The induction type windscreen wiper water-spraying system comprises the windscreen wiper, a rain sensor, a humidity sensor, a body control module (BCM) and a water spraying motor, wherein the windscreen wiper, the rain sensor, the water spraying motor and the humidity sensor are connected with the BCM, and the BCM can receive control signals of the remote control of the automobile door lock.
Description
Technical field
The utility model relates to a kind of automotive electronic technology, relates in particular to a kind of induction type windscreen wiper water-injection system for automobile.
Background technology
At the larger weather of humidity ratio, often shrouding the globule and fog on the Windshield, affect driver's sight line.This moment, chaufeur need to be opened ignition lock, opened wiper switch again, wiper work, and it is clean that glass just becomes.Equally, chaufeur needed manual unlocking wiper switch when vehicle travelled in the rainy day, often adjusted the wiper gear according to rainfall, had not only bothered but also affected normal driving.Automatic windshield wiper has also appearred in the prior art, because the advantages such as the optics rain sensor has long service life, induction is sensitive, cost is low, easy installation, so all use the optics rain sensor to start control as wiper, its shortcoming is that the optics rain sensor is subject to the interference such as dust, earth, insect and leaf and misoperation very easily occurs, not only waste energy, and have a strong impact on the service life of wiper (rain shaving blade).Such as open day be on 04 09th, 2008, publication number is that the patent documentation of CN101158652A discloses such technical scheme, a kind of Vehicular automatic wiping system, it has rain sensor and wiper controller, rain sensor utilizes the optical principle rainfall information collection and by sensing circuit signal is transformed and pass to wiper controller, wiper controller control rain shaving electrical machine drives the rain shaving blade running, rain sensor has the optical mirror slip for induction rainfall size, is provided with 8 light transmitting mirrors on the optical mirror slip, 8 light-receiving camera lenses, the aspherical surface type eyeglass of optical mirror slip for being made by makrolon material.Sensing circuit comprises input and output driving circuit, pulse modulated circuit, the emission of LED light and acceptor circuit, also has active band-pass filter, amplifier and voltage controlled oscillator (VCO).8 optical pickocffs still can not solve the interference such as dust, earth, insect and leaf on the optical mirror slip of this scheme, and the above-mentioned chaff interference on Windshield can make rain sensor send spurious signal and drive the wiper misoperation.
Summary of the invention
The utility model mainly be solve the existing wiper open operation of prior art inconvenient, easily be disturbed technical matterss such as misoperation occur, a kind of induction type windscreen wiper water-injection system is provided, at rainy day or the too heavy weather of humidity, press remote controller door lock unlock switch, windscreen wiper system is opened automatically, scrapes off rainwater on glass or fog, make the driver into the car, without any need for operation, just can the scraping Windshield, misoperation can not occur at Windshield during without steam, the globule yet.
The utility model is mainly solved by following technical proposals for the prior art problem, a kind of induction type windscreen wiper water-injection system, comprise wiper, rain sensor, humidity sensor, car body controller (BCM), water spray motor, wherein wiper, rain sensor, water spray motor are connected car body controller with humidity sensor, and car body controller receives the control signal of Door Lock remote controller.
Here, after chaufeur sends remote controller door lock unlocking signal, humidity sensor inspection vehicle outer air humidity, whether rain sensor detects to rain and reaches rainfall, when air humidity reaches more greatly specified value and rain sensor and also reaches the regulation detected value, car body controller (BCM) drives wiper and starts working, scrape gear 3 times, again detect, if rain sensor still detects regulation rainfall value, then by regulate the speed automatic scraping gear of setting value, during constantly detect rainfall, set when stopping to be worth until the detected value of rain sensor reaches, stop to scrape gear; Car body controller (BCM) is after receiving remote controller door lock unlocking signal, if it is larger to detect air humidity, when the rainfall detection value was too small, car body controller (BCM) drove the water spray motor, water spray 1S, and wiper is scraped gear 3 times; Minimum when the air humidity sensor detected value, and the rain sensor detected value has illustrated chaff interference on Windshield when large, and car body controller (BCM) drives the water spray motor, water spray 1S, and wiper is scraped gear 3 times, and wiper quits work afterwards.
This windscreen wiper water-injection system was in the stand-by operation state always before receiving door lock locked remote control signal, be closed condition after receiving door lock locked remote control signal.
As preferably, humidity sensor is Linear voltage output formula Integrated Humidity Sensor, and rain sensor is the optical profile type rain sensor.Linear voltage output formula Integrated Humidity Sensor can be exported the volt magnitude voltage signals that is proportionate relationship with relative humidity, fast response time, and good reproducibility, contamination resistance is strong; The outstanding advantages such as the optical profile type rain sensor has long service life, induction is sensitive, cost is low, easy installation.
As preferably, humidity sensor is installed in outside the car.Such as being installed in the front windshield lower edge, respond to car outer air humidity.
As preferably, wiper comprises rain shaving electrical machine, Windshield Wiper, and rain shaving electrical machine connects car body controller (BCM), and rain shaving electrical machine drives Windshield Wiper.Car body controller (BCM) drives rain shaving electrical machine and drives Windshield Wiper work.
As preferably, when the Humidity Detection value is large, rainfall detection value hour, car body controller drives the water spray motor, sprays water for 1 second, and wiper is scraped gear 3 times.Although when air humidity more greatly but is rained, scrape gear several times behind the water spray first, wiper quits work afterwards again.
The beneficial effect that the utility model brings is at rainy day or the too heavy weather of humidity, to press remote controller door lock unlock switch, windscreen wiper system is opened automatically, scrapes off rainwater on glass or fog, makes the driver into the car, without any need for operation, just can the scraping Windshield; When raining according to rainfall by the setting wiper automatic scraping gear of regulating the speed; When just high humidity does not rain, spray water first and scrape again gear; Misoperation can not occur at Windshield during without steam, rainwater; Energy savings, prolong swept area of wiper blade service life.
Description of drawings
Fig. 1 is a kind of functional block diagram of the present utility model.
Among the figure: the 1st, gate lock remote control, the 2nd, receiving wire, the 3rd, humidity sensor, the 4th, rain sensor, the 5th, car body controller, the 6th, water spray motor, the 7th, rain shaving electrical machine, the 8th, Windshield Wiper.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1, the utility model is a kind of induction type windscreen wiper water-injection system, and car body controller (BCM) 5 connects humidity sensor 3, rain sensor 4, water spray motor 6, rain shaving electrical machine 7, receiving wire 2.
