A method for processing vehicle camera lens obstructions including obtaining an image from a vehicle camera, generating a first camera lens dirt map according to pixel texture richness and color spectrum levels extracted from the image, obtaining a sequential feed of multiple frames from the vehicle camera, generating a second camera lens dirt map according to at least one salient region extracted from the multiple frames, combining the first camera lens dirt map and the second camera lens dirt map to generate a combined camera lens dirt map, and initiating at least one of automated lens cleaning or a camera lens obstruction signal, according to the combined camera lens dirt map.

A wiper control device includes an acquisition unit, an estimation unit, and a drive unit. The acquisition unit is configured to acquire a value related to a current flowing through a wiper motor that drives a wiper configured to reciprocate between a first position and a second position. The estimation unit is configured to estimate a wiper angle, which is a rotation angle of the wiper, based on a current ripple in the current flowing through the wiper motor. The current ripple has a periodicity corresponding to driving of the wiper motor. The drive unit is configured to reduce an electric power supplied to the wiper motor when a position of the wiper is just before the first position or when the position of the wiper is just before the second position.

A wiper motor has: a magnet disposed on the yoke and formed with at least four poles; an armature disposed on an inner side of the magnet; a speed reduction mechanism unit having an output shaft for transmitting the rotation of the armature shaft; a gear housing connected to the yoke; a gear housing cover covering an opening of the gear housing; a magnet attached to the output shaft of the speed reduction mechanism unit; an absolute position detecting sensor disposed so as to face the magnet; and a control board having the absolute position detecting sensor attached thereto, the control board being disposed between the gear housing and the gear housing cover, and configured to control the rotation of the armature shaft.

A unitary or one-piece integral image sensor and washing nozzle assembly or module 100, 300, 400 is configured to enclose, protect, and aim multiple image sensors and effectively clean multiple lenses (e.g., 102, 104) simultaneously while using only one nozzle head (e.g., 120, 320 or 420) with at least one optimized spray pattern (e.g., 122). The module includes a housing with a cover or bezel (e.g., 106) that supports and orients the lenses and the nozzle head aims spray at the lenses along a spray axis, with the relative heights and spacings of the nozzle's outlet orifice (e.g., 174) and the surfaces of the lenses (e.g., 102, 104) selected so that a particular spray either glances across and washes a nearest lens (e.g., 102) or impacts and washes over a farthest lens (e.g., 104).

A vision control system for controlling a vision of a glass surface of a locomotive. The vision control system includes a sensing module for detecting at least one parameter related to the glass surface. The sensing module includes a moisture sensing device configured to detect a presence of moisture on the glass surface and a photo sensor configured to detect an opacity of the glass surface. The vision control system also includes a cleaning system configured to perform a cleaning operation on the glass surface. The vision control system further includes a controller communicably coupled to the sensing module and the cleaning system. The controller is configured to receive a signal indicative of the at least one parameter related to the glass surface from the sensing module and communicate with the cleaning system to control the cleaning operation based on the received signal.

The invention concerns an output element (15; 151) for a motorisation device (1) for driving at least one windscreen wiper arm of a motor vehicle, comprising an output shaft (17; 171) and a toothed wheel (40) integral to and coaxial with the output shaft (17; 171), characterized in that the output shaft (17; 171) is made of plastic material and in that the output element (15; 151) comprises a metallic insert (16; 161; 162; 163), the plastic material of the output shaft (17; 171) being moulded partially over the metallic insert (16; 161; 162; 163), revealing an insert head (25; 251) protruding from the end of the output shaft (17; 171) and intended to connect to a windscreen wiper element in order to drive this in rotation.

The invention also concerns a motorisation device (1) and a method for production of an output element (15; 151).
