Abstract
The invention discloses an anti-fogging method for an automotive front windshield. According to the method, a first temperature sensor and a humidity sensor are arranged and used for sensing the temperature and humidity of the air outside an automobile; a second temperature sensor is arranged and used for sensing the temperature of an outer glass layer of the automotive front windshield; a third temperature sensor is arranged and used for sensing the temperature in the automobile; an outer heating layer and an inner heating layer are arranged and used for heating the outer glass layer and an inner glass layer of the automotive front windshield respectively. In the working process, firstly, the dew point temperature of the air outside the automobile is calculated according to the temperature and humidity of the air outside the automobile; if the temperature of the outer glass layer is lower than the dew point temperature, the outer heating layer is controlled to heat the outer glass layer; secondly, the temperature difference between the temperature of the air in the automobile and the temperature of the air outside the automobile is calculated; if the temperature difference is larger than or equal to a preset temperature difference threshold value, the inner heating layer is controlled to heat the inner glass layer. The anti-fogging method has the advantages that design is simple, use is convenient, whether the automotive front windshield will be misty can be judged automatically according to the environment, and demisting can be conducted automatically.
Description
Technical field
The present invention relates to vehicle electric field, particularly relate to a kind of method that automobile front windshield is antifog.
Background technology
Vehicle electronics is the general name of car body electronic control device for vehicle and vehicular automotive electronic control setup.Car body electronic control device for vehicle, comprises engine management system, chassis control system and electrical control unit system (body electronics ECU).The most notable feature of vehicle electronics advances to control systemization, with the electric-control system of sensor, microprocessor MPU, actr, tens of even up to a hundred electronic devices and components and parts thereof composition, just obtaining market extremely widely.Car body electronic control device for vehicle is just like human body that is bald-faced, that do not dress any clothing jewelry; Vehicular automotive electronic comprises vehicle information system, auto-navigation system and automotive entertainment system.Vehicular automotive electronic control setup is just like clothing, the jewelry of the person.
Automotive circuit diagram is considered to the revolution in automotive technology development process, and the degree of automotive circuit diagram is counted as the important symbol weighing modern automobile level, is used to develop new model, improves the most important technical measures of automotive performance.Automaker thinks that the quantity of increase vehicle electronics, promotion automotive circuit diagram are the important effective means capturing future automobile market.
According to statistics, from 1989 to 2000, the ratio that on average on each car, electronics package is shared in whole Automobile manufacturing cost increases to more than 23% by 16%.On some Pullman saloons, use the quantity of one chip microcomputer to reach 48, electronic product accounts for more than 50% of integral vehicle cost, and the application of current Eltec has almost been deep into all systems of automobile.
Divide according on the impact of running car performance effect, automobile electronics can be summarized as two classes: a class is electronic control device for vehicle, electronic control device for vehicle will carry out with the use of, the i.e. auto electroincs of so-called " electric-mechanic control system " with mechanical system on car; They comprise driving engine, chassis, electrical control unit.Such as Jetronic, braking anti-lock control, anti-sliding control, polling power controlling, Electronic control suspension, electronic automatic transmission, electrical power steering etc., another kind of is vehicular automotive electronic device, vehicular automotive electronic device is the electronics package that can independently use under automotive environment, and it there is no direct relation with the performance of automobile itself.They comprise vehicle information system (car running computer), navigationsystem, auto audio equipment and tv entertainment system, Vehicular communication system, equipment for surfing the net etc.
The electronic control package of present automobile has had very complete consideration to various situation, but, still there are some places not consider: when the outer temperature difference of Che Neiche in winter is larger, windshield easily produces fog, affects sight line.
The windshield of Current vehicle generally is three layers, from outer toward interior be outer glassy layer, doubling layer and interior glassy layer respectively, and the reason that glass hazes has:
1., when air humidity is certain, when window temperature is lower than dew temperature, will form condensation at windshield surface, this front windshield that namely we often see hazes phenomenon; 2. " interior heat is outer cold " temperature difference is large, it may be tens degree, winter even can reach 20 degree, such glass just there will be fog, namely after the hydrone in car in air touches glass, the cold little water droplet that congeals into of glass temperature chance sub-compared with low moisture, on glass, thickly dotted little water droplet causes the change such as light refraction, reflection, affects sight line.
Generally all by being coated with one deck antidim compound outward at car now, not only inconvenient, and be easy to just lose efficacy, need repeatedly to spray.
Patent " except rain is except fog Windshield system " (application number: the 201310063607.X applying date: 2013-02-28) discloses a kind of except rain is except fog Windshield system, comprise transparent circulation film, upper rotating shaft, lower rotary shaft, except head, described upper rotating shaft, lower rotary shaft are positioned at described transparent circulation film inner ring and make described transparent circulation film keep tension force, and the described head that removes is positioned at described transparent circulation film outer ring and is close to described transparent circulation film.Under rotating shaft on described, lower rotary shaft rotary action, described transparent circulation film continues to rotate, described except head is by the fog on described transparent circulation film lateral surface or rainwater erasing.Provided by the present invention except rain is except fog Windshield system, what can realize Windshield removes rain demist airway dysfunction, overcomes prior art moderate rain and brushes rain and heated windshield, subsides antifog film, uses antidim compound except the deficiency of fog.It is in addition, provided by the present invention that except rain, except fog Windshield system also can be applicable to house, steamer etc., other need to keep lookout windows of getting a clear view.
This mode is only that when there is fog, people carries out demist for the system of starting, intelligence not, and structure is very complicated.
