AI Technical Summary

Technical Problem

Existing explosion-proof wire-controlled trackless rubber-tired electric vehicles used in underground coal mines suffer from problems such as slow steering response, low accuracy, and long steering time under complex working conditions.

Method used

The system employs a multi-mode steering system, including a control subsystem, a front-wheel steering subsystem, and a rear-wheel steering subsystem. The vehicle's steering is monitored and controlled in real time through the vehicle controller, sensors, and a display screen. Combined with coordinated front and rear wheel steering, it provides steering torque compensation and steering force drive.

Benefits of technology

It improves the vehicle's steering flexibility and maneuverability, enhances the precision and reliability of steering control, ensures a stable and controllable steering process, and improves driving safety and comfort.
