Method for Determining a Predictive Ego Speed of a Vehicle Traveling along a Predetermined Route, Control Device for a Vehicle or for a Navigation Device or for a Mobile User Terminal, Navigation Device and Vehicle

The present disclosure relates to a method for determining a predictive ego speed of a vehicle traveling along a predetermined route for at least one location or at least one section of the route, by determining an average speed currently traveled by road users at the location or the section, determining a first average speed which is so low that it is to be assumed that the ego speed of the vehicle, at this location or this section, corresponds to the average speed of traffic density, determining a second average speed that is so high that it is to be assumed that the traffic density at this location or this section does not influence the ego speed of the vehicle, if the average speed is between the first average speed and the second average speed, determining the predictive ego speed on the basis of the average speed and by means of an interpolation between the first average speed and the second average speed.
