Abstract
The utility model relates to a control system capable of adjusting backlight color and brightness of an instrument inside an automobile. The control system comprises a man-machine input interface, an instrument, an automobile body controller, a light modulator, three-primary-color LED lamps, and peripheral equipment, the man-machine input interface or the peripheral equipment transmits a signal to the light modulator through the instrument or the automobile body controller, the light modulator converts the signal to three data components of R, G, and B and transmits the data components to the three-primary-color LED lamps, the luminous intensity of three primary colors in the three-primary-color LED lamps is controlled through three paths of control signals, different brightness combinations of the three primary colors form different colors and brightness, and thus the system can achieve an effect that colors and brightness of all luminous sources inside the automobile are adjustable and variable.
Description
Technical field
The utility model relates to automotive field, control system and the method for the inner instrument backlight color of especially a kind of adjustable automobiles and brightness.
Background technology
Chinese Business Car experienced several years flourish after, enter a tranquilization, sustainable development stage, except solid, durable, people are also at the product, particularly commercial car interior trim of pursuing a kind hommization, personalization, and client wishes in steering vehicle, can experience a kind of relaxation, joyful sense, warm sense, commercial car combination instrument is again as an important interior trim man-machine interface, and its display effect, directly affects client's subjective consciousness.Domestic commercial vehicle combination instrument is monochromatic light at present, dullness backlight, only brightness backlight is adjustable, because client likes difference, also different to combination instrument perception backlight, so Unicolor back light only can meet part client hobby, cannot meet more customer demand, and long-term driving of Unicolor back light combination instrument client easily produced sheet visual fatigue.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides control system and the method for the inner instrument backlight color of a kind of adjustable automobiles and brightness.
The control system of the inner instrument backlight color of a kind of adjustable automobiles and brightness, described system comprises man-machine input interface, instrument, car body controller, dimmer, three-primary color LED lamp, ancillary equipment, man-machine input interface or ancillary equipment are transferred to dimmer by instrument or car body controller by signal, and dimmer converts signal three primary colors R, G, tri-data components of B to and sends three-primary color LED lamp to.
Described ancillary equipment comprises transducer, instrument alarm lamp.
The signal that described dimmer sends instrument or car body controller converts R, G, tri-data components of B to, and control the luminous intensity of three kinds of primary colours in three-primary color LED lamp by three tunnel control signals, three kinds of brightness combinations that primary colours are different, form different colors and brightness.
Described San road control signal adopts three road pwm pulse modulation waveforms, and the three primary colors component value receiving according to bus, by using different duty ratios, is controlled the luminous intensity of three kinds of primary colours.
Described three primary colors R, G, B adopt 16 rank brightness.
The utility model has the advantage of: each luminous component in car load inside (instrument, DVD, illuminating lamp, atmosphere lamp, knob, button etc.) can be realized unified variable color backlight and the technology of brightness regulation, realize under different conditions, the light color of automotive interior and brightness can change.
Brief description of the drawings
The control system structure chart of Fig. 1 the utility model embodiment.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is as the effect of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, with help those skilled in the art to utility model of the present utility model conceive, technical scheme has more complete, accurate and deep understanding.
Rgb color pattern: RGB is a kind of color standard of industrial quarters, by variation and their stacks each other of red (R), green (G), blue (B) three Color Channels are obtained to color miscellaneous, RGB is the color that represents three passages of red, green, blue, this standard almost comprised mankind eyesights can perception all colours, be to use at present one of the widest color system.
Three Color Channels of red, green, blue adopt 256 rank brightness, the most weak at 0 o'clock " lamp "---turn off, and the brightest at 255 o'clock " lamp ".Be the gray color of achromatization when three chromatic numbers are worth when identical, and three looks are all within 255 o'clock, to be the brightest white, in the time that three looks are all 100, are the white of intermediate light.But in actual vehicle backlight color design use procedure, will not assign to 256 ranks in brightness region, use 16 rank brightness can realize 16*16*16 kind color, enough use backlight in car.
Car load adjusting control backlight: backlight color brightness communication is used the total line traffic control of CAN, (for example: become backlight greatly with the speed of a motor vehicle and reddened again by green flavescence gradually work as precondition by instrument or car body controller 102 foundations, prompting driver etc. reddens while having alarm condition) or be artificially input to instrument by button etc. or BCM realizes color and the brightness of controlling vehicle interior again, instrument or car body controller 102 periodically send out car load backlight color and brightness RGB component data, all the other luminous nodes receive this data from CAN network, control brightness backlight and color.In the CAN data that initiatively sending node sends, need to increase by tri-parameters of definition R:G:B.If adopt the brightness of 256 ranks, take altogether the data width of 3 bytes.Adopt the brightness of 16 ranks, can take the CAN frame data width of 1.5 bytes.
Automotive interior luminous component different colours and brightness realize principle: overwhelming majority employing LED backlight in automobile now, the LED of LED manufacturer production three primary colors, the LED of three primary colors respectively Yong San road controls inner three primary colors, can Yong San road pwm pulse modulation waveform control.Use different duty ratio (according to the component value of the three primary colors that receive on CAN network), control the luminous intensity of three kinds of primary colours in LED, three kinds of brightness combinations that primary colours are different, form different colors and brightness.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
