Abstract: A method for determining a rotation variable of a rotatably mounted rotor of a mechanically commutated electric motor, having a motor current path formed between two brush elements of the electric motor, and leading via the commutator bars contacted by the brush elements, and via coil windings of the rotor electrically connected to said commutator bars, wherein an oscillating input signal is fed into the motor current path and the rotation variable is determined with the aid of a ripple of a resultant output signal, said ripple being due to the mechanical commutation of the motor current path.

Abstract: A control device for electronic multi-step gear shifting control of an automatic transmission for motor vehicles functions to shift gears by means of the tip actuation of a selector lever with a shifting journal that can be pivoted from the automatic shift lane into the multi-step shift lane. The control device is configured as a tip shifting module in the form of a compact modular component with a sturdy housing. The tip shifting module serves to secure and hold in place several mechanical modules and electronic modules located therein and convert the mechanical shifting movement of the selector lever imparted on the input side into electric control signals that can be tapped at the output side of the module. A multi-track encoded magnet arranged in the housing of the module together with several Hall sensors ensures a reliable generation of switching signals.
