The invention relates to a locomotive intelligent control optimization calculating method based on fuzzy rules. The method includes the following steps: step 1 designing the optimization strategy for locomotive driving control and generating an optimization strategy library; step 2 extracting the key parameters in the optimization strategy; step 3 optimizing the optimization strategy parameters and performing optimized searching on the strategy parameters by means of offline large-scale searching, wherein the target of the whole optimization is that the optimization parameters with low oil consumption are selected on the basis that the running time of a locomotive doesn't exceed the planning time for three minutes; step 4 designing and realizing a strategy parameter fuzzy inference system; and step 5 performing strategy matching and execution. By searching the strategy parameters, the strategy optimization effect can be further improved.
