Abstract
The present invention is directed to a method for determining a force transmission contact point of an actuating element () of an electric clutch actuator which comprises a linear drive assembly configured to linearly move the actuating element () towards a preload plunger () which is linked by a pushrod () to a clutch lever () and to move the pushrod () to turn the clutch lever, characterized by including the steps: monitoring an oscillation of the pushrod () by monitoring the position of the pushrod () and determining in consecutive time periods at least one of a maximum, minimum and centre value of the pushrod position, deriving a measure of non-oscillatory movement of the pushrod () based on a difference between at least one of the respective maximum, minimum and centre values of the pushrod position in a current and at least one of the preceding time periods or based on a difference between a combination of the respective positions in the current and at least one of the preceding time periods; and determining that the actuating element () has reached the force transmission contact point if the measure of non-oscillatory movement of the pushrod exceeds a predetermined threshold value.
