Abstract: A system is provided for determining a volume of material milled, or a surface area milled, by a construction machine having a milling drum. The volume of material milled is determined as a function of a cross-sectional area of material to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling. The cross-sectional area is determined in part by direct machine observation of one or more profile characteristics of a ground surface in front of the milling drum. The surface area milled is determined as a function of the width of the area to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling.

Abstract: An identification key associated with a motor vehicle is carried by a user as the user moves outside of the motor vehicle. When the identification key enters the reception range of short-range transceiver units, position data of the identification key are ascertained and transmitted via a far-field transceiver unit which is not included in the identification key. The receiver of the transmitted position data ascertains a movement vector for the identification key from the position data. If the movement vector meets at least one predefinable activation criterion, preconditioning of at least one component of the motor vehicle is activated.

Abstract: A bearing system, for bearing a motor vehicle assembly at a motor vehicle body, with a fluid operating chamber that is in flow connection, by way of at least one fluid channel, with a fluid equilibration chamber, which is present in a housing of the bearing system. The fluid operating chamber and the fluid equilibration chamber are separated by a separating element, in which the at least one fluid channel is present. The separating element is decoupled from the housing by an elastic element, which surrounds the separating element in the peripheral direction. The housing has a cover, which accommodates the fluid equilibration chamber, and a supporting part, which holds a spring element of the bearing system.

Abstract: An assembly bearing arrangement for a motor vehicle includes an assembly bearing having a bearing housing, a vibration-damping bearing, and a bearing core connectable to a power train element. The bearing housing is connected with a body-fixed carrier part by a first fastening element, oriented in a direction that differs from a vertical direction, in a torsion-resistant manner, and by a second fastening element, oriented substantially in the vertical axis direction. A U-shaped stop bracket bridges the bearing core and is firmly connected to the bearing housing. The bearing core is formed with diametrically opposite stop arms, which in basic position are spaced from legs of the stop bracket by a gap distance. A first stop buffer is arranged on inner surfaces of the stop bracket and/or the bearing core, and second stop buffers are arranged on the legs of the stop bracket and/or the stop arms between the legs and the stop arms.

The bearing housing is connected with a body-fixed carrier part by a first fastening element, oriented not in vertical axis direction (Z-direction), in a torsion-resistant manner, and by a second fastening element, oriented substantially in the vertical axis direction. A U-shaped stop bracket bridges the bearing core and is firmly connected to the bearing housing. The bearing core is formed with diametrically opposite stop arms, which in basic position are spaced from legs of the stop bracket by a gap distance.

Abstract: Axially damping hydraulic mount is provided, relating to elastomer mounts for engine mounts for damping the vibrations transmitted from internal combustion engine to the body and for acoustic decoupling. The hydraulic mount includes a frustoconical elastomer support spring, between mount core and upper part of outer jacket, with a working chamber and a compensating chamber for fluid damping medium. Chambers are separated from one another by a separator extending transversely to the mount axis and includes a coupling diaphragm, wherein the working chamber is enclosed by support spring and separating element. Compensating chamber is enclosed by separating element and elastomer bellows. A duct on the separating element is enclosed by a duct part. To counteract excessive increase in dynamic spring rate when frequencies of axially acting vibrations are present, the duct part is occupied by an additional mass. Then the duct part is rigidly connected to a mass element.
