AI Technical Summary

Technical Problem

Traditional manual lightweight outdoor loading vehicles require manual pushing/towing, which is physically demanding for extended periods, has insufficient positioning accuracy, unstable target recognition, a single and rigid obstacle avoidance strategy, unstable motion control, poor system module coordination, and cannot achieve stable operation and safety assurance in multiple scenarios.

Method used

The automatic following control method adopts the fusion of UWB and vision. Through the fusion of UWB and vision positioning, combined with PID closed-loop control and ultrasonic obstacle avoidance detection, it achieves accurate positioning and dynamic obstacle recognition. The dual-filter noise reduction process improves positioning stability. Combined with a three-level safety distance graded deceleration and parking mechanism, it supports seamless switching between automatic following and remote control, ensuring stable following and safety of the vehicle in complex outdoor environments.

Benefits of technology

It significantly improves positioning accuracy and target recognition stability, vehicle movement smoothness and safety, achieves stable following and obstacle avoidance in complex outdoor environments, supports automatic following and obstacle avoidance control in multiple scenarios, and enhances the coordination and safety of system modules.
