Abstract

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