Patent ID: 11398765

Abstract:
A method is for calibrating a multiturn sensor for determining the position of a spindle of a clutch actuator, in which the multiturn sensor (5) is operatively connected to a magnetic field of a permanent magnet (12) in that the multiturn sensor (5) is combined with an actuator transmission (3) which comprises a spindle (9) bearing the permanent magnet (12). In a calibration method which can be carried out particularly quickly and cost-effectively, during the assembly of the multiturn sensor (5), arranged on a carrier element (4), with the actuator transmission (3) bearing the spindle (9), the multiturn sensor (5) is operated outside its specified rotational range (0, n), wherein a position, set by actuating the actuator transmission (3), of the spindle (9) bearing the permanent magnet (12) provided for an operating case of the clutch actuator (1), is assigned to a specified end position of the rotational range (0, n) of the multiturn sensor (5), as a result of which a magnetic field of the permanent magnet (12) is aligned with the multiturn sensor (5).
