DE202005014631U1 - Navigation apparatus with position determining unit arranged to image all information or road signs on a display unit - Google Patents

Abstract

The navigation device has a position determining unit, electronically stored map data, a data processor for calculating a route to the desired target using the map data, and a display unit to display information provided from the data processor to follow the calculated route. The device has stored therein information regarding road signs and instruction signs provided along streets or other routes. The device is arranged such that at least those signs to be observed along the route are displayed on the display in an appropriate image format.

Description

The The invention relates to a navigation device according to the preamble of Claim 1.

such navigation devices have long been known and become both stuck in vehicles built-in devices as well as detached as mobile devices offered. The user can enter a desired destination in the device, the device then uses the map data to calculate a route or several possible routes, which it then outputs to the user on the basis of information displays or driving instructions. Often becomes a two-dimensional representation of a road map used in which markers indicate the route.

The abstract, two-dimensional representation of a road map in the actual To transmit the environment falls many Heavy users. This is particularly important in navigation because decisions must be made within a short time. Previous navigation devices They were of little help, as they are still the driver could only give abstract driving instructions.

• – Piktogramme, die stark abstrahiert den Straßenverlauf andeuten, und
• – gesprochenen Anweisungen wie etwa „in 200m halbrechts halten".

Alternative views to a map view with highlighted route are in known navigation devices:

• - Pictograms that indicate the course of the road in a highly abstract way, and
• - Spoken instructions such as "hold in 200m half right".

None however, these instructions are intuitive and the instructions can be used Users in many cases unsettled, since they are not readily available in many traffic situations are traceable.

task The invention is therefore a known navigation device to the effect continue to develop that it is easier to understand the instructions or hints for following a route calculated by the device.

Is solved This object with a navigation device with the features of the claim 1.

The Representation of signs in a substantially the actual Exemplary replication is an essential help for the User, because instead of an abstract statement like "hold half right", it is a hint gets which he finds easily in the real traffic situation. As a result, he gets security and can, without being distracted by traffic to follow the instructions or instructions of the navigation device.

Uses according to the invention the navigation device in the device stored information about the signs along the way, especially on highways and federal roads. This information may be preferred in the Kar tendaten be contained. You can also in the navigation device Being saved separately from the map data will then become more meaningful Way associated with these. The navigation device can also receive the information from an external device. In this context, "in the navigation device saved "too in the sense of short-term storage in a working memory to be understood. The driving instruction is at least supported by Display of a substantially the actual model Illustration of the road sign to be followed, e.g. an exit sign. The appearance is adapted to the design of the actual signage, so that the user can easily find the signs on the basis of the presentation recognize and follow accordingly. Signs on german Highways e.g. will appear in the ad according to the example in blue with white Signs, signs on german federal highways according to yellow with black signs, represented. Signs abroad are reproduced according to the local design.

The corresponding data via this framework of the appearance of the signs (e.g. Coloring in dependence of the road type) can while in the information about the signage is integrated, however, it is preferable that this information is stored as a separate record in the navigation device are the data processing unit for the determination of the actual Ad accesses. This separate record can then be country-specific information about the design of the signs included so that the navigation device highway signs in Germany on a blue background, in e.g. Denmark but as usual on green Reason.

Further advantages and features of the invention will become apparent from the following description of an embodiment with reference to the attached 1 , This figure represents the ad 1 a navigation device, as it outputs a driving instruction (hint displays) for following a precalculated route.

Part of this ad 1 is initially a pictogram-like representation 2 the course of the road at the current geographical location, here the road in the area of a motorway exit, in which representation of the given route by highlighting 3 and a follow-up arrow 4 is marked. Further, in the fields 5 and 6 Pictographically branching or crossing situations represented by arrows 7 . 8th that the one to choose Specify the direction of travel at the next two branches or intersections. It is also in a title block 9 the place shown, where the driving instructions to follow, here the junction Unterhaching-east on the federal highway A8.

at 10 is finally according to the invention as a further indication of a substantially true to the original representation of the real attached to the highway exit sign in the display 1 displayed. This illustration is like the real sign on the highway given in white on a blue background and also includes other traced to the model details such as a white outline and the white dialed, white circled exit number. This close-to-reality presentation of the information sign actually available on the road facilitates orientation for the user.

In addition, can the navigation device in this situation still acoustic driving instructions such as "at the next exit turn right, then next Exit right ".

The embodiment is for explanation only of the invention and is not limiting.
