The invention relates to an optimized brake pressure control method, which comprises the following steps of: constructing a database in which slip rates and combination coefficient curves are stored: (1) drawing the curves of the slip rates and the corresponding combination coefficients under the condition that the forward speed of an axle and the load on an airplane wheel are kept unchanged, and (2) drawing the curves of the slip rates and the corresponding combination coefficients under the condition that the load on the airplane wheel is kept unchanged; and (3) adjusting the load on the airplane wheel, and executing the step (2) under different loads to draw the corresponding three-dimensional curved surface diagram, namely adjusting the forward speed of the wheel shaft, and executing the step (1) to draw the curve of the corresponding slip rate and the combination coefficient and generate the three-dimensional curved surface diagram containing the speed, the slip rate and the combination coefficient at different forward speeds of the wheel shaft, and executing the step (2) under different loads to draw the corresponding three-dimensional curved surface diagram. Generating a four-dimensional curved surface diagram containing the load, the speed, the slip rate and the combination coefficient; (4) storing the four-dimensional curved surface diagram into a database; calculating the maximum brake pressure based on the slip rate and the combination coefficient curve; the brake pressure of the wheel is controlled based on the maximum brake pressure.
