Description

Based on the on-board air conditioner householder method of temperature sense
Technical field
The present invention relates to vehicle electric field, particularly relate to a kind of on-board air conditioner householder method based on 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 important effect of vehicle electronics improves the safety of automobile, traveling comfort, economy and recreational.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.
Automotive circuit diagram is considered to the revolution in automotive technology development process.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.
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.
2008 Eltec development direction develop to concentrated Comprehensive Control: by engine management system and automatic transmission control system, be integrated into the Comprehensive Control (PCM) of power drive system; Braking anti-lock control system (ABS), anti-slip regulation (TCS) and anti-slip regulation (ASR) are combined and carries out control for brake; By central chassis controller, by braking, suspension, turn to, power transmission dispatch control system connected by bus.Controller, by complicated control algorithm, is coordinated each subsystem, road holding is controlled to optimum level, form integrated chassis control system (UCC).
Due to sharply increasing of the electronic apparatus device quantity on automobile, in order to reduce the quantity and weight connecting wire, network, bussing technique have a great development during this period.Bussing technique is that various auto electroincs is connected to become a network, is sent and received information by data bus.Electronics package, except the respective controlling functions of complete independently, can also provide data, services for other control setup.Owing to employing the design of networking, simplify wiring, decrease the quantity of electrical node and the consumption of wire, fitting work is more simplified, too increase the reliability that information transmits simultaneously.Can access any one electronic control package by data bus, read failure code carries out trouble diagnosing to it, makes car load maintenance work become more simple.
The application of automotive electronic technology will make automobile that following Main change occurs:
One, also will there is great change in the physical construction of automobile, and the various maneuvering systems of automobile, to electronization and motorized development, realize " line manipulation ".Original mechanical transmission mechanism is replaced, such as " wire braking ", " wire turns to ", " E-gas " etc. with wire.
Two, automobile 12 volts of electric power systems are to 42 volts of conversions.Along with auto electroincs gets more and more, the electric energy of consumption increases significantly.Existing 12 volts of electrical source of power, can not meet the needs of all electric systems on automobile.To adopt integrated actuating machine-electrical generator 42 volts of electric power systems from now on, electrical generator maximum output power will bring up to about 8 kilowatts by 1 kilowatt in 2005, and generating efficiency will reach more than 80%.The enforcement of 42 volts of automotive electrical system new standards, will make the design of car electrics parts and structure that great change occurs, and mechanical relay, fuse wire type protective circuit will be eliminated.
The application of automotive electronic technology will make automobile more intelligent.Intelligent vehicle is equipped with multiple sensors, can the situation of fully perception motorist and passenger, and the information of traffic facilities and ambient environment, judges whether occupant is in optimum regime, and whether vehicle and people can cause danger, and take countermeasure in time.
The a/c system of existing automobile does not generally have ancillary system, a/c system refrigeration or the gas after heating is blown in car to carry out interchange of heat, it freezes or heats very slow under the situation that car internal and external temperature difference is larger, because car inner air and outer air itself exchanges slowly, mainly carries out interchange of heat.
This experience is fairly obvious in summer; automobile is after quick-fried Sai; temperature in car may up to more than 60 degree; and the temperature about 30 degree outside car; now automotive air-conditioning system refrigeration limits by external factor, and refrigeration performance is limited, and the air inerchange of a/c system itself is slow; vehicle interior temperature is reduced and slowly, often needs door opening or vehicle window heat radiation for a long time.
