A vehicle wiper control apparatus monitors whether warpage occurs in a wiper strip made of a rubber-elastic material that is provided in a wiper blade. When a wiper of a vehicle is turned off and the warpage occurs in the wiper strip, the control apparatus controls the wiper mechanism to move the wiper blade to a parking position thereby preventing deformation of the wiper strip and maintaining the performance thereof.

A sensor enclosure comprising a domed cover and a base. The base can be encased by the domed cover. The base comprises an inner frame, an outer frame, one or more wipers, and a powertrain. The inner frame can provide surfaces for one or more sensors. The outer frame, disposed underneath the inner frame, the outer frame includes a slewing ring. The slewing ring comprises an inner ring to which the domed cover is attached and an outer ring attached to the outer frame. The one or more wipers extends vertically from the outer frame, each wiper having a first end attached to the outer frame and a second end attached to a support ring, and each wiper making a contact with the dome cover. The powertrain, disposed within the outer frame, configured to rotate the ring and the dome cover attached to the inner ring.

The invention relates to a gear motor (1) for a motor vehicle wiper system including an electric motor (2) including a rotor (20) and a rotation shaft (22) fixed to the rotor, a reduction gear mechanism (3) including a worm/worm wheel system, a device for generating an axial load configured to offset axial play of the rotation shaft (22), including a retaining wedge (6) mounted in a sliding manner in a radial direction of said rotation shaft (22), said retaining wedge (6) exerting an axial load on the outer race of a ball bearing (5) configured to guide the rotation shaft. According to the invention, said retaining wedge (6) is arranged in an intermediate position between the seat (40) of the bearing support (4) and the worm (30) directly adjacent to the worm wheel (31), said axial load (Fa) exerted by the retaining wedge (6) on the outer race (51) of the ball bearing (5) being in the direction away from the worm (30).

An autonomous vehicle includes a front bumper comprising an opening; a light detection and ranging (LiDAR) sensor comprising a surface exposed to the opening of the front bumper; and a sensor cleaning device configured to remove foreign materials on the surface. The sensor cleaning device includes a wiper configured to move over a surface of a sensor to remove foreign materials from the surface of the sensor; and a movement unit connected to the wiper and comprising at least a linkage system configured to perform folding and unfolding movements, which causes the wiper to reciprocate over the surface of the sensor.
