Live working vehicle anti-rollover stability control system based on PID algorithm

Abstract

This invention relates to the field of automatic control technology, specifically to a roll prevention and stability control system for live-line work vehicles based on a PID algorithm. It includes a slope recognition unit for acquiring ground slope and terrain changes along the vehicle's forward direction using a multimodal sensor mounted at the front of the vehicle; a stability prediction unit for real-time monitoring of the vehicle's operating parameters and predicting the vehicle's stability on slopes based on the ground slope, thereby generating an adjustment factor; and a control optimization unit for adjusting the vehicle's suspension and power systems based on the adjustment factor transmitted from the stability prediction unit, combined with a PID control algorithm. This system incorporates the influence of friction between the vehicle and the slope, enabling dynamic adjustment of the control strategy, optimizing vehicle stability, preventing roll or instability in complex terrain, and improving the safety and reliability of the work vehicle on slopes.
