Definitions

  • the invention relates to a method for displaying a weather event and a corresponding display system.
  • the objects are uniquely mapped to the nodes of the grid.
  • the nodes of the grid is uniquely assigned a code by a second reversible calculation rule.
  • a method for generating route-related weather and / or road condition information for a vehicle is known.
  • the weather forecast data and data relating to the actual weather-related conditions in the surroundings of the motor vehicle are recorded by a central unit and informed on a display in the field of vision of the driver about the actual weather or the road condition along the travel route.
  • the display of weather information on screens using a browser is known.
  • An image is prepared by a service provider by providing it with a geographical reference (usually outline of the land mass with representation of national borders) and is brought into a digitally processable image format (GIF, JPEG, TIFF), which is then transmitted via communication media and displayed with the help of a browser.
  • the invention is therefore based on the object of specifying a technical teaching with which, in particular, the driver of a motor vehicle can be comprehensively and easily informed about location-dependent weather events.
  • a part of a road map is displayed on a display device based on a vector-oriented electronic road map.
  • a weather event object is received that includes a weather code, a surface description object, and reference coordinates.
  • the area description object may describe the size, orientation, and / or shape of the area by, for example, indicating coordinates of further corners or edge points of a geometric shape, or by specifying vectors that describe a geometric shape or traverse based on the reference coordinates.
  • the weather event is then displayed on the display device based on the weather event object as a surface superimposed on the illustrated road map, in particular transparent or semitransparent.
  • size information contained in the area description object is still adapted to the currently set zoom factor of the representation of the road map in order to reliably inform the driver also with regard to the size of a current or predicted weather event.
  • the vector-oriented electronic road map is based on nodes or edges or is described thereby, wherein the nodes are each assigned the coordinates of a defined coordinate system. Since the reference coordinates can also be described or described by coordinates of the defined coordinate system (if necessary after a corresponding conversion), the areal weather forecast can be described or described. Position can be assigned to the correct location or the correct node of the road map and so in relation to the road map displayed in the right place.
  • the location of the area relative to the road map is determined based on at least one node of the road map and the reference coordinates, for example by assigning the reference coordinates to the node closest to the coordinate system or by locating the reference coordinates relative to two nearby nodes of the road map is determined by interpolation or extrapolation.
  • a display system having a display device for displaying at least a part of a road map based on a vector-oriented electronic road map, with a receiving device for receiving a weather event object comprising a weather code, a surface description object and reference coordinates, and with a processor device , which is set up such that, based on the weather event object, the weather event is displayed on the display device as the area superimposed on the road map shown.
  • FIG. 1 shows a simplified flow diagram for the representation of a
  • FIG. 2 shows a representation of a two-dimensional weather event
  • FIGS. 3-6 show variants for describing a two-dimensional weather event.
  • weather information is summarized based on corresponding measurements and provided in a suitable form:
  • a) Weather data in GRID format (gridded binary), which includes georeferencing.
  • Precipitation zones based on a weather radar which have a (karto) graphical and local reference (coordinates of the radar station).
  • these weather information are processed in such a way that they can be displayed by a navigation system in the correct location.
  • a planar weather event is converted into one or more weather event objects, each comprising a weather code, a surface description object and reference coordinates (for example, a reference coordinate pair, which may also be referred to as a reference coordinate) in WGS84 coordinates.
  • weather event objects each comprising a weather code, a surface description object and reference coordinates (for example, a reference coordinate pair, which may also be referred to as a reference coordinate) in WGS84 coordinates.
  • the area description object indicates the size, orientation, and / or shape of an area within which the corresponding weather event occurs.
  • the surface can be defined by WGS-84 coordinates of other corners or boundary points of a geometric shape or by vectors (described ben by suitable WGS-84 coordinates), which describe a geometric shape or a polygon starting from the reference coordinates.
  • WGS-84 coordinates which describe a geometric shape or a polygon starting from the reference coordinates.
  • the area description object is likewise described vector-oriented.
  • the weather event object is transmitted, for example, in the context of a broadcast, multicast or unicast system to one or more vehicles, in particular vehicle navigation systems F, and stored there in a memory device.
  • a vector-oriented digital road map is stored, which can be displayed in sections with different scales on a display device.
  • vector-oriented means that the electronic road map is based on nodes and edges, wherein the nodes are each defined by WGS84 coordinates.
  • lines or curves are defined by a starting point, possibly several intermediate points and an end point, and the line thickness. The link or edge between these points is then calculated by a graphics program and gives, for example, a road to be displayed. In areas next to the line also the type of filling is defined.
  • a vector graphic can be scaled down or enlarged without loss of quality.
  • the weather event is displayed as the superimposed surface of the road map shown.
  • the location of the area is determined based on the road map based on at least one node of the road map and the reference coordinate.
  • the size and shape of the Area determined by the location of the remaining vertices transmitted with the area description object.
  • the position of these corner points relative to the road map is likewise determined based on at least one node of the road map and the corresponding coordinates of the corner point.
  • the surface is anchored on the vector-oriented road map or the road map läge- and size correctly assigned, so that the representation of the area together with the representation of the road map is freely scalable and displayed accordingly.
  • FIG 2 shows the representation of a road map SK with a superimposed representation of two different weather events ("rain”, “heavy rain”) with corresponding vertices (numbers 1 to 10 and 1 to 9).
  • the weather event WE “rain” is represented by a larger area, which is superimposed on the road map representation substantially transparent.
  • the reference coordinates RK of this area are also shown.
  • the weather event "Heavy Rain” is represented by a smaller area, which is essentially not transparently superimposed on the road map display.
  • FIG. 3 shows a rectangle which, starting from the reference coordinates RK, is spanned by two vectors of length a and b.
  • One or more such rectangles may describe the area of a weather event.
  • FIG. 4 shows an ellipse which, starting from the reference coordinates, is determined by two vectors of length a and b.
  • One or more of such ellipses may also describe the area of a weather event.
  • Figure 5 shows a plurality of tiles of the same size, shape and orientation, by starting from the reference coordinates by the indication Further coordinate pairs (0.0, 0.1, 1, -1, ...) the surface of a weather event can be described.
  • FIG. 6 shows, starting from the reference coordinates, a polygon whose vertices can each be described by a vector. By such a polygon, the area of a weather event can also be described.
