Gearset-drive unit (), in particular for use in motor vehicles, comprising a drive wheel () that meshes with a driven wheel (), wherein a sensor wheel () with a position sensor () that interacts with a sensor () to detect speed meshes with the drive wheel () or the driven wheel ().

Gear drive unit with speed measurement

A method for controlling an electric drive motor () of a motor vehicle adjusting drive by means of applying a variable voltage to it should be improved so that an EMV interference suppression can be inexpensively executed. To this end, a controllable resistor () is used, which supplies the voltage applied to the drive motor ().

The method of electronically monitoring and controlling a process for moving and/or positioning at least one window and/or sunroof of a motor vehicle to provide protection from pinching includes supplying an input variable, for example drive voltage, and an output variable, for example window position, to a detection device; storing a model in the form of a differential equation describing the process for moving and/or positioning the window and/or sunroof in terms of process parameters in the detection device; optimizing the process parameters of the model according to the input and output variables and storing values of the optimized process parameters in the detection device for the purpose of monitoring; continually evaluating current values of the process parameters obtained by the optimizing by comparing the current values with the stored values; calculating a process correcting quantity in the detection device for adjusting the window and/or sunroof according to the comparing and influencing the process by feeding the correcting quantity into the process, so that the process can be halted when pinching is detected.

The invention relates to a method for expanding the absolute angle measurement range in magnetic field sensors. Through the use of an evaluation circuit ( ), various method steps are carried out; first, the ratio of two phase-shifted input values is determined, for example sine signals or cosine signals of the voltage ( ). The ratio of the phase-shifted input values ( ) to each other is combined with an offset C. The predeterminable offset C permits the expansion ( ) of the angle measurement range of magnetic field sensors to a full 360&deg; rotation ( ) or a multiple thereof.
