Abstract: The present invention relates to a cleaning device for cleaning at least one optical system of a vehicle, comprising an actuator which has an actuator body which delimits a chamber, a piston with the ability to move in the chamber, and a rod connected to the piston, one end of the rod emerging from the actuator body, said rod comprising at least one cleaning-fluid-spraying element formed at the end of the rod, the rod comprising at least one cleaning-fluid circulation duct which connects the chamber to said at least one spraying element, characterized in that the cleaning device comprises at least one switch activated according to the position of the piston.

Abstract: The device for discharging liquids for a module includes sensor/transmitter blocks for a vehicle. The module includes a first block having a lower optical surface having an upper limit, and at least one second block having at least one upper optical surface with a lower limit arranged above the lower optical surface. The device extends from an area defined by at least one portion of the lower limit of the at least one second block and the upper limit of the first block, and is configured to discharge liquids flowing from the at least one upper optical surface to an area other than the lower optical surface.

Abstract: The invention relates to a method for automated cleaning of an optical surface of a motor vehicle, comprising at least one cycle of cleaning (38) the optical surface which comprises a plurality of separate and successive steps of spraying fluid, said cycle of cleaning (38) comprising at least a first step of spraying (30) cleaning fluid onto the optical surface, a second step of spraying (32) cleaning fluid onto the optical surface, and a break step (34), of non-zero duration, between the first step of spraying (30) cleaning fluid and the second step (32) of spraying cleaning fluid.
