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 ().

The present invention relates to a system for cleaning at least two sensors/transmitters for a motor vehicle, the system comprising at least one first device for projecting a cleaning fluid onto at least one first sensor/transmitter, at least one second device for projecting a cleaning fluid onto at least one second sensor/transmitter, at least one reservoir, at least one circuit for distribution of the cleaning fluid, connecting the reservoir to the first and second projection devices, at least one electronic pump, and at least one control unit, characterized in that the control unit is configured to receive information on a request for activation of the first and/or second projection device(s) in order to determine a theoretical value of at least one operating parameter of a pump.

System for cleaning at least two sensors/transmitters for a motor vehicle

System for cleaning a glazed surface of a motor vehicle, including at least one wiper and a drive device for driving at least the wiper along an axis of translation, substantially perpendicular to said wiper, where the glazed surface is a detection surface of a sensor/emitter of a detection assembly and in that the drive device includes at least one drive motor driving in rotation about an axis of rotation substantially perpendicular to the axis of translation, and at least a conversion device converting a rotational movement of the drive motor into a rectilinear movement along the axis of translation.

The invention relates to a device for remotely giving warning as to the state of wear of at least one blade of a windshield-wiper system of a vehicle comprising means for determining the wear of said blade and means for flagging said wear; said device is noteworthy in that it comprises at least one unit comprising a module called the removable diagnostic connector able to interact with a diagnostic service connector forming an on-board diagnostic input of the vehicle in order to establish a link with said diagnostic connector via the OBD protocol and means for communicating electronically that are coupled to the diagnostic connector and that are able to transmit, to a portable electronic apparatus, via a wireless link, a message indicating the wear of said blade when the means for determining the wear of the blade generate a signal referred to as a wear signal.
