Description
Technical field
The present invention is a kind of vehicle exhausting control and remote failure diagnosis system of relating to, and can be widely used in motor vehicle emission management and the vehicle failure maintenance management.
Background technique
At present, Beijing has come into effect state III automobile emissions standards.This standard is the emission standard of country's phase III, and it is equivalent to European III emission standard, and CO, NOX, HC, CO2 are taked stricter restriction.Will solve by skill upgrading and will reach this target, in automobilism whole process, constantly monitor the discharge quality of tail gas, in case finding automobile breaks down with the related elements of controlling exhaust emissions in running, will report to the police at once, thereby remind the driver immediately car to be overhauled, be in the environmental protection state constantly to guarantee automobile.For this reason, state III automobile emissions standards mandatory provision: new car must be installed OBD vehicle-mounted self-diagnosis system (being the abbreviation of On-Board Diagnostics).These system's characteristics are that Check point increases, detection system increases, and lambda sensor is all arranged on the inlet/outlet of three-way catalytic converter.
In fact, from the 1980's, each automobile factory of the world just is equipped with Full Featured control and diagnostic system on vehicle.These new systems can warn driving when vehicle breaks down, and can be via specific mode read failure code when maintenance, and to accelerate engineering time, this is an onboard diagnostic system.By 1985, California, USA atmosphere resource bureau (CARB) begins to formulate rules, the vehicle that requires each Railway Car Plant to sell in the California must install the OBD system, and the OBD system that is equipped with on these vehicles is called as OBD-I (first generation is with the car diagnostic system).
Originally the purpose of Air-Resistance Board of the State of California's formulation OBD-I is will reduce automotive exhaust gas and simplify maintenance flow, but because OBD-I is rigorous inadequately, omit the efficiency monitoring of ternary catalyzing unit, the leakage detecting of oil gas evaporation system and the detection whether motor lacks fire, caused hydrocarbon emission to increase.The Monitoring Line susceptibility of adding OBD-I is not high, realizes by the time when vehicle trouble advances factory's maintenance again, has in fact discharged a large amount of waste gas.
OBD-I is except controlling toxic emission effectively, and it also causes the problem that another is serious: each Railway Car Plant has developed diagnostic system, maintenance flow process, the special tool etc. of oneself, brings many problems for non-special service station technician's maintenance work.Air-Resistance Board of the State of California (CARB) soon OBD-I system is more and more far away from the target of formulating originally, promptly begins to develop the second generation with car diagnostic system (OBD-II).
OBD-II can monitor vehicle exhaust continuously in the operation conditions of motor, in case find that tail gas exceeds standard, will give the alarm at once.When system broke down, fault (MIL) lamp or inspection motor (Check Engine) emergency warning lamp were bright, and engine computer deposits fault message in storage simultaneously, failure code can be read from engine computer by program.According to the prompting of diagnostic trouble code, the maintenance man just can determine the character and the position of fault quickly and accurately.
OBD-II systems technology advanced person, very effective to surveying emission status.When finding that trouble lamp is lighted, should immediately car be delivered to the maintenance station and overhaul.But whether the driver is accepted the warning of MIL, and OBD-II is helpless, and vehicle exhausting control of the present invention and remote failure diagnosis system have solved this problem.
The main purpose of vehicle exhausting control of the present invention and remote failure diagnosis system is that the detection, the maintenance and management that make automobile are integrated, to satisfy requirement on environmental protection.Vehicle exhausting control of the present invention and remote failure diagnosis system can enter respectively among the system ECU such as motor, speed changer, ABS by the OBD interface and go read failure sign indicating number and other related data, and utilize the GPRS communication system, information automatic announcement managerial departments such as identity code, diagnostic trouble code and position with vehicle, managerial department sends instruction according to the grade of this vehicular discharge problem to it, comprise the suggestion of where keeping in repair, solve the time limit of emission problem etc., also can send forbidden instruction the violator's that exceeds the time limit vehicle.Therefore, vehicle exhausting control of the present invention and remote failure diagnosis system can give a warning to the driver to the vehicular discharge problem, can also punish the violator, and can remote failure management and information service.
Patent vehicle breakdown diagnostic system (CN1745008) is the system of a kind of faut detection, Fault Identification and fault recovery, compare with remote failure diagnosis system with vehicle exhausting control of the present invention, patent vehicle breakdown diagnostic system (CN1745008) does not have exhausting control and management function, in fault diagnosis, only be used for faut detection, Fault Identification and fault recovery, do not have the support of large vehicle Mishap Database, and the information service etc. of maintenance garage is not provided.Patent vehicle breakdown diagnostic system (CN1745008) does not provide the vehicle position informations such as information of GPS in information transmitted.
Patent is a kind ofly to realize remote data transmission and diagnosis by the internet based on Internet OBD-II standard automobile fault remote detecting system (CN1406794), thereby provides services such as comprising Automobile Detection, maintenance consulting, auto parts machinery and car load sale, automotive engineering consulting, automobile consumption amusement for the user.This invention is based on the service system of internet, so move inconveniently, and vehicle-carrying communication can not provide service by computer and centre information system contact always, and uses car-mounted computer also inconvenient.
Vehicle exhausting control of the present invention and remote failure diagnosis system can provide long distance wireless fault diagnosis, GPS information service, exhausting control and GPRS communication function etc., and the detection of automobile, maintenance and management are integrated.
Summary of the invention
