Device for protecting an optical sensor and driver assistance system comprising an optical sensor

Abstract

The invention concerns 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.
