Definitions

  • the invention relates to a method for operating a navigation system with a display device according to the preamble of claim 1.
  • BESTATIGUNGSKOPIE navigation information is not available on the orientation of the map.
  • the problem is solved in that, in the method for operating a navigation system with a display device, the map to be displayed on the display device is displayed with the precalculated route course in a first representation and that an already laid back part of the route, in particular in a different from the first representation of the second display mode, is displayed on the display device.
  • the type of display device is basically arbitrary. It may be, for example, an integrated screen or the screen of a PDA or mobile phone, on which a navigation software is running. On this display device, a map with the current environment and the precalculated route history is displayed in a first representation. The precalculated route progression represents the planned route piece to be covered in the future.
  • the representation is basically arbitrary. Frequently, for example, the precalculated route course is displayed in the form of a clearly visible bar code.
  • the part of the route already covered represents that route which has been covered wholly or partly from the starting point up to the current position.
  • This already traveled part of the route course is displayed on the display device, in particular in a second display mode different from the first presentation mode.
  • This makes it possible for the user to distinguish between precalculated route course and already traveled part of the route course. This will enable him to identify the part of the itinerary in the map already known to him in reality. Thus, he can relate the already unequivocally identified in the map already covered part of the route history with him known in the real part of the route history and orient themselves to it. In other words, therefore, the different representation of the precalculated route and the already traveled part of the route initially allows a clear distinction and identification on the map to be displayed. Since the user knows from where he came, so he knows the already traveled part of the route in reality, he can set the already traveled part of the route on the map and in reality with each other and thus orient themselves.
  • the second representation that is the representation of the part of the route already covered, can be realized, for example, by different transparencies in the color choice and / or different colors and / or different line thicknesses and / or different patterns and / or different sized position symbols and / or different gray levels ,
  • the display intensity decreases as a function of the time and / or the distance traveled and / or the distance to the current position.
  • the dependence on time can be represented, for example, as a function of the absolute time or depending on the relative time between two locations on the already traveled part of the route.
  • the display intensity may decrease, for example, up to an invisibility of the part of the route already covered.
  • the display intensity decreases starting from the current position in the direction of the past to a specific location on the already covered part of the route, so that from this location the already covered part of the route is no longer shown or visible. This results in a better clarity of the overall presentation, because further lying in the past already much earlier covered parts of the route are hidden.
  • the orientation of the user is further enhanced by this selected restriction to essential parts of the route history already traveled.
  • the reduction in the display intensity is interrupted when it is detected that the navigation system is at a standstill.
  • the detection of the standstill is arbitrary. It can be done, for example, by a detection of non-existent movement - ie a standstill - for a predeterminable period and / or by a failure of the GPS signal.
  • the length of the displayed already traveled part of the route course depends on a predeterminable time and / or on a predeterminable already traveled distance and / or on a predeterminable distance to the current position. This can be influenced by specifying certain limits the display change.
  • position data are stored continuously and comprise at least time information and / or information about the traveled distance.
  • the position data can be recorded, for example, in the form of a GPS log, wherein the information obtained from the GPS receiver geographic coordinates is also stored, which can be used later to change the representation of the already covered part of the route with respect to the spatial or temporal To adjust the distance to the current position.
  • time information and / or information about the distance traveled are available for the respective coordinates - ie the respective locations - on the part of the route already traveled.
  • the time information can be in the form of a time stamp, for example can be realized and the information about the distance traveled can be realized for example by the distance since the beginning of the route.
  • the position data further comprise information about the number of turns and / or information about the number of segments into which the already traveled part of the route is divided.
  • map matching i. an alignment of the determined position data with elements of the stored digital map is performed in order to be able to identify the affected segments (map elements).
  • map elements the change in presentation of the already covered part of the route course can also be defined on the basis of the number of turns or on the number of segments into which the part of the route already covered is subdivided.
  • the four last used roads can be displayed with decreasing display intensity, which provides a further clarity of the overall presentation.
  • the position data are stored compressed in order to save storage space.
  • This compression can be done, for example, by smoothing the waypoints to be displayed and / or by storing difference values.
  • Another exemplary way to compress or reduce the amount of data is that those position data are discarded in memory whose corresponding representation has already been hidden or their corresponding representation, as described, for example, due to the time, the distance or other criteria has been adjusted that she is no longer visible.
  • individual sections of the already traveled part of the route course are displayed as a function of the stored position data. In this case, at least one data value can be read from the stored position data for each section of the already traveled part of the route progression.
  • the representation of the respective section of the already traveled part of the route course can then be defined. It can be predetermined, for example, that a higher distance value is assigned a stronger display intensity since the beginning of the route or a later time than a smaller distance since the beginning of the route or an earlier time.
  • the different sections can also-as mentioned above-be assigned different transparencies in the color selection and / or different colors and / or different line thicknesses and / or different patterns and / or different sized position symbols and / or different gray levels.
  • FIG. 1 shows a first map representation of a navigation system from the prior art
  • 3 is a map representation of a navigation system according to an embodiment of the present invention.
  • 1 shows a first map representation of a navigation system from the prior art.
  • the user is together with the navigation system at the current position A and there has four possible routes 1, 2, 3, 4 to choose from.
  • the navigation system itself has no possibility at standstill to orientate itself with respect to the direction of the compass and the map display can therefore not be arranged at standstill.
  • the navigation system can not track the orientation of the card.
  • this known from the prior art display variant orientation problems for the user because he can not easily and quickly put the card in connection with reality.
  • the user can not see, in particular from the map display, where he came from. This already covered part of the route would be known to him but in reality and he could orientate himself to it. Without this information, it is difficult for the user to determine which of the four possible routes 1, 2, 3, 4 would be the right one.
  • FIG. 2 shows a second map representation of a navigation system from the prior art.
  • this representation in addition to the precalculated route course 1, the already traveled part of the route course 2, 3, 4 is displayed.
  • the representation of the pre-calculated route course 1 and the representation of the already covered part of the route 2, 3, 4 is identical. Furthermore, the entire covered part of the route is displayed.
  • the user has a confusing overall presentation, because firstly, he can not distinguish between precalculated route course 1 and already covered route course 2, 3, 4, secondly, no direction information from the map display and, thirdly, an identification of the route sections is made more difficult by crossing the route sections.
  • 3 shows a map representation of a navigation system according to an embodiment of the present invention.
  • the precalculated route course 1 is represented by a solid thick line and furthermore an already traveled part of the route course 2 fades, that is to say in a second representation different from the first representation.
  • the part of the route 2 already covered by the display intensity decreasing in the direction of the start position ie the fading representation, contains direction information.
  • the display intensity of the route display thus becomes stronger in the direction of movement.
