As the automotive industry continues to evolve through rapid technological iteration, vehicle domain controllers are emerging as the digital nerve center of modern vehicles. By consolidating the computing power of previously distributed electronic control units (ECUs), domain controllers redefine the control architecture across core vehicle domains—including powertrain, chassis, body, cockpit, and autonomous driving systems.
This centralized architecture enables cross-domain coordination and performance optimization, fundamentally reducing system complexity while laying the foundation for vehicle lightweighting, cost control, and faster software iteration.
Against this backdrop, the automated domain controller assembly line developed by LEADTECH, a subsidiary of Lead Intelligent Equipment (hereafter referred to as LEAD), delivers high automation and high precision across the entire production process. The line integrates advanced technologies including 3D + AI vision systems, precision fluid dispensing, and integrated testing platforms.
The system enables a fully integrated workflow covering component feeding, precision assembly, in-line inspection, calibration testing, component sorting, and final packaging. Key processes include FCT testing, fully automated fan assembly, AOI visual inspection, Run-In testing, and EOL testing.
Key Process Capabilities
- Precision Dispensing
The dispensing process supports fully automated coating and inspection integration, enabling uninterrupted material supply without downtime. The system is compatible with more than 30 product variants, while maintaining high-precision control.
- Automated Screw Fastening
The screw fastening module also supports 30+ product models, with real-time monitoring of torque curves. Screw trajectories are programmable, and quick replacement of sockets and bits allows both high flexibility and operational convenience. The system also features automated screw feeding without production interruption.
- 3D Inspection
The 3D inspection system is compatible with multiple product types and performs multi-dimensional checks on pin height, positional accuracy, and bending angles. Detection precision reaches ±0.05 mm, while inspection accuracy remains as high as 99.95%.
The automated domain controller assembly line developed by LEADTECH significantly reduces manual intervention, minimizing operational risks while supporting flexible production for multiple domain controller models. Its core strengths lie in delivering high consistency, high reliability, and high efficiency throughout the assembly process. By minimizing human operational errors, the system ensures stable product quality while significantly improving throughput per unit time.
- Key performance indicators include:
- Overall Equipment Effectiveness (OEE): >90%
- Production Capacity (CT): >40 units per hour (JPH)
- Process Capability Index (CPK): >1.67
- Measurement System Repeatability & Reproducibility (GR&R): <10%
Combined with a compact footprint and streamlined operator configuration, these metrics demonstrate the system‘s strong technical capability and market competitiveness, providing robust hardware support for the large-scale, high-quality manufacturing of vehicle domain controllers.
Amid the wave of intelligent transformation sweeping the automotive industry, the intelligent cockpit has evolved from a functional in-vehicle system into a mobile smart living space—integrating lifestyle, emotion, and digital connectivity.
In China’s automotive market, rapid technological iteration and cross-industry integration are reshaping vehicles from simple transportation tools into a “third living space” that combines work, entertainment, and relaxation. This transformation directly responds to the growing expectations of consumers seeking comfort, privacy, and multifunctional experiences in their vehicles.
At the same time, the deep integration of AI technologies is unlocking unprecedented possibilities for cockpit innovation. Leveraging efficient organizational structures and rapid market responsiveness, China’s intelligent cockpit industry has already established a leading position in the global competitive landscape.
LEAD is actively participating in this transformation, committed to driving continuous technology integration and organizational innovation. Through these efforts, the company aims to deliver clear, reliable, and forward-looking solutions that help translate the vision of intelligent cockpits into scalable industrial reality.
