重型车辆防侧翻智能混合控制研究
Research on anti-rollover control of heavy vehicles based on intelligent hybrid control
摘要
Abstract
Heavy vehicles are prone to instability and rollover under high-speed turning scenarios.To address this,a rollover control strategy that integrates fuzzy adaptive PID control and differential braking control is proposed.A 3-degree-of-freedom rollover dynamics model consisting of lateral,yaw,and roll motions of the vehicle is built.The lateral stability of the vehicle is determined by the value and magnitude of the lateral load transfer rate(LTR),and the optimal additional yaw moment is determined through a fuzzy adaptive PID controller.Finally,the strategy is validated through joint simulation using Trucksim and Matlab/Simulink.Results show after adopting this control strategy,the lateral load transfer rate is controlled within the set range,and the body roll angle is controlled between-2.4° and 2.4°.Moreover,the lateral acceleration is improved by 24.41％.Therefore,the control strategy improves the vehicle stability and anti-rollover control capability under high-speed turning scenarios.关键词
