多轴分布式电驱动车辆电液复合制动控制研究
Electro-Hydraulic Composite Brake Control for Multi-Axis Distributed Electric Drive Vehicles
摘要
Abstract
In response to the issue of vehicle brake jitters commonly seen in electric-hydraulic composite braking systems driven by multi-axis distributed motors,two strategies are proposed:a motor braking power correction strategy during the pressure buildup stage and a coordinated control strategy based on feedforward-feedback.These strategies respectively address brake jitter by coordinating the composite braking force during the pressure build-up phase and other stages.A PID control-based strategy for ABS has been developed to resolve the braking conflict arising from the simultaneous operation of the ABS and the motor braking system by adjusting the motor braking force.The effectiveness of the proposed approach was validated by conducting a comprehensive joint simulation using TruckSim,Matlab/Simulink,and AMESim.Results show that the brake jolt decreases by 20.66%during the pressure buildup phase and 92.59%during the motor exit phase,significantly improving the overall driving experience.Furthermore,the ABS control strategy facilitates the recuperation of braking energy while maintaining the ideal slip ratio.Supported by the full vehicle braking test results,the coordinated control strategy achieves efficient recuperation of braking energy while ensuring good braking performance.关键词
