As the automotive sector accelerates its intelligent transformation, assisted driving has evolved from a "cutting-edge" high-tech concept to an accessible experience for all users, gradually transitioning from the "functional era" to the "experiential era." As a core driver behind this wave, HORIZONROBOT-W (09660) recently launched the most significant upgrade in HSD (Horizon SuperDrive™) history. The new version is based on the industry-leading single-stage end-to-end architecture and reinforcement learning capabilities, delivering a smooth, human-like, and trustworthy full-scenario assisted driving experience comparable to a professional chauffeur.

"Traditional two-stage end-to-end and hybrid architectures using single-stage end-to-end plus rule post-processing adopt horizontal and vertical decoupling, leading to challenges such as increased system modules, higher overall response latency, and information transmission losses. Horizon's HSD creates a truly single-stage end-to-end system with strong defensive driving capabilities that drives very much like a professional driver, pushing assisted driving toward a human-like experience inflection point," stated Lu Peng, Vice President of HORIZONROBOT-W and Head of Strategy & Intelligent Driving Product Planning and Marketing.

**Technical Upgrade: Building Leading "Single-Stage End-to-End + Reinforcement Learning" Architecture**

The leading "single-stage end-to-end + reinforcement learning" architecture represents the biggest highlight of this HSD upgrade. Benefiting from truly single-stage end-to-end capabilities, HSD achieves photon input to trajectory output while maintaining ultra-low latency, defensive driving, and smooth horizontal-vertical integration, significantly enhancing the safety, efficiency, and comfort of assisted driving.

Additionally, through the introduction of reinforcement learning mechanisms that maximize model potential through self-exploration, the HSD system achieves an "intelligence emergence" effect comparable to DeepSeek R1.

**Journey 6P Computing Solution: Purpose-Built for Next-Generation Full-Scenario Assisted Driving**

Meanwhile, HSD's upgrade iteration relies on the robust foundation of HORIZONROBOT-W's Journey 6P computing solution with 560TOPS computing power. This "hexagonal warrior" combines six major advantages: high integration, high computing power, high efficiency, high processing capability, high connectivity, and high safety, along with systematic advantages of software-hardware collaboration, enabling HSD to demonstrate ceiling-level assisted driving experience with "human-like performance and user trust."

**Experience Upgrade: Low Latency, Strong Defense, Smoother Horizontal-Vertical Coupling**

To help the industry and users better understand the capabilities of the new HSD version, HORIZONROBOT-W held Pioneer Experience Days in Shanghai from August 21-24, inviting over 100 media representatives for in-depth testing of the upgraded HSD. HSD demonstrated excellent performance in system low latency, human-like defensive driving, and smooth horizontal-vertical coordinated vehicle control, earning unanimous praise as "China's landed version of FSD" and "smooth relaxation beyond imagination."

**Ultra-sensitive system low latency** delivers extremely fast response performance. For example, when encountering temporary construction zones, the system can quickly generate solutions without hesitation, decisively choosing intelligent detours for dead vehicles and other impassable areas. When facing sudden scenarios like ghost probes and extreme cut-ins, the system responds swiftly with extremely low traffic light start-stop delays and precise, ultra-low-latency execution in complex junction navigation.

**Ultra-reassuring defensive driving strategy** with human-like driving performance. In blind spot scenarios such as right-angle intersections, consecutive right-angle intersections, S-shaped narrow roads, and T-junctions, HSD actively reduces speed, consistent with human drivers' observe-then-proceed driving feel. In dynamic interaction scenarios like narrow roads and congested intersections, HSD intelligently adjusts speed for timely avoidance.

**Ultra-smooth horizontal-vertical coordinated vehicle control** breaks through traditional hybrid architecture limitations, delivering smooth start-stop, seamless interaction, smooth cornering, and agile detour travel experiences. At misaligned intersections, it selects correct lanes and passes smoothly. In complex conditions like traffic canyons, it achieves non-stop interaction with stable direction control without jitter. Even in static scenarios like roundabouts and U-turns, or dynamic-static overlay scenarios like competitive detours and construction zone navigation, it maintains fluid continuity.

**Ultra-impressive reinforcement learning** achieves "intelligence emergence" in assisted driving. Through autonomous exploration and reasoning reinforcement learning, the HSD system can better autonomously handle extreme scenarios. When variable tidal lanes suddenly change from straight-through to U-turn lanes, the system instantly understands the change and enters the correct lane. On completely unmapped construction gravel roads with no obvious road boundaries, the system can autonomously identify roads and obstacles, reasoning out passable areas for smooth progress.

**Safety and Trust: Adhering to Human-Centered Philosophy, Building Strong Safety Foundation**

To create assisted driving products that everyone loves to use, HORIZONROBOT-W not only pursues excellence in technology and experience but also adheres to human-centered product philosophy, building a solid safety foundation.

HORIZONROBOT-W possesses the industry's largest-scale active safety test scenario library, covering over 30,000 scenario datasets and undergoing over 10 million kilometers of extensive mileage regression testing. Notably, HORIZONROBOT-W has earned the world's first and only ISO 8800 Road Vehicle AI Functional Safety Certification, becoming a "safety trust passport" to global markets.

Data shows that HORIZONROBOT-W has achieved safe travel verification for over 5 million families and over 10 billion kilometers, supported by field testing data across more than 50 overseas countries with cumulative mileage exceeding 1.5 million kilometers.

Currently, HORIZONROBOT-W's HSD has entered the mass production countdown phase, scheduled to debut on the Chery Exeed Sterra E05 for mass production delivery within this year. Additionally, HORIZONROBOT-W has reached cooperation intentions with nearly 10 global automotive brands, bringing safe, professional, and comfortable HSD full-scenario assisted driving experiences to more users in the future.

As the intelligent driving industry transitions from "functional competition" to "experience upgrade," HORIZONROBOT-W drives user experience-centered mobility transformation, advancing assisted driving products from "usable" to "user-friendly and beloved," making them accessible to ordinary consumers.
