The invention discloses a tandem type hybrid power system which comprises an engine, a generator, a brake resistor, a high-voltage power distribution system, a driving motor and a power battery, the high-voltage power distribution system is electrically connected with the generator, the brake resistor, the driving motor and the power battery, and the power battery is arranged to be used for absorbing braking energy in a vehicle braking state. The brake resistor is arranged to be used for consuming brake energy in a brake state. According to the tandem type hybrid power system, energy generated by braking of the driving motor is preferentially absorbed through the power battery, then part of braking energy of a vehicle is consumed through mechanical rotation of the engine, the speed of consumption of the braking energy is controlled by regulating and controlling the throttle valve of the engine, and an added braking resistor is replaced; braking energy balance can be achieved, the vehicle runs stably, and the weight/space of the whole vehicle and the manufacturing cost of the whole vehicle are reduced. The invention further discloses a control method of the tandem type hybrid power system.
