Further, the brightness regulating switch module includes that brightness increases switch and brightness reduction switch.
Further, the left side with the instrument board of driver's face is arranged in the brightness regulating switch module.
The utility model has the advantages that a kind of brightness of backlight regulating system of switch for vehicle of the utility model, adopts
With the existing hardware device of vehicle, it only need to additionally increase the luminance adjustment module, the backlight to switch for vehicle can be realized
Brightness regulation, adapt to the sense organ of different drivers, reach optimum efficiency, hardware cost is low.The utility model also provides simultaneously
A kind of backlight brightness regulation method of switch for vehicle, can be realized and vehicle brightness of backlight is adjusted, and adapts to difference and drives
The sense organ for the person of sailing reaches optimum efficiency, simple to operate.
Detailed description of the invention
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the schematic diagram of brightness of backlight regulating system described in the utility model.
Specific embodiment
Refering to Figure 1, the utility model provides a kind of brightness of backlight regulating system of switch for vehicle, including BCM
Car body control module, brightness regulating switch module and the instrument control connected with the driving chip of backlight by CAN bus
Module；The BCM car body control module is connected to the brightness regulating switch module, the BCM Body Control by LIN line
Module is connected to the instrument control module by CAN bus.By the existing hardware device of vehicle itself, need to only increase described
The brightness of backlight adjusting to switch for vehicle can be realized, so that hardware cost is low in brightness regulating switch module.
Regulative mode: the backlight of switch for vehicle is opened, and driver operates the brightness regulating switch module, the brightness
Regulating switch module increaseds or decreases signal according to the operation of driver sending brightness and gives BCM car body control module, the BCM
Brightness is increasedd or decreased signal again and is transmitted to instrument control module by car body control module, and the instrument control module passes through brightness
Signal Regulation brightness of backlight percentage signal is increasedd or decreased, the brightness hundred after then the instrument control module will regulate
Divide the controller for being sent to backlight by CAN bus than signal, the controller of backlight is adjusted according to brightness percentage signal
The driving current of backlight, it is finally that the brightness regulation of backlight is good, to realize that different drivers, will according to respective sense organ
The brightness regulation of backlight reaches best sensory effects to optimal brightness.For example, in specific implementation, brightness percentage signal
Is defined as: normal brightness value is 700CD/m2 (100%), range: 0% (0x 0) to 100% (0x 64)；Accuracy: 1%；Letter
Number title: METER_BackgroundLight_Level_Value.In a specific embodiment, the driving chip of backlight
Model TPOWER TP8203 13311X.
In specific implementation, a preferred embodiment: the backlight is LED light.
The LED light has a plurality of, the different switches of corresponding vehicle, the driving chip and LED light of a plurality of LED light
Model it is consistent, guarantee the brightness of each LED light, the consistency of coloration, avoid the difference of light light, further
Sensory effects are enabled to reach optimum efficiency.
The brightness regulating switch module is touch panel switch module, using the switching mode of touch, so that operation is more
Easily, simply.
The brightness regulating switch module includes that brightness increases switch and brightness reduction switch, is opened by the brightness increase
Brightness can be increased by brightness number has been previously set for the brightness of backlight by closing, and reducing switch by the brightness can will carry on the back
The brightness of light lamp reduces brightness by brightness number has been previously set, and two Operation switches are arranged, so that more convenient operation, simple.
Such as: the brightness, which increases switch and brightness, reduces switch, respectively corresponds and is provided with several gears, the corresponding brightness of each gear
Percentage is 10%, i.e., each gear is corresponding to increase by 10% or reduction by 10%.
The left side with the instrument board of driver's face is arranged in the brightness regulating switch module, so that the brightness regulation
Switch module is close with a distance from driver, facilitates operation, does not influence to drive vehicle, guarantees driving safety.
A kind of adjusting method of the brightness of backlight of switch for vehicle of the utility model, comprising the following steps:
Step S1, the backlight of switch for vehicle is opened, and driver operates brightness regulating switch module；
Step S2, the described brightness regulating switch module according to the operation of driver issue brightness increased or decrease signal to
BCM car body control module；
Step S3, brightness is increasedd or decreased signal again and is transmitted to instrument control module by the described BCM car body control module；
Step S4, the described instrument control module increaseds or decreases Signal Regulation brightness of backlight percentage letter by brightness
Number, the brightness percentage signal after then the instrument control module will regulate is sent to the control of backlight by CAN bus
Device processed；
Step S5, the controller of backlight adjusts the driving current of backlight according to brightness percentage signal, finally will back
The brightness regulation of light lamp is good.
To realize that different drivers reach the brightness regulation of backlight to optimal brightness most according to respective sense organ
Good sensory effects.
Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model
