In figure, 1. insure 2. wiper combined switches.
The specific embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described further.
This rainy motor synchronous control system of scraping, comprise the key switch that is connected in storage battery, be connected in the open type relay of key switch, ECU, closed type relay I, closed type relay II, closed type relay III, closed type relay IV, wiper combined switch 2, main rain shaving electrical machine and secondary rain shaving electrical machine, described ECU, wiper combined switch 2 all is connected in open type relay closed type relay I, closed type relay II, closed type relay III and closed type relay IV are connected to open type relay and ECU, described main rain shaving electrical machine and secondary rain shaving electrical machine are connected to closed type relay I, closed type relay II, closed type relay III, closed type relay IV and wiper combined switch 2.After vehicle utilizes key to open switch, the adhesive of open type relay, storage battery is powered to windscreen wiper system by the open type relay.When wiper combined switch 2 is opened intermittently shelves, wiper combined switch 2 sends to ECU by signal, ECU receives instruction rear drive closed type relay I, the synchronous intermittent adhesive of closed type relay II, positive current accesses respectively the low gear pin of main rain shaving electrical machine and secondary rain shaving electrical machine by two relays, because ECU controls the adhesive at intermittence of controlling closed type relay I, closed type relay II simultaneously, therefore main rain shaving electrical machine and secondary rain shaving electrical machine can complete the intermittently working process of shelves.
When wiper combined switch 2 is opened low gear, wiper combined switch 2 sends to ECU by signal, ECU receives instruction rear drive closed type relay I, the synchronous adhesive of closed type relay II, positive current accesses respectively the low gear pin of main rain shaving electrical machine and secondary rain shaving electrical machine by closed type relay I, closed type relay II, main rain shaving electrical machine and secondary rain shaving electrical machine can complete the working process of low speed.
When wiper combined switch 2 is opened high speed gear, positive voltage directly accesses the high speed gear pin of main rain shaving electrical machine and secondary rain shaving electrical machine simultaneously by wiper combined switch 2, closed type relay III and closed type relay IV adhesive simultaneously simultaneously, stop the reset signal loop to produce, rain shaving electrical machine just can complete the working process of high speed gear like this.
When wiper combined switch 2 cuts out, if main rain shaving electrical machine and secondary rain shaving electrical machine be not in the return state, now the automatic reset device in motor is used the electric current pin to engage with the reset signal pin, closed type relay I, closed type relay II, closed type relay III, closed type relay IV are all in normally open simultaneously, circuit can form loop, control main rain shaving electrical machine and secondary rain shaving electrical machine is rotated further, finish until turn to the return position.
When windscreen wiper spray shelves are opened, ECU, according to the wiper combined switch length of 2 crawl times, controls the output of ECU, makes 1-3 circulation of main rain shaving electrical machine and secondary rain shaving electrical machine work, according to the number of cycles of main rain shaving electrical machine return signal judgement rain shaving electrical machine.Because windscreen wiper working cycle number after spray is less, the phase difference of two motors can be not too many, therefore only with the return signal of main motor, judges.
The insurance 1 that is connected to key switch and open type relay by increasing by two ends can prevent the generation of the excessive circuit burnout situation caused of electric current, has further ensured this rainy safety of scraping motor synchronous control system.
