1. A method for displaying navigational information for a first vehicle to a driver of the first vehicle, comprising the steps of:
- displaying navigational information for the first vehicle in the form of a virtual pilot vehicle superimposed on an image of the vehicle environment of the first vehicle;
determining a position, an orientation and a size of the displayed virtual pilot vehicle based on a current speed of the first vehicle, reference points for a recommended route, a position and orientation of the first vehicle, a position and orientation of a camera for recording the first vehicle environment and an eye position and a line of sight of the driver, andusing the virtual pilot vehicle to display a route or action recommendation indicating to “
keep minimum distance from the vehicle ahead in accordance with the current driving speed”
by positioning the virtual pilot vehicle on the image of the vehicle environment such that the virtual pilot vehicle appears to be proceeding in front of the driver at precisely the minimum distance currently required, while driving too close to a second vehicle in front of the first vehicle is shown by the second vehicle being located in the image between the driver and the virtual pilot vehicle.

5. A device for displaying navigational information for a first vehicle to a driver of the first vehicle, comprising an apparatus for superimposing navigational information for the first vehicle in the form of a virtual pilot vehicle on an image of the vehicle environment of the first vehicle such that a position, an orientation and a size of the virtual pilot vehicle are determined in accordance with a current speed of the first vehicle, reference points for a recommended route, a position of the first vehicle, an orientation of the first vehicle, a position of the camera for recording the vehicle environment and an orientation of the camera for recording the vehicle environment, wherein a route or action recommendation to “
- keep minimum distance from the vehicle ahead in accordance with the current driving speed”
is displayable by positioning the virtual pilot vehicle on the image of the vehicle environment such that the virtual pilot vehicle appears to be proceeding in front of the driver at precisely the minimum distance currently required, while driving too close to a second vehicle in front of the first vehicle is indicated when the second vehicle is located in the image between the driver and the virtual pilot vehicle.
- keep minimum distance from the vehicle ahead in accordance with the current driving speed”
