However, there is no link to this turn in the map display to warn in advance
If, for example, there is a gentle, non-emergency left turn ahead of the vehicle, followed by an urgent right turn, it occurs that the right turn symbol is seen on the display before the left turn. This arrangement is very important for the user is not clear

Embodiment Construction

[0026] In the following description of preferred exemplary embodiments of the present invention, identical or similar reference symbols are used for similarly acting elements shown in different figures, a repeated description of these elements being omitted.

[0027] Figures 1 to 8 The representation of turns in an electronic street map according to various exemplary embodiments of the present invention is shown in each case. This display can be realized on a display screen, for example a display screen of a navigation device.

[0028] figure 1 A display of the planned driving route 102 with the current position of the vehicle 103 is shown. As a result, the vehicle 103 can travel along the planned travel route 102 on the road. Warning indication 104 warns of an urgent turn on planned driving route 102 . Warning indication 104 can be placed within or before the emergency curve. As a result, vehicle 103 moves toward the sharp turn.

[0029] According to this exemplary em...

Abstract

The invention provides a method of displaying a curve trend on a display device (928) of a driver information system. The method involves determining curve lies on a planned driving route (102) based on a digital road map base (924), dividing the curve into critical curves and into less critical curves according to classification rules and obtaining whether a curve trend of at least two successive critical curves exists. A display information (930) is determined for graphical representation of the critical curve progression on a display device (928).

Description

technical field [0001] The invention relates to a method for displaying a curve course on a display device of a driver information system, to a corresponding driver information system, and to a corresponding computer program product. Background technique [0002] Modern driver assistance systems provide a corner warning signal, which outputs an audible reminder of an emergency corner and displays, for example, a warning indication on a display. However, lack of association with this turn in the map display, no advance warning. If, for example, there is a gentle, non-emergency left turn ahead of the vehicle, followed by an urgent right turn, it occurs that the right turn symbol is seen on the display before the left turn. This arrangement is very important for the user is unclear. [0003] DE 102 55 331 A1 relates to an information system for informing the driver of a vehicle of the properties of sections of a travel route which lie in the direction of travel ahead of the v...
