Abstract: A method for determining the mass of a motor vehicle while taking different driving situations into consideration, involving an evaluation of a vehicle acceleration, wherein apart from a driving force of a vehicle drive unit, resistance forces resulting from rotational forces, air resistance, rolling resistance, the slope descending force and a braking force are taken into consideration. Additionally, a multitude of different driving situations may be evaluated, wherein the individual results are stored and combined suitably into a collective mass value. Further, different driving situations can be weighted differently in determining the mass value.

Abstract: The invention relates to a method for determining the mass of a motor vehicle while taking different driving situations into consideration, involving an evaluation of the respective vehicle acceleration, wherein apart from the driving force of a vehicle drive unit the respective resistance forces resulting from rotational forces, from the air resistance, from the rolling resistance and the slope descending force, are taken into consideration and wherein in the same approach additionally the respective braking force is taken into consideration so that a multitude of different driving situations is evaluated, wherein the individual results are stored and combined suitably into a collective mass value. Hereby different driving situations can be weighted differently.

Abstract: Assembly mounts are stochastically or periodically detuned by changing their spring rate in order to prevent the transient effect of stuttering vibration of the drive assembly of a motor vehicle. The adjustment of the spring rate by at least a factor of 5 takes place for a time period which corresponds to no more than one fifth of the vibration duration of the stuttering movement.
