Realize the technical scheme of the object of the invention:
A light control method for luminous component in car, is characterized in that: extraneous light luminance signal is sent to car body controller BCM by light sensor, and car body controller BCM controls the light luminance of luminous component in car according to extraneous light luminance signal.
Car body controller BCM, according to extraneous light luminance signal, controls interior light unit and switch backlight unit, regulates the brightness of interior light light and switch backlight.
Extraneous light luminance signal is sent to instrument pack and DVD unit by CAN network by car body controller BCM, and instrument pack and DVD unit, according to extraneous light luminance signal, distinguish the brightness of regulation meter backlight and DVD display backlight.
DVD read-out is provided with sensivity to light by-pass cock, and chaufeur can input the instruction of light sensitivity in the mode touched, and the instruction of light sensitivity is sent to car body controller BCM and instrument pack by CAN network; Car body controller BCM, according to the instruction of light sensitivity and extraneous light luminance signal, regulates the brightness of interior light light and switch backlight; Instrument pack is according to the brightness of the instruction of light sensitivity and extraneous light luminance signal regulation meter backlight; DVD unit regulates the brightness of DVD display backlight according to the instruction of light sensitivity and extraneous light luminance signal.
Light sensor is installed on inside front windshield glass, and light sensor meets car body controller BCM by LIN bus.
Interior light unit is ceiling light or atmosphere lamp.
Car body controller BCM regulates the brightness of interior light light and switch backlight, realizes by regulating the PWM dutycycle of power supply.
The beneficial effect that the present invention has:
The present invention is provided with light sensor, extraneous light luminance signal is sent to car body controller BCM by light sensor, car body controller BCM controls the light luminance of luminous component in car according to extraneous light luminance signal, namely realizes the automatic adjustment to luminous component light luminance in car.Car body controller BCM of the present invention is according to extraneous light luminance signal, automatically the brightness of interior light light and switch backlight can be regulated, also can the brightness of automatic controller backlight and DVD display backlight, without the need to chaufeur manual regulation, use convenient, more contribute to traffic safety.
Light sensor of the present invention is installed on inside front windshield glass, and light sensor meets car body controller BCM by LIN bus, and extraneous light luminance signal is sent to instrument pack and DVD unit by CAN network by car body controller BCM, and structure is simple, easy for installation.
DVD read-out is provided with sensivity to light by-pass cock, and chaufeur can input the instruction of light sensitivity in the mode touched, and the instruction of light sensitivity is sent to car body controller BCM and instrument pack by CAN network; Car body controller BCM, according to the instruction of light sensitivity and extraneous light luminance signal, regulates the brightness of interior light light and switch backlight; Instrument pack is according to the brightness of the instruction of light sensitivity and extraneous light luminance signal regulation meter backlight; DVD unit regulates the brightness of DVD display backlight according to the instruction of light sensitivity and extraneous light luminance signal, and light regulates hommization more, and further lifting operation is experienced.
