Trailer brake control optimization method based on TEBS system

The invention discloses a trailer brake control optimization method based on a TEBS system. A travel sensor is used for collecting a signal generated when a driver actuates a brake pedal, an air inlet pressure sensor is used for collecting an absolute pressure signal in an air inlet manifold, and an ABS sensor is used for collecting a rotating speed signal of wheels during emergency brake; the deceleration required by a driver is calculated and judged and transmitted into the central ECU, and a brake pressure signal of a brake chamber required by the corresponding brake deceleration is output by combining the weight of the whole vehicle, the load of each corresponding trailer axle and the brake torque under the unit pressure of a brake; feedback adjustment of neural network fuzzy control is added between a deceleration signal and a brake pressure signal, a fuzzy control neural network model is adopted, deceleration signal deviation is optimized, and the influence of internal and external disturbance on a cont
