Information input

The invention relates to information input for a navigation device for road vehicles, wherein a map, in particular a map containing a street representation, map markings can be assigned which represent "optically readable information" and which can be detected by a reading device and can be fed to a data processing unit of the navigation device.

With such information input, it is known to use maps in the form of slides that on a viewing device can be projected. To identify the Each desired slide is attached to its edge by lines formed markings that are optically readable and enable a machine sorting out of the desired slide. Light markings on the projected map. show the respective location.

There is no individual input of the starting or destination point in the navigation system. About that

In addition, a large amount of equipment is required, the disadvantageous both for reasons of space and costs is.

It is therefore an object of the invention to provide information input according to the generic term to create that with simple Means an easily manageable individual input of data, in particular the data of the start or Target point allows. '·

This object is achieved according to the invention in that a mark can be assigned to a start or destination point on the map and optically readable localization markings can be detected by the reading device in the assigned state of the mark to the start or destination point. By simple assignment of the mark to the starting or destination point and subsequent optical reading by means of the reading device it is easy to enter the start and destination information into the data processing unit. Urstand-0 Lich coordinate measurement in the maps as well as input units with keypads for entering the number values are not required.

The localization markings preferably represent coordinate values and can be vertical and horizontal grid strips.

To indicate to the data processing unit that the reading of a raster strip has ended and which of the raster stripes that have just been scanned, an optically readable end mark and / or raster stripe identification can be arranged.

The mark that can be assigned to the start or destination point can be easily identified by a vertical or horizontal be formed running reference line. If a plurality of maps are available, the ones on the Map markings attached to the map contain information identifying the map, so that the entered coordinate values are also assigned to the correct map.

Beyond this input data, optically readable Programming commands for further steps of the data processing unit to be carried out by the navigation device be accessible.

Numerical values that can be assigned to these special programming commands can thus be fed to the data processing unit, that optically readable numerical codes can be assigned to the programming commands.

The map markings on the map and / or the programming commands and / or the numerical codes are preferably used formed by barcodes.

Reading this information is easy because the location markers and / or the map markers and / or the programming commands and / or the numeric codes are optically readable using a light pen, This enables space and equipment requirements as well as manageability in a motor vehicle meaningfully applicable information input for navigation systems.

The ease of use is enhanced by this,

that the light pen can be guided on a guide edge along the optically readable markings. Such Leading edge enables a perfect fit even in the tight spaces available in motor vehicles Scanning with the light pen.

To avoid reading the markings in the wrong direction, you can use the optically readable markings with Reading direction signs should be provided - which point in the direction in which the light pen is to be guided.

An advantageous embodiment of the information input is that one template is the mark and the localization markings having. By simply placing the template at the start or destination point on a map, e.g. an auto atlas and subsequent optical reading by means of the reading device is a simple input of the Start and destination information possible in the data processing unit.

The reference line forming the mark can pass through a vertical or horizontal edge of the template be formed, which can be applied to a corresponding reference line on the map.

In an advantageous embodiment, the template can be a A plurality of maps can be assigned.

Beyond the localization markings as well as the brand the template can have the map markings and / or the programming commands and / or the numerical codes! ·. This means that all the necessary read-in data are on one single component arranged.

In another, also advantageous embodiment of the Information input can be the map with the mark and / or the localization markings and / or the Map markers and / or the programming commands .5 and / or the numerical codes. This enables particularly simple handling in terms of readability.

The optically readable markings can be imprints on the map or else by means of preprinted ones Stickers must be applied to the maps.

If the map can be applied to a carrier that can be provided with the optically readable markings, then in a simple Way any map can be prepared for use by entering the information described.

In order to facilitate the reading process, the carrier can be a relatively rigid carrier plate.

If the map can be covered by a transparent cover, it is protected against damage.

However, this cover can also have a plurality in the coordinate directions have guide lines running to the localization marks through which the correct starting point for the light pen on the localization marks can be fixed more easily and correctly.

In a simple and easily manageable design, the cover can be a film.

Embodiments of the invention are shown in the drawing and are described in more detail below.
