Can signal processing unit in control device, arrests the message of the corresponding can of locking key on the key change, through information processing
Afterwards, can message processing module will process after information transfer in mcu, mcu receive this go here and there corresponding can message when,
Then cause corresponding actions by writing corresponding programmed instruction, mcu sending signal is transferred to led driver element, led driver element
Outside led can be driven accordingly.For different automobile types key lock former car car light flashing state different, this device
The outside led that internal processes can drive makes and former car synchronous flashing action.
2), remote controlled unlocking key.Principle is different with remote controlled locking key, only can message, and led synchronous flashing action occurs corresponding
Change.
3), steering indicating light synchronous flashing function.Principle is consistent with top description, will not be described here.When left-hand rotation opened by former car
Switch, led drive module can drive the led on the left side to allow led follow the left-hand rotation lamp flicker frequency flicker of former car.Turn right in the same manner.
4), hazard way light.When hazard way light switch opened by former car, led drive module can drive the led on both sides to follow
The flicker frequency flicker of the right and left warning lamp of former car.
5), lock prompting function.After former car stops working, master drives door switch action once, does not go up if detected after 5 seconds
Lock, mcu then sends information allows led drive module drive the led on both sides to flash 20 seconds.
In sum, the invention provides a kind of led control device, described led control device includes: mcu and led drives
Unit；After described mcu receives instruction, drive described led driver element to send instruction, control lighting and/or putting out of external led
Go out.In the technical scheme that the present invention provides, after mcu Single-chip Controlling processing module receives the related action message of former car, point
Analysis gained information simultaneously makes dependent instruction, and dependent instruction is sent to led driver element, controls lighting and/or putting out of external led
Go out.Whole regulation process, without the miscellaneous equipment of automobile, simple installation, applied range, solves band in prior art
The automobile side pedal of lamp, is primarily present and installs technological deficiency complicated and that range of application is narrow.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
