Abstract

An adaptive regulator for the headlight of car is composed of a central control unit with MCU chip, a drive executing unit with step motor, a LIN bus transceiver between said central control unit and drive executing unit, and a position feedback module between said MCU chip and step motor. A method for setting up the initial position of headlight and an algorithm for the lighting on curved road are also disclosed.

Description

technical field [0001] The invention belongs to the field of non-portable lighting devices or systems, and in particular relates to a lighting adjustment control device for automobile headlights. Background technique [0002] Automotive lighting devices are important safety components for cars. [0003] Ordinary automobile headlights are fixed structures, and the angle and direction of illumination of the lamps / bulbs (that is, the shape of illumination light) are fixed. In this way, when the vehicle is turning, a lighting blind spot will be generated with the forward direction of the wheel, so that the driver cannot see the road situation clearly, which affects the safety of driving. [0004] Announcement date May 2, 2001, the Chinese patent of announcement number CN 2428356Y discloses a kind of " headlamp and its drive mechanism for removing blindness and deviation with rudder steering ", which is composed of reflector 1 bracket platform 5 and Steering control mechanism i...
