As a kind of preferred embodiment, said automobile flashing light unit control system also comprises the overload short-circuit detecting module 9 that is electrically connected with micro controller system 2.Now the trailer quality is very different, and part car load factory is not owing to there is car load strand design ability, and the wire harness that they adopted is contracted out to some small-sized wire harness factories together with design; These little factories are owing to generally lack quality management and control ability and cause bunch product second-rate, and it is unreasonable on the car load layout to add wire harness, lacks the actv. safeguard procedures again; A lot of trailer wire harness are with low quality; Electric wire lacks the actv. safety method, and just there is short-circuit conditions the wire harness that has in itself, have be given a shock in the process of moving, rubbing makes wire outer skin gall bonding; Cause short circuit, thereby burn the flashing light unit controller.And car load in actual use, and a lot of users are owing to feeling trailer lamp dress originally very little, and are bright inadequately; 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 quicken, the lost of life; Even, cause overload and burn flashing light unit because increase the trailer bulb.Increased product short circuit overload detection module 9 in this programme, in case similar fault occurs, the flashing light unit control system is with auto alarm and quit work.In the reality, in order to protect flashing light unit more accurately, this overload short-circuit detecting module 9 comprises main car flashing light unit overload short-circuit detecting module and trailer flashing light unit overload short-circuit detecting module, and after short circuit, overload were got rid of, flashing light unit was resumed work automatically.
As a kind of preferred embodiment, said automobile flashing light unit control system also comprises the alarm module 10 that is electrically connected with said 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 through this alarm module 10.
Automobile flashing light unit control system 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 and right sides pole changer signal, trailer signal.
Current detection module 5 is gathered the working current of steering indicating light; Convert this working current to small electric pressure drop signal through constantan wire, micro controller system 2 detects and converts to digital signal to this pressure drop signal, the line data analysis of going forward side by side; 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 driving corresponding relays are broken off, and then corresponding steering indicating light (fault side) stops output; The steering indicating light of trouble free side and indicator lamp be normal operation still, overload or short circuited indicator lamp Chang Liang; Treat trouble free, after the lamp flicker 10 times, relay is adhesive once more, and current detection module 5 detects once more, 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 was thought no trailer, and the left and right trailer that just drives warning 10 turns to meter lamp to extinguish, and does not have trailer with the prompting chaufeur.
Technology and performance figure explanation:
When main car normal power 63W (21W*3), current detection module 5 detected (or a plurality of) bulb with voltage detecting mould 7, 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 the steering indicating light of trouble free side and indicator lamp be normal operation still, overload or short circuited indicator lamp Chang Liang.Treat trouble free, after the lamp flicker 10 times, relay is adhesive once more, detects, if overload (short circuit) recovers, steering indicating light restores electricity.
When trailer detection module 4 detected trailer power less than 3W, indication alarm 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 the steering indicating light of trouble free side and indicator lamp be normal operation still, overload or short circuited indicator lamp Chang Liang.Treat trouble free, after the lamp flicker 10 times, relay is adhesive once more, 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 broke off simultaneously, flashing light unit judged that trailer breaks away from main car, and the trailer indicator lamp does not work when turning to.
Automobile flashing light unit control system of the present invention; Can detect operating temperature, working current and the operating voltage of this flashing light unit and the coupled condition of judging trailer effectively in real time, quick and easy, make chaufeur can judge the mode of operation of flashing light unit more accurately; 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 fail and detect, indicate;
4, reserve the CAN EBI, to adapt to the development that following car load electric system detects, controls.
The above embodiment has only expressed several kinds of embodiments 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 under the prerequisite that does not break away from the present invention's design, 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 accompanying claims.
