It is following that its discontinuous is scraped the water process: dial when scraping the water retaining intermittence when the windscreen wiper combined switch, described intermittence is scraped water drain cock mouth I and is obtained high flat signal, and the coil of controlling first relay K 1 gets the electric closing of contact that makes; The fast switch mouth 53M of described rain shaving electrical machine two retainings sends control and scrapes water and instruct to rain shaving electrical machine, and described rain shaving electrical machine control windscreen wiper begins to scrape water, scrape water one circle after; Rain shaving electrical machine playback signal port breaks off the contact of first relay K 1; Get into intermittent time, control capacitance C2 discharged after control chip U7 detected this signal, after discharge is accomplished; First relay K, 1 coil once more the electric contact that makes is closed once more, carry out the next windscreen wiper cycle;
It is following that the water process is scraped in described washing: when the cleaning scraper water drain cock is closed, wash switch mouth T obtains high flat signal, control chip U7 control cleaning motor water spray; Simultaneously, control capacitance C2 begins charging, behind about 600ms; When capacitor C 2 charging valtages were higher than the comparative figure of control chip U7 setting, control chip U7 controlled first relay K, 1 coil electricity and makes the closing of contact, and the fast switch mouth 53M transmission of described rain shaving electrical machine two retainings control is scraped water and instructed to rain shaving electrical machine; Described rain shaving electrical machine control windscreen wiper begins to scrape water; Simultaneously, capacitor C 2 begins discharge, when its voltage is lower than the comparative figure of control chip U7 setting; Described control chip U7 controls first relay K, 1 contact open, interior during this period of time rain shaving electrical machine running 2-3 circle.
Described fog tail lamp control and executive module 3 comprises second relay K 3, the first aerotron Q1 and the second aerotron Q2; The two ends, contact of described second relay K 3 are connected with the second storage battery mouth 30, fog tail lamp signal port 87 respectively; The collecting electrode of the base stage of the described first aerotron Q1, the second aerotron Q2 is connected with control chip U7 respectively; The emitter of the emitter of the described first aerotron Q1, the second aerotron Q2 is connected on the coil two ends of second relay K 3 respectively; The base stage of the described second aerotron Q2 is connected with fog tail lamp switch mouth E; The emitter of the described second aerotron Q2 is connected with adverse-weather lamp signal port F, head light signal port 15a respectively, the grounded collector of the described first aerotron Q1;
When described adverse-weather lamp signal port F and head light signal port 15a are low level, the contact open of described second relay K 3; When described adverse-weather lamp signal port F and head light signal port 15a have at least one to be in high level; When if described fog tail lamp switch mouth E is high level; The closing of contact of second relay K 3 is exported high level and is lighted for fog tail lamp signal port 87 control fog tail lamps; When if described fog tail lamp switch mouth E is low level, the contact open of described second relay K 3 comes output low level to extinguish for fog tail lamp signal port 87 control fog tail lamps.
Situation one under the situation that does not have the input of head light signal and adverse-weather lamp signal because control chip U7 not electric, can not make 3 adhesives of second relay K even import the fog tail lamp on-off signal, so fog tail lamp can't be worked.That is to say that the fog tail lamp switch can't be controlled fog tail lamp separately under the situation that head light or adverse-weather lamp are not opened.
Situation two is under the situation of head light or the input of adverse-weather lamp signal; If there is not the input of fog tail lamp on-off signal, the second aerotron Q2 collecting electrode and base stage are idiostatic so, and the second aerotron Q2 is in by state; So the CK2 pin of control chip is in low level state; Control chip can't make the first aerotron Q1 saturated, and second relay can not adhesive, and fog tail lamp can't be worked.Just head light or adverse-weather lamp any one all can not the direct control fog tail lamp work.
Situation three, four is under the situation of head light or the input of adverse-weather lamp signal; And closed fog tail lamp switch, the second aerotron Q2 is saturated so, and the K2 pin of control chip is in high level state; And it is saturated to drive the first aerotron Q1, and the second relay adhesive fog tail lamp gets the electrician and does.Just when adverse-weather lamp, head light signal at least one when effective, control chip gets electric, the fog tail lamp switch could be controlled fog tail lamp.
Situation five is under the situation that head light and adverse-weather lamp are imported simultaneously, and control chip gets electric, and the fog tail lamp switch can be controlled the fog tail lamp normal operation equally.
Sum up the principle of work of fog tail lamp according to above five kinds of situations: head light extinguishes, and during front fog lamp lighting, the break-make of fog tail lamp is controlled by the fog tail lamp switch; Head light is lighted, and when adverse-weather lamp extinguished, the break-make of fog tail lamp was controlled by the fog tail lamp switch also; When head light, adverse-weather lamp were all opened, the fog tail lamp switch is the break-make of may command fog tail lamp also; After fog tail lamp was opened, when head light, adverse-weather lamp were all closed, fog tail lamp also extinguished.
Described steering indicating light control and executive module 4 comprises the 3rd relay K 2; The two ends, contact of described the 3rd relay K 3 are connected with the first storage battery mouth 49, turn signal swich mouth 49a respectively, and the coil two ends of described the 3rd relay K 3 and turn signal swich mouth 49a are connected on respectively on the control chip U7;
When described turn signal swich is moved, through the turn signal swich mouth control chip U7 is connected with the external modulation load, the voltage that makes control chip U7 internal comparator is less than the reference voltage of setting, and described control chip U7 controls intermittently break-make of the 3rd relay.
When turn signal swich was dialled left (right side), the external modulation load branch of Access Control chip had accounted for the voltage of original circuit, and the voltage that causes input control chip internal comparator is less than original 5V reference voltage.At this moment control chip will make relay with 50% empty accounting break-make intermittently.The steering indicating light flicker work of a final side turns to indication to play.
Side steering indicating light installed when being linked into this circuit simultaneously two when the double jump light switch, the steering indicating light that control chip will drive both sides in the same way glimmers work simultaneously to play the alarm indication.
When certain turning indicator open circuit of vehicle, sampled voltage feeds back to the comparator of chip internal, if be higher than the reference voltage of 81mV, and the doubling frequency of impulse deviser so, steering indicating light begins malfunctioning alarm.
