The invention discloses a hybrid power speed change system suitable for a heavy truck and a control method, and relates to the field of automobile gearboxes. The system mainly comprises an engine and a first input assembly, wherein the first input assembly comprises the engine, an engine output shaft, a clutch Y, a first middle shaft, a first middle shaft B1 gear, a middle shaft A1 gear, a second middle shaft, a middle shaft A2 gear, a middle shaft A3 gear, a middle shaft, a middle shaft B2 gear, a middle shaft A3 gear and a second middle shaft B3 gear; the motor and second input assembly comprises a driving motor, a second input shaft, a second input shaft C1 gear, a second input shaft C2 gear, an auxiliary box high-gear gear and an auxiliary box low-gear gear; the planet row assembly comprises a sun gear, a planet carrier and a gear ring; a clutch E; a clutch R; a clutch T; a brake Q; and a brake W. According to the hybrid power speed control system suitable for the heavy truck, gear transmission is adopted, and the transmission efficiency is high; different power sources are provided or power is optimized and combined, so that the use efficiency of the power and the performance of the vehicle are improved; in addition, the invention further relates to a hybrid power method using the speed control system, and the hybrid power method comprises a gear shifting process torque supplementing mode and a reverse gear torque strengthening mode. By means of the mode, whole vehicle jerking caused by power interruption in the gear shifting process can be reduced or even eliminated, and the problem that the output torque of the transmission is insufficient in the gear reversing process is solved.
