Method for determining position of e.g. window lifter of motor car, involves acquiring magnetic field alterations generated by displacement of window lifter during active cycle of Hall sensor in current saving mode
Method for determining position of e.g. window lifter of motor car, involves acquiring magnetic field alterations generated by displacement of window lifter during active cycle of Hall sensor in current saving mode
The method involves setting a Hall sensor (7) which is connected with a window lifter (1), in current saving mode. The magnetic field alterations generated by displacement of the window lifter are acquired during active cycle of the Hall sensor. The Hall sensor is switched to permanent active mode on receiving a control signal for continuous acquisition of magnetic field alterations generated by displacement of the window lifter. The Hall sensor is switched again to the current saving mode, when control signal is not received for preset time. An independent claim is included for device for determining position of electromotor-driven servo unit.
