Method and device for displaying driving instructions, especially in car navigation systems
First Claim
1. A method for displaying driving instructions, wherein the surroundings of a vehicle are recorded in a field of vision of a driver by a vehicle camera and augmented by driving instructions on a navigation display unit as a function of a destination and current position of the vehicle, comprising:
- determining a current geographical position of the vehicle camera in three dimensions, a current orientation of the vehicle camera being determined in a horizontal plane and a current angle of inclination of the camera viewing direction relative to the horizontal being determined;
deriving a particular position of a navigation point from a three-dimensional map to generate driving instructions;
calculating at least one viewing angle in a vertical dimension, at which the navigation point is viewed from the vehicle camera as a function of the current angle of inclination; and
adjusting display of the driving instructions as a function of the at least one viewing angle at least in the vertical dimension on the navigation display unit.

Abstract
A method and device is for displaying driving instructions. The aim is to achieve a better consistency between the image recorded of the surrounding terrain by the vehicle camera and presented in the driver'"'"'s field of vision, and the keyed-in calculated driving instruction. For this purpose, the inclination of the vehicle about its longitudinal axis and lateral axis relative to the road surface as well as the incline of the road or the three-dimensionality of the terrain are taken into consideration when a keyed-in driving instruction from the angle of view of the driver is produced.

6. A method for displaying driving instructions, comprising:
-
determining a current geographical position of at least one eye of a driver, in three dimensions, using a tracking system, wherein a current position of the vehicle and a current angle of inclination of a longitudinal axis of the vehicle relative to a horizontal are determined in order to establish the current field of vision of the driver;
deriving a particular position of a navigation point as a function of a destination from a three-dimensional map to generate driving instructions;
calculating at least one viewing angle in a vertical dimension, at which the navigation point is viewed from at least one eye of the driver, based on the current angle of inclination; and
adjusting display of the driving instructions to the relative field of vision of the driver as a function of the viewing angle at least in the vertical dimension. - View Dependent Claims (15, 16, 17)
