摘要
结合低速ABS控制器和硬件在环平台进行ABS硬件在环实验研究.首先在Matlab/Simulink/Stateflow软件中设计了低速ABS的控制算法,包括信号调理、控制逻辑和指令输出3个模块.其次,基于NI-PXI搭建了某越野汽车的硬件在环实验台架,包括上、下位机的构建,真实的方向盘/踏板驾驶员输入,CarSim RT的车-路模型调用以及实时信号交互.通过汽车倒坡制动的硬件在环实验表明,所设计的硬件在环实验平台能有效地模拟出实际制动时ABS的控制过程,同时ABS算法也能保证大坡道制动时越野汽车具有良好的方向稳定性.
Abstract
Combining the low-speed ABS controller with hardware-in-the-loop(HIL)platform,an experimental study on ABS hardware-in-the-loop was conducted.Firstly,the control algorithm for low-speed ABS was designed in Matlab/Simulink/Stateflow software,comprising three modules:signal conditioning,control logic,and command output.Subse-quently,a hardware-in-the-loop testbed for a specific off-road vehicle was established based on NI-PXI,involving the con-struction of both upper and lower computers,real steering wheel/pedal driver inputs,invocation of the CarSim RT vehicle-road model,and real-time signal interaction.The hardware-in-the-loop experiments for downhill braking demonstrated that the designed hardware-in-the-loop experimental platform effectively simulates the actual ABS control process during bra-king.Simultaneously,the ABS algorithm ensures good directional stability of the off-road vehicle during downhill braking on steep slopes.
