Abstract:
1. An operation method of a hybrid vehicle having an automatic manual transmission system adapted to use at least two energy sources, the operation method comprising: engaging an engine with a starter generator motor such that the engine and the starter generator motor rotate synchronously; using the starter generator motor to start the engine serving as a first power, and using a traction motor as a second power; performing a speed changing by using a control unit assembly through controlling a rotation speed of the traction motor to a desired rotation speed for the speed changing and a rotation speed of the starter generator motor to a desired rotation speed for the speed changing according to a running state of the vehicle, such that the engine and the traction motor nearly rotate synchronously with the automatic manual transmission system to perform a gear ratio shifting process thereby to perform the speed changing; and controlling an automatic-switching clutch to engage or disengage the engine and the traction motor by using the control unit assembly through a torque/rotation speed control device to achieve a plurality of driving modes for the vehicle, wherein one of the driving modes uses the starter generator motor as an assistant power, using the control unit assembly comprising:
