Embodiment Construction

[0021] figure 1 The damping system 10 is shown schematically. The damping system 10 includes a damping mount 12 having a first bearing element 14 and a second bearing element 16 . The first bearing element 14 and the second bearing element 16 are connected to each other via an active adjustment element 18 .

[0022] The active adjusting element 18 can be controlled by a control unit 20 , to which the active adjusting element is connected for this purpose.

[0023] Furthermore, at least one acceleration sensor 22 , 24 is respectively arranged on the first support element 14 and the second support element 16 for measuring the vertical acceleration of the corresponding support element.

[0024] Such as figure 1 As shown, the first carrier element 14 is connected to the top of the spring strut, ie to the body structure. Acceleration sensor 22 assigned to first bearing element 14 therefore measures the acceleration of the body structure in this region.

[0025] The second bear...

Abstract

The invention relates to an active damper system (10) for damping high-frequency vibration excitation of the vehicle structure, wherein a damper bearing (12) for supporting a chassis component is provided on the vehicle structure, and the damper bearing (12) comprises a first bearing element (14) to be fastened to the vehicle structure and a second bearing element (16) to be fastened to the chassis component, and an active actuating element (18) is also provided, wherein a regulator unit (20) and an acceleration sensor (22) which measures the acceleration of the vehicle structure are provided, wherein the vertical acceleration of the vehicle structure (aD) is the input variable to the regulator unit (20), to which end the regulator unit (20) is connected to the acceleration sensor (22), and the active actuating element (18) is also influenced by the regulator unit (20). The invention is distinguished in that the first bearing element (14) and the second bearing element (16) are connected by means of the active actuating element (18) and, in addition, an acceleration sensor (24) is arranged on the second bearing element (16).

Description

technical field [0001] The invention relates to an active damping system for damping high-frequency vibrations of a vehicle body structure. Background technique [0002] It is known from the prior art (as described in DE 10 2008 046 876 A1) to achieve an optimization of the vibrations between the wheel and the vehicle body by means of a passive damping system, for example using a spring strut of piston-cylinder construction Control to achieve vibration damping of the body structure. [0003] According to DE 10 2008 046 876 A1, the damping of vibrations can be determined by adjusting the damping force. The damping force is realized by the actuation control device while detecting the vertical acceleration of the body structure and the vertical acceleration of the wheels. A control signal is generated by means of a signal processing device for the regulation of the control device of the dual-modular damping force. [0004] The disadvantage of this method is that the entire s...
