针对客车制动安全性与经济性的耦合问题,基于电控制动系统(EBS)提出了一种主制动器与辅助制动系统的集成控制算法.该算法根据各制动系统的热力学特性、主制动器制动衬片的磨损量以及ECE法规,确定客车制动系统的制动力分配,在保证制动安全性的基础上兼顾了制动经济性.文中还结合Matlab/Simulink与TruckSim软件对控制算法进行了仿真验证.仿真结果表明,在下坡制动工况,所提出的制动集成控制算法能够将整车各制动器温度控制在理想值并保证各轴制动衬片磨损均衡;在水平路面制动工况,制动集成控制算法能够有效地实现目标制动强度.说明所提出的算法可有效提高客车制动工况下的安全性和经济性.

In order to integrate the security and the economy of bus braking,an algorithm integrating the control of the main brake system and auxiliary brake systems is proposed based on the EBS （Electronic Controlled Braking System）.In this algorithm,according to the ECE regulation,the wear loss of brake linings and the thermodynamic properties of brake systems,the braking force is rationally distributed among the brake systems of the bus,thus achieving the economy on the premise of brake security.Moreover,based on the co-simulation platform of Matlab/Simulink and TruckSim,the proposed algorithm is verified by simulations.The results show that,during the down-hill braking,the algorithm helps to keep the temperature of brake systems at an optimal value and facilitate a ba-lance wear of brake linings;and that,during the level-road braking,the algorithm helps to achieve the desired bra-king force effectively.It is thus concluded that the proposed algorithm is feasible in improving the security and the economy of bus braking.
