The disclosure relates to a vehicle roof module for a sensor. The module includes a wiper assembly with a wiper blade carried on a wiper arm, and a sensor housing with a visor, and a sensor having a field of view aligned with the visor, The roof module further includes a guide defining a wiping path and a parking path and a slide configured for sliding the wiper assembly over the guide along the wiping path and the parking path. When sliding the wiper assembly over the wiping path slides the wiper arm along the sensor housing such that the wiper blade wipes the visor and when sliding the wiper assembly over the parking path slides the wiper arm along the sensor housing while the wiper blade is lifted from the visor.

One or more vehicles, vehicle systems, computer-implemented methods, and computer program products to enhance the situational competency and/or the safe operation of a vehicle by automatically causing a cleaning sequence of one or more movable vehicle window glass based on window glass cleanliness analysis and a determination that the vehicle window glass is unclean.

An automatic wiper control system for a vehicle window determines the presence of rainfall based on window vibrations. During a vehicle driving cycle, a controller measures the window vibrations with an accelerometer attached to the window. The controller calculates a psycho-acoustic metric based on the measured vibrations, wherein the metric can be comprised of Articulation Index, Sharpness, or Roughness. The calculated metric is compared to a threshold indicative of rain impacting the window. The wiper system is activated according to a result of the comparison.

A motor with speed reduction mechanism is provided with an anti-scattering cover 80 for grease, which holds grease applied to a mating part MT where a worm 36b and a worm wheel 40 are in engagement with each other, the anti-scattering cover 80 for grease is provided and closer to an opening 32c than the worm wheel 40 along an axial direction of the worm wheel 40. The anti-scattering cover 80 for grease has: a first wall 81 extending from the opening 32c toward a bottom 32a and formed between the worm 36b and a side wall 32b of a speed reduction mechanism housing unit 32; and a second wall 82 extending in a direction intersecting with the first wall 81 and covering the mating part MT from the same side as the opening 32c along the axial direction of the worm wheel 40. The first wall 81 and the second wall 82 of the anti-scattering cover 80 for grease hold grease attached to the worm 36b, thereby preventing exhaustion of grease applied to the mating part MT where worm 36b and the worm wheel 40 are in engagement with each other.

A system for a vehicle wiper is disclosed. The system comprises a first rain sensor disposed on a fore portion of a vehicle and a second rain sensor disposed on an aft portion of the vehicle. The system further comprises a controller configured to suspend a rain sensing activation identified during a monitoring cycle in response to a control event. The control even comprises detecting moisture with the first rain sensor for a delay time without detecting the moisture with the second rain sensor.

A vehicle configured to automatically clear snow from windows of the vehicle includes: a prime mover, a first window with a first vibration sensor, processor(s) configured to: control speed or load of the prime mover to increase vibration detected by the first vibration sensor, control the speed or the load of the prime mover, within certain predetermined limits, to maximize vibration detected by the first vibration sensor; accept a user prioritization of the windows; control speed or load of the prime mover based on the user prioritization.

A rain sensor according to an embodiment comprises: a substrate; a sensing electrode formed on a first surface of the substrate; a reaction layer formed on the first surface of the substrate and burying an upper surface of the substrate and the sensing electrode; a driving unit electrically connected to the sensing electrode formed on the first surface of the substrate and processing a sensing signal transmitted through the sensing electrode; and a protective layer formed surrounding the driving unit, wherein an impedance value according to a change of at least one of a force and a dielectric constant caused by presence of rainfall is changed, and the sensing electrode transmits the sensing signal with respect to a variation amount of the impedance value of the reaction layer to the driving unit.
