The present invention provides a mechanical interface apparatus () for a motor drive unit () in motor vehicles, in particular in a motor vehicle door, which is firmly connected to the drive unit () and has holding and guide devices () for holding a control or plug unit (), with a cut-out (), which passes all the way through, being formed between the interface apparatus () and the drive unit () in order to pass through at least one plug contact (), a component mount () or the like for the control or plug unit (); and with at least two guide devices () being provided in or close to the drive unit () for guiding the plug contacts () and/or the component mounts () or various control or plug units () of this type.

Mechanical interfaced system

A motor-driven window lifter for a motor vehicle with electronic means to protect against entrapment of body parts in the window opening with at least one spring in the line of force between the drive unit (such as an electric motor or gear) and the window pane is characterized in that the blocking force of the spring corresponds at a maximum to the sum of the displacement force anticipated and the admissible entrapment force and that the spring characteristic when an initial load is exceeded has a decreasing, preferably negative curve, such that the spring enables a relatively long path of the drive unit when the initial load is exceeded.

Electromechanical control unit for adjusting devices in motor vehicles

The present invention provides a method for detecting the position, direction of rotation and rotational speed of a rotatably seated part, which are employed, for example, in particular in externally-operated locking parts of motor vehicles (e.g., with an electric window opener with protection against jamming). The method allows a reduction in the number of components and installation space. The method of the present invention has the feature that control commands and the state of the motor are provided to a logical evaluation device. Either the high and low edges of the digitized signal, or one of the high or low edges, together with the signal level at the time of motor start or reversal of the direction of rotation of the motor are assigned to the one or the other direction of movement (direction of rotation).

Method for detecting the position, direction of rotation and rotational

The invention relates to a process for detecting the position and direction of movement and for detecting the dynamic characteristic values of remote-controlled displacements of an adjustable object. According to the invention a signal is detected and evaluated which is solely made up of a system-characteristic signal or the overlapping of several system-characteristic signals. The aim is to achieve a high dissolution of the aforesaid values which are to be detected without using additional sensor or transmitter elements whilst incurring only small production costs.

An apparatus for measuring at least one state variable of a brushless direct-current motor includes 2 * n pole segments, wherein n=1, 2, 3, etc.. The pole segments are integral with a rotor of a brushless direct-current motor and are formed of permanently magnetic material generating a magnetic field. At least one Hall-effect element supplies an output voltage and is disposed in the vicinity of the rotor for impressing the magnetic field of the permanently magnetic segments on the output voltage from the at least one Hall-effect element. A logic unit receives the output voltage from the at least one Hall-effect element for determining the temperature of the brushless direct-current motor.
