A method of defogging an inner surface of a vehicle windshield glass. The method includes a first process of defogging by changing a heating, ventilation, and air-conditioning (HVAC) system from a heating mode to a cooling mode when fogging occurs on the inner surface of the vehicle windshield glass; once the inner surface of the vehicle windshield glass is changed to a defogging state by the first process, a second process of pre-defogging by turning off a compressor of the HVAC system for a predetermined period of time under a prescribed condition to prevent flash fogging; and after the second process, when the predetermined period of time elapses, a third process of turning on the compressor to return from the cooling mode to the heating mode.

A system for clearing precipitation from a window comprises one or more transducers (1-8) fixed to the window. The transducers are driven by a generator (13) to produce surface acoustic waves that propagate through the window. The window may be a laminated window such as a windscreen (10) for a vehicle. A sensing system (122) may be used for detecting the presence of precipitation to actuate the clearing system.

An automobile window glass includes a glass substrate, a black ceramic layer and a water absorbing antifogging film. The black ceramic layer is formed in a peripheral portion on a vehicle-interior side main surface of the glass substrate. The water absorbing antifogging film is formed on the vehicle-interior side main surface of the glass substrate and is located in an inner peripheral side relative to the peripheral portion. A space of more than 1 mm and less than 30 mm exists between the black ceramic layer and the water absorbing antifogging film on the vehicle-interior side main surface of the glass substrate.

An imaging system mounted on a vehicle is proposed. The imaging system includes: an imager configured to capture an image of the outside of a vehicle through a glass of the vehicle; a heater configured to heat at least an imaging region of a windshield included in an imaging range of the imager; an image processer configured to detect a fogging level of an image captured by the imager; and a controller configured to adjust the output of the heater based on a detected fogging level and allow the heater to heat the imaging region of the windshield.

A polymeric vehicle glazing is described, having an outer face and an inner face, with a transparent polymeric component at the outer face and the inner face. An opaque polymeric component is flush mounted at the inner face in at least one section of the transparent polymeric component.

The subject of the present invention is a device (3) for protecting an optical sensor (13) of a driver-assistance system (1) for a motor vehicle, the optical sensor (13) comprising an optic (14), and the protecting device (3) including: an optical element (9) that is configured to be positioned upstream of the optic (14) of the optical sensor (13) and mounted so as to be movable about an axis of rotation (A1); and an actuator (5) that is configured to rotate the optical element (9), characterized in that the protecting device (3) further includes: at least one heating component (7) that is configured to heat the optical element (9) so as to defog or defrost this optical element (9); and an induction system (8) that is configured to supply power to the heating component (7).

The invention relates to a motor vehicle deicing fluid comprising: at least one alkali metal salt, the weight percentage of all of the at least one alkali metal salt, in the fluid, being between 0.0001% and 50%, and at least water, the weight percentage of water in the fluid being between 0.0001% and 99.9999%.

Method and apparatus are disclosed for infrared sensor arrays for monitoring vehicle occupants and windows. An example vehicle includes a side window and an infrared sensor array. The infrared sensor array includes first pixels of measurement resolution to monitor an occupant and second pixels of measurement resolution to monitor the side window. The example vehicle also includes a cabin environment controller to detect, via the first pixels, whether a body temperature of the occupant is outside a predetermined temperature range and detect, via the second pixels, whether fog is on the side window.
