As a kind of preferred embodiment, FLASH 20 is installed in the micro controller system 2, FLASH 20 can stand write operation 100,000 times, thereby the requirement according to the client writes different functional parameters, and along with the upgrading of vehicle, only need upgrading FLASH 20 interior corresponding softwares, just go for various new vehicles.In the FLASH 20 the code protection memory space is arranged in addition, can't crack and read internal code without permission, strengthened the difficulty that illegal manufacturer copys.
As a kind of preferred embodiment, described control system of automobile flashing unit also comprises the overload short circuit detection module 9 that is electrically connected with micro controller system 2.The trailer quality is very different now; part car load factory is not owing to there is car load strand design ability; the wire harness that they adopt is contracted out to some small-sized wire harness factories together with design; these little factories cause bunch product second-rate owing to generally lack quality management and control ability; it is unreasonable on the car load layout to add wire harness; lack again the actv. safeguard procedures; a lot of trailer wire harness are with low quality; electric wire lacks the actv. safety method; just there is short-circuit conditions the wire harness that has in itself; what have is given a shock in the process of moving; friction makes wire outer skin gall bonding, causes short circuit, thereby burns the flashing light unit controller.And car load in actual use, a lot of users are owing to think that trailer lamp dress originally very little, bright not, they just to trailer arbitrarily reequip, wiring adds lamp, load is considerably beyond the power designs index of the actual reservation of flash controller, and it is aging to cause product to accelerate, the lost of life, even because increase the trailer bulb, cause overload and burn flashing light unit.Increased product short circuit overload detection module 9 in this programme, in case similar fault occurs, the flashing light unit control system is with automatic alarm and quit work.In the reality, in order to protect more accurately flashing light unit, this overload short circuit detection module 9 comprises main car flashing light unit overload short circuit detection module and trailer flashing unit overload short circuit detection module, and after short circuit, overload were got rid of, flashing light unit was resumed work automatically.
As a kind of preferred embodiment, described control system of automobile flashing unit also comprises the alarm module 10 that is electrically connected with described micro controller system 2.This alarm module 10 is installed in the operator's compartment, comprises four meter lamp driving circuits; When chaufeur startup flashing light unit control system was carried out routine inspection, testing result showed chaufeur by this alarm module 10.
Control system of automobile flashing unit principle of work of the present invention:
When micro controller system 2 detects the pole changer closure, just to export square-wave signal driving relay and do periodic adhesive, disconnection, steering indicating light is just normal flicker under the control of relay.Micro controller system 2 detects following signal when sending control square wave makes steering indicating light flicker work: the short-circuit signal of each steering indicating light, overload signal, fall modulating signal, left/right rotation to on-off signal, trailer signal.
Current detection module 5 gathers the working current of steering indicating light, convert this working current to small electric pressure drop signal by constantan wire, micro controller system 2 detects and converts to digital signal to this pressure drop signal, go forward side by side line number according to one's analysis, judge whether steering indicating light exists short circuit, transships or fall the phenomenon of the failure of lamp, if a certain road steering indicating light exists short circuit or overload, then micro controller system 2 drives corresponding relay disconnection, then corresponding steering indicating light (fault side) stops output, steering indicating light and the indicator lamp of trouble free side still work, the indicator lamp Chang Liang of overload or short circuit; Treat trouble free, after the lamp flicker 10 times, relay is adhesive again, and current detection module 5 detects again, if overload (short circuit) recovery, steering indicating light restores electricity.
If lamp appears falling in a certain road steering indicating light, then micro controller system 2 will drive warning 10, makes the meter lamp doubling frequency flicker of warning 10, and this road steering indicating light of prompting chaufeur falls lamp.
When trailer detection module 4 detected the trailer both sides and all do not have lamp, micro controller system 2 thought that without trailer the left and right trailer that just drives warning 10 turns to meter lamp to extinguish, and did not have trailer with the prompting chaufeur.
Technology and performance figure explanation:
Main car normal power 63W(21W*3), when current detection module 5 and voltage detecting mould 7 detected (or a plurality of) bulb, alarm module 10 is reported to the police: the king light flicker frequency was constant, and the indicating fault modulation frequency is fast again.When surpassing the 85W load (containing short circuit), main car (fault side) steering indicating light stops output, and steering indicating light and the indicator lamp of trouble free side still work, the indicator lamp Chang Liang of overload or short circuit.Treat trouble free, after the lamp flicker 10 times, relay is adhesive again, detects, if overload (short circuit) recovers, steering indicating light restores electricity.
When trailer detection module 4 detected trailer power less than 3W, indication warning module 10 is reported to the police: the king light flicker frequency was constant, and the indicator lamp frequency is fast again.When surpassing the 85W load (containing short circuit), trailer steering indicating light (fault side) stops output, and steering indicating light and the indicator lamp of trouble free side still work, the indicator lamp Chang Liang of overload or short circuit.Treat trouble free, after the lamp flicker 10 times, relay is adhesive again, and trailer detection module 4 detects, if overload (short circuit) recovers, steering indicating light restores electricity.
During monolateral turning to, main car relay and trailer relay glimmer frequency 85C/M simultaneously; But main car and trailer independent detection, independent control;
When left and right sides trailer disconnected simultaneously, flashing light unit judged that trailer breaks away from main car, and the trailer indicator lamp does not work when turning to.
Control system of automobile flashing unit of the present invention, can effectively detect in real time, quick and easy operating temperature, working current and the operating voltage of this flashing light unit and the coupled condition of judging trailer, make chaufeur can judge more accurately the mode of operation of flashing light unit; Have following functional characteristics:
1, has short circuit, overload protection function, when short circuit, overload are resumed work after getting rid of automatically;
2, have the trailer real-time detection function, but dismantle, install all hot line jobs of trailer, need not power-off restarting;
3, short circuit, overload, trailer, bulb malfunction are real-time detection, carry out real-time fault detection, indication;
4, reserve the CAN bus interface, the development that detects, controls to adapt to following entire automobile electric system.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
