According to the vehicle alarm method, design is simple, use is convenient, the situation that passengers, especially children, are locked in the vehicle to cause life risks can be effectively avoided, and high practical value is achieved.
Description
Technical field
The present invention relates to field of automobile safety, particularly relate to a kind of based on carbon dioxide induction and the car alarming method of temperature sense.
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.
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 market in vehicle electronics future more trends towards safety, from the demand in market can find out people for the driving technique of safety and the attention rate of product very high.Achieve great progress in passive security technology---namely when automobile collides for driver and passenger provide technology and the product of protection; as the products such as crash sensor, air bag, safety strap, follow-up steering structure and metal sheet collision district and technology have saved the life of many people in automobile collision accident, and decrease personnel's injury.But the latest development direction is active safety, by adopting the technology such as radar, optics and ultrasonic transduter, the Distance geometry of measured automobiles and surrounding objects is close to speed during object.These data can be used for reminding driver to control the drive speed of automobile, avoid contingent collision accident.This information also can be used for control brake or steering swivel system, with automatic collision free.This collision avoidance system can reduce the expensive cost of global accident rate and car accedent.
Universal along with vehicle, child is occurred repeatedly by the event that the careless head of a family is locked in car, some false alarms, some negative and positive two every.Research is had to disclose a merciless world: it is the same that such tragedy occurs in each head of a family probability with it.
Under summer high temperature weather, enclosed vehicle is after being exposed to the sun for a long time, can vehicle interior temperature reach how many? does its " lethality " have again much? external once had the experiment of such street corner.
The several passerby of random choose allows them be sitting in closed automobile and treats 10 minutes, completes and just can obtain 100 dollars.Several passerbys take part in activity, and have recorded into video.All show very easily self-confident when they step in car, but only treated a few minutes, some just start to occur uncomfortable reaction.Be exposed to the sun and allow temperature in car rise violently, they start to occur symptoms such as perspiring, uncomfortable in chest, dizzy.Finally, nobody successfully adheres to getting off, and selects without exception to abandon.
A research finds, when temperature reaches 35 degrees Celsius, solar radiation 15 minutes, the temperature in closure compartment just can rise to 65 degrees Celsius.And ambient temperature is once more than 40 degrees Celsius, human body will heatstroke, shows as that dizziness, dim eyesight, pulse are thin and delicate, degradation symptom under increased heart rate, blood pressure, and severe patient can capture life.
To win a prize the data that article provides according to American journalist GeneWein-garten mono-section of Pulitzer, child is forgotten thing entire United States such in car and can occur 15-25 time for 1 year, run through spring and summer and early autumn.Also have a statistics show, in the past few years, the whole world has 320 children at least because by father and mother have a mind to or stay Che Nei separately unintentionally and cause death, cause the main cause of tragedy be exactly in car high temperature and atmosphere draught-free cause children to suffocate.
Existing vehicle carries out the apparatus and method warned when there is not life danger for the passenger be locked in car.
