Abstract:
The present invention relates to an electronic controlling device with a computer unit installed to control a regulating device especially a window lifter of a motor vehicle. The computer unit stops or initiates the stop of a regulating motion of the window lifter drive if a signal correlating to the rotary moment of the window lifter drive exceeds a response level. In the setting range of a starting motion from standstill of the window lifter drive, the response level is a setting range dependant and/or time-related dependant preset function with at least one parameter determining the course of this function. The parameter value is modified in dependence from the starting motion of the window lifter drive.
Abstract:
The invention relates to a method for producing ionic liquids and ionic solids which takes recourse to a novel, especially modular production process. According to the inventive method, those salts from an ionic carbonate, hydrocarbonate or monoalkyl or monoaryl carbonate precursor (cationic synthesis module) are produced that comprise the desired quaternary ammonium, phosphonium, sulfonium or the analogous quaternary heteroaromatic cation. This precursor can be produced and stored efficiently and with a high degree of purity. The actual process for producing the desired ionic compound, which comprises the introduction of the desired anion, is, unlike generic production processes known so far, flexible, fast and generally applicable. In a preferred embodiment, the carbonate, hydrocarbonate or monoalkyl or monoaryl carbonate anion is completely removed in the form of a gaseous carbon dioxide by reaction with any Brønsted acid (anionic synthesis module) and is replaced by the anion that is conjugated to acid. The invention thus allows the production of a plurality of varied ionic liquids and ionic solids on the basis of any industrially producible ionic precursor in a fast and efficient manner (modular production method). In another embodiment, the same ionic carbonate precursors that comprise the desired quaternary ammonium, phosphonium, sulfonium, or analogous quaternary heteroaromatic cation are reacted with suitable metal salts (e.g. calcium, strontium, barium, zinc or manganese salts), whereby the carbonate anion of the precursor interacts with the metal cation to give a poorly soluble carbonate (e.g. calcium, strontium, barium, zinc or manganese carbonate) which is then precipitated. The carbonate of the ionic precursor is replaced (metathesis reaction) by the anion of the added suitable metal salt (anionic synthesis module) and the desired ionic compound can be isolated by filtration once the poorly soluble carbonates are removed.

Abstract:
An electronic controlling device with a computer unit installed to control a regulating device especially a window lifter of a motor driven vehicle is provided. The computer unit stops a regulating motion of the window lifter drive or starts a program to stop the regulating device of the window lifter drive, if a signal correlating to the rotary moment of the window lifter drive exceeds a response level. In the setting range of a starting motion from standstill of the window lifter drive, the response level is a setting range dependant and/or time-related dependant preset function with at least one parameter determining the course of this function, which value is modified in dependence from the starting motion of the window lifter drive.
Abstract:
A method for controlling a synchronous motor driven adjustment device is used in motor vehicles by means of an electronic control, especially for controlling adjustment devices with an anti-trap protection and/or with an excess force limitation. The method includes evaluating variables correlating to the dynamics of the adjusting device or the position of the adjustment member and generating control signals based on the variables, controlling the adjustment rate of the adjustment member to a constant value, and setting a phase displacement between an exciting field and a rotating field of the motor to provide torque to the drive unit based on the load angle at which the torque reaches a maximum.
Abstract:
A switching device and process for external force-actuated driving devices in a motor vehicle, especially windows and sliding roofs. Depending on the dynamics and/or degree of displacement of an actuating component, control signals are generated which code the displacement speed and travel, the position, the displacement duration and/or direction of the item to be displaced. The actuating component is preferably an unrestrictedly rotatable component which, during its rotation, generates control signals for an electronic control unit. The device and process give a user the greatest possible control over the displacement of the component.

Abstract:
The invention relates to an operating method for an electric window lifter for moving a rear pane (3) in a motor vehicle, in which the rear pane (3) is moved in a lowering direction (−z) along an approximately s-shaped path of movement. In the case of trapping, the movement of the rear pane (3) in the lowering direction (−z) is stopped and the rear pane (3) is moved in the lifting direction (+z).
