摘　　要：机车制动机根据目标压力控制均衡风缸压力,均衡风缸通过中继阀控制列车管充排风动作实现机车的制动与缓解。因中继阀的迟滞性,制动机无法精准控制列车管压力,影响机车速度控制与平稳驾驶。分析了中继阀迟滞性,提出了制动机自动获取中继阀的迟滞值并自适应调整目标压力的方法,最终实现列车管压力的精准控制。The ER of locomotive brake is controlled by the target pressure,and the BP is charged or exhausted based on the ER by the relay valve to realize the braking and release of locomotive.Due to the hysteresis of relay valve,the brake can’t control the BP accurately,which affects the speed control and smooth driving of locomotive.The hysteresis of the relay valve is analyzed,and a method for the brake to obtain hysteresis value of relay valve automatically and adjust the targeted ER adaptively is proposed to realize the precise control of the BP pressure.
