An absolute pitch is outputted from an inclination sensor. A gradient related quantity is outputted from a gradient related quantity detection sensor for detecting a gradient related quantity that can specify a gradient of a road surface. The absolute pitch angle and the gradient related quantity are acquired by a vehicle headlight control apparatus. Based on the absolute pitch angle and the gradient related quantity, a pitch angle of a vehicle with respect to a road surface is calculated by the vehicle headlight control apparatus. Based on the pitch angle, an optical axis direction of the head lamp is controlled by the vehicle headlight control apparatus.

A device for assisting the nighttime driving of a motor vehicle fitted with a lighting device for emitting a beam for illuminating the road scene in front of the vehicle, the illumination emitted by the lighting device being variable periodically between a maximum value and a minimum value, the device including at least one variable-transmission screen placed between the road scene and the driver, the coefficient of transmission of the screen being variable periodically between a maximum value and a minimum value, the switching on of at least one light source of the lighting device and the coefficient of transmission of the variable-transmission screen controlled by the control unit, the illumination reaching its maximum value when the coefficient of transmission of the screen reaches its maximum value. The control unit controls a circuit for regulating the power supply and a transmitter of remote control waves toward a receiver.

An adaptive light system including a color matching engine, a controller, and a plurality of light sources each configured to emit a source light. The color matching engine determines a dominant wavelength of a selected color, and a combination of the light sources that the controller may operate to emit a combined wavelength that approximately matches the dominant wavelength of the selected color. A color capture device transmits a source color signal designating the selected color. A method of adapting light comprises receiving a selected color, converting a value representing a dominant wavelength of the selected color, determining a combination of and percentages of colors emitted by the plurality of light sources that may be combined to form an adapted light that matches the selected color, and operating the light sources along with a white light to emit the adapted light.

This disclosure relates generally to controlling headlights and more particularly to a system and method for automatically controlling vehicle headlights using image processing techniques. In one embodiment, a Headlight Controlling Device for automatically controlling vehicle headlights is disclosed. The Headlight Controlling Device comprises a processor and a memory communicatively coupled to the processor. The memory stores processor instructions, which, on execution, causes the processor to collect at least one of vehicle information, vehicle speed, road information, area information, weather information or a multimedia object associated with a forward path of the vehicle. The processor further determines a current light intensity distribution of the vehicle headlight based on the multimedia object. The processor further compares the current light intensity distribution of the vehicle headlight with an optimal light intensity distribution, wherein the optimal light intensity distribution is retrieved from a database based on at least one of the vehicle information, the vehicle speed, the road information, the area information or the weather information. The processor further controls the vehicle headlight based on the comparison.

A headlamp for vehicles has a housing containing a light source unit with numerous light sources, and an optical unit for generating a predefined light distribution. A cover lens covers a light-emitting aperture in the housing. A control unit is provided for the light sources. An anti-condensation means prevents condensation on a surface of the optical unit and/or the cover lens. The control unit contains a control program to operate the light source unit at an anti-condensation level higher than the normal level for generating the predefined light distribution. The difference between the anti-condensation level and the normal level is great enough that a relative humidity within the housing in an anti-condensation state is lower than in the normal state. Light sources in the light source unit that are not intended for generating the predefined light distribution are also switched on, in addition to those intended for such.

A method for operating a headlight device of a motor vehicle, wherein the headlight device comprises a projection device and a control unit which is designed to control the projection device for projecting a predetermined light pattern in a predetermined projection region of the projection device. The light pattern in a polygon operating mode of the headlight device comprises a polygon mesh with polygon surfaces having polygon edges defined by projection points as corner points. At least partially different projection brightnesses are assigned to the polygon surfaces, wherein at least one physical property is assigned to at least one polygon feature of the polygon surfaces, in particular at least to the corner points, wherein, for dynamic adjustment of the light pattern in a dynamic submode of the polygon operating mode: time-current operating data of the motor vehicle and/or measurement data of the motor vehicle are recorded, which describe the driving state of the motor vehicle and/or environmental features relevant to the physical property in an environment of the motor vehicle encompassing the projection region, an environment model is provided based on the operating data and/or measurement data, at least for the projection region, and the polygon mesh is adjusted before the light pattern is output on the basis of a computationally determined item of adjustment information that describes a virtual physical interaction of the polygon surfaces with the environment model on the basis of the at least one assigned physical property.

A road surface drawing apparatus for a vehicle includes a road surface drawing lamp that irradiates a patterned light and a controller that controls the road surface drawing lamp. The controller determines a plurality of conditions including a first condition, a second condition, and a third condition each time the vehicle travels a fixed distance. The first condition is that the outside temperature of the vehicle is equal to or lower than a predetermined temperature. The second condition is that a brightness of light reflected from an area illuminated by a headlight of the vehicle is equal to or lower than a predetermined brightness. The third condition is that at least one of ABS, ESC, and TRC has been activated during the most recent predetermined distance traveled by the vehicle. The controller performs a glare reduction control of the patterned light when the plurality of conditions is satisfied.
