The invention belongs to the technical field of hybrid power driving, and relates to a multi-mode hybrid power system with a series-parallel connection and input power split mixed mode, which comprises a first power source, a second power source, a third power source, a planetary gear mechanism, a fixed gear train, two clutches, a transmission shaft and an output shaft. Four hybrid driving modes including a single-motor parallel hybrid driving mode, a double-motor parallel hybrid driving mode, a series hybrid power driving mode and an input power split hybrid power driving mode can be achieved through the planetary gear mechanism and the two clutches, and the hybrid driving system is simple in structural form and easy to achieve. 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.
