Definitions
- the invention is based on a method for map display and a driver information system with a map display according to the preamble of the independent claims.
- Such methods and driver information systems are known, for example, from DE 199 26 367 A1 and US Pat. No. 6,151,552. These indicate vehicle navigation systems, in each case a map section is displayed on a display, the scale of the
- Map display is reduced when approaching an intersection.
- the scale of the map display is always set as small as possible and continuously adapted so that a current vehicle position and a so-called decision point, ie a junction, intersection or the like, to which a driving direction hint for route guidance relates, together on the Display are shown. As the vehicle position approaches, the intersection is thus shown to be increasingly larger so that orientation is facilitated for the driver.
- US Pat. No. 6,151,552 also teaches that the next branch to which a driving instruction relates in the context of the route guidance is displayed on the display of the vehicle navigation system as far as possible in the format of a full frame, the magnification However, this is limited by the fact that the intersection is shown completely, so not just a section of the intersection on the display.
- the road to be traveled after the intersection instead of exactly straight in reality is half left or half right, allows a
- a branch lying on the currently traveled track is then also selected for an enlarged display (crossing zoom) if no direction indication is output for this as part of a route guidance.
- a branch can also be selected for an enlarged representation if a route guidance is deactivated.
- Branches that meet certain criteria may be limited to branches to high-level traffic routes. If, for example, a driving route leads through a city through a city, then preferably only such branches would be selected for an intersection zoom, which would turn onto one or more further urban thoroughfares or otherwise
- Main roads allow, but not, for example, branching dead-end streets with residential character. Also, the crossing zoom representation may be limited to larger intersections in the absence of guidance guidance.
- the display scale and the map section to be displayed for the crossing zoom display are selected so that the entire branching can be displayed on the display area.
- the currently traveled roadway and / or a driving route is highlighted in the map section shown on the display.
- FIG. 1 is a block diagram of a driver information system according to the invention for
- FIG. 2 is a flowchart of the method according to the invention. - A -
- FIGS 3 and 4 displayed on the display of the driver information system map excerpts.
- the driver information system 1 is preferably a known vehicle navigation system. This includes in a conventional manner, a central controller 10, the further locating means, such as a
- Satellite positioning signal receiver 11 such as GPS or Galileo system signals and digital road map 12, for example in the form of map data stored in a mass storage such as CD-ROM, DVD, hard disk, RAM or the like.
- the navigation system 1 comprises a display 13, for example in the form of a liquid crystal display (LC display) for displaying a
- the process begins with a route calculation known per se from a start or current vehicle location determined by the location means 11 to a navigation destination in the central control 10 entered by the user via input means, using a route calculation algorithm, for example, to Ford Moore and the digital road map 12 (Step 100).
- a route calculation algorithm for example, to Ford Moore and the digital road map 12
- Route calculation the travel route, drawn in a road map, displayed on the display 13 of the navigation system 1 (step 110).
- the current vehicle position is continuously determined (step 120).
- the location information of the location means 11 in the controller 10 is preferably made plausible in a manner known per se with the digital road map 12, which is also known as "map matching.”
- the resulting vehicle position 21 is drawn on the display 13 in the map display.
- the check is made by adjusting the current vehicle position with the map data 12 in step 130 - is switched to an intersection zoom representation of this branch (steps 140 and 150).
- Branching is understood to be a branch, intersection, junction and the like, on which it is possible to continue on from the current vehicle location from one of several, but at least two, possible routes, and therefore also allows a deviation from the calculated travel route.
- intersection zoom is meant that the representation scale of the map representation is adjusted so that the branch is displayed on a reduced scale on the display 13, that is, the representation scale of the branch and the branch containing map section are chosen such that the longitudinal - And / or transverse extent of the branch at least a predetermined proportion of the display height and / or width fills.
- the branch is displayed on the display 13 at least in an expansion direction between 1 A of the display size and full-format filling.
- Crossing zoom display is done in step 140, the representation of the map section with the set parameters in step 150.
- step 160 scale and map section for a
- the switchover of the map display from the overview map to the crossing zoom therefore takes place independently of whether or not route guidance information about the branch concerned is output. That is, it is switched to an intersection zoom display both when approaching a branch to which a drive advice is issued and a branch to which no drive notice is output.
- the switching to crossing zoom display can also be provided if the route guidance is deactivated.
- the representation of the overview map is switched over again from the crossing zoom representation (step 130).
- the sequence is repeated when approaching the vehicle position to another
- FIG. 13 shows a map section on which an intersection 20, which consists of a first track 25 leading from bottom to top left, one of them branches off to the top right second track 26 and a right branching third track 27.
- Map Au coupons additionally the vehicle position 21 is displayed.
- the calculated driving route 23 is preferably drawn alternatively or additionally in the form of a colored marking or the like, which here follows the second travel path 26 branching off to the top right.
- Switching from the display of the overview map to a crossing zoom is not limited to decision points.
- Decision point is understood as a branch to which the vehicle navigation system outputs a driving instruction to the user in the form of a display or a voice output for guidance along the calculated route. Rather, it is erfmdungshunt provided that is switched to an intersection zoom display at other branches, to which the navigation system does not output driving instructions, for example, because an intersection is to be traversed in approximately straight direction. Situations in which such a crossing zoom presentation, for example, facilitate the orientation of the driver
- the route runs from a turning right-of-way into a straight-ahead secondary road.
- no driving instruction is issued as the route continues leads straight ahead.
- the route runs, as shown in Figure 1, over a junction 20 away in a half-right kinking road 26, but there is also a schblinks kinking, continuing road 25.
- the half right kinking road 26 is noted as a straight ahead road, while the half left road 25 is interpreted as a left turning road.
- the crossing zoom display can advantageously also take place when the route guidance is not activated. Then, no calculated route 23 is displayed, but the vehicle location 21 and according to the advantageous embodiment described here also the currently traveled route 22.
- Representation is preferably determined a center of the entire branch concerned and the map selected so that its center coincides at least approximately with that of the branch. Subsequently, the scale is set so that the entire branch can be displayed on the display surface. This is shown in FIG. 3 using the example of a motorway junction in so-called "cloverleaf
- intersection zoom map display is also applicable to non-permanent map display, so if the navigation system does not output an overview map or the like on the display.
- an intersection zoom map is displayed only when approaching intersections and junctions. It is shown only at intersections and branches, for example, in addition to a per se known arrow representation, a map section on a display section next to the arrow display display in a suitable autozoom scale, which includes the whole branch. After passing the intersection or branch when the vehicle location is no longer in the area of the branch, the map display is switched off.
- intersection zoom representation with the representation of an overview map in such a way that the intersection zoom representation is superimposed, for example, in a corner of the overview map or this is superimposed. In this case, the larger part of the display area will continue to display the overview map and the intersection zoom
- intersection zoom representation occupies, for example, the largest part of the ad space and the overview map only a smaller part of the ad area or that the overview map on an enlarged scale in one corner of the intersection zoom map is superimposed or overlaid.
