Controlling a clutch by means of an actuator, wherein at least one first shaft can be torque-transmittingly connected to a second shaft by means of the clutch, the clutch in one of at least three states, where in an disengaged first state, a torque cannot be transmitted, in a second state, a torque can be transmitted such that the speeds of the first shaft and the second shaft are synchronized in the second state, and in an engaged third state, a required torque can be transmitted; wherein, in various states and in an operating mode associated with the particular state, the actuator is adjusted at a different speed in order to adjust the clutch.

Controlling a clutch by an actuator

A method for controlling an actuator of an actuator unit of a motor vehicle includes detecting desired activation of the actuator, detecting whether a currently present operating state of the motor vehicle is a first operating state or a second operating state, selecting either a first control routine upon detecting the first operating state or a second control routine upon detecting the second operating state, and actuating the drive motor with the selected first control routine or second control routine. A drive motor of the actuator unit is controlled depending on the operating state of the motor vehicle. In the first operating state, an actuation of the actuator occurs according to the first control routine with high dynamics of the drive motor, and in the second operating state, the actuation of the actuator occurs according to the second control routine with adjusted dynamics of the drive motor.

Controlling an actuator of an actuator unit of a motor vehicle

Operating a drive train of a vehicle having a clutch assembly, wherein the clutch assembly is actuatable via an actuating device for the switchable transmission of a torque, wherein a first state of the actuating device, and thus a second state of the clutch assembly, is settable via a position of a drive unit of the actuating device, comprises:
