Abstract

Claims (36)

1 . A vehicle device for a vehicle, said vehicle device comprising:

a body component and a control device,

wherein the body component comprises a fiber device, wherein the fiber device comprises fibers and is electrically connected to the control device,

wherein the fiber device is configured to convert a deformation of the body component into electrical energy, and

wherein the control device is configured to apply a first voltage to at least a portion of the fibers in order to effect a change in a stiffness of the fibers,

wherein the fibers of the fiber device run upwards and obliquely along the body component and the fiber device.

2 . The vehicle device according to claim 1 , wherein the fiber device is configured to generate the electrical energy by a piezo effect or by a triboelectric effect.

3 . The vehicle device according to claim 1 , wherein the control device is configured to generate, by the first voltage, a current through the fibers in order to cause the change of the stiffness of the fibers.

4 . The vehicle device according to claim 1 , wherein the control device is configured to receive a first signal, wherein the first signal carries a first information about a movement of the vehicle, and wherein the control device is configured to influence the first voltage as a function of the first signal.

5 . The vehicle device according to claim 1 , further comprising a data memory associated with the control device, wherein the data memory has stored at least a first data value comprising information about a vibration behavior of the body component, and wherein the control device is configured to output the first voltage as a function of the first data value.

6 . The vehicle device according to claim 1 , wherein the fibers are attached to the body component by at least one connection element from a connection element group consisting of:

lamination,

adhesion, and

foliation.

7 . The vehicle device according to claim 1 , wherein the body component is configured to form an outer skin of the vehicle.

8 . The vehicle device according to claim 1 , wherein the fibers comprise piezoelectric material, wherein the piezoelectric material enables voltage generation as a function of the deformation of the body component and a change in the stiffness as a function of a current.

9 . The vehicle device according to claim 1 , wherein the fibers comprise at least one type of fiber from a fiber type group consisting of:

carbon fibers,

fiberglass, and

plastic fibers.

10 . A vehicle comprising the vehicle device according to claim 1 .

11 . The vehicle according to claim 10 , wherein the body component has a predetermined position in the vehicle.

12 . The vehicle device according to claim 1 , wherein the fibers run upwards and obliquely along the body component and the fiber device at a first angle from a horizontal, wherein the first angle is within a range of 20° to 70°.

13 . The vehicle device according to claim 1 , wherein the fibers run upwards and obliquely along the body component and the fiber device at a first angle from a horizontal, wherein the first angle is within a range of 30° to 60°.

14 . The vehicle device according to claim 1 , wherein the fibers run upwards and obliquely along the body component and the fiber device at a first angle from a horizontal, wherein the first angle is within a range of 40° to 50°.

15 . A vehicle device for a vehicle, said vehicle device comprising:

a body component, a control device and a movement sensor disposed on the body component,

wherein the body component comprises a fiber device, wherein the fiber device comprises fibers and is electrically connected to the control device,

wherein the fiber device is configured to convert a deformation of the body component into electrical energy,

wherein the control device is configured to apply a first voltage to at least a portion of the fibers in order to effect a change in a stiffness of the fibers,

wherein the control device is configured to receive a first signal, wherein the first signal carries a first information about a movement of the vehicle,

wherein the control device is configured to influence the first voltage as a function of the first signal,

wherein the movement sensor is configured to generate a second signal as a function of a movement of the body component and transmit the second signal to the control device, and

wherein the control device is configured to output the first voltage as a function of the second signal in order to reduce the movement of the body component.

16 . The vehicle device according to claim 15 , wherein the control device is configured to output the first voltage as a function of the second signal in order to reduce a vibration of the body component.

17 . The vehicle device according to claim 15 , wherein the fiber device is configured to output a third signal to the control device as a function of the generated energy, and wherein the control device is configured to generate the first voltage as a function of the third signal.
