Abstract
High resolution and accuracy of the measured values for detection of the position, speed and/or acceleration of a drive is ensured. The tolerances are determined and considered in signal evaluation on a partitioned basis. Measurement errors caused by inaccuracies of the signal generator due to manufacturing difficulties are greatly reduced or eliminated such that use of signal generators without particularly high quality specifications is possible. Thus, use of less exact components in generation and detection is possible.

A method for the control of motor driven adjustment devices in motor vehicles, the method comprising:
- generating a signal representing the speed of a motor by a partitioned signal generator coupled with the motor;
- detecting the signal representing the speed of the motor by a detector associated with the partitioned signal generator;
- generating an output signal corresponding to the signal representing the speed of the motor;
- evaluating the output signal by a control unit;
- and
- adjusting the speed of the motor as a function of the output signal,
- wherein evaluating the output signal includes taking into account tolerance-associated characteristics of the signal generator partitions.
