摘　　要：为提高现有线控制动系统的集成度,研究开发了一种压力顺序调节制动系统。通过建立的数学模型仿真得到系统的参数需求,并形成了由电机、滚珠丝杠、主缸及传感器等组成的样机。建立了基于Matlab/Simulink与veDYNA联合仿真的硬件在环试验平台,设计了模糊PD控制器,针对样机的ABS功能进行了硬件在环试验。试验结果表明:系统可以实现各轮缸压力的顺序调节,单轮缸调压频率达到20Hz,受限于电机的性能,系统只能实现部分ABS功能。To improve the integration of the brake-by-wire system,a braking system,which can realize pressure individual regulation of the wheel cylinder,was developed.The parameters of the system were obtained by mathematical modeling and simulation.A prototype consisting of motor,ball screw assembly,master cylinder,sensors and other components was developed.The Hardware-in-the-loop（HIL）test rig was set up based on the co-simulation of MATLAB/Simulink and veDYNA.A fuzzy PD controller was designed and HIL test for ABS function of the prototype was carried out.Results show that the hydraulic pressure of the wheel cylinders can be individually regulated,and the single wheel cylinder pressure regulation frequency can reach 20 Hz.Limited by the performance of the motor,the system can only realize part of the ABS function.
