  "textContent": "The present invention relates to a method for cleaning a protective device () for a drive assist system (), comprising an optical sensor () having an optic (), the protective device () having an optical element () arranged upstream of the optic () and having an inner surface () and an outer surface () and being movably mounted about an axis of rotation (A), the method comprising the following steps: processing a succession of images acquired by the optical sensor () when the optical element () is rotating, so as to detect a generally circular or semi-circular shape which is centred on the axis of rotation (A) of the optical element () and which is generated by dirt deposited on the outer surface (), and triggering at least one action for cleaning the outer surface () of the optical element () if the shape is detected. The invention also relates to an associated drive assist system ().",
