Disclosed herein is a dual clutch actuator including: a housing; a stroke controller disposed in the housing, and configured to actuate a clutch by linearly moving a pushrod; a power generation unit configured to generate driving power to operate the stroke controller; and a stroke return unit disposed between the housing and the stroke controller so as to elastically support the stroke controller, and configured to return the linearly moved pushrod to the original position, when the operation of the clutch is released. According to this structure, the dual clutch actuator can return the pushrod to the original position without an operation of a separate actuator, when removing a clutch connection.

An electric lock includes a cover, a clutch rod, a driving module, a clutch member and a handle. The clutch rod is movably connected to a latch. The driving module is disposed on the cover. The driving module includes a driving member abutting against and rotatable relative to the cover, and a motor configured to drive the driving member to rotate. The handle is connected to the clutch member. Wherein, when the motor drives the driving member to rotate relative to the cover along a first rotating direction, the driving member drives the clutch rod to move toward the handle to be engaged with the clutch member for allowing the handle to drive the latch to move through the clutch rod when the handle is rotated.

A system and method for controlling a powertrain, comprising an internal combustion engine connected to a double clutch transmission having a first and a second partial transmission with at least one shiftable transmission stage. A first friction clutch is arranged between the internal combustion engine and the first partial transmission, and a second friction clutch is arranged between the internal combustion engine and the second partial transmission. An engine torque of the internal combustion engine is transmitted by the first and second friction clutches to the first or second partial transmissions to provide a drivetrain torque at the output of the double clutch transmission. The powertrain is monitored for an occurrence of juddering oscillations, wherein in response to juddering oscillations being detected a regeneration process of one of the first and second friction clutches is triggered, and a friction lining is removed in the regeneration process.

A vibration reduction apparatus of a hybrid vehicle includes a differential rotation detector configured to detect a difference between a rotational speed of an output shaft of a prime mover and a rotational speed of a second rotating shaft, and controller configured to control a driving part and an electric motor so as to switch an operation mode from a first mode where a torque of the prime mover is output to an electric motor and a third shaft to a second mode where torque of the prime mover and the electric motor is output to the third shaft, when the difference detected by the differential rotation detector in the first mode is within a predetermined range continuously for a predetermined time.
