Graphical user interface

摘要

A system having a user interface which presents map data Dmap. An analysis unit analyzes map data Dmap, determining a quality Q for these map data Dmap which are to be presented. The determination is based on whether the respective map data Dmap are available and/or reliable. The quality Q is presented graphically by a presentation unit. The risk of wrong decisions being taken on the basis of deficient map data Dmap is reduced considerably, since the user can easily decide whether there are reliable map data or not.

1. A system comprising a user interface configured for presenting map data (Dmap) in a vehicle, the system comprising
an analysis unit configured for analysis of map data (Dmap), involving determination of a quality (Q) for said map data a presentation unit adapted to graphic presentation of said quality (Q), and wherein said analysis unit is configured for basing said determination of said quality on whether said map data (Dmap) are available and/or reliable, by a comparison of a vehicle speed being predicted by a cruise control system having knowledge of road sections ahead based on said map data (Dmap) with an actual measured vehicle speed, said quality (Q) being determined by the magnitude of a difference detected by said comparison of said predicted vehicle speed and said actual measured vehicle speed.
