The invention relates to the technical field of steering systems, in particular to a tail end dynamic self-learning method and system for steering execution by wire. A tail end dynamic self-learning method for executing steering by wire is characterized in that a vehicle is started, and when a steering wheel reaches the tail end leftwards or rightwards, the current TAS value is recorded as a left limit value and a right limit value; when the steering wheel returns to the middle position from the left tail end and the right tail end, the currently recorded TAS value is stored in the data storage function module; the tail end self-learning module reads numerical values and compensates the numerical values to the current use values of the left tail end and the right tail end, and angle calculation of the left tail end and the right tail end is carried out according to the current median value to be used by each functional module; and if the strokes of the left tail end and the right tail end of the rack exceed t
