A method for setting a characteristic of a light emission of at least one headlight of a vehicle, in which the method includes reading in concealment data which represent at least one property of at least one concealment object situated adjacent to a roadway in surroundings of the vehicle. In addition, the method includes ascertaining a distance between the vehicle and a segment of the roadway situated in the forward travel direction of the vehicle, adjacent to the at least one concealment object, using the concealment data. Moreover, the method includes adapting a waiting time period and/or waiting distance for changing the characteristic of the light emission from a first characteristic to a second characteristic as a function of the ascertained distance.

A vehicle headlight control apparatus controls headlights of a vehicle including LEDs. The vehicle headlight control apparatus includes: drivers and each of which gradually changes a luminance of the LEDs between a predetermined on state and a predetermined off state over a switching time period; and a lamp ECU that determines the switching time period in a changeable manner.

An imaging system is provided herein. An image sensor is configured to acquire one or more images of a scene external and forward of a controlled vehicle and to generate image data corresponding to the acquired images. A controller is communicatively connected to the image sensor and is configured to receive and analyze the image data. The controller detects an object of interest in the image data and generates an ON signal or an OFF signal based on the detection of the object of interest in the image data, or lack thereof. A high beam control of the vehicle is turned ON based on the ON signal or turned OFF based on the OFF signal. The controller modifies a future response time at which the OFF signal is generated based on an external overriding of the ON signal or the OFF signal.

A lighting system for a vehicle is described, which includes a first hybridized device, a second hybridized device and a controller. The first hybridized device includes a first array of light emitting devices that illuminate a roadway on which the vehicle is located when operating. The second hybridized device includes a second array of light emitting devices that illuminate the roadway on which the vehicle is located when operating. The controller is electrically coupled to the first and second hybridized devices. When operating, the controller causes the first hybridized device to selectively project a first patterned light on to an object on the roadway, causes the first hybridized device to selectively project a second patterned light on to the object on the roadway, and causes a first camera to capture an image of the first patterned light projected on the object and the second patterned light projected on the object.

A first light emitting unit includes M (M2) first light emitting elements provided in series. A second light emitting unit including N (N<M) second light emitting elements and a switching transistor are provided on a path parallel to the first light emitting unit. A constant-current driver is connected in series to both the first light emitting unit and the second light emitting unit, and generates a drive current. A drive circuit includes a capacitor provided between a gate and a drain of the switching transistor, and causes the gate of the switching transistor to generate a drive signal according to a switching signal.

A camera is described that includes a first imager and a processor communicatively coupled to the first imager. The first imager captures images of a roadway on which a vehicle is located when operating. The processor, when operating, generates a signal to cause a first hybridized device in the vehicle to project a first patterned light on to an object on the roadway, generates a signal to cause the first imager to capture an image of the first patterned light projected on the object, receives the image from the first imager, and detects the object on the roadway based on the first patterned light captured in the image.

A headlight control system (10) for a motor vehicle including, a controllable headlight (24) adapted to generate variable illumination of the vehicle environment, an imaging apparatus (11) adapted to capture images (100) from a region in front of the motor vehicle, and a data processing device (14) adapted to perform image processing of images (100) captured by the imaging apparatus (11) and to vary the light characteristics of the controllable headlight (24) depending on the image processing. A machine learning model (27) is implemented in the data processing device (14) which is trained to estimate and output an output signal (29) representing a desired illumination of the vehicle environment from one or more images (28) received as input from the imaging apparatus (11).

A method for setting at least one parameter of a driver assistance device of a vehicle includes reading in concealment data which represent at least one property of at least one concealment object situated adjacent to a roadway in a surroundings of the vehicle. The method also includes ascertaining a concealment-related visual range from the vehicle in an area of the surroundings situated in the forward travel direction ahead of the vehicle, using the concealment data. Finally, the method includes adapting the at least one parameter as a function of the concealment-related visual range.

A Light control device 10 having a control unit 11 for controlling irradiation state of a light unit 2 provided in a vehicle 1, wherein the control unit 11 is configured to execute following processes, executing an automatic irradiation mode for automatically switching the irradiation state to a high beam state or a low beam state based on detection values for detecting an environment around the vehicle, in the high beam state, in a case where a cancel operation of the automatic irradiation mode is input, switching the irradiation state to the low beam state during an interruption time, and adjusting an interval of the interruption time according to operation contents of the cancel operation.

A vehicle headlight (1) includes a lamp unit (10) capable of changing a light distribution pattern of emitted light, and a control unit (CO) that controls the lamp unit (10) based on information input from a detection device (120) that detects a predetermined object located in front of a vehicle (100). The control unit (CO) controls the lamp unit (10) to emit light having a light distribution pattern (PH) of a high beam including an additional light distribution pattern (PAH) in a case where the predetermined object is not detected, and in a case where the predetermined object is detected, controls the lamp unit (10) so that a light amount of a first region (91a, 91b, 91c) overlapping at least a part of the predetermined object in the additional light distribution pattern (PAH) decreases and a light amount of a second region (92) different from the first region (91a, 91b, 91c) increases at a predetermined magnification or by a predetermined amount, as compared with the case where the predetermined object is not detected.
