The invention discloses a predictive cruise control method and system for a fuel cell heavy truck. The method comprises the steps of determining a driving style of a driver; acquiring real-time state information of the vehicle; calculating the power of the vehicle; the power comprises hydrogen consumption power and battery consumption power; calculating the optimal driving speed of the vehicle according to the driving style, the real-time state information of the vehicle and the power of the vehicle; and performing predictive cruise control on the vehicle according to the optimal driving speed. Multi-target control is carried out according to the vehicle position, the environmental factors nearby the vehicle, the driving style of a driver, the vehicle power and the like, dynamic planning of the vehicle running speed is achieved, the flexibility and the intelligent degree of vehicle automatic driving control are improved, hydrogen consumption and power consumption in long-distance running of a heavy truck are reduced, and the safety of the heavy truck is improved. The safety and effectiveness of cruise control can be more effectively improved, and the transportation cost is reduced to a greater extent.
