Abstract: In the process of automobile research and development (R&D), there will be defects in all aspects, such as unreasonable design scheme, insufficient structural design strength, and substandard vehicle performance. It is very important to find design defects in the R&D stage and carry out reasonable closed-loop management. Based on the quality management system of Automotive Engineering Institute, Guangzhou Automobile Group Company Limited, the R&D projects of Trumpchi EMPOW and other vehicle models, this paper briefly summarizes the whole life cycle management process of design defects in the R&D process from putting forward to closing. It focuses on the rapid and accurate filling of R&D test quality problems and their statistical methods based on digital technology. At the same time, it also introduces the analysis and digital implementation methods of vehicle R&D test quality problems. The description of common design defects templated by digital technology, the test quality problem record form automatically filled according to the test task information, and the problem grade intelligently recommended by machine learning algorithm, which can greatly improve the filling efficiency and accuracy of test quality problems. Based on the comprehensive application of modern digital technologies such as the internet of vehicle, 5G and digital modeling of analytical methods, the efficiency of quality problem analysis can be greatly improved.
