Description
Technical field
The present invention relates to Automobile Products, refer to especially a kind of intelligent windscreen wiper autonomous cruise speed system.
Background technology
Rain brush is a kind of instrument that carries out simple cleaning on power actuated vehicle car front glass in order to prevent rainwater and other pollutant effect sight lines.
Traditional batch (-type) rain brush, the sight line that rain brush speed can be driven according to rainfall impact divides three to level Four, to carry out manually adjusting by driver.Although becoming, more and more easily drives by present automobile, reliable.But drive the automobile of traditional rain brush, when advancing in the rain, the rain brush of also will diverting one's attention to adjust, the attention of having disperseed undoubtedly motorist, makes a strong impact for traffic safety.
Although some intelligent wiper can be realized automatic control function, trouble is installed, also need automobile circuit to adjust, the car owner who allows some have a mind to use hangs back.Domestic some intelligent rain brush controller, is not in fact real intellectuality, and they are only with speed of a motor vehicle hook, and the fast rain brush of car is fast, and the slow rain brush of car is slow, and car stops rain brush and stops.In fact this windshield-wiper controller is not realized intelligent, and only a kind of transitional product, can not reflect rainy truth, cannot realize automatic speed regulating function.
Summary of the invention
The present invention proposes a kind ofly automatically to control, speed of response is fast and control precisely safety and intelligent windshield wiper control system.
Technical scheme of the present invention is achieved in that
An intelligent wiper control system, comprising: capacitance electrode, detection chip, power supply and micro controller system; Capacitance electrode and detection chip are electrically connected, and power supply provides electric weight for rain brush autonomous cruise speed system; Detection chip and micro controller system are electrically connected.
Intelligent wiper control system provided by the invention, when rainwater reaches on capacitance electrode, electric capacity can change, and judges whether the size of rainfall and rainfall by the variation that detects it, and then the frequency that is started and started by Single-chip Controlling rain brush.By capacitance detecting principle, judge, judge more precisely, by data bus, detect, detection time is short.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the circuit block diagram of a kind of intelligent wiper control system of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
An intelligent wiper control system, comprising: capacitance electrode 1, detection chip 2, power supply 3 and micro controller system 4; Capacitance electrode 1 is electrically connected with detection chip 2, and power supply 3 provides electric weight for rain brush autonomous cruise speed system; Detection chip 2 is electrically connected with micro controller system 4.
Preferably, described detection chip 2 is electrically connected by serial ports (I2C) with described micro controller system 4, and it follows I2C bus protocol.
Preferably, described capacitance electrode 1 is provided with a plurality of check points.
Preferably, described detection chip 2 is electrically connected by data bus with described micro controller system 4, and data bus adopts I2C bus.
Preferably, described power supply 3 is automobile storage battery.
Preferably, described detection chip 2 is sensor.
Preferably, also comprise rain brush drive control module 5, described rain brush drive control module 5 is electrically connected with described micro controller system 4.
Preferably, intelligent wiper control system provided by the invention, when rainwater is got on capacitance electrode, the capacitance of cond will change, and capacitance electrode annex is provided with a plurality of check points, therefore detection chip Detection capacitance changes, and it is more accurate for what detect, therefore detection chip also can arrange a plurality of, the signal that detection chip detects sends micro controller system to by data bus, micro controller system can judge the value of the detection classification scheme corresponding with default amount of rainfall and the changing value of electric capacity, thereby judge the size of amount of rainfall, light rain or moderate rain or heavy rain or extra torrential rain etc., and then control rain brush control driver module control rain brush and whether open, and the frequency of motion after opening, realizing intelligence controls automatically, and precisely fast speed reaction again.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
