This invention relates to a distributed drive mechanism and its shift control method. The distributed drive mechanism includes two drive units, each comprising a motor and a transmission component. The motor outputs power through the transmission component. The two transmission components in the two drive units share a common rotation axis, and are engaged or disengaged via a coupling clutch. When the coupling clutch is disengaged, the two drive units operate independently, providing torque vectoring capability to distribute different torques to the left and right wheels, assisting the vehicle in following the steering wheel's intent. Furthermore, since the two drive units drive the left and right wheels separately, the power requirement of a single motor is low, allowing for the selection of a smaller motor, thereby reducing motor size and weight, and lowering costs. When the two transmission components are engaged via the coupling clutch, they rotate synchronously. The two drive units are coupled together, locking the left and right wheels as a single unit rotating synchronously, achieving the function of a differential lock, which can meet the power requirements under certain operating conditions.
