A hybrid power driving system includes a planetary gear mechanism having a first rotating component, a second rotating component, and a third rotating component. The system also includes an electric motor operatively coupled to the first rotating component, a clutch, an internal-combustion engine operatively coupled to the first rotating component by the clutch, and a brake operatively coupled to the second rotating component and configured to control the second rotating component in a locked position or in an unlocked position. The third rotating component is operatively coupled to an output end to provide rotational power.
