The invention relates to the field of rail vehicle clearance compensation, and provides a door clearance compensator, a door clearance compensator control system and method, and a rail vehicle. The door clearance compensator control system comprises: an air cylinder used for driving a pedal body to horizontally stretch out and draw back along the bottom face of a floor body, wherein the air cylinder comprises a cylinder body and a piston stretching out and drawing back along the cylinder body, and an extending air inlet and a retracting air inlet are formed in the cylinder body and connected with air pipelines respectively; an inductive switch arranged on the air cylinder and used for inducting the position of the piston; and a controller used for controlling the extending air inlet or theretracting air inlet to intake air according to the position, detected by the inductive switch, of the piston so as to control the piston to extend to a designated position or retract to the designated position. The door clearance compensator can solve the problems that an existing door clearance compensator of a pneumatic structure is of a turnover structure, large in occupied space, complex instructure and low in reliability, the telescopic stroke of a pedal cannot be controlled, and the telescopic distance of a pedal is fixed and cannot be adjusted.

    本发明涉及轨道车辆间隙补偿领域,提供门间隙补偿器、门间隙补偿器控制系统、方法及轨道车辆。该门间隙补偿器控制系统包括气缸,用于驱动踏板本体沿地板本体的底面水平伸缩,气缸包括缸体和沿缸体伸缩的活塞,缸体上设有伸出进气口和缩回进气口,伸出进气口和缩回进气口分别连接有空气管路;感应开关,设于气缸上用于感应活塞的位置;控制器,用于根据感应开关检测到的活塞所处的位置,控制伸出进气口或缩回进气口进气,以控制活塞伸出到指定位置或缩回到指定位置。本发明能够解决现有气动结构的门间隙补偿器采用翻转结构,占用空间大,结构复杂,可靠性低,且无法实现对踏板伸缩行程的控制,踏板伸缩距离固定不可调的问题。
