The invention provides an ammonia-hydrogen zero-carbon internal combustion engine hybrid power system energy management strategy based on model predictive control. A hybrid power system comprises an ammonia-hydrogen internal combustion engine controller, an ammonia-hydrogen internal combustion engine, a generator, a generator controller, a motor controller, a power coupler and a driving motor. The whole vehicle controller obtains the whole vehicle power demand at the current moment, predicts the vehicle speed in the future s time, obtains the whole vehicle SOC constraint in the future s time based on the whole vehicle model and adjusts the volume fraction alpha of the mixed fuel gas occupied by the ammonia gas of the ammonia-hydrogen engine in real time, and finally obtains the optimal engine output power sequence through a model prediction control algorithm. Fuel consumption is reduced, the efficiency of the zero-carbon hybrid power system is improved, and the problem that in a rule-based control strategy, an optimal control method is difficult to put forward for complex working conditions due to excessive dependence on experiences of engineers is solved.
