Sensor signal evaluating method for positioning adjusting element e.g. window lifter of motor vehicle, involves receiving value when difference between sensor signal and out-of-phase analog signal falls below threshold value

摘要

The method involves producing an out-of-phase analog signal (SPT, SP) by a phase shift of an analog sensor signal (SH). A digital evaluation signal (SST) is produced by comparing the analog sensor signal and the out-of-phase analog signal. A value is received when the difference between the sensor signal and the out-of-phase analog signal exceeds a threshold value. Another value is received when the difference between the sensor signal and the out-of-phase analog signal falls below another threshold value. An independent claim is also included for a device for producing and evaluating a sensor signal a magnetic field suspended sensor.
