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: An overlay steering system for a vehicle includes a mechanical steering apparatus for the transfer of a steering torsional moment at a predetermined transfer ratio to at least one steered wheel, a wheel angle sensor connected to at least one steered wheel for generating a wheel angle signal corresponding to an angle of the at least one steered wheel, a comparison device for comparing the steering angle signal and the wheel angle signal as well as for generating a comparison signal based on the steering angle and the wheel angle, and an electromechanical converter for generating the overlay torsional moment, if the comparison signal indicates the presence of a deviation from the predetermined relation between the steering angle and the wheel angle of the at least one steered wheel, resulting in a reduction of the deviation.

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: A suspension for a vehicle includes a displacer which can be actuated by the relative motions between a vehicle wheel and the vehicle body. The displacer includes a working space or chamber containing a flow medium connected by at least one throttle to one of at least two springs which can be loaded by the flow medium. The two springs have different load-dependent spring rate changes whereby the distribution of the volume proportions of flow medium displaced to the springs differs depending on the static flow medium pressure. At least one throttle which operates as a function of load is placed in front of the less progressive spring.

Abstract: An individual wheel suspension for a non-steered wheel of a motor vehicle such as an automobile comprises a trailing arm including a lengthwise arm directed along the length of the vehicle, the trailing arm being articulated to the vehicle body by means of the lengthwise arm as well as two wishbones which are arranged transversely to the length of the vehicle and are located one above the other wherein at least the articulation of the lengthwise arm is an elastic bearing.
