1. Development history

Three changes have taken place in the large-scale industrial production mode of automobiles: the production line mode, the platform-type production of automobiles, and the "modular" production mode.

2. Production line mode

At the beginning of the 20th century, Ford created a production process that affected the entire world industry when manufacturing Model T-cars-the production line, which greatly reduced the production cycle and cost, and also reduced the price. As the mainstream way of automobile production, the assembly line continued until the 1980 s. Kan

3. Automotive platform production

With the progress of science and technology and the change of the market, the life cycle of a model is getting shorter and shorter, and the mass production mode gradually becomes unable to adapt to the competition. In the 1980 s, a concept called "car platform" was developed. The "car platform" is a product platform designed by automobile manufacturers and shared by several models. The car platform is related to the basic structure of the vehicle. Different vehicles from the same platform have the same structural elements, such as door pillars, fenders, roof contours, etc. The wheelbase of models on the same platform is generally the same, and some accessories are common. Sometimes many different brands of cars are on the same platform, while different annual models of the same brand are not on the same platform. Kan

4 "Modular" mode of production

Under the "modular" production mode, the focus of automobile technological innovation is on parts and components, which should be developed ahead of time and participate in the product design of automobile manufacturers. For example, Delphi Systems has successively introduced modules such as cockpit, interface disc brake, door, front end, integrated air/fuel, etc. On the other hand, automobile manufacturers take the world as a space to select and match the automobile module, optimize the automobile design scheme, and transfer part of the assembly labor on the automobile assembly line to the place outside the assembly line. The use of "modular" production methods is conducive to improving the variety, quality and automation level of auto parts, improving the assembly quality of automobiles, and shortening the production cycle of automobiles. Several independent brands, including GM's Kaiyue, are actually taking this road.
