Brief description of the drawings

following the invention will be explained in more detail with reference to figures. Hereby shows:

1 a schematic view of a first embodiment of the system according to the invention;

2 a schematic view of a second embodiment of the system according to the invention;

3 a schematic illustration of a first representation; and

4 a schematic illustration of a second representation.

embodiments the invention

In 1 schematically is a first embodiment of a system 1 to provide a route.

The system 1 comprises a storage device 4 , in the geographical positions, z. B. from a road map, are stored.

Furthermore, the system includes 1 a position sensing device 7 , via which a user can enter geographical positions via a keyboard (not shown here) or similar input means, e.g. B. start position and target position of a route whose history the user would like to have calculated.

The calculation of the route takes place in a route calculation device 11 connected to the position sensing device 7 and the storage device 4 communicates. The user gives the desired positions via the position picking device 7 to the route calculation device 11 and this accesses the storage device 4 to calculate a suitable route. "Appropriate" here means that it can be either the shortest route between start and end position, or a desired by the user route with certain intermediate positions. There are also other known from the prior art route types conceivable, the specifications for a particular route type also on the position recording device 7 can be entered by the user.

The route calculation device 11 then gives the calculated route to a presentation calculator 15 that the route z. B. calculated as a two-dimensional or three-dimensional representation, which then on a display device 19 , such as As an LCD screen, is displayed and can be perceived by the user.

With the presentation calculation device 15 it is still possible on the display device 19 a simulation of a movement of an object, such. As a motor vehicle to represent along the calculated route.

Via a parameter input device 23 associated with the presentation calculation device 15 in connection, can, for. B. on the keyboard of the position sensing device 7 , Parameters are entered that can change the appearance or view of the object. This should be based on the 3 be clarified.

3 shows as an object a representation of a motor vehicle 27 and an imaginary camera 31 which is to correspond to the eye of an observer who is on the in 1 illustrated display device 19 looks. The imaginary camera 31 is arranged at a distance l from a reference point B. The reference point B is in the illustrated example in the motor vehicle 27 , being the imaginary camera 31 directed to the reference point B. The reference point B and the distance l are from the user via the parameter input device 23 pretend. Likewise, in the case of three-dimensional representation, the perspective must be specified by the user, from which the imaginary camera 31 the car 31 considered, ie the solid angle area in which the imaginary camera 31 is arranged, based on the reference point B. In the example shown in FIG 3 appears on the display device 19 in 1 a representation of the rear of the vehicle 27 from obliquely behind right, where the image detail, ie the ratio of vehicle view to view of the vehicle environment, by the user via the parameter input device 23 can be specified.

Does the virtual vehicle move? 27 now from a position I along the route R to a position II, the imaginary camera follows 31 the vehicle 27 because the distance l between imaginary camera 31 and vehicle 27 and the perspective is fixed. Thus, the view remains on the vehicle 27 in a moving vehicle 27 unchanged, ie a relative angle α between the viewing direction of the imaginary camera 31 and the direction of movement of the vehicle 27 stay constant.

It is of course also conceivable that the representation of the vehicle 27 is also related to a reference point outside the vehicle 27 Nevertheless, the reference point is still rigid with the vehicle 27 moved. This case is hinted at with an imaginary camera 31 ' pointing to a reference point (not shown) next to the vehicle 27 is directed. During a movement of the vehicle 27 In any case, the user has the impression with the vehicle 27 to ride as an observer.

About the in 1 illustrated parameter input device 23 the user can also enter parameters that change the appearance of the in 3 shown vehicle 27 change. Thus, the user can specify which specific vehicle model is to be displayed, in which color, in what equipment, size, etc.

In 4 is another form of representation to be seen, it being noted that in the in 4 elements shown the same reference numerals as in 3 but with an appended letter a to make it clear that this is another embodiment.

A vehicle 27a is represented in a position I, again an imaginary camera 31a to symbolize the viewing position of a viewer. The vehicle 27a in turn moves on a calculated route Ra from position I to position II.

Although the imaginary camera 31a again at a fixed distance la from the vehicle 27a is arranged (for example, based on the center of the vehicle 27a ), is the imaginary camera 31a now directed to a fixed reference point Ba, the z. B. may be a distinctive building or other with a fixed geographical position. It is important that the reference point Ba does not coincide with the vehicle 27a but with a movement of the vehicle 27a is always directed to the reference point Ba.

About the in 1 illustrated parameter input device 23 As described above, the user again sets the perspective or the appearance of the vehicle 27a firmly.

In 2 is another embodiment of a system according to the invention 1' shown. The structure of the system 1' is largely analogous to the structure of in 1 illustrated system 1 , which should be clarified by the primed reference numerals.

The system 1' comprises a storage device 4 ' , a position-receiving device 7 ' and a parameter input device 23 ' a route calculation device 11 ' and a presentation calculation device 15 ' , as well as a display device 19 ' , Unlike the in 1 illustrated system 1 includes the in 2 illustrated system 1' but additionally a detection device 35 in the example shown a unit with the route calculation device 11 ' forms, but can also be arranged separately.

The detection device 35 is designed to maintain a current geographic location e.g. B. a vehicle to detect. Basis for the detection of the current geographical position bil the signals from one or more satellites, mobile signals, radio signals or other electromagnetic signals.

The system 1' can then be used to have a route calculated from its own current position to a desired destination position, and the own vehicle and the route in one of the above-described ways of presentation on the display device 19 ' to be shown.

However, it is also conceivable that the detection device 35 can receive and process appropriate signals for the detection of current geographical positions of multiple vehicles simultaneously, so that a route between these moving vehicles is calculated, one vehicle is a (moving) start position and the other vehicle is a (moving) target position.

Furthermore, it is conceivable that the detection device 35 Signals, e.g. B. by satellite, for access to the Internet can receive.

It should be noted that the route calculation device 15 respectively. 15 ' is designed so that it can receive information based on which the current route is recalculated. This can z. B. traffic information about currently existing congestion, construction sites, etc., or input from the user who wants to change the route. The inputs from the user can be made manually via the position sensing device 7 respectively. 7 ' done, or z. Via voice control (eg Bluetooth).

It is also conceivable that the system 1' can be connected to a mobile device, allowing the user both the system 1' as well as the connected mobile device z. B. can operate voice control, which is particularly great for motorcyclists.

The system 1 respectively. 1' can z. B. may be permanently installed in a motor vehicle, but it may also be designed as a mobile system or implemented in a PC.

Furthermore, it is also possible for the user to access the storage device 4 respectively. 4 ' to update existing data, or to save or load certain routes for recall at a later date.
