Automotive industry is a huge system engineering. High-quality products depend not only on the oretical analysis，but also on long-term accumulated production experience and expertise.

The foreign auto industry has a history of hundreds of years，and has built a large number of product platforms. Numerous product platforms have accumulated a large amount of data by the form of databases，models and product platforms during the process of design and experiment. In contrast，the domestic automotive engineering industry still has a long way to go. With the development of the Internet，to establish the automotive engineering database and related data system under the Internet model is the fastest，most efficient and lowest cost way in the process of automobile development especially in the absence of systematic and comprehensive data accumulation in the domestic industry. The method therefore has great potential for development in the domestic automotive industry.In this paper，the development history and technical level of automobile engineering data on domestic and abroad are compared.The development of domestic automobile engineering data is expounded systematically and the data system of “automotive engineering big data” is put forward.The application of domestic automobile industry is explained combined with Internet big data，which will provide technical support for the coordinated development of automotives and communications，electronics，human body，information，transportation and other fields.
