Controlling an actuator of an actuator unit of a motor vehicle

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.

Disclosed are dry clutch control method and apparatus for a vehicle. The method may include a reference speed generating step of generating a virtual target input shaft speed from a wheel speed, a vibration recognizing step of detecting a vibration component based on a difference between an actually measured input shaft speed and the virtual target input shaft speed, and a control input step of additionally applying an anti judder control input to a clutch control torque controlling a dry clutch connected to an input shaft. The anti judder control input may be applied to the vibration component recognized in the vibration recognizing step in a form of being continuously damped starting from an impulsive control input.
