The invention is suitable for the technical field of rail transit vehicles, and provides a train antiskid control method and device, and the method comprises the steps: obtaining a first speed threshold value and a second speed threshold value of a train according to the operation condition of the train, a current road condition, a preset speed difference threshold value and a preset wheel set slip rate threshold value; according to the obtained train speed at the current moment, the obtained train wheel set speed at the current moment, a first speed threshold value and a second speed threshold value, obtaining an initial anti-skid control instruction corresponding to the current moment; according to the current train wheel set deceleration obtained based on the current train wheel set speed and the current train wheel set deceleration change rate, adjusting the initial anti-skid control instruction for the first time; and carrying out anti-skid control on the train according to the initial anti-skid control instruction after the initial adjustment. According to the method, anti-skid control is carried out on the train, the dynamic adaptability and accuracy of the initial anti-skidcontrol instruction can be ensured, and accurate control of train anti-skid braking is realized.
