Description
Technical field
The utility model relates to provides a kind of automotive diagnostic installation, particularly relates to the embedded device of a kind of special-purpose vehicle and OBDII automotive diagnosis unification.
Background technology
Develop rapidly along with Eltec, digital circuit and large-scale integration circuit have obtained widespread use on automobile, make the automobile computer control system that very big development all arranged aspect control content and the mode, and, the control system of modern automobile mostly is central control system, and its major control content can be summarized as following four major parts:
One is an engine control, and computer system mainly is injection of fuel (EFT), Ignition Control (TSC), emission control (EAC) and air inlet control to the content of engine control.Each sensor is transformed into electric signal with physical quantitys such as the suction quantity of driving engine, intake temperature, engine speed, cooling water temperature, accelerator open degrees and is input to master controller ECU; output signal control actr after rapid analysis, comparison and calculating; make driving engine under various operating modes, all have best fuel delivery and point of ignition, good dynamic property, economy and the low exhaust emission of protection driving engine.
It is two for chassis control, and along with the raising of automobile driving speed, the increase of road travel density proposes higher requirement to the ride safety of automobile performance.Electron steering anti-skid brake system ABS and the driving antislip ASR of system have obtained using widely on automobile, it can improve directional balance and the handling maneuver ability of automobile in braking procedure, shorten stopping distance, and trackslipping of can preventing to drive in the driving process.In order to alleviate the labour intensity of chaufeur, traditional hand-operated transmission is replaced by automatic transmission with hydraulic torque converter (A/T or ECT), widespread use simultaneously power steering, electric control four-wheel steering and electronically-controlled suspension apparatus (TEMS).
It three is safety assurance control, and the safety assurance control of modern automobile mainly is divided into passivity safety assurance and initiative safety assurance.The good automobile of passivity safety assurance performance, in case vehicle generation traffic accident can alleviate occupant's degree of damage to greatest extent, but it does not possess foresight automatic deceleration or parking, the ability that avoids traffic accident and take place.This class device mainly contains electronic security(ELSEC) band, safety air bag (SRS) etc.Initiative safety assurance device can be controlled automatic deceleration or parking by computer by the signal that various sensor and infrared ambulator obtained, thus the generation that avoids traffic accident.This class device mainly contains electronics anticollision device and automatically controlled auto brake system.
It four is travelling comfort and amusement Communication Control, and the design of modern automobile can both embody the design philosophy that people-oriented, particularly aspect car.The automobile full-automatic air conditioner, automatic door and window, central door lock, the automatic electric seat, advanced audio, car phone, electronic charts etc. all be unable to do without Eltec, use computer control that they are well combined, and use convenient.
Vehicle with above-mentioned control system, the quality of each electric-control system service condition directly has influence on the cruising of vehicle.For normal operation and the convenient maintenance that guarantees each system of vehicle, master controller ECU has the function of OBD (On-Board Diagnostics), in automotive use, it can constantly be monitored each sensor, actr and connection line, if work abnormality, master controller ECU then is stored in the memory device the content of the fault form with code, and the indicator lamp of control warning is simultaneously lighted, and gives chaufeur with prompting.When car inspection and maintenance, can read the failure code in the memory device by specific program, service personnel just can be according to the classification and the scope of reading code failure judgement.The read method of diagnostic code and display format, because of vehicle different.
But, owing to the implication of automobile self-diagnosable system failure code, read and the difference of removing method, bring many new inconvenience for the maintenance of automobile, the beginning of the nineties, SAE (SAE) has proposed a new generation with car diagnostic system OBDII (On-Board Diagnositics), and promptly the second generation is with the car diagnostic system.This standard is passed through through EPA (EPA) and California, USA resource association (CARA) authentication, the later stage nineties, automobile that continental United States produces and import are to the automobile of the U.S., the standard that must meet OBDII with the car diagnostic system, because the MES (Market Economy Status) of the U.S., this standard has authority relatively, and up to the present, each big car company has adopted the OBDII diagnostic system basically comprehensively in the world.The OBDII diagnostic system can be monitored in real time to the operation conditions of parts relevant with discharging on the vehicle, guarantee that the vehicle steadily in the real-world operation reaches the design-calculated emission effect, strengthen automotive servicing, maintenance simultaneously, make it keep the good technical state, this also is the fundamental principle of control with the car disposal of pollutants.
At present, China has begun progressively to implement motor vehicle exhaust emission Europe II standard (being called for short Europe II), and the enforcement of Europe III, Europe IV standard is also put on agenda.From 2000, added the requirement that automobile must assemble the OBD system in Europe III and the Europe IV effluent standard, to guarantee to survey effectively the emission of automobile wastes situation.
Therefore, be necessary to provide the embedded device of a kind of later-model special-purpose vehicle and the unification of OBDII automotive diagnosis.
