Automatic Gantry steering System (AGSS)

By leveraging AI‑powered visual perception integrated with GNSS, the system performs trajectory correction and positioning for heavy vehicles. It continuously monitors the vehicle’s travel posture in real time, determines the magnitude and direction of any deviation, and implements speed reduction, stopping, and course‑correcting maneuvers to ensure a straight, stable travel path and precise positioning, guiding the vehicle to its designated berth.

Core capacity:
Non‑slip touch strips, ground magnetic markers, and other positioning aids feature low retrofitting costs.
Under both high-speed and low-speed conditions, the deviation correction standard is within 3 cm.
Small torque adjustments are made every 200 ms to refine the direction, resulting in smoother voltage and current.
AI Vision + GNSS Dual Redundancy

Product Features:
Lower cost
There is no need to install additional infrastructure such as conductor rails or magnetic markers, significantly reducing retrofitting costs and construction complexity.
Better standard
The mainstream industry requires that the deviation correction for large vehicles be within 5 centimeters; HIRI FUTURE’s vision solution, whether at high or low speeds, can keep the deviation correction within 3 centimeters, with even stricter correction and protection standards.
More reliable
Based on extensive scene‑data modeling and autonomous learning, it can maintain stable correction even under conditions such as faded lane markings and ground‑level interference.

Better performance
The system performs fine torque adjustments to the steering direction approximately every 200 milliseconds, resulting in smoother voltage and current variations and thereby achieving deviation correction that surpasses human control.

Dual redundancy
Dual redundancy with AI vision and GNSS solutions: When satellite signals are blocked or unavailable, the AI vision system can independently perform positioning, navigation, and error‑correction protection; and when ground markings are missing or damaged and cannot be recognized by vision, the GNSS solution can likewise operate autonomously to provide positioning, navigation, and error‑correction protection.

Comprehensive functionality
Supports Autonomous driving, crossing streets, and Autonomous driving between Stack yards, enabling Intelligent scheduling across the entire Procedure.

Lighter impact
The control algorithm is integrated into the host computer, minimizing modifications to the existing PLC and on‑board control system, and ensuring compatibility with a wide range of drives and anti‑sway systems.
