A method and an apparatus for determining current orientation data for a vehicle (3) relative to a world coordinate system are described. These first of all involve a reference object (21, 25, 29), which typically has a prescribed orientation (23, 27, 31) relative to the world coordinate system, being recognized by means of an object recognition system that is fitted in the vehicle (3), for example with a video sensor system (5, 7, 9). Next, the orientation (23, 27, 31) of the reference object (21, 25, 29) relative to a current orientation of the object recognition system (2) and hence relative to a current orientation (19) of the vehicle is determined. Finally, current vehicle-specific orientation data relative to the ascertained orientation (23, 27, 31) of the reference object (21, 25, 29) and hence relative to a world coordinate system can be ascertained therefrom. These orientation data can be used by vehicle functions, such as a braking assistant or the controller of an active chassis, to customize modes of action on the basis of an absolute orientation (19) of the vehicle (3) or a relative orientation of the vehicle (3) to an orientation (17) of the carriageway. |
