The invention discloses a fuel cell vehicle energy-saving control method based on adaptive cruise, which comprises the following steps that: an adaptive cruise system based on a model prediction control algorithm predicts vehicle speed and vehicle acceleration in a time domain in the future, and transmits the predicted vehicle speed and vehicle acceleration to an energy management system based on an ADMM algorithm; data support is provided for the system; according to the energy management system based on the ADMM algorithm, the optimal total power of a power battery is obtained through the vehicle speed and the vehicle acceleration in a time domain in the future predicted by the self-adaptive cruise control system, so that the hydrogen consumption of a fuel battery is reduced. According to the method, self-adaptive cruise and energy management are combined, and energy consumption of the fuel cell is optimized in real time.
