摘　　要：针对电磁与摩擦集成系统模式切换响应性问题,分析了双盘式电磁与摩擦集成制动系统工作原理和特性。为了克服液压制动力响应慢导致制动模式切换时液压系统无法快速介入,影响制动稳定性问题。提出了基于“前馈+死区”补偿的液压制动响应策略,当需要电子液压制动器工作时,先给电子液压制动器发送一个预启动信号,之后再发送目标需求制动力信号,以消除主缸液压力爬行问题;利用集成制动系统中电机再生制动力来补偿主缸液压力,以解决建压死区问题。在MATLAB/SIMULINK仿真软件下对所提出的控制策略进行了验证,并基于硬件在环系统进行试验研究,结果表明所提出的控制策略能够有效地改善模式切换响应性。Aiming at the problem of responsiveness of mode switching in the electromagnetic and friction integrated system,the working principle and characteristics of the dual disc electromagnetic and friction integrated braking system are analyzed.In order to overcome the problem that the hydraulic system cannot intervene quickly when the brake mode is switched due to the slow dynamic response of the hydraulic pressing,which affects the brake stability.The response strategy of hydraulic brake based on“feedforward&dead zone”compensation is proposed.When the electronic hydraulic brake is required to work,a pre start signal is sent to the electronic hydraulic brake first,and then the target demand brake force signal is sent to eliminate the problem of hydraulic pressure creep of the main cylinder;the hydraulic pressure of the main cylinder is compensated by the regenerative brake force of the motor in the integrated brake system to solve the problem of pressure dead zone question.Using Matlab/Simulink simulation software,the proposed control strategy is verified,and based on the hardware in the loop system experimental research,the results show that the proposed control strategy can effectively improve the responsiveness of mode switching.
