Description
Technical field
The present invention relates to Control of Electric Vehicles technical field, particularly a kind of combination instrument backlight illumination automatic adjusument system
System.
Background technology
With the constantly improve of China's infrastructure construction, the tunnel quantity built up in city and on highway constantly increases
It is more.When driver enters or leaves tunnel, due to the acute variation of environment illumination intensity, often produce and adjust in-car
The demand of instrument backlight illumination.
Current vehicular meter backlight illumination both domestic and external needs user to be adjusted manually according to demand, often to find instrument
Brightness regulation interface in the menu of table backstage, then carries button or steering wheel speed dial key by operating instrument and realizes.It is this
Regulative mode is time-consuming and laborious, especially can bring the undesirable driving of driver when driving in mountain area section frequent access tunnel
Experience, while reading of the driver for instrument board important content is had an effect on, there is some potential safety problems.
The content of the invention
It is an object of the invention to provide a kind of instrument to adjust the backlight illumination of itself based on extraneous intensity of illumination,
So as to efficiently solve the combination instrument backlight illumination self-adaption regulation system of driver's puzzlement.
For a kind of combination instrument backlight illumination self-adaption regulation system of the present invention, its technical solution is：
Sunlight rain sensor：For detecting the intensity of illumination of extraneous visible ray and infrared light, to extraneous intensity of illumination
Grade is demarcated, and will be sent to BCM according to strength grade signal by the ambient light of calibration；
BCM：Receive the ambient light by calibration that sunlight rain sensor is sent and shine strength grade signal, and periodically
It is sent to combination instrument；
Combination instrument：According to the ambient light received according to itself corresponding backlight illumination of strength grade signal behavior etc.
Level, the brightness regulation of instrument is combined according to itself backlight illumination grade.
More preferable, the sunlight rain sensor includes photodiode and infrared photodiode, described photosensitive
Diode is used for the intensity of illumination for detecting extraneous visible ray, and the infrared photodiode is used for the illumination for detecting extraneous infrared light
Intensity.
More preferable, the ambient light includes a grade, itself backlight illumination of the combination instrument according to strength grade
Grade includes b grade, and perceiving evaluation by real vehicle determines the combination instrument itself when extraneous intensity of illumination is in each grade
The optimal level of backlight illumination, perceives evaluation result the ambient light is bright according to strength grade and itself backlight according to the real vehicle
Degree grade is corresponded to.
More preferable, the sunlight rain sensor is connected by LIN lines with BCM.
More preferable, the BCM is connected by CAN lines with combination instrument.
The beneficial effects of the invention are as follows：Additional components need not be increased, communicated, possessed by LIN lines, CAN bus
The possibility of volume production.What it is due to the detection of sunlight rain sensor is real-time light intensity at front windshield, is had very high
Accuracy and real-time.After combination instrument is arranged to automatic adjustment backlight illumination pattern, instrument can be according to ambient lighting
Intensity voluntarily adjusts suitable backlight illumination grade, can operate regulation meter backlight level repeatedly manually to avoid driver,
Effectively reduce driving difficulty.
Brief description of the drawings
Fig. 1 is module catenation principle block diagram of the present invention；
Fig. 2 is control flow chart of the present invention；
In figure：1-sunlight rain sensor, 2-BCM, 3-combination instrument.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.The specific embodiments described herein are merely illustrative of the present invention, is not used to limit
The fixed present invention.In addition, as long as technical characteristic involved in each embodiment of invention described below is each other
Not forming conflict can be mutually combined.
As shown in Figure 1, a kind of combination instrument backlight illumination self-adaption regulation system includes sunlight rain sensor 1, BCM 2
With combination instrument (IC) 3.Wherein sunlight rain sensor 1 connected with BCM 2 by LIN lines, BCM 2 and combination instrument (IC) 3
Connected by CAN bus, and sunlight rain sensor 1 include be used for detect extraneous visible ray intensity of illumination photodiode and
For detecting the photodiode of extraneous infrared light.
As shown in Fig. 2, a kind of control flow of combination instrument backlight illumination self-adaption regulation system is as follows：
User can select manually or automatically shaping modes by steering wheel speed dial key, when user select automatic adjustment pattern it
Afterwards, instrument brightness automatic adjusument function is opened.In the process of moving, the sunlight rainfall being arranged on front windshield passes vehicle
Sensor 1 separately detects the intensity of illumination of extraneous visible ray and infrared light by photodiode and infrared photodiode.It is logical
Intensity of illumination can be divided into a grade by crossing real vehicle calibration, and a values are 10 in this example.Sunlight rain sensor is according to calibration
Result the grade point of extraneous intensity of illumination is sent to BCM 2 by LIN lines.
BCM 2 is after receiving the ambient light that sunlight rain sensor 1 sent by LIN lines and shining strength grade, by whole
Ambient light is periodically sent to combination instrument (IC) 3 by car CAN network according to strength grade.
The backlight illumination grade one of combination instrument (IC) 3 is divided into b grade, and value is 6 in this example.Developed in instrument
During evaluation perceived by calibration and real vehicle determine that instrument backlight illumination is most when extraneous intensity of illumination is in each grade
Good grade, thus by the b grade formation one-to-one corresponding pass of itself backlight illumination of a grade and instrument of extraneous intensity of illumination
System.Combination instrument (IC) 3, can basis after the numerical value for the extraneous backlight level signal a for receiving BCM 2 and being sent by CAN network
Calibration value selects the numerical value of itself corresponding backlight level b.The input of bonding position disk speed dial key, if unlatching has been selected in user
Instrument board backlight illumination automatic adjustment pattern, then instrument board backlight illumination grade adjusted accordingly according to the numerical value of b.
The above description is merely a specific embodiment, it is noted that any those skilled in the art exist
Disclosed herein technical scope in, the change or replacement that can readily occur in, should all cover protection scope of the present invention it
It is interior.
