Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0022] Further design examples are explained with reference to the attached schematic drawings. They show:

[0023] FIG. 1 illustrates a sectional view through a rear-view device according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0024] A rear-view device according to the invention comprises a mirror housing 1 which is fixed to a vehicle (not shown), in which mirror housing a mirror glass 2 can be adjusted relative to the mirror housing 2 via a glass adjusting drive 3. For this purpose, two drive motors 5 can be adjusted via control electronics 4.

[0025] The drive motors 5 are used, on the one hand, in order to set the field of view for a driver or passenger of the vehicle. On the other hand, they serve to stabilize the mirror glass. A specific speed-dependent or engine speed-dependent energizing process of the two drive motors 5 can namely be used via the control electronics 4 to dampen the movement and/or vibration of the mirror glass 2 perceived by eye during the driving process of the vehicle, without adjusting the field of view. More precisely, the energizing process of the two drive motors 5 can be carried out by current pulses with frequency-dependent pole reversal or by means of a permanent current which is limited in terms of its current intensity such that the set field of view is not adjusted, but a mirror image which is free of vibrations for the human eye is produced on the mirror glass 2.

[0026] At least one advantage of the invention is therefore that an active damping of the mirror glass 2 can be achieved with active components which already exist in the glass adjusting drive 3 and that no additional active or passive components have to be mounted in any way on mirror components.

[0027] The features of the invention disclosed in the preceding description, the claims and drawing can be essential, both individually and in any combination, for realizing the invention in its various embodiments.
