摘　　要：为解决传统车辆液压制动系统响应滞后、ABS存在滑移率非线性等问题,设计了一种“行星齿轮减速机构+滚珠丝杠+活塞”的电子机械制动执行器方案,提出一种基于滑移率的ABS自抗扰控制策略,使电子机械制动系统能够快速、准确地调节各个车轮的制动力,有效满足ABS的要求。运用Matlab/Simulink验证执行器的响应性能,分别在2种路面工况下进行ABS制动过程的仿真。研究结果表明:自抗扰控制对于系统内外部扰动具有较强的鲁棒性,能保证车辆的前、后轮滑移率更快稳定在目标滑移率处,有效减少了车辆的制动时间与制动距离。Under the development trend of electrification and intelligence,the automobile braking system has ushered in revolutionary changes.Traditional hydraulic braking system typically has a slow response time.This delay is critical in emergency situations where immediate braking is required.The complexity of hydraulic system,which include numerous components such as master cylinders,brake lines,and calipers,makes them more challenging to maintain.It is necessary to perform regular maintenance in order to ensure that the system functions correctly.This can be a time-consuming and costly process.One of the most prevalent issues associated with hydraulic braking systems is fluid leaks.It is possible for brake fluid to leak from a number of different points within the system,including the master cylinder,brake lines,or calipers.Leaks may lead to a reduction in braking power,which increases the risk of accidents.Compared with the traditional vehicle hydraulic braking system,the Electro-Mechanical Braking(EMB)system completely eliminates the hydraulic device and is powered by an electric motor to generate the braking clamping force.The system has a simpler configuration,a faster response time,a smaller quality and volume,and represents an important development direction for future automotive brake-by-wire technology.Meanwhile,as the number of vehicles in China increases,the demand for safety performance continues to rise,leading to more passenger cars being equipped with electronic braking control systems,such as Anti-lock Braking System(ABS),to prevent wheel lock-up during braking and improve vehicle stability.The EMB system is fully electronic and easily integrated with the vehicle’s electronic control system.This integration capability allows the ABS system to work better with other safety systems to provide more comprehensive control of vehicle dynamics.However,the EMB system also faces challenges such as strong nonlinearity,large load variations,and complex control.During emergency braking,the ABS is often disturbed b
