Claim 6:
7. The control unit (8) as claimed in claim 6,
wherein the control unit (8) for determining (300) the contact position (K) on the basis of the rotor position (φ) is configured
to define (302) a maximum current (imax) for the drive motor (A),
to operate (304) the drive motor (A) with a motor current (i) which is less than or equal to the maximum current (imax),
to determine (306) a rotor end position (φmax) of the drive motor (A) for which no further change in the rotor position (φ) of the electromechanical brake actuator (2) occurs for the given maximum current (imax),
to determine a contact position (K) from the rotor end position (φmax), in particular on the basis of first correlation parameters (K1).
