In a system for controlling a headlight of a vehicle to be controlled, a dazzling level determiner determines a parameter value of a dazzling level of a driver of an other vehicle ahead of the controlled vehicle based on information associated with a relative positional relationship between the controlled vehicle and the other vehicle. The dazzling level represents a possibility that the driver of the other vehicle feels dazzling to light irradiated from the headlight of the controlled vehicle. A light-quantity adjuster adjusts a quantity of light to be irradiated from the headlight of the controlled vehicle based on the determined parameter value of the dazzling level.

System for controlling light quantity of headlight

A driving support system for use in a vehicle uses a headlight controller for directing a headlight beam on a road surface in an intersection when the vehicle stops at the intersection. Another vehicle simultaneously approaching the intersection detects the beam of the surface with an image sensor and processor of the driving support system. The system of the another vehicle sends back a vehicle ID signal to the stopping vehicle when a predetermined beam pattern is recognized by the processor. Then, the system uses a buzzer for notifying a driver of the stopping vehicle that the ID signal has been returned.

An illumination control unit includes an automatic control function for automatically controlling the turning on and off of vehicle head lights depending on brightness of an environment around a vehicle. A sensitivity adjuster is installed on a lever extending from a steering column in a vehicle compartment. The sensitivity to the brightness of the environment around the vehicle at the time when the auto-on and auto-off state of the vehicle lights is changed can be adjusted with the sensitivity adjuster.

A raindrop sensor includes an image sensor and an image processor. The image sensor captures an image of a windshield from inside a vehicle. The image processor performs a frequency analysis of the image to detect a high-frequency component in the image. When the high-frequency component is detected, the image processor detects a width of a change region where a change in gradation of the image occurs. When the width of the change region is within a predetermined range corresponding to a diameter of a raindrop, the image processor determines that the raindrop is on the windshield. Even when a foreign matter such as a water stain appears as the high-frequency component as a result of the frequency analysis, the raindrop and the foreign matter can be distinguished from each other based on the width of the change region.

A vehicle light control apparatus includes an illumination control unit for executing illumination control on the mode of illumination of a subject vehicle based on signal transmission of a vehicle ID signal unique to the subject vehicle and signal reception of the vehicle ID signal unique to the subject vehicle. The control unit identifies a vehicle having brightness exceeding a predetermined threshold from an image of other vehicles acquired through an image recognition MPU as a vehicle having an illumination adjustment failure, and returns the same vehicle identification signal transmitted from the other vehicle thus identified to vehicles other than the subject vehicle.

Vehicle light control apparatus, system and method

An organic EL device has a structure in which an anode, a hole transporting layer, an organic luminescent layer, and a cathode are disposed on a glass substrate in this order. The organic EL device further has a protective layer covering an outer surface of the structure to protect it from an external environment. The protective layer is formed by an ALE method at a temperature lower than glass transition temperatures materials constituting the hole transporting layer and the organic luminescent layer.
