Zusammenfassung: | The invention relates to a method (1) for estimating a true ground speed (VRef) of an electrically drivable land vehicle by method of the vehicle's own evaluation electronics. In order to improve the estimation of the true speed (VRef), in particular in limit situations with restricted vehicle handling, a first speed value (V1) is determined taking into account an instantaneous wheel speed of at least one vehicle wheel of the land vehicle, a second speed value (V2) is determined taking into account a longitudinal acceleration of the land vehicle, a third speed value (V3) is determined taking into account received GPS data and a fourth speed value (V4) is determined taking into account camera data from a camera of the land vehicle, the true speed (VRef) being estimated taking into account these speed values (V1 to V4). |
