Abstract
Official abstract text for this publication.
A method for slip regulation of a friction clutch by a clutch actuator operated by an electronically commutated electric motor. Here, rotational motion of a rotor is converted into an axial advancement that sets a predetermined slip. The rotational motion is controlled by Hall sensors arranged over a circumference around a rotational axis of the rotor. Magnetizable magnet segments, which are offset from each other in the circumferential direction, communicate depending on continuously detected signals of the Hall sensors. To perform the slip regulation even for axial travels of the clutch actuator that correspond to an angular position of the rotor between two Hall sensors, the signals of the Hall sensors over the circumference are evaluated in an analog manner, and an angular position of the rotor between two sensors is determined by comparing two signals adjacent to each other in the circumferential direction with each other.
First claim
Opening claim text (preview).
What is claimed: 1. A method for slip regulation of a friction clutch of a clutch actuator operated by an electronically commutated electric motor, the method comprising the steps of: converting in the clutch actuator a rotational movement of a rotor of the electric motor into axial travel which sets a predetermined slip; controlling the rotational movement by a plurality of Hall sensors, which are arranged over a circumference around a rotational axis of the rotor; commutatin…
