分析现有动车组电空制动控制系统中的制动力分配策略，针对动车与拖车电空制动力施加不均的问题，提出一种电空制动协调控制优化策略。采用动车电制动优先的控制原则，并根据载重反比分配拖车与动车所需施加的空气制动力。以 CRH2型动车组中一动一拖为基本单元，利用Matlab/Simulink软件对列车在不同制动工况进行仿真，结果表明，基于载重反比分配制动力的电空制动协调优化控制策略可有效提高列车制动效率，减小动车与拖车的车轮踏面磨损。

On analysis of the braking force distribution strategy in existing Electric Multiple Unit(EMU) electro-pneumatic braking control system, an optimization strategy of electro-pneumatic braking cooperative control is proposed, which aims at solving the imbalance problem of the motor car and trailer car’s electro-pneumatic braking. It uses electro-pneumatic braking priority control principle in EMU, and distributes air braking force of motor car and trailer car in inverse ratio on the basic of load. By modeling the EMU electro-pneumatic cooperative braking control and braking force distribution optimized algorithm while taking one motor car and one trailer car in CRH2 EMU as the basic unit, the Matlab/Simulink software is used to simulate different braking condition. The results indicate that the electro-pneumatic cooperative braking control optimization strategy which based on the load inverse-proportion for braking force distribution has the significant effect on improving brake efficiency, reducing wheel tread wear of the motor car and the trailer car.
