The invention discloses a tandem type hybrid power control system for a heavy vehicle, which adopts a mode that a battery is directly hung on a bus and is not provided with equipment such as DC-DC (Direct Current-Direct Current) and a brake resistor, so that the complexity of the system is simplified, and the production cost and the maintenance cost are reduced; an engine throttle control scheme, a generator rotating speed control scheme, a driving motor voltage control scheme and an energy management scheme are designed, and the control method for the series hybrid power system of the heavy vehicle is designed by combining the control schemes. According to the method, the engine is directly controlled according to the driving requirement, the generator and the driving motor are responsible for adjusting the system rotating speed and the voltage state, the characteristic that the motor is higher than the engine in regulation and control capacity is fully utilized, and the problem of system state instability caused by engine power response delay is solved. According to the control method for the hybrid power system of the heavy vehicle, the functions of driving, braking energy recovery and energy management can be achieved, and the operation efficiency of the hybrid power system is improved on the premise that the stability of the system is guaranteed.
