The invention belongs to the technical field of hybrid power driving, and relates to a multimode hybrid power system with seven hybrid power driving modes, which comprises three power sources, two planetary gear mechanisms, a fixed gear train, three clutches, a transmission shaft and an output shaft. According to the invention, the two planetary gear mechanisms and the three clutches are arranged; a single-motor parallel hybrid power driving mode, a double-motor parallel hybrid power driving mode, a series hybrid power driving mode, an input power split hybrid power driving mode, an output power split hybrid power driving mode and a single-rotating-speed decoupling hybrid power driving mode are achieved. The dual-rotating-speed decoupling hybrid power driving mode comprises seven hybrid power driving modes. Compared with an existing multi-mode hybrid power system, the system has the advantages of being multiple in hybrid power driving mode, simple in structural form, good in energy-saving potential of the system in the whole working condition domain of the whole vehicle and the like.
