Abstract: The described navigation system makes use of the attribute pertaining to the existence of “preferred directions,” in particular, inside multi-story car parks. These preferred directions are not limited to a plane or to an orientation. Preferred directions are, in particular, longer entry and exit paths. The method detects a departure from the digitized area and then determines a preferred direction that is defined as a principle axis or a principle axis direction. When traveling within the non-digitized area, e.g. of a multi-story car park, the system monitors whether the vehicle moves within a predetermined limit of the previously defined principle axis direction. If this is the case, it is determined whether a deviation exists and this deviation is optionally corrected to conform with the principle axis direction. This enables compensation of errors that are caused, in particular, by the direction detection.

Abstract: In a data memory (2) which is arranged in a vehicle, an interface (6), which is equipped with a plug connection (5), is used to connect a receiver unit (1). The individual software modules which, depending on the design, are necessary for decoding the signals of the receiver unit (1) may be called up by means of a memory unit (7) for the data memory (2). The memory unit (7) is arranged at the interface (6). A precautionary storage of all the relevant software modules in the data memory (2), and the associated laborious manual configuration can thus be eliminated and incorrect assignment of the software module to the existing receiver unit (1) may be avoided. At the same time, new developments in the field of software modules may be incorporated into already existing data storage systems without difficulty.

Abstract: An indicating instrument for a vehicle includes an analog indication of the current measured value and has a variable indication of a reference value. An automatic setting device indicates the reference value based on variable data that are significant for the indicated measured variable. The entire indicating instrument is rotated by the setting device so that the pointer is aligned horizontally when the current measured value agrees with the reference value.
