Last night, the 2025 Horizon Robotics High-Order Intelligent Driving Product Launch Event took place, marking the official debut of the Horizon High-Definition Surround (HSD) urban autonomous driving system. Positioned as a competitor to Tesla's Full Self-Driving (FSD), HSD is designed to be compatible with any automaker. According to Yu Kai, the founder of Horizon Robotics, HSD employs an innovative one-stage end-to-end architecture, facilitating a seamless loop from "photon input" to "decision planning" to "trajectory generation." The system boasts capabilities in environmental comprehension, multi-modal candidate trajectory generation, and personalized decision-making, substantially enhancing the adaptability, stability, and safety of intelligent driving systems.
