An Automatic Diagnosis System for Automobile Energy Saving, Emission Reduction and Maintenance

Abstract

The invention provides an automatic diagnosing system for energy conservation, emission reduction and repair of an automobile. The system comprises an energy conservation and emission reduction detecting device, and an energy conservation and emission reduction diagnosing service center, wherein the energy conservation and emission reduction detecting device comprises an oil consumption detecting module, a tail gas emission detecting module, an OBD detecting module, an engine detecting module and a basis system detecting module, and is used for detecting energy conservation and emission reduction data comprising the oil consumption and the tail gas emission of the automobile so as to generate the detected data to be transferred to the energy conservation and emission reduction diagnosing service center to be processed; and the energy conservation and emission reduction diagnosing service center comprises a data analysis server, an intelligent diagnosis server, an on-line expert diagnosing module and an assisting server. The system can be applied to the comprehensive detection for the superscalar positions of the automobile and the intelligent network bug diagnosis, so that maintenance technicians can accurately repair and maintain in time, the unnecessary dismounting for the automobile is reduced, the energy-saving technology of the automobile is promoted, the consumption of the fuel and the discharge amount of the pollutants for the automobile are reduced, and the purposes of energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to an automobile diagnosis system, in particular to an intelligent automatic diagnosis system for energy saving, emission reduction and maintenance of automobiles. Background technique [0002] As of 2011, China's car ownership has exceeded 100 million, becoming the world's second largest car ownership country, and it is still growing at a high speed. China has entered the automobile society; correspondingly, my country's oil imports It has grown substantially every year. In 2007, my country became a net importer of oil, and its dependence on foreign oil exceeded 50%. At present, about 1 / 3 of my country's oil is consumed by cars. With the increase in car ownership, the oil used for cars Demand will further increase, making the environment overwhelmed. In the urban atmosphere, 61% of CO, 87% of HC, and 55% of NOx come from vehicle exhaust emissions, which are important factors that cause global climate anomalies, frequent natural di...

Problems solved by technology

With the extensive application of new energy and advanced energy-saving and emission-reduction control technologies in modern vehicles, most new vehicles have the advantages of energy saving and environmental protection, but the control of fuel consumption and emission of in-use vehicles is not enough

Implementing standard inspection and maintenance (hereinafter referred to as I / M) operations on in-use vehicles to ensure that the in-use vehicles are always in good technical condition is the fastest and most effective way to control fuel consumption and emissions; There are many types of I / M equipment, their performance is uneven, and their functions are relatively single. It is impossible to make a comprehensive and accurate judgment on the cause of exceeding the standard according to a unified standard. When repairing the failure of the vehicle exceeding the standard, it is often neglected, and it is impossible to fundamentally solve the problem of the vehicle exceeding the standard. Therefore, the society is in urgent need of a comprehensive and standardized vehicle fuel consumption and emission testing and diagnostic equipment, which can implement comprehensive testing of vehicles, intelligently find out the fault point and analyze the cause of the fault, and completely eliminate the fault
