Auxiliary diagnosis system for automobile fault symptoms and using method thereof

Abstract

The invention provides an auxiliary diagnosis system for an automobile fault symptom and a use method thereof. The auxiliary diagnosis system comprises a case library, an input module, a retrieval module, a case adjustment module and an output module, wherein the case library is used for collecting and storing historical fault cases of automobile faults and corresponding solutions; the input module imports sign information of a current automobile fault input by a user and sends the sign information of the current automobile fault to the retrieval module; the retrieval module establishes a symptom-based fault space according to the type of the historical fault case, matches the symptom information of the current automobile fault sent by the input module with the historical fault case, and sends a matching result to the output module or the output module and the case adjustment module; the output module outputs a matching result of the retrieval module; and the case adjustment module receives the matching result sent by the retrieval module, newly adds current automobile fault symptom information in the fault space, generates a new fault case after fault verification and stores the new fault case.

Description

technical field [0001] The invention relates to the technical field of automobile fault diagnosis, in particular to an auxiliary diagnosis system for automobile fault symptoms and a using method thereof. Background technique [0002] A car is a complex mechanical system composed of multiple systems, and each system is composed of several components, thus forming a multi-level structure. Car failure is the phenomenon that the car cannot complete its function, such as difficulty in starting the engine, failure to start the car, oil leakage, water leakage, lighting system failure, etc. Faults in the car show up. Common faults are: sudden change in working conditions, abnormal sound, abnormal smell, abnormal smoke exhaust, abnormal temperature, abnormal appearance, abnormal consumption of fuel and lubricating oil, leakage, etc. Complicated automobile faults can often be decomposed into multiple small and simple fault causes and symptoms according to levels. Although the variou...
