The present invention relates to a device for cleaning at least one optical surface of a vehicle, including at least one rod which extends mainly along a longitudinal elongation axis. The rod including an element for spraying a cleaning fluid and a wiper blade configured to wipe the optical surface. The device further including at least one actuation means driven to move the rod in a first longitudinal direction of movement parallel to the longitudinal elongation axis, and in a second longitudinal direction of movement opposite to the first longitudinal direction of movement. The device additionally includes at least one means for limiting and/or compensating for at least one return force exerted on the rod.

A vehicular camera module includes a housing, a camera disposed in the housing, and a transparent cover mounted at the housing. The camera views through the transparent cover. A wiper element is movable relative to the transparent cover to clean the transparent cover. The wiper element is moved via operation of a hydraulic actuator. With the vehicular camera module mounted at an exterior portion of a vehicle, the camera views through the transparent cover in order to capture image data of a scene exterior of the vehicle. With the vehicular camera module mounted at the exterior portion of the vehicle, the hydraulic actuator operates via pressurized fluid supplied to hydraulic actuator to move the wiper element back and forth across the transparent cover to clean the transparent cover of the vehicular camera module.

A self-centering wiper system for an optical device having an optical device body defined by an outer surface with an annular-shaped cross-section disposed along an axis includes an annular-shaped bellows. The bellows is configured to fit externally and concentrically with respect to the outer surface of the optical device body. The bellows has at least one bladder configured to accept a pressurized fluid to thereby extend the annular-shaped bellows along the axis. The wiper system also includes an annular-shaped wiper element fixed to the annular-shaped bellows and configured to wipe contaminants off the outer surface of the optical device body as the at least one bladder accepts the pressurized fluid and the annular-shaped bellows expands along the axis. An optical device having such a self-centering wiper system is also disclosed.
