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. ## Claims ### Claim 1 A system comprising a user interface (300) adapted to presenting map data Dmap in a vehicle, characterised by an analysis unit adapted to analysis of map data Dmap, involving determination of a quality Q for said map data Dmap, which analysis unit is adapted to basing said determination of said quality on whether said map data Dmap are available and/or reliable, and a presentation unit adapted to graphic presentation of said quality Q. ### Claim 2 (depends on 1) A system according to claim 1, in which said analysis unit is adapted to determining said quality Q on the basis of any one of the following: whether map data Dmap are available or not, reliability of available map data Dmap, reliability of self-estimated map data Dmap,est, and reliability of a sensor fusion which pools sundry self-estimated map data Dmap,est. ### Claim 3 (depends on 1, 2) A system according to either of claims 1 and 2, in which said analysis unit is adapted, when making said determination of said quality Q, to giving said map data Dmap at least one of the following quality values: reliable map data Dmap,rel, unreliable map data Dmap,non-rel, reliable self-estimated map data Dmap,est,rel, unreliable self-estimated map data Dmap,est,non-rel, lack of map data Dmap,lack. ### Claim 4 (depends on 1, 2, 3) A system according to any one of claims 1-3, in which said analysis unit is adapted to determining individual values for said quality Q within the scope of at least one of the following: a geographical area, a road, and a segment of a road. ### Claim 5 (depends on 1, 2, 3, 4) A system according to any one of claims 1-4, in which said presentation unit is adapted to using different graphic features for different values of the quality Q. ### Claim 6 (depends on 1, 2, 3, 4, 5) A system according to any one of claims 1-5, in which said presentation unit is adapted to using at least one of the following indications: a first graphic feature to indicate reliable map data Dmap,rel, a second graphic feature to indicate unreliable map data Dmap,non-rel, a third graphic feature to indicate reliable self-estimated map data Dmap,est,rel, a fourth graphic feature to indicate unreliable self-estimated map data Dmap,est,non-rel, and a fifth graphic feature to indicate lack of map data Dmap,lack. ### Claim 7 (depends on 5, 6) A system according to either of claims 5 and 6, in which said graphic features comprise at least one of the following: colours, patterns, symbols, and signs. ### Claim 8 (depends on 1, 2, 3, 4, 5, 6, 7) A system according to any one of claims 1-7, in which said user interface forms part of a navigation device which combines said map data Dmap with positioning information. ### Claim 9 (depends on 1, 2, 3, 4, 5, 6, 7, 8) A system according to any one of claims 1-8, adapted to providing the graphic presentation of said quality Q during navigation. ### Claim 10 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9) A system according to any one of claims 1-9, adapted to providing the graphic presentation of said quality Q in conjunction with using a cruise control. ### Claim 11 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) A system according to any one of claims 1-10, adapted to making its own internal estimate of data related to said map data Dmap if said analysis by said analysis unit shows that said map data Dmap fall into any of the following categories: unreliable map data amap,non-rel, unreliable self-estimated map data Dmap,est,non-rel, and lack of map data Dmap,lack. ### Claim 12 (depends on 11) A system according to claim 11, in which said internal estimate of said data is used by said system after said estimate has been made. ### Claim 13 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) A system according to any one of claims 1-12, in which said analysis unit is adapted to determining said quality Q on the basis of comparison of said map data amap with data related to said map data Dmap, said quality Q being determined by the magnitude of a difference between said map data Dmap and said data related to said map data Dmap. ### Claim 14 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) A system according to any one of claims 1-12, in which said analysis unit is adapted to determining a quality Q for an internal estimate Dmap,est of data related to said map data Dmap on the basis of comparison of said internal estimate Dmap,est with data related to said map data Dmap, said quality Q being determined by the magnitude of a difference between said internal estimate and said data related to said map data Dmap. ### Claim 15 (depends on 13, 14) A system according to either of claims 13 and 14, in which said data related to said map data Dmap are based on at least one of the following: map data other than said map data Dmap, data related to a vehicle speed predicted by a cruise control, data related to an estimate based on a force equation for said vehicle, data related to an estimate based on an accelerometer on board said vehicle, data related to an estimate based on an altitude change for said vehicle, and data pooled from at least two estimates. ### Claim 16 (depends on 13, 14, 15) A system according to any one of claims 13-15, in which said analysis unit is adapted, when determining said quality Q, to comparing said magnitude of said difference with at least one magnitude range. ### Claim 17 (depends on 16) A system according to claim 16, in which said analysis unit is adapted to determining limits for said at least one magnitude range on the basis of a current running situation of said vehicle.
