A system may have lights. The lights may be moved using a positioner. Control circuitry may use sensor circuitry to monitor the environment surrounding the system. The sensor circuitry may include one or more sensors to measure the shape of a surface in front of the system and the location of the surface relative to the system. The sensor circuitry may also measure light illumination on the surface. Based on the known shape of the surface in front of the system and the distance of the surface from the system, the control circuitry can predict where a light should be aimed on the surface. By comparing predictions of light illumination on the surface to measurements of light illumination on the surface, the system can determine how to move the light with the positioner to align the light.

A switch device includes a cylindrical movable lever-portion that is operable in multiple directions, a unit case that supports the movable lever-portion, and a flexible printed circuit board routed from an inside of the movable lever-portion to an inside of the unit case. A routed portion of the flexible printed circuit board to be routed inside the unit case includes a stress absorber configured to absorb a stress applied to the flexible printed circuit board. The stress absorber includes a plurality of curved portions curved in opposite directions to each other.

A calibration method includes forming a calibration pattern with a light distribution variable lamp onto a screen located at a distance from the light distribution variable lamp and an imaging device, capturing an image of the calibration pattern with the imaging device, acquiring a correspondence relationship between position coordinates of an image captured by the imaging device and position coordinates of the calibration pattern in a light illumination range, calculating an amount of parallax difference between the light distribution variable lamp and the imaging device, and correcting the correspondence relationship based on the amount of parallax difference and generating mutual position information between the light illumination range and the imaging range.

A vehicle headlamp device includes headlamps, which are structured so as to be able to project or irradiate given patterns and given shapes without distortion on a given virtual surface in front of a vehicle from a left headlight and a right headlight, respectively, a camera that captures an image of the area in front of the vehicle, and a state detecting portion configured to detect distortion of the given patterns, which are projected or irradiated on an irradiated surface in front of the vehicle, relative to the given patterns projected or irradiated on the given virtual surface in front of the vehicle, based on the captured image, and also detect a state of the irradiated surface based on the distortion, and a correcting portion configured to correct a relative optical axis deviation between the left headlight and the right headlight.

A vehicle lamp system includes a camera which generates image information in a front region, a controller which generates a light distribution command for instructing a light distribution pattern based on the image information, a headlight which irradiates the front region such that the instructed light distribution pattern is obtained, and a position calibrator which detects a positional deviation between the camera and the headlight. The position calibrator detects a reference object based on the image information and measures a luminance of the reference object, and when there is a certain difference between a luminance of the reference object obtained from one light distribution pattern and a luminance of the reference object obtained from another light distribution pattern in which a light quantity of only a part is different from the one light distribution pattern, detects the positional deviation using a position of the part.

A method for validating an illumination-range test value of a light cone of at least one headlight of a vehicle. The method includes reading in a reflection intensity of a point on at least one road marking illuminated by the light cone; generating a reflection intensity model for the road marking, based on the obtained reflection intensity and a particular distance of the point from the vehicle, the reflection intensity model being designed to assign different reflection intensities to different positions on the road marking in front of the vehicle; determining an illumination-range plausibility value, at which, according to the reflection intensity model, a reflection intensity is reached, which corresponds to a reflection-intensity threshold value; and comparing the illumination-range plausibility value to the illumination-range test value, to validate the illumination-range test value, if the illumination-range plausibility value is inside a tolerance range around the illumination-range test value.

A method for calibrating a first lighting device, a second lighting device, and an optical sensor includes controlling the first lighting device, the second lighting device, and the optical sensor in a temporally coordinated manner and associating the controlling with a visible distance range. The method further includes capturing a first recorded image with the optical sensor by the controlling during an illumination by the first lighting device, capturing a second recorded image with the optical sensor by the controlling during an illumination by the second lighting device, and forming a differential recorded image as a difference between the first recorded image and the second recorded image. The coordinated controlling and/or the first lighting device and/or the second lighting device is evaluated and/or changed on a basis of the differential recorded image.

A method for controlling a configuration state of at least one vehicle device of a motor vehicle, wherein calibration state data which signal a current calibration state of a self-calibration routine carried out by the calibration device during a driving operation of the motor vehicle are received from a calibration device of the vehicle device in question. A progress value is assigned to the respective current calibration state data in accordance with a predefined evaluation rule and a configuration data set which defines a configuration state of the vehicle device in question is selected from a plurality of predefined configuration data sets depending on the current progress value, and the vehicle device is configured by the selected configuration data set, wherein at least one function parameter is set according to the respective configuration data set for the execution of the least one sub-function.
