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.

A hybrid power drive system includes an engine, a first motor, a first clutch operatively coupled between the engine and the first motor, a first decelerating mechanism having an input portion operatively coupled between the first clutch and the first motor, where the input portion is configured to receive rotational power from the first motor and/or the engine. The first decelerating mechanism has an output portion operative to drive at least one first wheel, and a second motor is operatively coupled to at least one second wheel through a second decelerating mechanism. An energy storage device is coupled separately to the first motor and to the second motor. The engine, the first clutch and the first motor are connected in sequence, and the second decelerating mechanism and the at least one second wheel are connected in sequence. Various combinations of operating modes are provided to meet energy efficiency requirements and user power demands.

The present invention provides a hybrid power driving system, comprising: a first subsystem (401) designed to input/output power; a second subsystem (402) designed to input/output power; a driving shaft (500) designed to receive power from the first subsystem (401) and/or the second subsystem (402) or output power to the first subsystem (401) and/or the second subsystem (402); and a tri-stated overrunning clutch (400) designed to connect the first subsystem (401) and the second subsystem (402), wherein the tri-stated overrunning clutch (400) may be in an overrun state, an engaged state, or a disengaged state. The first subsystem (401) and the second subsystem (402) can comprise an engine, a motor, and a clutch, etc., respectively. In such a hybrid power driving system, when the tri-stated overrunning clutch is in the engaged state, the first subsystem (401) and the second subsystem (402) are coupled to each other and work together. When the tri-stated overrunning clutch (400) is in the disengaged state, the first subsystem (401) and the second subsystem (402) can work separately without any interference to each other. Therefore, the structure is simple and the control is convenient.
