The invention relates to the technical field of crane cart control, in particular to an automatic deviation correction control system and method for a gantry crane cart. According to the invention, the encoder is additionally arranged on the driven wheel set of the cart, the position detection devices are uniformly arranged at the joints of the rails, the walking distance of the cart is secondarily detected, the encoder is automatically reset, and the deviation control stability can be improved and the smooth operation of the gantry crane can be ensured by combining an automatic control algorithm with strict logic; the HMI technology, the PLC programmable control technology, the frequency converter control technology and the like are comprehensively applied to a mechanical drive control system, so that automatic deviation correction of a cart is achieved, and the cart can normally operate even under the condition that a track seam and a cart wheel set slip; the method is easy to implement on site, the running stability of the cart can be effectively improved, and the method is safe, reliable and convenient to operate.
