Problems solved by technology
As a result, the quality and field of view of the image taken by the optical sensor suffers
Finally, the use of this protection system does not allow wide viewing angles, since the optical sensor is arranged inside the housing that supports the cover without making this housing a protrusion

Embodiment Construction
[0048] In these figures, the same elements have the same reference numerals.
[0049] The following examples are given as examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference numeral refers to the same embodiment, or that a feature is only applicable to a single embodiment. Single features of different embodiments may also be combined or interchanged to provide other embodiments.
[0050]In the description, certain elements may be numbered, such as a first element or a second element. In this case, it is a simple number used to distinguish and name close but not identical elements. This numbering does not imply the priority of one element over another, and the designations may be readily interchanged without departing from the scope of the invention. Nor does this numbering imply chronological order.

Abstract
The invention relates to a protective device (3) for protecting an optical sensor (13) of a motor vehicle. According to the invention, the protection device (3) comprises: a transparent optical element (9) mounted rotatably movable around the axis of rotation (A1), said optical element (9) being configured to be arranged in the optical upstream of the unit (14), so that the axis of rotation (A1) of said optical element (9) coincides with the optical axis (15) of the optical sensor (13); The rotation shaft is configured to rotate around an axis of rotation (A2), and the motor (5) is configured to rotate the optical element (9) such that the axis of rotation (A1) of the optical element (9) is also aligned with the motor The rotation axes (A2) of the rotation shafts (51) of (5) coincide. The invention also relates to a corresponding driver assistance system (1) and a cleaning method for realizing such a protective device (3).
Description
technical field [0001] The present invention relates to the field of driver assistance, in particular to driver assistance systems installed on certain motor vehicles, which can include optical sensors, such as video cameras including lenses. More specifically, the invention relates to a device for protecting such an optical sensor. The invention also relates to a method for cleaning the optical elements of such a protective device. Background technique [0002] Currently, a large number of motor vehicles are equipped with front-view, rear-view or side-view cameras. They form in particular part of a driver assistance system, for example a parking assistant or a lane departure detection system. [0003] The camera is known to be mounted in the passenger compartment of the vehicle, against the rear window / windscreen, looking backward through the rear window of the vehicle. These cameras are well protected against external climatic changes and contamination by organic or min...
