A front quarter glass includes a window plate, a frame-like black ceramic layer on a peripheral portion of an interior side surface, and an anti-fogging film provided in a region excluding an entire peripheral portion of the window plate. A boundary is between the regions where the anti-fogging film is provided and not provided, has no perspective distortion, and has a boundary line of 10-200 m that is visually recognized by scattering of incoming light. An outer periphery of the anti-fogging film is located is located 8 mm (0.31 inch) inside from an inner periphery of the black ceramic layer in a first region. The first region is to less than 50% of an entire inner periphery including a lower front portion. The outer periphery of the anti-fogging film is located 8-35 mm (0.31-1.38 inches) inside the inner periphery of the black ceramic layer in a second region excluding the first region.

An optical device includes an optical unit that is disposed with a closed space interposed between the optical unit and a windshield glass and is configured to acquire information of an outside of a vehicle cabin through the windshield glass, a heating unit that heats the closed space, an opening and closing unit that is disposed in an air flow path between the closed space and a vehicle cabin internal space and controls communication of air between the closed space and the vehicle cabin internal space, and a controller that controls an open and closed state of the opening and closing unit based on either an outside air temperature of a vehicle or a difference in humidity acquired by subtracting a humidity of the vehicle cabin internal space from a humidity of the closed space.

A heating system for a vehicle is provided. In order to permit provision of efficient heating of a vehicle window pane of an electric vehicle, the system has two at least mainly transparent panes, wherein an outer pane is arranged on the outside of the vehicle and an inner pane is arranged on the inside of the outer pane to form an intermediate space, and at least one controllable infrared source is configured to irradiate infrared radiation into the intermediate space so that the infrared radiation at least partially irradiates the outer pane.

A system mounted on a vehicle for detecting an obstruction on a surface of a window of the vehicle, a primary camera is mounted inside the vehicle behind the window. The primary camera is configured to acquire images of the environment through the window. A secondary camera is focused on an external surface of the window, and operates to image the obstruction. A portion of the window, i.e. window region is subtended respectively by the field of view of the primary camera and the field of view of the secondary camera. A processor processes respective sequences of image data from both the primary camera and the secondary camera.

The present invention relates to a camera module for a vehicle, including: upper and lower housings having therein an accommodation space; a lens holder accommodated in an internal space of the upper housing and having a protruding first opening part; a lens barrel inserted into an upper portion of the first opening part; a heat generating member interposed between the lens holder and the lens barrel and having a second opening part having an inner diameter larger than an outer diameter of the first opening part; and a lower board accommodated in an internal space of the lower housing and mounted with an image sensor at a position corresponding to the lens barrel.

A system and method for sensing precipitation conditions near a vehicle. The precipitation radar system is mounted on the vehicle and includes a transmitter, a receiver, and an electronic control unit. The method transmits radar signals from the transmitter; receives reflected radar signals at the receiver; determines response information from the reflected radar signals for a region of interest; and uses the response information to determine precipitation conditions for the region of interest. The region of interest is defined, at least in part, by a range and the response information includes phase data, amplitude data, or both phase and amplitude data based on the reflected radar signals. The method and system may then use the precipitation conditions to control other responsive vehicle actions, such as activating a windshield heater, a windshield defroster, a windshield wiper or a combination thereof.

An air conditioner for a vehicle includes: a casing; an air blower; and a mode switching portion switching an inlet mode to draw air into the casing and an outlet mode to blow out air to the vehicle interior. The casing has a driver seat inlet port from which air in a space adjacent to a driver seat is drawn in. The mode switching portion is configured to be switchable between a normal mode during which air drawn in from at least one of air inlets is blown out from both of a driver seat outlet and a passenger seat outlet and a driver seat mode during which air drawn in from the driver seat inlet port is blown out from the driver seat outlet. The driver seat inlet port is located in a region exposed to the space adjacent to the driver seat.

Relative humidity or dew point temperature depending on changes in barometric pressure is measured without using any barometric pressure sensor. A humidity measuring device includes an elevation obtaining unit configured to obtain elevation of a humidity measurement point, a barometric pressure calculating unit configured to calculate barometric pressure at the humidity measurement point from a calculation formula into which a value of the elevation obtained by the elevation obtaining unit is input, and a humidity correcting unit configured to correct humidity on a basis of a barometric pressure value calculated by the barometric pressure calculating unit.

An apparatus comprising an interface and a processing circuit. The interface may be configured to receive (a) a video signal based on a targeted view in a vehicle and (b) one or more status signals from one or more sensors of the vehicle. The processing circuit may be configured to (A) analyze the video signal received from the interface and (B) detect a type of obstruction of a window of the vehicle visible in the video signal in response to (i) a classification of information in the video signal and (ii) one or more of the status signals. The processing circuit may (a) determine a confidence level for the type of obstruction, (b) activate one or more corrective measures when the confidence level is above a pre-defined threshold and (c) adjust the confidence level based on a response of the obstruction to the corrective measures.

The invention relates to a window glass heating apparatus comprising an electric heating wire for heating a window glass of a vehicle. The apparatus continues to stop an energization of the wire until a predetermined energization standby time has elapsed after an energization permission condition becomes satisfied. The apparatus starts the energization of the wire when the predetermined energization standby time has elapsed after the energization permission condition becomes satisfied.
