In accordance with a method of and arrangement for representing point-referenced travel guiding information, especially in power vehicles on a display of an electronic guiding and orienting device, a desired travel route is input, and a travel guiding information is represented at a distance from a reference point determined in accordance with the vehicle speed.

Method of and arrangement for representing travel guiding information

To provide a suitable number of display fields (e.g. ARRIVAL; TIME; etc.), each of which characterizes and identifies the significance or import or meaning of a displayed numerical value on a display device (16), the display fields are associated in groups or sets (11-15; 42-45) having a particular geometric position (columns; segmental), and a plurality of keys (21-25) are provided with each key being associated with a group or set of the display fields, and connected to a counter (61) to select a particular one of the display fields within the group or set by the number of key operations, the numerical value associated with the display field then being displayed on the numerical display (16). The display and keys are connected to a computer (62) which provides the output data for the numerical indicator (16); an input/output control switch (26) is provided to change the function of the display group selection keys (21-25) to permit data entry into the computer (62), for example of speed limit, driving distance, and the like.

A Wiegand wire is placed within the magnetic field generated by a first and second permanent magnet. The first permanent magnet has a field strength exceeding that of the second permanent magnet and the polarity of its magnetic field is opposite that of the second magnet. A rotor having segments of magnetic shielding alternating with slots is rotated between the Wiegand wire and the first magnet. When the magnetic shielding is between the first magnet and the Wiegand wire, the latter is exposed only to the magnetic field of the second permanent magnet. In a second position of the rotor, the Wiegand wire is exposed to both magnetic fields. Since the second permanent magnet generates a stronger field than the first, the direction of magnetization in the Wiegand wire changes abruptly causing a pulse to be generated in pick-up coil 4.

The movable body is supplied with at least two marker elements to move therewith, the reference being at a fixed location at which a stationary transducer is located responsive to the marker elements and to provide output signals staggered in time as the marker elements pass by the transducer, so that the marker elements in combination with the transducer form a pulse source. The individual marker elements are different to provide pulses having respectively different characteristics, which pulses are conducted to threshold stages which, in turn, are connected to a logic circuit to evaluate and logically combine the respectively different pulses from the pulse source. Different pairs of marker elements, for example associated with different pistons of a multi-cylinder internal combustion engine can be characterized by additional marker elements providing additional pulses which, in combination with one marker element, can characterize a certain number representative, for example, of a cylinder.
