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. |
