The invention discloses a combustion limit self-learning correction method and device and a terminal, and belongs to the field of EMS system design. The method comprises the steps that combustion limit characteristics of an engine are obtained and input into a combustion limit self-learning model, and then a combustion limit correction value is obtained through output; compared with an operation scene with unfixed boundary conditions caused by environmental changes in the prior art, the method has the advantages that the combustion limit characteristics of the engine are extracted in real time, then the engine control unit judges according to the characteristic information, and the fuel consumption limit correction is compensated according to the set target; through model learning and real-time correction value output without being influenced by environment change and independent of tool vehicle conventional environment verification under manual matching, the labor cost is reduced under the condition that com
