  • the optimum display mode for the current driving situation or the position of the motor vehicle can always be set automatically. For example, if the motor vehicle is on a highway, which also has to follow for a longer distance, the driver generally does not need any specific driving instructions for a longer time. In addition, the traffic situation is then usually relatively well manageable. On the display unit can then be done, for example, a map display with guidance guidance information, so that a rough orientation on the progress of the drive is possible. The route guidance device is thus in the first display mode.

If the driver now looks at the display unit, which is in the second display mode, for orientation via the further route or the next driving maneuver, he finds there a real image of the detected local environment to which the route guidance information is superimposed. In the real image of the detected local environment, the driver can then also, for example, suddenly on the roadway pedestrians recognize and respond in a timely manner. With the route guidance device according to the invention an increase in driving safety is thus achieved in different driving situations.

Furthermore, due to the recognized roads, a road branching ahead may also be detected. In particular, a switching between the first and the second display mode can then also take place on the basis of the recognized roads. This has the advantage that recourse to map data is not required. This is advantageous, for example, if the route guidance device does not have such detailed map data, but the route is determined only on the basis of a few turn-off points.
