[0002] As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the automobile industry, which is being carried out vigorously and in full swing, requires a strong parts system to support it. The independent brand and technological innovation of the whole vehicle need parts as the basis, and the independent innovation of parts has a strong driving force for the development of the whole vehicle industry. They influence and interact with each other. Without the independent brand of the whole vehicle, the research and development and innovation capabilities of the strong parts system are difficult to burst out. Without the support of a strong parts system, it will be difficult to make the independent brand bigger and stronger. The world's major automobile companies have reformed their supply systems and implemented global production and global procurement, that is, from purchasing from multiple auto parts manufacturers to purchasing from a few system suppliers; from purchasing from a single auto part to purchasing from a module; from implementing domestic procurement to global procurement. The reform of the procurement system of vehicle manufacturers requires auto parts manufacturers to constantly adapt to it. It not only requires auto parts manufacturers to expand their own strength, improve product development capabilities, and achieve system development and system supply, but also requires them to shorten the development cycle and provide high-quality and low-cost products. This change has promoted the process of mergers and acquisitions and restructuring in the automotive parts industry around the world. Since auto parts are an important part of the car, they need to be tested during the production process to ensure the quality of the car.
