To address the unique characteristics of commercial vehicles—such as their large size, numerous blind spots, and complex operational conditions—this solution offers a professional millimeter-wave radar system. By deploying multiple high-resolution millimeter-wave radars in forward, lateral, and rearward positions, the system establishes a comprehensive, all-around perception network capable of delivering four-dimensional, high-precision target information that includes distance, velocity, azimuth angle, and pitch angle simultaneously. The system’s output data effectively distinguishes between various target categories, such as vehicles and pedestrians, significantly enhancing the reliability of perception for large-scale vehicles operating in intricate environments. This robust perception capability is essential for enabling L3-level and higher autonomous driving capabilities in commercial vehicles, with all core sensors having successfully passed international safety certifications.
