The invention discloses a semi-active train control method based on a magnetorheological fluid damper. The method comprises the following steps of S1, obtaining a yaw angular velocity of a front wheel pair, a yaw angular velocity of a rear wheel pair and a yaw angular velocity of a bogie in the operation process of a train through a gyroscope; S2, processing and computing the yaw angular velocity of the front wheel pair, the yaw angular velocity of the rear wheel pair and the yaw angular velocity of the bogie in the operation process of the train so as to obtain relative yaw angular velocities of the front wheel pair and the rear wheel pair relative to the bogie; S3, obtaining relevant line information of the train operation through a vehicle data bus MVB; and S4, judging the type of a train operation line according to the relevant line information and controlling a plurality of longitudinal magnetorheological fluid dampers arranged on the train according to a train control strategy corresponding to the type of the train operation line so as to realize the control of the train. Through the adoption of the technical scheme disclosed by the invention, the stability of the train in linear operation can be effectively enhanced, the critical velocity is increased and the curve passage capacity of the train is improved.
