The invention belongs to the technical field of hybrid power vehicle power system control, and discloses a hybrid power vehicle driving system, a control system and a control method.The output end of an engine crankshaft is connected with a motor rotor shaft of a motor through a first clutch, and the output end of the motor rotor shaft is connected with an input shaft of a second clutch; an output shaft of the second clutch is connected with an input shaft of the transmission, and the output shaft of the transmission transmits power to wheels through the main speed reducer and the half shaft to drive an automobile to run. The control method comprises the following steps that the vehicle working condition is obtained, and the driving torque requirement and the engine rotating speed of each gear are calculated according to the vehicle working condition; a working mode is determined according to the driving torque requirement and the engine rotating speed of each gear; and the torque is output to the transmission mechanism in the corresponding working mode. According to the invention, the influence of the driving condition of the automobile on the work of the engine is minimized, so that the automobile realizes low emission and ultralow oil consumption, and the effects of environmental protection and energy conservation are achieved.
