The automotive supply chain contains various suppliers, manufacturers, logistics providers, sellers and other subjects, forming a complex and huge system, of which parts supply is a key link in the industry chain, and the suspension of individual or partial suppliers upstream may trigger a "broken chain" crisis in the supply chain.

    After years of development, the auto parts supply chain has formed a global distribution and procurement pattern. The current international division of labor in the automotive industry, Europe and the United States in the chip, technology platform, precision machining components and other areas of obvious advantage, while Japan and South Korea in optical instruments, integrated circuits and other areas with a competitive comparative advantage, China has certain advantages in the interior and exterior trim, stamping parts, batteries, motors, electrical equipment and other areas.

    From our combing domestic auto parts industry chain supply chain, most of the current domestic supply of primary components can be basically solved, but the typical supply of secondary and tertiary components have a certain degree of restricted risk. We sorted out the urgent need to achieve independent control of the three main lines.

    Clue one: the first-level assembly parts electric steering system, line control of the dynamic system; clue two: secondary components including engine fuel control system, supercharger, solenoid valve in the transmission, torque converter, steel belt, etc., the brake system in the ESP, IBS, thermal management system in the electric compressor, ADAS in the millimeter wave radar, etc.; clue three: key electronic components such as IGBT, chips, sensing elements.
