This invention relates to the field of process control technology in metal material forming, and discloses an optimized control method for a wheel hub liquid forging process. A punch displacement sensor and a liquid forging pressure sensor are set up to synchronously collect and calibrate displacement and pressure signals, and perform zero-point correction to obtain a displacement and pressure sampling sequence. The displacement change rate, pressure change rate, and effective compensation displacement increment are calculated, and the filling end and compensation evaluation termination intervals are obtained according to statistical thresholds. The effective compensation displacement is accumulated within the evaluation interval, and the pressure area is obtained by integrating the pressure to construct a smoothness index. The start time of secondary pressurization, platform pressure, and duration are discretized into a candidate set to generate a target pressure trajectory that meets the pressure change rate constraint and calculates the smoothness. Optimal parameters are screened and corrected, and the pressure command sequence is output and solidified for distribution to the hydraulic system, achieving quantifiable optimization and stable execution of parameters.
