Abstract:
A method and device for controlling a fluid-actuated control system, to optimize post-switching times for actuation of control elements in such systems. The system includes at least one pressure medium source, at least one hydraulically controlled control element and a device for controlling the fluid-actuated control system. The optimum post-switching time after hydraulic actuation of the control element, depends on a number of different factors such as a control-element-specific parameter, a specific mounting location of the control element, at least one operating parameter of the fluid-actuated control system and/or of the vehicle. A post-switching time control device controls and/or regulates at least the duration of a post-switching time of the at least one control element and with the above factors determines the post-switching time.
Abstract:
A method for determining an actuating pressure of an operating element (1), for example in a motor vehicle, where the element is displaced as a result of the application of the actuating pressure. The actuating pressure of the operating element is determined without the use of a pressure sensor by way of deformation measurement.

Abstract:
A constructional unit has a frame and a cover. The frame and the cover are formed of materials with different coefficients of thermal expansion. A plurality of spacers is arranged between the frame and the cover and defines a gap therebetween. An adhesive is provided in the gap to attach the frame to the cover and simultaneously seal the gap.
Abstract:
A device for the protection of stamped conducting paths particularly in a motor vehicle. The device having a complete envelope (4) around the conducting paths which can be made from a sprayed elastic material.
Abstract:
The present invention concerns a method and a device for machine diagnosis and, in particular, for transmission diagnosis in a machine or motor vehicle. The measurement system, according to the invention, comprises a coil (2) wound on a coil core (11), on the surface of which ferritic wear particles (3) to be detected accumulate. Opposite the coil (2) a rotating toothed wheel (6) is arranged which influences the inductance of the coil (2). The output signal of the coil (2) is pulsed with a constant amplitude, the pulse frequency depends on the rotation speed of the toothed wheel (6). Deviations of the amplitude are attributable to the accumulation of ferritic wear particles (3) on the coil (2) and therefore provide a measurement of the condition of the machine or transmission.
