Definitions

• the invention is based on an information carrier according to the type of the main claim.
• An information carrier is already known, with additional ones
• Information about hotels, restaurants, tourist sights, etc. is stored in text form and can be called up and displayed optically by the user (MERIAN scout operating instructions, MERLAN scout editorial team, Gräfe and Unzer Verlag GmbH, Kunststoff). Information that goes beyond the plain text form is not provided.
• the information carrier according to the invention with the features of the main claim has the advantage that, in addition to the text information, additional information is stored on the information carrier in multimedia form, i.e. in the form of images, sequences of pictures, films, sound and music documents or in mixtures of these forms .
• multimedia form i.e. in the form of images, sequences of pictures, films, sound and music documents or in mixtures of these forms .
• the user can be much more comprehensive Inform about special objects on the route or at the travel destination without using additional material, such as a travel guide. Objects with a tourist significance such as hotels, restaurants, theaters, museums, churches,
• Natural monuments special buildings such as palaces and castles, parks, baths and lakes.
• Criteria can be output.
• the user can e.g. inform about objects that are on the further course of the route during a break.
• the fact that at least one generic term is assigned to the information on the particular objects enables a targeted search.
• a generic term represents a category such as Represents "hotel” or "museum”, which can be specified by further subdivisions e.g. "Hotel”, "2 stars” or “Museum”, "modern art”.
• the user can also be enabled to find out about the location and appearance of the nearest workshops.
• the information can be output automatically depending on the vehicle position. This relieves the user of the elimination of the search effort, so that the driver can obtain information even while driving, particularly in the case of music and sound documents. Additional information does not have to be searched for, so that on the one hand the user is also made aware of objects that were previously unknown to him. By the user restricting other criteria such as the maximum Distance or a generic term such as "hotel", he can limit the output to information that is important to him.
• information on the operation of the motor vehicle and its components is stored on the information carrier.
• this can be information in the event of a vehicle defect, which is automatically called up in the event of a corresponding fault.
• the acoustic and / or optical output of the navigation device into which the information carrier is inserted can also be used to output this information.
• information on the special objects can be called up by radio from the navigation device according to predefinable criteria.
• Information is transmitted from the service center to the navigation device via a downlink channel. This data can be updated by the service center. Furthermore, no storage space is required for permanent storage in the navigation device.
• the navigation device has an uplink channel.
• the uplink channel it is possible to request additional and / or updated information that is transmitted via the downlink channel.
• This data can in particular be the basis for a change in the selected route from a current occasion.
• addresses in particular Internet or WWW addresses, can already be stored on the information carrier.
• a reservation can be made via the uplink channel and a confirmation of this reservation can be made via the downlink channel, because for the user there is the possibility, for example, of displaying an object - e.g. a restaurant or a theater - a table or to reserve tickets.
• the information that can be called up by radio is supplemented with information stored on an information carrier in a multimedia form.
• This allows data transfer to current information - e.g. Limit the occupancy of a hotel, while memory-intensive information is available on the information carrier - e.g. a photo of the hotel.
• a second device for playing an information carrier can be connected to the navigation system, on which only the additional information is stored. This offers the advantage of being able to cover a larger map area with both information carriers, for which navigation and additional information are provided.
• the sound is output via the car radio, because this saves an additional sound output on the navigation system.
• the implementation of the uplink and downlink channel via a GSM connection or the implementation of the downlink channel via A DAB connection offers the advantage that a mobile telephone that may be present in the vehicle and has a GSM connection, or a DAB receiver, is also used by the navigation system. It can also be shared with an existing videophone if the uplink and / or downlink channel is realized through a videophone connection.
• FIG. 1 An embodiment of the invention is shown in the drawing and explained in more detail in the following description.
• the single figure shows a navigation device according to the invention with connected devices and radio connection via an uplink and downlink channel.
• a navigation device 1 according to the invention with a CD drive 2 is shown.
• the connections of the navigation device 1 to sensors and a GPS receiver, which are used for the location, and the computer and storage units present in the navigation device are not shown.
• the navigation device 1 is connected to an audio output 3, the output being able to take place either directly or via an audio output.
• the audio output 3 is preferably implemented by a car radio.
• the video output 4 is connected to the navigation device 1 either directly or via a video output.
• input devices 5 for the user are connected to the navigation device 1.
• An is optional additional CD drive 6 can be connected to the navigation device 1.
• a GSM transmitter and receiver 7 is also connected to the navigation device. It is used to pass on information to a service center 9 via an uplink channel 8.
• the uplink channel 8 via GSM also functions as a downlink channel from the service center to the navigation system 1 via the GSM receiver 7.
• a DAB receiver 10 is connected to the navigation system 1. The receiver is used to receive information from a via a downlink channel 11
• Service center 12 to receive.
• the service centers 9 and 12 may be directly connected to each other; they can also be identical. There is also the possibility that the service centers 9 and 12 are connected to a data network 13, e.g. the Internet, are connected. A connection of the service centers 9 and 12 and of the data network 13 to computers which do not relate to the special objects on the route, e.g. belong to a hotel.
• the information is available in multimedia form, i.e. in the form of pictures, sequences of pictures, films, sound or music documents or in the form of mixtures of these forms. They are stored as data, preferably in the form of various files, on the information carrier.
• an image sequence is understood to mean the sequence of several images that the eye can clearly separate from one another in contrast to a film.
• the information carrier is preferably a CD-ROM, a DVD or a semiconductor component is also possible.
• Information about the type of special objects explained above, in particular with tourist significance, is stored.
• the information is linked to location information.
• the navigation system can now output information depending on the current vehicle position by comparing the current vehicle position with the stored location information.
• the location information represents a position in a digital map and can be represented by a point, a line or a vector or an area on this digital map, which the navigation device can access.
• the location information can relate to the real point of the object or to a position on a street which is to be assigned to the object. For example, a branch to a hotel or a point of interest on another river side could be marked with such a position.
• the card information preferably in the form of a digital card, can also be stored, for example, on the data carrier located in the CD drive 2. The user can, for example, specify whether all stored information about the surroundings of the vehicle, for example within a radius of 1 km, should be output or whether information about the desired route to be traveled, for example the next 3 km, should be displayed.
• the navigation system automatically compares this area with the current vehicle position. If objects about which information is available now come through the vehicle movement into an area predetermined by the user, the navigation device automatically outputs this information.
• Another possible criterion for the selection are generic terms of objects. Different generic terms can eg hotels, inns, theaters, museums or churches. Such a generic term can be stored on the information carrier in addition to each object with the information. For example, the driver can have information about all hotels or all museums displayed. This criterion can be linked to the selection of a local area, e.g. all hotels within a radius of 10 km.
• the input is also made via the input device 5. Furthermore, the user can output the information independently of the vehicle position when prompted via the input device 5. The output takes place via the audio output 3 and / or via the video output 4.
• the video output 4 can take place via various devices.
• One possibility is to connect the navigation system 1 to the display of a freely programmable instrument cluster. At the request of the user, the information is then shown on the display.
• the video output can also be implemented by a screen, preferably in the center of the vehicle, or also by a head-up display, in which the image is projected onto the windscreen.
• the input device 5 can be designed in various forms, one or more of which are available to the user.
• the input into the navigation system 1 can take place via a keyboard, via a microphone connected to a voice input evaluation, or via a screen with a menu selection.
• the input device 5 has a microphone and a camera of a videophone, and a direct contact can be made with the service center 9 via the navigation system 1 and the uplink and downlink channel 8.
• a trip along the Middle Rhine is chosen as an example of the diverse way in which information can be stored on the information carrier.
• Historical information about the castles can be output as a sound document, for example; the Lorelei song can be played at the Lorelei, the timetables for the Rhine shipping can be displayed and tickets can be reserved via the uplink channel become. It is also possible via the downlink channel to find out current information about prices and occupancy of the hotels or to find out about the range of restaurants. Short films about the places you pass can be shown, especially for the front seat passengers, for example to give a decision as to whether a stop should be made. Since the navigation system continuously determines the current position of the vehicle, the user, if the automatic system is activated, is provided with information about the objects which he can currently see in his surroundings.
