Chinese car door industry

The integration of AI in the Chinese car door industry over the past decade has evolved from single function automation to a fully intelligent system of 'perception interaction manufacturing'. On the user interaction side, AI driven biometric technology enables seamless entry, while facial recognition and palm vein unlocking have been mass-produced in models such as NIO ET7 and Xiaopeng G9. The response delay for gesture control and voice door opening is less than 200ms, and HarmonyOS has supported the 'lift your hand to open' scenario; On the manufacturing end, the 'SmartFit' system of the company uses AI vision and digital twins to achieve high-precision automatic assembly and adjustment of the gap between the car door and the body by ± 0.3mm. The single cycle time is shortened to 7 seconds, and the yield rate is increased by 40%. The Daming AI flying beat technology achieves micrometer level defect detection for door panel interiors, covering 23 types of defects such as scratches, color differences, and solder joints. Minsheng Group has taken the lead in embedding 77GHz millimeter wave radar into door panels, achieving the integration of DOW door opening warning and lateral collision warning, and increasing the value of bicycles by 300%. The penetration rate of APP control and hidden door handles exceeds 66%, and the market size of smart car doors will exceed 60 billion yuan by 2025 and reach billions by 2030. The industry is transforming from 'mechanical components' to 'intelligent interactive entrances', and AI has become the core engine for defining user experience and safety boundaries in car doors.
