The invention relates to a vehicle-mounted hydrogen production hybrid power control system and method and a vehicle, the vehicle-mounted hydrogen production hybrid power control system comprises a hydrogen production unit, a heating unit and a control unit, the heating unit comprises a hydrogen internal combustion engine and a power battery system, and the hydrogen internal combustion engine and the power battery system are both connected with the hydrogen production unit; the control unit is connected with the hydrogen production unit and the heating unit, controls the hydrogen internal combustion engine to provide heat energy of tail gas for the hydrogen production unit and controls the power battery system to provide electric energy for the hydrogen production unit, so that the hydrogen production unit is heated to prepare hydrogen. The mode that the power battery system provides electric energy and the hydrogen internal combustion engine provides heat of tail gas to heat the hydrogen production unit has the advantages of being continuous, stable and easy to control, sufficient hydrogen can be provided for the hydrogen internal combustion engine according to the requirement of the whole vehicle, and therefore the size of the buffer tank can be reduced, meanwhile, waste heat of the tail gas of the hydrogen internal combustion engine can be recycled, and energy is saved. The heat efficiency of the system is improved.
