is configured to piggyback on the drive flange (13). The lock (10) includes a locking member (21) which is configured selectively to engage the rotor (17) in order to lock the rotor in position and prevent angular displacement thereof. Amongst other steps, the method (50) includes aligning the aperture (20) of the rotor with the profile of the drive flange, passing the rotor over the drive flange, rotating the rotor relative to the drive flange, and securing the rotor to the drive flange for rotation together with the drive flange, piggyback-style.

A shift range control device includes an angle detector, a valley position learner, and a validity determiner. The angle detector detects a rotation angle of an output shaft of a shift actuator. The valley position learner learns the rotation angle of the output shaft when a locker is positioned at a valley bottom of a recess as a valley position based on a detection angle of the angle detector. The validity determiner determines validity of a learning value of the valley position learner.

An actuator assembly that includes a frame, an output member, a latch and a spring. The output member is movable along an axis relative to the frame between a first position and a second position. The latch has a first latch member, which is movable along the axis, and a second latch member that is coupled to the output member. The second latch member is configured to engage the first latch member to retain the actuator output member in the first position. The spring exerts a force on the actuator output member when the second latch member engages the first latch member to retain the actuator output member in the first position. The force is configured to urge the actuator output member toward the second position when the second latch member is disengaged from the first latch member.

A rotary actuator is used in a shift-by-wire system for a vehicle. The rotary actuator includes a motor, a controller, a housing, and a biasing member. The controller controls the motor. The housing supports a rotor assembly of the motor and holds the controller. The biasing member biases the rotor assembly in an axial direction to eliminate a thrust movement gap between the rotor assembly and the housing.

The disclosure relates to an actuator arrangement for operating a clutch and a parking lock in a driveline of a motor vehicle, comprising: a clutch having a clutch actuating member configured to drivingly connect or disconnect a clutch input part and a clutch output part; a parking lock having a locking element movable to a locking position to lock a ratchet wheel, and to a release position to release the ratchet wheel; and a parking lock actuating member for actuating the locking element; a controllable actuator with a movable actuator setting member which is movable into at least three setting positions and is operatively connected to the clutch actuating member and to the parking lock actuating member such that in a first setting position the parking lock is closed, in a second setting position the clutch is closed, and in a third setting position the clutch and the parking lock are opened.

A rotary actuator is used in a shift-by-wire system for a vehicle. A speed reducer includes a ring gear and a sun gear and reduces a rotational speed of the motor. An output shaft outputs rotation of the motor at a reduced rotational speed by the speed reducer. A regulating pin is disposed in a fixing member and allows the sun gear to revolve around a rotational axis of the motor and to rotate about an eccentric axis. The regulating pin is a separate member from the fixing member. The regulating pin has a strength equal to or greater than a maximum torque reaction force received from the sun gear. A first difference in hardness between an engaging portion and the sun gear is set to be less than a second difference in hardness between the fixing member and the sun gear.
