specific Embodiment

[0119] Suppose you want to evaluate the reliability of a certain brand "A" model, specifically:

[0120] 1) In the data retrieval unit, by calling the brand model library in the reliability database, the information of the "A" model in the automotive electronic health record system is obtained. In the data retrieval unit, input the index conditions: select the "A" brand in the brand model library for the brand, select the "A" model in the brand model library for the model / car series, select "All" for the mileage, and select "All" for the vehicle attribution , so as to obtain all the maintenance records of the target models that meet the retrieval conditions in the automotive electronic health record system. When calling other model data, the target data can be obtained flexibly by changing the index conditions. The brand model library is as follows:

[0121]

[0122]

[0123] 2) After entering the data retrieval conditions, in the automotive electronic health record sy...

Abstract

The invention discloses a system for evaluating the automobile use reliability and a method thereof. An automobile electronic health record system is utilized, and the use reliability of the vehicle model is evaluated through mining, collection, retrieval, processing and analysis of big data so as to obtain the relatively objective and accurate evaluation conclusion. The applied data include vehicle information which includes the vehicle VIN code and the license plate number; maintenance record information which includes maintenance items, fault description, maintenance parts and maintenance mileage; and maintenance enterprise information. The fault data are classified and then a single vehicle cumulative equivalent fault number change curve along with the mileage and a reliability index calculation result are obtained, and then comparative analysis is performed on the reliability index calculation result and the reference data so as to determine the use reliability level of the target vehicle model.

Description

technical field [0001] The invention relates to vehicle safety evaluation technology, in particular to an evaluation system and method for vehicle reliability. Background technique [0002] In recent years, with the rapid development of my country's national economy, the number of automobiles has continued to increase, which has continuously stimulated the development of the automobile industry, which has also brought challenges to my country's automobile industry.
