Abstract
The present invention relates to a system for analyzing and controlling the degree of the influence of frost and fog on driving vision. The system includes a frost and fog sensor, a central controller, an automatic braking device, an air conditioner controller and a vehicle window heating device; the signal output end of the frost and fog sensor is connected with the signal input end of the central controller; and the signal output ends of the central controller are connected with the automatic braking device, the air conditioner controller and the vehicle window heating device. The invention also discloses a control method of the system. The control method includes the following steps of: S1, signal acquisition; signal processing; and S3, execution processing. According to the system and the control method of the invention, in the driving process of a vehicle, sensors acquire the values of temperature and humidity inside and outside the vehicle and the temperature of the body of glass in real time and send the signal to the central controller; the central controller judges the degree of the influence of the frost and fog on the driving vision in real time and outputs a judgment result to the air conditioner controller and the vehicle window heating device; and defrosting and defogging can be carried out automatically. The whole system is safe and reliable, can ensure driving safety in frost and fog weather, and is high in automation degree.
Description
Technical field
The present invention relates to vehicle driving safety and control technical field, particularly frost mist to the analysis of driving vision influence degree and control system.
Background technology
Raising day by day along with people's living standard; automobile come into more and more the common people other; the owning amount of passenger car sharply increases; vehicle driving safety problem becomes a major issue of harmonious society, and a main research and development problem of world today's development of automobile is exactly to protect pedestrian and the safety of passengers inside the car to greatest extent.
Winter, spring, rainy season are because of ambient temperature, humidity change, when vehicle travels, vehicle window easily hazes frosting, at present when frosting occurs in vehicle window and hazes and affects driving vision, it is both needed to artificially judge, and need manual to carry out air-conditioning unlatching and defrosting mode selects and vehicle window heater switch such as opens at the sequence of operations, in the case of the visual field is in poor shape, carries out manual operation disperses very much driver attention, have influence on traffic safety.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of safe and reliable and frost mist that automaticity is high is to driving vision influence degree analysis and Control system and control method.
The purpose of the present invention is achieved through the following technical solutions: frost mist is to driving vision influence degree analysis and Control system, including frost mist sensor, central controller, self-braking device, air-conditioner controller and vehicle window heater, the signal output part of frost mist sensor is connected with the signal input part of central controller, and the signal output part of central controller is connected with self-braking device, air-conditioner controller and vehicle window heater respectively.
Described frost mist sensor includes temperature sensor and humidity sensor.
Described temperature sensor is installed in car, car is outer and on glass, described humidity sensor is installed on outside Che Nei and car.
Based on the described frost mist control method to driving vision influence degree analysis and Control system, comprise the following steps:
S1, signals collecting: frost mist sensor acquisition car internal and external temperature and moisture signal, gather the temperature signal of glass simultaneously, and all signals passed to central controller；
S2, signal processing: the temperature and humidity signal received is processed by central controller, and carry out fuzzy operation according to the formation basic theory of frost mist, frost mist situation is affected visual field degree and carries out real-time judge, and will determine that result is divided into without impact, minimal effect, considerable influence and has a strong impact on several grade；
S3, perform process: when judged result is minimal effect and considerable influence, central controller controls air-conditioner controller and the work of vehicle window heater, carrying out automatic defrosting and remove mist, air-conditioner controller affects visual field degree to central controller feedback frost mist situation in real time simultaneously；When judged result is for having a strong impact on, central controller controls self-braking device works, vehicle deceleration, and when judged result is without affecting, freeing vehicle slows down.
The invention have the advantages that
nullFrost mist sensor is placed at vehicle window correct position，Sensor Real-time Collection car room in vehicle traveling、The value of temperature and humidity and glass body temperature in outer air，And send signal to central controller，The principle that central processing unit is formed according to frost mist carries out fuzzy operation，Frost mist situation is affected visual field degree and carries out real-time judge，Controller will determine that result exports to air-conditioner controller and vehicle window heater，Automatically defrosting-defogging is carried out，Air-conditioner controller opens air-conditioning according to central controller input information、Regulation air conditioning mode、Air supply velocity and vehicle window heater is carried out computer heating control，Air-conditioner controller will perform feedback of status to automatic defrosting demister system central controller，Carry out new round calculating，When occurring that " having a strong impact on " and air-conditioner defrosting are to no effect, this signal is sent to self-braking device and slows down by processor，Whole system is safe and reliable，Can ensure that the traffic safety of frost mist weather，And automaticity is high，It is not required to artificial Non-follow control，Make driver can concentrate one's energy to drive.
