The invention provides a control method of a hybrid heavy vehicle, a power system and the hybrid heavy vehicle. The control method of the hybrid heavy vehicle comprises the steps that corresponding control parameters are preset for different load states of the vehicle; and the current load state of the vehicle is obtained, and operation of a fuel cell engine, a power cell, a gearbox and a driving motor of the vehicle is controlled based on the corresponding control parameters. According to the control method of the hybrid heavy vehicle, different control parameters are set for different load states of the vehicle in advance, and the different control parameters are adopted for controlling the running states of a fuel cell engine, a power cell, a gearbox and a driving motor of the vehicle according to the different load states of the current vehicle; the actual operation power consumption requirements of the vehicle in different load states can be met in a targeted mode, so that the purpose of optimizing energy management of the power system can be achieved, and the power stability and the operation economical efficiency of the vehicle can be improved.
