A shock caused due to a change in the direction of torque transferred to an output shaft is reduced. There is provided a control device for a powertrain including a drive power source that transfers torque to an output shaft connected to a wheel of a vehicle, and a rotary electric machine that transfers torque to the output shaft via a transmission. When electric power generation performed using the rotary electric machine is restricted, if torque that decelerates the vehicle is transferred from the drive power source to the output shaft, a control is executed so that torque that does not decelerate the vehicle is transferred from the drive power source to the output shaft, and a shift control over the transmission is executed.

The invention relates to a drive assembly for a closure element (2) of a motor vehicle (3). A clutch assembly (11) is provided which is connected into the powertrain (4) of the drive assembly (1) andwhich comprises a drive connection (12a) and an output connection (12b). In any case, a movement which is introduced on the drive side is guided through the clutch assembly (11) to the output connection (12b), and the clutch assembly (11) has a brake assembly (13) with a main brake element (15) which generates a main brake action, by means of which the main brake element (15) brakes a movement introduced on the output side. The clutch assembly (11) has a freewheel assembly (16), wherein the freewheel assembly (16) engages the main brake element (15) by means of the movement introduced on the output side and disengages the main brake element (15) by means of a movement introduced on the drive side. According to the invention, the brake assembly (13) has an additional auxiliary brake element(17) which generates a specified permanent brake action, by means of which the auxiliary brake element (17) acts at least against the movement introduced on the output side, and the specified permanent brake action of the auxiliary brake element (17) must be overcome so that the freewheel assembly (16) can be disengaged.

The invention relates to a multi-disc clutch (1) for a hybrid module (2) of a motor vehicle drivetrain (3), having a first clutch component (4a) and a second clutch component (4b) which can be coupled as desired to the first clutch component (4a) for conjoint rotation, wherein the first clutch component (4a) has a first carrier (7) which is provided for connection to a rotor (5) of an electric machine (6) for conjoint rotation and has a first group (8) of frictional elements (9a, 9b, 9c) which is connected to the first carrier (7) for conjoint rotation, and the second clutch component (4b) has a second carrier (10) and a second group (11) of frictional elements (12a, 12b) which is coupled to the second carrier (10) for conjoint rotation, wherein the frictional elements (9a, 9b, 9c) of the first group (8) are arranged in alternation with the frictional elements (12a, 12b) of the second group (11) next to one another in an axial direction of a common rotational axis (13), wherein a first frictional element (9a) of the first group (8), which first frictional element is connected in an axially fixed manner to the first carrier (7), is connected to a second frictional element (9b) of the first group (8) for conjoint rotation via a driver element (14) which is held for conjoint rotation and in an axially relatively displaceable manner on the first frictional element (9a) of the first group (8). The invention also relates to a hybrid module (2) and a dual clutch device (30), each designed with a multi-disc clutch (1). The invention also relates to a drivetrain (3).
