Specific embodiment
Specifically illustrate embodiments of the present invention with reference to the accompanying drawing, attached drawing is only for reference and illustrates use, does not constitute pair
The limitation of the invention patent protection scope.
On the one hand the embodiment of the present invention provides a kind of instrument method for controlling backlight thereof, comprising:
Whether each parameter that step 1, detection instrument are shown is normal, judges whether instrument backlight is in the open state.
Each parameter that automobile instrument is shown mainly includes numerical value class and prompt warning class, and numerical value class includes speed, revolving speed, hair
Motivation water temperature, oil mass etc., prompting warning class includes that car door does not close alarm, engine failure alarm, ABS-system fault alarm etc..Having
When body is implemented, by normality threshold range and mutual relationship (such as the pass between revolving speed and speed that each parameter is arranged
System) it is whether normal come each parameter for judging that instrument is shown.
The backlight of virtual instrument uses LED backlight at present, by PWM control mode, therefore can be by detecting PWM waveform
To judge whether backlight is in the open state.
If each parameter that step 2, instrument are shown is normal, instrument backlight open, perform the next step；If instrument is shown each
Parameter is normal, instrument backlight is closed, then does not execute any operation.
Step 3 closes instrument backlight after the first preset time.
If each parameter that instrument is shown is normal, then the parameter that user need not pay close attention to instrument is shown, if instrument backlight is in
Open state then can close instrument backlight in the first preset time (such as 10 seconds) afterwards, avoid the interference to sight；If instrument
Table backlight is in close state, then can continue to remain off, play energy saving effect.
If abnormal parameters, instrument backlight open that step 4, at least one instrument are shown, then follow the steps 6；If at least one
Abnormal parameters that instrument show, the closing of instrument backlight, then perform the next step.
Step 5, detection ambient enviroment brightness, and it is bright according to preset relation formula instrument backlight illumination to be adjusted to target
Degree.
If the abnormal parameters that instrument is shown, user should be paid close attention to, if instrument backlight is in close state at this time,
Ambient enviroment brightness should be then detected first, and instrument backlight illumination is adjusted to by object brightness according to preset relation formula, avoided
Backlight illumination discomfort interferes safe driving.
In the specific implementation, instrument backlight LED is driven using constant current, and the brightness of LED and electric current are linear.
Specifically, the relational expression of instrument backlight illumination and ambient enviroment brightness are as follows:
L=α * [10lg (β/γ)+26]/100
Wherein, L indicates that instrument backlight illumination, α are a constant, and β is environmental light brightness, and γ is the transmitting system of apparatus glass
Number.
The exception level for the abnormal parameters item that step 6, detection instrument are shown, if the exception level is greater than default exception
Value then keeps instrument backlight open until abnormal removing, otherwise performs the next step.
The abnormal parameters item that some instrument are shown is general issues, such as oil mass is too low, and some exception items then will lead to
Safety problem, such as ABS-system fault, therefore, it is necessary to the exception levels of the abnormal parameters item shown according to instrument to determine that instrument is carried on the back
The open and close of light.When exception level is greater than default exceptional value, the abnormal parameters item for illustrating that instrument is shown will lead to safety
Problem needs user to pay special attention to, therefore keeps instrument backlight open until abnormal remove.
Step 7 closes instrument backlight after the second preset time.
Second preset time is greater than the first preset time, such as 1 minute.
In one embodiment of the invention, after step 2, before step 3 further include:
Step 21 issues the prompt information for closing instrument backlight, does not close if receiving confirmation in third preset time
The information of backlight then keeps backlight open, otherwise performs the next step.
In some cases, user wish keep instrument backlight open, when system in third preset time (can be less than or
Equal to the first preset time, such as 9 seconds) it receives confirmation and does not close the information of backlight, such as phonetic order, press key control signal
Deng then keeping instrument backlight open.
In one embodiment of the invention, after step 21 further include:
Step 22 broadcasts each parameter that instrument is shown.
When closing instrument backlight, each parameter that instrument is shown is broadcasted, such as speed 80km/h, engine 5000
Rev/min, 100 liters of oil mass, etc., so that user understands the basic status of current vehicle.
In one embodiment of the invention, after step 7 further include:
Step 8 obtains abnormal parameters item and current vehicle position information that instrument is shown, searches the ginseng that the instrument is shown
The maintenace point of number exception item executes step 5 when vehicle is less than pre-determined distance at a distance from the maintenace point.
By obtaining the abnormal parameters item and current vehicle position information that instrument is shown, by local or server
The maintenace point for searching the abnormal parameters item that the instrument is shown, when vehicle is less than pre-determined distance at a distance from the maintenace point,
Instrument backlight is opened, user is prompted to repair.
As shown in Figure 1, another aspect of the present invention provides a kind of instrument backlight control apparatus, including meter parameter reads mould
Block, meter parameter judgment module, exception information module, backlight state judgment module, Timer module, ambient light detection module,
Backlight control module；
