Problems solved by technology

However, the design, production, review, and debugging of prototypes all require a cycle and multi-party collaboration, which makes the vehicle backlight review work only after the hardware and structural design of all parts are completed, and it is affected by interior materials and surface textures. Affected by various factors, the darkroom lighting effect of a single component is not the same as the darkroom lighting effect of the whole vehicle, so the backlight color of each component often needs to go through multiple rounds of single piece evaluation and real vehicle evaluation.

Embodiment 1

[0035] Such as figure 1 As shown, an on-vehicle backlight evaluation system applied to vehicle backlight color evaluation of the present invention has three major components: a color-changing LED sample (that is, a backlight sample), a programmable controller, and a host computer. Among them, the backlight sample needs to be redeveloped on the basis of the original parts of the whole vehicle (such as air-conditioning panels, instruments, window switches, etc.), and all the backlight LED lights in it should be replaced with system-specific RGB LEDs. Then use the programmable controller to control the RGB LED of the backlight sample.

[0036] The programmable controller in the present invention needs to have central processing unit MCU; RGB LED driving circuit; two sets of PWM driving chips; RS485 serial communication chip; and other necessary peripheral electronic components. The schematic diagram of the programmable controller is as follows figure 2 shown in .

Embodiment 2

[0042] On the basis of the foregoing embodiments, the present invention can be extended to another embodiment:

[0043] After the backlight review is over, the color scheme of all backlight samples will be finalized. In order to allow component suppliers to provide components that meet the requirements of the car factory, the car factory needs to provide certain color samples for the manufacturer to compare and design. The invention is being completed image 3 After the review process, the RGB waveform duty cycle parameters can be solidified on the programmable controller through the host computer. The specific steps are:

[0044] 1). The upper computer enters the curing parameter interface

[0045]2). Select the "current parameter" option at the parameter input port;

[0046] 3). Confirm curing;

[0047] 4). After the programmable controller receives the curing command from the host computer, it saves the PWM chip address and the RGB waveform duty ratio parameters to the...

Abstract

The invention discloses a vehicle-mounted backlight evaluation system and method applied to whole-vehicle backlight color evaluation. The system comprises a backlight sample piece, an upper computer and a controller, the backlight sample piece is used for an actual vehicle to carry and is identical with actual parts in carrying mode, RGB LEDs are embedded inside the backlight sample piece, the upper computer is used for sending a light changing order, and the controller is used for communicating with the upper computer, receiving the light changing order and driving the RGB LEDs in the backlight sample piece to change light after receiving the light changing order. By applying the system, specially-made backlight sample pieces which can be mounted on vehicles can be developed efficiently at low cost to build evaluation environment suitable for actual vehicle environment, so that project node of whole-vehicle backlight color evaluation activity is brought forward greatly, and evaluation efficiency and evaluation quality are improved.

Description

technical field [0001] The invention relates to a vehicle-mounted backlight evaluation system and method applied to the evaluation of the color of the entire vehicle's backlight. Background technique [0002] With the rapid development of new vehicle technologies, people have higher and higher requirements for the interior effect of the vehicle, so the interior backlight effect in dim light has also become the design focus of major vehicle manufacturers. The different lighting colors can directly give users a diversified ride experience, improve the attractiveness of the interior, and increase market competitiveness at the same time. [0003] However, a complete car is composed of multiple parts and systems, and the design and production of these parts are in charge of different teams and different engineers. Therefore, the review of the backlight color of the vehicle interior needs to coordinate multiple suppliers to jointly produce color samples for vehicle review. Howev...
