Embodiment Construction

[0046] The following examples are given as examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference 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.

[0047] In the following description, reference is made to the first guide member and the second guide member. This involves simple indexes used to distinguish and name similar but not identical elements. This index does not imply the preference of one element over another, and the designations could easily be interchanged without departing from the scope of the invention. Nor does this indexing imply a chronological sequence, eg to evaluate the movement of supports.

[0048] refer to figure 1 and 2 , the invention relates to a driver assistance system 1 comprising an optical sensor 11 for a motor vehicle and a pr...

Abstract

The invention relates to a driver assistance system (1) comprising a device (2) for protecting an optical sensor (11) for a motor vehicle comprising a protective box (13) in which a housing (26) is provided that is configured to house an optical sensor (11), the device further comprising: a support (15) movably mounted on the protective box (13) and bearing a membrane (19) attached by its periphery to the support (15) and intended to be arranged opposite the optical sensor (11), the membrane (19) comprising an optically transparent material that is elastically deformable; and at least one actuator (21) borne by the protective box (13) and configured to move the support (15) bearing the membrane. The support (15), under the effect of the moving of the support (15) by the actuator (21), is configured to deform the membrane (19) between a resting position in which the membrane (19) is in a first state of tension and an active position in which the membrane (19) is in a second state of tension.

Description

technical field [0001] The present invention relates to the field of driving assistance, in particular to a driving assistance system installed on a particular vehicle, which can include an optical sensor, such as a camera including a lens. More specifically, the invention relates to a protection device for such a driver assistance system, comprising means for cleaning its optical components. Background technique [0002] Currently, a large number of motor vehicles are equipped with front-view, rear-view or even side-view cameras. In particular they form part of driver assistance systems, such as parking assistance systems or even lane departure detection systems. [0003] Cameras are installed inside motor vehicles to assist with parking. These cameras are well protected from random climatic factors such as dirt associated with organic or mineral pollutants. However, especially for parking assistance, the viewing angle of such cameras installed in the interior is not opt...
